Embodiment Construction

[0065] The present invention provides a kind of call history record (CHR), and this record can track the problem that occurs in the RAB establishment process, and feeds back to the network management system through the standard protocol message, and the network management system analyzes the problem that calls occur according to these historical records, And analyze the problem through these message cells, and recover the fault through corresponding means.

[0066] The RAB assignment process includes the RAB establishment, modification and release process. The following uses the RAB establishment (DCH to DCH-synchronization) as an example to illustrate the protocol process, such as figure 2 shown, including the following steps:

[0067] 1. The CN sends a RAB assignment request (RAB ASSIGNMENT REQUEST) message to the SRNC. The message includes RAB parameters, user plane mode and transport layer related information, and the SRNC provides user radio layer and transport layer res...

Abstract

Characters of the invention are as following: establishing parameter information set of RAB assignation fault; in the said parameter information set, setting up reporting parameter items of the parameter information set of RAB assignation fault. When establishing RAB assignation, the method includes following steps: (1) monitoring RAB assignation connection, and receiving fault information sent by system when radio resources control (RRC) connection is in failure; (2) based on fault cause pointed out by fault signal to query parameter item required to report in information set of RAB assignation fault; (3) based on the said parameter item to obtain corresponding parameter value from system, and to write the value to message of reporting fault; (4) sending the message of reporting fault to network management center. The invention can obtain specific cause of RAB assignation fault so as to solve issue of RAB assignation fault.

Description

technical field [0001] The invention relates to a mobile communication system, and particularly discloses a method for reporting RAB assignment faults in a WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) system. Background technique [0002] The WCDMA system is an open system, which mainly includes CN (Core Network, core network), UTRAN (UMTS Terrestrial Radio Access Network, UMTS Terrestrial Radio Access Network), and UE (User Equipment, user terminal) three parts (other Parts such as network management and alarm station are not listed in this patent description). Among them, the RNC (Radio Network Controller, radio network controller) belongs to the UTRAN part. There are standard interfaces between the RNC and other network elements, such as the IU interface with the CN, the IUB interface with the NodeB, and the IUB interface with other RNCs. The IUR interface, and of course the interface between the UE and the RNC is the UU interfac...
