GPS/WIFI INDOOR/OUTDOOR DETECTION
First Claim
1. A method for determining indoor or outdoor location of a portable communication device, the method comprising:
- measuring a signal strength of at least one of a location service signal, a radio access network (RAN) signal, and a small coverage area signal that is detectable within a current location of the portable communication device;
comparing the signal strength to a corresponding pre-established signal strength threshold;
obtaining contextual information by accessing sensor data from a first sensor selected based on a result of the comparing;
determining, utilizing the contextual information, whether the portable communication device is transitioning between an outdoor space and an indoor space;
configuring the portable communication device for an outdoor space in response to determining that the portable communication device is transitioning from the indoor space to the outdoor space; and
configuring the portable device for an indoor space in response to determining the portable device is transitioning from the outdoor space to the indoor space.

Abstract
A portable communication device and method provide for determining indoor or outdoor location of the device. The method includes measuring a signal strength of at least one of a location service signal, a RAN signal, and a small coverage area signal that is detectable within a current location of the portable communication device, comparing signal strength to corresponding pre-established signal strength threshold, and obtaining contextual information by accessing sensor data from at least one sensor selected based on a result of the comparing. The method also includes configuring the portable communication device for operation within an outdoor space in response to determining that the portable communication device is transitioning from the indoor space to the outdoor space and configuring the portable device for operation within an indoor space in response to determining the portable device is transitioning from the outdoor space to the indoor space.

12. A portable communication device, comprising:
-
at least one communication mechanism that enables communicating with at least one of a location service, a radio access network (RAN), and a small coverage area device; a first sensor that generates sensor data that can be utilized as contextual information that may differentiate between an inside location versus outside location of the portable communication device; at least one processor that is communicatively coupled to the at least one sensor and the at least one communication mechanism; and an indoor/outdoor detection utility that executes on the at least one processor and configures the portable communication device to; measure a signal strength of at least one of a location service signal, a RAN signal, and a small coverage area signal that is detectable within a current location of the portable communication device; compare the signal strength to a corresponding pre-established signal strength threshold; obtain contextual information by accessing sensor data from at least one sensor selected based on a result of the comparing; determine, utilizing the contextual information, whether the portable communication device is transitioning between an outdoor space and an indoor space; configure for an outdoor space when in response to determining that the portable communication device is transitioning from the indoor space to the outdoor space; and configuring the portable device for an indoor space in response to determining the portable device is transitioning from the outdoor space to the indoor space. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
