Abstract: A base station of a communications network includes a transceiver circuit configured to transmit signals in a first Radio Access Node (RAN) and signals in a second RAN, and a controller configured to deter mine if signals in the second RAN should be stopped based on a load of the first RAN.

Abstract: A communication system is described in which a base station operating in a hybrid or closed access mode requests deletion of the copy of the CSG-Id list maintained at the corresponding mobility management entity in the core network, when the base station changes its operation mode to an open (non-CSG) access mode.

Abstract: A communication system includes a communication network including a plurality of communication cells, a plurality of mobile communication devices each operable to connect into the communication network via at least one of the communication cells, and a communication apparatus for providing at least one of the communication cells. The communication apparatus is operable to provide first and second communication cells via which a mobile communication device can connect to a communication network and to determine whether a mobile communication device is connected to the communication network via the first and/or second communication cells. The communication apparatus is also operable to monitor for further communication cells in dependence on a result of the determination by the determining unit.

Abstract: A method performed by a home base station, the method includes registering with a gateway device, sending the gateway device data identifying whether or not the home base station includes an open access mode or a closed access mode home base station, receiving a request from a mobile communications device, transmitting a registration request for the mobile communications device to the gateway device, and receiving a registration accept message from the gateway device if registration of the mobile communication device is accepted.

Abstract: A communication system including macro and femto cells in which, during relocation of a mobile device from a source macro/femto cell to a target femto cell, mobile device capability, registration cause, and/or mobile device identity information available at the base station of the source macro/femto cell prior to relocation is made available to the home base station and gateway device of the target femto cell.

Abstract: A communication system in which an availability of communication resources to be used by a first base station module and a second base station module of a communications apparatus is managed. In one embodiment, the communication resources are shared between first and second base station modules such that communication resources that are not being used by the first base station module are available to be used by the second base station module and vice versa.

Abstract: A home base station registration request message includes data identifying whether or not the home base station comprises an open access mode or a closed access mode home base station.

Abstract: A communication system in which a transferring unit are configured for transferring at least one information element from a first base station to a second base station. In one embodiment, the information element is sent internally to a communication apparatus including the first and second base stations or externally via a communication node external to the apparatus. In one embodiment, the information element is sent between the two base stations via a communication node of a communication network.

Abstract: A communication system in which at least one of the first and second base station modules of a dual mode access point is configured to provide information, as regards to its operating mode, to the other base station module. In one embodiment, the operating mode information is provided via an internal interface coupling the first and second base station modules.

Abstract: A communication system includes a communication network including a plurality of communication cells, a plurality of mobile communication devices each operable to connect into the communication network via at least one of the communication cells, and a communication apparatus for providing at least one of the communication cells. The communication apparatus includes first and second base station functions each operable to acquire a congestion status and access control information for the other base station.

Abstract: A mobile communications system is described in which a mobile communications device can register with a Macro RAN base station or with a home base station when in range of the home base station. The home base station may be an open access mode, a closed access mode or a hybrid access mode home base station. The home base station sends a gateway device information about its access mode so that unnecessary access control is avoided. This information may be signalled to the gateway device by the presence or absence of an optional element of a registration request or by the presence or absence of entries within a mandatory element within the registration request.

Abstract: A communication system is described in which mobile telephones are able to roam between neighbouring home node base stations. Techniques are described for allocating U-RNTIs to mobile telephones by the home base stations or the home base station gateway. Techniques are also disclosed for target home base stations to be able to retrieve information needed to respond to a Cell Update request received from a mobile telephone.

Abstract: A communication system is described in which mobile telephones are able to roam between neighbouring home node base stations and in which the home base stations or the home base station gateway devices are arranged to aggregate “Unsuccessfully Transmitted DL Data Volume” determined by previous home base stations served by the gateway device. In this way, when a call is transferred away from the gateway device or is released, a total aggregated value of “Unsuccessfully Transmitted DL Data Volume” can be provided to the core network for billing purposes.

Abstract: A communication system comprising macro and femto cells in which, during relocation of a mobile device from a source macro/femto cell to a target femto cell, mobile device capability, registration cause, and/or mobile device identity information available at the base station of the source macro/femto cell prior to relocation is made available to the home base station and gateway device of the target femto cell.
