Conversation management control method of IP bearing net

Abstract

The method comprises: the first bearer controller sends a detection message to the second bearer controller in order to detect the state of bearer network between two bearer controllers; the second bearer controller reports the received detection message to the service controller; according to the detection message, the service controller makes session control. By invention, the service controller can get the state of bearer network in each time interval, and according to the information about the state of bearer network, takes relevant operations.

Description

Technical field [0001] The present invention relates to the field of communication, and in particular to a session management control method of an IP bearer network. Background technique [0002] On IP-based bearer networks, session management control is a very important technology when carrying various services. When the bearer network is overloaded, the admission of new sessions must be restricted, otherwise the addition of new sessions will affect the communication quality of all sessions in all bearer networks. [0003] Currently, there are a variety of IP session management control technologies, and the more common ones mainly include Resource Reservation Protocol (RSVP) technology and softswitch technology. [0004] For RSVP technology, this technology is to make a resource reservation request on the routing device before a new session is established to reserve resources for the established session. If the resource reservation is successful, the session is agreed to be acce...

Problems solved by technology

[0008] However, when the current bearer network bandwidth is still sufficient, due to the existence of peaks in the bearer network, the transmission delay or jitter of service data packets increases in a short period of time, and the MGW may misjudge this situation as quality degradation, resulting in According to the wrong quality report, the MGC adopted wrong session management control policies such as rejecting new session access or tearing down some sessions; moreover, due to the inherent characteristics of the IP bearer network, as long as the service traffic does not exceed the designed traffic, it will not occur any loss of quality

Therefore, only when the service volume of the bearer network has exceeded the designed flow rate and the service quality of all established sessions has degraded, can the MGW detect the service quality degradation. Therefore, the MGC can only , to implement the corresponding session management control strategy, resulting in poor user experience for all users who have established sessions, and the effect of CAC is not very good
