A method for determining a position of a portable electronic device is useful for conserving power, processor and bandwidth resources. The method includes detecting at a portable electronic device a first signal received from a local terminal (step 605). In response to the first signal, a second signal is transmitted from the device, indicating a proximity of the portable electronic device to the local terminal (step 610). Positioning method priority information, which is based on a location of the local terminal and is received from the local terminal in response to the second signal, is then processed at the device (step 615). A positioning method priority list based on the positioning method priority information is then processed (step 620). Finally, the position of the portable electronic device is determined using a positioning method identified in the positioning method priority list (step 625).
