Abstract: A mobile radio communications device is used for use in a cellular network and arranged for reselection to a neighbouring cell as required, the device being a arranged to employ one of a plurality of measurement qualities as part of a cell-reselection procedure, wherein the measurement quantity employed is selected responsive to a characteristic of the neighbouring cell, such that the device can employ different measurement quantities for different neighbouring cells, and to a related method of operation, network device and signalling message structure.

Abstract: A cellular communication system is capable of supporting local access points with shorter communication ranges than macro cells within which they are positioned. When a user wishes to send a communication a request is sent to an access point. At the access point a determination is made as to whether or not the maximum capacity of the access point has been reached. If maximum capacity has been reached then a rejection signal is sent to the user equipment and the communication is redirected into the macro cell in which the access point is positioned.

Abstract: A method for redirecting communication requests made by user equipment (6,8) to an access point (2) in a cellular communication system is disclosed. The access point (2) has a shorter communication range than a macrocell in the system. The method comprises the steps of; sending a communication request from user equipment to the access point (2); determining whether the access point (2) has reached a maximum capacity; sending a communication rejection signal to the user equipment (6,8) if the access point (2) has reached maximum capacity; and redirecting the communication request into the macrocell in which the access point (2) is positioned wherein the macrocell and femtocell operate at the same frequency.

Abstract: The invention provides for a method of initiating inter-frequency measurements within a mobile radio communications device and including the step of inspecting by way of a network the load state of the cell in which the mobile radio communications device is located, and further including the step of paging the mobile radio communications device with a Paging Type 1 message indicating that the mobile radio communications device can perform inter-frequency measurement on the cells identified within SIB before responding to the paging signal.

Abstract: A microwave radio communications device is configured to communicate with a selected one of at least first and second base stations of respective first and second cells, the first cell having a greater area of coverage than the second cell. The device is configured to retrieve data from a BSID sent from each base station and serving to discriminate between signals from the said first and second base stations indicating the relative cell coverage. Thereby the device achieves selective registration to one of the base stations responsive to the said discrimination.

Abstract: A method for instigating a location/routing area update procedure (LAU/RAU) when a piece of user equipment (UE) reselects its communication base station from a macro base station to a shorter range base station positioned within a macro cell of the macro base station is disclosed. The method comprises the steps of establishing a radio resource control connection between the UE and the shorter range base station; registering the UE with the shorter range base station; assigning location area code data (LAC) and routing area code data (RAC) from the shorter range base station to the UE; wherein the LAC and RAC data are the same data as the LAC and RAC data provided to the UE by the macro cell base station, whereby the UE does not perform a LAU/RAU procedure when it moves out of range of the shorter range base station and recommences communication with the macro base station.
