Communication system

摘要

A Home NodeB (HNB) is provided that can be triggered to dynamically change its operating radio parameters, such as its transmission frequency or its primary scrambling code without having to be rebooted and which communicates the changed operating parameters to the mobile user devices served thereby. In this way a seamless changeover of the operating parameters can be provided that is transparent to users. The HNB may be triggered to change operating parameters by the mobile operating network or by an internal procedure.

1. A home base station comprising:
an interface for interfacing with an operator network via a public network; transceiver circuitry operable to transmit wireless signals to and to receive wireless signals from a mobile user device in accordance with current operating radio parameters; a communications control module operable to control communications between the home base station and said mobile user device using said transceiver circuitry; and a parameter control module operable, in response to a trigger, to obtain new operating radio parameters and to reconfigure the transceiver circuitry with the new operating radio parameters, wherein the new operating radio parameters include one or more of: a new frequency and a new primary scrambling code (PSC), wherein said communications control module is operable to communicate with said mobile user device to inform the mobile user device of the new operating radio parameters, wherein said communications control module is operable to inform mobile user devices operating in a Connected mode or an Idle mode of a change, wherein said communications control module is operable to inform mobile user devices by broadcasting data relating to the change over a broadcast channel, and wherein said communications control module is operable to broadcast an update for a Neighbor Cell List, identifying a cell of the home base station as a neighbor with a new configuration.
