Abstract

A time of arrival measurement apparatus is used to measure the time of arrival of a radio signal transmitted by a mobile communication station operating in a wireless mobile communication network. The apparatus is provided with information indicative of a predetermined point in time at which the radio signal is to be transmitted. The time of arrival measurement apparatus monitors for arrival of the radio signal only during a period of time after the predetermined point in time.

Claims

1. A method of using a time of arrival measurement apparatus to measure the time of arrival of a radio signal transmitted by a mobile communication station operating in a wireless mobile communication network, comprising:

providing the time of arrival measurement apparatus with information indicative of a predetermined point in time at which the radio signal is to be transmitted; and

using the time of arrival measurement apparatus to monitor for arrival of the radio signal only during a period of time after said predetermined point in time.
