1. A method for detecting pages in a mobile broadband wireless access system, comprising:
- exchanging a BLOB (binary large object) between an access terminal and an access node to facilitate monitoring a page from at least one disparate radio access technology (RAT), the BLOB comprising at least a Message ID field and a Technology Type field indicating the type of the disparate radio access technology;
enabling a tune-away protocol to determine whether a page has been received from the at least one disparate radio access technology, the tune-away protocol specifying timing differences between components in the communications system; and
sampling for the page in accordance with scheduled intervals specified by the tune-away protocol.

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.

16. A wireless communications apparatus, comprising:
-
a memory that includes one or more protocol parameters for a tune-away timing schedule with respect to an access terminal, the one or more protocol parameters including at least a Super Frame Number identifying a super frame in which an initial tune away occurred and a Start Super Frame Offset indicating an elapsed time between the start of the identified super frame and the start of the initial tune away; and a processor that determines timing differences between the access terminal and an access network associated therewith, determines a timing correction parameter in view of the timing differences and the one or more protocol parameters, monitors pages from at least one disparate radio access technology (RAT) by using a BLOB (binary large object) message received from an access terminal or an access node, wherein the BLOB comprises at least a message ID field and a technology type field indicating the type of the disparate asynchronous radio access technology, and updates the timing Schedule with a parameter that accounts for timing differences between at least two different timing components corresponding to at least the access terminal and the at least one disparate RAT.

17. An apparatus for allocating base station resources during a tune-away, comprising:
-
means for determining a tune-away protocol timing schedule for an access terminal; means for adjusting at least one protocol parameter in view of the protocol schedule to compensate for a timing difference between the access terminal and an access network; means for monitoring pages from at least one disparate asynchronous radio access technology (RAT) using a time-away sequence controlled by the timing schedule and a BLOB (binary large object) message received from an access terminal or an access node, wherein the timing schedule is updated with a parameter to account for timing differences between the access terminal and the at least one disparate asynchronous radio access technology and the BLOB comprises at least a message ID field and a technology type field indicating the type of the disparate asynchronous radio access technology; and means for performing a handoff to an alternative communications channel on the disparate radio access technology based in part on the protocol parameter and the monitored pages.
