Abstract
Mobile-to-mobile connections are being arranged in a wireless telecommunications system comprising at least one mobile station, base stations serving the mobile stations, and at least one gateway. The gateway controls the base stations connected to the gateway and performs a protocol conversion. For mobile-to-mobile connections, a second handover algorithm is stored in the gateway. The data transmitted between two mobile stations served by base stations connected to the same gateway is switched in the gateway without a protocol conversion. If a mobile station is engaged in a data transfer connection with another mobile station visiting the wireless telecommunications system, the mobile station is handed over, when necessary, to a base station proposed by a second handover algorithm.
