<p>An address resolution method and device, and an information transmission method. The address resolution method includes: after a source access server (ASR) to which source user equipment (UE) belongs has received an address resolution protocol (ARP) broadcasting request message from the source UE, applying the location identifier of target UE to secondarily encapsulate the ARP broadcasting request message, and sending the secondarily encapsulated APR broadcasting request message to a target ASR to which the target UE belongs; and the target ASR decapsulating the received secondarily encapsulated ARP broadcasting request message, sending the obtained ARP broadcasting request message to the target UE to acquire the media access control (MAC) address of the target UE, and sending to the source UE the MAC address of the target UE via the source ASR. The present application can highly efficiently and rapidly acquire the MAC address of the UE which is not in a unified broadcasting domain.</p> |
