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 of one protocol, so , if the DPNSS 1 and DASS 2 protocols need to be run simultaneously on the same set of equipment, two E1 / T1 interfaces need to be occupied, which wastes precious E1 / T1 resources and increases the networking cost of the system

Embodiment Construction

[0041] In actual networking applications, DPNSS 1 and DASS 2 protocols will run simultaneously on the same set of equipment, and they need to be carried by the same DUA protocol. For example, DPNSS 1 and DASS 2 protocols simultaneously carry the same DUA between the SG device and the MGC device Protocol first class. If the same set of DUA protocols and the same E1 or T1 line can simultaneously carry 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 according to the corresponding protocol, so as to effectively save the interface resources of the network device and reduce the system networking cost.

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

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 ...
