Method and system for implementing communications between multiple subnets and MSC
First Claim
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.

Abstract
The present invention discloses a method and a system for implementing communications between multiple subnets covered by one physical Mobile Switching Center (MSC) and an MSC. The method includes the steps of: mapping one physical MSC to multiple logical MSCs, i.e. multiple virtual MSCs, and assigning a virtual MSC number to each virtual MSC, and setting relationship(s) between location area(s) covered by the virtual MSC and the virtual MSC number of each virtual MSC; transmitting location information of a terminal with the virtual MSC number during communications to implement communications among multiple subnets. During communication, since the terminal location is transmitted according to the virtual MSC number, it is possible to differentiate the terminals located in different subnets covered by a physical MSC, therefore the roaming and handover of the terminal between the subnets can be implemented; and the roaming limitation also can be implemented through the MSC List and VLR List.
