Continuous cache service in cellular networks

摘要

A technique for transmitting an object to a mobile device is provided. In response to the mobile device moving from a first area serviced by a first cache to a second area serviced by a second cache, the first cache transmits the object stored in the first cache to the second cache. The first cache transmits instructions to the second cache that cause the second cache to forward the object to the mobile device in the second area.

1. A method for transmitting an object to a mobile device, the method comprising:
in response to the mobile device moving from a first area serviced by a first cache that stores a same object to a second area serviced by a second cache, receiving by the second cache a transmission context of the same object from the first cache; the second cache locally storing the same object as the first cache; transmitting by the second cache the same object locally stored in the second cache to the mobile device in the second area according to the transmission context received from the first cache; transmitting a discovery request message indicating that the second cache is searching to discover a previously servicing cache that previously serviced the mobile device prior to moving to the second area; and receiving a discovery response message at the second cache from the first cache in which the discovery response message indicates that the first cache was previously servicing the mobile device.
