    Abstract: 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.

    Abstract translation: 描述了一种中继通信系统，其中基站从MME接收到启动或停止过载过程的请求。 基站将MME的身份插入到请求中，并将修改的请求转发给中继节点。 然后，中继节点根据对发起请求的MME服务的移动电话的请求而不是针对MME不服务的移动电话启动或终止过载过程。

    Abstract: 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.

    Abstract: 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).

    Abstract: 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.

    Abstract: A method is presented in which a central unit of a distributed base station apparatus in a cellular communication system sends to a distributed unit of the distributed base station apparatus a first message comprising an information element for requesting the distributed unit of the distributed base station to provide a current distributed unit configuration. The central unit receives, from the distributed unit of the distributed base station apparatus, configuration information for the current distributed unit configuration in a second message sent in response to the first message.
