Abstract

A wireless router employing a technique to couple a plurality a host services or host systems and a plurality of wireless networks. A method to route data items between a plurality of mobile devices and a plurality of host systems through a common wireless router. A point-to-point communication connection is preferably established between a first host system and a common wireless router, a mobile network message at a mobile device is generated, the mobile network message is transmitted via a wireless network to the common wireless router which in turn routes a data item component of the mobile network message to the appropriate host service.

Claims

1. A method of controlling the transmission of data between a host service and a mobile device, comprising:

receiving the data at a wireless router and formatting the data for transmission to the mobile device via a wireless network connection between the wireless router and a wireless network;

transmitting the formatted data to the wireless network;

receiving delivery information from the wireless network at the wireless router, the delivery information indicating whether or not the formatted data has been successfully received at the mobile device;

if the delivery information indicates that the formatted data has not been received at the mobile device, then transmitting a flow control message from the wireless router to the host service indicating that the data was not received at the mobile device, the flow control message causing the host service to cease further data transmissions for the mobile device.

2. The method of claim 1, further comprising:

receiving delivery information from the wireless network indicating that the formatted data has been received at the mobile device; and

transmitting another flow control message from the wireless router to the host service indicating that the data is received at the mobile device, the flow control message causing the host service to continue further data transmissions for the mobile device.

3. The method of claim 2, further comprising:

queuing data for the mobile device at the host system in response to the flow control message indicating that the data is not received at the mobile device; and

upon receiving the another flow control message indicating that the data is received at the mobile device, transmitting the queued data from the host service to the wireless router for delivery to the mobile device.
