Abstract

PURPOSE:To eliminate necessity for connecting respective traveling object exchanges by a direct line in the shape of a network by connecting an incoming call connecting request to a traveling machine from the traveling object exchange, to which the request is transmitted, through a general telephone network to the traveling object exchange in an active area station. CONSTITUTION:When identification information ID are returned from a traveling object exchange 20-3 in the active area, a follow connection setting means 700 assembles a follow connection number DN including active area station information and the identification information ID to identify the traveling object exchange 20-3 in the active area and sends the number out to a general telephone network 1. When receiving the follow connection number DN including the number of the station in the area to identify its own traveling object exchange 20-3 from the general telephone network 1, an incoming call connection setting means 800 sets incoming call connection to a call incoming traveling machine 25 based on incoming call connection information TD, which are already registered, corresponding to the identification information ID included in the follow connection number DN. Thus, it is not necessary to connect the respective traveling object exchange by the direct line in the shape of the network and a traveling object telephone network can be smoothly enlarged.

[Problem to be solved by the invention]

As is clear from the above explanation, in a conventional mobile telephone network, the closest station mobile switching system (GAMS) 20- 1 had to be connected through a direct line 31 in order to request an incoming call connection to the VAMS 20-3.

Therefore, it is necessary to connect all the mobile exchanges 20 that make up the mobile phone W42 in a network through direct lines 3, and the increase in the number of direct lines 3 and the decrease in line efficiency will cause problems in the mobile phone network 2. There was a risk that economic efficiency would be impaired. Furthermore, each time a new mobile exchange 20 is installed, it is necessary to install a direct line 3 between all the existing mobile exchanges 20. In order to install a direct line 3 between the mobile phone network 20 and the mobile phone network 20, additional construction work is required, which increases the construction cost, which poses a problem in that it hinders the expansion of the mobile telephone network 2.

An object of the present invention is to enable expansion of a mobile telephone network as smoothly as possible.

[Means to solve the problem]

FIG. 1 is a diagram showing the principle of the present invention.

In FIG. 1, 1 is a general telephone network, 2 is a mobile telephone network to which the present invention is applied, 20 is a mobile exchange that operates the mobile telephone network 2, and 25 is a mobile station.

500 is an incoming connection information transfer means provided in the mobile exchange 20 according to the present invention.

Reference numeral 600 denotes identification information transfer means provided in the mobile exchange 20 according to the present invention.

Reference numeral 700 denotes a tracking connection setting means provided in the mobile exchange 20 according to the present invention.

800 is an incoming connection setting means provided in the mobile exchange@2o according to the present invention.

[Effect]

Each mobile exchange 20 makes a call/receive connection to a mobile station 25 existing within its own communication range.

When the incoming connection information transfer means 500 receives an incoming connection request for the mobile device 25 from the general telephone network 1, the incoming connection information transfer means 500 transmits incoming connection information TD necessary for incoming connection to the incoming mobile device 25.
The call is forwarded to the serving mobile exchange 20-3 where the called mobile station 25 exists.

When the identification information transfer means 600 receives the incoming connection information TD regarding the mobile device 25 existing within the communication range of the own station, the identification information transfer means 600 assigns and registers the identification information ID to the incoming connection, and also assigns the identification information ID to the incoming connection. The information TD is returned to the transfer source mobile exchange 20-1.

The tracking connection setting means 700 connects the local mobile main switch 20-3.
When the identification information rD is returned from the local mobile exchange 20-3, a tracking connection number DN including the local station information and identification information ID for identifying the local mobile exchange 20-3 is assembled and sent to the general telephone network 1.

When the incoming call connection setting means 800 receives the tracking connection number DN including the local station number for identifying the own mobile exchange 20-3 from the general telephone network 1, the incoming call connection setting means 800 corresponds to the identification information ID included in the tracking connection number DN. Based on the registered terminating connection information TD, a terminating connection to the terminating mobile device 25 is set.

Therefore, from the mobile exchange that has received the incoming call connection request from the general telephone network to the mobile station,
Since the connection is made via the general telephone network, there is no need to connect each mobile exchange through a network of direct lines, making the mobile telephone network more economical, and when installing a new mobile exchange. Since no additional installation work is required for the mobile telephone exchange, the installation work becomes economical, and the mobile telephone network can be smoothly expanded.
