Abstract

Methods and systems are provided for implementing predictive personality negotiation during session negotiation. In an embodiment, an EV-DO access node negotiates a first session with an access terminal, which involves negotiating a comprehensive set of personalities with the access terminal for the first session. The access node then records a list of personalities actually used by the access terminal during the first session. That list is a subset of the comprehensive set. The access node then negotiates a second session with the access terminal, which involves negotiating only that subset of personalities with the access terminal for the second session.

Claims

1. A method comprising:

an access node negotiating a first session with a first access terminal, wherein negotiating the first session with the first access terminal comprises negotiating a comprehensive set of two or more personalities with the first access terminal for the first session;

the access node recording a first list of personalities actually used by the first access terminal for engaging in at least one packet flow during the first session, wherein the first list of personalities makes up a first subset of the comprehensive set of personalities, wherein the first subset consists of one or more but not all of the personalities in the comprehensive set; and

the access node negotiating a second session with the first access terminal, wherein negotiating the second session with the first access terminal comprises negotiating only the first subset of personalities with the first access terminal for the second session.

2. The method of claim 1, wherein the access node comprises an Evolution Data Optimized (EV-DO) access node, wherein the first access terminal comprises an EV-DO access terminal, wherein either or both of the access node and the first access terminal operate in compliance with (a) IS-856, Revision A or (b) both IS-856, Release 0 and IS-856, Revision A.

3. The method of claim 2, wherein the access node comprises a radio network controller (RNC) and at least one base transceiver station (BTS).

4. The method of claim 1, wherein the first access terminal comprises at least one of a cellular telephone, a personal digital assistant (PDA), a computer, a laptop computer, a laptop air card, and a hybrid access terminal.

5. The method of claim 1, wherein the comprehensive set of personalities consists of all personalities provided by the access node.

6. The method of claim 5, wherein the comprehensive set of personalities comprises (a) at least one personality associated with IS-856, Release 0 and (b) at least one personality associated with IS-856, Revision A.

7. The method of claim 1, wherein the comprehensive set of personalities consists of five personalities.

8. The method of claim 7, wherein the comprehensive set of personalities consists of (a) two personalities associated with IS-856, Release 0 and (b) three personalities associated with IS-856, Revision A.

9. The method of claim 1, further comprising using the same numbering convention of the personalities in the comprehensive set across at least two access-node vendors and/or across at least two radio-network-controller-(RNC) vendors.

10. An Evolution Data Optimized (EV-DO) access node comprising:

an wireless-communication interface for providing an EV-DO coverage area;

a processor; and

data storage comprising instructions executable by the processor for;

negotiating a first session with a first access terminal, wherein negotiating the first session with the first access terminal comprises negotiating a comprehensive set of two or more personalities with the first access terminal for the first session;

recording a first list of personalities actually used by the first access terminal for engaging in at least one packet flow during the first session, wherein the first list of personalities makes up a first subset of the comprehensive set of personalities, wherein the first subset consists of one or more but not all of the personalities in the comprehensive set; and

negotiating a second session with the first access terminal, wherein negotiating the second session with the first access terminal comprises negotiating only the first subset of personalities with the first access terminal for the second session.

11. The access node of claim 10, wherein the access node comprises a radio network controller (RNC) and at least one base transceiver station (BTS).

12. The access node of claim 10, wherein the comprehensive set of personalities consists of all personalities provided by the access node.

13. The access node of claim 12, wherein the comprehensive set of personalities comprises (a) at least one personality associated with IS-856, Release 0 and (b) at least one personality associated with IS-856, Revision A.

14. The access node of claim 10, wherein the comprehensive set of personalities consists of (a) two personalities associated with IS-856, Release 0 and (b) three personalities associated with IS-856, Revision A.

15. A method comprising:

an access node negotiating a first session with an access terminal, wherein negotiating the first session with the access terminal comprises negotiating a first set of two or more personalities with the access terminal for the first session;

the access node recording a list of personalities actually used by the access terminal for engaging in at least one packet flow since negotiating the first session with the access terminal, wherein the list of personalities makes up a subset of the first set of personalities, wherein the subset consists of one or more but not all of the personalities in the first set; and

the access node negotiating a second session with the access terminal, wherein negotiating the second session with the access terminal comprises negotiating only the subset of personalities with the access terminal for the second session.
