摘要： A wireless communication system includes one or more base stations able to divide resources between multiple network operators sharing the base station. A shared base station is configured to monitor a contribution to the load on the base station associated with network operators sharing the base station resources and to provide the determined contribution to the load to one or more other base stations for use in load balancing between the base stations.

摘要： A relay communications system is described in which a base station receives a request from an MME that an overload procedure be started or stopped. The base station inserts the identity of the MME into the request and forwards the modified request to a relay node. The relay node then initiates or terminates the overload procedure in accordance with the request for mobile telephones which the MME that made the request serves, but not for mobile telephones which the MME does not serve.

摘要： A system is disclosed in which a base station initiates a handover of a mobile relay node associated with the base station. The base station obtains information that identifies at least one further base station, and that indicates that the at least one further base station is capable of providing donor services to the mobile relay node. When the base station determines that the mobile relay node requires handover, it selects, from at least one cell of the at least one further base station identified by the obtained information, a target cell for handover of the mobile relay node, and performs handover of the mobile relay node to the selected target cell.

摘要： A communication system is disclosed in which am anchor base station receives, from a core network node, downlink data for a communication device. The base station attempts (e.g. by RAN-based paging) to initiate communication with the communication device, and when the communication device does not respond to the attempt to initiate communication, the base station sends a message to the core network node, the message requesting initiation of a paging procedure for the communication device (e.g. S1-based paging).

摘要： There is presented a method performed by a central unit of a distributed base station apparatus in a cellular communication system, as part of a change of a UE context from a source distributed unit to a target distributed unit. A first message is sent to the target distributed unit of the distributed base station apparatus. A second message is received, from the target distributed unit of the distributed base station apparatus. The second message includes configuration information for the target distributed unit which may be full or delta. A third message is sent to a further base station apparatus that contains the received configuration information for the target distributed unit and an indication of whether a full or a delta type of configuration, has been used.
