Problems solved by technology

[0009] At present, the method of running DPNSS 1 and DASS 2 protocols on the same set of equipment at the same time is: run DPNSS 1 and DASS 2 respectively through different E1/T1 interfaces, that is, one E1/T1 interface can only transmit messages

Example Embodiment

[0041] In actual networking applications, the same set of equipment will run DPNSS 1 and DASS 2 protocols at the same time, and they need to be carried by the same DUA protocol. For example, the DPNSS 1 and DASS 2 protocols carry the same DUA between the SG equipment and the MGC equipment at the same time. The agreement is first class. If the same DUA protocol and the same E1 or T1 line can carry both the DPNSS 1 protocol and the DASS 2 protocol, and the receiving end can accurately distinguish whether the message it receives is a message of the DPNSS 1 protocol or a message of the DASS 2 protocol , The receiving end can process the messages of different signaling protocols received from the same interface by the corresponding protocol, which can effectively save the interface resources of the network equipment and reduce the cost of system networking.

[0042] Therefore, the core of the present invention is to set protocol identification information corresponding to different sig...

Abstract

The key ideal of the invention comprises: setting different protocol identifiers for different signaling systems; the sending end sends a message and the protocol identifier corresponding to said message to the receiving end; according to the received identifier the receiving end determines a signaling system protocol corresponding to said protocol identifier. By the invention, the messages using different signaling protocols can be transported through one transmission port so as to avoid using different ports to transport different protocol messages.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a message transmission method and device 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. SIGTRAN ...
