Background technology
SIP (SessionInitiationProtocol, session initiation protocol) be a kind of application layer protocol set up in IP (InternetProtocol) network, revise and stop Multimedia session, its application comprises voice, video, game, message, Call-Control1 etc.
SIP is due to its simplicity and extensibility, be adopted as VoIP (VoiceoverIP afterwards, IP phone) signaling protocol, and finally became the standard of IETF (InternetEngineeringTaskForce, Internet engineering duty group) in 1999.SIP obtains further enhancing in the optimization and new features etc. of interoperability, design afterwards, and defines new standard rfc3261.
IMS (IPMultimediaSubsystem, IP Multimedia System) is the subsystem that 3GPP is organized in the support IP multimedia service proposed in Release5 release criteria.IMS uses SIP Call-Control1 mechanism to create, manage and terminate various types of multimedia service.Various types of client can set up IP communication end to end by IMS, and required service quality can be obtained, can say that IMS provides the basis of integrated services, based on IP technology, it is support voice, data and multimedia service and new application simultaneously.
Just because of above-mentioned advantage, IMS just adopt by increasing operator, as UNE form of future generation.
In the ims network, UE (UserEquipment, subscriber equipment) realizes miscellaneous service by agent equipment Access Core Network.Agent equipment may be SBC (SessionBordenController, Session Border Controller), also may be P-CSCF (Proxy-CallSessionControlFunction, Proxy-Call Session Control Function).
An agency can serve many users simultaneously, and a user only uses an agency up in a certain moment.The agency that can serve same subscriber equipment may exist multiple simultaneously, this situation is called many ownership, and dual-homed just referring to has two agencies simultaneously, and he is a kind of particular form of many ownership, also be use one more widely at present, many ownership exist mainly for following object:
(1) load sharing: this form is because the traffic handing capacity of agency is limited, agency cannot process all customer services had under its command and a kind of form adopted.Under this mode, some users are up by which agency is according to the loading condition Random assignment of each agency.
(2) redundancy backup: this form is the requirement being in reliability disaster tolerance.Generally be made up of a primary agency and one or more backup agents, primary act on behalf of fault after, business can be transferred to backup agent and continue process, thus improves the reliability of business.
Under dual-homed networking, UE needs the state of the up agency of perception so that switch between agency, and this detects the state of agency with regard to needing.
Existing a kind of scheme adopts UE to ask the OPTIONS of each transmission acting on behalf of property independent periods based on SIP, the availability acted on behalf of is judged according to the response of OPTIONS request, because OPTIONS request is registered and call out all irrelevant with user, normal registration and the calling of user therefore can not be had influence on.
UE registers flush mechanism to also have a kind of scheme to be multiplexing, and this mode refreshes the state judging with the response of other message related to calls (such as initial INVITE request) to act on behalf of by the registration in the cycle.
But, in cluster user equipment (number of users is not by hundreds of to several thousand etc.), because the agency of user is identical, therefore can be detected the state of agency by one and several user, all devices is with being switched and determined according to the result detected per family.But the small dimension equipment distributed for magnanimity (usually only have several by user's number, such as ONT (OpticalNetworkTerminal, Optical Network Terminal)), each equipment independently testing mechanism still can cause a large amount of non-service messages to impact proxy server, affects the performance of Business Processing.
