    TECHNICAL FIELD
    [001] This disclosure concerns a method on a network node, a method on user equipment, a network node and user equipment on a wireless communications network. More particularly, mechanisms for control based on a network of report messages are provided, which comprise measurements recorded on a wireless communications network. FUNDAMENTALS
    [002] In a typical cellular radio system, wireless terminals, also known as mobile stations and / or user equipment units (UEs), communicate through a Radio Access Network (RAN) to one or more major networks. Wireless terminals, hereinafter called UEs, which is the same as user equipment, can also be mobile phones, that is, “cell phones”, and lap computers with wireless capability, for example, mobile termination, and, therefore, they are, for example, portable, pocket, handheld mobile devices, included in a computer, or mounted in a car that communicate voice and / or data through the RAN.
    [003] The RAN normally covers a geographical area that is divided into cell areas, also called cells, with each cell area being served by a base station, for example, a Radio Base Station (RBS), which in some networks it is also called “NóB” or “NóB”. A cell is a geographical area where radio coverage is provided by base station equipment at a base station location. Each cell is identified by an identity within the local radio area, which is broadcast in the cell. The base station communicates over the air as an interface operating on radio frequencies with the UEs within the boundaries of the base stations.
    [004] In some versions, particularly earlier versions of the RAN, several base stations are typically connected, for example, by land lines or microwaves, to a Radio Network Controller (RNC). The RNC, also sometimes called a Base Station Controller (BSC), supervises and coordinates various activities of the plural base stations connected to it. Radio Network Controllers are typically connected to one or more major networks.
    [005] The Universal Mobile Telecommunications System (UMTS) is a third generation mobile communication system, which has evolved from the Global System for Mobile Communications (GSM), and is designed to provide improved mobile communication services based on Multiple Access by access technology Broadband Code Division (WCDMA). UTRAN is essentially a Radio Access Network that has multiple access by broadband code division for user equipment units (UEs). The Third Generation Partnership Project (3GPP) has undertaken to further evolve access network technologies based on UTRAN and GSM radio.
    [006] Long Term Evolution (LTE) is a variant of a 3GPP radio access technology in which the radio base station nodes are connected directly to a main network instead of the RNCs. In general, in LTE the functions of the RNC node are performed by the RBSs. As such, the RAN of an LTE system has an essentially “flat” architecture that comprises RBSs without reporting to RNCs. In LTE networks the base station (s) is / are called eNóB (s) or eNB (s).
    [007] 3GPP is in the process of defining solutions for Minimizing Driving Tests (MDT). The intent of the Driving Test Minimization (MDT) work is documented in 3 GPP TR 36,805 V9.0.0 (2009-12), 3rd Generation Partnership Project; Technical Specification Group Radio Access Network; Study on Minimization of drive-tests in Next Generation Networks (Release 9). Stage 2 of Minimizing Driving Tests (MDT) is currently being developed in TS 37.320, that is, 3GPP TS 37.320, “Radio measurement collection for Minimization of Drive Tests (MDT); Overall description; Stage 2 ”. Stage 2 of the MDT includes a UE measurement recording function and an immediate reporting function. The 3GPP TS 37.320 document essentially focuses on the EU measurement recording function. An important use case for MDT is coverage optimization. For this purpose, the following UE measurements, or similar functionalities, are considered for internal registration to the UE: Periodic downlink pilot signal strength measurements, for example, one every 5s; a serving cell becomes worse than the limit; transmission power maneuverability becomes less than the limit; Paging Channel Failure, that is, Paging Control Channel (PCCH) decoding error; e Diffusion channel failure. The network can request the UE to perform measurement records. The UE performs measurements and records these measurements internally in a sequential manner, containing, for example, some hour of recorded measurement information.
    [008] As described in Figure 1, the UE indicates to the network if the same record is available, that is, recorded measurements available. The network node, that is, eNB / RNC determines whether it should request the recorded measurements or not. If he decides to do so, then a request is sent to the UE to deliver the record in a report message. From the eNB / RNC, the reported recorded measurements can be additionally sent to an OAM or similar server.
    [009] The current 3GPP assumptions about this recording facility (ie, recorded measurements) are, for example, as follows: the UE is required to maintain only one record at a time; a record contains only measurement information collected from a Radio Access Technology (RAT); a record can only be reported and indicated when the UE is in a connected state; if the UE is asked to start recording, for example, by configuration, a possible old record and configuration stored in the UE is deleted.
    [0010] What the measurement report message recorded in signal number 4 in Figure 1 should look like has not yet been decided, when filing this order. Some proposals for management of measurement reports have been presented.
    [0011] As an example of a proposal for management of measurement reports, it has been suggested that a record, that is, recorded measurements, should be sent in a single package, and keeping this single package within the size limits of a measuring unit. Protocol Data (PDU) of Packet Data Convergence Protocol (PDCP). Keeping the single packet within the size limits of a PDCP PDU makes it possible to use an RRC Radio Resource Control message to report without being segmented into several smaller packets before being sent to the receiving node, that is, the eNB or NB / RNC in LTE or UMTS, respectively. One option of this proposal would be to limit the maximum size of a record in a UE to an RRC message that fits within a PDCP payload packet.
    [0012] As another example of a proposal for management of measurement reports, it has been suggested to send a record, that is, a recorded measurement that is larger than an RRC message with several RRC messages.
    [0013] However, there are disadvantages for both proposal examples mentioned above. For example, limiting the size of the log could prevent the log from completing for the configured full run time, that is, the log duration, which can be several hours. The record could fill the limited record buffer buffer in the UE before it was possible to send any measurement report to the network node. Before the configured duration of the logging time has ended, the UE should stop logging to allow the logging size to be only a single package, for example, a single RRC package, and important measurement reports thereafter cannot be logged. Also in the current MDT configuration, a start time for registration is not configurable. This means that for an extended registration campaign a long period between registration instances may be required in the MDT configuration, alternatively a new MDT configuration needs to be provided from the OAM periodically to transport MDT-enabled UEs.
    [0014] For the other proposal, sending too many RRC packets in sequence could, in bad radio environments or when transfer should occur, create problems with radio connections and could also create unnecessary radio link failures that will make users suffer and data registered to be lost.
    [0015] Additional details of the 3GPP proposals can be found in Ericsson and others, “Further details on logged MDT measurement reporting”, 3GPP Draft, R2-103086, May 4, 2010 (measurement reports can be sent in segments) and in Kyocera, “Inter-RAT MDT data retrieval and MDT (re) -configuration”, 3GPP Draft, R2-104813, August 17, 2010 (EU sends available registered MDT data indicator).
    [0016] Additionally, international patent application number WO 2006/016690 reveals a field in a channel quality report that indicates a degree of mobility from which the base station must be able to deduct how many additional reports will follow. SUMMARY
    [0017] The technology disclosed in this document relates to network-based control of report messages that comprises measurements recorded on a wireless communications network, which overcomes at least some of the disadvantages mentioned above and which allows multiple partial report messages to be sent.
    [0018] According to some exemplary modalities, a UE that has recorded data stored, that is, recorded measurements that are larger than a single transmission packet, that is, a report message, segments the data and sends only a part of the data that fits within a single report message, and also indicates that there are more measurements recorded in the UE.
    [0019] In a first exemplary embodiment, a method on a network node for network-based control of report messages on a wireless communications network is disclosed. Where the network node is configured to serve a user device, UE, and to receive report messages from the user device. The method comprises sending a request to the UE to start transmitting measurements recorded in a report message. The network node then receives the report message that comprises the recorded measurements from the UE, and determines whether the received report message comprises an indicator of additional recorded measurements not yet transmitted, and if so, decides whether the additional recorded measurements need to be requested.
    [0020] In a second example of a modality, a network node for network-based control of report messages on a wireless communications network is revealed. The network node is configured to serve a user device, UE, and to receive report messages from the user device. The network node comprises a network node communications interface and a network node processor circuit. The network node communications interface is configured to send a request to the UE to start transmitting measurements recorded in a report message, and to receive the report message that comprises the recorded measurements. The network node processor circuit is configured to determine whether the report message received comprises an indicator of additional recorded measurements not yet transmitted; and if so, to decide whether additional recorded measurements need to be requested.
    [0021] In a third example of a modality, a method is revealed in a user equipment, UE, to assist in the network-based control of report messages in a wireless communications network. The UE is connected to a server network node and configured to transmit report messages to the network node as a result of a request. The UE is additionally configured to perform radio condition measurements periodically and store the measurements made periodically in a UE buffer buffer as recorded measurements. In which the method comprises: receiving a request, at the UE, from the network node to initiate the transmission of measurements recorded in a report message; determine whether the recorded measurements fit the report message; and if not, include in the report message an indicator of additional recorded measurements not yet transmitted; and, transmit the report message, which comprises the indicator, to the network node as a response to the request.
    [0022] In a fourth example of a modality, a user equipment, UE, is revealed to assist in a network based control of report messages on a wireless communications network. The UE is in connection with a server network node and is configured to transmit report messages to the network node. The UE is additionally configured to perform radio condition measurements periodically and store the measurements made periodically in a buffer buffer as recorded measurements. The UE comprises an UE communications interface and an UE processor circuit. The UE communications interface is configured to receive a request from the network node to initiate the transmission of measurements recorded in a report message, and to transmit the report message comprising the recorded measurements. The UE processor circuit is configured to determine whether the recorded measurements fit in the report message, and if not, indicate in the report message to be transmitted the existence of additional recorded measurements not yet transmitted.
    [0023] An advantage obtained by certain aforementioned modalities is that due to the use of an indicator in a report message of additional remaining recorded measurements to provide the network, that is, a network node, with the information necessary to decide a transmission synchronism. recorded measurements and a timing of when more recorded measurements should be requested. Another advantage obtained by at least some of the aforementioned modalities is to make it possible to have a longer recording duration and / or to conduct more frequent measurements without overloading the registration memory in the UE, for example, UE buffer buffer.
    [0024] Another advantage obtained by certain aforementioned modalities is to provide information to the network node about recorded measurements making it possible to determine the amount of recorded measurements maintained in a UE.
    [0025] The foregoing and other characteristic features and advantages will become more evident from the more particular descriptions of modalities and aspects of modalities to be followed as illustrated by the attached drawings in which the reference characters refer to the same parts throughout. views.

    [0033] Figure 2 illustrates parts of an exemplary modality of a communications system / network, and particularly parts of a Radio Access Network (RAN) 20 comprising at least one network node 28 and a wireless terminal, from here hereinafter referred to as user equipment, (UE) 30. Depending on the particular type of RAN used and delegation of nodal responsibilities, network node 28 can be a base station node, for example, a NodeB in UMTS or an eNodeB in Long Term Evolution (LTE) or a Radio Network Controller (RNC) node in UMTS. Therefore, the UE 30 communicates over the radio interface 32 with the network node 28, or directly over the radio interface 32 with the network node 28 in case the network node 28 is a base station type node, or over the radio interface 32 and through a base station in case network node 28 is a Radio Network Controller (RNC) node or a Mobility Management Entity (MME) which is a control node that processes signaling between the UE and the Main Network (CN) and provides Visitor Location Record (VLR) functionality for the Evolved Package System (EPS). As mentioned above, the UE 30 can be a mobile station such as a mobile phone (“cell phone”) or lap computer with wireless capability (for example, mobile termination), and therefore can be, for example, a mobile device portable, pocket, handheld, included in a computer, or mounted in a car that communicates voice and / or data through a radio access network.
    [0034] According to one of its aspects, the technology revealed concerns the generation and / or transmission and / or use of multiple partial report messages with recorded measurements such as MDT record packages, also denoted MDT record or record data MDT. As such, Figure 2 shows an exemplary network node 28 or UE 30 embodiment, comprising a communication interface of UE 42 and a processor circuit of UE 40. It should be noted that the UE can be seen as a server point. The UE processor circuit may include a buffering buffer 44, i.e. buffer buffering buffer UE, to store recorded measurements, not shown in the figure, and in another embodiment buffer buffering memory 44 is within the UE 30.
    [0035] Figure 2 also illustrates network node 28 as comprising a network node processor circuit 50 and network node communications interface 52 (i.e., a network node communication interface). The network node processor circuit 50 can be, or comprise, a recorded measurements requester / processor (not shown in the figure) to be used to request recorded measurements, such as MDT record, in report message (s).
    [0036] According to an example of a modality, network node 28 is used for network based control of report messages comprising measurements recorded on a wireless communications network, where network node 28 is configured to serve the UE 30, UE, and to receive report messages from the UE 30. Continuing with the description in Figure 2, the network node communications interface 52 is, or can be, configured to send request (s) to the UE 30 to start transmitting the measurement (s) recorded in the report message (s), and to receive the report message (s) that comprise the recorded measurements. The recorded measurements can comprise one or more of the following: temporal measurement records for each measurement performed; UE buffer buffer status condition; UE positioning information; downlink pilot signal strength measured periodically; conditions of the server cell; space conditions for transmission power maneuvers; paging channel failure (s); maximum required memory supported by the UE; and diffusion channel failure (s).
    [0037] According to one embodiment, the network node communications interface 52 can be configured to receive, from the UE 30, an indication of the existence of recorded measurements that are available. It should be noted that the “additional recorded measurements” indicator is carried in the UE report message information while the available registered measurements indication is carried on already existing / specified signaling.
    [0038] According to one embodiment, the network node communications interface 52 can be configured to request the report message (s) directly from the UE 30 or from another network node, for example, RNC, MME , RBS or other similar node.
    [0039] According to an embodiment, the network node communications interface 52 can be configured to request the report message as a result of receiving an access request from the UE initiated by an UE transfer procedure from another network node to the network node. The request can, for example, be an RRC connection request. The network node communications interface 52 can also be configured to receive a network node message from the other network node, that is, another eNodeB, RNC or RBS, which comprises UE specific information. The specific information from the UE may additionally comprise the indicator to indicate additional recorded measurements not yet transmitted.
    [0040] The network node processor circuit 50, mentioned above in relation to Figure 2, is configured to determine whether the report message (s) received (s) comprises (s) an additional measurement indicator (s) registered (s) not yet transmitted; and if so, decide whether additional recorded measurements need to be requested. According to one embodiment, the network node processor circuit 50 can be configured to decide whether additional recorded measurements need to be requested based on one or more of the following: level of interference experienced in a cell; measurements of radio condition experienced in a cell; radio resource available; network node capacity; UE buffer buffer status condition etc. According to one embodiment, the network node processor circuit 50 can be configured to determine whether the indicator indicates that there are measurements recorded in a UE buffer buffer 44 that fit, or do not fit, in a single subsequent report message.
    [0041] According to one embodiment, the network node processor circuit 50 can be configured to decide to request all measurements recorded in the buffer buffer 44 of the UE in a subsequent request, or repeatedly as a result of receiving each report message. . The decision can also be based on status information received from buffer buffer 44 in the UE 30 being, for example, overloaded. It should be noted that configured for or adapted to in relation to the functionality of circuits and devices mentioned above and throughout the disclosure are expressions that can be used with the same meaning or a similar meaning.
    [0042] It must be assessed that the network node 50 processor circuit may comprise an MDT 50 'requestor / processor register (not shown in Figure 2) that can be implemented in the form of a platform, for example, implemented by a computer / processor that executes instructions for non-transient signals and / or for a circuit. Also from a perspective of the UE, reference made to Figure 2, the UE 30 can be, or is, used to assist in network-based control of report messages that comprise measurements recorded on a wireless communications network. The UE 30 is connected to the server network node 28 and is configured to transmit report message (s) to the network node 30. The UE 30 can be additionally configured to periodically perform radio condition measurements and store the measurements taken periodically in the buffer buffer 44 as recorded measurements. These recorded measurements can be MDT record reports.
    [0043] The communication interface of UE 42 mentioned above in relation to Figure 2, is configured to receive a request from network node 28 to initiate the transmission of measurements recorded in report message (s), and for (a) report message (s) comprising the recorded measurements. The UE 40 processor circuit is configured to determine whether the recorded measurements fit into the report message (s), and if not, indicate in the report message to be transmitted an existence of additional recorded measurements not yet transmitted.
    [0044] According to an exemplary implementation embodiment of a UE 30 in which the UE 40 processor circuit can be, or can comprise, a partial partial MDT recorder 40 '(dashed lines of Figure 2). The multiple partial MDT record reporter 40 'may comprise a record report generator and data recording unit (not shown in Figure 2). The multiple partial MDT recorder 40 'works in conjunction with a measurement unit (not shown in Figure 2), and stores measurement records in the data recording unit. The log report generator may additionally comprise a packet identifier generator and “more data”, that is, additional data, a flag generator. The technology revealed above, and in relation to any of the aforementioned modalities, includes support for recorded measurements, or an MDT record size, which exceeds a maximum report message size that may, for example, be a Convergence Protocol package. of Packet Data (PDCP). The technology disclosed in this document also introduces and provides an UE 30 indication of additional recorded measurements or MDT record data that remain in the UE 44 buffer buffer. According to some exemplary modalities, an UE 30 that has recorded measurements stored, some times denoted recorded data, which is larger than a single report message, that is, transmission packet, segments the recorded measurements, and sends only a portion of the recorded measurements that fit within a single report message. The UE 30 also indicates that there are more measurements recorded in the UE 30 in the buffer buffer 44. This indication of additional remaining recorded measurements allows network node 28 to decide a transmission timing of the recorded measurements and a timing of when more measurements are recorded. must be requested. This may, for example, depend on radio condition measurements or UE buffer buffer status information.
    [0045] The UE 30 will take a part of the recorded measurements and place it within the payload of the report message. The UE 30 will, if more recorded measurements are still available, determine a “plus” or “additional” bit to indicate to network node 28, or otherwise indicate to network node 28, that there are more recorded measurements available in UE 30. Network node 28 will then, when it believes that more data should be obtained, for example, based on: level of interference experienced in a cell; measurements of radio condition experienced in a cell; radio resource available; network node capacity; UE buffer buffer status condition etc., request more recorded measurements. When a request is made then the process can be repeated. A new decision can be made after a new report message is received, and so on. In other words, as a result of receiving UE indication, network node 28 makes a decision (based on current radio conditions, node capacity) that network node 28 should request more “data” from recorded measurements from the UE now or request them at a later point in time. This “later point in time” could be predefined, for example, 15s later. In one example, an internal algorithm can, for example, verify that no Transfer (HO) is imminent or another more vital procedure is at hand. Report messages can be lost if unsuccessful reporting occurs just before an HO. In one example, network node 28 can be configured to continue requesting the reporting of recorded measurements (MDT records) in report messages until there are no more recorded measurements for reporting.
    [0046] An example of a modality of a method that can be implemented on network node 28 is illustrated by Figure 3. The method is used for network-based control of report messages comprising measurements recorded on a wireless communications network . According to the method, the network node 28 being configured to serve a UE 30, receives report messages from the UE 30 as mentioned above in relation to Figure 2. More particularly, the method comprises: sending S62 a request to the UE to start transmitting measurements recorded in a report message; receive S64 the report message that comprises the recorded measurements; determine S66 if the report message received comprises an indicator of additional recorded measurements not yet transmitted; and if so, decide S68 if additional recorded measurements need to be requested.
    [0047] Still an example of a modality of a method for implementation in network node 28 is illustrated by Figure 4. The common steps, that is, S72, S74, S76 and S78 correspond to S62 to S68 mentioned above. In this example the method comprises the network node 28 first receiving S71, for example, from the UE 30, an indication of the existence of recorded measurements that are available, that is, the buffer buffer of UE 44 is not empty or there is more data in EU 44 buffer buffer. It should be noted that this indication is different from the indicator to indicate additional recorded measurements. According to the method, network node 28 decides to send S72 request to UE 30 to initiate reporting and receives S74 a report message as a response. Network node 28 then determines whether the reporting message, which also comprises recorded measurements and reporting time recording, comprises an indicator of additional recorded measurements not yet reported. If so, network node 28 can decide S78 to request these additional recorded measurements, and therefore restart at S72. If no indicator is included, network node 28 will wait for S77 for a new indication S71, and will restart the procedure at S72. Network node 28 as a result of deciding S78 to request additional recorded measurements may decide to request S79 for all measurements recorded in a decision instead of requesting a report message at a subsequent time. In some exemplary embodiments, if the UE 30 indicates that more than one report message is required for the measurements recorded in its UE 44 buffer buffer, then several bits can be used to indicate this. Network node 28 can then choose to request multiple messages if network node 28 so wishes.
    [0048] From the perspective of a UE, and an example of a modality that illustrates a method in a UE, reference is now made to Figure 5. The UE 30 is configured to periodically perform radio condition measurements and store the measurements made periodically in a buffer of EU 44 buffer as recorded measurements. The method at UE 30 to assist in network-based control of report messages comprising measurements recorded on a wireless communications network, comprises: receiving S82 a request from network node 28 to initiate transmission of measurements recorded in a message. report; determine S84 if the recorded measurements fit the report message; and if not, include S86 in the report message an indicator of additional recorded measurements not yet transmitted; and, transmitting the S88 report message, which comprises the indicator, to network node 28 as a response to the request (S62; S72).
    [0049] In an example of an EU modality and mode, the technology revealed in this document encompasses the following actions and capabilities, as illustrated by Figure 6.
    [0050] S90: UE periodically takes measurements and records radio condition measurements, and possibly detailed positioning information for the UE 30, and stores the measurements as measurements recorded in the UE's buffer buffer 44, that is, in the internal memory of the UE 30.
    [0051] According to a modality, measurements recorded in EU 44 buffer buffer can be accumulated as "records" that include a "time record" indicating the time when the radio measurement was taken, that is, "record measurement time ”and recorded measurements. Optionally, the record can also include detailed position information for the UE's geographical position. The “records” can be of variable size. The size of the recorded measurements, sometimes referred to as the record size, in UE 44 buffer buffer can be larger than it is possible to fit within a single report message to be sent from the UE to the network node.
    [0052] S92: When UE 30 receives a request from network node 28 to start transmitting / reporting recorded measurements, UE 28 takes the number of “records”, IE, recorded measurements, from UE 44 buffer buffer, that is, internal records, typically in the order of storage, that fit within the report message, and “advance” an internal pointer so that the “records” stored next will be included in the next report message the next time the UE 30 is asked to report recorded measurements.
    [0053] This step, that is, S92, can be preceded by the one in which the UE 30 sends S91 an indication to the network node 28 making it aware of recorded measurements that are available in the UE 28.
    [0054] S94: As a result of receiving (S92) a request to start transmission the UE 30 then determines whether the recorded measurements fit into a single report message or not.
    [0055] If the recorded measurements fit into a report message then no indicator is added or a dedicated bit for the indicator is left empty, that is, null is sent in that bit. Alternatively, an indication is added stating that no further information is available.
    [0056] S96: In case the UE 30 has more recorded measurements (“records”) stored in the buffering memory of UE 44 not yet reported, an indicator of “additional recorded measurements” is included in the report message, ie , there is more data.
    [0057] A value of “Time record”, that is, “Report time record” or another identifier is added to the report message in the transmission of the report message. Alternatively, instead of including a report timestamp within the report message, a sequential number, scaled by one, can be used for each report message transmission. It should be noted that this reporting time record is different from the measurement time record added as a result of performing and recording the measurement.
    [0058] S98: UE 30 then transmits the report message, including the oldest recorded measurements obtained from UE 44 buffer buffer, to network node 28 as a response to the request. The report message can therefore comprise recorded measurements, a report time log and detailed positioning information from the UE 30.
    [0059] S99: The UE 30 then removes the recorded measurements transmitted / reported from its buffer buffer memory, that is, buffer buffer buffer of UE 44, and “advances” an internal pointer so that the “records” stored at The following will be sent in the next report message. After receiving a new request from network node 28, the UE 30 can then transmit / report recorded measurements, that is, repeat steps S92 to S99 and include new recorded measurements, that is, “records”, of the buffer buffer memory of UE 44, according to its internal pointer. Alternatively, or in combination with the report, the UE 30 can start again at step S90.
    [0060] It should be noted that in the current implementation of “MDT” measurement records as recorded measurements can be made only when UE is in the “available” state and sending recorded measurements (MDT records) in report messages can be done only when the UE is in the “connected” state.
    [0061] In some exemplary embodiments, if the EU 44 buffer buffer is almost full or if a size limitation is to be reached, the UE 30 can indicate these conditions to network node 28 during S91 sending or add that information during S96 and send it during S98. The network node 28 can then prioritize the recovery of recorded measurements in order not to stop recording and / or to lose recorded measurements.
    [0062] During the repeated sequence of messages between UE 30 and network node 28, to carry complete recorded measurements from UE 30 to network node 28, there may be a need to change the cell and / or Base Station (BS ) server, for example, during a transfer from a first BS (eNB1; NB1; RNC1; RBS 1) to a second BS (eNB1; NB1; RNC1; RBS 1).
    [0063] One way to deal with cell change and / or BS change situations is one in which the UE indicates availability when it is even connected to the second BS, for example, according to S91 in Figure 6. Therefore the UE 30 being served by a first BS (for example, eNB1) and that has sent, for example, two report messages to the first BS, when making a transfer it starts by sending an indication, that is, it sends S91 indication of available recorded measurements, to the second BS (for example, eNB2) and then as a result of the request starts to report a third report message to the second BS. Recorded measurements that are sent in the first and second report messages are generally removed from the EU 44 buffer buffer, and therefore are no longer available.
    [0064] A second, or alternative, way of dealing with this situation is one in which the information that the first BS (for example, eNB1) has received with respect to “recorded measurements available” as from step S91, is transferred to the second BS (e.g., eNB2). The information is transferred based on a request from the second BS or automatically, including any related information such as tracking references, etc. The idea here is to include the “indication” in the existing / specified transfer preparation flag (between eNB1 and eNB2) that is “preparing” eNB2, before the UE is actually transferred (commanded) from eNB1 to eNB2.
    [0065] In some situations, indications of “tracking references” and “recorded measurements available” (S91) can be forwarded between RAN 20 nodes. In these cases, the UE 30 can also include tracking references in the report message when the UE 30 transmitting a first report message to a RAN node after the transfer. It should be noted that this first report message, like the one mentioned above in relation to the first way of handling the situation, must be the third report message.
    [0066] Therefore, the technology disclosed in this document, in one of its aspects, supports and / or facilitates that a record size exceeds a maximum size of a report message, for example, a PDCP packet. If report loss / performance is considered a problem and needs to be addressed, at the same time that a full EU record size restriction, in UE buffer buffer or UE memory, is not desired, then the UE that has recorded measurements stored, that is, recorded data, that are larger than a single PDU payload (for example, due to the PDCP restriction) can segment the recorded measurements and send only a portion that fits within a single message / report package, for example, a message size in the UE reply message has a fixed size while the MDT record itself has another limit, for example, UE buffer buffer size restriction in UE 30 etc. To address this, an indication is provided in the report message, for example, the EU MDT record report, in which there are additional / more measurements recorded. This allows the network node 28 to decide the timing for when measurements should be requested and / or (re) configured. If relying only on the “available report bit” requires the UE to switch back to connected RRCs which may delay the transfer of additional recorded measurements, possibly involving the UE record memory being emptied, new MDT configuration registered or transfer (HO) to another Radio Access Technology (RAT) etc.
    [0067] Therefore, with a report message size restriction, the UE 30 must be able to split the measurements recorded within a fixed maximum report message size, for example, an RRC message.
    [0068] Currently the RRC message for MDT also carries information for RACH (SON) optimization and other optionally configured information. A consequence of the presence of other information in the RRC / PDU message using a size restriction must be that it possibly depends on the construction and configuration of the RRC message, or that the maximum size of a report message is always determined according to a scenario. worst case.
    [0069] In view of the above reasons, no special handling of the RRC / record message size should be necessary as a result of MDT. Maintain normal handling of RRC messages, etc. simplifies the considerations that need to be taken on network node 28 and EU 30.
    [0070] The technology revealed in this document provides several advantages. Among the advantages are the following. The technology allows long record execution times that can create large sizes of recorded measurements while network node 28 controls the reporting time. The technology makes it easier for network node 28 to be able to determine an appropriate reporting time without losing recorded measurements.
    [0071] It will be assessed by those skilled in the art that the block diagram in Figure 2 in this document may represent conceptual views of sets of illustrative circuits or other functional units that incorporate the principles of technology. Similarly, it should be assessed that any flowcharts such as from Figure 3 to Figure 6, state transition diagrams, pseudocode, and the like represent various processes that can be represented substantially in a computer-readable medium, and therefore executed by a computer or processor, whether or not the computer or processor is shown explicitly.
    [0072] Functions of various elements include functional blocks of Figure 2, including, but not limited to, those labeled or described as "computer", "processor" or "controller", can be provided through the use of hardware such as hardware circuit and / or hardware capable of executing software in the form of coded instructions stored in a computer-readable medium. Therefore, these illustrated functions and functional blocks must be understood as being either implemented by hardware and / or implemented by computer, and therefore implemented by machine.
    [0073] In terms of hardware implementation, the function blocks of network node 28 or UE 30 may include or include, without limitation, hardware of Digital Signal Processor (DSP), reduced instruction set processor, circuit set of Hardware (for example, digital or analog) includes not limited to Application Specific Integrated Circuit (s) [ASIC], and (where appropriate) state machines capable of performing these functions.
    [0074] In terms of computer implementation, a computer is generally understood to comprise one or more processors or one or more controllers, and the terms computer and processor and controller can be used interchangeably in this document. When provided by a computer or processor or controller, functions can be provided by a single computer or dedicated processor or controller, by a single computer or shared processor or controller, or by a plurality of individual computers or processors or controllers, some of which can be shared or distributed. In addition, the use of the term "processor" or "controller" should also be interpreted as referring to other hardware capable of performing these functions and / or running software, such as the exemplary hardware listed above.
    [0075] In the example in Figure 5, the platform represented by line 70 was illustrated as a computer-implemented or computer-based platform. Another example platform for wireless terminal 70 (5) may be that of a hardware circuit, for example, an application-specific integrated circuit (ASIC) in which the circuit elements are structured and operated to carry out the various actions described in this document. .
    [0076] As will be recognized by those skilled in the art, the innovative concepts described in this application can be modified and varied over a wide variety of applications. Consequently, the scope of the patented object should not be limited to any of the specific exemplary teachings discussed above, but is instead defined by the following claims.
