Abstract: A cellular communication system comprises a network based radio bearer controller (123) which is arranged to control and manage the setup and operation of radio bearers. The radio bearer controller comprises a RAB processor (201) which is arranged to set up a plurality of user plane radio bearers for a user equipment (101). The plurality of user plane radio bearers all support a common service. The radio bearer controller (123) further comprises a link processor (203) which links the plurality of user plane radio bearers. The radio bearer controller (123) can process linked user plane radio bearers in relation to each other, for example by terminating all linked user plane radio bearers if a single radio bearer fails. The invention may be particularly suitable for a UMTS (Universal Mobile Telecommunication System) communication system supporting services using a plurality of UMTS user plane radio bearers.

Abstract: A cellular communication system comprises a base station which is arranged to support user equipments associated with a plurality of operators or Private Land Mobile Networks (PLMNs). The base station comprises a first unit determining a first operator/PLMN of the plurality of operators/PLMNs serving a first user equipment. A second unit then generates a first message comprising an indication of the first user equipment and an indication of the first operator/PLMN. The first message is transmitted to a management entity of a fixed network of the cellular communication system. The system may allow improved support for equipment sharing in cellular communication networks.

Abstract: A customer premises gateway includes a connection manager, a registration manager and data storage. The registration manager registers the user devices connected to the gateway at the customer premises and stores information for the registered user devices, including identities for the user devices, at the gateway. The connection manager is operable to provide Internet Protocol Multimedia Subsystem (IMS) services and non-IMS services via a broadband network to the user devices connected to the gateway. The connection manager is also operable to provide the IMS services and non-IMS services to the registered devices based on the information stored for the registered user devices.

Abstract: A communication system (100) determines whether to establish a point-to-multipoint communication or a point-to-point communication for conveyance of Multimedia Broadcast Multicast Service (MBMS) data based on a number of mobile stations (MSs) (102-104), both idle mode and maintaining an active connection, serviced by the system and subscribed to an MBMS service. The system, broadcasts (306) a control message that includes an access probability factor. In order to avoid overloading the system with responses to the control message, MSs maintaining an active connection ignore (506, 508) the control message while idle mode MSs determine (506, 512) whether to respond based on the access probability factor. The system compares (310) a number of received responses to a threshold and determines whether to establish a point-to-multipoint communication (312) or a point-to-point communication (322) based on the comparison. The system also adjusts (314, 330) the access probability factor based on the number of responses.

Abstract: A multimode customer premises gateway supports multiple different types of telecommunications signaling protocols to allow different types of user devices to connect to the gateway and access both Internet Protocol multimedia subsystem (IMS), and non-IMS services. The gateway includes a connection manager configured to provide a non-IMS user device connected to the gateway with access to an IMS service using an IP multimedia services identity module (ISIM) for the gateway. A protocol converter translates information between an IMS protocol and a non-IMS protocol to enable the connection manager to provide the non-IMS device with access to the IMS service. The connection manager is also configured to provide an IMS user device with access to the IMS service and to provide a non-IMS user device with access to a non-IMS service.

Abstract: The invention relates to handover of a subscriber unit (301,305) from a first cellular communication system (201) to a second cellular communication system (203). The first communication system is for example a UMTS communication system supporting a plurality of connections, and the second communication system is for example a GSM communication system supporting only a single connection. The handover comprises forming a handover connection 219 to the subscriber unit (301,305) through the second communication system and handing one of the connections under the first communication system over to this connection. Rather than dropping the remaining connections, they are entered into a holding state. After the handover, one of the connections on hold may be entered into an active state by associating the handover connection (219) with this connection.

Abstract: A communication system determines whether to establish a point-to-point or point-to-multipoint communication for conveyance of Multimedia Broadcast Multicast Services (MBMS) data based on a number of user equipments being serviced by the communication system for MBMS service. The system broadcasts an access probability factor in a control message to the user equipments. For a large number of MBMS users being counted, the method will select a point-to-multipoint broadcast. If the number of user equipments being counted is relatively small, the access probability factor is modified by a ratio of the number of point-to-point connections over the point-to-multipoint connections over the number of users being counted. The UE may need to join multiple base stations' in the counting procedure to obtain the system diversity gain.

The system broadcasts an access probability factor (154) in a control message to the user equipments. For a large number of MBMS users being counted (158), the method will select a point-to-multipoint broadcast (160). If the number of user equipments being counted is relatively small, the access probability factor is modified by a ratio of the number of point-to-point connections over the point-to-multipoint connections over the number of users being counted (174). The UE may need to join multiple base stations' in the counting procedure to obtain the system diversity gain.
