A resource selection apparatus and communication system. The apparatus includes: a first selection unit configured to select a resource for performing D2D communication from a resource pool configured in a second mode by a first eNB or a second eNB after UE is disconnected from the first eNB, in a first period from the UE receives physical layer out-of-synchronization indication information to the UE receives a first resource allocated in a first mode by the second eNB reestablishing a connection with the UE, or in a second period from the UE receives configuration information triggering the UE to be handed over to the second eNB to the UE receives a first resource allocated in a first mode by the second eNB, or in a third period from the UE initializes reestablishment to the UE receives a first resource allocated in a first mode by the second eNB reestablishing a connection with the UE, or in a fourth period from the UE transmits a reestablishment request to the UE receives a first resource allocated in a first mode by the second eNB reestablishing a connection with the UE. With the resource selection apparatus and communication system, the UE is facilitated to select a corresponding resource for the D2D communication, so as to ensure continuity of the D2D communication, and avoid disconnection. |
