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 invention relates to the communication field, in particular to a session management and control method of an IP bearer network. Background technique [0002] When carrying various services on an IP-based bearer network, session management and control is a very important technology. When the bearer network is overloaded, it is necessary to limit the acceptance of new sessions, otherwise, the addition of new sessions will affect the communication quality of all sessions in all bearer networks. [0003] Currently, there are various IP session management and control technologies, among which the more general ones mainly include Resource Reservation Protocol (Resource Reservation Protocol, RSVP for short) technology and softswitch technology. [0004] For RSVP technology, this technology is to make a resource reservation request to the routing device before the new session is established, and reserve resources for the established session. If the resour...

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
