The present invention relates to a method for deciding to handover a user equipment in a mobile communication network, wherein the mobile communication network comprises an access network and a core network, wherein the access network comprises a plurality of base stations, wherein at least one of the base stations is connected to one or more proximity service relays providing proximity service functionality like device-to-device communication, and wherein said user equipment is directly and/or indirectly via one of said proximity service relays, connected to one of the base stations, comprising the steps of a) Storing context information of said user equipment and said one or more proximity service relays in one or more core network entities and/or access network entities, b) Determining the location of said user equipment based on measurement reports of said user equipment, c) Checking whether one or more of the proximity service relays connected to the same and/or to another, preferably neighboring, base station can provide a proximity service connection for said user equipment based on the stored context information and/or based on available connection parameters, d) Matching the locations of said user equipment and one or more of said proximity service relays based on measurement reports of said one or more proximity service relays, e) Determining whether said user equipment can be served by one or more of the proximity service relays with a higher communication quality, and f) Deciding to handover the user equipment to one of the proximity service relays based on the results of steps c)-e) for establishing a proximity service connection between said proximity service relay and said user equipment. |
