Abstract
The system includes a network having a base controller (30) and a mobile station (32). The base controller (30) has a packet measurement order unit (34) which causes a package measurement reporter (68) in the mobile station to provide a measurement report. This report is stored in a buffer (44) and compared with reference values on a reference unit (48). If a change of cell is warranted, a packet cell change order unit (50) issues a command which is recorded by packet cell change unit (58) of the mobile station to retune the transmitter and receiver (54 and 56) to a new cell. The mobile station also has a unit (64) which generates a package cell change request to the base controller (30) to initiate a package cell change order from the unit (50) when a change is warranted.
