Claim 6:
7. An apparatus, comprising:
a processor; and
a memory storing instructions that, when executed by the processor, cause the apparatus to:
receive first information sent by a first terminal device, wherein the first information indicates that the first terminal device has limited uplink power;
determine, based on the first information, a second terminal device that provides, in a target cell, a relay service for the first terminal device; and
send second information to a first radio access network device, wherein
the second information indicates the second terminal device that provides, in the target cell, the relay service for the first terminal device,
the first radio access network device belongs to the target cell, and
the first terminal device requires connection to the target cell, wherein

the apparatus is further caused to:
receive third information and fourth information sent by the first radio access network device, wherein
the third information includes a target cell identifier and a first cell radio network temporary identifier (C-RNTI) allocated to the first terminal device, and
the fourth information includes the target cell identifier, a second C-RNTI allocated to the second terminal device, and a random access resource; and

send the third information to the first terminal device; and
send the fourth information to the second terminal device.
