In the first embodiment of Fig. 4, if the current terminal capabilities information of terminal (namely, the first terminal performance information) be to comprise the performance group with following information, namely comprise and have 256 looks, the screen performance of 640 * 486 resolution, the 256MB memory, reinforced full rate (EFR), adaptive multi-rate (AMR), Motion Picture Experts Group 4 (MPEG4), comprise codec type H.264, and the browser type of WAP 1.2, then this terminal has first terminal performance information input hash function the first terminal performance version of unique value with generation.As shown in Figure 4, for example this first terminal performance version can be ' 0,100 1000 '.
In the second embodiment of Fig. 4, when video camera being connected on the terminal and therefore changed the performance of terminal, this terminal is inputted the current terminal capabilities information (that is, the second terminal capabilities information) with the camera function that adds on it has unique value with generation the second terminal capabilities version in hash function.Here, the second terminal capabilities version that for example generates can be ' 10111001 '.
In the 3rd embodiment of Fig. 4, when the type with the browser of terminal is updated to WAP 2.0, terminal uses browser type to generate the third terminal performance version with unique value through the current terminal capabilities information (that is, third terminal performance information) of upgrading.This third terminal performance version can be ' 0,101 1000 '.
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 easily determining terminal based on the terminal capabilities version of terminal changes.
In the present invention, (for example utilizing Session initiation Protocol (SIP) signaling message, select message, invitation message etc.) when coming the terminal capabilities information of exchange termination, or at call setup (for example, 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 exchanges exists in each terminal with the terminal capabilities information that exchanges 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 service connection, if based on the comparison, the terminal capabilities version that demonstrates the terminal B that is stored among the terminal A is different from the terminal capabilities version value of the current terminal B that receives of terminal A, then terminal A can notification terminal B: need to the terminal capabilities version of the terminal B that stored 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 in the situations such as dynamic change, the terminal capabilities version value of the terminal B that stores 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 for the maintenance 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 the method for LBS to another terminal with the common user ID in the memory cell that is stored in this terminal.
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 be in Fig. 1 and 3 system and device in or in similar or suitable device/system, realize.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 the second business, the system that utilizes the terminal capabilities version to carry out composite service can comprise first terminal 100 and the second terminal 200, when connecting for the first business, described first terminal 100 and the second terminal 200 exchange their terminal capabilities version each other.Each terminal compares the terminal capabilities version of another terminal of the receiving terminal capabilities version with this another terminal of having stored, if two terminal capabilities versions are different, and the terminal capabilities information of then upgrading to the described terminal request that is used for receiving.
This system also can comprise for the first business network that described the first business is provided to first terminal 100 and the second terminal 200, and the second business network that is used for providing to first terminal 100 and the second terminal 200 described the second business.When this first business was based on the business (professional such as IMS) of SIP, this first business network can comprise for the IMS core network 410 that the IMS business is provided to first terminal 100 with for the 2nd IMS core network 420 that the IMS business is provided to the second terminal 200.When described the second business is the CS business, this second business network for the CS core network that the CS business is provided to first terminal 100 (for example can comprise, among Fig. 1 31) and be used for providing to the second terminal 200 the 2nd CS core network (for example, 32 among Fig. 1) of CS business.This system also can comprise other parts, such as the first and second PS core networks, the first and second xRAN, the 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 the formerly service connection of other terminal obtain) 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 for the 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 based on this comparative result selectivity that terminal capabilities exchange is processed and service connection is set up processing.
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, then model IMS session sets up the embodiment of the method that CS calls out.The method also is applicable to only set up the IMS session, does not namely set up the situation that CS calls out after setting up the IMS session.
As shown in Figure 5, first terminal 100 and the second terminal 200 utilize composite service (for example, current CSI service connect) to exchange each other their terminal capabilities information and in respectively the terminal capabilities information that exchanges being stored in thereafter the cache memory of each terminal for example.First terminal 100 and the second terminal 200 are for example stored respectively 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 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 such as supported coding decoder, file format etc.In addition, each in first terminal 100 and the 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 the second terminal is.
Then, first terminal 100 be connected terminal 200 and utilize current sessions for CSI service/connections to carry out exchanges data and exchange of speech, and the subsequently current CSI session of release/connection (S52) between first terminal 100 and the second terminal 200.At this, first terminal 100 can store the common user ID of the second terminal 200, the terminal capabilities version of the second terminal 200 and the terminal capabilities information of the second terminal 200 therein, all these information are to set up in the process of processing at CSI to exchange, and first terminal 100 can also store the terminal capabilities version of himself therein.The second terminal 200 profits use the same method also can store this type of information relevant with the terminal capabilities information of first terminal 100.When first terminal 100 is wished with the 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, professional (for example in registration or cancellation IMS, PoC (Push to talk over Cellular), IM, broadcasting etc.), multimedia equipment dynamically is installed to first terminal 100 or removes, 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 with downloading service 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, now the current terminal capabilities version of first terminal 100 is different from the terminal capabilities version of this first terminal 100 in being stored in the 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 now current terminal capabilities version and the current terminal capabilities version (namely V.0.12) different (S55) that is stored in this first terminal 100 in the second terminal 200 of first terminal 100.
Thereafter, when first terminal 100 is wished with the second terminal 200 execution CSI service, the session connection that this first terminal 100 is attempted for the IMS business.Here, this first terminal 100 determines that it has stored the information relevant with the second terminal 200, and not in the situation of exchange terminal capabilities information, carries out the IMS session establishment by the transmission 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 generates to described the second terminal 200 with reference to the information that is stored in the second terminal 200 wherein.The information that is stored in the second terminal 200 in the first terminal 100 can comprise common user ID and the terminal capabilities information of the second terminal 200 at least.
Send invitation message (S56) from first terminal 100 to the second terminal 200 via an IMS core network 410 and the 2nd IMS core network 420.
The second terminal 200 obtains to be included in the terminal capabilities version of the first terminal 100 in the received invitation message.The second terminal 200 (for example, V.1.12) (for example, V0.12) compares the terminal capabilities version of the first terminal 100 that receives with the terminal capabilities version that is pre-stored in this first terminal 100 in the second terminal 200.The second terminal 200 is selected according to comparative result and is carried out that the terminal capabilities information exchange is processed and for one (S57) in the response transmission processing of IMS session connection request.
For example, if the terminal capabilities version of the first terminal that receives 100 is identical with the terminal capabilities version of the first terminal 100 of pre-stored, then the 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 received first terminal 100 is different from the terminal capabilities version of the first terminal 100 of pre-stored, then the 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 current performance information that the terminal capabilities information exchange processes to obtain first terminal 100.That is the terminal capabilities information after, the second terminal 200 selects request message (sip message) with the change of request first terminal 100 to first terminal 100 transmissions.Select request message can comprise the current terminal capabilities version of the second terminal 200.100 send and select request messages (S58) from the second terminal 200 to first terminal via an IMS core network 410 and the 2nd IMS core network 420.
Receive the first terminal 100 of selecting request message and send its terminal capabilities information to the second terminal 200.The terminal capabilities information of the new change of these the second terminal 200 these first terminals 100 of storage.Therefore, each in first terminal 100 and the second terminal 200 obtains and has stored current terminal capabilities information and the current terminal capabilities version of another terminal.
After, if necessary, first terminal 100 and the second terminal 200 can be carried out the CS call setup by the first and second CS core networks and process to provide CSI service.It is known that the CS call setup of CSI service is processed.
Therefore, when the terminal capabilities information of terminal changes, the terminal capabilities version can be retained as unique value, and be sent to subsequently the opposing party or more in many ways, whether the terminal capabilities information that can determine thus each terminal changes, then determines based on this, if terminal capabilities information changes, then can the requesting terminal performance information, stably use thus the memory cell of each terminal.Therefore the invention provides effectively a kind of and be used for efficiently composite service (for example, CSI) the system and method for exchange terminal capabilities information.
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 the 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 for to carry out the method for composite service, wherein, when this composite service was CSI service, model CS called out and sets up subsequently the IMS session.
Come execution in step S61 with the method identical with the method for the S51 that is used for Fig. 5 and S52.When the CSI service of having finished between first terminal 100 and the 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 the 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:
The second terminal; Bobs@lge.com; Text-audio-video-Motion Picture Experts Group (MPEG)-codec type etc.; V.3.3.
Wherein the second terminal 200 (for example, URI) common user ID is bobs@lge.com, but the support terminal performance information of the second terminal 200 represents text, audio frequency, video, Motion Picture Experts Group (MPEG) and various coding decoder, and V.3.3 the current terminal capabilities version of the second terminal 200 is.
After this, each in first terminal 100 and the second terminal 200 can dynamically change their terminal capabilities information in the situation of registration and cancellation IMS business, installation and removal multimedia device etc.As embodiment, below will describe for 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 formerly terminal capabilities version of first terminal 100 is, and V.1.12 the terminal capabilities version of newly-generated (through changing) is.
Subsequently, want model CS when first terminal 100 and call out when carrying out CSI service with the second terminal 200, first terminal 100 sends CS call setup messages (for example, setting up message) (S64) to the 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 the second terminal 200 via a CS core network 310 and the 2nd CS core network 320.
Then, the 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 the second terminal 200 at least.Can 100 send this connection message CONNECT from the second terminal 200 to first terminal 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 the 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 the second terminal 200 that receives when CS calls out compare (S66).According to this result relatively, first terminal 100 is selected and is carried out the terminal capabilities information exchange and process or select immediately and carry out the processing of IMS session establishment.
For example, in step S66, if the terminal capabilities version of the second terminal 200 of pre-stored is different from the terminal capabilities version of the second terminal 200 that receives, then first terminal 100 determines that the terminal capabilities version of the second terminal 200 since the CSI service of carrying out formerly variation has occured.Therefore, first terminal 100 is carried out terminal capabilities information exchange/transmission processing, wherein first terminal 100 selection request message from SIP to the second terminal 200 that send is with request and receive from the terminal capabilities information after the change of the second terminal 200 of the second terminal 200 (not shown among Fig. 6, but the selection that is similar to Fig. 2 is processed).
Yet, in step S66, if the terminal capabilities version of the second terminal 200 of pre-stored (for example, V.3.3) with the terminal capabilities version of the second terminal 200 of receiving (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 the second terminal 200 when carrying out CSI service formerly is identical.That is, the terminal capabilities information of the second terminal 200 does not change.Therefore, the selection request message that first terminal 100 does not send for terminal capabilities information to the second terminal 200, but to 200 transmissions of the second terminal it is set up the invitation message (S67) of IMS session.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 the second terminal 200.
Then the second terminal 200 will utilize the terminal capabilities version of the 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 the second terminal 200.For example, the second terminal 200 sends the terminal capabilities information request of first terminals 100 or about the response of IMS session connection request to first terminal 100.
Namely, in step S68, if the terminal capabilities version of the first terminal that receives 100 is identical with the terminal capabilities version of the 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 the first terminal that receives 100 is different from the terminal capabilities version of the 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 from terminal capabilities information from CSI service formerly.In other words, the second terminal 200 terminal capabilities information of determining first terminal 100 changes.Therefore the terminal capabilities information (S69) after the second terminal 200 selects request message with the change of asking thus first terminal 100 to first terminal 100 transmissions.Here select request message can comprise the terminal capabilities version of the second terminal 200.
Receive the first terminal 100 of selecting request message and then utilize the terminal capabilities information of selecting after response message sends it and changes to the second terminal 200, thereby so that the second terminal 200 can obtain the current performance information for the first terminal 100 of CSI service.
Therefore, the second terminal 200 is stored terminal capabilities information after the change of first terminal 100 and the performance version of this first terminal 100 corresponding with the terminal capabilities information after the change of first terminal 100 therein.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 the first terminal 100 in the second terminal 200.
Subsequently, process the IMS session of setting up between first terminal 100 and the second terminal 200 by known IMS session establishment, and between the two, exchange real data (media) (S70).
In step S64, if comprised the terminal capabilities version of first terminal 100 to the CS call setup message of the second terminal 200, then the second terminal 200 can compare the performance version of the first terminal 100 that the receives performance version with the first terminal 100 of having stored, and can the execution performance information exchange process (if version is different) or directly carry out IMS session establishment processing (if version is identical).
Therefore, each in first terminal 100 and the second terminal 200 is used at least unique terminal capabilities version of another terminal that the current terminal capabilities information based on another terminal generates.This has prevented the inconsistent problem between the terminal capabilities information of the terminal capabilities information that receives and pre-stored, and has simplified the signaling that connects for composite service and processed.In addition, owing to just carry out terminal capabilities information exchange/transmission processing in the terminal capabilities version that only ought the receive situation different from the terminal capabilities version of the corresponding terminal of pre-stored, so reduced network burden and CSI service is processed effective and efficiently.
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 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 in the situation of identical URI a user, also can generate based on the terminal capabilities information of each terminal the different terminals performance version with unique value.
Therefore, according to the present invention, each terminal 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 subsequently the terminal capabilities information exchange and process, 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 process.
Yet, in the present invention, if there is variation in the terminal capabilities version during call setup and session establishment, the particular side (that is, Calling Side or receiver side) that then receives the terminal capabilities version of opposite side compares to determine whether this terminal capabilities information changes with the terminal capabilities version of reception and the terminal capabilities version of pre-stored.Therefore, can solve the problem of the prior art 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 for when when carrying out composite service between first user and the second user at least and the 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 as mentioned above method of unique 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 executive basis composite service of the present invention, first user uses first terminal 100, and the 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 the execution graph 7 and 8, when composite service was CSI service, model CS called out, and set up the IMS session thereafter.In addition, in the method for Fig. 7 and 8, the second user has preset and has been used for the call forwarding function of Call Direrting to 2-2 terminal 220.In this embodiment, the terminal capabilities Information invariability of each during CSI service in 2-1 terminal 210 and the 2-2 terminal 220, and first terminal 100 dynamically upgrades its terminal capabilities information.Can have other situation, and the present invention also can be applicable to described other situation equivalently.
The first terminal 100 of supposing first user has been carried out the CSI service with the 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 the second user's 2-2 terminal 220.
Subsequently, first terminal 100 and the second user's 2-1 terminal 210 is carried out CSI service.Therefore, also stored common user ID, terminal capabilities information and the terminal capabilities version (S71) that connects another terminal that exchanges during setting up at CSI service at first terminal 100 in user's each of 2-1 terminal 210 with being connected.
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 therein this type of information relevant with 2-2 terminal 220.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 in the situation in conjunction with aforesaid common user ID and/or private subscribers ID, based on the performance version of terminal capabilities Information generation terminal 210 and terminal 220, so each performance version (value) is unique.
Subsequently, when the terminal capabilities information of first terminal 100 owing to for example first terminal 100 connects or dismantles from it multimedia device (such as video camera) when changing, first terminal 100 generates unique terminal capabilities version (S72) again with the terminal capabilities information of its change at least.Here, the terminal capabilities version of newly-generated first terminal 100 for example is 10000101.
When the 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, terminal 210 compares the version of the terminal capabilities version of the first terminal 100 that receives with formerly storage to determine.Terminal capabilities information (S73) after 2-terminal 210 then selects the request such as request and reception from the change of this first terminal 100 of first terminal 100 such as utilization.
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, the 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 thus call forwarding function set information (information that is associated with this call forwarding function).
After this, when first terminal 100 was wished with the 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 the 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 the second user's 2-2 terminal 220.
