Abstract
The need to enable wireless presence-based services more efficiently is addressed by embodiments of the present invention. A wireless presence proxy (WPP 415) monitors the messaging and messaging responses of a mobile station (MS 401) via wireless transceiver equipment (411). Such messaging and messaging responses do not explicitly specify a presence state or state change for the MS. Thus, based upon this monitoring, the WPP infers the presence state/change for the MS and maintains MS location information. The WPP communicates any presence state changes and confirms MS presence state as required by the presence server(s) (225). By monitoring messaging, notifying the server(s) of MS presence, and handling server requests (potentially from many servers for the same MS), embodiments of the present invention reduce or avoid many existing inefficiencies, such as wide area paging and call set up and tear down for each presence ping, from each presence server.

Those skilled in the art will recognize that Fig. 2-4 does not have trace system 200,300 and the required overall network equipment of 400 operations, and only is for the description of embodiments of the invention relevant especially those system components and logic entity.For example, cordless communication network 410 is depicted as and comprises radio transceiver device (WTE) 411 and wireless presence status agency (WPP) 415.In some embodiments consistent with cordless communication network 410, WTE 411 is included in one or more base station transceivers station (BTS), supports to involve the message of MS 401 and the transmission and the reception of message response.
WPP 415 can use well-known assembly to realize, processor for example, and memory, and/or be designed to the logical circuit of implementation algorithm, this algorithm is explained as computer instruction and/or in circuit.Given algorithm or logic flow, those skilled in the art know the many design and development technology that can be used for realizing carrying out the WPP of given logic.For example, the WPP consistent with the present invention (for example can be embodied as the one-of-a-kind system assembly, controlled function), be integrated into the well-known system component (controlled function among the MSC for example, perhaps described as the WPP among the PCF 214 215), perhaps be distributed between the well-known system component (as be distributed in WPP 315 between MSC 313 and the PCF 314 described).
Abide by the first embodiment of the present invention and describe cordless communication network 210.Network 210 comprises well-known system component MSC/VLR 213 and PDSN 216.In addition, network 210 comprises PCF 214, and WPP 215 is integrated in wherein, also comprises BS 212, and it comprises WTE (for example WTE 211), BTS, base station controller (BSC), also comprises selecting and Dispatching Unit (SDU).
Abide by the following basically generation of operation of the communication system 200 of the first embodiment of the present invention.Message and the message response of WPP 215 monitoring MS 201 are as receiving via WTE 211.Message response comprise such as page response, short bursts of data (SDB) affirmation, status response message, Short Message Service (SMS) confirm, with signaling such as layer 2 affirmation.Message comprises MS indication, i.e. its start shooting or shut down (power up or down), registration or nullify enters or withdraws to obtain (unavailable) pattern, switch to outside the cordless communication network 210 or within, perhaps participate in or finish other communication.These signalings are used in and do not provide in the system of attending status service today.Like this, these message responses do not require special software among the MS 201, and they are the not presence status change of the presence status of explicitly appointment MS 201 or MS 201 also.Therefore, based on its monitoring, WPP 215 infers that the presence status of MS 201 and/or state change.WPP 215 is transferred to presence status server 255 with this presence status and/or the state change of MS 201 thereafter.This communication takes place via PDSN 215, and internet usage message and Session initiation Protocol (SIP).
For inferring presence status/change of MS 201, message and the message response of WPP 215 monitoring MS 201.For example, if the presence status of MS 201 is indicated its " existence ", when WPP 215 detects instruct MS 201 and is shutting down, nullifying, enters can not acquisition model, switch to outside the cordless communication network 210 or when participating in the message of other communication, the presence status of WPP 215 deducibility MS 201 becomes " not existing " state.Similarly, if the presence status of MS 201 indicates it " not exist ", when WPP 215 detects instruct MS 201 and is starting shooting, registering, withdraws from can not acquisition model, switch within the cordless communication network or when finishing the message of other communication, the presence status of WPP 215 deducibility MS 201 becomes " existence " state.
In first embodiment, WPP 215 signals to MS with the message that requires the MS response once in a while.This signaling can be by receiving request Event triggered such as (for example, ping requests) such as the timer expiration at periodicity timer expiration, the interval that is set to select at random or from presence status server 225.Require the message of MS response to comprise such as message such as paging, short bursts of data (SDB) message, status request message and Short Message Service (SMS) message.
Based on the message and the message response of WPP 215 monitorings, WPP 215 safeguards the Last Known Location information of (that is, storage and/or renewal) MS 201.In first embodiment, Last Known Location information is sub-district ID, although as alternative another kind of replacement scheme, it can comprise base station IDs, one group of sub-district ID or location area codes (LAC).By stored position information by this way, can be only signal to MS 201 in its sub-district of operating (or a plurality of sub-district) thinking.This helps first embodiment to support the efficient of presence status.
When WPP 215 receives the message response of the signaling that responds its initiation, do not change in the presence status of WPP 215 deducibility MS 201.Can be that MS 201 has changed the position, that is, MS 201 be from being different from responding about the indicated sub-district of the Last Known Location information of MS 201 by WPP 215.In this case, WPP 215 upgrades its Last Known Location information about MS 201.And WPP 215 can confirm the presence status (although it does not change as yet) of MS 201 to presence status server 225.This affirmation can allow presence status server 225 its ping timers about MS 201 of replacement.Similarly, WPP 215 also can use in its presence status of inferring MS 201 and not change, and begins or stop the timer that it is used to safeguard the presence status information of MS 201.
WPP 215 may not receive the response to the signaling of its initiation.WPP 215 will use timer (or a plurality of timer) to set up response period, wait-for-response in this period, wait for any repetition signaling and etc. the trial of signaling (for example the signaling of MSC guiding is described below) of other form to be used.When not receiving response in response period, the presence status of WPP 215 deducibility MS 201 becomes " not existing " from " existence ".
When WPP 215 abides by the signaling that its Last Known Location information is initiated to MS 201, but when BS 212 does not receive from the response of MS 201, BS 212 request MSC 213 use its about the paging positional information of MS 201 to MS 201 signal (that is the signaling of MSC guiding).If MS 201 has changed the position, then MS 201 should, although be from being different from by the indicated sub-district of the Last Known Location information of WPP 215, responding.By this way, can confirm the presence status of MS 201, and upgrade the Last Known Location information of WPP 215.
Fig. 5 abides by the first embodiment of the present invention, and support is based on the message flow chart of the message of the service of presence status.WPP 215 can be from the request (for example presence status request message 501) of presence status server 225 (via PDSN 216) reception for the current state of MS 201.As an alternative, WPP 215 can oneself once in a while (may periodically) seek to confirm the presence status of MS 201.Trigger event person why no matter, WPP 215 sends the signaling request messages to BS 212, specifically, is exactly A9-short data delivery of messages 502, and its indication signaling position (for example, sub-district ID) signals to MS 201 in this position.BS 212 signals to MS 201 with short bursts of data 503 on paging channel in indicated sub-district thereafter.
In first embodiment, MS 201 confirms that with layer 2 504 respond on access channel, and this confirms to be received by BS 212.Yet MS 201 needn't respond, and BS 212 can send about whether receiving the indication from the response of MS 201 to WPP 215.Specifically, be exactly that BS212 sends A9-short data acknowledgment message 505 to WPP 215, instruct MS 201 has responded.According to this message response, WPP 215 is the presence status of deducibility MS 201 thereafter.If necessary, WPP 215 uses presence status renewal/acknowledge messages 506 to upgrade or confirm this presence status to presence status server 225 (via PDSN 216).Only for presence status changed, perhaps when 225 requests of presence status server were confirmed, it is essential that this presence status server message is only.
Fig. 6 is the logical flow chart of the function of being undertaken by the wireless communication system of abideing by the first embodiment of the present invention.Logic flow 600 beginnings (602) detect message and the message response of MS in cordless communication network.Based on this monitoring, network operation (604) is about the Last Known Location information of this MS, and the presence status of deduction (608) this MS.If (610) the MS presence status changes, if perhaps the presence status server has asked presence status to be confirmed, network is given the requested service device with the state transfer of the deduction of this MS or is needed the server of notice new state.Logic flow 600 is returned frame 604 thereafter, to continue this monitoring circulation.
When monitoring circulation, wireless network also can be waited for trigger event, this trigger event indication: checked the presence status of MS in time.Such trigger event comprises the expiration of network presence status timer and the reception of presence status server requests.When (614) trigger event takes place, by the indicated place of Last Known Location information, network with the message that requires the MS response to MS signal (616).Logic flow 600 turns back to frame 614 thereafter, to continue this signaling circulation.
