Abstract
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.
Claims10
A method for transmitting an object to a mobile device, the method comprising:
- in response to the mobile device being moved from a first area serviced by a first cache to a second area serviced by a second cache, transmitting, from the first cache, the object stored in the first cache to the second cache;
- transmitting a discovery request message from the first cache, wherein the discovery request message indicates that the first cache is searching to discover any cache now serving the mobile device subsequent to the mobile device being moved from the first area;
- receiving, by the first cache, a discovery response message back from the second cache now servicing the mobile device;
- and
- transmitting, from the first cache to the second cache, instructions that cause the second cache to forward the object to the mobile device in the second area.
A system for transmitting an object to a mobile device, the system comprising:
- a network;
- a first cache configured to communicate over the network and store the object;
- in response to the mobile device moving from a first area serviced by the first cache to a second area serviced by a second cache, the first cache is configured to transmit the object stored in the first cache to the second cache;
- the first cache is configured to transmit a discovery request message indicating that the first cache is searching to discover any cache now servicing the mobile device since the mobile device has moved from the first area;
- and
- the first cache is configured to receive a discovery response message back from the second cache now servicing the mobile device;
- and
- the first cache is configured to transmit instructions to the second cache that received the object from the first cache in which the instructions cause the second cache to forward the object to the mobile device in the second area.
