Problems solved by technology

[0016] In practical application, the above-mentioned solution has the following problems: the protocol implementation of the existing technical solution is relatively complicated, the overhead is relatively large, and the system resources cannot bear it when the number of MGWs is large, and the existing technical solution does not support the use of the MGCP protocol as a link between the MGC and the MGW. control protocol
[0017] The main reason for this situation is that the implementation of the SCTP protocol used in the existing technical solutions is more complicated than that of the TCP and UDP protocols, and the protocol overhead is large
However, since the number of MGWs may be very large, even more than a million, it is difficult to meet the requirements for system resources at this time. In addition, because MGCP can also be used as the control protocol between the MGC and MGW, the MGCP protocol can only carry On the UDP protocol, existing technical solutions cannot be used in this scenario

Embodiment Construction

[0039] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] Compared with SCTP, the TCP and UDP protocols are more widely used, the protocol implementation is simpler, and the system resource consumption is less. The present invention carries the control protocol between MGC and MGW on TCP or UDP, in order to avoid TCP or UDP protocol transmission The delay is uncontrollable and the transmission is unreliable. The present invention also adds the function of multi-IP address communication on the MGC, and accordingly configures multiple IP addresses for one MGC at the MGW, and uses the function of multi-IP address communication to establish multiple TCP or The UDP transmission link guarantees the real-time performance and reliability of the control protocol between MGC and MGW.

[0041] The control protocol bearer syste...

Abstract

Being related to technique for carrying communication protocol, the invention discloses system and method for carrying media gateway control protocol in order to implement carrying control protocol between MGC and MGW more reliably. Through increasing communication function of multiple IP addresses, the invention can establish multiple UDP or TCP transmission links between MGC and MGW to carry media gateway control protocol. Thus, if message sent from one UDP or TCP transmission link does not obtain response in prearranged time length, then re-transmission can be carried out through another UDP or TCP transmission link. In addition, load can be partaken among transmission links in UDP or TCP.

Description

Technical field [0001] The present invention relates to the bearer technology of communication protocols, in particular to the bearer technology of communication protocols in a network where bearer and control are separated. Background technique [0002] With the development of communication technology, the communication network is also evolving rapidly to the Next Generation Network (NGN for short). Among them, the development trend of switching technology is to separate service control and bearer media. Through the separation of service control and bearer media, users can configure and define their own service characteristics without having to care about the network form of bearer services and terminal types, making the provision of services and applications more flexible, so as to meet the continuous development and update of users The business requirements of the network also make the network have scalability and the ability to quickly deploy new services, making network oper...
