Embodiment Construction

[0031] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0032] The present invention unifies all protocol versions supported by the UE in the ASN.1 structure to the highest protocol version it supports, and the UE only needs to process the highest protocol version without considering the processing of different protocol versions. The specific steps are:

[0033] (1) Classify all IEs according to whether the information element (Information Element, IE) in the ASN.1 structure has changed in the version evolution:

[0034] a) the information elements contained in the message of the highest protocol version are classified as type A;

[0035] b) The lower version information element of the information element contained in the message of the highest protocol version, and all the contents of the information element are included in the highest protocol version of the information element, classified ...

Abstract

The invention provides a method for realizing the forward compatibility of protocol versions in a 3G RRC ASN.1 structure at the UE (user equipment) side, which comprises the following steps: classifying all information elements in a 3G RRC ASN.1 structure according to the situation that whether information elements in a 3G RRC ASN.1 structure are changed in the process of version evolution; generating header file analysis tools and coding / decoding analysis tools according to the classification of the information elements; analyzing an ASN.1 structure by using the header file analysis tool so as to generate header files related to a build environment; and generating a code for realizing message coding / decoding by using the coding / decoding analysis tools and the header files related to the build environment. According to the scheme provided by the invention, normal communication between the UE and networks in different protocol versions can be realized under the condition of no network protocol version information without a plurality of sets of implementation codes and any additional manual interventions, thereby greatly reducing the maintenance cost of the codes and improving the flexibility of a protocol.

Description

technical field [0001] The invention belongs to the technical field of the third generation mobile communication, and in particular relates to a method for realizing the forward compatibility of the protocol version in the ASN.1 structure in the third generation mobile communication radio resource management (3G RRC) at the UE side. Background technique [0002] Abstract Syntax Notation One (ASN.1) is mainly used for exchanging PDUs between two protocol entities. The version of ASN.1 can be extended, including non-critical extension (Non Critical Extension) and key extension (Critical Extension). A common way to add key extensions is to define a new version of the message, thus forming a new ASN.1 protocol version. [0003] Protocol messages of multiple interfaces in the third generation mobile communication system, including radio resource control (RRC) messages of the air interface, all use ASN.1. With the continuous development of the system, the 3rd Generation Partners...
