Definitions
- the invention relates to a method and a communication system for providing geographic information when retrieving information in the WWW or in the WAP-capable service
- the World Wide Web is a communication network that enables information to be retrieved via the Internet using an Internet protocol, in particular HTTP (Hyper Text Transfer Protocol).
- HTTP Hyper Text Transfer Protocol
- the information requested by a user is identified by an address, a so-called URL (Unified Resource Locator).
- the URL has the form "http: // www. Server-name. Domain / pathname / datemame .html" and is sent to the responsible HTTP server in a request message when the information is requested at this address ,
- the URL of a document describes the location and also the storage address where the document is stored. This location may be dependent on the geographic location for which the information provided is intended. On a server 'www.muenchen.de' you will get information about offers in the city of Kunststoff. This geographical connection between the server name and the location for which the information is intended is not defined in the Internet specifications, but is purely coincidental and at most a result of conventions on the WWW. In the case of multiple locations of the same name, only one of these locations receives the URL, in particular the location that first applies for it, in accordance with the current allocation conventions. For this reason, the geographical information available so far is mostly arbitrary and random.
- a higher quality of the information with a geographical reference eg the questions as to which restaurants are close to the current location or a destination or where the next hotel is, can only be obtained when the information request provides specific information about the desired geographical location Position are given.
- This information can then be evaluated by the responsible web server in order to sort and select the available information.
- this is also only possible to a limited extent, since information about a particular municipality can be requested without any problems, but the names of those who are interested are often not aware of the names of neighboring municipalities that may also be of interest.
- the web content could be prepared in such a way that the participant or user enters his position in front of a request on an electronic form that the responsible web server provides and evaluates.
- Various protocol elements are discussed for the treatment of geographically dependent information.
- the extension of HTML documents with a special header or a special META TAG is discussed, with which a geographical reference can be specified in the network or web document.
- This header can be speaking search engines can be used to serve the information seeker with the desired geographically relevant information.
- a corresponding extension of the HTTP header is discussed, in which corresponding geographic information can also be given for a request.
- a network or web client requests information relating to the location from a network or web server via a communication link, in particular a radio communication link, and receives a response back.
- the response from the web server is location-related.
- geographically dependent information can be stored in the server in the classic client-server configuration with communication between the requesting party (client) and the server and queried from there by the client.
- a client transmits from its own web browser in the HTTP header together with the desired URL also the desired geographical position, which the web server uses in order to use the available number of available documents or information to those with the greatest geographical proximity pick out.
- a geographic position of the requesting party which may be automatically determined in the Internet access network, must preferably be transmitted from the access or access network to the requesting subscriber via a further method, in order to be integrated there in the HTTP request in the web browser.
- Such conditions of an access network prevail e.g. m
- a GSM mobile network in which the geographic position of the subscriber is available in the home location register HLR (Home Location Register), but there is no possibility of automatically forwarding this information to the subscriber.
- HLR Home Location Register
- the geographically dependent provision of information is currently being discussed and planned in the WAP environment.
- the information in the home register about the location of the subscriber is to be made accessible to the information providers via a special location or location server, as is sketched in FIG. 2. Since the geographic information is not implicitly transmitted with every information call, but is made available to the information provider or the location server from a third party, a relationship between the information request and the geographic location of the requester is required, which in the WAP environment is determined by the identity of the participant is formed. Since access to the network operator's user database is necessary for the WAP through the use of a special location server, the providers can only use one Provide geographically dependent information offers with a special contract with the network operator. Due to data protection problems, open access to the location server is not possible.
- the invention has for its object to provide an improved method and an improved communication system for providing geographic information when retrieving information in a communication network, e.g. the WWW or in the WAP service.
- a communication network e.g. the WWW or in the WAP service.
- a simple method for requesting position-related data from a network server is proposed by routing the information request of a data end device via an intermediate station and by supplementing the information request with geographical information or location information in the intermediate station.
- Using a special network access computer or web proxy server as an intermediate station enables the system to be easily implemented with little effort, since the many existing data end devices did not have to be reprogrammed and / or converted.
- the intermediary station when completing the information request to make the geographic location information anonymous for the sender in relation to the information-providing station offers the operator of the communication network the advantage of making a central adjustment to the legal regulations regarding the forwarding of subscriber-related data to be able to.
- Establishing the communication connection via a radio connection of a radio interface of a packet-oriented radio communication network in particular enables subsequent use in existing mobile radio systems.
- the WAP standard of GSM, UMTS mobile radio systems or future radio communication systems can be used for information exchange.
- a client-server implementation can be implemented in a simple manner. It can also be used in the WAP environment without any problems.
- the location information added to the intermediate station can advantageously relate to the geographical location of the intermediate station, the geographical location of the data end. ⁇ chtung, a registration location of the data termination and / or the geographical location of the information providing station.
- Fig. 1 shows a known information request by a
- Network client with a network server that delivers this information directly with location reference
- Fig. 2 shows a known information request by a network client to a network server that provides this information with location information that is requested by the network server from a separate location server, and
- FIG. 3 shows a location-dependent information request from a network client at a network server, this being done via an intermediary proxy server.
- a network customer or web client has established a communication connection V with a communication network via its data end device 1.
- the communication network is a packet-oriented radio communication network by the customer, the communication connection being established via a radio connection V of a radio interface.
- Such communication connections are currently known in particular from the so-called WAP (Wireless Application Protocol), which is set up in GSM mobile radio systems as an interface to the Internet.
- WAP Wireless Application Protocol
- the data end device 1 can therefore preferably be a mobile radio station of this or future standards.
- the sketched request from the network customer's data end device 1 for information that can be supplied by a network or web server 3 is directly connected to a local question linked or indirectly linked to a location request depending on the information data.
- the web server 3 supplies information which is also referred to below as location-dependent information data 4.
- the communication connection between the data end device 1 and the network server 3 is not established directly but via a special network or web proxy server 5.
- This web proxy server 5 is interposed at a central point between the data end device 1 of the web client or subscriber and the web server 3.
- Web proxy servers are currently known on their own and are widely used in the currently widespread WWW (World Wide Web) as network access computers in order to reduce the network load. They are used to automatically cache files locally and to remove them from the local memory when they are called up again and not to retransmit them via the Internet. They are also used to enable participants from a private IP address range (IP: Internet Protocol) to access the public WWW, which is done in connection with network address translation.
- IP Internet Protocol
- This geographic location-dependent request 6 is forwarded directly or indirectly to the responsible network server 3 by the web proxy server 5 and processed there accordingly.
- the information returned by the network server 3 to the data end device 1 of the web client is accordingly geographically local dependent information data 4. If there is no location-dependent information data 4 under the requested URL, normal information is sent.
- the data transmission from the network server 3 to the data end device 1 can take place directly or, as shown, via the interposed web proxy server 5.
- a web proxy server 5 represents a central network element in the Internet access network, not all participants have to change their data transmission devices 1 to a new network access program or system, which is generally referred to as a web browser. but can continue to use their usual browser.
- the extensions for the transmission and evaluation of the geographical location only need to be installed at the central points, here the web proxy server 5 and the web server 3. These make up only a fraction of the number of installed web browsers and are also professionally supervised, so that a changeover can be carried out there easily and professionally.
- the software can therefore be updated at these central points without any problems.
- the web proxy server 5 If the geographic location is made available via a separate interface - here the web proxy server 5 - the identity of the subscriber is visible to the provider or the operator of the network server 3, the normal function of a web proxy Servers 5 m connection with the so-called NAT functionality, which converts and anonymizes all HTTP requests to a common IP address, obscuring the identity of the requesting party. If, in addition, a "geo-location" web proxy server without NAT function and a normal web proxy server 5 with NAT function are provided, the subscriber has it all by entering the corresponding proxy server in the browser his data end device 1 under control, how far he wanted to use the location information and how far he wanted to reveal his identity.
- the network operator no longer needs a special interface for forwarding the geographical location to service providers, since it transmits the information directly to the requests or HTTP requests.
- the organizational and technical effort for the provision of the geographical location on the WWW is correspondingly minimal.
- the communication network is dialed in via a landline network
- dialing in ms Internet is currently usually carried out in the same area of the local network for cost reasons, i.e. at a geographically close geographic position.
- a geo-location web proxy 5 or location network access computer is installed there, which permanently incorporates its own geographic position m the HTTP requests, the information transmitted is correct for most network customers without special precautions for user-dependent Determination of the geographical position had to be made.
