Abstract:
1. A method of transferring anchor carrier status from a first carrier to another carrier in a multi-carrier wireless telecommunications network, the multi-carrier wireless telecommunications network comprising a base station and user equipment operable to simultaneously transmit and receive signals on more than one radio frequency carrier within a sector of the telecommunications network, the method comprising: receiving details of a triggering event to be notified to a network node; the triggering event comprising a change in a measurable characteristic of the first carrier past a predetermined first threshold value; providing triggering information indicative of the triggering event to a network node; determining which of the other carriers of the multi-carrier telecommunications network have a measurable characteristic past a predetermined second threshold value; providing information relating to carriers determined to have a measurable characteristic past the predetermined second threshold value to the network node; and transferring anchor carrier status, in response to a received signal generated in response to receipt of the information relating to carriers determined to have a measurable characteristic past the predetermined second threshold and the triggering information, to one of the carriers determined to have a measurable characteristic past the predetermined second threshold value.
