Transfer back in a wireless network to a restricted local access point from a global point of access restricted

摘要

Execution method in a wireless network (10), a transfer back between a point (26) of restricted local access point (18) of global access restricted, where the wireless network (10) includes at least one point (18, 20, 22) of unrestricted global access that is controlled by at least one first unit (12) traffic control which is connected to at least one point (18, 20, 22) access overall not restricted by a second unit (13) and traffic control at least one point (28, 36, 46) restricted local access that acts as an access point within the network (10) for mobile stations have registered with permission to use and which is controlled by the at least one first traffic control, the method being characterized by comprising the steps of: requesting, at a first point (26) restricted local access, performing a transfer to a first point (18) global access restring gone and to accomplish this, transferring at least one broadcast frequency and an identity code of base station (BSIC) to the first unit (12) control; contact, in the first unit (12) control, with the second unit (13) which controls the first point (18) of unrestricted global access so that the second unit (13) receives information that want a handoff from the first point (26) local access to the first point (18) unrestricted global access, said information including at least broadcast frequency and the identity code of base station (BSIC) of the first point (26) restricted local access to allow the second unit (13) traffic control determines that the first point (26) restricted local access is a future candidate access point; transferring, at the first point (26) restricted local access, a mobile station (32) to the first point (18) unrestricted global access to inform the mobile station (32) where in a structure of signal first point (18) of unrestricted global access is to transmit and receive through the first unit (12) for controlling traffic; wherein the second unit (13) control commands to the first point (18) unrestricted global access to add, in association with a specific call which a handover is performed, the broadcast frequency generally the first point (26) local access restricted to a list of frequencies (AMNL) in which normally 30 commands the mobile station to carry out measurements in handover situations.
