To overcome the problem of limited backhaul capacity and limited wireless channel capacity when downloading videos to smart phones, a method for transmission of data across a mobile telecommunications network, includes providing each Smartphone or other user station (Ua-Ud) with a memory cache (12) and a download app (10), and providing a server (2) in the core network with a server cache memory (16) and a download control app (14). Each user registers with the server, the server gathers information of internet web sites (URLn) accessed by the users from which downloads may be made, monitors the websites, and as and when updates appear on the websites, selectively downloads the updates in the server cache. There is then established a common data channel from the server, across base stations (3), to the users in order to download the updates to the user's memory cache (12). |

1. A method for transmission of data across a mobile cellular telecommunications network, the network comprising a plurality of user stations (Ua-Ud), a plurality of cell stations, and a central network, wherein each user station includes a user memory storage device, and the central network including a server, which includes server memory storage device, the method comprising:
said server registering each user station, said server maintaining a record of each user station, and maintaining a list for each user station of Internet web sites (URLn) accessed by the user station from which downloads may be made, said server monitoring said websites, and as and when new data items appear on said websites, selectively storing said data items in said server memory storage device, and selectively establishing a common data channel from said server, across said cell stations, to said user stations in order to download selected said data items on a non-streaming basis to the user memory storage device of each said user station, so that when a user subsequently requests access to said data item, the user is directed to the corresponding data item stored in said user memory storage device; wherein the common data channel is selectively established when the server receives a predetermined volume of update data. |
