2 . The apparatus according to claim 1 , wherein the transmitter further configured to transmit the second identification information to the second terminal equipment.
3 . The apparatus according to claim 1 , further comprising:
a receiver configured to receive first identification information transmitted by the first terminal equipment, the first identification information being used to indicate a first identifier related to the second terminal equipment.
4 . The apparatus according to claim 1 , wherein the second identification information transmitted by the transmitter to the first terminal equipment is carried by a first RRC reconfiguration message, and the second identification information transmitted by the transmitter to the second terminal equipment is carried by a second RRC reconfiguration message.
5 . The apparatus according to claim 1 , further comprising:
a receiver configured to receive first identification information transmitted by the second terminal equipment, the first identification information being used to indicate a first identifier related to the second terminal equipment.
6 . The apparatus according to claim 4 , wherein the first RRC reconfiguration message further includes first identification information being used to indicate a first identifier corresponding to the second identifier.
7 . The apparatus according to claim 3 , wherein the first identification information is carried by SUI or a second RRC message for the first terminal equipment.
8 . The apparatus according to claim 7 , wherein the first identification information is a newly-added information element in the SUI or the second RRC message.
9 . The apparatus according to claim 3 , wherein the first identifier is a L2 ID of the second terminal equipment.
10 . The apparatus according to claim 1 , wherein the second identifier is a local/temporary identifier of the second terminal equipment.
11 . The apparatus according to claim 10 , wherein the local/temporary identifier are denoted by 8 bits.
12 . The apparatus according to claim 4 , the second RRC reconfiguration message is a switch command including related information on switching to a first terminal equipment.
13 . The apparatus according to claim 1 , wherein the first terminal equipment is Relay UE, the second terminal equipment is Remote UE.
14 . The apparatus according to claim 1 , further comprising:
a receiver configured to receive measurement report transmitted by the second terminal equipment, the measurement report includes at least one candidate first terminal equipment ID, serving cell ID of a first terminal equipment and sidelink measurement result, wherein
the processor is further configured to determine to switch the second terminal equipment to being connected to the network device via the first terminal equipment after receiving the measurement report.
15 . The apparatus according to claim 1 , further comprising:
a receiver configured to receive a RRC reconfiguration complete message transmitted by the second terminal equipment via the first terminal equipment, so as to complete the second terminal equipment switching to being connected to the network device via a first terminal equipment.
16 . An information transceiving apparatus, applicable to a second terminal equipment, the apparatus comprising:
a transmitter configured to transmit first identification information to a network device, the first identification information being used to indicate a first identification related to the second terminal equipment; and/or,
a receiver configured to receive second identification information transmitted by the network device, the second identification information being used to indicate a second identifier of the second terminal equipment.
17 . The apparatus according to claim 16 , wherein via a second RRC reconfiguration message, the receiver receives the second identification information transmitted by the network device.
18 . The apparatus according to claim 16 , wherein the apparatus further comprises:
a processor configured to transmit a RRC reconfiguration complete message to the network device via a first terminal equipment, so as to complete switching to being connected to the network device via a first terminal equipment.
19 . The apparatus according to claim 18 , wherein the transmitter further configured to transmit measurement report, the measurement report includes at least one candidate first terminal equipment ID, serving cell ID of a first terminal equipment and sidelink measurement result; the measurement report being used to determine to switch the second terminal equipment to being connected to the network device via the first terminal equipment by the network device.
20 . An information reception apparatus, applicable to a first terminal equipment, the apparatus comprising:
a receiver configured to receive second identification information transmitted by a network device, the second identification information being used to indicate a second identifier of the second terminal equipment, wherein the network device determines to switch the second terminal equipment to being connected to the network device via the first terminal equipment.
