Method and device for transmitting data spanning different protocols based network field

Abstract

The invention discloses a method and an apparatus of data transfer across network domains based on different protocols, wherein, the method is applied in data transfer between signaling network 7 and signaling network controlling the message adaptation layer of part of the users based on the signaling connection of internet protocol (IP) domain, which comprises the following steps: a signaling gateway (SG) receives connection-oriented data message from feed-forward connection section established between the signaling network 7 or the SUA signaling networks based on IP domain, the message is ensured to be transmitted by crossing the signaling network 7 or the SUA signaling network based on IP domain according to the object user address carried by the message, the message is realized the SUA protocol conversion or the SCCP protocol conversion; the feed-back connection section corresponding to the feed-forward connection section is confirmed by the SG according to the saved information of the connection section, then the protocol converted message is transferred through the feed-forward connection section. The method and the apparatus provided by the invention realize the data transfer across network domains based on different protocols.

Description

technical field [0001] The invention relates to a method for transmitting data in a communication system, in particular to a method and device for transmitting data across network domains based on different protocols. Background technique [0002] In the communication system, there are two ways to transmit data, one is to establish a connection channel, and the data is carried in a connection-oriented data message through the establishment of a connection channel; the other is not to establish a connection channel, and the data is carried in a connectionless data message in transmission. [0003] A signaling node using the SCCP (Signalling Connection Control Part) protocol can transmit data in the above two ways. In this signaling node, the SCCP protocol can provide a connection-oriented and connectionless terminal for the upper layer protocol. end-to-end data transmission. Fig. 1 is the schematic diagram of the protocol stack in the signaling node using the SCCP protocol ...

Problems solved by technology

That is to say, if the SG has a certain memory capacity, it cannot forward more connection-oriented data messages with different connection channels than the memory capacity limit at the same time, so that the efficiency of SG in processing connection-oriented data messages will be reduced.

[0012] After the SG establishes the connection channel, how to forward the connection-oriented data message carrying data through the connection channel, and how to directly forward the data in the connectionless data message without establishing the connection channel, there is no relevant information at present. technical description
