Problems solved by technology

This is achievable in the ASN.1 codec with a fixed encoding type, but it cannot achieve its general purpose in the TLV codec with an unfixed encoding type and continuous expansion.

Embodiment Construction

[0027] The purpose of the method of the present invention is to provide a method for implementing TLV encoding and decoding in a WiMAX system (base station, terminal), for building a simple, efficient, easy-to-implement, and easy-to-expand module to meet the needs of development based on 802.16e and Its subsequent protocol software requirements.

[0028] The basic principle of the inventive method is as follows:

[0029] For a message that requires TLV encoding, since it is described by C language, and the encoding and decoding rules are not limited to any programming language (that is, the encoding and decoding rules only conform to the TLV specification), the encoding program must first try to Transform the data structure described by the C language into a data structure conforming to the TLV grammar (mainly to determine the one-to-one correspondence between the data types in the two environments), and then use specific coding rules to start coding. On the contrary, for the...

Abstract

The invention relates to a method for implementing the codec of the WiMAX system message, which comprises the following steps: a TLV mapping table is defined and used for traversing different data structures; a primary data structure is structured according to the protocol and the primary data structure automatically generates the data structure into the format of the TLV mapping table by conversion and defines the corresponding static variables and the assignment mapping relationship between the TLV mapping table and the primary data structure in various codec functions; the types and the length elements in the TLV mapping table are judged and processed by traversing the TLV mapping table and the encoding and decoding of the whole message are accomplished. The method of the invention canimplement a TLV codec code module which is simple with high efficiency, and is easy to implement and extend.

Description

technical field [0001] The invention relates to a method for realizing TLV codec in a WiMAX system (base station, terminal), in particular to a method for realizing TLV codec for various management control messages conforming to 802.16e protocol. Background technique [0002] TLV (Type / Length / Value Object) codec is a codec rule very similar to BER (Basic Encoding Rules) codec in ASN.1 (Abstract Syntax Notation), and is widely used in the field of computer communication. It not only inherits the advantages of ASN.1, but also makes the high-level application data transmitted by the communication parties in the network platform-independent (the hardware has nothing to do with the machine, and the soft machine has nothing to do with the operating system and programming language), and has good scalability ; At the same time, it has a certain degree of flexibility. The type field in TLV codec is not limited to several broad data types in the ASN.1 abstract description syntax, but ...
