1. A method comprising:
- determining the direction of movement of a wireless communication device;
receiving more than one location area codes from a mobile communication network;
retrieving position data associated with each of the one or more location area codes;
selecting one of the location area codes to be used in determining the default position of the wireless communication device on the basis of the direction of movement of the wireless communication device;
determining a position of the wireless communication device utilizing the position data associated with the selected location area code as the default position of the wireless communication device, where only a portion of a global cell identity is received by the wireless communication device, andtransmitting the determined position of the wireless communication device and the selected location area code to the mobile communication network.

Abstract
A method for positioning a wireless communication device includes storing position data relating to one or a plurality of reference areas to at least one data base. It is examined which of said reference areas is located in the vicinity of the wireless communication device, and at least position data about the reference area located in the vicinity of the wireless communication device is retrieved for the wireless communication device. In order to perform the positioning, the method further includes selecting the reference area located in the vicinity of the wireless communication device as the default position of the wireless communication device.
