Method and apparatus for customizing communication protocol, method and apparatus for converting communication protocol description

Abstract

The invention discloses a method for customizing communication protocol which comprises: determining information element IE needed by customized communication protocol and all kinds of attributes of the IE, matching the IE and attribute of IE to two-dimension relation according to level of IE and dependence relation of IE, matching different attributes of same IE to same row of two-dimensional relation, matching same attribute of different IE to same list of two-dimension relation. The communication protocol needed to be customized can be intuitively and regularly represented through IE, IE level, dependence relation of IEs and other attribute of IE because the communication protocol is described by adopting two-dimension relation, further program code aiming at the communication protocolis developed more easily, automation of the communication protocol is easy. The invention also discloses a device for customizing communication protocol, method and device for converting communication protocol description.

Description

technical field [0001] The invention relates to the realization technology of the communication protocol, in particular to a method and device for customizing the communication protocol, and a method and device for converting the description of the communication protocol. Background technique [0002] In a communication system, communication between different entities must be carried out according to a certain communication protocol. The interaction of messages of different communication devices is also carried out in accordance with the message format stipulated in the protocol. The realization of the communication protocol is the key step of the communication system. Each interface in the communication system has a dedicated communication protocol, including its message encoding method. At the same time, considering the transmission efficiency and other issues, most interface messages define their own encoding method. The sender encodes the message into a code stream acc...

Problems solved by technology

[0004] In the development of communication systems, due to the need to develop protocol-specific program codes in the later stage, including codec codes, message construction and analysis functions, protocol message tree table code generation, etc., if these codes are developed manually, it will It takes a lot of manpower, and the later maintenance is also troublesome, and the protocol upgrade will bring changes in the program code

Therefore, it is necessary to adopt an automated way to realize these code developments. Although ASN.1 provides a representation method for describing the abstract grammar structure and content, it is not intuitive for the description of the hierarchical relationship of the message tree in the communication protocol, the expression of IE element dependencies, and the IE type. , IE range description can only be obtained through the keyword semantics in ASN.1, and to realize these code automation methods need to provide a protocol description expression that is more intuitive, regular, and easy to automate
