摘要： A cellular communication system comprises an access point (101) which supports an underlay cell of a first cell on an underlay frequency using another frequency. A proximity detector (113) detects user equipment (109) in response to a wireless transmission therefrom, which uses a different transmission technology from a transmission of the cellular communication system. In response to the proximity detection, the access point (101) temporarily transmits a pilot signal on the first cell frequency. The user equipment (109) is then switched to the access point (109) and the underlay frequency in response to a detection indication from the user equipment (109) indicating that the pilot signal has been detected. Following the switch the access point (101) terminates the transmission of the pilot signal.

摘要： A cellular communication system includes base stations supporting macro cells and with unique cell scrambling codes within a region. The system further includes access points supporting underlay cells and with shared cell scrambling codes within the region. One or more of the access points or base stations comprise transmit means for transmitting an indication of at least a first shared scrambling code to a remote station. The shared scrambling code is shared by a plurality of access points. The remote station is arranged to receive the first shared scrambling code and to determine if a first signal using the first shared scrambling code is received. If the first signal is detected, a handover controller initiates a handover of the remote station to at least a first access point of the plurality of access points sharing the first shared scrambling code.

摘要： A cellular communication system comprises a first base station (103) supporting user equipments (101) in a first cell. A user equipment (101) is supported in the first cell by the first base station (103) and is arranged to transmit previous cell switch candidate data to the first base station (103). The previous cell switch candidate data comprises an indication of at least one cell switch candidate for at least one base station supporting the user equipment prior to the first base station (103). The first base station is arranged to receive the previous cell switch candidate data transmitted from the user equipment (101). The previous cell switch candidate data may be used for different purposes such as synchronization of cells or generation of suitable cell switch candidate lists, such as neighbour cell lists. In particular, the approach may allow an improved automated or semi-automated generation of neighbour cell lists for a dynamically changing cell layout.

摘要： A communication system comprises a first radio network supporting a first air interface standard and a second radio network supporting a second air interface standard. The second radio network comprises a network interface 401 which receives a handover request message from the first radio network to hand over a remote station 101 to the second network. A handover preference processor 405 receives a handover preference message including a preference indication for a radio network for the remote station. A load processor 409 determines a load indication for the second radio network and a load threshold processor 407 determines a handover load threshold for the remote station in response to the preference indication. A handover evaluation processor 403 determines whether to accept the handover in response to a comparison of the load indication and the handover load threshold.

摘要： A cellular communication system employs an air interface time frame structure comprising time frames divided into a plurality of timeslots. In the system, a timeslot configuration processor (115) comprises a timeslot configurator (203) which configures timeslots of the time frames as a first service type or a second service type. The first and second service type can be circuit switched or packet switched service types. A first processor (205) converting a first timeslot from the first service type to the second service type. The cellular communication system then supports at least one service of the second service type in the first timeslot. A second processor (207) converts the first timeslot from the second type to the first type in response to a first service type usage characteristic for a cell supporting the at least one service and a second service type usage characteristic for a plurality of cells. The invention can improve timeslot conversion performance and can specifically reduce the required number of timeslot conversions.

摘要： A communication system (100) comprises a core network (109) for routing data to and from radio networks. A first radio network supports a first air interface standard (e.g. UMTS) and comprises a first controller, such as an RNC (107), which can receive a handover preference message from the core network (109) and which can determine a handover in response to the handover preference message. The second radio network supporting a second air interface standard (e.g. GSM) and comprises a second controller, such as a BSC 111, which can receive the handover preference message from the core network (109) and which can determine a handover in response to the handover preference message. An interlayer handover controller sets a handover preference indication such that the first controller biases handover decisions towards a remote station being supported by the first radio network and the second controller biases handover decisions towards the remote station being supported by the second radio network.
