Embodiment 1

[0084] Embodiment 1: In the process that the user terminal switches to the target HS-DSCH cell, the NBAP radio link reconfiguration message (Radio Link Reconfiguration Prepare or Radio LinkReconfiguration Request) is used to replace the SRNC sending to the base station of the target HS-DSCH cell in the prior art Radio Link Reconfiguration Commit message, and add a new information element in it, keep other steps the same as the prior art, the pre-configuration of its HSDPA information and the flow of service HS-DSCH cell handover, as shown in Figure 2:

[0085] Steps 1-8, the same as steps 1-8 of the process in Figure 1, are the pre-configuration process for HSDPA;

[0086] Step 9. After the UE measures the best cell change information, it sends a measurement report to the RNC (the measurement event is 1D);

[0087] Step 10, SRNC decides to switch over the serving HS-DSCH cell, sends a radio link reconfiguration message to the target Node B, carries the serving HS-DSCH cell ind...

Embodiment 2

[0093] Embodiment 2: In the process of switching the user terminal to the target HS-DSCH cell, use the original information element ServingHS-DSCH radio link indicator in the Radio Bearer Reconfiguration message sent to the user terminal by the SRNC to activate the HSDPA of the target serving HS-DSCH cell, and Deactivate the HSDPA of the source serving HS-DSCH cell, keep other steps the same as the prior art, the pre-configuration of its HSDPA information and the flow of serving the HS-DSCH cell handover, as shown in Figure 3:

[0094] Steps 1-8, the same as steps 1-8 of the process in Figure 1, are the pre-configuration process for HSDPA;

[0095] Step 9. After the UE measures the best cell change information, it sends a measurement report to the RNC (the measurement event is 1D);

[0096] Step 10, SRNC decides to switch over serving HS-DSCH cells, sends a radio link reconfiguration commit (Radio Link Reconfiguration Commit) message to the target Node B, and notifies the targ...

Embodiment 3

[0100] Embodiment 3: In the process that the user terminal switches to the target HS-DSCH cell, the Radio Link Reconfiguration Commit message sent by the SRNC to the base station of the target HS-DSCH cell in the prior art is replaced with an NBAP radio link reconfiguration message, and in it Add a new information element; and use the information element ServingHS-DSCH radio link indicator in the Radio Bearer Reconfiguration message sent by the SRNC to the user terminal to activate the HSDPA of the target serving HS-DSCH cell, deactivate the HSDPA of the source serving HS-DSCH cell, and maintain other steps The same as the prior art, the pre-configuration of its HSDPA information and the flow of service HS-DSCH cell handover are shown in Figure 4:

[0101] Steps 1-8, the same as steps 1-8 of the process in Figure 1, are the pre-configuration process for HSDPA;

[0102] Step 9. After the UE measures the best cell change information, it sends a measurement report to the RNC (the...

Abstract

This invention discloses one method for service high speed down common transmission channel HS-DSCH area switch, which comprises the following steps: service wireless network controller SRNC takes indication message during the area switch in front or back area or user terminals; after activating switch back aim service HS-DSCH area high speed down set interface of HSDPA and removing front source service HS-DSCH area of HSDPA.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a cell switching method of a service high-speed downlink shared transmission channel HS-DSCH. Background technique [0002] Starting from Release 5, the 3rd Generation Partnership Project (3GPP) provides a High Speed ​​Downlink Packet Access (HSDPA) mechanism to provide high-speed transmission of downlink packets on an air interface. It consists of High Speed ​​Downlink Shared Transport Channel (High Speed ​​Downlink Shared Channel, HS-DSCH), High Speed ​​Downlink Physical Downlink Shared Channel (High Speed ​​Physical Downlink Shared Channel, HS-PDSCH), High Speed ​​Downlink Shared Control Channel (Shared Control Channel for HS-DSCH , HS-SCCH) and HS-DSCH dedicated uplink physical control channel (Dedicated Physical Control Channel (uplink) for HS-DSCH, HS-DPCCH) interact to achieve. Its function process is: the Node B of the cell base station implements the scheduling alg...
