Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of Agent Status detection method, device and system.
Background technology
SIP (Session Initiation Protocol, session initiation protocol) be a kind of application layer protocol of setting up in IP (Internet Protocol) network, revising and end Multimedia session, its application comprises voice, video, game, message, calling control etc.
SIP is due to its simplicity and extensibility, be adopted as afterwards VoIP (Voice over IP, IP phone) signaling protocol, and finally became the standard of IETF (Internet Engineering Task Force, Internet engineering duty group) in 1999.SIP has obtained further enhancing at aspects such as the optimization of interoperability, design and new features afterwards, and has formed new standard rfc3261.
IMS (IP Multimedia Subsystem, IP Multimedia System) is the subsystem that 3GPP is organized in the support IP multimedia service that proposes in the Release5 release criteria.IMS calls out controlling mechanism various types of multimedia services that create, manage and terminate with SIP.Various types of clients can be set up IP communication end to end by IMS, and can obtain needed service quality, can say that IMS provides the basis of integrated services, based on the IP technology, it is support voice, data and multimedia service and new application simultaneously.
Just because of above-mentioned advantage, IMS is just adopted by increasing operator, as UNE form of future generation.
In the IMS network, UE (User Equipment, subscriber equipment) realizes miscellaneous service by the agent equipment Access Core Network.Agent equipment may be SBC (Session Borden Controller, Session Border Controller), may be also P-CSCF (Proxy-Call Session Control Function, 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 a plurality of simultaneously, this situation is called many ownership, dual-homedly just refers to have simultaneously two agencies, and he is a kind of particular forms of many ownership, be also that present usage comparison is a kind of widely, it is mainly for following purpose that many ownership exist:
(1) load sharing: this form is because agency's traffic handing capacity is limited, all customer services that agency can't process to have under its command and a kind of form of adopting.Under this mode some users up by which agency be according to each agency's loading condition Random assignment.
(2) redundancy backup: this form is the requirement that is in the reliability disaster tolerance.Generally formed by 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 to process, thereby improves the reliability of business.
Under dual-homed networking, UE needs the up agency's of perception state so that switch between the agency, and this just need to detect agency's state.
Existing a kind of scheme is to adopt UE to act on behalf of the transmission of property independent periods based on the OPTIONS request of SIP to each, judge agency's availability according to the response of OPTIONS request, because the OPTIONS request all has nothing to do with user's registration and calling, therefore can not have influence on user's normal registration and calling.
To also have a kind of scheme be multiplexing UE registration flush mechanism, this mode refresh the state of judging the agency with other the response of message related to calls (for example initial INVITE request) by the registration in the cycle.
Yet, in cluster user equipment (number of users by hundreds of does not wait to several thousand), because user's agency is identical, therefore can detect by one and several users agency's state, all devices is switched and determined with the result according to detection per family.But the small dimension equipment that distributes for magnanimity (usually only have several by user's number, ONT (Optical Network Terminal for example, Optical Network Terminal)), each equipment independently testing mechanism still can cause a large amount of non-service messages to impact acting server, affects the performance of Business Processing.
