Fig. 2 is trunking defining method embodiment one flow chart that the present invention is based on D2D communication; The executive agent of the method is base station, and software and/or hardware implementing can be passed through in this base station.Please refer to Fig. 2, the method can comprise:
Basic candidate relay cluster tool is determined in the UE that S201, base station are served in base station, the channel quality of the UE in the candidate relay cluster tool of basis meets preset quality requirement, candidate relay cluster tool is determined in base station in basic candidate relay cluster tool, and the characteristic parameter of the UE in candidate relay cluster tool meets parameter preset requirement;
S202, base station send candidate selection message to the UE in candidate relay cluster tool, discovery message is sent to outlying UE to make the UE in candidate relay cluster tool, trunking set is obtained according to discovery message to make outlying UE, and at trunking set determination relaying UE, outlying UE sends service request information to relaying UE, sends authorization request message to make relaying UE to base station;
S203, base station receive the authorization request message comprising outlying UE mark that relaying UE sends, authorization request message authorizes relaying UE to provide relay services for outlying UE for asking base station, base station sends authorization response message to relaying UE, and authorization response message is used to indicate relaying UE for outlying UE provides relay services.
In the embodiment shown in Figure 2, optionally, the channel quality of UE can comprise: Reference Signal Received Power (ReferenceSignalReceivingPower, RSRP), and/or receive Reference Signal Received Quality (ReferenceSignalReceivingQuality, RSRQ), accordingly, preset quality requires: between UE and base station, the RSRP of signal transmission meets default received power requirement, and/or between UE and base station, the RSRQ of signal transmission meets the requirement of preset reference signal receiving quality; Optionally, the characteristic parameter of UE can comprise dump energy and translational speed, accordingly, the parameter preset that the characteristic parameter of UE meets requires to comprise: the translational speed of condition and UE that dump energy is greater than default charge value is less than the condition of the default translational speed of UE, further, the characteristic parameter of UE can also comprise the energy consumption index of UE, and accordingly, the condition that the characteristic parameter of UE meets also comprises: the energy consumption index of UE meets the condition of default horsepower requirements.
It should be noted that, in actual application, can arrange according to actual needs the signal quality of UE, UE channel quality meet preset quality requirement, the parameter preset requirement of the characteristic parameter of UE and the characteristic parameter demand fulfillment of UE, the present invention does not do concrete restriction to this.
In the process of practical application, base station can obtain channel quality and/or the characteristic parameter of UE by implementation feasible as follows:
A kind of feasible implementation: base station sends a request message to UE, sends channel quality and/or the characteristic parameter of UE to make UE to it;
Another kind of feasible implementation: base station obtains channel quality and/or the characteristic parameter of UE by modes such as measurements;
Another feasible implementation: base station obtains channel quality and/or the characteristic parameter of UE by Third party system.
It will be appreciated by persons skilled in the art that in the process of practical application, base station can according to actual needs, and obtained channel quality and/or the characteristic parameter of UE by different modes, the present invention is not specifically limited this.
In actual application, determine the efficiency of trunking to improve outlying UE, base station according to the channel quality of a fairly large number of UE and characteristic parameter, the candidate relay cluster tool that quantification is less; Concrete, the channel quality of the UE that base station is served according to base station, the basic candidate relay cluster tool that channel quality meets preset quality and requires is determined in the UE of base station service, again according to the characteristic parameter of UE in basic candidate relay cluster tool, in basic candidate relay cluster tool, determine that characteristic parameter meets the candidate relay cluster tool of parameter preset requirement.
