Description
Technical field
The present invention relates to network communications technology field, be meant a kind of method that detects the user's communication aborted especially.
Background technology
Along with the continuous expansion of internet scale, various network services are fallen over each other to emerge in large numbers, and advanced multimedia system also emerges in an endless stream.Because real time business is comparatively responsive to characteristics such as network transfer delay, delay jitters, when sudden high file transfer (FTP) being arranged on the network or contain the business such as hypertext transmission (HTTP) of image file, real time business will be subjected to very big influence; In addition, because multimedia service will take a large amount of bandwidth, so also will make and need guaranteed key business to be difficult to be transmitted reliably in the existing network.So, to be transmitted reliably for guaranteeing key business, various service quality (QoS, Quality of Service) technology is just arisen at the historic moment.The Internet engineering duty group (IETF, Internet Engineering Task Force) has proposed a lot of service models and mechanism, to satisfy the demand of QoS.What industry was relatively approved at present is to use integrated service (Int-Serv, Integrated Service) model at the access or the edge of network, and uses differentiated service (Diff-serv, Differentiated Service) model at server.
The Diff-serv model only ensures QoS by the measure of setting priority level, though this model has the high characteristics of line efficiency, concrete effect is difficult to prediction.Therefore, industry is that the Diff-Serv model of backbone network has been introduced an independently bearer control layer, set up the special Diff-Serv qos signaling mechanism of a cover, and set up a resource management layer specially for the Diff-Serv network, the topological resource of supervising the network, this resource management Diff-Serv mode is called as the Diff-Serv of independent bearing control layer model.Fig. 1 is the schematic diagram of this model, and wherein, 101 is service server, belongs to service control layer, can realize functions such as soft switch, as Call Agent (CA); 102 is load network resource manager, belongs to bearer control layer; 103 is edge router (ER, Edge Router), and 104 is core router, and 103 and 104 all belong to bearer network.In this model, load network resource manager is responsible for configuration management rule and network topology, is client's service bandwidth application Resources allocation.Transmit client's service bandwidth application request and result between the load network resource manager of each management domain by signaling, and each load network resource manager is the routing information of professional application distribution etc.When the service bandwidth application of bearer control layer process user, will determine the path of customer service, load network resource manager can notify ER to transmit Business Stream according to the path of appointment.
In the prior art,, will discharge the shared resource of this session by load network resource manager initiatively to load network resource manager down distributing resource release message usually when CA detects user's on-hook.But, when aborted appears in conversation, it is user's on-hook, but because unforeseen abnormal conditions, CA may not detect conversation and occur interrupting, and session this moment continues to keep, in this case, load network resource manager will continue all to safeguard relevant data content that resource is occupied always but can't be used, thereby causes the deadlock of resource with router.
