Method and system for radio-independent predictive handoffs in a wireless network
First Claim
1. A method for call handoff in a wireless network comprising a controller and a plurality of base stations including first and second base stations, the method comprising:
- determining at the first and second base stations at least one respective usability factor, each respective usability factor providing a relative measure of the desirability of receiving control of a mobile unit;
communicating each of the at least one usability factors from each of the first and second base stations to the controller, the controller located remote from the first and second base stations; and
selecting one of the first and second base stations to receive control of the mobile unit by comparing, by the controller, the at least one usability factor for the first base station to the at least one usability factor for the second base station.

Abstract
According to one embodiment of the invention, a method includes determining, at a base station, at least one usability factor providing a relative measure of the desirability of receiving control of a mobile unit. The method also includes communicating, from a base station to a remote controller, the determined at least one usability factor for comparison to at least one usability factor of another base station as determined at the other base station and communicated to the remote controller. The method also includes taking control, by the base station, of the mobile unit in response to receiving a signal from a controller to take control of the mobile unit in response to comparison of the controller of the at least one usability factor determined by the base station and the at least one usability factor determined by the other base station.

12. An apparatus comprising:
a wireless network base station, the base station operable to receive a wireless call and transmit at least portions of the call to a wired line, the base station further comprising logic encoded in a computer-readable medium that when executed on a processor is operable to;
determine at least one usability factor providing a relative measure of the desirability of receiving control of a mobile unit;
communicate the at least one usability factor to a remote controller for comparison to at least one usability factor of another base station that is determined at the other base station and communicated to the remote controller; and
receive a signal from the controller to take control of the mobile unit in response to comparison by the controller of the at least one usability factor determined by the base station and at least one usability factor to be determined by the other base station. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method implemented by a base station in a wireless network comprising:
-
determining, at the base station, at least one usability factor providing a relative measure of the desirability of receiving control of a mobile unit;
communicating, from the base station to a remote controller, the determined at least one usability factor for comparison to at least one usability factor of another base station that is determined at the other base station and communicated to the remote controller; and
taking control, by the base station, of the mobile unit in response to receiving a signal from the controller to take control of the mobile unit in response to comparison by the controller of the at least one usability factor determined by the base station and the at least one usability factor determined by the other base station. - View Dependent Claims (24, 25, 26)

27. An apparatus for use with a wireless network including a plurality of base stations, the apparatus comprising:
a controller operable to;
receive a first at least one usability factor from a first base station and a second at least one usability factor from a second base station, the first and second at least one usability factors each providing a relative measure of the desirability of receiving control of a mobile unit;
compare the first at least one usability factor to the second at least one usability factor; and
select the first or second base station to take control of the mobile unit based on the comparison. - View Dependent Claims (28, 29, 30, 31)

32. A method implemented by a controller in a wireless network comprising:
-
receiving, by the controller, a first at least one usability factor from a first base station and a second at least one usability factor from a second base station, the first and second at least one usability factors each providing a relative measure of the desirability of receiving control of a mobile unit;
comparing, by the controller, the first at least one usability factor to the second at least one usability factor; and
selecting, by the controller, the first or second base station to take control of the mobile unit based on the comparison. - View Dependent Claims (33, 34, 35, 36)

37. A wireless network comprising:
-
a plurality of base stations, the plurality including first and second base stations;
at least one controller;
means for determining at the first and second base stations at least one respective usability factor, each respective usability factor providing a relative measure of the desirability of receiving control of a mobile unit;
means for communicating each of the at least one usability factors from each of the first and second base stations to the controller, the controller located remote from the first and second base stations; and
means for selecting one of the first and second base stations to receive control of the mobile unit by comparing, by the controller, the at least one usability factor for the first base station to the at least one usability factor for the second base station. - View Dependent Claims (38, 39, 40)
