Embodiment Construction

[0039] figure 1 Components of the mobile radio terminal 1 and the base station 2 that are relevant for understanding the invention are shown in the form of a functional block diagram. Here, as long as the traditional method and the improved method according to the present invention are involved, the transmission of the command and confirmation message inside the base station is shown by dashed and solid lines, respectively. Functional units which have been modified from the prior art for implementing the invention are indicated by double boxes.

[0040] The base station 2 is one of a plurality of devices of a mobile radio network based on the GSM standard, not shown further. Correspondingly, the mobile station 1 is also designed to establish a connection via the GSM network.

[0041] In the description of the components, the conventional sequence for determining the signal runtime in the terminal 1 will first be explained. The improvement according to the invention is discu...

Abstract

A method for detecting a signal propagation time between a mobile radio terminal and a base station in a mobile radio network in a mobile radio terminal, particularly for the purpose of localizing the mobile radio terminal which inserts a propagation time detection information item into a channel request message in order to signal to the base station that no channel reservation is necessary, and that only the propagation time detection needs to be carried out, so as to achieve significantly reduced loading of network resources.

Description

technical field [0001] The invention relates to a method for determining the runtime of a signal between a mobile radio terminal and a base station of a mobile radio network in a mobile radio terminal, in particular for positioning a mobile radio terminal, the mobile radio terminal For example, it can also be a wireless module. Background technique [0002] In order to establish a connection between a mobile radio terminal of a mobile radio network and a base station, it is necessary to determine the time delay of the signal transmission between the two. For example, in the GSM system, this signal runtime is required to synchronize the uplink bursts of the terminals with the time slots of the base station. [0003] For this purpose, the signal runtime is determined in the base station on the basis of the access bursts (Access Burst) sent by the mobile station. Channel request messages, ie "channel request messages" in the GSM system, are transmitted as such access bursts. ...
