Abstract

A fixed wireless network is defined by a home gateway (102) communicating with a network interface device (108) located in vehicles within a fixed predefined area (112). The network interface devices enable the transfer of vehicle location related measurements to the home gateway (102) when the vehicle is within the fixed predefined area (112). When the vehicle roams outside the predefined area (112), measurements are obtained by an in-vehicle Global Positioning System (GPS) (106) and stored in logging database (110). The obtained measurements are then uploaded from the logging database (110) to the home gateway (102) using the network interface devices when the vehicle returns to the fixed predefined area (112). The measurements can further be uploaded from the home gateway to a network-based service location system (105). The measurement may include maintenance, speed, or vehicle usage information.

TECHNICAL FIELD The present invention relates generally to the field of wireless communications. More specifically, the present invention is related to electronic record keeping.
BACKGROUND ART One popular method of implementing a wireless connection is based upon the IEEE 802.11 standard. 802.11 refers to a family of specifications developed by the Institute of Electrical and Electronics Engineers (IEEE) for wireless local area network
(LAN) technology. 802.11 specifies an over-the-air interface between a wireless client and a base station or between two wireless clients. There are several specifications in the 802.11 family, some of which are described below:
• 802.11 - applies to wireless LANs providing 1 or 2 Mbps transmission in the 2.4 GHz band using either frequency hopping spread spectrum (FHSS) or direct sequence spread spectrum (DSSS).
• 802.11a - an extension to 802.11 that applies to wireless local area networks (LANs) and provides up to 54 Mbps in the 5 GHz band. 802.11a uses an orthogonal frequency division multiplexing encoding scheme rather than FHSS or DSSS.
• 802.11b - also referred to as 802.11 High rate or Wi-Fi (for wireless fidelity), formed as a ratification to the original 802.11 standard, allowing wireless functionality comparable to the Ethernet. This is an extension to 802.11 that applies to wireless LANs and provides 11 Mbps transmission (with fallback to 5.5, 2, and 1 Mbps) in the 2.4 GHz band. Transmission in the 802.1 lb standard is accomplished via DSSS.
• 802.1 lg - applies to wireless LANs and provides 20+ Mbps in the 2.4 GHz band.
The most popular of the above standards is the 802.1 lb.

DISCLOSURE OF THE INVENTION The present invention provides for a network-based home vehicular management system (located within a vehicle), wherein the system comprises a global positioning system (GPS) for identifying location information, a data logger that is operatively linked with the GPS, and a wireless network interface capable of communicating with at least one gateway via a protocol such as the IEEE 802.11b protocol. The data logger periodically collects and stores location information when the home vehicular management system is outside of a fixed wireless network coverage area. The wireless network interface is capable of transmitting the stored location information to the gateway, wherein the transmission is triggered when the home vehicular management system is within the fixed wireless network coverage area. The gateway forwards the location information to a network-based service location, and the service location utilizes the received location infonnation to offer various historical vehicular position services.
The historical vehicular position services offered by the service location comprises any of (but should not be limited to) the following: notifications regarding maximum speed exceptions, notifications regarding acceptable routes or destinations, notifications of preventive maintenance, or tax oriented record keeping services.
Additionally, communications between the gateway and the network-based service location are envisioned to be performed over any of the following networks: local area network (LAN), wide area network (WAN), wireless network, or the Internet.
The present invention also provides for a method for receiving historical vehicular position services, wherein the method comprises the steps of: (a) identifying when a vehicle enters a fixed network coverage area, wherein the vehicle is equipped with a global positioning system (GPS) for identifying location information, a logging system for periodically collecting and storing location information, and a wireless network interface for communicating via a protocol such as the IEEE 802.1 lb protocol;
(b) establishing a wireless communication link with a network interface when the vehicle is within the fixed network coverage area; (c) wirelessly receiving the stored location information; (d) forwarding the wirelessly received location information to a service location over a network, the service location identifying historical vehicular position services based upon the received location information; and (e) receiving the identified historical vehicular position services. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 illustrates a general architecture of the preferred embodiment of the present invention. Figure 2 illustrates a method associated with the preferred embodiment of the present invention.
BEST MODE FOR CARRYING OUT INVENTION While this invention is illustrated and described in a preferred embodiment, the invention may be produced in many different configurations. There is depicted in the drawings, and will herein be described in detail, a preferred embodiment of the invention, with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and the associated functional specifications for its construction and is not intended to limit the invention to the embodiment illustrated. Those skilled in the art will envision many other possible variations within the scope of the present invention.
Figure 1 illustrates the general architecture of the present invention, wherein the architecture comprises a home wireless home gateway device 102 in communication with a vehicle-based system 104, and a network based service location 105. The vehicle-based system further comprises a Global Positioning System (GPS) 106, a wireless network interface 108 (compatible with the home gateway device 102), and a logging system 110 capable of collecting and uploading GPS position information. The area enclosed by 112 defines (simply for the purposes of this example) the network coverage area within which the home gateway device 102 is able to communicate wirelessly with the network interface 108 of the vehicle-based system 104.
One scenario involves a vehicle that is initially located within the fixed network coverage area 112, but is departing that area. While outside the coverage area 112, the
GPS 106 and logging system 110 within the vehicle collects and stores periodic time and location information, a function commonly available in GPS systems. When the vehicle is within the fixed wireless network coverage area 112, wireless network connectivity is established (between the home gateway 102 and vehicle-based device 104), via a protocol such as the IEEE 802.11b protocol, and the vehicle's stored route information (stored in logging system 110) is uploaded via the home gateway 102 and it's associated public network connectivity (e.g., dial-up or broadband) into the network-based service location 105.
Once the route information is available at the network-based service location
105, historical vehicular position services may be offered to the home gateway subscriber. These services could include (but are not limited to) notifications regarding vehicle usage, such as maximum speed exceptions, acceptable route, destination exception, or a simple record of routes and destinations. Additional vehicular mileage- based services envisioned include (but are not limited to): notification of required preventive maintenance, tax oriented record keeping services, or in conjunction with an additional subscriber input regarding trip purposes. It is also envisioned that the disclosed invention can be used in record keeping (such maintenance is done in prior art using paper records) for providing an electronic means for reviewing the travel. Figure 2 illustrates a method 200 associated with the preferred embodiment of the present invention. In step 202, an identification is made when a vehicle enters a fixed network coverage area (i.e., 112 of Figure 1). The vehicle, as in Figure 1, is equipped with a GPS unit for identifying location information, a logging system for periodically collecting and storing location information, and a wireless network interface for communicating via a wireless protocol such as the IEEE 802.11b protocol.
In step 204, when the vehicle is within the fixed network coverage area, a wireless communication link is established between the gateway and the wireless network interface. In step 206, location information stored in the logging system is received wirelessly by the gateway, which, in step 208, forwards the location information to a service location over a network. The service location identifies historical vehicular position services based upon the received location information. Finally, in step 210, historical vehicular position services are received by a computing device operatively linked with the gateway.
CONCLUSION A system and method has been shown in the above embodiments for the effective implementation of a network-based home vehicular management. While various preferred embodiments have been shown and described, it will be understood that there is no intent to limit the invention by such disclosure, but rather, it is intended to cover all modifications and alternate constructions falling within the spirit and scope of the invention, as defined in the appended claims. For example, the present invention should not be limited by the type of service offered at the network-based service location, the type of network over which the home gateway and network based service location communicate, specific home gateway hardware, radius of fixed wireless network coverage area, or the type of storage used in the logging system.
The above enhancements are implemented in various networking environments. For example, communications between the home gateway device and the network- based service location may be over various networks, such as: a local area network (LAN), a wide area network (WAN), or the Internet.
