    Priority Claim under 35 U.S.C. § 119
    [0001] The present application claims priority from provisional application No. 61/285,810 entitled "Network-Initiated Attached and Registration-Less Paging" filed December 11, 2009, and assigned to the assignee of the present application and expressly incorporated herein by reference. Field
    [0002] This description generally refers to equipment and methods for registering to a wireless communication system. More particularly, the description refers to network-initiated attaching and paging for mobile devices that are not currently registered to a radio network. Fundamentals
    [0003] A wireless network can carry a variety of communication sessions with widely different characteristics. For example, a characteristic is the duty cycle which is the percentage of time a mobile terminal is actually transmitting or receiving information. In many cases, mobile terminals can have a low duty cycle if the amount of data to be communicated over an extended period of time is too low.
    [0004] When a large number of mobile terminals on a wireless network want to connect, each with very low data traffic, network congestion can result. In one example, connections can be requested for an extended period of time. For example, network congestion can be expensive or difficult due to maintaining a large number of connections. For example, very low duty cycles on mobile terminals may be necessary to achieve long battery life. summary

    [0027] The detailed description given below in relation to the accompanying drawings is intended to serve as a description of various aspects of the present description and is not to represent the only aspects in which the present description may be practiced. Each aspect described in that description is provided merely as an example or illustration of the present description, and is not necessarily to be considered preferred or advantageous over other aspects. The detailed description includes specific details for the purpose of providing a thorough understanding of this description. However, it will be apparent to those skilled in the art that the present description can be practiced without these specific details. In some cases, well-known structures and devices are illustrated in block diagram form in order to avoid obscuring the concepts of the present description. Acronyms and other descriptive terminology may be used merely for the sake of convenience and clarity and should not limit the scope of the present invention.
    [0028] While for the sake of simplicity of explanation, the methodologies are illustrated and described as a series of acts, it should be understood and appreciated that the methodologies are not limited by the order of the acts, as some of the acts may, accordingly with one or more aspects, occur in different orders and/or simultaneously with other acts from what has been illustrated and described here. For example, those skilled in the art will understand and appreciate that a methodology may alternatively be represented as a series of interrelated states or events, such as in a state diagram. Furthermore, not all illustrated acts may be necessary to implement a methodology according to one or more aspects.
    [0029] The techniques described here can be used for various wireless communication networks, such as Code Division Multiple Access (CDMA) networks, Time Division Multiple Access (TDMA) networks, Division Multiple Access networks Frequency Control (FDMA), Orthogonal FDMA networks (OFDMA), Single Carrier FDMA networks (SC-FDMA), etc. The terms “networks” and “systems” are often used interchangeably. A CDMA network may implement a radio technology such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes broadband CDMA (W-CDMA), and low chip rate (LCR). Cdma2000 covers IS-2000, IS-95 and IS-856 standards. A TDMA network can implement a radio technology such as a Global System for Mobile Communications (GSM). an OFDMA network can implement a radio technology such as Evolved UTRA (E-UTRA), IEEE-802.11, IEEE 802.16, IEEE 802.20, Flash-OFDM®, etc. UTRA, E-UTRA and GSM are part of the Universal Mobile Telecommunications System (UMTS). Long Term Evolution (LTE) is a future version of UMTS that uses E-UTRA. UTRA, E-UTRA, GSM, UMTS and LTE are described in documents from an organization called the “3rd Partnership Project. Generation” (3GPP). cdma2000 is described in documents from an organization called “Partnership Project 3rd. Generation 2” (3GPP2). These various radio technologies and standards are known in the art.
    [0030] Figure 1 is a block diagram illustrating an example of an access node/UE system 100. Those skilled in the art will understand that the illustrative access node/UE system 100 illustrated in Figure 1 can be implemented in a FDMA environment, an OFDMA environment, a CDMA environment, a WCDMA environment, a TDMA environment, a spatial division multiple access (SDMA) environment, or any other suitable wireless environment.
    [0031] The access node/UE system 100 includes an access node 101 (e.g. base station) and a user equipment or UE 201 (e.g. wireless communication device or mobile station). In the downlink extension, the access node 101 (e.g., base station) includes a data processor (TX) A 110 that accepts, formats, encodes, interleaves and modulates (or symbol maps) traffic data and provides traffic symbols. modulation (eg data symbols). The TX data processor A 110 is in communication with an A symbol modulator 120. The A symbol modulator 120 accepts and processes the data symbols and downlink pilot symbols and provides a sequence of symbols. In one aspect, symbol modulator A 120 is in communication with processor A 180 which provides configuration information. Symbol modulator 120 multiplexes the data symbols and downlink pilot symbols and supplies them to transmitter unit A 130.
    [0032] Each symbol to be transmitted can be a data symbol, a downlink pilot symbol or a signal value equal to zero. Downlink pilot symbols can be sent continuously in each symbol period. In one aspect, the downlink pilot symbols are frequency division multiplexed (FDM). In another aspect, the downlink pilot symbols are orthogonal frequency division multiplexed (OFDM). In another aspect, the transmitter unit A 130 receives and converts the symbol sequence into one or more analog signals and further conditions, for example, amplifies, filters and/or frequency upconverts the analog signals to generate an analog downlink signal. Suitable for wireless transmission. The analogue downlink signal is then transmitted through antenna 140.
    [0033] In the downlink, the UE 201 includes the antenna 210 for receiving the analog downlink signal and recording the analog downlink signal at a receiver unit (RCVR) B 220. In one aspect, the receiver unit B 220 conditions, by For example, it filters, amplifies, and frequency downconverts the analog downlink signal to a first “conditioned” signal. The first “conditioned” signal is then sampled. Receiver unit B 220 is in communication with a symbol B demodulator 230. Symbol B demodulator 230 demodulates the first "conditioned" and "sampled" signal (e.g., data symbols) sent from receiver unit B 220. Those skilled in the art will understand that an alternative is to implement the sampling process in symbol demodulator B 230. Symbol demodulator b 230 is in communication with a processor B 240. Processor B 240 receives downlink pilot symbols from the symbol demodulator B 230 and performs channel estimation on downlink pilot symbols. In one aspect, channel estimation is the process of characterizing the current propagation environment. Symbol demodulator B 230 receives a frequency response estimate for the downlink extension from processor B 240. Symbol demodulator B 230 performs data demodulation on the data symbols to obtain data symbol estimates in the path of downlink. Downlink path data symbol estimates are estimates of data symbols that have been transmitted. Symbol demodulator B 230 is also in communication with an RX B 250 data processor.
    [0034] The RX B data processor 250 receives the data symbol estimates in the downlink path from the B symbol demodulator 230 and, for example, demodulates (i.e., de-maps to symbol), interleaves and/or decodes the Data symbol estimates on the downlink path to retrieve the traffic data. In one aspect, processing by symbol demodulator B 230 and RX data processor B 250 is complementary to processing by symbol modulator A 120 and TX data processor A 110, respectively.
    [0035] In the uplink extension, the UE 201 includes a TX B 260 data processor. The TX B 260 data processor accepts and processes the traffic data to send data symbols. The TX B 260 data processor is in communication with a 270 D symbol modulator. The 270 D symbol modulator accepts and multiplexes the data symbols with uplink pilot symbols, performs modulation, and provides a symbol sequence. In one aspect, the D symbol modulator 270 is in communication with the B processor 240 which provides communication information. The D 270 symbol modulator is in communication with a B 280 transmitter unit.
    [0036] Each symbol to be transmitted can be a data symbol, an uplink pilot symbol or a signal value equal to zero. Uplink pilot symbols can be sent continuously in each symbol period. In one aspect, uplink pilot symbols are FDM. In another aspect, the uplink pilot symbols are OFDM. In another aspect, the uplink pilot symbols are CDM. In one aspect, the transmitter unit B 280 receives and converts the symbol sequence into one or more analog signals and further conditions, for example, amplifies, filters and/or frequency upconverts the analog signals to generate an analog uplink signal Suitable for wireless transmission. The analog uplink signal is then transmitted through antenna 210.
    [0037] The analogue uplink signal from the UE 201 is received by the antenna 140 and processed by a receiver unit A 150 to obtain samples. In one aspect, the receiver unit A 150 conditions, for example, filters, amplifies and frequency downconverts the analog uplink signal to a second “conditioned” signal. The second “conditioned” signal is then sampled. Receiver unit A 150 is in communication with a C 160 symbol demodulator. Those skilled in the art will understand that an alternative is to implement the sampling process in the C 160 symbol demodulator. The C 160 symbol demodulator performs data demodulation in the data symbols for obtaining data symbol estimates on the uplink path and then provides the uplink pilot symbols and data symbol estimates on the uplink path to the RX A 170 data processor. uplink paths are estimates of data symbols that have been transmitted. RX data processor A 170 processes data symbol estimates on the uplink path to retrieve traffic data transmitted by wireless communication device 201. Symbol demodulator C 160 is also in communication with processor A 180. A 180 processor performs channel estimation for each active terminal transmitting on the uplink extension. In one aspect, multiple terminals may transmit pilot symbols simultaneously on the uplink extension on their respective designated sets of pilot subbands where the sets of pilot subbands may be intertwined.
    [0038] Processor A 180 and processor B 240 direct (i.e., control, coordinate or manage, etc.) the operation in the access node 101 (e.g., base station) and in the UE 201, respectively. In one aspect, one or both of processor A 180 and processor B 240 are associated with one or more memory units (not shown) for storing program codes and/or data. In one aspect, one or both of processor A 180 and processor B 240 perform computations to derive pulse and frequency response estimates for the uplink span and downlink span, respectively.
    [0039] In one aspect, the UE/Access Node System 100 is a multiple access system. For a multiple access system (e.g. FDMA, OFDMA, CDMA, TDMA, SDMA, etc.), multiple terminals transmit simultaneously on the uplink span, allowing access to a plurality of UEs. In one aspect, for the multiple access system, pilot subbands can be shared between different terminals. Channel estimation techniques are used in cases where the pilot subbands for each terminal span the entire operating band (possibly except for the band edges). Such a pilot subband structure is desirable to obtain frequency diversity for each terminal.
    [0040] Figure 2 illustrates an example of a wireless communication system 290 that supports a plurality of users. In Figure 2, reference numerals 292a to 292g refer to cells, reference numerals 298a to 298g refer to base stations (BS) or base transceiver station (BTS) and reference numerals 296a to 296j refer to access UEs . Access size may vary. Any of a variety of algorithms and methods can be used to schedule transmissions into system 290. System 290 provides communication for a number of cells 292a to 292g, each of which is served by a corresponding base station 298a to 298g, respectively. .
    [0041] In one aspect, the present description proposes a technique by which a very large number of mobile terminals, also known as mobile devices, can be attached to a wireless network in a network-initiated manner. In one example, mobile devices maintain very low duty cycle traffic and are basically stationary. In one aspect, rather than being attached to the wireless network over a long period of time, a technique described in this description employs a single attachment step, establishing a long-term identifier (LTID) for the mobile device, and the storage of the coverage area, or set of sectors, in which the mobile device is located. Subsequently, the mobile device can completely detach itself from the wireless network and start listening to the paging indicators that are positioned on the time slices, or moments, which are a function of the LTID.
    [0042] The present description describes a process to initiate the attachment of a mobile device from the wireless network side. Also described is a mechanism for paging mobile devices that are currently not registered to a radio access network or a core network of a wireless network. One potential advantage is that a large number of very low duty cycle mobile devices can be connected to a wireless network whenever the wireless network detects a need for data transfer between the mobile device and the wireless network.
    [0043] In one example, for some applications using machine-to-machine (M2M) communications it is expected that a very large number of mobile devices may need to be connected to the wireless network with each mobile device generating data traffic with one duty cycle very low. Those skilled in the art will understand that an example of an M2M device is a mobile device. In one aspect, mobile devices used for M2M applications are known as M2M devices. Examples of such applications include smart meters, monitoring and security systems, smart vending machines, eHealth for disease management, remote monitoring of industrial machines or facilities, or M2M applications that rely on battery powered mobile devices without frequent recharging. If a large number of such M2M devices need to remain connected, for example, attached once to the wireless network and remain attached, for extended periods of time, it can also be very expensive or even impossible in wireless systems due to the large number of connections (ie attached mobile devices) that need to be maintained. Additionally, the mobile device, or M2M device, may need to operate at an extremely low duty cycle to ensure long battery life.
    [0044] In one aspect, for such applications it may be desirable to have a mechanism by which the wireless network itself can initiate an attachment of a specific M2M device or a group of M2M devices when there is a need to exchange information with the addressed M2M device or M2M device group. Whenever an M2M application running on the wireless network side or an M2M application running on an M2M device needs to communicate with another M2M device or a group of M2M devices, the wireless network can then initiate an attachment of the requested M2M devices without the need to stay connected at all times.
    [0045] In one aspect, to minimize the impact of maintaining context information on the wireless network and performing the periodic procedures necessary for keeping the record on the wireless network, a wireless-initiated attachment procedure can work with the M2M devices that are not registered to the wireless network. Therefore, in one example, a registrationless paging method would allow efficient use of wireless-initiated pinning procedures.
    [0046] In one aspect, if a very large number of M2M devices with very low duty cycles require service while they are stationary or remaining in the same coverage area (that is, remain in the coverage area of the same cell or a set of cells ), it can be difficult to keep all M2M devices registered at all times. For example, potential traffic jams may include one or more of the following:
    [0047] Consumption of storage & processing resources on the wireless network: In one example, being registered implies that certain context information must be stored and maintained on the wireless network which may not be acceptable depending on the number of devices developed. If a very large number of such M2M devices exist, there can be significant complexity and cost to maintaining all the information within the wireless network and ensuring that the information is sufficiently up-to-date.
    [0048] Consumption of radio resources: In another example, if a very large number of M2M devices are registered on the wireless network, significant radio resources can be consumed even when no information needs to be transferred between them and the wireless network . For example, potential issues might include the need to report to neighboring cells or report events that may need to be configured on a wireless network, periodic updates of location or log areas, etc.
    [0049] Processing/battery resource consumption on device: In another example, existing procedures for registered M2M devices may cause an impractical resource consumption (eg battery power consumption) within the M2M device that can be avoided by paging without registration. A registered M2M device may be restricted to perform certain periodic tasks such as listening to possible pages or reporting periodic measurements or events with a maximum period that may not be possible for some M2M applications.
    [0050] In one aspect, a way to serve many low duty cycle M2M devices performs some form of a low duty cycle recording procedure, which may, in an example, follow one or more of the following steps: Perform a regular access procedure; Register on the network (for example, attach); Establish a data connection (eg, packet data protocol (PDP) context); Search the server (or service layer) that may have data for the M2M device; If nothing needs to be done, disconnect the connection; Unregister with the network; Enter the latent state and redo the procedure later.
    [0051] In one example, a low duty cycle registration procedure can have negative impacts. From the wireless side, negative impacts can result if many M2M devices are performing the low duty cycle registration procedure which results in relatively large overhead for the actual registration procedure compared to the search step . For example, the processing required for registration on the wireless side may be much higher than the actual processing for server lookup. For example, if the M2M device just wants to ask the server “Is there something for me ”, the server should simply answer “yes” or “no”. This example results in a small amount of information compared to what is transferred and processed for a complete record, setting up a connection, etc.
    [0052] Furthermore, if the search results in a low demand for real data transfer, there can be a great waste of resources. In one example, the polling interval can be scaled to be significantly shorter than the expected time between events that would trigger the need for data transfer. For example, it can be assumed that less than half of the searches can actually result in some data exchange. If a very large number of M2M devices perform this type of low task cycle registration procedure, a large waste of capacity can result.
    [0053] On the device side, the device may need to perform expensive procedures, such as attaching, even when there is no data traffic. In this case, the battery impact for each of the attach cycles would be much more significant than proper paging.
    [0054] With respect to the Research Entity, if there is not a single server or a central service layer to determine if there is a need for action (for example, transfer of information), it can be difficult to determine which location is the point correct to be searched. For example, there may be multiple potential entities that an M2M device may need to poll in case it goes through the periodic low duty cycle record.
    [0055] With the potential negative impacts, a periodic low duty cycle record and polling procedure does not solve the service problem of many low duty cycle M2M devices on a wireless network.
    [0056] In one aspect, to minimize the M2M device context that needs to be maintained on the wireless network and at the same time allow very long paging cycles without the need for M2M devices to be registered, a solution to this need might include a wireless-initiated attach procedure associated with a recordless paging.
    [0057] In one aspect, unregistered paging refers to paging from a mobile terminal, eg M2M device, which is not registered to a wireless network. For example, no wireless network registration results in the wireless network not having any context information about the mobile terminal. The context information can be location information about the mobile terminal, which can be used to find the mobile terminal as needed for paging. In another aspect, an external user, for example an Internet-connected server application or a middleware platform, can request a page from a wireless terminal in a specific area. Paging without registration of the mobile terminal may include a pre-defined rule for a listen time when the mobile terminal must listen to such paging requests. In one example, the mobile terminal wakes up at the time of listening to receive the paging request.
    [0058] Figure 3 illustrates an example of a high-level M2M architecture with multiple M2M devices attached. In one aspect, a high-level M2M architecture uses an M2M service layer on the wireless side to communicate with a core network of a wireless system as illustrated in figure 3. A number of M2M applications (illustrated above in figure 3) communicates with an M2M service layer (illustrated as a box below the M2M applications) to provide functionality for exchanging information with the M2M devices (illustrated at the bottom of Figure 3). In one example, if M2M devices use a wireless wide area network (WWAN) to connect the M2M service layer, the M2M devices can use the available radio access technology of the WWAN to communicate. For a wireless-initiated attach procedure in this context, an M2M application that sits on top of the M2M service layer or an M2M application running on one of the M2M devices can request the M2M service layer to establish an exchange of information between the M2M app requesting and a specific M2M device or a group of M2M devices.
    [0059] In one aspect, the M2M device layer can contact the core network of the underlying wireless network, eg WWAN, to connect the addressed M2M device. For example, if the M2M device is not currently attached to the network, it would establish the attachment. For example, if the addressed M2M device is not registered with the WWAN, it can use a paging mechanism to obtain the requested M2M device.
    [0060] In one example, the wireless-initiated attach procedure can be triggered by a special message from the M2M service layer on the wireless-network side or by a normal Domain Name System (DNS) lookup. In one aspect, the wireless network does not have the normal context information for the M2M device that is addressed by the M2M service layer and therefore a special paging message can be introduced. In one example, the wireless-initiated attach procedure might operate as follows:
    [0061] The attachment request of an M2M device arrives at a paging agent on the core network side (for example, serving the GPRS support node/Mobility Management Entity (SGSN/MME)) through a service layer M2M or through the DNS system.
    [0062] The paging agent generates a paging message that is similar to the paging messages used in WWANs, but includes a long-term ID that is not allocated by the wireless network itself (for example, fully qualified domain name ( FQDN) or a long-term ID (LTID) that was established during a first contact between the M2M device and the service layer).
    [0063] The M2M device knows through an agreed rule how to determine the times at which it is supposed to listen to the paging indicators (in the existing paging channels or in new ones) as a function of FQDN or long-term ID.
    [0064] When the M2M device detects that it has been paged by the wireless network, it starts a normal attach procedure.
    [0065] In one aspect, the described approach allows for the reduction of context that needs to be maintained by the wireless network for an M2M device that is not registered with the wireless network to almost zero, in addition to the allocation of a fully qualified domain name (FQDN) or long-term identifier (LTID) plus the cell or group of cells in which paging needs to occur. Alternatively, for cases where registration to a wireless network, eg WWAN, is possible or necessary, the wireless-initiated attach procedure can also utilize existing paging mechanisms for devices that are already registered but not attached.
    [0066] In one aspect, the described approach contains a new paging mechanism that can be used to page M2M devices that are not currently registered to the wireless network, but for which a long term (LTID) has already been established. In one example, the approach described can be coupled with the flexibility to allow each very long paging cycle to allow for long battery life on the M2M device side.
    [0067] In one example, an unregistered paging procedure may include one or more of the following steps:
    [0068] Perform a normal registration, configure a connection to the M2M service layer; establish an identity (eg long term ID) to an M2M device.
    [0069] Indicate to the wireless network (that is, to the core network) that the M2M device that has just established its long-term ID with the M2M service layer is a special type that can use the new paging mechanism. And, the core network registers the cell or a set of cells that comprise the coverage area of the M2M device and maps that coverage area to the established long-term ID of the M2M device. In one aspect, this information is the small context that is maintained on the wireless network. In another example, it can also be defined that this context is kept static (ie not updated) until requested by the M2M device (eg when the M2M device is moved from one place to another).
    [0070] Disconnect connection and cancel registration.
    [0071] Use the M2M device's long term ID to determine the times when the M2M device listens to pages. The actual mechanism in the radio access network by which pages are sent can be either existing ones (ie use of existing paging channels including paging indicators) or new ones (different paging channels without any paging indicators or indicators many different).
    [0072] When the wireless network needs to page the M2M device, it uses the new paging occasions based on the long-term ID of the M2M device.
    [0073] When the M2M device detects a valid page for that M2M device during the newly defined paging occasions, it may receive some paging data (eg paging message) with that page. This paging data can be a short data packet from an M2M application (eg user data) can be special data to trigger further action. An option for special data, in one example, is sending a command to initiate a regular attach procedure from the M2M device side.
    [0074] In another aspect, the proposed solutions are also applicable to M2M systems that do not use an M2M service layer. The proposed solutions can also be used in M2M systems where an M2M server wants to reach an M2M device through a wireless network, for example, WWAN. In one example, the M2M server would only need to be able to send a request for a wireless-initiated attachment from the wireless core network. Additionally, in another example, the concept could also be extended to the initiation of attaching groups of M2M devices over a wireless network.
    [0075] Figure 4 illustrates a first example of a flowchart for paging without registration. In block 410, establishing a mobile device identity for an M2M device in a wireless network. At block 420, determining a time for the identified mobile device to listen to the pages. In block 430, the sending of a page from the wireless network to the identified mobile device during the given time. In one aspect, at block 440, the mobile device detects a valid page for the identified mobile device during the given time.
    [0076] Figure 5 illustrates a second example of a flowchart for paging without registration. At block 510, performing registration, setting up a connection, and establishing a mobile device identity for an M2M device in a wireless network. In one example, the connection is configured with an M2M service layer. In another example, the device identity for an M2M device (that is, M2M device identity) is a long-term ID (LTID). At block 520, indication that the identified mobile device can use a new paging mechanism. In one example, the referral is made to a core network within the wireless network. In block 530, disconnection of the connection and deregistration of the mobile device identified from the wireless network. In block 540, determination of a time when the identified mobile device should listen to the pages. In one example, more than one moment is determined. In one example, the determination uses the M2M device's LTID. In block 550, sending a page from the wireless network to the identified mobile device during the given time. In one example, the point in time is based on the LTID. In one aspect, at block 560, the mobile device detects a valid page for the identified mobile device during the given time. In one example, valid page detection also includes receiving paging data, such as user data or special data that triggers an additional action. For example, special data can be a command that initiates a regular attach procedure from the M2M device side.
    [0077] Figure 6 illustrates an example of a flowchart for a network-initiated attachment procedure. At block 610, a receipt of a request to attach a mobile device to a wireless network. In one example, the mobile device is an M2M device. In another example, the request arrives at a paging agent on one side of the core network. In another example, the request comes through an M2M service layer or through a domain name system (DNS) system. In another example, the paging agent is an SGSN GPRS or MME. In block 620, the generation of a paging message based on the request to secure the mobile device. In one example, the paging message includes an LTID. In another example, the LTID is not allocated by the wireless network itself. In another example, the LTID is allocated as an FQDN or an LTID that was established during a first contact between the mobile device and the service layer. In block 630, sending a paging indicia based on the paging message generated during a time based on an agreed rule. In one example, more than one paging indicator is sent. In one example, the agreed rule is based on FQDN or LTID. At block 640, accepting an attach procedure from the mobile device based on the paging indicator. In one example, the append procedure is triggered by the detection of paging indicators.
    [0078] Those skilled in the art will understand that the steps described in the illustrative flowcharts of figures 4, 5 and 6 can be interchangeable in their order without departing from the scope and spirit of this description.
