Method and device for establishing association between terminal devices

A method for establishing an association between terminal devices, comprising:

• receiving, by a second terminal device, a cluster identifier (ID) transmitted by a first terminal device, the cluster ID being used to temporarily identify a cluster, to which the first terminal device pertains, the cluster ID being allocated to the first terminal device and transmitted to the first terminal device by a network device when determining that the first terminal device has capabilities of receiving and forwarding data;
• transmitting, by the second terminal device, association request information to the first terminal device, the association request information carrying device information of the second terminal device;
• and
• when receiving association confirmation information transmitted by the first terminal device, storing, by the second terminal device, the cluster ID to establish the association with the first terminal device, wherein the association confirmation information is transmitted to the second terminal device by the first terminal device when a user or the first terminal device determines, according to the device information, to establish the association between the first terminal device and the second terminal device.

A terminal device, comprising:

• a processor;
• and
• a memory storing instructions, which, when executed by the processor, cause the processor to perform one or more actions comprising:
• transmitting information of terminal capabilities to a network device, the information of terminal capabilities being used to indicate that the terminal device has capabilities of receiving and forwarding data, receiving confirmation information for confirming that the terminal device has the capabilities of receiving and forwarding data from the network device;
• and establishing an association with a second terminal device according to the confirmation information.
