Embodiment Construction

[0066] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0067] see figure 1 , which is a schematic structural diagram of the protocol message parsing system of the present invention. The protocol message parsing system includes a rule base unit 1 and a general interpreter 2 . in:

[0068] Rule base unit 1: it is composed of rule statements, and the rule statements are composed of rule symbols, wherein the rule symbols are used to describe the message structure and related logic control actions, and the actions refer to the Necessary judgments, jumps, connections, etc.; rule statements are used to describe specific actions of a certain parsing process; and the rule base unit describes the parsing process of the protocol.

[0069] The general interpreter 2 receives the bit stream of the protocol message that needs to be parsed, and matches the bit stream in the rule base unit 1, and extracts the message type and its cont...

Abstract

This invention provides a analysis method and system for protocol information composed of some IEs. Wherein, the method comprises following steps: 1) dividing and selecting a set rule signs for control action from all logic control actions used in protocol analysis process, the control action comprises: positioning IE position, connecting and uniting IE, calculating, deciding and outputting the IE; 2) generating a general explainer to recognize the said rule signs; 3) setting rule database unit according to a exact protocol; 4) when receiving the bit stream, the said explainer reads rule statement from rule database, executes every control action set by rule sign, and completes the analysis. When the protocol changes, it needs just to modify the rule database unit instead of the said explainer; thereby, the invention decreases modification time and analysis difficulty.

Description

technical field [0001] The invention relates to a protocol message analysis method and a protocol message analysis system in the communication field. Background technique [0002] In a communication system, the sender composes the content to be sent as a protocol message according to a certain wireless communication protocol, and the receiver analyzes the received protocol message according to the same wireless communication protocol to obtain the content to be sent. The protocol messages include standard protocol messages defined by protocol specifications and custom protocol messages developed by equipment vendors. [0003] When developing equipment, communication equipment manufacturers need to track and test the protocol messages of the equipment. By observing the communication process of these protocol messages and the detailed content contained in them, problems existing in the equipment can be found, and then the stability of the equipment can be measured. In additio...
