Notifying a wireless communication system about previously registered wireless communication systems

摘要

Embodiments disclosed herein provide systems and methods that notify a current wireless communication network about a previous wireless communication network. In a particular embodiment, a wireless device wirelessly registers with a first wireless communication system to obtain first registration data. The wireless device stores the first registration data and wirelessly communicates over the first wireless communication system. The communications are then terminated with the first wireless communication system. After terminating the wireless communications with the first wireless communication system, the wireless device wirelessly registers with a second wireless communication system to obtain second registration data and stores the second registration data. The wireless device transfers the first registration data to the second wireless communication system and receives user information from the second wireless communication system. The second wireless communication system used the first registration data to retrieve the user information from the first wireless communication system.

主权项

1. A wireless communication device comprising: a wireless communication interface configured to individually communicate with a plurality of different wireless networks; a data processing system configured to direct the wireless communication interface to register the wireless communication device with individual ones of the wireless networks; the data processing system further configured to store registration data from the wireless registrations that identifies the wireless networks and that identifies the wireless communication device within the wireless networks; the data processing system further configured to direct the wireless communication interface to transfer the stored registration data that identifies the wireless networks and the wireless communication device when registering with at least one of the wireless networks; and wherein the wireless communication interface is configured to receive undelivered user information transferred between the wireless networks in response to the transfer of the stored registration data.
