Abstract

A system for wireless communication is provided that includes a mobile switching center and a communication component, such as a base station or an access network. The mobile switching center is operable to transmit a message identifying a mobile station to be released. The communications component is operable to receive the message from the mobile switching center. The communications component is further operable to identify and release the mobile station based on the message.

Claims

1. A system for wireless communication, comprising:

a plurality of communications components each configured to;

receive a page message from a mobile switching center via a non-signaling link prior to establishing a signaling link with the mobile switching center, the page message configured to instruct the communications component to attempt to locate a mobile station, and

identify and release the mobile station based on a release message when another one of the communications components locates the mobile station, the release message configured to instruct the each communications component to stop attempting to locate the mobile station when no traffic channel exists between the communications component and the mobile station,

wherein the release message format is compatible with a plurality of protocols and comprises at least one cause code that specifies the reason for the release of the mobile station to be released.

2. The system of claim 1, wherein the communications component comprises one of a base station and an access network.

3. The system of claim 2, wherein the release message includes identifier information identifying the mobile station that is to be released.

4. The system of claim 3, wherein the mobile switching center is configured to transmit the release message via the non-signaling link when a signaling link between the mobile switching center and one of the base station and access network has not yet been established.

5. The system of claim 1, wherein the communications component comprises a base station, the base station configured to receive the release message from the mobile switching center in the absence of a dedicated signaling link between the mobile switching center and the base station, and the release message conforms to a message protocol specified in Telecommunications Industry Association standard TIA-2001-C.

6. The system of claim 5, wherein the release message comprises:

a header section comprising a message type code;

a mobile identity section comprising information identifying the mobile station to which the release message relates, and an identity code specifying which of an electronic serial number protocol and an international mobile serial identifier protocol is used to identify the mobile station; and

a cause section comprising information specifying the reason the mobile switching center is instructing the base station to stop attempting to locate the mobile station.

7. The system of claim 6, wherein the mobile identity section comprises an electronic serial number information sub-section when the identity code specifies that the electronic serial number protocol is used to identify the mobile station, and wherein the mobile identity section comprises an international mobile serial identifier information sub-section when the identity code specifies that the international mobile serial identifier protocol is used to identify the mobile station.

8. A method, comprising:

receiving, by each of a plurality of communications components, a page message from a mobile switching center via a non-signaling link prior to establishing a signaling link with the mobile switching center, the page message configured to instruct the communications component to attempt to locate a mobile station;

generating a release message for at least one of the communications components when another one of the communications components locates the mobile station, the release message configured to instruct the each communications component to stop attempting to locate the mobile station when no traffic channel exists between the communications component and the mobile station, the release message comprising information from which the mobile station is identified and at least one cause code that specifies the reason for stopping the attempt to locate the mobile station, the release message generated in a format that is compatible with a plurality of protocols; and

sending the release message, via a non-signaling link communication, to the communications component before a signaling link is established between the communications component and the mobile switching station.

9. The method of claim 8, wherein the communications component comprises one of a base station and an access network.

10. The method of claim 8, wherein the release message conforms to a message protocol specified in Telecommunications Industry Association standard TIA-2001-C.

11. The method of claim 8, wherein sending the release message further comprises sending the release message to the communications component in response to determining that the signaling link between the communications component and the mobile switching center has not yet been established.

12. The method of claim 8, wherein the communication component comprises a base station, the method further comprising:

establishing, by the base station, a traffic channel with the mobile station, and

before the base station establishes a signaling link with the mobile switching center, sending, from the mobile station, the release message to the base station via the non-signaling link to instruct the base station to stop attempting to locate the mobile station.

13. The method of claim 8, wherein the method further comprises:

communicating with the another communication component over a new signaling link in response to the another communication component locating the mobile station and establishing the new signaling link; and

absent a signaling link with the each communication component, sending the release message to the each communication component to instruct the each communication component discontinuing attempts to locate the mobile station.

14. The method of claim 8, wherein the communications component comprises an access network in data communication with the mobile station, the method further comprising sending the release message to the access network to instruct the access network to cease data communication with the mobile station upon determining that the access network is continuing to attempt data communications with the mobile station after the mobile station has ceased to accept data from the access network.

15. A mobile switching center, comprising:

an interface for communicating with a plurality of communications components, wherein the mobile switching center is configured to;

transmit to each communications component, a page message that is configured to attempt to locate a mobile station,

establish a traffic channel with one of the communications components that locates the mobile station,

generate a release message for each of the other communications components that is configured to instruct the communications component stop attempting to locate the mobile station, via the page message, when no traffic channel exists between the communications component and the mobile station, the release message comprising information from which the mobile station is identified and at least one cause code that specifies the reason for the release of the mobile station to be released, the release message generated in a format that is compatible with a plurality of protocols, and

transmit the release message, via a non-signaling link communication, to each of the other communications components before a signaling link is established between the communications component and the mobile switching station.

16. The mobile switching center of claim 15, wherein the communications component comprises one of a base station and an access network.

17. The mobile switching center of claim 15, wherein the mobile switching center is configured to send the release message to the communications component in the absence of a dedicated signaling link between the mobile switching center and the communications component.

18. The mobile switching center of claim 17, wherein the release message conforms to a message protocol specified in Telecommunications Industry Association standard TIA-2001-C.

19. The mobile switching center of claim 18, wherein the information from which the mobile station is identified is a mobile identity section that includes at least one of an identity code specifying which of an electronic serial number protocol and an international mobile serial identifier protocol identifying the mobile station.

20. The mobile switching center of claim 15, wherein the cause code specifies a scenario under which the release message is sent.
