Method, device and system to show heading in a cellular network
First Claim
1. A method for defining the direction to a desired location in a cellular network in which base stations transfer communication and form cells, and in which base stations hold connections within the cell to portable transceivers (1) provided with a display (7) and equipped with a detector (5) that indicates the direction of the earth'"'"'s magnetic field (10), and with the said method defining the transceivers location within the cellular network area characterized in that the direction to a desired location being calculated as a network service on the basis of the transceiver'"'"'s defined location in relation to the direction of the earth'"'"'s magnetic field, and this direction being sent as a message from the base station to the transceiver that, taking account of the transceiver'"'"'s direction in relation to the direction of the earth'"'"'s magnetic field and the directional information contained in the sent message, shows the direction to the desired location on the display.

Abstract
This invention relates to a method, a device and a system for indicating the direction to the desired point in a cellular network in which base stations transfer communication and form cells, and in which base stations communicate with the mobile transceivers within the cell area. According to the method the direction to a desired location is calculated as a network service on the basis of the transceiver'"'"'s (1) defined location in relation to the direction of the earth'"'"'s magnetic field, and this direction being sent as a message from the base station to the transceiver that is equipped with a detector (5) that indicates the direction of the earth'"'"'s magnetic field. According to the invention based on the directional information contained in the sent message and the direction of the transceiver the direction to the desired location is shown on the display (7) of the transceiver. In the device according to the invention the transceiver (1) is equipped with a detector (5) detecting the direction of the earth'"'"'s magnetic field and with a data processing unit (6) for processing directional information and for showing the direction (8) on a display (7). The system according to the invention consists of those functions by which the directional information by request is delivered to the customer. With the aid of this invention resting on the operation of a cellular network the direction to a desired point can be shown user-friendly while the direction of the earth'"'"'s magnetic field is used as the reference direction.
