Description
Technical field
The present invention relates to communication technical field, particularly a kind of processing call holding voice, system and device.
Background technology
The ability that VCC (Voice Call Continuity, continuous voice call) technology provides voice to shift between CS (Circuit Switched, circuit switching) territory and IMS (IP Multimedia Sub-system, IP Multimedia System) territory.The core of VCC is VCC AS (Application Server, application server), be called application server for continuity of voice call, finish the handoff functionality between circuit domain call branch and IP-CANVoIP (Voice over Internet Protocol, the ip voice is called out) calling branch.
Calling that the user is all or session must be through the VCC AS in IMS territory, for the switching controls in follow-up territory is prepared.VCC user will be routed to VCCAS from the calling of CS initiation and the voice conversation of initiating from the IMS territory, sends to the callee then; Equally, mail to VCC user's calling or session, also will be routed to VCCAS.
When the Access Network at the current place of user is only supported the CS audio call, and when not supporting VoIP.The user initiates an audio call, and this is called out by the CS network and initiates, and this calling is routed to VCC AS, and VCC AS sends to the opposite end with this calling after handling.When the user moves to the network of a support VoIP, need switch to PS (Packet Switch from the CS network this moment with voice call, packet switching) network, user's UE can initiatively initiate a VoIP request by the PS network, this request can arrive VCC AS, VCC AS control switches to the PS territory with the CS signalling path between VCC AS and initiator, and the signalling path of VCC AS and opposite end remains unchanged.Because the existence of VCC AS, make the user when CS and PS network switch, the benefit of VCC business that Here it is is experienced and impression in the conversation that can not influence distant terminal.
IMS (IP Multimedia Sub-system, IP Multimedia System) is based on IP (InternetProtocol, Internet Protocol) network is the network of a more complicated, because the IMS terminal that all CS network users can not more renew at short notice, therefore, the CS network will be network coexisted in regular period and IMS, and so, two business platforms of CS and IMS are runed simultaneously can increase operation cost.Further, if introduce a new business, CS and two business platforms of IMS need be reconstructed by operator, will certainly increase construction cost.Therefore, the function of CS network business platform need be transferred to the IMS network, to realize the unification of business platform, the unification of business platform is called ICS (IMS Centralized Service, the control of IMS centralized traffic).
ICS requires to realize that UE sets up IMS by CS network carrying voice medium and calls out, and by the AS among the IMS business being carried out in calling provides; CS carrying is called out and is realized by setting up CS between UE and new ICCF (IMS CallControl Function, the IMS CCF) unit of introducing, simultaneously, weakens or removes business processing logic among the MSC; UE is by new ICCC (the IMS CS ControlChannel that introduces, IMS circuit domain access control function) transmitting-receiving IMS calls out relevant control signaling, ICCC may pass through USSD (Unstructured Supplementary Services Data, unstructured supplementary data traffic) or PS (Packet Switching, packet switching) carrying.USSD is a kind of message communicating mechanism of CS network.Fig. 1 is the Organization Chart of ICS.
Among Fig. 1, MGCF (Media Gateway Control Function, MGCF)/MGW (Media Gateway, media gateway) is the equipment of CS network and IMS network interworking, is responsible for the conversion of signaling and medium respectively.
As shown in Figure 2, call out the flow chart that keeps (hold) process for ICS UE, (the Serving-Call Session Control Function of S-CSCF among the figure, service call conversation control function) and ICCF, TAS (Telephony Application Server, telco application server) belongs to the home network of UE-A.The S-CSCF of UE-B home network, ICCF (IMS Call Control Function, IMS CCF) and TAS omit.This ICS UE calls out the maintenance process and supposes that ICS user UE-A has set up voice with UE-B and has been connected, and UE-A need carry out the Hold supplementary service, specifically comprises:
S201, UE-A initiates the hold service request by the ICCC channel to ICCF.
S202～S205, ICCF initiate to keep the service request of current calling after receiving this hold request to MGCF by re-Invite/Update message.
S206～S213, ICCF initiates the hold request to UE-B, and this hold request is through TAS, and the effect of TAS is exactly to carry out the hold supplementary service in the IMS territory.
S214, TAS sets up and being connected of UE-B by MRFC (Media Resource Funtion Controller, Multimedia resource function controller (MRFC)) control MRFP (Media Resource Funtion Processor, Multimedia resource function processor (MRFP)).
S215, MRFP sends Announcement (call hold tone) to UE-B.
Illustrate: MRFP is put call hold tone multiple mode, except method shown in Figure 2, can also be that MRFP is inserted into and puts call hold tone in the bearing link, promptly bearer path be UE A-vMSC (visitedMobile Switch Center visits mobile interaction center)-MGW-MRFP-UE B; Can also to be UE-B in addition download call hold tone by a network address to the network pronounces.Here only listed a kind of mode of playback.
So far, ICS user UE-A carries out the hold EO.
As shown in Figure 3, for non-ICS user passes through Camel (Customized Application for MobileNetwork Enhanced Logic, the customization application of mobile network's enhanced logic) flow chart of the hold process of access ICS network, S-CSCF and ICCF among the figure, TAS belongs to the home network of UE-A.The S-CSCF of UE-B home network, ICCF and TAS do not omit and draw, this non-ICS UE calls out the maintenance process and supposes that non-ICS user UE-A has set up voice with UE-B and has been connected, UE-A need carry out the Hold supplementary service, since non-ICS user do not have in the CS territory the ICCC channel (for example: USSD), therefore the hold request can only be transmitted by the CS domain signaling, specifically comprises:
S301, UE-A make a call to vMSC by the hold signaling in the CS territory and keep request.
After S302, vMSC receive this order, send CPG (Call ProGress, calling procedure) signaling to MGCF, the parameter of this signaling is hold, is used to indicate MGCF to carry out and calls out the maintenance supplementary service.
S303, MGCF translate into SIPre-Invite/Update message with circuit domain signaling after receiving CPG (hold) signaling, and a of the SDP of this message is capable, and form is as follows: a=sendonly, this a is capable to be used to indicate UE-B to carry out the hold operation.
S304, S-CSCF gives ICCF with this forwards.
S305, ICCF carries out the function of B2BUA (Back to Back User Agent, back-to-back user agent), generates new re-Invite/Update message, and this message is sent to S-CSCF.
S306, S-CSCF gives TAS with this forwards.
After S307, TAS receive this re-Invite/Update message,, know to call out to keep supplementary service (hold), and carry out corresponding hold and handle (step S315), and this message is sent to S-CSCF according to the capable information of a of this message.
S308, S-CSCF gives this forwards to end subscriber UE-B.
S309～S314, UE-B returns acknowledge message.
S315, TAS sets up and being connected of UE-B by MRFC control MRFP.
Wherein, step S307 and step S315 can carry out simultaneously.
S316, MRFP sends Announcement (call hold tone) to UE-B.
S317 because vMSC has carried out the hold supplementary service, therefore sends the maintenance sound to UE-B.
VCC user inserts the hold process of ICS network, and is the same with situation shown in Figure 3, no longer repeats here.
In realizing process of the present invention, the inventor finds that prior art exists following shortcoming: TAS whether can't judge the CS network for providing call hold tone to end subscriber at least, TAS can carry out hold Business Processing process after receiving the hold request in the IMS network, to end subscriber is play call hold tone.Therefore, will cause CS network and IMS network, cause the wasting of resources and make the end user experience variation simultaneously to end subscriber is put call hold tone.

Embodiment
The embodiment of the invention provides a kind of processing call holding voice, TAS judges whether that according to the content of the hold business request information that receives needs are to providing call hold tone to end subscriber, thereby avoided CS network and IMS network to repeat to have saved Internet resources to providing call hold tone to end subscriber.
As shown in Figure 4, the flow chart for embodiment of the invention processing call holding voice specifically may further comprise the steps:
Step S401, TAS receive CS and insert the hold business request information that IMS network control entity sends.Alternatively, before the hold business request information is sent to TAS, CS inserts IMS network control entity, for example ICCF entity or VCC AS judge the CS network whether for providing call hold tone to end subscriber, and add the hold indication information according to this judged result in the hold business request information.The CS that the embodiment of the invention is mentioned inserts IMS network control entity and is used for the calling of CS initiation is inserted the IMS network, finishes the function of B2BUA, can be VCC AS or ICCF entity.
Step S402, whether TAS determines according to the content of hold business request information and carries out to providing call hold tone to end subscriber.For example: comprise in judging the hold business request information and call out the maintenance message header, for example: after the P-Access-Network-Info, TAS is for providing call hold tone to end subscriber.In addition, TAS can also insert IMS network control entity according to CS, and for example judge whether need be for providing call hold tone to end subscriber for the hold indication information that adds in the hold business request information of ICCF entity or VCC AS.
As shown in Figure 5, flow chart for the embodiment of the invention one, when VCC user initiates the hold request, TAS judges whether the situation that comprises of P-Access-Network-Info by the hold business request information need be for providing call hold tone to end subscriber, and supposition VCC user UE-A exists voice to be connected with user UE-B in the CS territory.Specifically may further comprise the steps:
Step S501, UE-A make a call to vMSC by the hold signaling in the CS territory and keep request.
After step S502, vMSC receive this order, send the CPG signaling to MGCF, the parameter of this signaling is hold, is used to indicate MGCF to carry out and calls out the maintenance supplementary service.
Step S503, after MGCF receives CPG (hold) signaling, circuit domain signaling is translated into SIP (Session Initial Protocol, session initiation protocol) re-Invite/Update message, the SDP of this message (Session Description Protocol, Session Description Protocol) a is capable, and form is as follows: a=sendonly, the capable indication execution hold business that is used for of this a.
Step S504, S-CSCF sends to VCC AS with this re-Invite/Update message.
Step S505～step S506, VCC AS sends to TAS with re-Invite/Update message by S-CSCF.
Step S507, after TAS receives re-Invite/Update message, judge whether this re-Invite/Update message comprises the P-Access-Network-Info header field, if comprise this header field, illustrate that this re-Invite/Update message comes from the PS network, need be for providing call hold tone to end subscriber; If do not comprise the P-Access-Network-Info header field in this re-Invite/Update message, illustrate that then this re-Invite/Update message comes from the CS network, and the CS network does not need TAS again for providing call hold tone to end subscriber for providing call hold tone to end subscriber.In embodiment one, the hold business request information comes from the CS network, so does not comprise the P-Access-Network-Info header field in the re-Invite/Update message, so TAS does not need for providing call hold tone to end subscriber.
Step S508, the re-Invite/Update message after TAS will upgrade sends to the UE-B of opposite end by S-CSCF.
Step S509～step S514, UE-B returns confirmation to end subscriber.
Step S515, vMSC begin to put call hold tone.
As shown in Figure 6, flow chart for the embodiment of the invention two, when VCC user initiates the hold request, whether VCC AS needs for providing call hold tone to end subscriber by the amendment advice TAS to the hold business request information, and supposition VCC user UE-A exists voice to be connected with user UE-B in the CS territory.Specifically may further comprise the steps:
Step S601, UE-A make a call to vMSC by the hold signaling in the CS territory and keep request.
After step S602, vMSC receive this order, send the CPG signaling to MGCF, the parameter of this signaling is hold, is used to indicate MGCF to carry out and calls out the maintenance supplementary service.
Step S603, after MGCF receives CPG (hold) signaling, circuit domain signaling is translated into SIP (Session Initial Protocol, session initiation protocol) re-Invite/Update message, the SDP of this message (Session Description Protocol, Session Description Protocol) a is capable, and form is as follows: a=sendonly, the capable indication execution hold business that is used for of this a.
Step S604, S-CSCF sends to VCC AS with this re-Invite/Update message.
Step S605, VCC AS come from MGCF according to the hold business request information and judge the user and be in the CS network, and the CS network does not need TAS again for providing call hold tone to end subscriber for providing call hold tone to end subscriber; Therefore carry out the function of B2BUA, the re-Invite/Update request of backend steps S604, and generate new re-Invite/Update request.By the modification of re-Invite/Update message being notified TAS whether need for providing call hold tone to end subscriber, after receiving this re-Invite/Update message, whether TAS can judge by the content of this re-Invite/Update message needs for providing call hold tone to end subscriber.VCC AS is as follows to the concrete modification method of re-Invite/Update message:
Method one: with capable modification of a of the message body SDP of Invite message, for example: with the capable a=sendonly:CS that is revised as of a
Method two: in the message header of Invite message, increase P-Access-Network-Info, for example: P-Access-Network-Info:3GPP-GERAN; " CS "
Method three: in the message header of Invite message, increase a virtual Alert-Info or Call-Info message header.For example: Alert-Info=http: //CS.cs
Call-Info＝http://CS.cs
Step S606～step S607, VCC AS sends to TAS with amended re-Invite/Update message by S-CSCF.
Step S608, after TAS receives re-Invite/Update message, find to contain the message header shown in the S605 in steps in this re-Invite/Update message, know that the CS network for providing call hold tone to end subscriber, does not therefore need again for providing call hold tone to end subscriber.
Step S609, the re-Invite/Update message after TAS will upgrade sends to the UE-B of opposite end by S-CSCF.
Step S610～step S615, UE-B returns confirmation to end subscriber.
Step S616, vMSC begin to put call hold tone.
As shown in Figure 7, flow chart for the embodiment of the invention three, when ICS user initiates the hold request, TAS is by in the hold request message situation that comprises of P-Access-Network-Info header field is judged whether need be for providing call hold tone to end subscriber, and supposition ICS user UE-A exists voice to be connected with user UE-B in the CS territory.Specifically may further comprise the steps:
Step S701～step S702, UE-A keeps request by the ICCC channel in the CS territory (is example with the USSD) business of making a call.
Step S703, ICCF comes from the USSD channel according to the hold business request information, judge the CS network not for providing call hold tone to end subscriber, need TAS for providing call hold tone to end subscriber, therefore carry out the function of B2BUA, the re-Invite/Update request of backend steps S702, and generate new re-Invite/Update message.In this re-Invite/Update message, increase a P-Access-Network-Info, for example: P-Access-Network-Info:3GPP-GERAN; " I1-CS ".
Make a call for non-ICS user and to keep professional situation, ICCF comes from MGCF according to the hold service request and can judge the user and be in the CS network, and the CS network is for providing call hold tone to end subscriber, do not need TAS for providing call hold tone, therefore this re-Invite/Update message is not carried out any processing end subscriber.
Step S704～step S705, ICCF sends to TAS with amended re-Invite/Update message by S-CSCF.
Step S706, after TAS receives re-Invite/Update message, find to contain P-Access-Network-Info in this re-Invite/Update message, know that the CS network, therefore need be for providing call hold tone to end subscriber not for providing call hold tone to end subscriber.
Step S707, TAS sends to opposite end UE-B with re-Invite/Update message by S-CSCF.
Step S708～step S713, UE-B returns confirmation to end subscriber.
Step S714, TAS is put call hold tone by MRCF control MRFP to UE-B.
Step S715, MRFP begin to put call hold tone.
Illustrate: MRFP is put call hold tone multiple mode, except method shown in Figure 7, can also be that MRFP is inserted into and puts call hold tone in the bearing link, and this bearer path is UEA-vMSC-MGW-MRFP-UE B; Can also to be UE-B in addition download call hold tone by a network address to the network pronounces.Here only listed a kind of mode of putting call hold tone.
As shown in Figure 8, flow chart for the embodiment of the invention four, when non-ICS user initiates the hold request, whether ICCF needs for providing call hold tone to end subscriber by the amendment advice TAS to the hold business request information, and supposing that non-ICS user UE-A has set up voice with user UE-B and has been connected, UE-A need carry out the Hold supplementary service.Because non-ICS user do not have the ICCC channel, so the hold business request information can only transmit by the CS domain signaling, specifically may further comprise the steps:
Step S801, UE-A make a call to vMSC by the hold signaling in the CS territory and keep request.
After step S802, vMSC receive the hold signaling, send the CPG signaling to MGCF, the parameter of this signaling is hold, is used to indicate MGCF to carry out and calls out the maintenance supplementary service.
Step S803, MGCF translate into SIPre-Invite/Update message with circuit domain signaling after receiving CPG (hold) signaling, and a of the SDP of this message is capable, and form is as follows: a=sendonly, this a is capable, and the indication execution hold that is used for operates.
Step S804, S-CSCF sends to ICCF with this re-Invite/Update message.
Step S805, ICCF come from MGCF according to the hold business request information and judge the user and be in the CS network, and the CS network does not need TAS again for providing call hold tone to end subscriber for providing call hold tone to end subscriber; Therefore carry out the function of B2BUA, the re-Invite/Update request of backend steps S804, and generate new re-Invite/Update message.By notifying TAS whether to need to provide call hold tone to the modification of re-Invite/Update message, after receiving this re-Invite/Update message, whether TAS can judge by this re-Invite/Update message needs for providing call hold tone to end subscriber.
ICCF is as follows to the concrete modification method of re-Invite/Update message:
Method one: ICCF makes amendment to the message body SDP message of hold business request information, for example: with capable being revised as of a of SDP message: a=inactive; CS; Perhaps, a=inactive; I1-CS.Wherein, a=inactive; CS do not need to represent TAS to provide call hold tone, a=inactive; I1-CS need to represent TAS that call hold tone is provided.
Method two: ICCF makes amendment to the message header of hold business request information, increases the P-Access-Network-Info header field, for example:
P-Access-Network-Info:3GPP-GERAN; " CS ", perhaps,
P-Access-Network-Info：3GPP-GERAN；“I1-CS”。
Wherein, P-Access-Network-Info:3GPP-GERAN; " CS " expression does not need TAS to provide call hold tone, P-Access-Network-Info:3GPP-GERAN; " I1-CS " expression needs TAS that call hold tone is provided.
Method three: ICCF makes amendment to the message header of hold business request information, increases Alert-Info or Call-Info head, and the parameter of this two stature is a virtual address.For example:
(1)Alert-Info＝http://CS.cs
Call-Info＝http://CS.cs
(2)Alert-Info＝http://I1-CS.i1-cs
Call-Info＝http://I1-CS.i1-cs
Wherein, the alter mode of (1) do not need to represent TAS that call hold tone is provided, and the alter mode of (2) need to represent TAS for providing call hold tone to end subscriber.
Step S806～step S807, ICCF sends to TAS with amended re-Invite/Update message by S-CSCF.
After step S808, TAS receive re-Invite/Update message, judge whether that according to the particular content of re-Invite/Update message needs are for providing call hold tone to end subscriber.
Step S809, TAS sends to opposite end UE-B with re-Invite/Update message by S-CSCF.
Step S810～step S815, UE-B returns confirmation to end subscriber.
Step S816, vMSC begin to put call hold tone.
Above-mentioned processing call holding voice, TAS judges whether that according to the hold indication information in the hold business request information that receives needs provide call hold tone, thereby avoided CS network and IMS network to repeat to providing call hold tone to end subscriber, save Internet resources, also improved user's Experience Degree.
