However, Shan et al, does not specifically teach the features of analyzing the discovery message through at least one layer of the PC5-S layer and a PC5-Radio Resource Control layer,

On the other hand, Wang et al, from the same field of endeavor, discloses the features of analyzing the discovery message through at least one layer of the PC5-S layer and a PC5-Radio Resource Control layer (the remote UE may receive the MIB-SL message or a new RRC message from the adjacent relay node, and determine whether or not the D2D UE has a relay capability in accordance with the contents carried in the MIB-SL message or the new RRC message; paragraph 0017, 0124), wherein the analyzing the discovery message through at least one layer of the PC5-S layer and a PC5-RRC layer, comprises: analyzing a first discovery message through the PC5-S layer and obtaining first message content (the relay node may receive the relay discovery message from the adjacent remote UE, and determine, in accordance with the carried in the relay discovery message, whether or not to broadcast the relay discovery response message to the remote UE; the MSB-SL message may have the following format, upon the receipt of the information, the remote node may select and access to the other relay node ; paragraph 0033, 0090, 0124-0125), wherein the first message content carries a first relaying-terminal-selection condition (the relay node may receive the relay discovery message from the adjacent remote UE, and determine, in accordance with the contents carried in the relay discovery message, whether or not to broadcast the relay discovery response message to the remote UE; furthermore, the relay node may decide to activate the relay function in accordance with such factors as the network-side authentication result, the network load condition, its own service handling capability, the signal quality of the U.sub.U interface ; paragraph 0124, 0115-0116); and wherein the first relaying-terminal-selection condition is a relaying-terminal-selection condition commonly used by a layer-two relay and a layer-three relay (receive through the transceiver 1610 a relay discovery message from a remote UE within a predetermined range, the relay discovery message carrying target relay indicators and relay node identifiers; and in the case that its own identifier successfully matches any target relay indicator and relay node identifier in accordance with the relay discovery message, transmit through the transceiver 1610 a relay discovery response message to the remote UE, to indicate the remote UE to establish the D2D communication; paragraph 0151, 0099-0100), or a relaying-terminal-selection condition specially used by the layer-two relay (the UE is the relay node through a RRC message via the PC5 interface, the RRC message carrying a relay indicator and an identifier of the UE; or notify the other UEs currently using the D2D link that the UE is the relay node through an MIB-SL message via the PC5 interface, the MIB-SL message carrying the relay indicator and the identifier of the UE; paragraph 0149), or a relaying-terminal-selection condition specially used by the layer-three relay (in the case that the first UE determines that its own running state meets a predetermined condition in accordance with a measurement result, determining the first UE as a relay node paragraph 0099), the relaying-terminal-selection condition is configured for an opposite terminal of the second UE to judge a relaying selection (in the case that the first UE determines that the relay privilege is allowed to be used in accordance with the network-side authentication result with respect to its own relay privilege, determining the first UE as the relay node; in the case that the first UE determines that the load of the current access network is smaller than a predetermined threshold, determining the first UE as the relay node ; in addition, notifying the other UEs currently using the D2D link that the UE is the relay node via the PC5 interface, the processor 1600 is further configured to: in the case that its own running state does not meet the predetermined condition in accordance with the measurement result, notify the other UEs currently using the D2D link that the UE is not the relay node via the PC5 interface; and periodically measure its own running state; paragraph 0100, 0150).
Wang et al, also teaches that the first UE may determine the network load condition, its own service handling capability, the signal quality of the U.sub.U interface and the geographical position of the first UE in the case of accessing to the network, that the first UE is the relay node, and decide to activate the relay function. The MIB-SL message may carry information about a relay indicator and a relay ID. The relay indicator may be a Boolen value, and in the case that the relay indicator is “1”, it means that the relay function is to be activated (paragraph 0106-0107). Furthermore, the notification unit 122 is configured to notify the other UEs currently using the D2D link that the UE is the relay node through a RRC message via the PC5 interface, the RRC message carrying a relay indicator and an identifier of the UE; or notify the other UEs currently using the D2D link that the UE is the relay node through an MIB-SL message via the PC5 interface, the MIB-SL message carrying the relay indicator and the identifier of the UE.

It is impossible for the UE to select an appropriate UE-to-network relay node or UE-to-UE relay node to access to the network or perform the communication; hence, the data transmission efficiency and accuracy for the D2D discovery and D2D communication are severely limited. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to apply the technique of Wang to the communication system of Shan in order to provide a method for determining the relay node for the data transmission during the D2D discovery or D2D communication for improving the D2D discovery or D2D communication efficiency.

determines a first link failure in step S14A; judges that a first condition is satisfied in step S15A, and generates a first BSR; paragraph 0626); the second relaying-terminal-selection condition is another relaying-terminal-selection condition commonly used by the layer-two relay and the layer-three relay (a first processor, as a response to a first condition being satisfied, generating a first BSR; and a first transmitter, transmitting a first radio signal, the first radio signal carrying the first BSR; furthermore, the first communication device 450 at least: as a response to a first condition being satisfied, generates a first BSR; transmits a first radio signal, the first radio signal carries the first BSR; herein, the first condition is that a difference value between a buffer size for a first logical channel set and a first reference buffer size exceeds a first threshold; paragraph 0054-0055, 0621-0622), or another relaying-terminal-selection condition specially used by the layer-two relay (transmits a second data unit set through a second channel set in step S13A; determines a first link failure in step S14A; judges that a first condition is satisfied in step S15A, and generates a first BSR; paragraph 0626), or another relaying-terminal-selection condition specially used by the layer-three relay(the first message is used to trigger the second message; the first radio bearer comprises a first PDCP entity and a first RLC bearer; a transmission of the second message is through a second PDCP entity and the first RLC bearer; the first message is used to trigger associating the first RLC bearer to the second PDCP entity; monitors a third data unit set via an air interface, and the third data unit set carries a second message; as a response to the behavior of determining a first connection failure, transmits a second data unit set via an air interface; paragraph 0626-0628; the relaying-terminal-selection condition is configured for an opposite terminal of the first UE to judge a relaying selection (receives a first data unit set through a first channel set in step S12A; transmits a second data unit set through a second channel set in step S13A; determines a first link failure in step S14A; judges that a first condition is satisfied in step S15A, and generates a first BSR; transmits a first radio signal in step S16A, and the first radio signal carries a first BSR; paragraph 0685), wherein the first message content and the second message content correspond to different layer-two identifiers the first message is used to trigger associating the first RLC bearer to the second PDCP entity; monitors a third data unit set via an air interface, and the third data unit set carries a second message; as a response to the behavior of determining a first connection failure, transmits a second data unit set via an air interface; paragraph 0626-0628). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to apply the technique of Zhang to the modified system of Shan and Wang in order to provide a relay reselection method for monitoring a triggering condition for notifying a remote terminal to perform relay reselection for the purpose of improving the transmission quality of the source node and the remote node.
