Abstract

Disclosed is a communication system for positioning of a terminal device. The communication system includes at least three leaky coaxial cables, a server device for determining a position of a terminal device in response to a receipt of data from the terminal device through at least two coaxial cables. The server device is arranged to determine an indicator value representing the at least two coaxial cables through which the data from the terminal device is received and to compare the indicator value to change patterns stored in data storage accessible to the server device, and in response to a match in a comparison to generate data representing the position of the terminal device. Also disclosed is a method for positioning the terminal device.

First claim

What is claimed is:

1. A communication system for positioning of a terminal device, the communication system comprising:
at least three leaky coaxial cables, each of the at least three leaky coaxial cables having an inner conductor, an outer conductor and isolation layer between the inner conductor and the outer conductor, wherein the outer conductor of each of the at least three leaky coaxial cables comprises at least one slot, the slots arranged consecutive to each other along longitudinal axes of the at least three leaky coaxial cables to leak radio frequency signals, and
a server device for determining a position of a terminal device in response to a receipt of data from the terminal device through at least two of the at least three leaky coaxial cables collected respectively at a first point in time and a later second point in time,
wherein the server device is arranged to determine an indicator value representing the at least two leaky coaxial cables through which the data from the terminal device is received and to compare the indicator value to change patterns stored in data storage accessible to the server device, and in response to a match in a comparison to generate data representing the position of the terminal device.

2. A method of positioning of a terminal device communicating with a communication system, the communication system comprising at least three leaky coaxial cables, each of the at least three leaky coaxial cables having an inner conductor, an outer conductor and isolation layer between the inner conductor and the outer conductor, wherein the outer conductor of each of the at least three leaky coaxial cables comprises at least one slot, the slots arranged consecutive to each other along longitudinal axes of the at least three leaky coaxial cables to leak radio frequency signals, the method comprising:
receiving, by the server device, data from the terminal device through at least two of the at least three leaky coaxial cables collected respectively at a first point in time and a later second point in time,
determining, by the server device, an indicator value representing the at least two leaky coaxial cables through which the data from the terminal device is received, and
comparing the indicator value to change patterns stored in data storage accessible to the server device, and in response to a match in a comparison generating data representing the position of the terminal device.

3. The system of claim 1 , wherein the change patterns stored in data storage accessible to the server device indicate both a vertical and a horizontal position of the terminal device and the generated data representing the position of the terminal device includes both the vertical and the horizontal position of the terminal device.

4. The method of claim 2 , wherein the change patterns stored in data storage accessible to the server device indicate both a vertical and a horizontal position of the terminal device and the generated data representing the position of the terminal device includes both the vertical and the horizontal position of the terminal device.
