Abstract:
1. A method for implementing communications among multiple subnets that are covered by a physical Mobile Switching Center (MSC), comprising: mapping a physical MSC having a physical MSC number to multiple virtual MSCs that are logical MSCs within the physical MSC, wherein each virtual MSC corresponds to one of the subnets representing a specified location within the physical MSC; assigning, to each of the virtual MSCs, a virtual MSC number; setting relationships between the subnets corresponding to the virtual MSCs and the virtual MSC numbers assigned to the virtual MSCs; transmitting a virtual MSC number of one of the virtual MSCs that is currently visited by a mobile wireless terminal when the mobile wireless terminal implements communications; identifying a subnet that the mobile wireless terminal currently belongs to according to the virtual MSC number of the visited virtual MSC and the set relationship between the subnet that the mobile wireless terminal currently belongs to and the virtual MSC number of the visited virtual MSC; and implementing communications for the mobile wireless terminal over the identified subnet.
