    TECHNOLOGICAL FIELD
    [001] Embodiments of the present invention generally relate to measurement data collected during an idle state and, in one embodiment, to methods and apparatus for reporting the measurement data in an idle mode. FUNDAMENTALS
    [002] In a cellular or wireless network, information regarding radio coverage is instructive for purposes of optimizing coverage. In this regard, information regarding radio coverage can be useful for network planning, network optimization, radio resource management parameter optimization and other purposes. Having this information, radio coverage can be improved which, in turn, can have a significant impact on the service that can be provided to customers in a particular region.
    [003] To determine the coverage provided by a radio network, field tests were conducted to collect information about radio coverage. Field tests may be conducted on a periodic basis and/or in response to certain events. For example, field tests can be conducted, along with the deployment of a new base station. In this regard, field tests can be carried out before or after service activation of a new base station. Field tests can collect a variety of measurement data including radio environment measurements such as downlink pilot measurements, transmit main power room measurements, measurements associated with a random access failure, measurements associated with a paging channel failure and measurements associated with a broadcast channel failure. Based on the measurement data, the initial area tuning can be performed, by selecting an appropriate antenna for the new cell, the adjustment of the antenna having a slope of the new base station and neighboring base stations, the adjustment of base station transmission power and the like. Following the development of a new base station, additional field tests can be carried out with the resulting measurement data collected by these additional field tests being used to provide additional area tuning.
    [004] Field tests can also be conducted before and/or after the construction of a new highway, railroad or major construction, as such construction projects generally represent regions that will experience an increase in population, which further encourages the provision of improved coverage. Additionally, large construction projects can also create new sources of shading losses and may need to be addressed to ensure adequate coverage, such as by deploying new base stations, adjusting the antenna tilt of existing base stations or similar. Field tests may also be conducted in response to complaints or other issues raised by customers that indicate yield and/or coverage concerns.
    [005] The measurement data collected during field tests can not only be used to effect coverage optimization, but can also be used for a number of other purposes. For example, measurement data collected during field tests can be used, for mobility optimization, capacity optimization, parameterization for common channels, quality of service verification and the like.
    [006] For network operators, however, manual field tests can disadvantageously cause significant operating costs. For example, field testing may be personnel intensive in the network operation and the tests may be repeated whenever there are changes in network topology or configuration. BRIEF SUMMARY

    [022] Some embodiments of the present invention will now be more fully described below in the present document, with respect to the accompanying drawings, in which some, but not all of the embodiments of the invention are shown. Indeed, the invention may be incorporated in many different ways and should not be construed as limited to the embodiments shown herein; instead, these modalities are provided, so this description will satisfy the applicable legal needs. As reference numbers refer to elements throughout the document.
    [023] As used herein, the term "circuit set" refers to (a) hardware-only circuit implementations (eg, analog and/or digital circuit set implementations); (b) combinations of circuit and computer program product(s) which comprise(s) software and/or firmware instructions stored in one or more computer readable memories that work together to cause an apparatus to perform one or more functions described in this document; and (c) circuitry, such as, for example, a microprocessor(s) or a portion of a microprocessor(s), which requires software or firmware for operation even if the software or firmware is not physically present. This definition of 'circuit set' applies to all uses of this term herein, including any claims. As a further example, as used herein, the term 'circuit set' also includes an implementation which comprises one or more processors and/or portion(s) thereof and attached software and/or firmware. As another example, the term 'circuit set' as used herein also includes, for example, a baseband integrated circuit or application processor integrated circuit for a mobile phone or a similar integrated circuit in a server, a cellular network device, other network device, and/or other computer device.
    [024] Figure 1 illustrates a block diagram of a system 100 to facilitate the collection and reporting of measurement data according to an exemplary embodiment of the present invention. As used herein, "exemplary" merely means an example and as such represents an exemplary embodiment of the invention and is not to be construed as limiting the scope or spirit of the invention in any way. It will be appreciated that the scope of the invention encompasses many potential embodiments beyond those illustrated and described herein. As such, while Figure 1 illustrates an example configuration of a system to facilitate the collection and reporting of measurement data, numerous other configurations can also be used to implement embodiments of the present invention. Additionally, while the system is described as collecting measurement data that is consistent with those collected in conjunction with field tests, other types of measurement data may be collected for other purposes, in accordance with other embodiments of the present invention, as well as or rather than measurement data that is collected to replace or at least reduce field testing. In at least some modalities, the system. 100 includes one or more terminal apparatus 102 and one or more network nodes 104. In at least some embodiments, system 100 further comprises a network 108. Network 108 may comprise one or more wire networks, one or more networks of yarn, or some combination thereof. In one embodiment, the network 108 comprises a public location mobile network (e.g., a cellular network), which may be implemented by a network operator (e.g., a cellular access provider). The network 108 can operate in accordance with universal terrestrial radio access network (UTRAN) standards, UTRAN (E-UTRAN) developed standards, GSM (Global System for mobile communication) EDGE (GSM Enhanced Data Environment) network standard access radio (GERAN) and/or similar. It will be appreciated, however, that where references are made herein to a network standard and/or particular terminology for a network standard, the references are provided merely by way of example and not by way of limitation.
    [025] The network node 104 can comprise any network entity configured to communicate with the terminal apparatus, with respect to the collection and reporting of measurement data. In this regard, the network node 104 may comprise, for example, a base station (BS) as an eNode B (eNB) according to the E-UTRAN standard. As such, in some embodiments, network node 104 is configured to provide access to network 108 to terminal apparatus 102.

While the network node 106 that is configured to process and analyze the measurement data can also serve as a network node 104 that communicates with the terminal apparatus 102, the network node 106 of a mode that is configured to process and analyze the measurement data can be a network node, such as a server or other computer device, in the network management system (NMS).
    [027] To reduce reliance on manual field testing and to correspondingly reduce associated operating costs, a terminal apparatus 102 can be used, in accordance with exemplary embodiments of the present invention to collect and report measurement data while, otherwise implemented for normal use. The measurement data can be collected by one or more nodes of network 104 for processing and analysis, as an alternative way, to discover potential problems, if any, in network 108, such as problems related to coverage or capacity, problems related to the settings of various network parameters and the like. Thus, the exemplary embodiments of the present invention support the terminal apparatus 102 in its collection and reporting of measurement data to the network 108, so that the network operator can replace the measurement data collected by the terminal apparatus with at least part of the measurement data otherwise collected by manual field testing. As described below, terminal apparatus 102 can be configured to take measurements during idle mode with the resulting measurement data then being reported to network node 104 in an effective and efficient manner.

    [040] The interaction of the network node 104 and the terminal apparatus 102, according to an embodiment of the present invention is shown in Figure 4. In this regard, the operations performed by the network node 104 are shown on the left side of Figure 4, while the operations performed by the terminal apparatus 102 are shown on the right side of Figure 4. As shown in block 200 of Figure 4, the network node 104 is configured to transmit measurement configuration information via a broadcast channel to the apparatus. terminal 102 while the terminal device is in an idle mode. In addition to the measurement configuration information, the network node 104 may also be configured to transmit the configuration information report over the broadcast channel to the terminal apparatus 102 while the terminal apparatus is in an idle mode. For example, network node 104 may include means, such as communication interface 124 and/or processor 120, for causing measurement configuration information and/or reporting configuration information to be transmitted.
    [041] In one embodiment, the network node 104 is configured to transmit the measurement configuration information as the system information via a broadcast channel. In conjunction with the E-UTRAN standard, for example, the network node, for example, eNB, can be configured to transmit measurement configuration and/or reporting configuration information in one or more blocks of system information. In this regard, the network node may include the measurement configuration information and/or the report configuration information as new information, elements in an existing information system block or a new information system block may be created to load the measurement setup information and/or the report setup information. At times when a new system information block is created, the priority and periodicity of the new system information block can be set such that reception of the new system information block by terminal apparatus 102 while in the non-active phase does not it will adversely impact other activities performed by the terminal device while in the inert phase.
    [042] The network node 104 may be prompted to transmit measurement configuration information on the determination that a terminal apparatus 102 has entered an idle mode, as indicated by the information exchanged between a network node and the terminal apparatus along with the terminal device input in idle mode. Alternatively, the network node 104 can be configured to transmit the measurement configuration information on a periodic basis to each terminal apparatus 102 that is in an idle mode at the time of reporting the measurement configuration information. Still further, the network node 104 can be configured to transmit the measurement configuration information according to other schedules or in response to other actions.
    [043] The network node 104 can provide several types of measurement configuration information which includes one or more of the following: the quantity of the terminal device 102 should be measured, the quantities that the terminal device should include in a report , the length of the period over which the terminal device must make measurements, states of the terminal device in which the measurements are valid, and the geographic areas in which the terminal device must make the measurements, such as the area supported by the network node or similar .
    [044] In response, the terminal apparatus 102 is configured to receive the measurement setup information and/or the reporting setup information through the broadcast channel during idle mode, as shown in operation 202 of Figure 4. For example , terminal apparatus 102 may include means such as antenna 12, receiver 16 and/or processor 20 for receiving measurement setup information and/or reporting setup information. The terminal apparatus 102 can then take one or more measurements during idle mode in accordance with the measurement setup information that has been received. See operation 204 of Figure 4. In this regard, terminal apparatus 102 may include means, such as processor 20, configured to cause one or more measurements to be taken while in idle mode based on measurement configuration information. Terminal apparatus 102 and, in one embodiment, terminal apparatus processor 20, may be configured to take a variety of measurements. In one embodiment, the terminal apparatus 102 is configured to cause a variety of measurements related to the radio environment including, for example, downlink pilot measurements, such as a common pilot channel (CPICH) and received signal code energy (RSCP). ), CPICH Ec/No, Duplex Time Division (TDD) Primary Common Control Physical Channel (P-CCPCH) RSCP and Interference Signal Code Energy (ISCP), Received Reference Signal Energy (RSRP) and Received Quality of reference signal (RSRQ) on a periodic basis, at times when the performance of the network node 104, for example, the service base station becomes worse than a pre-defined threshold. In addition to the measurement data, the terminal apparatus 102, such as the processor 20 and/or an associated positioning sensor, can also determine the location of the terminal apparatus at the time of a measurement, the time when it takes place and/or the cell identification of network node 104, e.g., the serving base station, at the time the measurement was made. This additional data can be associated with the measurement data to provide additional explanations and/or context for the measurement data.
    [045] Additionally, terminal apparatus 102, as, in one embodiment, processor 20, may take measurements of the radio environment (including, for example, those noted above) at other times, such as in the event of a random access failure , a paging channel failure and/or a broadcast channel failure. At times when measurements occur as a result of the paging channel failure, the terminal apparatus 102 may notice that it has failed to decode the paging control channel (PCCH) consecutively by a predefined number, eg X1, of times even the terminal apparatus has managed to decode the physical downlink control channel (PDCCH) in its paging occasion. At this time, the terminal apparatus 102, like the processor 20, can be configured to measure the average RSRP and RSRQ over the time of the first PCCH decoding failure of the decoding failure of the X1th PCCH. Along with these measurements of the radio environment, the terminal apparatus 102, such as the processor 20, can also be configured to determine the location associated with each failed attempt to decode the PCCH, the time when the X1th PCCH decoding failure occurred and the identity of the base station when the PCCH decoding failure occurred. With respect to measurement data collected in response to a broadcast channel failure, the terminal apparatus 102, like the processor 20, can determine the average RSRP and RSRQ over time when the physical broadcast channel (P-BCH), PDCCH or downlink synchronization channel (DL-SCH) cannot be decoded. In addition to measurement data, terminal apparatus 102, such as processor 20, may also be configured to determine the type of broadcast channel where the failure occurred, the location where the decoding failure occurred, the time when the failure occurred. decoding occurred, the identity of the base station when the decoding failure occurred, and the base carrier frequency when the decoding failure occurred.
    [046] While in idle mode, terminal apparatus 102, like processor 20, may continue to take measurements, as on a periodic basis and/or in response to predefined events described above. Therefore, as indicated by operation 206 of Figure 4, terminal apparatus 102 can return to active mode and can communicate with network node 104 via signaling channels to arm a connection. In one embodiment, terminal apparatus 102, like processor 20, can provide an indication to network node 104 as to whether or not measurement data has been collected and is available from the period of time the terminal apparatus was in the idle mode. See operation 208 of Figure 4. For example, terminal apparatus 102 may include means, such as processor 20, to cause indication of the availability of measurement data to be provided. In this regard, terminal apparatus 102 may provide the indication as part of the arming procedure during transition to active mode or following an active mode resolution. In one embodiment, terminal apparatus 102, such as processor 20, may be configured to provide a single bit having a state indicative of the availability of measurement data and another state indicative of the lack of any measurement data. Additionally, a terminal apparatus 102, such as processor 20, of one mode may also provide additional information, with respect to the measurement data, such as an indication regarding the amount of measurement data, to assist the network node 104 in planning for retrieval of measurement data. As indicated by the dotted lines over block 208 in Figure 4 and as described below, terminal apparatus 102 of other embodiments need not provide an indication to network node 104 regarding the availability of the measurement data and, instead, the node The network may require the measurement data, if any, of a terminal device that enters active mode as a result, for example, of knowledge by the network node that the terminal device in the network node's coverage area has been previously configured to collect measurement data while in idle mode.
    [047] As indicated, by operation 210, the network node 104 of this mode receives the indication of the availability of measurement data from the terminal apparatus 102. For example, the network node 104 may include means such as the interface of communication 124 and/or the processor 120 to receive the indication of whether or not the measurement data is available. At times when the terminal apparatus 102 provides additional information regarding the measurement data, such as an indication of the quantity of the measurement data, the network node 104, such as the communication interface 124 and/or the processor 120, may also receive this additional information. The network node 104 can then determine whether measurement data is available and, if so, can make a request to the terminal apparatus 104 for a report of the measurement data. See operation 212 of Figure 4. For example, network node 104 may include means, such as processor 120 and/or communication interface 124, to cause a request to be made for a report of the measurement data. As the network node 104 is directed to the provision of the measurement data by the terminal apparatus 102, the network node can control the delivery time of the measurement data. In this regard, the network node 104 can be configured to make the request to the terminal apparatus 102 so that measurement data is provided, for example, during a period of relatively low network usage 108, so as not to increase network load at times when the network is most loaded. In other embodiments, the network node 104 may be configured to request measurement data in response to one or more predefined triggers, such as a trigger based on a preset time, based on a preset period, based on the demand, based on the location of the terminal device 102, based on the amount of memory used, by the terminal device for storing the measurement data (as can be determined, for example, based on the indication of the quantity of measurement data) and on times when the terminal apparatus is terminating its log record measurement data, such as being delivered to another base station or the like.
    [048] Additionally, the network node 104 may regard additional information provided by the terminal apparatus 102 together with the measurement data as information regarding the amount of measurement data. Thus, at times when the measurement data is of relatively large quantity, the network node 104 can only request delivery of the report of the measurement data at times when the utilization of the network 108 is relatively low. Alternatively, at times when the amount of measurement data is relatively small, the network node 104 can similarly not be decremented and can make a request for a report of the measurement data independent of the use of the network 108.
    [049] The terminal apparatus 102 may be configured to receive a request for a report of the measurement data and, in response, provide a report of the measurement data as indicated by operations 214 and 216 of Figure 4. In this regard, the terminal apparatus 102 may include means, such as antenna 12, receiver 16 and/or processor 20, for receiving the request to provide a report of the measurement data and means, such as processor 20, for making a report of the measurement data. to be provided. At times when the request for measurement data provided by the network node 104 defines the conditions under which the report is to be made, such as the period of time during which the report is to be made or the like, the terminal apparatus 102 may also be configured to recognize these conditions and to report the measurement data in confirmation with these conditions. The network node 104, in turn, is configured to receive the measurement data report. See operation 218 of Figure 4. In this regard, network node 104 may include means, such as communication interface 124 and/or processor 120, for receiving the measurement data report.
    [050] The measurement data can then be analyzed, typically in conjunction with the measurement data provided by a number of other terminal apparatus 102, to determine the coverage provided by the network node 104, such as a base station. If appropriate, the coverage provided by network node 104, as a base station, can be adjusted, such as employing additional base stations, adjusting antenna tilt of existing base stations, adjusting base station transmit power or similar. By collecting measurement data with terminal device 102 in idle mode, however, the reliance on field tests to collect the measurement data can be reduced. In this way, the operating costs associated with field tests and the resulting environmental impact caused by field tests can be advantageously reduced. Furthermore, by allowing the network node 104 of a mode to provide the measurement configuration information to the terminal apparatus 102, the network node can control the type of measurement data that is collected. Additionally, by merely having the terminal apparatus 102 of a mode provide an indication regarding the availability of the measurement data upon its return to active mode, the network node 104 can determine an appropriate time at which the request delivery of the data measurement through taking into account, for example, network conditions. Additionally, by allowing the network node 104 of a modality to provide the measurement configuration information and direct reporting of the results of the measurement data, the logic that must be implemented by the terminal apparatus 102 can be simplified with less confidence in the drives implemented by the terminal device or similar.
    [051] While the network node 104 can process and analyze the measurement data, the system 100 of an example embodiment may include another network node 106. In this embodiment, the network nodes 104 that directly interact with the terminal apparatus 102 can be configured to supply the measurement data that is collected from the terminal apparatus to the network node 106. The network node 106 can, in turn, be configured to process and analyze the measurement data of one or more network nodes 104 on a more centralized basis through the analysis provided by network node 106 in this modality, system-wide problems can be identified as a result of their centralized placement in system 100.
    [052] The operations described above in conjunction with Figure 4 can be varied in other modalities while still collecting measurement data during idle mode and then reporting the measurement data under the direction of network node 104. For example, the apparatus terminal 102 can be configured so that no indication is provided by returning to active mode and whether or not measurement data has been collected. In this mode, the network node 104 can be configured to request a report of measurement data from each terminal apparatus 102 that communicates with the network node to enter an active mode. For example, the report request can also be sent only to selected endpoint 102 to avoid, for example, excessive traffic load due to report measurement. According to this modality, some terminal apparatus 102 may have collected measurement data while in idle mode and may therefore be able to provide a report of the measurement data to network node 104, while another terminal apparatus may not have collected the data. while in idle mode and as a result may not provide a report of the measurement data to the network node.
