US 8,478,829 B2 · Asynchronous real-time retrieval of data

Abstract

A data retrieval system includes a gateway server and an access client. The gateway server is communicatively connected to the access client through a network. The gateway server provides a presentation service (PS) and a real-time service (RTS), which cooperate with the access client to retrieve data from a data store and then provide the retrieved data to a user's remote communication device. More particularly, when a user wishes to retrieve data from the data store or to send data to the data store, the user establishes a communication connection between his or her remote communication device and the gateway server, and then requests the desired data from the gateway server. In response, the gateway server sends a command to the access client, instructing it to retrieve the requested data. The access client retrieves the requested data from the data store, and returns the retrieved data to the gateway server. The gateway server then relays the requested information back to the user's remote communication device.

Dependent claims

A method of retrieving data by a wireless device from an electronic mail account server via the Internet, the electronic mail account server being arranged to receive electronic mail data on behalf of said wireless device, the method comprising configuring the electronic mail account server to:

receive device characteristics data comprising an idle time for said wireless device at the electronic mail account server over the Internet, said data enabling the electronic mail account server to determine a timeout period for the wireless device;
determine the timeout period for the device on the basis of said idle time;
responsive to a request for electronic mail data from said wireless device, configuring a timer at the electronic mail account server based on the determined timeout period;
and
in the event that electronic mail data have not been received at the electronic mail account server at the expiry of the timer, transmit a response message to the wireless device,
wherein said response message causes the wireless device to submit a further request to the electronic mail account server for electronic mail data.
