Problems solved by technology

Using this method will greatly reduce the processing speed of the wireless network, thereby affecting the performance of the entire network
[0011] In the 3GPP agreement, only the encoding algorithm is given, but the specific encoding process and method are not clearly given.
And there is no technical solution to solve the problem of multiple encoding at present

Embodiment Construction

[0068] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0069] Such as figure 1 As shown, for basic network services, the present invention encodes the air interface message as follows:

[0070] Step 110, save the Messagesequence number in the Integrity check info information in the air interface message to be encoded, and set it to 0;

[0071] Step 115, recording the byte position and bit offset of the beginning of the integrity coding information in the coded stream;

[0072] Step 120, the Message authentication code (Mac, message authentication code) in the Integrity check info information is set as the SRB used by the message to encode the integrity check information;

[0073] Step 125, encode the entire air interface message;

[0074] Step 130, if the encoding is successful, go to step 135; if it fails, go to step 190;

[0075] Step 135, calling the F9 algorithm to generate an integrity code;

[0076] St...

Abstract

This invention discloses a wideband CDMA system empty information coding method, relating to the empty information coding method; to address the existing empty information coding being tedious, and the invention includes following steps: (1) processing a complete coding to the empty information, and meanwhile storing the part that need re-coding, and its location information in the coded empty information code flow; (2) according to the location information of the needed re-coding part, doing re-coding. In the empty information coding process, the invention uses ASN1 PER coding features and the inherent characteristics of some message elements in the empty information, using the partial coding method, reducing the coding times, improving the coding efficiency, reducing the system resources occupation and the business processing time, and improving the system processing capacity and performance. This invention applies in particular to the coding process of empty information in CDMA system.

Description

technical field [0001] The invention relates to a coding method in a 3G (third generation) mobile communication system, in particular to a coding method for an air interface message in a wideband code division multiple access system. Background technique [0002] The WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) system adopts the compact encoding rule (PER, Pacted Encoding Rule) method of the abstract syntax specification (ASN1, Abstract Syntax Notation One). The minimum coding unit can maximize the lossless compression information coding length, so as to save transmission resources. ASN1 is a set of rules used to describe data structures and their encoding, and is widely used in the description of data structures in RFC (Request For Comments) texts. [0003] In the WCDMA system, in order to ensure the reliable transmission of air interface messages, it is necessary to check the integrity of the messages used for transmission between...
