Synchronization in a mobile communications network
First Claim
1. A basestation, for use in a mobile communications network, the basestation comprising:
- a frequency synthesizer, for generating signals at desired frequencies;
a wireless communications interface, for transmitting and receiving signals in the mobile communications network; and
a packet data interface, for transmitting and receiving packet data signals over a wide area network,wherein the basestation is adapted to receive a signal from a first other basestation of the mobile communications network over said wireless communications interface, and to synchronize the frequency synthesizer with the signals received from the first other basestation of the mobile communications network; and
wherein the basestation is adapted to transmit a signal to a second other basestation of the mobile communications network over said packet data interface, such that the second other basestation of the mobile communications network is able to synchronize its frequency synthesizer with the signals transmitted from the basestation.

Abstract
A basestation, for example a femtocell basestation for use in a mobile communications network, has a frequency synthesizer, for generating signals at desired frequencies, and also has a wireless communications interface, for transmitting and receiving signals in the mobile communications network. The femtocell basestation also has a packet data interface, for transmitting and receiving packet data signals over a wide area network. The basestation is adapted to receive a signal from a first other basestation of the mobile communications network over the wireless communications interface, and to synchronize the frequency synthesizer with the signals received from the first other basestation of the mobile communications network, and to transmit a signal to a second other basestation of the mobile communications network over the packet data interface, such that the second other basestation of the mobile communications network is able to synchronize its frequency synthesizer with the signals transmitted from the basestation.

5. A management node for a mobile communications network, the network comprising a plurality of basestations, and each of said basestations comprising:
-
a frequency synthesizer, for generating signals at desired frequencies; and a packet data interface, for transmitting and receiving packet data signals over a wide area network, wherein the management node is adapted to receive signals from said basestations, said signals indicating whether the respective basestations have been able to achieve synchronization of their respective frequency synthesizers; and wherein the management node is adapted to transmit commands to selected basestations of the mobile communications network, such that, in response to said commands, each of the basestations of the mobile communications network is able to achieve synchronization of its respective frequency synthesizer. - View Dependent Claims (6, 7, 8, 9, 10)
