ACTIVATION TIME FOR TARGET BASED HIGH SPEED SERVING CELL CHANGE

摘要

The present solution relates to a method in a user equipment (310) for setting up an activation time of a cell change of the user equipment (310) from a serving cell (305) to a target cell (308) in a wireless communications network (300). The user equipment (310) receives (501) a timing offset from a network controller (315), calculates (502) a cell change activation time based on the timing offset and transmits (503) the calculated activation time to the network controller (315). Then, the user equipment (310) receives (504) an approval of the cell change from the network controller (315) and moves (505) from the serving cell (306) to the target cell (308) at the activation time if the approval has been received.

1. A method in a user equipment for setting up an activation time of a high speed downlink shared channel cell change of the user equipment from a first cell to a second cell in a wireless communications network, the method comprising:
receiving a timing offset from the wireless communications network through broadcast or dedicated signalling at call setup; calculating a high speed downlink shared channel cell change activation time based on the received timing offset, the activation time indicating when the user equipment can perform a cell change from the first cell to the second cell; transmitting the calculated activation time from the user equipment to the wireless communications network; receiving an approval of the downlink shared channel high speed cell change from the wireless communications network; and performing a cell change from the first cell to the second cell at the activation time if the approval has been received.
