Abstract
The invention discloses a method and a device for realizing subscriber state synchronization in an IP multimedia subsystem (IMS) domain. The method comprises the following steps that: when a subscriber does not hook on, a media gateway controller transmits an unconditional report detection on-hook event signalling to a media gateway timingly; after receiving the unconditional report detection on-hook event signalling and detecting that the subscriber is in an on-hook state, the media gateway reports an on-hook event informing signalling to the media gateway controller; and after receiving the on-hook event informing signalling, the media gateway controller judges whether to release the relevant control resources of the subscriber or not. Due to the adoption of the technical scheme, even if the on-hook informing event reported by the media gateway is lost, one side of the media gateway controller can release the relevant control resources of the subscriber in time, and the condition that the subscriber state mastered by one side of the media gateway controller is not consistent with the actual subscriber state, which is caused by the unusual condition that on-hook informing event reported by the media gateway is lost, can be avoided.
Description
Technical field
The present invention relates to next generation network IMS (IP Multimedia Subsystem, IP Multimedia System) technical field, relate in particular to the synchronous method and apparatus of a kind of IMS of realization territory User Status.
Background technology
IMS is 3GPP (3rd Generation Partnership Project, third generation partner program) proposes at the Release5 version, its core characteristics are to adopt SIP (Session Initiation Protocol, session initiation protocol) and with the independence that inserts, under the development trend of the network integration, 3GPP, ETSI (European Telecommunications Standards Institute, ETSI) and ITU-T (International Telecommunication Union-Telecommunication Standardization, ITU Telecommunication Standardization Sector) all in the network integration scheme of research based on IMS, realize the fusion of fixed network and mobile network, so IMS is considered to the dreamboat framework that will be next generation network.
Soft switch (Soft Switch) notion is progressively to grow up on the basis of IP phone in the later stage nineties 20th century, be in communication network by the arrowband to the broadband transition, progressively perfect in the process of packet switching evolution by circuit switching.Soft switch has had large-scale application at existing network, and IMS has not in the industry cycle obtained clearly as the full-service objective network that fixes and move fusion yet, and soft switch is to the IMS evolution trend that is inevitable.And after the legacy user is linked in the IMS territory by the fixed network access device, have a lot of situations and need compatible consideration, as: the user is in the normal talking state, perhaps No dialing in long time causes entering lock-out state behind user's off-hook, and the opposing party is for a long time permanent again or after side's on-hook causes a side of not on-hook to enter lock-out state.When the user who is in the normal talking state or user's on-hook of being in the lock state, should be with user's virtual condition in time synchronously to control appliance.
When the user enters lock-out state or normal talking state, virtual condition for real-time supervisory user, first kind of traditional way is: as shown in Figure 1, by MGC (Media Gateway Control, Media Gateway Controller) timer is set, issue respective user AuditValue audit signaling regularly for MG (Media Gateway, media gateway).And MG returns the current state that is detecting of user in AuditValue audit response signaling, comprise: MG is detecting the user, and on-hook and MG are detecting whether off-hook of user, judge the relevant control resource of proceeding to examine or discharge the user by MGC according to the current state that is detecting of user again: as the data field, User Status etc., concrete principle is: if the current detection hook state that is in, the relevant control resource that the user then is described is also in taking, continue to be provided with timer, issue AuditValue audit signaling behind the timer expiry; If the current detection off hook state that is in, it is free state that the relevant control resource that the user then is described is in initial condition, and then MGC returns to initial condition with User Status, and discharges the relevant control resource of MGC to this user.
Also having a kind of traditional method is initiatively uploaded state of passive wait user, if that is: on-hook takes place the user, can report onhook event, and MGC discharges user's relevant control resource according to onhook event.
But above-mentioned two kinds of traditional approachs all exist obvious defects, and are specific as follows:
1) first kind of conventional method can not the very first time becomes initial condition in the MGC side with user's relevant control resource recovery, so can not will issue very of short duration that the timer duration of AuditValue audit signaling is provided with because consider performance, generally be set at a few minutes, must wait until the actual change situation that can detect User Status behind the timer expiry, the communication network for high request is unacceptable like this.
2) the current status signaling that is detecting of MG active report of user can not abandon.In general, during user's on-hook, the MG very first time is to the success of MGC report of user onhook event, MGC issues the detection off-hook event to MG, discharge the relevant control resource of MGC, can't cause MG and MGC both sides User Status inconsistent this user, but in IP network, particularly network layer is unsettled UDP transmission, and the packet loss phenomenon probably takes place.And in a single day packet loss takes place, and MG is to the failure of MGC report of user onhook event, and the detection off-hook event of MGC also can't be assigned simultaneously, and this moment, MGC adopted traditional approach, and continuation sends AuditValue audit signaling, can not address this problem.Because MG is controlled by MGC fully, the state of its inspection still detects whether on-hook of user, will cause a fast knot like this, that is: MG thinks that hook state reports, and the state that MGC examines still detects in the on-hook, so User Status is will a direct screening dead, MGC can not get discharging to this user's relevant control resource.
Summary of the invention
