Method for establishing connection by terminal, apparatus, and system

A method for establishing a connection by a terminal, comprising:

• receiving, by a second wireless terminal, a first message comprising identifier information sent by a first wireless terminal, wherein the identifier information is obtained by the first wireless terminal after the first wireless terminal acquires a first Media Access Control (MAC) address of the second wireless terminal and according to at least the first MAC address;
• determining, by the second wireless terminal, whether the identifier information in the first message is correct;
• and
• sending, by the second wireless terminal, a first response message comprising a second MAC address of the second wireless terminal to the first wireless terminal when the identifier information comprised in the first message is correct, wherein the second MAC address is a current MAC address of the second wireless terminal.

A wireless terminal, comprising:

• a processor configured to acquire a first Media Access Control (MAC) address of a second wireless terminal;
• a transmitter coupled to the processor and configured to send a first message comprising identifier information such that the second wireless terminal receives the first message and verifies the identifier information, wherein the identifier information is obtained by the wireless terminal according to at least the first MAC address;
• a receiver coupled to the processor and configured to receive a first response message comprising a second MAC address of the second wireless terminal sent by the second wireless terminal, wherein the second MAC address is a current MAC address of the second wireless terminal, and wherein the first response message is a message sent by the second wireless terminal after the second wireless terminal successfully verifies the identifier information, and
• wherein the processor is further configured to communicate with the second wireless terminal according to the second MAC address of the second wireless terminal received by the receiver.
