Description
Technical field
The present invention relates to communication technical field, relate in particular to fulfillment capability negotiation method in integrated service.
Background technology
Development along with mobile communication technology, people no longer are satisfied with single voice communication mode, and multimedia communication mode that need be brand-new, this multimedia communication is not only simple video and audio communication, also comprise instant message, with the business that browses the location, business such as collaborative work, Streaming Media, particularly new traffic mode and traditional voice merge.Trend based on Internet and communication network fusion, each standardization body has proposed the notion of next generation network, on the packet carrying network basis, introduced the IP Multimedia System (IMS) of all-IP business network framework, the target of IMS is according to personalized user data, the shielding user mode access, the degree of opening of control professional ability provides multimedia communication experiences.
Topmost functional entity is controlling call entity (CSCF) and home subscriber server (HSS) among the IMS.CSCF has three types: serving CSCF (S-CSCF), proxy CSCF (P-CSCF), inquiry CSCF (I-CSCF).The IMS territory is based on the professional control domain on the packet carrying network, Signalling exchange between Packet Based Network carrying terminal and the P-CSCF, P-CSCF is IMS terminal first contact point at the IMS network, finish agent functionality, carry out the IMS Signalling exchange with terminal, carry out inter-process and then it is transmitted to I-CSCF or S-CSCF.I-CSCF considers the network security aspect, finishes network concealed function, and I-CSCF inquired about and determines to HSS and then initial user registration request is transmitted to S-CSCF by the S-CSCF that the user serves when the user registered.S-CSCF is the most crucial operation controlling entity of IMS, preserves user signing contract information, and the recording user call state is finished CCF.Different S-CSCF can connect different application server (AS), finish the different business function.Home subscriber server (HSS) is comprehensive concentrated customer data base, preserve user signing contract information and user state information, be used to support of the processing of each network entity, specifically comprise user ID (privately owned sign and public identify), user service information, user security relevant information, routing iinformation and positional information etc. calling and session.Between a plurality of entities interface is arranged in HSS and the network, be used for providing user profile and the user profile of preserving from other network entity to other network entity.IMS adopts Session Initiation Protocol as the mutual signaling of application layer, between terminal and the CSCF, between the CSCF, interface protocol is initial session protocol (SIP) between CSCF and the AS.
The tradition communication network is divided into circuit switching (CS) territory and packet switching (PS) territory, finishes circuit-switched service (comprising speech business, circuit type data service, fax etc.) and Packet data service respectively.The IMS business is made up of control section and media content portion, and control section is the IMS Signalling exchange between IMS terminal and the IMS territory entity, and the IMS business is controlled, and media content portion i.e. various content media streams such as image, voice, data, sound.IMS signaling and Media Stream are all by the Packet Based Network carrying, and Media Stream does not need the territory through IMS.Because CS is different for the processing of Internet resources with PS, CS is the exclusive resource type, PS then is the shared resource type, so for the demanding business of real-time, as speech business, realize and realize comparing with CS with IMS, its Quality of Service will descend to some extent, may not satisfy operator and user's business demand.For this reason, the 3GPP of International Standards Organization has proposed the notion of integrated service, multimedia service is undertaken by the mode that PS carrying and CS carrying combine, mainly with the demanding speech business of real-time, still by the CS carrying, the less demanding business of other real-time is as picture, messaging service etc., then by the PS carrying, IMS finishes control.Integrated service network block diagram as shown in Figure 1, the user is a basically identical to the multimedia service that the business experience and the IMS of integrated service provides.
The integrated service that IMS and CS carrying combine comprises two kinds of situations: increase the IMS session in existing CS calling, or set up CS and call out in existing IMS session.Both of these case all needs to consider capability negotiation, comprise terminal capability and network capabilities, terminal capability includes but not limited to video, Multimedia Message, recreation etc., and network capabilities includes but not limited to network type such as EDGE, GSM, GPRS, UMTS etc., and the professional ability that provides of network etc.
Set up CS when two terminals and called out, a certain side wishes and the other side sets up before the IMS session, needs to understand the common ability of both sides; Equally, when two terminals have been set up the IMS session, a certain side wishes and the other side sets up before the CS calling, also needs to understand the common ability of both sides.But at present the integrated service that combines for IMS and CS carrying is used, and belongs to the problem of studying, and wherein capability negotiation mechanism is not had feasible scheme as yet.
Summary of the invention
The invention provides a kind of in integrated service the fulfillment capability negotiation method so that in the integrated service that IMS and CS carrying combines is used, make terminal before carrying out integrated service, can obtain the common ability that communication two party is supported.
The invention provides following technical scheme:
A kind of in integrated service the fulfillment capability negotiation method, this method comprises the steps:

Embodiment
The present invention is carried providing capability negotiation mechanism in the integrated service that combines at IP Multimedia System (IMS) and circuit switching (CS), make terminal in existing CS calling, increase the IMS session service, or on existing IMS session service, set up and to obtain the common ability that both sides support before CS calls out.Described ability comprises the ability of terminal capability and terminal place network.
Initiate integrated service for the convenience of the user, terminal by the integrated service of supporting IMS and CS carrying combination provides corresponding user interface, make the user can pass through menu option or button operation, in existing CS calling, increase the IMS session service, or on existing IMS session service, set up CS and call out.
After communication two party has been set up first kind of service bearer (CS voice bearer or IMS sessions carry), the employed terminal of user no longer changes, therefore terminal capability is definite, and the ability of terminal place network then may change with customer location variation and network signal variation.So, the capability negotiation process is carried out when the user wishes to initiate integrated service, promptly before first kind that has set up the another kind of carrying of professional increase, carry out, rather than when setting up first kind of service bearer, the user carries out capability negotiation, this not only helps reducing unnecessary signaling, and terminal obtains is to initiate integrated service network capabilities constantly.
For example: user A and user B at first set up CS and call out, and whether uncertain this business of both sides will be an integrated service (increasing the IMS session in the CS calling procedure) or just once simple speech business (not increasing the IMS session before the CS end of calling) when setting up the CS calling; User A wishes to send picture to user B after supposing to converse 5 minutes, and then user A enters the integrated service menu by terminal interface, promptly triggers integrated service, that is to say that this business is integrated service.To have many business options in the integrated service menu, after entering the integrated service menu, user A (selects before any integrated service option), need carry out the capability negotiation process, be that the ability negotiations process is to carry out before the user initiates the integrated service request, rather than when the CS call setup, carry out; Its reason is when the user sets up first kind of service bearer, can not determine follow-uply whether can initiate integrated service; The interim of service bearer in initiating first kind of service bearer and second, because of the variation of customer location and network signal, user place network may change, and its network capabilities also changes.
The terminal A that the capability negotiation process is initiated integrated service by needs initiates, its process as shown in Figure 2, concrete steps are as follows:
(1) terminal A consults request to the application server transmitting capacity.Carried terminal A sign and terminal A place network identity in request message, terminal iidentification can be the URL address of IMEISV or the entity of depositing terminal ability information, perhaps direct carried terminal A ability and terminal A place network capabilities in the message; The sign that also will carry distant terminal B in the while message.
If carried terminal sign and network identity in the request message, then application server obtains the ability of terminal A ability and terminal A place network from corresponding network entity (as database).
(2) application server is to terminal B requesting terminal B and terminal B place network capabilities.
(3) terminal B responds to the request of application server resettability.Carried terminal B sign and terminal B place network identity in response message, terminal iidentification can be the URL address of IMEISV or the entity of depositing terminal ability information, perhaps the ability of direct carried terminal B ability and terminal B place network in the message.
If carried terminal sign and network identity in the response message, then application server obtains the ability of terminal B ability and terminal B place network from corresponding network entity (as database).
(4) application server obtains the ability of terminal A, B ability and terminal A, B place network, draws the common ability that both sides support, and sends to terminal A and terminal B respectively.Because be that terminal A initiates integrated service, therefore, application server also can only send to terminal A with common ability.
At in existing CS calling, increasing the IMS session service, or on existing IMS session service, set up CS and call out two kinds of situations, the aforementioned capabilities negotiations process can be undertaken by different signalings and bearing mode, for saving Internet resources, carries out capability negotiation by setting up professional territory as far as possible.Two kinds of situations are as follows:
A, when existing IMS session service, terminal can be consulted by IMS territory initiating capacity, the mutual signaling utilization of capability negotiation between terminal and the application server can realize the expansion of existing SIP signaling, finish the capability negotiation of communication two party by SIP OPTION interacting message, and expand the description content of Session Description Protocol (SDP) wherein.
B, when existing CS calls out, terminal can be consulted by CS territory initiating capacity, adopts proprietary capability negotiation interaction message between terminal and the application server, the capability negotiation signaling is carried by non-structure supplementary service data (USSD) or short message (SMS); Its advantage be to the CS network without any need for enhancing, and do not need to set up simultaneously being connected of two territories of CS and PS (IMS control signaling is carried by the PS territory), because the part terminal does not support to have simultaneously CS to be connected with PS with network.
Route among Fig. 2 between terminal and the application server if this negotiations process is undertaken by the IMS territory, then adopts IMS territory routing mode according to existing normal network routing mode, if this negotiations process is undertaken by the CS territory, then adopts CS territory routing mode.Described application server can be a physical entity independently in the network, also can be and is arranged on functional entity on other network equipments.
With other another kind of capability negotiation process of said process phase region, be between two terminals, directly to carry out, do not need the participation of application server, as shown in Figure 3:
The terminal A that initiates integrated service by needs is to the request of terminal B initiating capacity, and in request carried terminal A ability and terminal A place network of network ability; Terminal B after the capability requests that receives terminal A to terminal A resettability request response, and in response message ability and the terminal B place network of network ability of carried terminal B.Because be that terminal A initiates integrated service, therefore, terminal A also can not carry the ability of local terminal in capability requests, and only by the ability of terminal B carried terminal B ability and place network thereof in response.
Terminal capability negotiation in the existing SIP signaling is this mechanism, the end-to-end capability negotiation of initiating in the CS territory, then can adopt this proprietary end to end capability negotiation signaling of short message (SMS) or User-to-User Signaling (UUS) carrying, both of these case all requires the direct carried terminal ability of terminal and terminal place network of network type and/or network capabilities.
The purpose that aforementioned capabilities is consulted is to make terminal can only initiate integrated service within the common limit of power of both sides, therefore, in realizing the integrated service process, can adopt one of aforementioned two kinds of methods to finish capability negotiation.As shown in Figure 4, set up CS between terminal A and the terminal B and called out, used capability negotiation shown in Figure 2 and realize that the process of increase IMS session service is as follows:
1, carries out the CS call business between terminal A and the terminal B.
2, user A wishes to increase the IMS session service to user B transmission picture, and the integrated service menu that the user enters terminal A triggers integrated service.
3, terminal A consults request to the application server transmitting capacity, and in request message ability, the ability of terminal A place network and the sign of terminal B of carried terminal A.
4, application server is to terminal B requesting terminal B and terminal B place network capabilities.
5, terminal B is to application server resettability request response, and in response message the ability of terminal B and the ability of terminal B place network.
6, application server obtains the ability of terminal A, B ability and terminal A, B place network, draws the common ability that both sides support, and sends to terminal A and terminal B respectively.
7, terminal A judges whether integrated service belongs to the business that the common ability of terminal and network is supported, and on menu, each integrated service option of common ability support is become available options, as, will send the picture option and become available (supposing that common ability support sends picture); Unsupported each integrated service of common ability is become unavailable option.
For example: the integrated service option that terminal provides at most comprises: initiate audio call, transmission picture, transmission video, recreation, transmission Multimedia Message, transmission text, transmission of audio etc., but judging a common ability support voice after handling capacity is consulted calls out, sends picture, sends Multimedia Message and transmission text, other business option is not supported, therefore, audio call, transmission picture, transmission Multimedia Message and these service selection of transmission text as available options, are normally shown on user interface; Transmit video, recreation and transmission of audio then as unavailable selection, its option color becomes " grey " or does not show that the user just can only select the service selection that common ability is supported like this, initiates corresponding integrated service on the user interface.
8, the user clicks the business option that sends picture in the menu and sends picture (supposing that common ability support sends picture).
In said process, if terminal can not change the user interface of its integrated service option, then can be according to common ability, when the user initiates integrated service, terminal is accepted and is normally initiated the integrated service that common ability is done support, directly refuses the unsupported integrated service of common ability.
Below only the present invention will be described with preferred embodiment, and those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
