Abstract:
Procedure for limiting the mobility area (MOA) of a terminal device in a wireless local loop environment comprising an access node (1) connected to a telephone exchange (2) and a base station (3; 3a, 3b, 3c) with a coverage area comprising one or more cells (4; 4a, 4b, 4c), said base station serving to transmit call signals between the access node and the terminal device (5), the procedure comprising defining in the access node (1) the mobility area for the terminal device (5) as a specified geographic area comprising the coverage area of at least one cell (4); and that locking the terminal device with the local loop is inhibited by the access node (1) if the cell from which the terminal device is trying to get locked is outside the mobility area.
