Abstract

Techniques are described that can be used to assign identifiers to mobile stations in a Network Access Provider (NAP) domain and a paging identifier. In some cases, the NAP identifier and paging identifier can be unique in the NAP domain and the paging group domain. The paging identifier can be derived from a NAP identifier.

Claims

1. A method comprising:

receiving a Network Access Provider (NAP) domain identifier and

determining a paging identifier of a mobile station, the paging identifier being either independent of the NAP domain identifier or based on the NAP domain identifier.

2. The method of claim 1, further comprising:

transmitting one of a NAP domain identifier or a paging identifier to a network;

receiving a second NAP domain identifier; and

determining a paging mobile station identifier based on the second NAP domain identifier.

3. The method of claim 2, wherein the transmitting one of a NAP domain identifier or a paging identifier to a network do not expose a media access control (MAC) address of the mobile station.

4. The method of claim 1, wherein the determining a paging identifier comprises determining the paging identifier as a function of at least one of the NAP domain identifier, Access Service Network ID, Paging Controller ID, and serving base station ID.

5. The method of claim 1, further comprising:

receiving a paging group identifier from a network;

determining whether the paging group identifier matches a paging group identifier of the mobile station;

in response to the paging group identifier not matching a current paging group identifier of the mobile station, transmitting the NAP domain identifier to the network; and

receiving a paging mobile station identifier that is valid in the current paging group.

6. The method of claim 1, wherein the receiving a NAP domain identifier takes place in response to one of network re-entry from uncontrolled hand over, network re-entry after idle mode, and network re-entry from Deregistration with Content Retention.

7. A method comprising:

determining a unique Network Access Provider (NAP) domain identifier of a mobile station;

determining a paging identifier for the mobile station based on the NAP domain identifier;

determining another NAP domain identifier that is unique in the NAP domain of the mobile station in response to the paging identifier not being unique in the paging domain of the mobile station; and

transmitting a unique NAP domain identifier to a paging controller.

8. The method of claim 7, wherein the determining a paging identifier for the mobile station based on the NAP domain identifier comprises determining a paging identifier using one of:

a hash, concatenation operation, and derivation operation that approximately uniformly maps a paging identifiers onto a paging identifier space.

9. The method of claim 7, further comprising:

transmitting an ASN-gateway IP address to the mobile station;

receiving the ASN-gateway IP address from the mobile station;

receiving a NAP identifier from the mobile station; and

based on the received ASN-gateway IP address and NAP identifier, providing context associated with the mobile station to an ASN-gateway associated with a next NAP domain of the mobile station and to a serving base station for the mobile station.

10. The method of claim 9, further comprising:

identifying a serving ASN-gateway based on the received ASN-gateway IP address and

transferring the context from the serving ASN-gateway to a next serving ASN-gateway.

11. The method of claim 7, further comprising:

independent of a request from the mobile station, updating the NAP domain identifier for the mobile station.

12. A computer-readable medium comprising instructions stored thereon, which when executed by a computer cause the computer to:

accept a Network Access Provider (NAP) domain identifier;

request to store the NAP domain identifier;

determine a paging identifier of a mobile station, the paging identifier based on the NAP domain identifier;

request to store the paging identifier; and

request to transmit the NAP domain identifier in connection with a communication with a network.

13. The computer-readable medium of claim 12, wherein instructions to determine the paging identifier comprise instructions to determine the paging identifier as a function of at least one of the NAP domain identifier, an Access Service Network ID, a Paging Controller ID, and a serving base station ID.

14. The computer-readable medium of claim 12, further comprising instructions stored thereon, which when executed by a computer cause the computer to:

determine whether a received paging group identifier matches a paging group identifier of the mobile station;

in response to the paging group identifier not matching a current paging group identifier of the mobile station, transmit the NAP domain identifier to the network; and

receive a paging mobile station identifier that is valid in the current paging group.

15. The computer-readable medium of claim 12, wherein the request to transmit the NAP domain identifier occurs in connection with a periodic check-in with the network or a return to connected mode.

16. A system comprising:

one or more antennae;

a wireless network interface communicatively coupled to the one or more antennae;

a memory; and

a processor configured to;

accept a Network Access Provider (NAP) domain identifier,

request to store the NAP domain identifier in the memory,

determine a paging identifier of a mobile station, the paging identifier based on the NAP domain identifier,

request to store the paging identifier in the memory, and

request to transmit the NAP domain identifier in connection with a communication with a network.

17. The system of claim 16, wherein to request to transmit the NAP domain identifier occurs in connection with a periodic check-in with the network or a return to connected mode.

18. The system of claim 16, wherein to determine the paging identifier, the processor is to determine the paging identifier as a function of at least one of the NAP domain identifier, an Access Service Network ID, a Paging Controller ID, and a serving base station ID.

19. The system of claim 16, wherein the processor is to:

determine whether a received paging group identifier matches a paging group identifier of the mobile station;

in response to the paging group identifier not matching a current paging group identifier of the mobile station, request to transmit the NAP identifier to the network; and

receive a paging mobile station identifier that is valid in the current paging group.

20. The system of claim 16, wherein the request to transmit the NAP domain identifier occurs in connection with a periodic check-in with the network or a return to connected mode.
