Abstract
The invention relates to a method for locating a mobile station (5) my means of radio signals between the mobile station (5) and the mobile station network (1a, 2a, 3a, 4a) by forming separate location channels in addition to the communication channels. The location channels are, among others, the location access channel and the location receipt channel. The access channel is used to send a burst, which includes the identification of the mobile station (5), such as the International Mobile Subscriber Identification (IMSI). The location channels can be used in the locating methods based on the angle of arrival, time difference and transition time of the radio transmission, for example.
