Abstract
During a wireless communication of data in which modems (21, 24) are in use, a method of handing off the communication link (32) is described. The communication link (32) is handed off from a source base site (22) to a target base site (23). An interworking function (33) is then transfered from a source interworking unit (25) to a target interworking unit (26) by transfering protocol status (42) such as transmission control protocol. A cut over (34) from the source modem (21) to a target modem (24) is conducted once the interworking function (33) is transfered.
