Patent ID: 8923260

Claim:
A method comprising: receiving one or more messages from a mobile device at a mobility gateway over a first network link, the one or more messages containing a user identifier, a link layer identifier, and a device identifier; storing the user identifier, the link layer identifier, and the device identifier at the mobility gateway; receiving a subsequent network attach request containing second received identifiers, including at least a user identifier, a link layer identifier, and a device identifier; comparing the stored set of identifiers with the second received identifiers to determine: whether there is a first match between the stored user identifier and the second received user identifier, whether there is a second match between the stored link layer identifier and the second received link layer identifier, and whether there is a third match between the stored device identifier and the second received device identifier; and establishing one or more sessions from a previous mobility binding at the mobility gateway if there is the first match and the third match, and not the second match.
