Abstract

A private mobile communication system is for providing a public network busy state information of a mobile communication terminal. The private mobile communication system for informing a call origination mobile communication terminal of a public network busy state of a mobile communication terminal registered in a mobile communication system includes an HLR (Home Location Register) having a parameter indicating a public network busy state with respect to each mobile communication terminal registered in a private mobile communication system, and a message routing module for setting up a public network busy state of the mobile communication terminal in the case where the mobile communication terminal performs a call origination or a call reception over a public mobile communication network within a private mobile communication network.

Claims

1. A private mobile communication system interworking with a public mobile communication network, comprising:

at least one mobile communication terminal registered in said private mobile communication system;

a home location register including a public network busy state value indicating call connection with the public mobile communication network of the mobile communication terminal; and

a message routing module changing the public network busy state value registered in the home location register according to call connection with the public mobile communication network of the mobile communication terminal.

2. The private mobile communication system as set forth in claim 1, with said message routing module setting up a public network busy state value of a mobile communication terminal of said home location register when the mobile communication terminal in a public network busy state is handed off from the public mobile communication network to a private mobile communication network.

3. The private mobile communication system as set forth in claim 1, with said message routing module clearing a public network busy state value of a mobile communication terminal of said home location register when the mobile communication terminal closes a call connection state within a private mobile communication network.

4. The private mobile communication system as set forth in claim 1, with said message routing module determining the mobile communication terminal being out of a private mobile communication network when the mobile communication terminal in a public network busy state is handed off from the private mobile communication network to the public mobile communication network.

5. The private mobile communication system as set forth in claim 2, with said message routing module clearing a public network busy state value of the mobile communication terminal of said home location register when the mobile communication terminal closes a call connection state within the private mobile communication network.

6. The private mobile communication system as set forth in claim 5, with said message routing module determining the mobile communication terminal being out of the private mobile communication network when the mobile communication terminal in a public network busy state is handed off from the private mobile communication network to the public mobile communication network.

7. The private mobile communication system as set forth in claim 1, further comprising a call origination mobile communication terminal originated through a private mobile communication network being informed of a public network busy state of the mobile communication terminal.

14. The method as set forth in claim 7, further comprised of accommodating a private mobile communication system informing a call origination mobile communication terminal originated from the private mobile communication network of a public network busy state of the mobile communication terminal.

15. The private mobile communication system as set forth in claim 1, with said message routing module further clearing the public network busy state of a mobile communication terminal of said home location register when registering a location of the mobile communication terminal.

16. The private mobile communication system as set forth in claim 1, with said message routing module further clearing the public network busy state value of a mobile communication terminal of said home location register when the call identification information is identical with an index and the identification information of the mobile communication terminal is different than the index.

17. The private mobile communication system as set forth in claim 1, with said message routing module clearing a public network busy state of the mobile communication terminal when the mobile communication terminal originates or receives a call of a private network within the private mobile communication network.

8. A method, comprising:

registering in a home location register a public network busy state value indicating call connection with a public mobile communication network of a mobile communication terminal; and

changing the public network busy state value registered in the home location register according to a call connection with the public mobile communication network of the mobile communication terminal.

9. The method as set forth in claim 8, with said act of setting up the public network busy state being made by a message routing module.

10. The method as set forth in claim 8, with said act of setting up a public network busy state value of a mobile communication terminal of said home location register being when the mobile communication terminal in a public network busy state is handed off from a public mobile communication network to a private mobile communication network.

11. The method as set forth in claim 8, further comprising of clearing a public network busy state value of a mobile communication terminal of said home location register when the mobile communication terminal closes a call connection state within a private mobile communication network.

12. The method as set forth in claim 8, further comprising of determining the mobile communication terminal being out of a private mobile communication network when the mobile communication terminal in a public network busy state is handed off from the private mobile communication network to the public mobile communication network.

13. The method as set forth in claim 10, further comprising of clearing a public network busy state value of the mobile communication terminal of said home location register when the mobile communication terminal closes a call connection state within the private mobile communication network.
