Embodiment Construction

[0039] The core of the present invention is to extend the data link connection state message, and transmit the channel state information of each channel to the opposite end according to the extended data link connection state message.

[0040] The technical solution provided by the present invention will be further described below based on the core idea of ​​the present invention.

[0041] In the current DPNSS 1 protocol, a channel can contain up to 5 status values, namely: OUT OFSERVICE (exit service), IDLE (idle), RESET ATTEMPTED (reset attempt), RESET COMPLETE (reset completed), INFORMATION TRANSFER (information transmission), other channel status values ​​may also appear in the future. In order to realize the transmission of these channel status information, the present invention needs to expand the DLC Status Message. The method of message expansion in the present invention is very flexible. The following mainly introduces two kinds of message expansion Methods.

Abstract

A method for transmitting channel state information based on DUA protocol includes extending connection state message of data link then transmitting channel state information of each channel to opposite end according to extended connection state message of data link. The method can utilize multiple extension mode to carry out extension of data link connection state message in order to satisfy query requirement of channel state.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for transmitting channel state information based on the DUA protocol. Background technique [0002] NGN is the abbreviation of the next generation network system, and NGN is gradually replacing the current traditional PSTN (Public Switched Telephone Network). Compared with the traditional PSTN network, the biggest difference between NGN and traditional PSTN is the separation of control system / bearer network and IP-based voice. [0003] In the next generation network, the concepts of "media gateway controller" and "media gateway" are proposed. When the original PSTN signaling is moved to NGN, the interlayer protocol will be separated and run in different network components. To achieve this For this purpose, SIGTRAN (Signaling Transport) signaling was introduced. [0004] SIGTRAN signaling is formulated by a special SIGTRAN working group established by IETF...
