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, the tune-away component samples both inter-frequency and inter-RAT (radio access technology) communication paths as candidate alternate communication paths;
defining one or more tune-away parameters associated with a tune-away schedule utilized in connection with the protocol, the tune-away parameters including at least a Start Super Frame Number identifying a super frame in which a first tune-away occurred and a Start Super Frame Offset indicating a time duration between the beginning of the Start Super Frame and the first-tune away;
sending a BLOB (binary large object) message from an access terminal or an access node to facilitate monitoring a page from a disparate radio access technology (RAT) in a mobile broadband wireless access system, wherein the BLOB comprises at least a message ID field and a technology type field indicating the type of the disparate radio access technology; and
selecting the alternative wireless communications path based in part on the tune-away component and at least one of the tune-away parameters, and the page from the disparate RAT.

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.
