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.

Claims

1. A method to process wireless signal components for a mobile wireless access broadband service, comprising:

invoking a tune-away component to determine an alternative wireless communications path from at least one of inter-frequency and inter-RAT (radio access technology) communication paths;

receiving a BLOB (binary large object) message from an access node;

wherein the BLOB message facilitates monitoring a page from a disparate radio access technology (RAT) in a mobile broadband wireless access system;

wherein the BLOB message comprises a technology type field indicating the type of the disparate radio access technology;

configuring one or more tune-away parameters associated with a tune-away schedule utilized, the one or more tune-away parameters including at least a start frame number identifying a frame in which a first tune-away occurred and a start frame offset indicating a time duration between a beginning of the start frame and the first-tune away; and

selecting the alternative wireless communications path based at least in part on the tune-away component and at least one of the one or more tune-away parameters.

2. The method of claim 1, wherein a protocol is employed with at least one of an inter-frequency protocol, an inter-radio access technology protocol, or a hybrid communications protocol.

3. The method of claim 1, further comprising providing a parameter for initiating a signal strength measurement.

4. The method of claim 1, wherein a protocol includes at least one of a tune-away attribute or a tune-away control message.

5. An apparatus to process wireless signal components for a mobile wireless access broadband service, comprising:

means for invoking a tune-away component to determine an alternative wireless communications path from at least one of inter-frequency and inter-RAT (radio access technology) communication paths;

means for receiving a BLOB (binary large object) message from an access node;

wherein the BLOB message facilitates monitoring a page from a disparate radio access technology (RAT) in a mobile broadband wireless access;

wherein the BLOB message facilitates monitoring a page from a disparate radio access technology (RAT) in a mobile broadband wireless access;

means for configuring one or more tune-away parameters associated with a tune-away schedule utilized, the one or more tune-away parameters including at least a start frame number identifying a frame in which a first tune-away occurred and a start frame offset indicating a time duration between a beginning of the start frame and the first-tune away; and

means for selecting the alternative wireless communications path based at least in part on the tune-away component and at least one of the one or more tune-away parameters.

6. The apparatus of claim 5, wherein a protocol is employed with at least one of an inter-frequency protocol, an inter-radio access technology protocol, or a hybrid communications protocol.

7. The apparatus of claim 5, further comprising providing a parameter for initiating a signal strength measurement.

8. The apparatus of claim 5, wherein a protocol includes at least one of a tune-away attribute or a tune-away control message.

9. A non-transitory computer-readable medium having stored thereon computer-executable code, the computer-executable code comprising:

code for invoking a tune-away component to determine an alternative wireless communications path from at least one of inter-frequency and inter-RAT (radio access technology) communication paths;

code for receiving a BLOB (binary large object) message from an access node;

wherein the BLOB message facilitates monitoring a page from a disparate radio access technology (RAT) in a mobile broadband wireless access system;

wherein the BLOB message comprises a technology type field indicating the type of the disparate radio access technology;

code for configuring one or more tune-away parameters associated with a tune-away schedule utilized, the one or more tune-away parameters including at least a start frame number identifying a frame in which a first tune-away occurred and a start frame offset indicating a time duration between a beginning of the start frame and the first-tune away; and

code for selecting the alternative wireless communications path based at least in part on the tune-away component and at least one of the one or more tune-away parameters.

10. The non-transitory computer-readable medium of claim 9, wherein a protocol is employed with at least one of an inter-frequency protocol, an inter-radio access technology protocol, or a hybrid communications protocol.

11. The non-transitory computer-readable medium of claim 9, further comprising providing a parameter for initiating a signal strength measurement.

12. The non-transitory computer-readable medium of claim 9, wherein a protocol includes at least one of a tune-away attribute or a tune-away control message.

13. An apparatus configured to process wireless signal components for a mobile wireless access broadband service, comprising:

a processor configured to;

invoke a tune-away component to determine an alternative wireless communications path from at least one of inter-frequency and inter-RAT (radio access technology) communication paths;

receive a BLOB (binary large object) message from an access node;

wherein the BLOB message facilitates monitoring a page from a disparate radio access technology (RAT) in a mobile broadband wireless access system;

wherein the BLOB message comprises a technology type field indicating the type of the disparate radio access technology;

configure one or more tune-away parameters associated with a tune-away schedule utilized, the one or more tune-away parameters including at least a start frame number identifying a frame in which a first tune-away occurred and a start frame offset indicating a time duration between a beginning of the start frame and the first-tune away; and

select the alternative wireless communications path based at least in part on the tune-away component and at least one of the one or more tune-away parameters; and

a memory coupled to the processor for storing data.
