摘要

The present invention relates to a method for improving the use of proximity services in a public land mobile network. The public land mobile network includes an access network, the access network has a base transceiver station for a geographical area, and a plurality of user equipments in the geographical area receive control signals from the base transceiver station, and a plurality of users The device is a proximity service compatible user device, and when the proximity service function of the user device is activated, proximity service activation information is stored in or transmitted by the public land mobile network, and the user device When the proximity service function is activated, the user equipment emits a proximity service discovery signal, and the method includes the following steps: a base transceiver station to a first user equipment of the plurality of user equipments. A first step of receiving relevant first proximity service activation information; A second step in which the transceiver station receives second proximity service activation information related to a second user equipment of the plurality of user equipments, and a plurality of proximity service broadcast information from the base transceiver station in the geographical area. A third step transmitted to the user equipment and the first user equipment starts emitting a first proximity service discovery signal and the second user equipment starts emitting a second proximity service discovery signal And a fourth step.
