Patent ID: 8638774

Claim:
A basestation, for use in a mobile communications network, the basestation comprising: a frequency synthesizer, for generating signals at desired frequencies; a packet data interface, for transmitting and receiving packet data signals over a wide area network; wherein the basestation is configured to determine an elapsed time since it last synchronized the frequency synthesizer to a master device; wherein the basestation is configured to request synchronization packet data signals from the master device when the elapsed time exceeds a predetermined hold-over period; wherein, when the elapsed time does not exceed the predetermined hold-over period, the basestation is configured to determine whether temperature conditions at the basestation meet a predetermined temperature condition threshold, and to determine whether a resynchronization is required for the frequency synthesizer to remain in synchronization; wherein the basestation is configured to request synchronization packet data signals from the master device when said temperature condition threshold is met; wherein the basestation is configured to synchronize the frequency synthesizer to the master device on receipt of the synchronization packet data signals from the master device; and wherein the basestation is configured to request the master device to stop sending synchronization packet data signals to synchronize the frequency synthesizer to the master device.
