Problems solved by technology

This delay is caused by electronic components and lines between the baseband part and the antenna unit
[0004] However, state-of-the-art solutions in terms of the temporal characteristics of the signal transmitted from the base station are not accurate enough to meet the strict temporal characteristic requirements
The above deficiencies arise due to the unpredictable nature of the electronics in the wireless transmitter, resulting in unpredictable variations in the signal propagation time between the baseband section and the base station antenna
For example, the lack of accuracy of time characteristics leads to the inaccuracy of measuring the signal propagation time between the base station and the mobile station, which leads to the error of the position information of the mobile station

Embodiment Construction

[0022] A simplified structure of a telecommunications system 100 at the network element level is illustrated in FIG. 1 . The radio-independent layer of the telecommunications system is represented by a mobile switching center (MSC) 150 and a gateway mobile services switching center (GMSC) 152 located between the mobile switching center 150 and an external network 154, an example of which is Public Land Mobile Network (PLMN) or Public Switched Telephone Network (PSTN). The telecommunications system 100 may also comprise packet switched network elements such as a Serving GPRS Support Node (SGSN) and a Gateway GPRS Support Node (GGSN) for supporting GPRS (General Packet Radio Service).

[0023] The tasks performed by the mobile services switching center 150 include: switching, paging, user equipment location registration, handover management, collection of user billing information, encryption parameter management, frequency allocation management, and echo cancellation. Mobile sw...

Abstract

A time adjustment method and mechanism, a time stamping method and mechanism and a telecommunication system are provided. The invention is based on performing a power measurement in the base station on a signal generated in the base station, and providing the signal with time characteristics proportional to a time reference received in the base station. Embodiments of the invention enable accurate synchronization of a base station and precise positioning of mobile stations.

Description

technical field [0001] The present invention relates to a time adjustment method in a telecommunication system, a time marking method in a telecommunication system, and a telecommunication system. Background technique [0002] In modern telecommunication systems, the timing and time stamping of signals transmitted from base stations in the telecommunication system can be used for purposes such as synchronization and positioning. [0003] In prior art time-stamp processing techniques, by using the point in time at which the signal is generated in the baseband section of the base station transmitter, and possibly also information about the delay between the generation of the signal in the baseband section and the transmission of the signal from the base station antenna unit, it is determined The transmission time of the signal transmitted from the base station. This delay is caused by electronic components and wiring between the baseband section and the antenna unit. [0004...
