Method and apparatus for flexible fast network switching

摘要

Disclosed herein are methods and systems for flexible fast network switching. In an embodiment, a wireless-communication device has a first chipset compatible with first and second bands and a second chipset compatible with the first band and a third band. The device selects a mode for switching among two or more of the bands. In a first mode with respect to the first and second bands, the device obtains service on the first band via the first chipset. In the first mode with respect to the first and third bands, the device obtains service on the first band via the second chipset. In a second mode with respect to the first and second bands, the device obtains service on the first band via the second chipset. In the second mode with respect to the first and third bands, the device obtains service on the first band via the first chipset.

主权项

1. A method carried out by a wireless-communication device having a first chipset and a second chipset, the first chipset being compatible with each of a first wireless band and a second wireless band, the second chipset being compatible with each of the first wireless band and a third wireless band, wherein the first, second, and third wireless bands are respectively associated with corresponding first, second, and third networks, the method comprising:
selecting a network-switching mode from among a plurality of network-switching modes that each implement switching among two or more of the first, second, and third networks, the plurality of network-switching modes comprising a first-network switching mode and a second network-switching mode; responsive to selecting the first network-switching mode with respect to the first and second networks, obtaining wireless service on the first wireless band via the first chipset; responsive to selecting the first network-switching mode with respect to the first and third networks, obtaining wireless service on the first wireless band via the second chipset; responsive to selecting the second network-switching mode with respect to the first and second networks, obtaining wireless service on the first wireless band via the second chipset; and responsive to selecting the second network-switching mode with respect to the first and third networks, obtaining wireless service on the first wireless band via the first chipset.
