The embodiment of the present invention discloses a link establishment method and related equipment, which includes: the relay device receives the first access network protocol layer 2 message sent by the remote device through the terminal link between the relay device and the remote device; generates the second access network protocol layer 2 message corresponding to the first access network protocol layer 2 message and sends the second access network protocol layer 2 message to the remote device. Network-side devices; receiving third access network protocol layer 2 messages returned by network-side devices in response to second access network protocol layer 2 messages; generating fourth access network protocol layer 2 messages corresponding to third access network protocol layer 2 messages and sending fourth access network protocol layer 2 messages to the remote devices. The access network links between remote devices and network-side devices are established by relay devices, which makes it inconvenient for remote devices to communicate directly with network-side devices, and can also successfully access network-side devices to improve network access flexibility.
