Abstract

A wireless communication system, comprising a host service, a wireless router system coupled to the host service, a wireless network coupling the wireless router system and a wireless mobile communication device (“mobile device”), adaptively delivers data to the mobile device in the wireless communication system using a notification message delivery mechanism. Mobile device reports its session state to the wireless router at a regular interval or if there is a change in state. The host service sends out a message to the wireless router to query the state of the mobile device. If the state of the mobile device is determined to be in coverage (or logged on), the host service sends down the data message to the mobile device using a payload message (MTH) with certain parameters configured. The data is temporarily stored at the wireless router. If the device is available, the message is sent to the device over the wireless network. If the device is not available, the wireless router returns the payload message back to the host service, updating the status of the device. The wireless router also reports to the host service any change in device state. If the device is back in coverage, the payload message is then resent from the host service to the device.

Claims

1. A method of data message delivery from a host service to a wireless mobile device using a wireless router, the mobile device having a status, comprising the steps of:

sending a data message from said host service to said wireless router when the device status as indicated to said host service is “

available”

, wherein said data message further comprises one or more request parameters;

delivering said data message to said mobile device when the device status as indicated to said wireless router is “

available”

; and

receiving at least a portion of said data message at said host service when said device status is “

unavailable”

as indicated to said router, wherein said at least data message portion further comprises a response to said one or more request parameters.

2. The method of claim 1 wherein said one or more request parameters comprises a request for device status as indicated to said router, and the response is the device status as indicated to said router.

3. The method of claim 2 wherein if said response indicates said device status is “

unavailable”

as indicated to said router, said method further comprising re-sending the data message from said host service to said router when the device status as indicated to said host service is “

available”

.

4. The method of claim 1 wherein said request parameters consists of a “

data_return” and

a “

status_request”

parameter.

5. The method of claim 4 wherein said request parameters are configurable.
