1. A method for allowing a terminal to use a previously established session of a packet data transmission standard designated by an identifier, the method comprising:requesting establishment of a communication via a second access network between the terminal and a network access server to use the se
1. A method for allowing a terminal to use a previously established session of a packet data transmission standard designated by an identifier, the method comprising:requesting establishment of a communication via a second access network between the terminal and a network access server to use the session designated by the identifier, the session being previously established via a first access network between the terminal and the network access server, wherein the first and second access networks use different multiple access modulation techniques;requesting the terminal to provide a session key previously established between the terminal and the network access server; andestablishing the communication via the second access network if the terminal provides the previously established session key.2. The method of claim 1, wherein the first access network is a radio access network.3. The method of claim 1, wherein the second access network is a radio access network.4. The method of claim 1, wherein the packet data transmission standard comprises a point-to-point protocol.5. The method of claim 1, wherein the network access server comprises a packet data service node.6. A method for allowing a terminal to use a same session of a standard for packet data transmission when the terminal changes from a first access network to a second access network, the method comprising:establishing a communication between a network access server and the terminal via the first access network using the session of the standard for packet data transmission, wherein the session is designated by an identifier;establishing a security association between the terminal and the network access server;receiving a request to establish a communication between the network access server and the terminal via the second access network using the session designated by the identifier, the first and second access networks using different multiple access modulation techniques; andestablishing the communication with the terminal via the second access network if the network access server verifies the security association between the terminal and the network access server.7. The method of claim 6, wherein the first access network is a radio access network.8. The method of claim 6, wherein the second access network is a radio access network.9. The method of claim 6, wherein the standard for packet data transmission comprises a point-to-point protocol.10. The method of claim 6, wherein the network access server comprises a packet data service node.11. The method of claim 6, wherein the security association comprises a session key.12. An apparatus allowing a terminal to use a previously established session of a packet data transmission standard designated by an identifier, the apparatus comprising:a processor; anda processor-readable storage medium accessible by the processor and containing a set of instructions executable by the processor to:request establishment of a communication via a second access network between the terminal and a network access server to use the session designated by the identifier, the session being previously established via a first access network between the terminal and the network access server, wherein the first and second access networks use different multiple access modulation techniques;request the terminal to provide a session key previously established between the terminal and the network access server; andestablish the communication via the second access network if the terminal provides the previously established session key.13. The apparatus of claim 12, wherein the first access network is a radio access network.14. The apparatus of claim 12, wherein the second access network is a radio access network.15. The apparatus of claim 12, wherein the packet data transmission standard comprises a point-to-point protocol.16. The apparatus of claim 12, wherein the network access server comprises a packet data service node.17. An apparatus for allowing a terminal to use a same session of a standard for packet data transmission when the terminal changes from a first access network to a second access network, the apparatus comprising:a processor; anda processor-readable storage medium accessible by the processor and containing a set of instructions executable by the processor to:establish a communication between a network access server and the terminal via the first access network using the session of the standard for packet data transmission, wherein the session is designated by an identifier;establish a security association between the terminal and the network access server;receive a request to establish a communication between the network access server and the terminal via the second access network using the session designated by the identifier, the first and second access networks using different multiple access modulation techniques; andestablish the communication with the terminal via the second access network if the network access server verifies the security association between the terminal and the network access server.18. The apparatus of claim 17, wherein the first access network is a radio access network.19. The apparatus of claim 17, wherein the second access network is a radio access network.20. The apparatus of claim 17, wherein the standard for packet data transmission comprises a point-to-point protocol.21. The apparatus of claim 17, wherein the network access server comprises a packet data service node.22. The apparatus of claim 17, wherein the security association comprises a session key.23. The method of claim 6, wherein the first access network comprises at least one of a high data rate (HDR) system, an Industry Standard 2000 (IS-2000) system, a time division multiple access (TDMA) system, a wideband code division multiple access (W-CDMA) system, and an EDGE system.24. The method of claim 6, wherein the second access network comprises at least one of a high data rate (HDR) system, an Industry Standard 2000 (IS-2000) system, a time division multiple access (TDMA) system, a wideband code division multiple access (W-CDMA) system, and an EDGE system.25. The method of claim 1, wherein the identifier comprises an identifier of the terminal.26. The method of claim 1, wherein the terminal comprises a mobile phone.27. The method of claim 1, wherein the terminal comprises a stationary device.28. The method of claim 1, further comprising establishing an interface between the network access server and the first access network.
