Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] like figure 1 Shown, TD-SCDMA system layer three message of the present invention, the codec method of layer three message for short comprises the following steps:

[0024] Step 101: Read the message definition, and store the message structure and its member cell structures in the read message definition.

[0025] The definition of the message can come from the message definition file stipulated in the agreement, and can also come from the specific program setting, as long as the structure of the message complies with the regulations in 3GPP TS24.007 and 24.008.

[0026] After reading the message definition from the message definition file or other locations, store the message structure and member cell structure in the read message definition. The storage data structure can have various forms, such as: linked list form, array ...

Abstract

The prevent invention relates to a coding and decoding method for the information of the time division synchronous code multiplex access system layer. The method comprises the steps as follows: 1 read the information definition and store the information structure in the read information definition and corresponding member cell structure; 2 confirm the corresponding information structure format and member cell structure format of each stored information structure and each member cell structure and store the confirmed results to a file; 3. confirm the corresponding coding and decoding plan of each piece of information according to the information structure format and the member cell structure format; and 4 conduct coding and decoding operations to the specific information by making use of the coding and decoding plan. The coding and decoding method for the information of the time division synchronous code multiplex access system layer of the present invention can create uniform and standardized information structure formats and member cell structure formats as well as uniform and standardized information coding and decoding plans, being beneficial to the maintenances and upgrades ofsystems, and is applicable to the newly defined information classes.

Description

technical field [0001] The invention relates to the technical field of coding and decoding of messages in a communication system, in particular to a method for coding and decoding layer 3 messages of a time-division synchronous code division multiple access system. Background technique [0002] In the Time Division-Synchronization Code Division Multiple Access (TD-SCDMA, Time Division-Synchronization Code Division Multiple Access) system, the wireless interface is divided into three layers, namely: layer 1 physical layer, layer 2 data link layer and layer 3 network layer. Among them, layer 3 includes radio resource control (RRC, RadioResource Control) layer and other sublayers, responsible for the broadcast of system messages, the establishment, maintenance and release of RRC connections between user equipment and radio access network, the establishment and reconfiguration of radio bearers And release and allocation of wireless resources and other functions. Therefore, it i...
