Abstract
Methods, apparatus, and computer program products for determining a position of a mobile device in a network service area are described. An example of a method for determining the position of the mobile device includes receiving a positioning request for the position of the mobile device and, in response to receiving the positioning request, receiving signal characteristic measurements, estimating an a priori mobile device position area based on the signal characteristic measurements, determining a selected AD model, and determining the position of the mobile device using the selected AD model.

A method of determining a position of a mobile device in a network service area, the method comprising:
- receiving a first positioning request for the position of the mobile device;
- and
- in response to receiving the first positioning request,
- receiving first signal characteristic measurements;
- estimating a first a priori mobile device position area based on the first signal characteristic measurements;
- determining a selected assistance data (AD) model;
- and
- determining the position of the mobile device using the selected AD model.
A method of determining a position of a mobile device in a network service area, the method comprising:
- sending a first positioning request;
- and
- in response to the first positioning request, receiving first position information based on the position of the mobile device determined by:
- receiving first signal characteristic measurements;
- estimating a first a priori mobile device position area based on the first signal characteristic measurements;
- determining a selected assistance data (AD) model;
- and
- determining the position of the mobile device using the selected AD model.

- one or more processors configured to receive a first positioning request for the position of the mobile device;
- and
- the one or more processors configured to, in response to receiving the first positioning request,
- receive first signal characteristic measurements;
- estimate a first a priori mobile device position area based on the first signal characteristic measurements;
- determine a selected assistance data (AD) model;
- and
- determine the position of the mobile device using the selected AD model.
An apparatus for determining a position of a mobile device in a network service area, the apparatus comprising a transceiver configured to:
- send a first positioning request;
