Problems solved by technology

For example, when the existing network is reconstructed, the links of the original network use Service Specific Convergence Sublayer (SSCS) links, and the protocol stack is as follows: image 3 Shown or MTP2 Peer to Peer Adaptation Layer Protocol (MTP2Peer to Peer Adaption Layer, referred to as M2PA) link, the protocol stack is as follows Figure 4 As shown, according to the agreement, it is not easy to expand
And the association used on the IP side (Association, the association is SCTP coupling, which provides the transmission of Protocol Data Unit (PDU) for one or more interfaces), if the narrowband link of MTP2 is used, for the IP side Bandwidth utilization is relatively low

Embodiment Construction

[0024] From the perspective of the protocol stack, the three protocols MTP2, SSCS, and M2PA have very important things in common:

[0025] a) The upper-layer users of MTP2, SSCS, and M2PA are all MTP3, and the positions of the three in their respective protocol stacks also belong to layer 2. Its function is to provide a reliable link guarantee for signaling transmission, and to notify the upper layer when the link is unavailable or the quality cannot meet the requirements. From this point of view, the three protocols that are also the underlying links have commonality.

[0026] b) MTP2, SSCS, and M2PA are exactly the same as the L3 interface primitives. This ensures that MTP3 does not need to care about the specific actual type of the underlying link during link maintenance, which is also an important guarantee for M2UA to expand its adaptation function.

[0027] The above-mentioned two main and key points in common make a general protocol stack (such as Figure 5 shown), a...

Abstract

The invention discloses a signaling gateway, a link circuit establishing method, a data transmission method, and a broken link processing method, wherein, the signaling gateway adopting an M2UA protocol comprises: a configuration module used for taking IID parameters of an physical interface of the signaling gateway as link identifications which is one-to-one corresponding to link numbers and configuring a protocol type of each link circuit; an analysis module used for analyzing the received IID parameters so as to obtain the link numbers and obtaining corresponding link types according to the link numbers; and a processing module used for processing treatments according to the link numbers and the protocol types of the link circuits. Wherein, the M2UA protocol can be adaptive to MTP2, SSCS, and / or M2PA. The treatments processed by the processing module comprise at least one of following: establishing link processing, data transmission, and a broken link processing.

Description

technical field [0001] The present invention relates to the communication field, and more specifically relates to a signaling gateway, a link establishment method, a data transmission method, and a link disconnection processing method. Background technique [0002] With the gradual maturity of IP network technology, IP network can be used to carry services such as voice, data, and multimedia. Traditional circuit-switched networks and IP networks are in the stage of integration. In order to realize the interconnection between traditional circuit-switched networks and IP networks, emerging The requirements for transmission of SS7 and other circuit-switching signaling protocols on IP networks. In order to meet the needs of transmitting signaling protocols on the IP network, the IETF network working group set up a special signaling transmission group. The IP network signaling transmission protocol (SIGTRAN protocol) they formulated supports the transmission of traditional circui...
