Relay selection method and apparatus and system
A relay selection method and apparatus and a system. The method includes: relay equipment broadcasts relay discovery information, the relay discovery information including identifier information (a relay UE ID) of the relay equipment and identifier information (a cell ID) of a serving cell of the relay equipment, so that remote terminal receiving the relay discovery information selects relay equipment according to the relay discovery information or transmits relay information of discovered relay equipment to an eNB, thus the eNB may select relay equipment for the remote terminal. With certain embodiments, the serving cell may learn a cell where a relay to which the terminal accesses is located, so as to perform configuration for the terminal or perform path switching of downlink data.
1. A relay selection apparatus, applicable to relay equipment, the relay selection apparatus comprising:
a receiver configured to receive a request information transmitted by a remote terminal for unicast traffic communication with a serving cell; and
a transmitter configured to broadcast relay discovery information to the remote terminal according to received request information, the relay discovery information including a first identifier (ID) of the relay equipment and a second identifier (ID) of the serving cell of the relay equipment, wherein the first ID of the relay equipment, the second ID of the serving cell of the relay equipment and a measurement result corresponding to the relay equipment are reported by the remote terminal to a network device that determines the relay equipment among one or more relay equipment after receiving the first ID, the second ID, and the measurement result, the measurement result being determined by the remote terminal.
