1. A radio device, comprising:
- positioning modules, each facilitating one of multiple positioning techniques supported by said radio device, said positioning techniques including a broadcast positioning technique using broadcast radio signals, each broadcast from a respective one of a plurality of broadcast radio stations;
a selection parameter defined to enable selection of at least one selected one of said positioning techniques;
a receiver operable to receive a plurality of radio signals for each of said positioning techniques, said radio signals including said broadcast radio signals; and
processing circuitry coupled to said receiver and operable to select at least one selected one of said positioning techniques based on availability of said positioning techniques and said selection parameter and to calculate a location of said radio device using said received radio signals and said at least one selected one of said positioning techniques.

Abstract
A radio device that is capable of positioning itself using one or more available positioning techniques includes a selection parameter defined to enable selection of at least one of the available positioning techniques supported by the radio device for use in calculating the location of the radio device. At least one of the positioning techniques supported by the radio device is a broadcast positioning technique that uses broadcast radio signals broadcast from radio stations to calculate the location of the radio device.

14. A method for positioning a radio device using available positioning techniques, comprising the steps of:
-
providing a radio device supporting multiple positioning techniques including a broadcast positioning technique using broadcast radio signals, each broadcast from a respective one of a plurality of broadcast radio stations; establishing a selection parameter for selecting at least one selected one of said positioning techniques; receiving a plurality of radio signals for each of said positioning techniques, said radio signals including said broadcast radio signals; determining the availability of each of said positioning techniques to identify available positioning techniques; selecting at least one selected one of said available positioning techniques based on said selection parameter; and calculating a location of said radio device using said received radio signals and said at least one selected one of said available positioning techniques. - View Dependent Claims (15, 16, 17, 18, 19, 20)
