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 subnet that represents one or more location areas within the physical MSC;
assigning, to each of the multiple virtual MSCs, a virtual MSC number;
setting relationships between each subnet that represents one or more location areas within the physical MSC and each virtual MSC number;
receiving a location update request from a wireless mobile terminal, wherein the location update request comprises information of an original location area and a current location area of the wireless mobile terminal;
identifying a virtual MSC number of one of the virtual MSCs that is currently visited by the wireless mobile terminal, according to the current location area and the set relationship between each subnet that represents one or more location areas within the physical MSC and each virtual MSC number; and
transmitting the identified virtual MSC number of one of the virtual MSCs that is currently visited by the wireless mobile terminal when the wireless mobile terminal implements communications.

Abstract
The present invention discloses a method and a system for implementing communications between multiple subnets covered by one physical Mobile Switching Center and an MSC. The method maps the MSC to multiple virtual MSCs that are logical MSCs within the physical MSC, each virtual MSC corresponds to one subnet that represents one or more location areas within the physical MSC, assigns to each of the multiple virtual MSCs a virtual MSC number, identifies a virtual MSC number of one of the virtual MSCs that is currently visited by the wireless mobile terminal, according to the current location area and the set relationship between each subnet that represents one or more location areas within the physical MSC and each virtual MSC number, and transmits the identified virtual MSC number of one of the virtual MSCs that is currently visited by a terminal when the wireless mobile terminal implements communications.

6. A physical Mobile Switching Center (MSC) for implementing communications between multiple subnets that are covered by the physical MSC, comprising:
-
a map unit, configured to map the 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 subnet that represents one or more location areas within the physical MSC; an assign unit, configured to assign to each of the multiple virtual MSCs, a virtual MSC number; a set unit, configured to set relationships between each subnet that represents one or more location areas within the physical MSC and each virtual MSC number; a receiver, configured to receive a location update request from a wireless mobile terminal, wherein the location update request comprises information of an original location area and a current location area of the wireless mobile terminal; a determine unit, configured to identify a virtual MSC number of one of the virtual MSCs that is currently visited by the wireless mobile terminal, according to the current location area and the set relationship between each subnet that represents one or more location areas within the physical MSC and each virtual MSC number; and a transmitter, configured to transmit the identified virtual MSC number of one of the virtual MSCs that is currently visited by the wireless mobile terminal when the wireless mobile terminal implements communications.

7. A system for implementing communications between multiple subnets that are covered by one physical Mobile Switching Center (MSC), comprising the physical MSC and a Home Location Register (HLR);
-
the MSC, configured to map the 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 subnet that represents one or more location areas within the physical MSC, assign to each of the multiple virtual MSCs, a virtual MSC number, set relationships between each subnet that represents one or more location areas within the physical MSC and each virtual MSC number, receive a location update request from a wireless mobile terminal, wherein the location update request comprises information of an original location area and a current location area of the wireless mobile terminal, identify a virtual MSC number of one of the virtual MSCs that is currently visited by the wireless mobile terminal, according to the current location area and the set relationship between each subnet that represents one or more location areas within the physical MSC and each virtual MSC number, and transmit the identified virtual MSC number of one of the virtual MSCs that is currently visited by the wireless mobile terminal when the wireless mobile terminal implements communications; the HLR, configured to receive the virtual MSC number of one of the virtual MSCs that is currently visited by the wireless mobile terminal sent by the MSC. - View Dependent Claims (8, 9, 10)
