  Method and Apparatus to provide individually customizable (location-based) internet services and content to a number of wireless hotspots using a centralized hosting server.

1 Field of the Invention

The invention being disclosed here relates to wireless hotspots, and more particularly, to the provision of location based services (LBS) to wireless hotspots. LBS includes the delivery and provisioning of location based content and/or location based applications.

1.1 Terminology

Wireless Hotspots are areas ("lochspots"hich) that provide local wireless connectivity (e.g., using WLAN (IEEE 802.11) or Bluetooth technology, but not limited to these). A Location specific application (LSA) is an LBA that has specific business value owing to its being attuned to the specific business processes of the hotspot itself. E.g., in a Caf´ e, the menu and the ordering application are LSA's. Owing to the location-specialization, it is highly possible that such an LSA has probably no value or relevance in a different location - e.g., in a metro train station.

2 Key Advantages of the disclosed method

・The disclosed method can work with standard, off-shelf client devices such as PDAs, and with standard web browser software.

・The disclosed method works with standard, off-shelf Access Points.

・Total hardware and operational costs are lower with central hosting of LBS, for non-trivial numbers of hotspots (e.g., tens of hotspots and beyond).

・On the server side, logical location can be directly inferred from the identification of the Access Point, without the need to map from physical location to logical location.

3 State of the Art - Technical Description

Here we provide some background information about relevant other, state of the art, architectures that address essentially the same problem space. The goal is to show their limitations and to demonstrate the superiority of our method by means of the improvements it brings and the advantages it offers.

LBS architectures that relate to cellular positioning (e.g. mobile telephone environment) are consciously not discussed in this section, owing to their limited relevance to our problem scope.

3.1 Non-centralized approach involving enhanced Access Point/Adjunct Processor

This is the basic method, shown in Fig. 1. In this method, an enhanced Access Point is used, or the Access Point is combined with an Adjunct Processor. As a result, the Access-Point-Complex (dashed box in the figure) is able to function not only as an Access-Point, but also as a location-specific Application and content server (LBA server). No central server is involved. The hardware and operational cost of this type of solution does not allow it to economically scale beyond a few access points. These limitations of the basic approach encourage the development of central server based LBS approaches discussed next.
