Embodiment Construction

[0023] In order to make the purpose, technical means and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The basic idea of ​​the present invention is: when the cell is updated, the RNC of the new cell notifies the NodeB of the original cell to stop scheduling users, and after the cell update fails, the RNC of the new cell notifies the NodeB of the original cell to continue scheduling users.

[0025] figure 1 It is a specific flowchart of the cell update method in the present invention. like figure 1 As shown, the method includes:

[0026] Step 101 , when the E_FACH user determines to perform cell update according to the PCCPCH receiving power of the neighboring cell, it sends a cell update message to the RNC of the new cell.

[0027] Step 102, after receiving the cell update message sent by the E_FACH user, the RNC of the new cell notifies the NodeB of the us...

Abstract

The invention discloses a cell-update method for E_FACH (enhanced-forward access channel) users, which comprises the following steps that: after a user determines that cell update is required to be performed and sends a cell update message to a new cell RNC (radio network controller), the new cell RNC notifies the NodeB of an original cell of the user to stop scheduling the user; after the new cell RNC sends a cell update acknowledgment message to the user, if the user completes the cell update, UE (user equipment) sends feedback information to the new cell RNC; after receiving the feedback information of the UE, the new cell RNC notifies the NodeB to delete the resources of the user in the original cell; and if the new cell RNC does not receive the feedback information of the UE within a preset time, the new cell RNC notifies the NodeB to continue to schedule the user. Through using the method disclosed by the invention, the waste of power resources can be reduced, and the situation that after the UE subjected to update failure is returned to the original cell, the NodeB of the original cell can continue to schedule the UE can be ensured.

Description

technical field [0001] The invention relates to cell update technology, in particular to a cell update method for E_FACH users. Background technique [0002] When an E_FACH (Enhanced Forward Access Channel) user searches for a cell with better signal quality at the edge of the cell, it will initiate a cell update process in the new cell. Specifically, the process includes: [0003] Step 1, the user sends a cell update (Cell Update) message to the RNC of the new cell. [0004] In step 2, the RNC replies a cell update confirmation (Cell Update Confirm) message to the user. [0005] After the user receives the confirmation message, the cell update is completed. [0006] In the above cell update process, the NodeB cannot obtain the information of the UE changing the cell at the first time, and may continue to schedule E_FACH users during the period when the cell update process is completed, but because the UE has updated the cell, it will not respond Scheduling by the NodeB ...
