Embodiment Construction

[0028] figure 1 , figure 2 It has been described in the background technology, so it will not be repeated here.

[0029] image 3 It is a structural diagram of the present invention, including three links: an external message sending / receiving message pre-decoding and distribution link, an H.248 centralized maintenance link, and an H.248 distributed processing link. The combination of these three links realizes high-capacity H.248 protocol processing and smooth capacity expansion.

[0030] Message sending / receiving The message pre-decoding and distribution link sends H.248 messages externally; receives external messages internally, and after pre-decoding, it is judged whether to send them to the distributed processing processor or the centralized maintenance processor. The pre-decoding link identifies each H.248 message entering the system. The processor of the .248 message is a key link in the present invention to realize distributed processing and distribution. The cent...

Abstract

The invention discloses a large-capacity H.248 protocol distributed processing system and method. The system includes: one or more H.248 interface boards, one or more H.248 distributed processors, H.248 centralized Maintenance processor; after the external H.248 message is pre-decoded, for ordinary H.248 messages, the message is forwarded to the H.248 distributed processor; for centralized maintenance messages, the message is forwarded to the H.248 centralized maintenance processor for distribution processing. Adopting the method of the invention can solve the problem that the H.248 protocol cannot smoothly expand the capacity, and can support a large increase in the H.248 call processing capacity, which is a key technical breakthrough for solving the large-capacity MGW and MGC in the NGN system.

Description

technical field [0001] The present invention relates to the field of communications, in particular, to the large-capacity MGC (media gateway controller) and MGW (media gateway) in the NGN (next generation network, such as WCDMA / CDMA2000 / TD-SCDMA / SOFTSWITCH) system in the field of communications Distributed processing system and method of H.248 protocol. Background technique [0002] The H.248 protocol is adopted by organizations such as 3GPP / 3GPP2 as a protocol standard for the separation of NGN network bearer and control, and is mainly used for gateway control between MGC and MGW and bearer establishment control. [0003] H.248 is used for communication between MGC and MGW, and messages can be coded in text mode or binary mode. H.248 message lengths are typically between 100 and 300 bytes. The unencoded message format is attached figure 1 As shown, H.248 messages are nested from outside to inside in order of transaction (Transaction) / action (Action) / command (Command): ...
