Embodiment

Equipment, method and the software of the presentation information attribute that is used for providing wireless communication system have been described.In the following description, for for the purpose of explaining and illustrate many details and understand completely of the present invention so that provide.Yet, those skilled in the art be it is evident that the present invention can need not these details and realize or use the equipment that is equal to realize.In other example, the construction and device known is shown to avoid unnecessary fuzzy the present invention with the form of block diagram.

Though describe various embodiment of the present invention at Push to talk over Cellular (PoC) business of using the spread-spectrum cellular network, be appreciated that and be contemplated that the present invention goes for other group communication business and wireless network.In addition, though discuss the present invention at IMS (IP Multimedia System business) and MMD (multimedia domain, MMD) network, those skilled in the art are understandable that the present invention goes for using any IP-based core net of other communication protocol.Equally, can be contemplated that the session that can use any kind set up agreement, internet engineering task group (IETF) session initiation protocol (SIP) or International Telecommunication Union H.323 agreement implement various embodiment of the present invention.

In addition, according to the method for various exemplary embodiments the method that is used to distribute the presentation information attribute on 3GPP (the 3rd generation partner program) IMS (IP Multimedia System) and 3GPP2 (the 3rd generation partner program 2) MMD (multimedia domain, MMD) network has been described.IMS provides IP multimedia service to mobile device, comprises PoC, VoIP (internet-protocol telephony) or the voiceband telephone, the instant message (IM) that divide into groups, presents (presence), group communication etc.For example, IMS uses session initiation protocol (SIP) as signaling protocol, this agreement in internet engineering task group (IETF) Request for Comment (RFC) 3261 (it is by being introduced at this with reference to its full content) by more detailed description.

Fig. 1 is the schematic diagram that is used to support the wireless communication system of the presentation information attribute expanded according to an embodiment of the invention.Wireless access network 101 provides 103 and 105 the communication service of accessing terminal.In the exemplary embodiment, wireless access network 101 is supported group communication business, for example Push to talk over Cellular (PoC) business; Same,

terminal

103 and 105 is configured to PoC client computer (being the PoC terminal).For the purpose of illustrating, serve PoC terminal 105 by long-range PoC network 107.

The importance of PoC service is to determine whether

terminal

103 and 105 presents (therefore available).Present availability and supported by presence server 111, it is for accepting, store and distribute the entity of presentation information.Presentation information according to an embodiment can offer presence server 111 so that terminal 103 and 105 (being the observer) is issued by application server 109.

Each PoC terminal 103,105 can be supported such as hardware performance and softwares such as speaker-phone and/or earphones, accepts session immediately as long as this software provides the user to dispose PoC terminal 103,105 and initiates and receive medium do not need called subscriber's intervention with regard to playing these medium performance.This operator scheme is known as autoanswer mode or automatic mode.The user selectively disposes PoC terminal 103,105 at first to notify the user and require this user initiation that manually accepts session before medium are accepted.This operator scheme is known as manual answer mode.PoC terminal 103,105 can be supported these two kinds of operator schemes or only support one of these operator schemes.For example, the user can easily change answer-mode (AM) configuration of PoC terminal 103,105 based on present case and hobby (for example, the line is busy now or come the public domain for the user, is inappropriate thereby use speaker-phone).

Also each PoC terminal 103,105 can be configured to session initiation protocol (SIP) user agent (UA).As SIP UA, PoC terminal 103,105 can be established to the session of one or more SIP UA simultaneously; Can initiate this communication by pressing " conversation " button by the user.Except PTT, SIP PoC terminal 103,105 can also be supported various communication services based on SIP (for example, voip phone, present business, messaging service or the like).The user can require to forbid accepting the PTT session sometimes, and is that one or more other business based on SIP keep the SIP that is registered.When with this PoC terminal configuration when not accepting the PTT session of any incoming call, this configuration is called the incoming call session forbids (ISB).

In addition, the user can require to get in touch to have and make the incoming call session forbid the user of the PoC terminal that can carry out.Under this situation, the user can send to this other user with instant individual's notice and seek PoC session with indication.Even when purpose PoC terminal has made the incoming call session forbid carrying out, also receive this instant individual's notice.If the user wants to forbid accepting instant individual's notice, then the user can be with the PoC terminal configuration for not accepting the instant individual's notice of any incoming call; This is known as instant individual's notice and forbids (IAB).

For satisfied communication experiences is provided to the user, must make the initial session that receives the time of conversation indication from time that the user presses the button to the user set up delay minimization.The factor that this delay is worked is to determine presenting of targeted customer.

Move open alliance (OMA) and defined the set of supporting the requirement of PoC service.More specifically, " OMA (Open Mobile Alliance) presence SIMPLE enabler " defined the presentation information unit that is known as " application-specific availability ".This unit indicates whether to use the business of appointment and the communication request that device (if it is designated) receives incoming call.For example, if presenting body (for example, terminal 103) is provided with PoC service and satisfies one or more conditions and (for example, be positioned at the coverage of network 101, be suitable handheld device (according to hardware and/or software arrangements) etc.), then the user will be available to the PoC service.Yet if any one in these conditions is not true, the user will be " disabled ".

" OMA presence SIMPLE enabler " also defined the data format that " application-specific availability " can be mapped as the presentation information data format (PIDF) that adopts following system:＜tuple〉→＜status →＜basic → open/colsed and＜service-description.Yet, should be realized that this system is restricted inadequately.That is to say, be used for the binary system＜basic of availability〉" open " and " closed " value, the observer about can the understanding of the expectation of the future value of availability being restricted.

Under the situation of OMA PoC service, when users from networks was nullified, user's availability was set to " closed ", and forbade (ISB) sign when (perhaps designator) when the user opens the incoming call session, and also user's availability is set to " closed ".Both of these case is represented different user behaviors, still, under the situation that adopts the OMA pattern, has no idea to distinguish these different situations.When user log off, the observer can expect PoC user's unavailable in the near future (for example, the user can on holiday and close device).But when the ISB sign was set up, the observer can expect that PoC user's unavailability is interim.In other words, the user will be available (for example, the user is holding important meeting, therefore opens ISB owing to not wanting to be bothered by anyone/interrupt) very soon.

Method according to an embodiment of the invention adopts further login state, illegal state and the session participant status information of the details of indication availability information to come basic, the binary type of extended availability.In one exemplary embodiment, can obtain this information from session initiation protocol (SIP) login state event packets.As mentioned above, terminal 103,105 can adopt SIP to set up and terminate in communication session between them.The critical function of SIP is registration operation, and it is provided at the binding between the URI of SIP unified resource identifier (URI) (being recording address (address-of-record)) and one or more contacts.The SIP register method allows the user agent to handle registration; For example, contact can be added or delete, the strategy that stops undelegated access can be carried out.Under Session Initiation Protocol, therefore the post-registration expiration, need effectively refresh during necessarily.

Fig. 2 is the schematic diagram of registration process of terminal that is used for the system of Fig. 1.The IETF RFC 3680 that is called " ASession Initiation Protocol (SIP) Event Package for Registration (session initiation protocol that is used for registering (SIP) event packets) " in name describes the login state event packets in detail, is incorporated herein its full content and as a reference.RFC 3680 has defined following state-event: initial (" Initial ") state 201, state of activation 203 and state of termination 205.Yet for determining to present availability, it is useful having only state of activation and state of termination.Use incident illustrate relevant to be used for the finite state machine 200 of registration process with presentation information is provided.These finite state machine 200 each contact status machines of expression, thus when contact is registered, this state machine of illustration, and when the cancellation contact, just delete this state machine.When not having the contact that is registered to recording address, this state machine is in initial condition.When contact was registered to recording address, state machine 200 was transformed into state of activation 203 from initial condition 201.That is to say, when adding new contact, illustration its finite state machine and to the conversion of state of activation 203.If the contact that exists at least one to be tied to recording address, then state machine 200 resides in state of activation 203.When last contact expired or is cancelled, registration was transformed into state of termination 205.

According to embodiments of the invention, application server 109 (Fig. 1's) can be the user (subscriber) of registered events grouping.When in recording address or each contact status machine, any incident taking place, the user is produced notice.Interested incident comprises registration, refreshes, expiration, unregistered and refusal.Can be with some login state, for example state of activation 203 and state of termination 205 are mapped to presentation information.

In addition, for the OMA PoC service, defined the greatest measure that the availability information that adds is represented following state information: ISB (the incoming call session is forbidden), IAB (instant individual's notice is forbidden) and reached simultaneous (or concurrent) PoC session that is allowed.

Fig. 3 A and 3B are the flow charts of method that is used to provide the presentation information of expansion according to an embodiment of the invention.According to one embodiment of present invention, application server 109 can be followed IP Multimedia System (IMS) structure.In presentation information is provided, will be described as follows alternately between application server 109 (for example, PoC server) and the presence server 111.

In step 301, application server 109 can divide into groups by the subscription registration state event, with the renewal of reception incident (or state) change.Should be realized that login state can be regarded as a kind of presentation information, but can not directly be used for presenting, because presence server 111 expectations provide all issues-for example, presentation information data format (PIDF) with form strictness, regulation.In 3GPP TS 34.229 and 3GPP2 X.S0013-004-A, describe in detail about the application server process how the subscription registration state event divides into groups, be incorporated herein it in full as a reference.

According to embodiments of the invention, application server 109 uses login state (for example, as defined among the RFC3680) as the input to presentation information.In other words, login state is mapped as present availability (according to step 303) thus provide additional value to availability.Next, come issuing and presenting information according to form as defined in the step 305.

As selection, application server 109 itself can have the knowledge (situation of describing among Fig. 3 B) of state information.For example, suppose that application server 109 is PoC servers, then can use PoC that event packets is set ISB or IAB designator directly are set on PoC server 109.Under this situation, determined as by the set illegal state of portable terminal 103, the i.e. state (step 311) of ISB or IAB designator.In another kind of example, suppose that application server 109 is PoC servers, the PoC server determines whether PoC user has reached the greatest measure (step 311) of the concurrent PoC session that is allowed.

According to step 313, when application server 109 was known state information, application server 109 can directly be suitable presenting form and issue this attribute (as the expansion of availability) as presentation information with best property of attribute mapping.

According to embodiments of the invention, presence server 111 uses presentation information data format (PIDF) to gather presentation information.In the RFC 3863 (this quote it in full as a reference) of title, defined PIDF for " Presence Information Data Format (PIDF) (presentation information data format) ".Like this, in the exemplary embodiment, can adopt login state, illegal state and session participation information to expand PIDF.The expansion that can be used as PIDF defines the extensible markup language of this information (XML) form.In the exemplary embodiment, can specify three expanding value＜registration-state 〉,＜barring-state〉and＜session-participation 〉.

Table 5

Fig. 4 is the schematic diagram that can support to present professional example wireless PTT (PoC) structure according to an embodiment of the invention.In order to support PoC service, PoC client computer 401 and PoC server 403 with present module 405 and be connected by interface, to guarantee that the presentation information about the PoC client computer is known.Presenting module 405 (it can be configured to presence server) is acceptance, storage and the distribution entity about the presentation information of PoC client computer.Issue the presentation information of representing the PoC client computer by PoC server 403.This information can the observed person or is represented the PoC server 403 of PoC client computer to subscribe to.According to various embodiments of the present invention, state information (for example, login state, illegal state, session participate in) comprises the availability that presents of determining PoC client computer 401.As shown in the figure, for example, can utilize ISB sign 407a or IAB sign 407b that additional availability information is provided.

Present module 405 and carry out alternately, the XML document (for example, specific PoC document, URI contact list etc.) of XML document management (XDM) module 409 managed storage in network with XML document management (XDM) module 409.In other management function, XDM module 409 can be subscribed to the change that these XML document are carried out, wherein, and reception notification when document change occurs.XDM module 409 can be implemented in fixing terminal or subscriber equipment.

The performance of the presence server 405 of PoC client computer 401 and support PoC service will further describe as follows.As shown in Figure 1, PoC client computer 401 can insert PoC service, and can reside in access terminal (for example, moving).PoC client computer 401 is configured to provide PoC session initiation and release and carries out and use for example registration of SIP/IP core 411.PoC client computer 401 also can be carried out the subscription authentication to SIP/IP core 411.In addition, PoC client computer 401 adopts the process and the agreement that are associated to produce and exchange right to speak (talk burst) (promptly, PoC service), this process and agreement be such as floor control process, right to speak control protocol consult, answer-mode indication (manual answering, automatic-answering back device) is set performance, incoming call session forbid and if instant individual's notice is forbidden, concurrent PoC session support and carry out the initialized user plane procedure of adaptation by PoC server 403.

PoC server 403 provides two major functions to activate PoC service: control PoC function and participation PoC function.During setting up, PoC session determines the special role (control or participation) of PoC server 403, and the setting during the preserving sessions.In PoC session, there is a PoC server 403 carrying out control PoC function; Yet it can be one or more carrying out the PoC server that participates in the PoC function in PoC session.

As the part of its responsibility in execution control function, PoC server 403 can be managed SIP session and the medium and the right to speak control communication path of a quantity of the N in the PoC session, and wherein, N is the quantity of the participant in the PoC session.On this, by the PoC client computer carry out being participated in the PoC server of PoC function, PoC server 403 can with such as medium such as right to speak control messages and the signalling route relevant with medium to PoC client computer 401.In this example, suppose PoC server 403 just in execution control function, and another PoC server (not shown) is assumed to be the participation function.Carrying out the PoC server that participates in the PoC function can allow PoC server 403 (carrying out control PoC function) to have medium and the signaling relevant with the medium direct communication path to each PoC client computer 401.It should be noted, for the PoC session signaling, PoC server 403 not with 401 direct communications of PoC client computer; Yet when PoC client computer 401 was carried out the participation function, PoC server and PoC client computer 401 communicated.

In addition, as mentioned above, PoC server 403 can play observer's effect.In this performance, server 403 can be to presenting business (for example, presenting module 405) request presentation information, so that the arbitration that presents attribute that is provided for the PoC session strategy execution (for example, the PoC client computer " can not arrive " state, the PoC that carries out the PoC client computer present be provided with etc.).It should be noted that PoC server 403 can be supported to be used for the strategy execution that PoC session is handled, it is based on relevant with PoC or general presentation information.

As shown in the figure, discovery and Registering modules 413 are carried out the SIP registration of SIP/IP core 411, and PoC service is supported in indication in register requirement.After PoC user successfully registers, can begin communication.In addition, authentication/authorization module 415 provides PoC client computer 401 to insert the authentication of PoC service.

For the purpose of illustrating, in the situation of 0MA PoC service, described the specific presentation information of PoC unit and presented process.Specify one group of display unit to express PoC user's the present condition that is.Table 6 has been enumerated the display unit that is mapped to each presentation information unit.
