摘要

A telecommunications network comprises a base station and a mobile station in use in call connection on at least one uplink channel for communicating user data. The base station is operative such that on receipt of a command to transfer to and/or add at least one other uplink channel for communicating user data, the at least one other uplink channel is allocated to the call connection after a predetermined period during which power level adjustment is undertaken to compensate for mobile station movement.
