METHOD FOR ENHANCING THE USE OF PROXIMITY SERVICES IN A PUBLIC LAND MOBILE NETWORK, USER EQUIPMENT FOR USE IN A GEOGRAPHIC AREA OF AN ACCESS NETWORK OF A PUBLIC LAND MOBILE NETWORK, BASE TRANSCEIVER STATION FOR ENHANCING THE USE OF PROXIMITY SERVICES, PROGRAM AND COMPUTER PROGRAM PRODUCT

摘要

The invention relates to a method for enhancing the use of proximity services in a public land mobile network, wherein the public land mobile network comprises an access network, the access network having a base transceiver station for a geographic area, wherein a plurality of user equipments within the geographic area receive control signals from the base transceiver station, wherein the plurality of user equipment are proximity services enabled user equipments, wherein – in case of an activated proximity services functionality of a user equipment – a proximity services activation information is either stored in the public land mobile network or sent by that user equipment, wherein – in case of an activated proximity services functionality of a user equipment – that user equipment emits a proximity services discovery signal, wherein the method comprises the following steps: -- in a first step, the base transceiver station receives a first proximity services activation information related to a first user equipment of the plurality of user equipments, -- in a second step, the base transceiver station receives a second proximity services activation information related to a second user equipment of the plurality of user equipments, -- in a third step, a proximity services broadcast information is sent from the base transceiver station to the plurality of user equipments within the geographic area, -- in a fourth step, the first user equipment starts to emit a first proximity services discovery signal and the second user equipment starts to emit a second proximity services discovery signal.
