Abstract
Abstract A system is disclosed for maintaining processing continuity in a network having a network accessible application and an intermittently connected wireless mobile unit. A transceiver is connected to the network for wireless communication with the mobile unit, and a gateway connected to the network is used to control the transceiver. A stationary processor is connected to the gateway and configured to support access to the network accessible application, which can run either on the stationary processor itself or on a remote processor. Use of network accessible applications from the mobile unit is mediated by an agent dedicated to communication and processing control of the mobile unit. The agent runs on the stationary processor and is connected to the gateway for handling communications between the mobile unit and the network accessible application. To ensure processing continuity, the agent is configured to hold data received from the network accessible application for transmission to the mobile unit only when the mobile unit is in wireless communication with the network.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
158 words
A system for maintaining processing continuity in a network having a network accessible application and a mobile unit intermittently connected through wireless links to the network, the system comprising a mobile unit having a mobile transceiver for wireless communication with the network, a stationary transceiver connected to the network for wireless communication with the mobile unit, a gateway for controlling the stationary transceiver, the gateway being connected to the network, a stationary processor connected to the gateway and configured to support access to the network accessible application from the mobile unit, and an agent dedicated to communication and processing control of the mobile unit, the agent running on the stationary processor and connected to the gateway for handling communications between the mobile unit and the network accessible application, with the agent configured to hold data received from the network accessible application for transmission to the mobile unit when the mobile unit is in wireless communication with the network.
Claim 2
Independent Claim
158 words
A system for maintaining processing continuity in a network having a network accessible application and a mobile unit intermittently connected through wireless links to the network, the system comprising a mobile unit having a mobile transceiver for wireless communication with the network, a stationary transceiver connected to the network for wireless communication with the mobile unit, a gateway for controlling the stationary transceiver, the gateway being connected to the network, a stationary processor connected to the gateway and configured to support access to the network accessible application from the mobile unit, and an agent dedicated to communication and processing control of the mobile unit, the agent running on the stationary processor and connected to the gateway for handling communications between the mobile unit and the network accessible application, with the agent configured to hold data received from the network accessible application for transmission to the mobile unit when the mobile unit is in wireless communication with the network.
Claim 3
Dependent Claim
18 words
The system of claim 1, wherein the stationary processor runs both the network accessible application and the agent.
Claim 4
Dependent Claim
29 words
The system of claim 1, wherein the stationary processor runs the agent and is connected by the network to a second stationary processor that runs the network accessible application.
Claim 5
Dependent Claim
25 words
The system of claim 1, wherein the agent further comprises a module for preventing communication between an unauthorized network accessible application and the mobile unit.
Claim 6
Dependent Claim
27 words
The system of claim 1, wherein the agent further comprises a module for scheduling communication access between a plurality of network accessible applications and the mobile unit.
Claim 7
Dependent Claim
28 words
The system of claim 1, wherein the agent further comprises a module for resolving contentious access requests between a plurality of network accessible applications and the mobile unit.
Claim 8
Independent Claim
150 words
A method for maintaining processing continuity in a network having a network accessible application and a mobile unit intermittently connected through wireless links to the network, the method comprising the steps of maintaining at least intermittent communication between a gateway connected to the network and a mobile unit having a transceiver for wireless communication with the gateway, providing a stationary processor connected to the gateway and configured to support access to the network accessible application from the mobile unit, and running an agent on the stationary processor, the agent being dedicated to communication and processing control of the mobile unit, with the agent connected to the gateway for handling communications between the mobile unit and the network accessible application, and the agent being configured to hold data received from the network accessible application for transmission to the mobile unit when the mobile unit is in wireless communication with the network.
