ADDRESS MAPPING METHOD AND ACCESS SERVICE NODE

摘要

The present invention discloses an address mapping method and an Access Service Node (ASN), which are implemented based on an identity and location separation network, wherein the ASN is provided with a commonly used address mapping table including a mapping relationship between commonly used identity identifiers and location identifiers. The method includes: the ASN receives a data message including a target identity identifier; the ASN queries the commonly used address mapping table according to the target identity identifier in the data message; if the target location identifier corresponding to the target identity identifier is found in the commonly used address mapping table, then the ASN forwards the data message according to the target location identifier; if the target location identifier corresponding to the target identity identifier is not found in the commonly used address mapping table, then the ASN interacts with a mapping server to forward the data message. The present invention can reduce data traffic between the ASN and the mapping server, and improve the efficiency of data message processing.
