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: A communication system is disclosed in which a number of procedures may be performed between user equipment, a base station, and/or the core network in the context of network slicing. The procedures support, for example efficient configuration of paging areas, roaming, access restriction, mobility, setting up of dual mode connectivity, connection re-establishment, efficient paging and slice selection.

Abstract: A system is disclosed in which a base station performs an Automatic Neighbour Relation (ANR) operation in relation to a Wireless Local Area Network (WLAN) and obtains, from a mobile communication device (UE) or a Mobility Management Entity (MME), the Transport Network layer (TNL) address associated with a WLAN Termination node of the WLAN for establishing a connection between the base station and the WLAN Termination node.

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 mobile communications system is described in which base stations can communicate with each other or with a central coordinator to exchange idle mode UE load information so that decisions can be made to change cell specific or frequency specific priorities used by different cells within the network to balance the loading of idle mode UEs between cells.

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.

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: 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: A communication system is disclosed comprising an X2 gateway, a number of base stations, and a mobile device. The base stations are able to establish X2 connections directly with each other or via the X2 gateway. Various procedures are disclosed to determine how X2 connections should be established based on compatibility of the respective base stations with the X2 gateway.
