Mobile device handoff optimization

摘要

The invention is directed to optimization of a seamless transition of a mobile device from a 3G eHRPD network to a 4G network in a failure scenario. The mobile device is authenticated and attached to the 3G eHRPD network. Upon the mobile device initiating a first handoff attempt to access and access the 4G network, the subscriber profile database is accessed to determine whether a packet gateway identifier is stored on the database. If the identifier is not stored on the database, the first handoff attempt of the mobile device to access the 4G network is denied. Upon being denied, the packet gateway is triggered to communicate the packet gateway identifier in an authorization request so that the identifier can be stored in the subscriber profile database. A subsequent attempt of the mobile device to handoff to the 4G network is allowed, as the packet gateway identifier is now stored on the database.

1. A method for optimizing a seamless transition of a mobile device from a 3G network to a 4G network in a failure scenario, the method comprising:
authenticating the mobile device to the 3G network; at a network component, determining that the mobile device is initiating a first handoff attempt to access the 4G network; accessing a subscriber profile database to determine whether a packet gateway identifier associated with the mobile device is stored on the subscriber profile database; upon determining that the packet gateway identifier associated with the mobile device is not stored on the subscriber profile database, denying the first handoff attempt by the mobile device to access the 4G network; based on the first handoff attempt by the mobile device to access the 4G network being denied, triggering an authorization request that comprises the packet gateway identifier associated with the mobile device, the packet gateway identifier being forwarded to the subscriber profile database; storing the packet gateway identifier on the subscriber profile database; determining that the mobile device is initiating a second handoff attempt to access the 4G network; and authorizing the second handoff attempt of the mobile device to access the 4G network based on the packet gateway identifier associated with the mobile device being stored on the subscriber profile database.
