Embodiment Construction

[0028] The embodiment of the present invention provides a HSDPA handover processing method and device. The embodiment of the present invention modifies the IUB message structure so that the NODEB actively informs the RNC whether the cell supports HARQPREAMBLE.

[0029] The processing flow of the method described in the embodiment of the present invention is as follows figure 1 shown, including the following steps:

[0030] Step 1-1. Modify the IUB message structure, and add an option indicating whether the cell supports HARQPREAMBLE.

[0031] The embodiment of the present invention first modifies the IUB message structure, and adds an option in the IE (InformationElement, information element) of the HARQ Preamble Mode Activation Indicator (HARQ Preamble mode activation indication) in the IUB: HARQ Preamble Mode Inactivated, through the HARQ Preamble Mode Inactivated option Take the value to indicate whether the cell supports HARQ PREAMBLE.

[0032] The HARQPreamble Mode Ina...

Abstract

The invention provides a processing method for high speed downlink packet access switching and a device thereof. The method essentially comprises the steps that: an NODEB (base station) sends a message that whether a small area supports HARQ PREMBLE (hybrid automatic repeat request premble) to an RNC (radio network controller); the RNC selects a corresponding channel analysis manner to communicate with the NODEB according to the message that whether the small area supports HARQ PREMBLE. By utilizing the method and the device of the embodiment of the invention, the RNC can select the corresponding channel analysis manner to communicate with the NODEB according to the message that whether the small area supports HARQ PREMBLE, thereby improving the HSPDA switching proposal of a radio link ofUE.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a HSDPA (High Speed ​​Downlink Packet Access, High Speed ​​Downlink Packet Access) switching processing method and device. Background technique [0002] HSDPA is an enhanced technology introduced in the R5 protocol by 3GPP (Third Generation Partnership Projects) to increase downlink capacity and data service rate. HSDPA can increase the downlink data service rate to 10Mbps without changing the existing WCDMA (Wideband Code Division Multiple Access) network structure. [0003] Currently, HSDPA supports HARQ PREAMBLE (Hybrid Automatic Repeat Packet Header Synchronization). However, in some specific scenarios, according to the message structure of IUB (interface between NODEB and RNC), NODEB (base station) cannot correctly inform RNC (Radio Network Controller, radio network controller) whether the current user's link supports HARQ PREAMBLE , and finally make the rate ...
