Title: LINK ESTABLISHMENT METHOD AND RELATED DEVICE
Abstract:
Disclosed are a link establishment method and a related device. The method comprises: a relay device receiving, by means of a stub link between the relay device and a remote device, a first access network protocol layer 2 message sent by the remote device; correspondingly generating a second access network protocol layer 2 message according to the first access network protocol layer 2 message and sending the second access network protocol layer 2 message to a network side device; receiving a third access network protocol layer 2 message returned by the network side device in response to the second access network protocol layer 2 message; correspondingly generating a fourth access network protocol layer 2 message according to the third access network protocol layer 2 message and sending the fourth access network protocol layer 2 message to the remote device. A relay device establishes an access network link between a remote device and a network side device so that the remote device can still successfully access the network side device when it is inconvenient for the remote device to directly communicate with the network side device, thereby improving the network access flexibility.
