9. The method of claim 1, wherein the data of the RegistrationRadiusFlag comprises data selected from the group consisting of:

a data value indicating that registration is to be performed when the access terminal travels a distance more than a registration distance; and

a data value indicating that registration is to be performed when the access terminal moves to a sector with a different latitude and longitude.

2. A computer readable non-transitory medium comprising computer executable instructions that, in response to execution, cause a computing system to perform operations, at an access terminal to process an Open state command, the operations comprising:

receiving a Control Channel and the Forward Traffic Channel;
