Problems solved by technology

[0023] In practical application, the above scheme has the following problems: According to the protocol specification TS25.213 of 3GPP, the scrambling codes of the E-RGCH, E-HICH and E-AGCH channels of each cell and the corresponding reference channel P-CPICH or S- CPICH has the same scrambling code
[0025] If the CRNC is allowed to directly configure the channel scrambling codes of E-RGCH, E-HICH and E-AGCH through the NBAP message "PHYSICAL SHARED CHANNELRECONFIGURATION REQUEST", and the directly configured scrambling codes are different from the reference channel scrambling codes for some reason, the NodeB will at a loss

Embodiment Construction

[0055] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0056]The reconfiguration process of the physical shared channel according to the first embodiment of the present invention is shown in FIG. 5 . In step 510, the CRNC sends a PHYSICAL SHARED CHANNEL RECONFIGURATION REQUEST (physical shared channel reconfiguration request) message to the Node B. The main difference between this message and the PHYSICAL SHARED CHANNEL RECONFIGURATION REQUEST in the prior art is that it does not contain IE "E-AGCH And E-RGCH / E-HICH FDDScrambling Code", this IE specifies a scrambling code for the E-DCH downlink physical control channel (including E-AGCH, E-RGCH and E-HICH). Because the IE "E-AGCH AndE-RGCH / E-HICH FDD Scrambling Code" is not transmitted in NBAP messages, the amount of information to be carried in related NBAP messages...

Abstract

The invention relates to a mobile communication field, discloses a physical shared channel reconfiguration method capable of ensuring accuracy of wireless downlink control channel configuration. In the invention, a base staion node uses scrambling code configuration E-RGCH, E-HICH and E-AGCH corresponding to a downlink reference channel of a physical shared channel, the scrambling code is configured in the base staion node before establishing a cell, and a scrambling code used by E-RGCH, EHICH and E-AGCH is forbidded to be directly configured by a CRNC via an NBAP message. During the reconfiguration process of the physical shared channel of the NBAP, the invention allows changing a reference channel of the physical shared channel of the cell.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to the configuration technology of wireless channels. Background technique [0002] The 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as "3GPP") was initiated by standard organizations such as Europe, Japan, South Korea, and the United States, with the aim of researching, formulating and promoting the Global System for Mobile communication (Global System for Mobile communication, referred to as "GSM") is a standard that is based on the development of the third generation mobile communication network. [0003] Two wireless enhancement technologies introduced by 3GPP are briefly described below: High Speed ​​Downlink Packet Access (HSDPA for short) and Enhanced Dedicated Channel (E-DCH for short). [0004] HSDPA is a downlink wireless enhancement technology introduced by 3GPP in Release 5. This technology is proposed to meet the asymmetrical ...
