As mentioned above, no matter when dynamically change the terminal capabilities information of terminal, this terminal all changes its terminal capabilities version to have new unique value based on the terminal capabilities information that changes at least.Whether therefore, can whether change the terminal capabilities information of coming easily to determine terminal based on the terminal capabilities version of terminal changes.
In the present invention, (for example utilizing the Session Initiation Protocol signaling message, select message, invitation message etc.) when coming the terminal capabilities information of exchange termination, or (for example at call setup, when exchanging the radio performance environmental information call setup message), each terminal sends its terminal capabilities version to other-end.The terminal capabilities version of other terminal that is exchanged exists in each terminal with terminal capabilities information that is exchanged and the common user ID that is associated with counterpart terminal.
Subsequently, when the composite service that includes but not limited to CSI is set up professional the connection, if based on the comparison, the terminal capabilities version that demonstrates the terminal B that is stored among the terminal A is different with the terminal capabilities version value of the current terminal B that receives of terminal A, then terminal A can notify terminal B: need the terminal capabilities version of the terminal B that store be upgraded, and the current performance information of requesting terminal B.In the memory cell of terminal A (for example, SIM or USIM) change, by under the situations such as dynamic change, the terminal capabilities version value of the terminal B that is stored in terminal A may be different from the terminal capabilities version value of the current terminal B that receives of terminal A for the terminal capabilities information of terminal B.
On the other hand, conforming method as the memory cell that is used for the storage terminal performance information that is used to keep terminal, the invention provides a kind of like this method, wherein when the terminal capabilities information dynamic change of terminal, utilize the content that sends this variation such as another terminal of the common user ID of method in having the memory cell that is stored in this terminal of LBS.
Fig. 5 illustration the terminal capabilities version that utilizes of first embodiment of the invention carry out the method for composite service.The method of Fig. 5 comprises the method for the unique terminal capabilities version of aforesaid generation.The method of Fig. 5 can or realize in similar or suitable device in system in Fig. 1 and 3 and device.Can carry out and/or control by the controller 150 of terminal 100 or 200 will be by terminal 100 or 200 processing of carrying out.
As shown in Figure 5, in order to carry out the composite service that comprises at least the first business and second business, the system that utilizes the terminal capabilities version to carry out composite service can comprise first terminal 100 and second terminal 200, when connecting at first business, described first terminal 100 and second terminal 200 exchange their terminal capabilities version each other.Each terminal compares the terminal capabilities version of another terminal of the being received terminal capabilities version with this another terminal of having stored, if two terminal capabilities version differences, then the terminal capabilities information of upgrading to the described terminal request that is used to receive.
This system also can comprise and be used for providing first business network of described first business to first terminal 100 and second terminal 200, and second business network that is used for providing to first terminal 100 and second terminal 200 described second business.When this first business was based on the business (as the IMS business) of SIP, this first business network can comprise an IMS core network 410 and the 2nd IMS core network 420 that is used for providing to second terminal 200 the IMS business that is used for providing to first terminal 100 the IMS business.When described second business is the CS business, this second business network can comprise that a CS core network from the CS business to first terminal 100 that be used for providing (for example, among Fig. 1 31) and be used for providing the 2nd CS core network (for example, 32 among Fig. 1) of CS business to second terminal 200.This system also can comprise other parts, as the first and second PS core networks, first and second xRAN, first and second AS etc.The all constituents of system all is operably connected and/or is disposed.
Each terminal 100 and 200 memory cell 160 and 170 can store therein its oneself terminal capabilities version and terminal capabilities information, (for example, from formerly professional connection of other terminal acquisition) the terminal capabilities version of other terminal and terminal capabilities information and the common user ID of himself and other side's common user ID.When connecting at first business, each terminal 100 and controller/processor 150 of 200 send its terminal capabilities version to the opposing party/terminal, this the opposing party's that will receive from the opposing party terminal capabilities version compares with the terminal capabilities version that is stored in this opposing party the memory cell, and carries out that terminal capabilities exchange is handled and professionally is connected the foundation processing based on this comparative result selectivity.
Referring now to Fig. 5 the method for utilizing the terminal capabilities version to carry out composite service of first embodiment of the invention is described.Fig. 5 illustration wherein ought set up composite service and connect (that is, CSI connects) time, at first set up the embodiment that the method that CS calls out is set up in the IMS session then.This method also is applicable to only sets up the IMS session, does not promptly set up the situation that CS calls out after setting up the IMS session.
As shown in Figure 5, first terminal 100 and second terminal 200 utilize composite service (for example, current CSI service connect) exchange each other they terminal capabilities information and thereafter respectively with the terminal capabilities information stores that exchanged in the cache memory of for example each terminal.First terminal 100 and second terminal 200 are for example stored the common user ID of the opposing party's (being associated with another terminal), the terminal capabilities version of another terminal and the terminal capabilities information (S51) of another terminal respectively at least in its memory cell.Calculate the terminal capabilities version of each terminal in aforesaid mode (for example, at least based on the performance information of terminal).This terminal capabilities information can comprise for example supported coding decoder, file format etc.In addition, each in first terminal 100 and second terminal 200 wherein also stores himself common user ID, its terminal capabilities version (value), its terminal capabilities information etc.V.0.12 and V.3.3 as example, in step S51, the current performance version of first terminal and second terminal is.
Then, first terminal 100 and second terminal 200 are utilized current sessions at CSI service/is connected and carries out exchanges data and exchange of speech and the current CSI session/connection (S52) of release between first terminal 100 and second terminal 200 subsequently.At this, first terminal 100 can store the common user ID of second terminal 200, the terminal capabilities version of second terminal 200 and the terminal capabilities information of second terminal 200 therein, all these information are to set up in the process of handling at CSI to exchange, and first terminal 100 can also store the terminal capabilities version of himself therein.Second terminal, 200 profits use the same method also can store the relevant this type of information of terminal capabilities information with first terminal 100.When first terminal 100 is wished with second terminal, 200 another CSI service of execution, use the described information that is stored in this first terminal 100 after a while.
Subsequently, the terminal capabilities information of each terminal (for example, the terminal capabilities information of first terminal 100) may be owing to a variety of causes changes.For example, registering or (for example nullifying the IMS business, PoC (Push to talk over Cellular), IM, broadcasting etc.), multimedia equipment dynamically is installed to first terminal 100 or removes, uses downloading service to revise new coding decoder or supported file format or the version of multimedia messaging service, MMS (MMS) is carried out more all can changing the terminal capabilities information (S53) of first terminal 100 under the news from first terminal 100.
When the terminal capabilities information of first terminal 100 changed, this first terminal 100 for example changed its terminal capabilities version (S54) based on the performance information through upgrading of first terminal 100 at least.As a result, the current terminal capabilities version of present first terminal 100 is different with the terminal capabilities version of this first terminal 100 in being stored in second terminal 200.For example, because the terminal capabilities version of first terminal 100 is because the change of the terminal capabilities information of this terminal and from V.0.12 becoming V1.12, so the current terminal capabilities version of present first terminal 100 and the current terminal capabilities version (promptly V.0.12) different (S55) that is stored in this first terminal 100 in second terminal 200.
Thereafter, when first terminal 100 is wished with second terminal, 200 execution CSI service, the session connection that this first terminal 100 is attempted at the IMS business.Here, this first terminal 100 determines that it has stored the information relevant with second terminal 200, and not under the situation of exchange terminal capabilities information, carries out IMS session foundation by sending invitation message immediately between the two.The current terminal capabilities version (V1.12) that comprises first terminal 100 in the invitation message.First terminal 100 can generate invitation message and send the invitation message that is generated to described second terminal 200 with reference to the information that is stored in second terminal 200 wherein.The information that is stored in second terminal 200 in first terminal 100 can comprise the common user ID and the terminal capabilities information of second terminal 200 at least.
Send invitation message (S56) from first terminal 100 to second terminal 200 via an IMS core network 410 and the 2nd IMS core network 420.
Second terminal 200 obtains to be included in the terminal capabilities version of first terminal 100 in the received invitation message.Second terminal 200 (for example, V.1.12) (for example, V0.12) compares the terminal capabilities version of first terminal 100 that received with the terminal capabilities version that is pre-stored in this first terminal 100 in second terminal 200.Second terminal 200 is selected according to comparative result and is carried out that the terminal capabilities information exchange is handled and send one (S57) in handling at the response of IMS session connection request.
For example, if the terminal capabilities version of first terminal 100 that receives is identical with the terminal capabilities version of first terminal 100 of pre-stored, then second terminal 200 determines that the current terminal capabilities version of first terminal 100 after having carried out CSI service does not formerly change, and therefore determines message in response to invitation message transmission 200.Yet, if the terminal capabilities version of the first received terminal 100 is different with the terminal capabilities version of first terminal 100 of pre-stored, then second terminal 200 determines that the current terminal capabilities version of first terminal 100 after having carried out CSI service formerly changes, and therefore carries out the terminal capabilities information exchange and handle to obtain the current performance information of first terminal 100.That is the terminal capabilities information of second terminal 200 after 100 transmissions of first terminal select request message (sip message) with the change of asking first terminal 100.Select request message can comprise the current terminal capabilities version of second terminal 200.Send selection request message (S58) from second terminal 200 to first terminal 100 via an IMS core network 410 and the 2nd IMS core network 420.
Receive first terminal 100 of selecting request message and send its terminal capabilities information to second terminal 200.The terminal capabilities information of the new change of these second terminal, 200 these first terminals 100 of storage.Therefore, each in first terminal 100 and second terminal 200 all obtains and has stored the current terminal capabilities information and the current terminal capabilities version of another terminal.
After, if necessary, first terminal 100 and second terminal 200 can be carried out the CS call setup by the first and second CS core networks and handle so that CSI service to be provided.It is known that the CS call setup of CSI service is handled.
Therefore, when the terminal capabilities information of terminal changes, the terminal capabilities version can be retained as unique value, and be sent to the opposing party or more subsequently, whether the terminal capabilities information that can determine each terminal thus changes, determines based on this then, if terminal capabilities information changes, then can the requesting terminal performance information, stably use the memory cell of each terminal thus.Therefore the invention provides effectively a kind of and be used for composite service (for example, the system and method for exchange terminal capabilities information CSI) efficiently.
Fig. 6 illustration the terminal capabilities version that utilizes second embodiment of the invention carry out the method for composite service.The method of Fig. 6 comprises the method that generates aforesaid unique terminal capabilities version.The method of Fig. 6 can realize in the system of Fig. 1 and Fig. 3 and device or other similar or suitable systems/devices.Can carry out and/or control by the controller 150 of terminal 100 or 200 will be by terminal 100 or 200 processing of carrying out.
As shown in Figure 6, the system that utilizes the terminal capabilities version to carry out composite service according to the present invention can comprise first terminal 100 and second terminal 200, an IMS core network 410 and the 2nd IMS core network 420 and a CS core network 310 and the 2nd CS core network 320.Fig. 6 illustration be used to carry out the method for composite service, wherein, when this composite service is CSI service, at first sets up CS and call out and set up the IMS session subsequently.
Use the method identical to come execution in step S61 with the method for S51 that is used for Fig. 5 and S52.When the CSI service of having finished between first terminal 100 and second terminal 200, with common user ID, terminal capabilities information and the terminal capabilities storage of versions of each terminal in another of first terminal 100 and second terminal 200 (S61).That is, step S61 is identical with S52 or similar with the step S51 of Fig. 5.
As example, suppose the following information of storage in first terminal 100:
Second terminal; Bobs@lge.com; Text-audio-video-Motion Picture Experts Group (MPEG)-codec type etc.; V.3.3.
Wherein second terminal 200 (for example, URI) common user ID is bobs@lge.com, but the support terminal performance information of second terminal 200 is represented text, audio frequency, video, Motion Picture Experts Group (MPEG) and various coding decoder, and V.3.3 the current terminal capabilities version of second terminal 200 is.
After this, each in first terminal 100 and second terminal 200 can dynamically change their terminal capabilities information under the situation of registration and cancellation IMS business, installation and removal multimedia device etc.As embodiment, below will describe at the reformed situation of terminal capabilities information of first terminal 100.
When the terminal capabilities information of first terminal 100 was changed, this first terminal 100 used at least the terminal capabilities information through changing (can in conjunction with or not in conjunction with the additional information such as common user ID and/or private subscribers ID) to generate the new terminal performance version (S62 and S63) with unique value.As example, V.0.12 the version of terminal capabilities formerly of first terminal 100 is, and V.1.12 the terminal capabilities version of newly-generated (through changing) is.
Subsequently, want at first to set up CS when first terminal 100 and call out when carrying out CSI service with second terminal 200, first terminal 100 sends CS call setup messages (for example, setting up message) (S64) to second terminal 200.The CS call setup message can comprise the terminal capabilities version of first terminal 100 at least.For example, the current terminal capabilities version (value) (V.1.12) that in this call setup message, comprises first terminal 100.Send call setup message from first terminal 100 to second terminal 200 via a CS core network 310 and the 2nd CS core network 320.
Then, second terminal 200 sends connection message CONNECT (S65) in response to call setup message to first terminal 100.This connection message CONNECT can comprise the terminal capabilities version (for example, V.3.3) of second terminal 200 at least.Can send this connection message CONNECT from second terminal 200 to first terminal 100 via a CS core network 310 and the 2nd CS core network 320.
After finishing the CS call setup, in order to set up the IMS session of CSI service, first terminal 100 with the terminal capabilities version of second terminal 200 of pre-stored (for example, V.3.3) with at the terminal capabilities version (for example, V.3.3) of setting up second terminal 200 that receives when CS calls out compare (S66).According to this result who compares, first terminal 100 is selected and is carried out the terminal capabilities information exchange and handle or select immediately and carry out IMS session foundation processing.
For example, in step S66, if the terminal capabilities version of second terminal 200 of pre-stored is different with the terminal capabilities version of second terminal 200 that receives, then first terminal 100 determines that the terminal capabilities version of second terminal 200 since the CSI service of carrying out formerly variation has taken place.Therefore, first terminal 100 is carried out terminal capabilities information exchange/transmission and is handled, wherein first terminal 100 to selection request message that second terminal 200 sends SIP with request and receive from the terminal capabilities information after the change of second terminal 200 of second terminal 200 (not shown among Fig. 6, but the selection that is similar to Fig. 2 is handled).
Yet, in step S66, if the terminal capabilities version of second terminal 200 of pre-stored (for example, V.3.3) with the terminal capabilities version of second terminal 200 that receives (for example, the terminal capabilities information of second terminal 200 of the current terminal capabilities information that V.3.3) identical (this is the situation in the present embodiment), first terminal 100 are determined second terminal 200 when carrying out CSI service formerly is identical.That is, the terminal capabilities information of second terminal 200 does not change.Therefore, the selection request message that first terminal 100 does not send at terminal capabilities information to second terminal 200, but it is set up the invitation message (S67) of IMS session to 200 transmissions of second terminal.Here, invitation message can comprise the terminal capabilities version of first terminal 100 at least.Here, the terminal capabilities version of first terminal 100 for example is V1.12.Send this invitation message via an IMS core network 410 and the 2nd IMS core network 420 to second terminal 200.
Then second terminal 200 will utilize the terminal capabilities version of first terminal 100 that described invitation message receives to compare (S68) with the terminal capabilities version that before had been stored in first terminal 100 wherein.According to result relatively, in terminal capabilities information exchange processing and the IMS session connection processing is selected and carried out to second terminal 200.For example, second terminal 200 sends the terminal capabilities information request of first terminal 100 or about the response of IMS session connection request to first terminal 100.
Promptly, in step S68, if the terminal capabilities version of first terminal 100 that receives is identical with the terminal capabilities version of first terminal 100 of having stored, then the second terminal 200 current terminal capabilities information of determining first terminals 100 is identical with terminal capabilities information from CSI service formerly, therefore send 200 acknowledge messages (not shown among Fig. 6, but be similar to the step of Fig. 2) in response to invitation message to first terminal 100.
Yet, in step S68, if the terminal capabilities version of first terminal 100 that receives is different with the terminal capabilities version of first terminal 100 of having stored, for example, if the terminal capabilities version that receives is that the terminal capabilities version of V1.12 storage is V0.12, then the second terminal 200 current terminal capabilities information of determining first terminals 100 is different with terminal capabilities information from CSI service formerly.In other words, the second terminal 200 terminal capabilities information of determining first terminal 100 changes.So the terminal capabilities information (S69) of second terminal 200 after 100 transmissions of first terminal select request messages with the change of asking first terminal 100 thus.Here select request message can comprise the terminal capabilities version of second terminal 200.
Receive first terminal 100 of selecting request message and then utilize and select the terminal capabilities information of response message after second terminal 200 sends it and changes, thereby make second terminal 200 can obtain to be used for the current performance information of first terminal 100 of CSI service.
Therefore, second terminal 200 store therein after the change of first terminal 100 terminal capabilities information and with the change of first terminal 100 after the performance version of corresponding this first terminal 100 of terminal capabilities information.Therefore, the present invention has kept the current terminal capabilities information of first terminal 100 and has been stored in consistency between the terminal capabilities information of first terminal 100 in second terminal 200.
Subsequently, handle the IMS session of setting up between first terminal 100 and second terminal 200 by known IMS session foundation, and between the two, exchange real data (medium) (S70).
In step S64, if comprised the terminal capabilities version of first terminal 100 to the CS call setup message of second terminal 200, then second terminal 200 can compare the performance version of first terminal 100 that the receives performance version with first terminal 100 of having stored, and can the execution performance information exchange handles (if version difference) or directly carry out the IMS session and set up and handle (if version is identical).
Therefore, each in first terminal 100 and second terminal 200 is all used at least unique terminal capabilities version of another terminal that the current terminal capabilities information based on another terminal generated.This has prevented the inconsistent problem between the terminal capabilities information of terminal capabilities information that receives and pre-stored, and has simplified the signaling process that connects at composite service.In addition, handle, so reduced network burden and CSI service is handled effective and efficiently owing to just carry out terminal capabilities information exchange/transmissions under the terminal capabilities version that only ought the receive situation different with the terminal capabilities version of the corresponding terminal of pre-stored.
In addition, a user has a plurality of terminals and the identical common user ID of the common use of this a plurality of terminals usually.Here, in common composite service system, each terminal based on common user ID (for example, URI) storage terminal performance information, and therefore (for example be difficult to utilize same common user ID, URI) distinguish each terminal capabilities information of a plurality of terminals, thereby cause existing in the terminal capabilities information some inconsistency.Yet, the present invention can be for example by using hash function or other encryption/coding techniquess, at least based on the terminal capabilities information of the private subscribers ID of the common user ID of terminal, terminal and this terminal or generate unique terminal capabilities version based on the common user ID and the terminal capabilities information of terminal at least.Therefore, even have a plurality of terminals and all terminals are all used under the situation of identical URI, also can generate different terminals performance version based on the terminal capabilities information of each terminal with unique value a user.
Therefore, according to the present invention, each terminal all has the unique terminal capabilities version based on the current terminal capabilities information of this terminal, thereby can distinguish each terminal capabilities information of a plurality of terminals and these a plurality of terminals.
In addition, in the prior art, because Calling Side is confirmed the pre-stored information of receiver side, determine whether terminal capabilities information is changed (renewal), and carry out the terminal capabilities information exchange subsequently and handle, so when the particular terminal of Calling Side user in a plurality of terminals that belong to this user set up call forwarding function in advance, need not to carry out the terminal capabilities information exchange and handle.
Yet, in the present invention, if there is variation in the terminal capabilities version during call setup and session foundation, the particular side (that is, Calling Side or receiver side) that then receives the terminal capabilities version of opposite side compares the terminal capabilities version of reception and the terminal capabilities version of pre-stored to determine whether this terminal capabilities information changes.Therefore, can solve the prior art problems that when using the supplementary service that exchanges such as calling, may cause.
Fig. 7 and Fig. 8 illustration carry out the method for composite service according to the terminal capabilities version that utilizes of third embodiment of the invention.As shown in Figure 7 and Figure 8, the 3rd execution mode at when between at least the first user and second user, carrying out composite service and second user have the situation of using with a plurality of terminals of this second user-dependent same common user ID.The method of Fig. 7 and Fig. 8 comprises the method for the unique as mentioned above terminal capabilities version of generation.The method of Fig. 7 and Fig. 8 can realize in the system of Fig. 1 and Fig. 3 and device or other similar or suitable systems/devices.Can carry out and/or control by the controller 150 of terminal 100 or 200 will be by terminal 100 or 200 processing of carrying out.
As shown in Figure 7 and Figure 8, in the system that is used for carrying out according to composite service of the present invention, first user uses first terminal 100, and second user uses a plurality of terminals 200, is designated as 2-1 terminal 210 and 2-2 terminal 220 at this as example.2-1 terminal 210 and 2-2 terminal 220 are used same common user ID (for example, URI).In the method that is used for the composite service shown in execution graph 7 and 8, when composite service is CSI service, at first sets up CS and call out, and set up the IMS session thereafter.In addition, in the method for Fig. 7 and 8, second user has preset the call forwarding function that is used for Call Direrting is given 2-2 terminal 220.In this embodiment, the terminal capabilities information of each during CSI service in 2-1 terminal 210 and the 2-2 terminal 220 is constant, and first terminal 100 is dynamically upgraded its terminal capabilities information.Can have other situation, and the present invention also can be applicable to described other situation equivalently.
First terminal 100 of supposing first user has been carried out the CSI service with second user's 2-2 terminal 220 in advance, and has therefore stored common user ID, terminal capabilities information and the terminal capabilities version of another terminal in each of first terminal 100 and second user's 2-2 terminal 220.
Subsequently, first terminal 100 and second user's 2-1 terminal 210 is carried out CSI service.Therefore, in each of first terminal 100 and second user's 2-1 terminal 210, also stored common user ID, terminal capabilities information and the terminal capabilities version (S71) that is connected another terminal that is exchanged during setting up at CSI service.
That is, first terminal 100 has been stored common user ID, terminal capabilities information and the terminal capabilities version relevant with 2-1 terminal 210 therein, and has stored this type of information relevant with 2-2 terminal 220 therein.Here, the terminal capabilities version of first terminal 100 for example is 10000100, and the performance version of terminal 210 and terminal 220 for example is respectively 00101010 and 10001001.Since can in conjunction with or not under the situation in conjunction with aforesaid common user ID and/or private subscribers ID, generate the performance version of terminal 210 and terminal 220 based on terminal capabilities information, so each performance version (value) all is unique.
Subsequently, when the terminal capabilities information of first terminal 100 owing to for example first terminal 100 connects or dismantles multimedia device (as video camera) from it when changing, first terminal 100 uses the terminal capabilities information of its change to generate unique terminal capabilities version (S72) once more at least.Here, the terminal capabilities version of the first newly-generated terminal 100 for example is 10000101.
When first terminal 100 of the terminal capabilities information with change wished to carry out another CSI service with 2-1 terminal 210, the terminal capabilities information of this 2-1 terminal 210 after based on the change of first terminal 100 determined whether the current terminal capabilities information of first terminal 100 changes.That is, the terminal capabilities version of terminal 210 first terminal 100 that will receive compares to determine with the version of storage formerly.2-terminal 210 is then for example utilized and is selected request to wait request and receive from the terminal capabilities information (S73) after the change of this first terminal 100 of first terminal 100.
After this, in order all to transfer to 2-2 terminal 220, the second user's register call forwarding functions (S74 and S75) in any calling that 2-1 terminal 210 receives.For example, second user (2-2 terminal 220) register call transfer request in the 2nd IMS core network 410 suitably generates and stores call forwarding function set information (information that is associated with this call forwarding function) thus.In another embodiment, in 2-1 terminal 210 register call transfer request in the 2nd IMS core network 410, suitably generate and store call forwarding function set information (information that is associated with this call forwarding function) thus.
After this, when first terminal 100 was wished with second user (for example, 2-1 terminal 210) execution CSI service, first terminal 100 sent the CS call setup message (for example, setting up message) of the 2-1 terminal 210 of pointing to second users.For example, this call setup message can comprise first terminal 100 current terminal capabilities version (such as, 10000101).
Because registered call forwarding function, so the 2nd IMS core network 420 is then by using registered call forwarding function to send call setup message (S76) to second user's 2-2 terminal 220.
Then 2-2 terminal 220 sends connection message CONNECT (S77) in response to the call setup message that receives to first terminal 100.This connection message CONNECT can comprise for example current terminal capabilities version (as 10001001) of 2-2 terminal 220.Therefore, between first terminal 100 and 2-2 terminal 220, set up the CS calling.
