Active-set management based on an associated codec
First Claim
1. A method comprising:
- a radio access network (RAN) determining a comparative signal-strength measure based on a comparison of a signal-strength measurement for a candidate sector to a signal-strength measurement for at least one active sector in an active set of a wireless communication device (WCD);
determining, by the RAN, whether or not the comparative signal-strength measure is less than a first threshold;
if the comparative signal-strength measure is less than a first threshold, then the RAN;
determining a comparative codec-quality measure based on a comparison of a first codec associated with the candidate sector to a second codec associated with the active sector;
determining whether or not the comparative codec-quality measure is greater than a second threshold; and
if the comparative codec-quality measure is greater than a second threshold, then sending a message to the WCD that indicates to add the candidate sector to the active set; and
otherwise, refraining from adding the candidate sector to the active set.

Abstract
Embodiments may be implemented to take codec quality into account when helping to manage the active set of a wireless communication device (WCD). An illustrative method may involves a radio access network (RAN) component determining a comparative signal-strength measure for a candidate sector as compared to at least one active sector in the active set of a WCD, determining a comparative codec-quality measure for the candidate sector as compared to the at least one active sector in the active set of a WCD, and based at least in part on both (a) the comparative signal-strength measure and (b) the comparative codec-quality measure, making a determination as to whether or not to add the candidate sector to the active set.

12. A method comprising:
-
a radio access network (RAN) determining a comparative signal-strength measure based on a comparison of a signal-strength measurement for a candidate sector to a signal-strength measurement for at least one active sector in an active set of a wireless communication device (WCD); determining, by the RAN, a comparative codec-quality measure based on a comparison of a first codec associated with the candidate sector to a second codec associated with the active sector; based at least in part on both (a) the comparative signal-strength measure and (b) the comparative codec-quality measure, the RAN making a determination as to whether or not to add the candidate sector to the active set; if the determination is to add the candidate sector to the active set, then sending a message from the RAN to the WCD that indicates to add the candidate sector to the active set; and otherwise, refraining from adding the candidate sector to the active set.

16. A radio access network (RAN) component comprising:
-
a non-transitory computer-readable medium; and program instructions stored on the computer-readable medium and executable by at least one processor to; determine a comparative signal-strength measure based on a comparison of a signal-strength measurement for a candidate sector to a signal-strength measurement for at least one active sector in an active set of a wireless communication device (WCD); determine a comparative codec-quality measure based on a comparison of a first codec associated with the candidate sector to a second codec associated with the active sector; based at least in part on both (a) the comparative signal-strength measure and (b) the comparative codec-quality measure, determine whether or not to add the candidate sector to the active set; if the determination is to add the candidate sector to the active set, then send a message to the WCD that indicates to add the candidate sector to the active set; and if the determination is to not add the candidate sector to the active set, then refrain from adding the candidate sector to the active set. - View Dependent Claims (17, 18, 19, 20)
