Abstract:
Methods and systems are disclosed for implementing inter-network roam and for querying and network attachment, applied in a network of access identifier and location identifier separation, wherein the method for implementing inter-network roam comprises: after attaching to an ASN of a roaming area network, a roaming terminal sending a first data packet whose destination address is the AID of a destination device to the destination device; after receiving the first data packet, the ASN querying locally AID-RID mapping information, and requesting a roaming gateway to query the RID of the destination device if the RID is not found and the destination device does not belong to the roaming network; the roaming gateway querying the RID from a home network of the destination device and returning to the ASN; according to the RID, the ASN sending subsequent data packets of the roaming terminal to the destination device.
