A method for ordering a taxi (16, 33) through a mobile telecommunications system (PLMN). The taxies are provided with a mobile phone of said system. In the mobile telecommunications system, location management (MM) is maintained in order to establish a connection to each mobile phone. The taxi center (TC) receives a digital order message (OM) from the subscriber terminal (11 - 14) of the client (A) and defines, on the basis of the order message, the order address of the taxi, and on the basis of said address, the taxi group (T10) which at least in the beginning is formed of taxies that are located near the order address and are in the state of readiness. Without establishing a speech connection, the taxi center sends a call (CL) to the taxies of said group. If none of the taxies answers the call within a predetermined period of time, the group is reformed, and the call is repeated. The definition of those taxies that are located in the vicinity of the order address is advantageously carried out by means of a location server (LS, LS'), where the terminal coordinates are maintained at an accuracy that is better than the accuracy produced by the location management (MM). |
