1. A method to process wireless signal components for a mobile wireless access broadband service, comprising:
- defining a protocol that controls whether to invoke a tune away component to determine an alternative wireless communications path;
defining one or more tune away parameters for the protocol; and
selecting the alternative wireless communications path based in part on the tune away component and at least one of the tune away parameters.

Abstract
Systems and methods are provided for processing wireless signal components for a mobile wireless access broadband service. This can include processes for defining a protocol that controls whether to invoke a tune away component to determine an alternative wireless communications path. This can include defining one or more tune away parameters for the tune away component. The process can then automatically select the alternative wireless communications path based in part on the tune away procedure and at least one of the tune away parameters.

12. A method for detecting pages in a mobile broadband wireless access system, comprising:
-
enabling a tune-away protocol to determine if a page has been received in a communications system, the tune-away protocol specifies timing differences between components in the communications system; and
sampling for the page in accordance scheduled intervals specified with the tune-away protocol. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
