Transmission method of GT addressing based SUA message and device thereof

Abstract

The embodiment of the invention discloses a transmission method of a GT addressing based SUA message and a device thereof; the method comprises the following steps: a GT addressing based SUA signaling service message is received; GT code categorical attribute of the SUA signaling service message is determined; the corresponding translation and conversion are carried out to finish protocol handling according to GT address parameters related to the determined GT categorical attribute in the SUA signaling service message; wherein the GT code categorical attribute is used for expressing that the GT code data structure of the SUA signaling service message is defined by an ITU-T standard structure or an ANSI standard structure; in the technical proposal provided by the embodiment of the invention, the GT code format in an SUA protocol message can be distinguished, so as to enhance the communication of different protocols with different formats.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for transmitting SUA (Signaling Connection Control Part User Adaptation Layer) protocol messages based on GT (Global Title global code) addressing and the SUA protocol functional entities. Background technique [0002] See figure 1 It is a schematic diagram of the structure of the network protocol layer, such as figure 1 As shown, in the network hierarchical structure, the SCCP (Signalling Connection Control Part) protocol belongs to the functional layer of the network and transport layer. The SCCP protocol can cooperate with No.7 signaling according to the calling and called addresses provided by the user. Network MTP (Message Transfer Part, message transfer part) function, complete the SCCP network routing addressing function between signaling nodes. The SCCP protocol can analyze and find the next-hop destination address according to the calling and c...

Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that in the prior art: the SUA protocol can be used to transmit the SCCP protocol content of the ITU-T GT and the SCCP protocol content of the ANSI GT at the same time. When the two types of GT involve SUA interworking, For example: for the signaling gateway SG used to realize the intercommunication between the narrowband-based SCCP and the broadband IP-based SUA protocol, when the SG receives the SUA protocol message, it cannot correctly identify the GT in the received SUA protocol message The type of the code, so that the subsequent protocol processing cannot be performed correctly; or, when the SUA entity in the broadband IP-based SUA protocol network receives the SUA protocol message, it always thinks it is a GT code of the ITU-T type, so it cannot correctly process the SUA protocol message. Identify the type of GT code in the received SUA protocol message, so that subsequent protocol processing cannot be performed correctly
