Abstract

A call connection management equipment for decreasing the required time from a call connection request to a call connection establishment in a wireless mobile communication network. This call connection management equipment registers generated call connection information to a connection registration part, and stores call connection history, such as connection count. The call connection management equipment uses the already registered connection information when the call connection history satisfies a predetermined condition, and generates a new connection information when the call connection history does not satisfy the predetermined condition. When the predetermined condition is not satisfied, the connection information is deleted. The connection information is also deleted when a wireless base station to accommodate a calling terminal is switched, or when an interface to accommodate a called terminal is switched.

Claims

1. A call connection management equipment for a communication network having a plurality of interface points which includes a first interface point connected to a calling terminal, a second interface point connected to a called terminal, and other interface points connected between said first interface point and said second interface point,

the connection between said first interface point and said calling terminal and/or between said second interface point and said called terminal between wireless connection, and

at least one of said plurality of interface points being provided with said call connection management equipment comprising:

a connection setter to generate call connection information concerning calling terminal ID, called terminal ID, and communication route between said first interface point and said second interface point;

a connection register including a connection management table registering said call connection information to said connection management table in a first case that said call connection information has not been recorded in said connection management table, and not registering said call connection information to said connection management table in a second case that said call connection information has been recorded in said connection management table; and

a connection establisher to establish a call connection between said calling terminal and said called terminal based on a new connection information generated by said connection setter in said first case , and to establish a call connection between said calling terminal and said called terminal based on said connection information registered in said connection management table in said second case.

2. The call connection management equipment according to claim 1, wherein said first interface is a wireless base station.

3. The call connection management equipment according to claim 2, wherein said second interface point is a gateway switch for connecting said wireless communication network and another communication network.

4. The call connection management equipment to claim 2, wherein said second interface point is a mobile communication controller.

5. The call connection management equipment according to claim 2, wherein said second interface point is a gateway switch for connecting said wireless communication network and another communication network.

6. The call connection management equipment according to claim 1, wherein said second interface point is a wireless base station.

7. The call connection management equipment according to claim 1, wherein said first interface point is a mobile communication controller.

8. The call connection management equipment according to claim 1, wherein said first interface point and said second interface point are ATM interfaces.

9. The call connection management equipment according to claim 1, wherein said connection register is adapted to delete the registration of said call connection information corresponding to said calling terminal from said connection management table when said first interface point to accommodate the calling terminal is switched.

10. The call connection management equipment according to claim 9, wherein said connection register is adapted to delete the registration of said call connection information corresponding to said calling terminal from said connection management table when a wireless base station to accommodate the calling terminal is switched.

11. The call connection management equipment according to claim 9, wherein said connection register is adapted to delete the registration of said call connection information corresponding to said calling terminal from said connection management table when a mobile communication controller corresponding to the calling terminal is switched.

12. The call connection management equipment according to claim 1, wherein said connection register is adapted to delete the registration of said call connection information corresponding to said called terminal from said connection management table when said second interface point to accommodate the called terminal is switched.

13. The call connection management equipment according to claim 12, wherein said connection register is adapted to delete the registration of said call connection information corresponding to said called terminal from said connection management table when a wireless base station to accommodate the called terminal is switched.

14. The call connection management equipment according to claim 12, wherein said connection register is adapted to delete the registration of said call connection information corresponding to said called terminal from said connection management table when a mobile communication controller corresponding to the called terminal is switched.
