From this embodiment content as can be seen, the embodiment of the invention is because outside the session that is activated of application server according to the session transfer request message transfers injection frequency terminal that receives, also further provide the reference information that shifts another session to the injection frequency terminal, promptly increased and informed the step of injection frequency terminal about the reference information that shifts another session, therefore the reference information of injection frequency terminal another session of transfer that just can provide according to described application server, to another session for example is that the 2nd session handled, thereby avoid prior art only to provide normal flow and the defective of unusual flow process is not provided, the flow process that makes session handle is more perfect, and application is stronger.
Fig. 2 is the conversation processing method flow chart of the embodiment of the invention two, mainly comprises step:
The reference information of another session of transfer that provides after the session that is activated of application server according to the described injection frequency terminal of session transfer request message transfers is provided for step 201, injection frequency terminal;
Step 202, described another session is handled according to described reference information.
Described reference information comprises: mobile switching centre supports or does not support the information of MAM characteristic, the information that indication injection frequency terminal used or do not use the MAM characteristic, or the information of the transfering state of described another session, described transfering state comprises and shifts successfully or shift failure.
The injection frequency terminal receives application server and also comprised before the reference information of another session of transfer that the injection frequency terminal provides: described injection frequency terminal sends to described application server and subscribes to the information that mobile switching centre supported or do not support the MAM characteristic, or the request message of the information of the transfering state of described another session.
Described method also comprises: described injection frequency terminal carries out radio frequency and switches; Described injection frequency terminal if not, then carries out radio frequency again and switches carrying out judging whether to receive the reference information of described another session of transfer before radio frequency switches behind the reference information of receiving described another session of transfer.
Described injection frequency terminal is carrying out judging whether that the reference information of receiving described another session of transfer comprises before radio frequency switches:
Described injection frequency terminal is carrying out judging the reference information of whether receiving described another session of transfer in the setting-up time before radio frequency switches.
Embodiment two and embodiment one have essentially identical result.In addition, the injection frequency terminal it is also conceivable that various different situations, be arranged on the reference information of receiving described another session of transfer in the setting-up time after, carry out radio frequency and switch, therefore use more flexible.
Carry out more detailed introduction below in conjunction with three to embodiment five pairs of embodiment of the invention of embodiment.
In the prior art,, can support the MAM characteristic by default MSC Server because UE can not be known the MAM characteristic of MSC Server.When UE carried out about the session processing procedure, following situation can appear:
1, when the Gm reference point does not keep, UE can't know whether the 2nd PS session shifts success from network side, and at this moment UE can give tacit consent to successfully transfer.If MSC Server does not support the MAM characteristic so, then can occur among the UE in fact only having 1 CS session among the MSC for the user shows 2 CS sessions, the phenomenon that the user can't connect the 2nd session appears like this.
2, when the Gm reference point keeps, UE thinks that the 2nd session changed the CS network over to, then can initiate the process of deletion PS session by the Gm reference point that keeps, this moment, SCC AS can successfully handle the request of deletion medium, therefore can return the 200OK acknowledge message, UE can think that the 2nd session shift successfully like this, so same occur with above-mentioned 1 in the problem described.
The technical scheme of the embodiment three to embodiment five that below provides provides the reference information that shifts another session by network side to the injection frequency terminal, comprises to the injection frequency terminal providing mobile switching centre to support or do not support the information of MAM characteristic; Perhaps, provide indicating terminal to use or do not use the information of MAM characteristic to the injection frequency terminal; Perhaps, provide the information of the transfering state of another session, can address the above problem to the injection frequency terminal.Be the convenience of describing, the said UE of following content refers to injection UE frequently.
Embodiment three:
UE subscribes to the transfering state of the 2nd session to SCC AS among the embodiment three, or MSC Server supports or do not support the information of MAM characteristic.
Fig. 3 is the conversation processing method flow chart of the embodiment of the invention three, mainly comprises step:
Step 301, UE-1 initiate to subscribe to the subscribe request message to SCC AS, require the transfering state of the 2nd related with UE in subscribed network session, or the MAM characteristic of MSC Server (support or do not support).
The incident Event that comprises in the subscribe request message is: second_session (transfering state of representing the 2nd session) or mam (the MAM characteristic of expression MSC Server).
In subscribe message, also comprise the Instance ID or the MSISDN that are used for related UE.Instance ID can be included in connection (contact) message header, and MSISDN then can comprise by first-selected identification (P-Preferred-Identity) head or request-universal resource identifier (Request-URI) message header.
Need to prove that this subscribe message can be carried out PS registration back at UE and be sent or send after UE sets up the 2nd PS session.
When UE subscribes to the transfering state of the 2nd session, know the transfering state of the 2nd session at SCC AS after, send Notify message to UE, can be only in the time can not shifting the 2nd session, to send Notify message, or the 2nd session transfer be that success or failure all send Notify message to UE to UE.
When UE subscribes to the MAM characteristic of MSC Server, follow-up SCC AS can known the MAM characteristic of MSCServer, when the MAM characteristic of perhaps knowing MSC Server changes, inform UE by Notify message, for example by the MAM characteristic of not knowing MSC Server to knowing that MSC Server supports or when not supporting the MAM characteristic, sending Notify message and inform UE.
Step 302, SCC AS return 200OK message to S-CSCF.
Follow-up different UEs is set up 2 PS voice conversations in the PS Access Network, the session between UE-1 and UE-2 (the 1st session) is in the active state, and the session between UE-1 and UE-3 (the 2nd session) is in the hold state.And each UE is current to be in the LTE network, follow-up will switching in universal mobile telecommunications system (UMTS, the Universal Mobile Telecommunications System) network.
Step 303, MSC Server generate the Invite request message, send to SCC AS by S-CSCF;
The LTE network measuring dies down to the LTE signal strength signal intensity of UE, then sends transfer request message to MSC Server.MSC Server generates the Invite request message and sends to SCCAS by S-CSCF after receiving transfer request message, and request is transferred to the CS network with voice conversation.
The called number of this Invite request message association is STN-SR (Session Transfer Number-Single Radio), and this called number is used for indication and initiates single-frequency Single Radio transfer.In this Invite request message, comprise Instance ID or the MSISDN of UE-1 in addition, also comprise the indication that MSC Server does not support the MAM characteristic.
After step 304, SCC AS receive this Invite request message, know that according to STN-SR SCC AS has carried out transfer, send the re-Invite request message, be used to inform that UE-2 is connected to MSC Server with medium to opposite end UE-2.
Step 305, UE-2 return 200OK message to SCC AS.
Step 306, SCC AS return 200OK message to MSC Server.
Because MSC Server does not support the MAM characteristic, therefore in this 200OK message, do not comprise the media information of session between UE-1 and UE-3.
Step 307, MSC Server are that UE-1 distributes the CS Radio Resource, and send to UE-1 by the LTE network.
Step 308, SCC AS inform that to UE-1 the 2nd session do not shift or inform that MSC Server does not support the MAM characteristic by notice Notify message.
Instance ID or MSISDN that SCC AS comprises according to subscribe request message in the step 301, Instance ID that the Invite request message comprises in the step 303 or MSISDN and MSC Server do not support the indication of MAM characteristic, know that the MSC Server at UE-1 place does not support the MAM characteristic.Therefore SCC AS is in Notify message, indicate the 2nd session not shift or instruct MS C Server does not support the MAM characteristic, Notify message comprises above-mentioned information by the message body of extend markup language (XML, Extensible Markup Language) form.
If the transfering state of the 2nd session of indication in Notify message then comprises in following one or multinomial in message body:
1) session identification of the 2nd session (dialog ID);
2) whether the 2nd session shifts success, for example is Transferred or Not_transferred, and wherein Transferred represents that the 2nd session successfully shift, and Not_transferred represents that the 2nd session do not shift, and promptly shifts failure.
The embodiment of XML form is as follows:
(Schema) is as follows in the plan of XML message body:
If whether indication MSC Server supports the MAM characteristic in Notify message, then in message body, comprise in following one or multinomial:
1) description of target network element, as: MSC Server etc.
2) whether supporting the description of MAM characteristic, for example is supported, unsupported, and unknown etc., wherein supported represents that MSC Server supports the MAM characteristic; Unsupported represents that MSC Server does not support the MAM characteristic; Unknown represents not know whether MSC Server supports the MAM characteristic, the main scene that this state uses is, when UE does not carry out IMS when registration by MSC Server, SCC AS does not know within the current control that is in which MSC Server of this UE, so state is unknown.
The embodiment of XML form is as follows:
The Schema of XML message body is as follows:
Step 309, UE-1 carry out different disposal according to the content of Notify message, and return 200OK message to SCC AS.
Whether UE-1 sets up the state machine of the 2nd session according to the content decision-making of Notify message.If know that success is shifted in the 2nd session or MSC Server supports the MAM characteristic, then set up the state machine of the 2nd session, otherwise do not set up.
Need to prove, above-mentioned steps 304,307,308 do not have a sequencing.
Step 310, UE-1 switch to new radio frequency according to assigned radio resource.
UE-1 judges the Notify message whether receive SCC AS in setting-up time before switching to new radio frequency, if not, then receive to carry out after the Notify message in this setting-up time again and switch.If surpass setting-up time, do not receive yet Notify message or since fast switching do not receive Notify message, then carry out radio frequency and switch, and carry out following processing:
If what subscribe to is the transfering state of the 2nd session, UE gives tacit consent to the 2nd session and shifts successfully.If what subscribe to is the MAM characteristic of MSC Server, if so the MAM characteristic of having informed MSC Server before the SCC AS, then UE is according to the result treatment of preserving, otherwise supports the MAM characteristic to handle according to MSC Server.
Need to prove that just illustrate to receive Notify message, other message also are similar processing here.
Need to prove,, then carry out following steps 311-312 if the Gm reference point keeps, otherwise execution in step 313.
Step 311, UE-1 send re-Invite message or Bye message by new PS network to SCC AS, the PS voice medium between request deletion and UE-1 and UE-2.
Step 312, SCC AS return 200OK message to UE-1.
Step 313, SCC AS send re-Invite message or Bye message to UE-3, the PS voice medium between request deletion and UE-1 and UE-3.
Step 314, UE-3 return 200OK message to SCC AS.
From this embodiment content as can be seen, because UE has subscribed to the transfering state of the 2nd session or the MAM characteristic of MSC Server to SCC AS, therefore SCC AS can be in the session processing procedure, the transfering state of the 2nd session or the MAM characteristic of MSC Server are informed UE by Notify message, UE just can know whether MSC Server supports the MAM characteristic so, know perhaps whether the 2nd session shifts success, UE just can carry out different disposal according to different situations like this, thereby when avoiding in the prior art because the transfer success of the 2nd session of acquiescence or default MSC Server support the MAM characteristic that actual conditions are opposite, the problem that can't connect the 2nd session of appearance.
Embodiment four:
Embodiment four is that with the main distinction of embodiment three SCC AS initiatively informs to UE whether transfering state, the MSC Server of the 2nd session support whether MAM characteristic or indicating terminal use the MAM characteristic.
Hypothesis MSC Server does not support the MAM characteristic among the embodiment four, UE is current to set up 2 PS voice conversations in the PS Access Network, session between UE-1 and UE-2 (the 1st session) is in the active state, and the session between UE-1 and UE-3 (the 2nd session) is in the hold state.And each UE is current to be in the LTE network follow-up will switching in the UMTS network.
Fig. 4 is the conversation processing method flow chart of the embodiment of the invention four, mainly comprises step:
Step 401-405, identical with step 303-307 among the embodiment two is specifically referring to the description among the embodiment.
Step 406, SCC AS initiatively inform that to UE-1 the 2nd session do not shift or inform that MSC Server does not support the MAM characteristic.
Instance ID that SCC AS comprises according to Invite request message in the step 401 or MSISDN and MSC Server do not support the indication of MAM characteristic, know that the MSC Server at UE-1 place does not support the MAM characteristic.Therefore SCC AS initiatively sends message to UE-1, informs that the 2nd session do not shifted or MSC Server does not support the MAM characteristic, is specially:
Can send to UE by operation strategy Operator Policy and inform information, inform in Operator Policy message whether UE uses the MAM characteristic.Can determine that indication UE uses or do not use the MAM characteristic according to the information of the transfering state of the information of the MAM characteristic of MSC or second session.For example, if MSC does not support MAM characteristic or second session to shift failure, then SCC AS informs that UE does not use the MAM characteristic in the Operator Policy that sends to UE;
Inform that by heavily asking re-Invite message, renewal Update message, cell Info message or information Message message the 2nd session of terminal do not shifted or MSC Server does not support the MAM characteristic.
These message comprise above-mentioned information by the message body of XML form.The concrete form of message body is with the description among the embodiment three.
Step 407, UE-1 carry out different disposal according to the content in the message that receives, and return 200OK message to SCC AS.
UE-1 makes a strategic decision whether set up the state machine of the 2nd session according to step 406.Shift successfully or require to use MAM characteristic or MSC Server support MAM characteristic if know the 2nd session, then set up the state machine of the 2nd session, otherwise do not set up.
Step 408, UE-1 switch to new radio frequency according to assigned radio resource.
UE-1 judges message or the Operator Policy whether receive that in setting-up time SCC AS sends before switching to new radio frequency, if not, then receive to carry out behind message or the Operator Policy in this setting-up time again and switch.If surpass setting-up time, do not receive message or Operator Policy yet, perhaps, then carry out radio frequency and switch, and carry out following processing because message or Operator Policy are not received in quick switching:
If what need issue is the transfering state of the 2nd session, UE gives tacit consent to the 2nd session and shifts successfully when not receiving this content.If what need issue is the MAM characteristic of MSC Server, when not receiving this content, if so the MAM characteristic of having informed MSC Server before the SCC AS, then UE is according to the result treatment of preserving, otherwise supports the MAM characteristic to handle according to MSC Server.
Step 409-412, identical with step 311-314 among the embodiment three is specifically referring to the description among the embodiment.
From this embodiment content as can be seen, because SCC AS can be in the session processing procedure, active is with the transfering state of the 2nd session, whether whether terminal use MAM characteristic or MSC Server to support the MAM characteristic to inform UE by various different messages, UE just can know whether MSC Server supports the MAM characteristic so, whether terminal uses the MAM characteristic, know perhaps whether the 2nd session shifts success, UE just can carry out different disposal according to different situations like this, thereby when avoiding in the prior art because the transfer success of the 2nd session of acquiescence or default MSC Server support the MAM characteristic that actual conditions are opposite, the problem that can't connect the 2nd session of appearance.
Embodiment five:
Embodiment five switches under the situation that new radio frequency and Gm reference point keep at UE, sends response message to UE after detecting the transfering state of the 2nd session, initiatively the MAM characteristic of informing the transfering state or the MSC Server of the 2nd session to UE.
Hypothesis MSC Server does not support the MAM characteristic among the embodiment five, UE is current to set up 2 PS voice conversations in the PS Access Network, session between UE-1 and UE-2 (the 1st session) is in the active state, and the session between UE-1 and UE-3 (the 2nd session) is in the hold state.And each UE is current to be in the LTE network follow-up will switching in the UMTS network.
Fig. 5 is the conversation processing method flow chart of the embodiment of the invention five, mainly comprises step:
Step 501-505, identical with step 303-307 among the embodiment three is specifically referring to the description among the embodiment.
Step 506, MSC Server are that UE-1 distributes the CS Radio Resource, and send to UE-1 by the LTE network.
Step 507, UE-1 enter new PS network according to assigned radio resource, send re-Invite message or Bye message by new PS network to SCCAS, the PS voice medium between request deletion and UE-1 and UE-2.
Step 508, SCC AS return 200OK message to UE-1.
Step 509, UE-1 send re-Invite or Bye message by new PS network to SCC AS, the PS voice medium between request deletion and UE-1 and UE-3.
Because UE-1 do not know whether the MAM characteristic of MSC Server or the 2nd session shift success, so UE-1 gives tacit consent to the 2nd session and shifts successfully, then by new PS network to SCC AS transmission re-Invite or Bye message.
Step 510, SCC AS know that the re-Invite message of UE-1 initiation or the purpose of Bye message are to shift the 2nd session, and whether therefore detecting the 2nd session shifts success, returns response message according to testing result to UE-1.
Do not shift success if detect the 2nd session, SCC AS returns error response message to UE-1, and this error response message can be message such as 403 message, 503 message or 603.
Optionally, in error response message, comprise reason reason message header or call information Call-Info message header, be used to inform the reason of UE mistake, for example:
When using the reason message header:
Failure is shifted in the 2nd session, and at this moment the content of reason message header is:
Reason：SIP；cause＝400；text＝″second?session?not?transfer″
Or indicating terminal does not use the information of MAM characteristic
Reason：SIP；cause＝400；text＝″not?using?mam″
Or MSC Server do not support the MAM characteristic, and at this moment the content of reason message header is:
Reason：SIP；cause＝400；text＝″mam?is?unsupported″
When using the Call-Info message header:
Failure is shifted in the 2nd session, and at this moment the content of Call-Info message header is:
Call-Info：Second-Session-indication；purpose＝Second_Session_failed
Or indicating terminal does not use the information of MAM characteristic
Call-Info：MAM-indication；purpose＝Not_Using
Or MSC Server do not support the MAM characteristic, and at this moment the content of Call-Info message header is:
Call-Info：MSC-Server；purpose＝MAM_unsupported
Above-mentionedly can determine that indication UE uses or do not use the MAM characteristic according to the information of the transfering state of the information of the MAM characteristic of MSC or the 2nd session.
Shift successfully if detect the 2nd session, SCC AS returns success response message to UE-1.Step 511, UE-1 carry out different disposal according to the content of Notify message, and return 200OK message to SCC AS.
Whether UE-1 sets up the state machine of the 2nd session according to the content decision-making of response message.If know that success is shifted in the 2nd session or MSC Server supports the MAM characteristic, then set up the state machine of the 2nd session, otherwise do not set up.
Step 512, SCC AS send re-Invite message or Bye message to UE-3, the PS voice medium between request deletion and UE-1 and UE-3.
Step 513, UE-3 return 200OK message to SCC AS.
From this embodiment content as can be seen, SCC AS switches under the situation of new radio frequency and the reservation of Gm reference point at UE, send response message to UE after detecting the transfering state of the 2nd session, the MAM characteristic of initiatively informing the transfering state or the MSC Server of the 2nd session by response message to UE, UE just can know whether MSC Server supports the MAM characteristic so, know perhaps whether the 2nd session shifts success, UE just can carry out different disposal according to different situations like this, thereby when avoiding in the prior art because the transfer success of the 2nd session of acquiescence or default MSC Server support the MAM characteristic that actual conditions are opposite, the problem that can't connect the 2nd session of appearance.
