Abstract
Method, and associated apparatus, for operating a hybrid access terminal operable in a CDMA 1x/EVDO hybrid communication session system. The hybrid access terminal is operable to communicate pursuant to an EVDO communication session and to a PPP communication session. The opening and closing of the communication sessions are independent of one another. Opening of one session does not require opening of another of the sessions. And, closing of one of the sessions does not require closing of the other of the sessions.
Claims20
A method for operating a hybrid access terminal capable of having an EVDO (Evolution Data Only) session and capable of having a PPP (Point to Point Protocol) session, said method comprising:
- opening at least one of the EVDO session and the PPP session when a radio of the hybrid access terminal is in an on state;
- closing all of the at least one of the EVDO session and the PPP session opened during said opening if the radio of the hybrid terminal is turned-off;
- and
- selectively closing any of the at least one of the EVDO session and the PPP session opened during said opening if the radio of the hybrid access terminal otherwise remains in the on state.
A hybrid access terminal capable of having an EVDO (Evolution Data Only) session and capable of having a PPP (Point to Point Protocol) session, said hybrid access terminal comprising a mechanism configured:
- to open at least one of the EVDO session and the PPP session when a radio of the hybrid access terminal is in an on state;
- to close all of the at least one of the EVDO session and the PPP session if the radio of the hybrid access terminal is turned-off;
- and
- to selectively close any of the at least one of the EVDO session and the PPP session if the radio of the hybrid access terminal is in the on state.
A method for operating an always-on hybrid access terminal, said method comprising:
- turning-on a radio of the hybrid access terminal;
- opening an EVDO session and a PPP session if an application that uses packet data services is running;
- turning-off the radio of the hybrid access terminal;
- and
- selectively closing at least one of the EVDO session and the PPP session, selection to close one of the EVDO session and the PPP session untied to selection to close the other of the EVDO session and the PPP session.
