Method for realizing communication among a plurality of subnets covered by one physical mobile switching center

Abstract

The invention discloses a method for realizing communication between multiple subnets covered by a physical MSC. The method comprises the following steps: virtualizing a physical MSC into multiple virtual MSCs, assigning a virtual MSC number to each virtual MSC, and The corresponding relationship between the location area number and the virtual MSC number is set in the system; the virtual MSC is used for communication, and the user's location information is transmitted according to the virtual MSC number during the communication process. Since the user's location information is transmitted according to the virtual MSC number during the communication process, the user's roaming between multiple subnets covered by a physical MSC and roaming restrictions are realized, and billing and traffic statistics are also realized according to the distance. The method overcomes the disadvantage in the prior art that services cannot be performed on different subnets within a network covered by a physical MSC.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for realizing communication between multiple subnets covered by a physical mobile switching center. Background technique [0002] In the networking of the mobile communication system, the division and network setting of the local network are generally determined according to the geographical location and user capacity. In sparsely populated areas, it is suitable to build a large-scale local network. Several small local networks can be set up in a large-scale local network, and connected nearby, which solves the problem of wide coverage. Wherein, the large local network refers to the entire network within the coverage of a physical mobile switching center (MSC), and the small local network refers to subnets divided by geographical location. [0003] A large local network consists of base stations, base station controllers, mobile switching centers, visitor location re...

Problems solved by technology

[0006] The problem caused by this is that in a network covered by a physical MSC, some services cannot be divided into subnets, and many services are difficult to carry out.

[0007] For example: in image 3 It is actually a long-distance call from a user in location area 2 to a user in location area 3, but it cannot be accurately judged by using an MSC number, which will c
