Embodiment Construction

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034]The embodiment of the present invention can be implemented by adding a serving cell update CFN information element in the information element structure of the radio link establishment request signaling, and this information element can be an optional information element. When the UE is handed over to a new Node B cell, or when it is switched to a target base station cell, if the serving cell needs to be updated to the base station cell, the serving cell updates the CFN to establish a radio link in the base station cell. The link establishment request signaling is valid, and the RNC sets the time for the Node B side to start the serving cell update through the serving cell update CFN. If the serving cell does not need t...

Abstract

The provided updating method and device for service subzone comprise: transmitting request contain update link frame cell for building wireless link from wireless network controller to BS, and updating the service subzone by the BS. This invention simplifies signaling procedure, reduces system delay, and improves process speed.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a control technique for updating a serving cell. Background technique [0002] High Speed ​​Downlink Packet Access (HSDPA: High Speed ​​Downlink Packet Access) is a technology proposed by 3GPP in the R5 protocol to meet the asymmetrical requirements of uplink / downlink data services. It is regarded as a broadband code The next step in the evolution of the WCDMA (Wideband Code Division Multiple Access) system can increase the transmission rate of wireless data download to 14.4Mbps under the existing WCDMA architecture. This technology is an important technology for improving downlink capacity and data service rate in the later stage of WCDMA network construction. Realize the sharing of channel code and transmission power in HSDPA, and choose technologies such as Adaptive Modulation Code (AMC: Adaptive Modulation Code), Hybrid Automatic Repeat Request (HARQ: Hybrid Automatic Rep...
