The present invention relates to a method for calculating a line capacity of an interconnection network between a wired telephone network and a mobile telephone network. More particularly, a far-end method of interconnecting a wired telephone network and a mobile telephone network through an internal line of a wired telephone network is provided. An apparatus and method for calculating interconnection line capacity by designing and determining a connection type.

1 is a diagram illustrating a network configuration between a wired telephone network and a mobile telephone network in the related art.

In FIG. 1, a conventional Land to Mobile (LM) connection network configuration includes a wired telephone network including a single station exchange (100a, 100b, LE; Local Exchange), an interconnection gateway exchange (200a, 200b, IGS; Interconnection Gateway Switch), A mobile telephone network including a mobile gateway gateway (300a, 300b, MGS; Mobile Gateway Switch), a mobile telephone switch (400a, 400b, MSC; Mobile Switching center), a subscriber location registration device (500, HLR; Home Location Register) Is done.

This conventional network configuration is a fixed network path that is formed in the interconnection gateway switch of a wired telephone originating area and the mobile telephone network gateway exchange of the same area regardless of the location of the mobile telephone subscriber to which the interconnection between the wired telephone network and the mobile telephone network is received. Near-end connection type of structure.

The call processing procedure when the calling subscriber of the wired telephone network in the access network requests a call from the called subscriber of the mobile telephone network is as follows.

In the conventional access network, when an originating subscriber accommodated in a wired telephone network calls a called subscriber accommodated in a mobile telephone network, the end-station switching station 100a in which the originating subscriber is accommodated makes a call request to the interconnection gateway exchange 200a, and the interconnection is performed. The gateway switch makes a call request to the mobile telephone network gateway switch 300a located in the nearest place (same area). Subsequently, the mobile telephone network gateway switch 300a having received the call request inquires the subscriber location information stored in the subscriber location registration device 500 to determine which mobile telephone switch is received by the called subscriber. The call request is made to the second mobile telephone network gateway switch 300b that manages the locked mobile telephone switch 400b.

Through the above process, when a call request is transmitted to the mobile switching center 400b that accepts the called subscriber, the mobile telephone switch calls the called mobile subscriber to establish a short-range path of the LM call between the calling wired subscriber and the called mobile subscriber. .

However, the LM connection path set as described above has the following problems.

If an outgoing subscriber housed in a wireline network calls a called party housed in a mobile telephone network located in a different area than that of the subscriber, the LM connection path between the originating subscriber and the destination subscriber is in the same area as the gateway exchange of the wireline network in the area where the originating subscriber is located. Mobile phone network gateway switching period is set. After the mobile telephone network gateway switch inquires about the location of the called subscriber, the LM access path is established through the mobile telephone network gateway exchanges in another area to reach the mobile telephone network gateway switch in the region where the called subscriber is currently located.

The LM access path is always established only through the gateway in the originating area and the mobile phone network gateway in the same area, regardless of the network structure inside the wired telephone network in the originating area, and through the mobile phone internal network. It is set up to pass through the mobile telephone network gateway exchanges in other regions to reach the destination.

Therefore, the LM connection path set as described above is inefficient for the operation and investment of the interconnection facility between the wireline telephone network and the mobile telephone network, and the connection cost paid between the wireline network operator and the mobile telephone network operator is irrational.

An object of the present invention for solving the problems of the prior art, the LM connection path is established only through the wired telephone network gateway switch in the calling area and the mobile telephone network gateway switch in the same area when the call is connected from the wired telephone network to the mobile telephone network. Rather, the present invention provides an apparatus and method for designing an LM path configured as a mobile switching center in a destination area via local gateway exchanges in a wired telephone network, and calculating LM access line capacity according to the LM path improvement.

In order to achieve the above object, according to the present invention, a gateway switch of a wireline telephone network receives location information of a mobile telephone subscriber from a subscriber location registration device, and includes network configuration data, network facility data, and LM traffic data of the wireline telephone network and the mobile telephone network.

At this time, the first interconnection gateway exchange queries the subscriber location information stored in the subscriber location registration device 500 to determine to which mobile telephone exchange the incoming subscriber is accommodated. As a result of the determination, if the called subscriber is accommodated in the first mobile switching center 400a in the same area as the calling subscriber, the first interconnection gateway switch 200a makes a call request to the first mobile switching center 400a in the same area. . If, as a result of the determination, the called subscriber is accommodated in the second mobile telephone switch 400b in a different area from the calling subscriber, the first interconnect gateway switch 200a follows the path 700 inside the wired telephone network. The call request is made to the second mobile telephone exchange 400b of the region where the service is located.

When the call request is transmitted to the second mobile switching center 400b that accepts the called subscriber through the internal path routing process of the wired telephone network, the second mobile telephone switch calls the called mobile subscriber to connect with the calling wired subscriber. The remote path of the LM call between the incoming mobile subscribers is established.
