Method of acquiring a mobile station identifier in a hybrid network
An access network obtains a non-native mobile station identifier, such as an International Mobile Station Identifier, for use in establishing a packet data call by inducing the mobile station to transmit a non-native message containing the mobile station identifier encapsulated in a native message. The access network de-capsulates and parses the non-native message to obtain the mobile station identifier.
1. A method of obtaining a non-native mobile station identifier used by a mobile station for signaling over an air interface in a non-native network, the method comprising:
inducing the mobile station to transmit a non-native message containing a mobile station identifier encapsulated in an native message;
de-capsulating and parsing the non-native message to obtain the mobile station identifier.
2. The method of claim 1 wherein inducing the mobile station to transmit a non-native message containing a mobile station identifier encapsulated in an native message comprises sending a non-native message to said mobile station encapsulated in a native message to induce the mobile station to transmit a responsive non-native message containing the mobile station identifier.
3. The method of claim 2 wherein the non-native message transmitted to the mobile station is a status request message.
4. The method of claim 3 wherein the non-native transmitted by the mobile station comprises an extended status response message.
5. The method of claim 1 wherein the non-native message is a cdma2000 1× signaling message.
6. The method of claim 5 wherein the native message is an HRPD message.
7. The method of claim 1 wherein the non-native mobile station identifier comprises an International Mobile Station Identifier.
8. An access network including a controller configured to:
induce a mobile station to transmit a non-native message to the base station containing a non-native mobile station identifier encapsulated in an native message;
de-capsulate the non-native message; and
parse the non-native message to obtain a non-native mobile station identifier.
9. The access network of claim 8 wherein the controller induces the mobile station to send a non-native message containing the non-native mobile station identifier by sending the mobile station a second non-native message encapsulated in a second native message.
10. The access network of claim 9 wherein the non-native message transmitted to the mobile station is a status request message.
11. The access network of claim 10 wherein the non-native transmitted by the mobile station comprises an extended status response message.
12. The access network of claim 9 wherein the non-native message is a cdma2000 1×signaling message.
13. The access network of claim 12 wherein the native message is an HRPD message.
14. The access network of claim 8 wherein the non-native mobile station identifier is an International Mobile Station Identifier.
