Method for generating Uu interface message in wide-band CDMA mobile communication system

Abstract

The method for generating Uu interface message includes steps: (1) RNC prepares message of service configuration to trigger UE; (2) based on changing condition of each service parameter in step (1), RNC generates expected configuration of each protocol layer of UE; (3) base on current configuration of UE, RNC compares it with expected configuration in step (2), and collects changing condition of configuration parameters in each protocol layer; (4) based on the changing condition said in (3) to determine cell set to be filled in for configuring UE; (5) determining diagnostic cells for existent symbols of cells provided in step (4) in order to define usable types of simplest standard message. The method can control effective length of Uu interface message, saves bandwidth of Uu interface as well as ensure structuredness and expansibility for WCDMA mobile communication system to process.

Description

technical field [0001] The present invention relates to a Wideband Code Division Multiple Access (WCDMA for short) mobile communication system. Hereinafter referred to as RNC) processes related processes of various service configurations, and organizes a method for generating Uu interface messages when sending wireless interface (UE-UTRAN interface) (hereinafter referred to as Uu interface) messages to UE. Background technique [0002] In the WCDMA mobile communication system, the RNC device manages the radio resources of the radio access network. The UE enters the connection state through the Radio Resources Control (RRC) connection establishment process, and then the RNC sends a standard message to the UE through the Uu interface, and manages the radio bearer and other resources and configuration of the UE, so as to realize the service. Add, delete, configuration modification, and some other configuration functions. [0003] In view of the relative lack of wireless trans...

Problems solved by technology

Whether the parameters of the protocol layers in the above messages are configured or not will be explained in the message with a specific flag. For example, the cell group contained in the physical channel reconfiguration message is a subset of the radio bearer reconfiguration message, and its function can be used by wireless Bearer reconfiguration message replacement, just mark the position of the message that does not need to be filled in as non-existent, and for some fields that must be filled in but have not changed, directly copy the current configuration parameters without changing them; it should be noted that, In this case, although the selected message can complete the configured effect, it has redundant content

[0006] The 3GPP protocol defines the structure of the above types of Uu interface messages and the configuration functions that can be completed. However, for some service parameter changes, the specific message used to complete the parameter configuration function is not specified in the agreement. In principle, as long as It can provide complete configuration parameters, different messages may be used based on different configuration strategies, and the same configuration function can be completed

A known implementation method is to manually determine the implementation method for a specific process in software implementation and fix it in the software product. A problem with this method is that it lacks the necessary flexibility for new functional requirements, and There is a possibility that human-selected messages are not optimal
