Background technology
IMS is that the framework of the standardized opening of 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) proposition is realized diversified multimedia application; The terminal equipment of IMS is realized by IMS entity user equipment (UE, User Equipment) conventionally, and terminal equipment has comprised the user side of supporting various multimedia application in IMS, is IMS business and direct experience and the interaction end that is applied in user's side; Access side user's telecommunication management is by the privately owned mark of the IMS (IMPI for its distribution, IMS Private Identity), IMS public identify (IMPI, IMS Public Identity) realize, IMPI and IMPU relevant information are kept in IMS service identification module (ISIM, IMS SubscriberIdentityModule).
IMS uses session initiation protocol (SIP, Session Initiation Protocol) to realize foundation and the control of the session of UE; SIP (Session Initiation Protocol, session initiation protocol) is the application layer control protocol that carries out multimedia communication in IP network that IETF proposed and presided over research; Session Initiation Protocol is generally used for Multimedia session control, can be used for setting up, revises and stop Multimedia session; Can invite participant to participate in the session having existed; Can be used for revising the media (as increased or a media links of deletion) that had session.User agent (UA, User Agent) is the logic entity of Session Initiation Protocol, and it comprises a User Agent Client (UAC), be used for produce request, meanwhile, it also comprises a User Agent Server (UAS), is used for response request.A common user side realizes a kind of business or services sets need to realize UA function logic.
The opening of business and flexibility are the important feature of IMS architectural framework, by realizing session control layer and being separated based on IP bearing bed, and further realize separating of operation layer and key-course, make the horizontal pattern that is developed to of business, no matter to the also develop and field of telecommunication service of the Internet, and fusion between business provides desirable platform.Along with the growth of user to multimedia service demands such as voice, image, word, videos, the related service of disposing in IMS also progressively presents diversified trend, and the carrier presenting in user's side as business---user side---is also tending towards variation.Because various multi-medium datas for user should merge, the fusion of this user side to different business in IMS brings new requirement.
A kind of thought that merges is to adopt unified integrated mode, the user side of all IMS business is integrated in an application, and then realize fusion by Floor layer Technology, because application can manage the user side of different business in Unified Set, can reach like this object of effective integration, similarly application can be with reference to RCS (Rich Communication Suite, Rich Media's communication suite).But the problem that this mode is brought is also apparent: while needing new user side when there being new business to dispose, just must revise original application, and wait for that original application extension just can be used after completing, the exploitation of different user end and integration easily cause exploitation bottleneck, can bring the scaling problem of application.
With respect to unified integrated mode, a kind of mode that can effectively solve exploitation bottleneck and scaling problem is exactly that the user side of different business on UE is by the application realization of separate separation, the UA representing as dotted line in Fig. 2 by signaling flow independently and exterior I MS network signal alternately as shown in, the user side of a business is regarded in each application as, this mode is also brought problems, mainly from the viewpoint of three:
The first, message storm problem, for different user end, due between can not mutually work in coordination with, there is oneself independently interacting message with IMS network, and the message with identical function can cause message redundancy, frequent during with IMS network interaction message when multiple application, bring message storm to IMS network, cause IMS offered load pressure; Be typically the registration message of user side, in the time that the different user end in same UE has all needed registration, message redundancy and the message storm bringing are obvious;
The second, contention for resources problem, for different user end, due between can not mutually work in coordination with, in the time all needing to use certain resource of UE, such as microphone, loud speaker etc., cannot unify contention for resources to coordinate and manage, can bring contention for resources problem, the confusion that causes resource to use;
The 3rd, applicating cooperation problem, in IMS architectural framework, IMPU is the mark that user side is realized service interaction, the IMPU quantity that is generally a UE distribution is limited, can cause in the time that user side increases, certain user on same UE holds and shares same IMPU, although Fork mechanism can be sent to request, but the professional ability of these client suppors is not unified management, on same UE, more can produce conflict, in the time of passive reception service request, can bring applicating cooperation problem---cannot determine by the service request of reception send to share one IMPU's and all meet the user side of this professional ability.While being typically an IMPU as the object URI of voice call request, what How to choose responded this request shares this IMPU support voice professional ability user sides all.
