Patent ID: 8618717

Claim:
A mobile wireless communication device configured to facilitate communication between a host computing device and one or more network access points when the mobile wireless communication device is operatively coupled to the host computing device, the host computing device comprising a processor and a host memory operatively coupled to said processor and adapted for storing one or more Internet protocol addresses received from a corresponding network access point, the mobile wireless communication device comprising: a deletion mechanism stored on a memory of the mobile wireless communication device, wherein at least one of the one or more internet protocol addresses is temporarily deleted by said deletion mechanism, and the mobile wireless communication device configured to transfer the deletion mechanism to the host computing device, the deletion mechanism operatively coupled to said processor and said host memory following said transfer, the deletion mechanism adapted for: presuming that the one or more stored internet protocol addresses are potentially invalid due to a change in location of the mobile wireless communication device; and inhibiting use of said one or more stored internet protocol addresses by deleting the one or more stored internet protocol addresses from said host memory following said presumption, thereby influencing the host computing device to request a new valid internet protocol address; and a restoration mechanism operatively coupled to said processor and said memory, the restoration mechanism adapted for restoring said at least one of one or more temporarily deleted internet protocol addresses to said memory.
