Abstract: A communication system is disclosed in which an anchor base station configures a RAN based paging area for a communication device. When the anchor base station determines that it is necessary to update the RAN based paging area, it seeks to inform the communication device indicating that the RAN paging area for the communication device needs to be updated at the communication device, and subsequently, the base station may broadcast system information comprising information identifying a change to the paging area (e.g. a removal of a cell). The broadcasting of system information may also be carried out in other cells of the paging area.

Abstract: The application relates to an interface setup procedure to set up an interface between a communication apparatus of a cellular communication system and a communication apparatus of a wireless local area network (WLAN). The communication apparatus of the cellular communication system and the communication apparatus of the WLAN communicate in pursuance of an interface setup procedure to set up an interface between them. Accordingly, the communication apparatus of the cellular communication system transmits an interface setup request message to the communication apparatus of the WLAN; the communication apparatus of the cellular communication system, responsive to said interface setup request message, receives from the communication apparatus of the WLAN an interface setup response message which comprises information identifying an access mode of at least one access point (AP) of the WLAN; and the interface is then set up at the communication apparatus of the cellular communication system and at the communication apparatus of the WLAN.

Abstract: A system is described in which a default mobility management entity (MME) receives, from a base station, a request for setting up a communication connection to a mobile device having an associated usage type. The default MME sends, to the base station and responsive to the request, a message identifying a dedicated MME, to which the request should be re-routed, the dedicated MME having a supported service type corresponding to the usage type associated with the mobile device. The base station sends a response to the default MME, the response indicating whether re-routing to said dedicated MME is was successful or not (e.g. due to an overload of the dedicated MME). If the re-routing was not successful, the default MME attempts to serve the mobile device instead of the dedicated MME.
Abstract translation: 描述了一种系统，其中默认移动性管理实体（MME）从基站接收到具有相关联的使用类型的移动设备建立通信连接的请求。 默认MME向基站发送响应于该请求的消息，该消息标识应该重新路由该请求的专用MME，具有与移动设备相关联的使用类型对应的受支持服务类型的专用MME 。 基站向默认MME发送响应，指示到所述专用MME的重路由的响应是否成功（例如由于专用MME的过载）。 如果重新路由不成功，则默认MME尝试为移动设备而不是专用MME服务。

Abstract: A communication system is disclosed comprising a gateway, a number of base stations, and a mobile device. The gateway holds information mapping address data for each base station to information identifying a respective cell operated by that base station. A base station obtains information identifying a cell operated by a neighbour base station and provides this information to the gateway. The gateway obtains from the information held address data for the neighbour base station based on the information identifying the cell operated by the neighbour base station. The gateway generates and sends a message including address data to the base station. The base station receives the message and establishes a connection with the neighbour base station using the address data.

Abstract: A communication system is disclosed in which a communication device forms part of a communication system in which network slicing is supported and in which at least one tenant is able to communicate using at least one slice type associated with that tenant. The communication device receives network slicing related information transmitted by a base station. The network slicing related information may comprise information identifying support for a tenant whose communication is supported via the base station, or a network slice type of a tenant that is supported by the base station. The network slicing related information may comprise information comprising at least one communication parameter that is associated with a specific tenant or a specific slice type of a specific tenant. The communication device uses a slice having a slice type of a tenant with which the communication device is associated, based on the network slicing related information.
