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); Be load network resource manager, belong 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.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of method that detects the user's communication aborted, load network resource manager is in time understood called out to connect the aborted that occurs, and discharge the shared resource of this calling.

C. after described Service Manager is received this stream ageing report, judge whether the pairing user of this session is online, if do not have online, confirm to occur aborted, notify this session of load network resource manager of described source aborted to occur, execution in step D then, otherwise, confirm aborted not occur, jump out this flow process;
D. pairing load network resource manager of this session and ingress router discharge the pairing resource of this session respectively.
Step B can comprise:
Described resources manager in attribution load-carrying net along this Session Resources requesting party to the upstream load network resource manager transmit this stream ageing report one by one, up to the source of this session load network resource manager, described source load network resource manager reports the stream ageing report to the pairing Service Manager of this session.
And the load network resource manager of source described in the step B can be passed through the RPT message among the COPS+, or the customization type in the TRAP message among the SNMP, or self-defining in advance message, reports the stream ageing report to the pairing Service Manager of this session.
In step C, notify after aborted appears in this session of load network resource manager of described source, and before execution in step D, this method may further include:
D1, described source explorer send stream mapping delete command to the pairing ingress router of this session, and transmit resource release request one by one to the load network resource manager in its downstream, until the purpose load network resource manager, and execution in step D then.
