MAP的ASN.1编解码实现

The Realization Of ASN.1 Encoding/Decoding In MAP

抽象语法记法一(ASN.1)已被广泛应用于通信协议的描述,GSM移动应用部分(MAP)也使用了ASN.1来描述,并采用BER编码规则对协议传送数据进行编解码,但目前尚无针对MAP协议特点进行编解码的方案。为此,在改进通用的编解码方法的基础上,文章提出了一种优化后的MAP信令的ASN.1编解码方案,经过仿真验证其效率较通用编解码方案平均提高10%。

ASN. 1 （Abstract Syntax Notation One） has been widely used in communication-protocol description. The GSM-MAP is also described with ASN. 1 and Encoded/Decoded with its Basic Encode Rules（BER）. However, there is no specialized scheme forM AP protocol codec at present. Based on the universal encoding/decoding method, this paper puts forward an optimized encoding/decoding scheme forM AP protocol. Simulation has proved that it can improve efficiency by 10%.
