Benefits of technology

"The invention is a method and system for detecting movement of a mobile device in a radio system and using that information to improve movement estimation and adjust the operation of the radio system. This can reduce power consumption, increase network capacity, and improve data transmission quality."

Problems solved by technology

Consequently, the loading of base stations and the interference level are high and channel changes as great as possible.
This wastes resources and power, and increases the interference level because several measuring and signalling operations are performed all too often with respect to what the real movement of the terminal requires.

Embodiment Construction

[0013]The solution of the invention is applicable to a mobile transceiver of a radio system, in particular.

[0014]First the radio system will be described by means of FIG. 1. A typical digital radio system comprises a base station 1, mobile transceiver units 2 to 4 and a base station controller 5. The base station 1 communicates with mobile transceiver units 2 to 4 using signals 6 to 8. The base station 1 is connected to the base station controller 5 by a digital transmission link 9. The mobile transceiver units 2 to 4 are terminals, e.g. mobile stations. The signals 6 to 8 between the base station 1 and the mobile transceivers 2 to 4 include digitised information which is e.g. speech or data information produced by subscribers or control information produced by the radio system.

[0015]FIG. 2 is a block diagram illustrating a mobile transceiver. The transceiver comprises an antenna 100 for transmission and reception. When a signal is received, it propagates from the antenna 100 to a d...

Abstract

A mobile transceiver and a method of detecting movement of the mobile transceiver in a radio system. The radio system includes at least one base station and terminals. The movement of the mobile transceiver is measured by at least one acceleration sensor (114-116) to take the movement of the mobile transceiver onto account in the operation of the radio system.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is a reissue of U.S. patent application Ser. No. 10 / 311,234 (now U.S. Pat. No. 7,079,814), filed Apr. 23, 2003, which is a national stage filing of International Pat. App. No. PCT / FI01 / 00562, filed Jun. 14, 2001, which claims the benefit of Finnish Pat. App. No. 20001453, filed Jun. 19, 2000. FIELD OF THE INVENTION[0002]The invention relates to a solution for detecting movement of a mobile transceiver in a radio system.BACKGROUND OF THE INVENTION[0003]In radio systems, such as the GSM (Global System for Mobile Communication), CDMA (Code Division Multiple Access), WCDMA (Wide Band CDMA), CDMA 2000, PDC (Personal Digital Cellular) and the like, the movement of a mobile terminal is not usually measured in any way but the operations of the whole radio system are designed so that the data transmission connection works in all conditions. In that case operations are performed as if the terminal moved all the time at a ver...
