- the present disclosure proposes a technique by which a very large number of mobile terminals, also known as mobile devices, may be attached to a wireless network in a network initiated manner.
- the mobile devices maintain very low duty cycle traffic and are mostly stationary.
- a technique disclosed in the present disclosure employs a single attachment step, the establishment of 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 100007
- LTID long term identifier
- the present disclosure describes a process for initiating the attachment of a mobile device from the wireless network side. Also disclosed is a mechanism for paging of mobile devices that are currently not registered in a radio access network or a core network of a wireless network.
- a potential advantage is that a large number of very low duty cycle mobile devices may be connected to a wireless network whenever the wireless network detects a need for data transfer between the mobile device and the wireless network.
- M2M machine-to-machine
- M2M devices mobile devices used for M2M applications are known as M2M devices. Examples for such applications include smart meters, building monitoring and safety systems, smart vending machines, eHealth for disease management, remote monitoring of industrial machines or installations or M2M applications that rely on battery powered mobile devices without frequent recharging.
- M2M device may need to operate at an extremely low duty cycle to ensure a very long battery life.
- the wireless network itself could initiate an attachment of a specific M2M device or a group of M2M devices when there is need to exchange information with the addressed M2M device or group of M2M devices.
- a M2M application running on the wireless network side or a M2M application running on a M2M device needs to communicate with another M2M device or a group of M2M devices, the wireless network could then initiate an attachment of the requested M2M devices without need to stay connected all the time.
- a wireless network-initiated attachment procedure may work with M2M devices that are not registered in the wireless network. Therefore, in one example, a registration-less paging method would enable an efficient use of wireless network-initiated attachment procedures.
- possible bottlenecks may include one or more of the following:
- Radio resources In another example, if a very large number of M2M devices are registered in the wireless network, significant radio resources may be consumed even when no information needs to be transferred between them and the wireless network. For example, possible issues may include need for reporting of neighboring cells or reporting of events that might have to be configured in a wireless network, periodic updates of the location or registration areas, etc.
- one way of servicing many low duty cycle M2M devices performs some form of a low duty cycle registration procedure, which may, in one example, follow one or more of the following steps:
- PDP packet data protocol
- a low duty cycle registration procedure may have negative impacts. From a wireless network side, negative impacts may result if many M2M devices are performing the low duty cycle registration procedure which results in a fairly large overhead for the actual registration procedure compared to the polling step. For example, the processing required for the registration on the wireless network side may be much more than the actual processing for the polling of the server. For example, if the M2M device just wants to ask the server "Is there something for me?", the server should simply answer with a "yes" or "no". This example results in a small amount of information compared to what is transferred and processed for a full registration, setting up of a connection, etc.
- the polling interval may be dimensioned to be significantly shorter than the expected time between events that would trigger the need for data transfer. For example, it may be assumed that less than half of the polls may actually result in some data exchange. If a very large number of M2M devices perform this type of low duty cycle registration procedure, a large waste of capacity may result. 100007
- the device may need to perform expensive procedures, such as attach, 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 an appropriate paging.
- Entity to Poll if there is not a single server or a central service layer for determining whether there is a need for action (e.g., transfer of information), it may be difficult to determine which location is the right point to poll. For example, there may be multiple potential entities that a M2M device would have to poll in case it goes through periodic low duty cycle registration.
- one solution to this need may include a wireless network-initiated attach procedure associated with a registration-less paging.
- registration-less paging refers to paging a mobile terminal, e.g. M2M device, which is not registered in a wireless network.
- a mobile terminal e.g. M2M device
- Context information may be location information about the mobile terminal, which may be used to find the mobile terminal as needed for paging.
- an outside user for example a server 100007
- Registration-less paging of the mobile terminal may include a pre-defined rule for a listen time when the mobile terminal should listen to such paging requests.
- the mobile terminal wakes up at the listen time to receive the paging request.
- FIG 3 illustrates an example of a high level M2M architecture with several attached M2M devices.
- a high level M2M architecture uses a M2M service layer on the wireless network side to communicate with a core network of a wireless system as illustrated in Figure 3.
- a number of M2M applications (shown on top in Figure 3) communicate with a M2M service layer (shown as a box below the M2M applications) to provide functionality to exchange information with M2M devices (shown at the bottom in Figure 3).
- M2M devices use a wireless wide area network (WWAN) to connect to the M2M service layer
- WWAN wireless wide area network
- a M2M application sitting on top of the M2M service layer or a M2M application running on one of the M2M devices may request the M2M service layer to establish an exchange of information between the requesting M2M application and a specific M2M device or a group of M2M devices.
- the M2M service layer may contact the core network of the underlying wireless network, e.g., WWAN, to connect to the addressed M2M device. For example, if the M2M device is currently not attached to the network, it would establish the attachment. For example, if the addressed M2M device is not 100007
- the wireless network-initiated attach procedure may be triggered by a special message from the M2M service layer on the wireless network side or by a normal domain name system (DNS) query.
- DNS domain name system
- the wireless network does not have the normal context information for the M2M device which is addressed by the M2M service layer and therefore a special paging message may be introduced.
- the wireless network-initiated attach procedure may operate as follows:
- SGSN/MME serving GPRS support node/mobility management entity
- the paging agent generates a paging message which is similar to paging
- a long term ID which is not allocated by the wireless network itself (e.g. fully qualified domain name (FQDN) or a long term ID (LTID) that was established during a first contact between M2M device and service layer).
- FQDN fully qualified domain name
- LTID long term ID
- the M2M device knows by means of an agreed rule how to determine the time instances at which it is supposed to listen to paging indicators (either on the existing paging channels or on new ones) as a function of the FQDN or long term ID.
- the disclosed approach allows reducing the context that needs to be kept by the wireless network for an M2M device which is not registered to the wireless network to almost zero, beside the allocation of the fully qualified domain name (FQDN) or long term identifier (LTID) plus the cell or group of cells in which the paging needs to occur.
- FQDN fully qualified domain name
- LTID long term identifier
- the wireless network-initiated attach procedure may also use the existing paging mechanisms for devices that are already registered but not attached.
- the disclosed approach contains a new paging mechanism which may be used to page M2M devices that are currently not registered in the wireless network, but for which a long term ID (LTID) has been established already.
- the disclosed approach may be coupled with the flexibility to allow for very long paging cycles to enable long battery life on the M2M device side.
- a registration-less paging procedure may include one or more of the following steps:
- the M2M device which just established its long term ID with the M2M service layer is of the special type that can use the new paging mechanism.
- the core network records the cell or a set of cells that comprise the coverage area of the M2M device and maps this coverage area to the established long-term ID of the M2M device. In one aspect, this information is the small context that is maintained in 100007
- this context is kept static (i.e., not updated) until requested by the M2M device (e.g. when M2M device is moved from one place to another).
- the actual mechanism in the radio access network by which the pages are sent may be the existing ones (i.e. use existing paging channels including paging indicators) or new ones (different paging channels, with no or different paging indicators).
- the M2M device may receive some paging data (e.g. paging message) with this page.
- the paging data may be a short data packet from a M2M application (e.g. user data) or it may be special data for triggering further action.
- One option for the special data is sending a command to initiate a regular attach procedure from the M2M device side.
- the proposed solutions are also applicable to M2M systems which do not use a M2M service layer.
- the proposed solutions could also be used in M2M systems where a M2M server desires to reach a M2M device through the wireless network, e.g., WW AN.
- the M2M server would just need to be able to send a request for a wireless network-initiated attach from the core network of 100007
- the concept could also be extended to initiating attachment of groups of M2M devices by the wireless network.
