IMS user stage controlling method and system based on signature data

Abstract

An embodiment of the invention discloses an IMS user grade control method based on signed data and a system thereof, wherein the method comprises the following steps: when login request or conversation request of user is received, the user stage service control device obtains the user information corresponding with the user identification, respectively executing the QoS control of user grade, or registered user number control, or concurrent session control according to the obtained user information, wherein the user information is stored in the user database UDB. The embodiment of the invention can control the registered user number or concurrent session number. Furthermore when the IMS network is not deposited with NASS system, the service control accurate to user is executed according to the accountant opening signing data information of user.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an IMS user-level control method and system based on subscription data. Background technique [0002] At present, the IMS (IP Multimedia Subsystem) network mainly provides users with reliable QoS quality services through the proxy call session control function server P-CSCF, including bandwidth / throughput, delay, jitter, packet loss rate, availability, etc. In the IMS network, the QoS signaling control and resource allocation mechanism are independent of the session control protocol. It mainly completes functions such as authorization / update / revocation of media resources, confirmation of bearer reservation, gate control opening / closing, indication of bearer release / failure, etc. [0003] When accessing the fixed network, the application layer AF, which includes the proxy call session control function server P-CSCF (Proxy-CSCF) or the access network resource admissi...

Problems solved by technology

As a result, the QoS resources that can be used by ordinary users accessing the same BGF as home users or enterprise network users may be preempted by home users or enterprise network users, and their normal calls or other services are seriously affected.

[0009] In addition, when the NASS system is not deployed in the IMS network, the AF cannot obtain the maximum number of contact addresses and the maximum number of concurrent sessions of the user, and the control of the number of registered users and the number of concurrent sessions in the network can only be accurate to the granularity of the network element. At the same time, enterprise network users or home users registered in this network element cannot control the number of registered contact addresses and concurrent sessions

If the number of contact addresses and concurrent sessions registered by enterprise network users or home users is very large, since the registration and session behavior of home users cannot be controlled, the normal registration and sessions of ordinary users will be affected
