DE102020006381A1 - Process for the transmission and storage of web content and for locating a digital end device via the BSSID MAC address of an access point and additionally in connection with a public IP address without a WLAN connection to the access point and/or the Internet having to exist - Google Patents

Abstract

This invention describes a method and a device that stores the transmission of WEB content at a specific point in a WLAN network in encrypted form on a storage medium and makes it temporarily or permanently available to the device / terminal device at this specific point without a direct connection to this WLAN puts. At the time the web content is broadcast via a classic transmission medium, the content stored locally on the end device is activated using a time and event-controlled key and can be viewed by the user at the same time as it is being broadcast via classic transmission channels. It is completely transparent for a user whether he is using a Looks at web content that is currently being broadcast or looks at web content that is stored locally on his end device. The method described can only be applied to previously saved web content at the locally stored points of a WLAN (BSSID, distance to various access points) and thus covers the majority of the broadcast web content. Real live content is transmitted to a local, general storage medium via a narrow-band transmission channel near the receiving device and from there it is duplicated via a transmission unit and distributed to the end devices. The advantage of this method over the prior art is that information can then be played out , even if there is no or only a limited connection between the transmitter and receiver or there is no Internet connectivity. Applications of this method can be found where several people in a limited location want to use content at the same time via a network, but this would fail due to a low transmission rate. Examples are ships, planes, trains and buses. An additional area of application are indoor areas without direct access to a generally accessible GPS signal, in order to be able to play out context-sensitive information at specific points and also to enable indoor navigation at specific points within a single SSID based on the distance calculation to BSSID (access points). Examples are train stations, basements, metro stations. PRIOR ART Web content and information are generally played out today via Internet connectivity globally in an SSID (name of the WLAN network) or a router (IP_address ranch). This transmission path / type of transmission is referred to as classic in the following. The storage of web content is a standard procedure that enables the user to find and view web content at a later point in time. The content or the web address is stored on a hard drive. During playback, the end device reconnects to the Internet and the content is transmitted again via the classic transmission path. An SSID is a network name that is displayed on a router as a WLAN for end devices. It can be visible or broadcast as hidden, which is then only recognized by known end devices. It suggests internet access for the user. An SSID consists of 1 + N BSSID. A BSSID is the MAC address of an access point in the respective radio band (as of today: 2.5 GHz and 5 GHz). A BSSID Mac address can be seen by an end device without being connected to this WLAN.

Description

In many cases, e.g. planes, ships, trains, buses, train stations, metro, airports, supermarkets, etc., it is not possible to display the location and to provide internet with sufficient bandwidth.

On the subject of Internet bandwidth: Even if there were enough bandwidth for the individual user, it would no longer be sufficient for everyone if it was used multiple times.

On the subject of location: On the one hand, it is due to the fact that mobile transport devices are moving and cannot be clearly assigned, on the other hand, they are outside an area such as e.g. in the basement or shielded by roofs from an available GPS navigation signal. In the case of moving transport facilities, the user does not want to be informed again and again with the constantly changing GPS signals, but is instead focused on data relating to the transport medium, such as train/flight information, car number, seat, restaurant information, etc. In closed buildings, the information is only available connected WLAN network can be seen over the entire area.

The configuration on which the invention is based consists of a combination of several data sources that are independent of one another. At the beginning, the end device saves the last available GPS signal information data from a local or cloud-based backend on an internal storage medium, consisting of the available BSSID in the area, saved information on the individual BSSID (Mac address, position data and web content), available SSID's in the vicinity.

As soon as an SSID (WLAN network) is only seen by the end device, the information (web content) from the storage medium is displayed via push notification or can be called up manually. It is not relevant for the user whether there is a connection to the Internet via WLAN or mobile radio or whether he is "offline" at this point. There is an INDOOR navigation from BSSID (access point) to BSSID (access point) without internet access, GPS signal and without being connected to a WLAN itself. The accuracy is in the range of approx. 20cm. The position data is stored once in advance in the cloud-based or local backend.

It is irrelevant which end device / manufacturer the user uses, only a WLAN module has to be installed.

example

When a location is first integrated, all BSSIDs (access points) are recorded with special software (application on a manufacturer-independent device) and with a location stamp (various attributes such as GPS data, location, peculiarities (e.g. meat counter, dining car, car number, seat, etc.) and connected to an SSID (name of the WiFi network) in the backend (cloud server) in a list.

If another end device with this application comes close to this WLAN SSID, the end device recognizes the location and transmits the information stored there by means of a PUSH notification or shows the information manually on the screen of the end device without having connected to this WLAN and internet is available. If you now want to reach a certain point, you will be guided from point to point to the Zil without having to have a connection to the WLAN / Internet. The distance is measured using the signal strength in cm.

In this specific case: You are standing in front of a supermarket and you get a message saying “Welcome to our supermarket on Musterstrasse, Musterort. The user now sees a map of the building and taps on a desired POI (Point of Interest), the special application guides the end device to this POI using the BSSID and stored information without having to be connected to the Internet or WLAN, or GPS data available.

claim

1. A. Transmission of information / web content via a classic transmission path such as the Internet or a local server within an SSID (WLAN network) context-sensitively related to an access point or at a specific location point within this network for live viewing by the user
2. B. Transmission of information / web content via a classic transmission path such as the Internet for the purpose of storage on a local hard drive or a cloud-based hard drive context-sensitively related to an access point or at a specific location point within this network
3. C. Transmission of BSSID data (MAC address of the access point) via a classic transmission path such as mobile Internet or WLAN Internet for the purpose of storage on a local hard drive or a cloud-based hard drive, decisively according to what can be reached GPS signal related to a specific location point within this network
4. D. Offline transmission of information / web content with a WLAN connection, but without Internet and without a connection to a local server / cloud-based storage, context-sensitive to a specific SSID (WLAN network) or to a specific location within this WLAN network
5. E. Offline transmission of information / web content without a WLAN connection and without the Internet and without a connection to a local server / cloud-based storage, context-sensitive to a specific SSID (WLAN network) or to a specific location point within this WLAN network

These 5 possibilities have different advantages and disadvantages, whereby the system according to the invention weighs these advantages and disadvantages against each other when making the choice. If not all transmission paths A to E are available, the system according to the invention will select the most sensible, technically feasible and economically most favorable transmission path for the user.

The costs for method A are independent of the number of users. This is advantageous when there are large numbers of users, while the costs for providing a transmission path are high.

Method B allows storing a lot of information and web content on one storage at the same time. There is no need to repeatedly save the same information and web content and it is then available locally without traditional transmissions via the Internet

Method C enables the one-off storage of a large number of BBSID data and the associated GPS data that would normally be requested several times by many users, thus saving costs and time for transmission in the classic sense via the Internet and mobile phones

Method D enables the transmission of different information / web content in a context-sensitive manner at a certain point without actually being connected to the Internet within a connected WLAN network, however, without a GPS signal, navigation within this WLAN network is also possible. It is suitable for indoor locations where there are many people within a network, as it saves resources and is free of charge when transferring data.

Method E enables the transmission of different information / web content context-sensitive at a certain point without actually being connected to the Internet and also not to a connected WLAN network and navigation within this WLAN antenna signal is also possible without a GPS signal. It is a pure OFFLINE version and is suitable for places with a lot of people in a small space such as stadiums, trains, train stations, large company premises / buildings, etc. This method is free of charge in the transmission of data and navigation and comes without internet and mobile communications and therefore does not burden any transmission paths.

Web content / information is stored in the storage areas of the local or cloud-based storage allocated for the WLAN infrastructure owner. These areas can be managed by the WLAN infrastructure owner according to customer requirements or according to their own ideas.

Web content / information that is not released at the time of storage, for example because it has not yet been broadcast in the running web interface, is stored in encrypted form. The decryption key is managed by the WLAN infrastructure owner.

A major advantage of the system according to the invention is that the web content/information can be transmitted to the users via a number of transmission paths, with the most favorable transmission path being used in each case. The choice of transmission path is transparent for the user. The user can view the content stored on his own end device at any time, provided that it has been activated by the WLAN infrastructure owner.

The normal web content / information can be separated from personalized advertising / information in the system and method according to the invention, with the normal web content / information being transmitted via a classic transmission path, while the personalized advertising / information is transmitted and stored via the local network / cloud-based storage medium. Advertising would therefore not have to be broadcast live, but could be broadcast in advance and then superimposed on the normal signal using various overlay mechanisms. The switchover can be controlled by a signal provided by the WLAN infrastructure owner or, for example, sent by a triggering event (at a certain point).

In the same way, web content / information that is only viewed by a few users can be transmitted over the Internet while Web content / information that reaches a large number of users is sent to the user via local transmission. The advantage of this method is that no expensive Internet upload server channel has to be used for web content/information that only reaches a few viewers. As soon as the number of users exceeds a predetermined threshold, it is possible according to the invention to switch from the Internet to a local transmission path even during a transmission.

If a direct connection channel is established between the local server and a WLAN-enabled end device, the web content/information can be viewed on it.
