Description
Technical field
The present invention relates to the network communications technology, particularly a kind of method of realizing interface resource, system and equipment.
Background technology
In System Architecture Evolution/Long Term Evolution of future generation (System Architecture Evolution:SAE/Long Term Evolution:LTE) network, in order to finish the routing addressing function better, and minimizing message time delay, network layer in the conventional telecommunications net is abandoned, application layer is directly placed on the transport layer SCTP (Stream Control Transmission Protocol:SCTP), utilize internet protocol (IP) layer to finish routing addressing function in transmission control protocol/internet protocol (TCP/IP) network.
The S1 interface is the interface between evolution wireless access network in the SAE/LTE network architecture (Evolved Radio AccessNetwork:Evolved RAN) and the mobile management entity (Mobility Management Entity:MME).
In the present SAE/LTE network,, then can finish indirect control and supervision by this state of user to S1 interface connection status if the S1 interface connects a user.After the user was registered to core net, MME can keep this user's contextual information, and this contextual information can be in active state.After the S1 interface connection of Evolved RAN side is broken down, if core net need send signaling to terminal, then this signaling is dropped at Evolved RAN, and Evolved RAN returns wrong indication to MME, and MME receives the resource that can discharge this S1 interface after mistake is indicated; If Evolved RAN does not return wrong indication, after MME side signaling is overtime, also can discharge the resource of this S1 interface;
Accordingly, break down if the S1 interface of MME side connects, if terminal need send signaling to core net, then this signaling is dropped at MME, and MME returns wrong indication to Evolved RAN, and EvolvedRAN can discharge the resource of this S1 interface; If MME does not return wrong indication, after Evolved RAN side signaling is overtime, also can discharge the resource of this S1 interface.
Do not having between core net and the terminal under the situation of interacting message, breaking down,, when state of user is non-activity attitude, can discharge the connection of self S1 interface because MME can monitor state of user when the S1 interface of Evolved RAN side connects; If but the S1 interface of MME side connects and to break down, then the S1 interface resource of Evolved RAN side can not discharge.
When if the S1 interface connects the carrying that corresponds to a multicast (Multimedia Broadcast and MulticastService:MBMS) business, can finish indirect control and supervision to S1 interface connection status by the state of MBMS carrying, monitor procedure is identical with the situation that the connection of S1 interface corresponds to a user.
In sum, at present on the SCTP of SAE/LTE network layer, the state that connects for the S1 interface relies on User Status or MBMS service bearer state to carry out indirect monitoring fully, thereby cause when the connection of the S1 of MME side interface is broken down, Evolved RAN can't discharge the resource problem of corresponding S1 interface, and monitoring efficiency is low, speed is slow.
