Abstract
In a communication system (10) which includes a communication unit (56) (CU), a Mobile-Switch Interface (50) (MSI), and a Mobile services Switching Center (40) (MSC), a method for location registration and call continuation involves the MSI (50) determining (174) whether the CU (56) intends to utilize a system service after the CU (56) completes a location updating process without releasing a channel between the CU (56) and the MSC (40). When the CU (56) does intend to utilize the system service directly after the location updating process, the MSI (50) allows the CU (56) to utilize the system service regardless of whether the MSC (40) indicated that the CU (56) cannot utilize the system service without first releasing the channel.
