Description

A wireless communication terminal for accessing location information from a server}

There are many ways to determine the locations. For example, the location of the car can be determined by a so-called car navigation system. Navigation systems of this kind may include satellite receivers and mobile telephones connected to processing means. The satellite receiver, for example a global position system (GPS) receiver, may receive signals indicating the position of the receiver, in this case the car. The received signals can then be processed by the processing means and sent to the server as a request by the mobile phone. The server may be provided with a location database comprising, for example, digitized maps, the server may respond to the request. The response can then be processed by the processing means, for example shown on the display as a digitized map. In this way, it will be possible to obtain position information depending on the position of the car.

One example of a navigation system is known from WO96 / 11381 which describes a navigation device for people. The device comprises a navigation unit having a receiver device for wireless transmission of data for detecting a current geographical position. In particular, it is possible to provide an input unit for input of the target position. The result of this input is in particular presented by an output unit for the output of route guidance data. In order to process all the data, the device further comprises a computer, in particular for route planning. The computer includes a memory having a digitized road map and can be connected to the navigation unit via a communication unit for data transmission. The navigation unit, the communication unit, the input unit and the output unit form a portable hardware unit. The communication unit comprises a transmitter-receiver for wireless transmission of route data between the computer and the portable unit.

Another example of a navigation system is disclosed in WO 96/07110. This describes a navigation information system including a communication system having a fixed part and a moving part. The fixing portion includes data storage and processing means, the processing means identifying the position of the mobile unit, generating guide information suitable for the position, and transmitting the information to the mobile unit. The user requests guidance information, and the system determines the current location of the user and then sends a command to the user. The current location of the user may be determined by means such as a satellite positioning system.

An alternative method of measuring position in the navigation system by satellite receivers is shown for example in EP-A2-0753978. It describes the process and processor controlled station control that directs a subscriber towards a destination within a Space Division Multiple Access (SDMA) mobile wireless network. The station control includes a communication interface unit and a microprocessor. The communication interface unit receives a message specifying a destination desired by the subscriber. The microprocessor determines the current location of the subscriber by calculating direction and distance information. The station control further includes a communication interface unit. By the communication interface unit the station control retrieves information from a database and establishes a route from the location to the destination. This information is transmitted in a simplified format to the subscriber's mobile wireless terminal.

However, all such navigation systems described above all depend on the location of the user. This means that a user requesting a service, for example traffic information request, from a service provider must include his current location. This is a serious disadvantage. This is because in some cases this requires an additional device that can be more expensive. Moreover, the user must convert the location information into a predetermined format and send the location information along with the service request to the server. This approach is difficult to collaborate with other service providers who may require different types of formats.

In addition, even a user using a cellular location process as disclosed in EP-A2-0753978, this requires the user to disclose his actual location to the service provider. This means that the user must reveal his or her location, which is a significant security risk if the user is not sure of the credit of the service provider. For example, if the request is processed at the server, the hacker can more easily find out where you are, or worse, include the virus in the response returned to the terminal. In addition, when transmitting the actual location of the user, it will take up a lot of space in the traffic on the wireless network. This is because data transmissions on a wireless network usually have very narrow bandwidths.

Moreover, WO99 / 27742 discloses a telecommunication system, which uses a terminal-based browser in a mobile phone to connect a telephone to web-based location services and a mobile positioning center (MPC). The browser may present graphical information, which allows the user of the mobile phone to determine the current location of the mobile phone. The browser may also communicate with a location service node via a cellular network. To obtain the current location of the phone, the browser first sends a location request and format information associated with the location request to the location service node. The MPC then receives the request from the location service node and determines the telephone coordinate location. Information about the location of the phone is then passed back to the phone and displayed above the browser. However, as disclosed in EP-A2-0753978, this requires the user to disclose his actual location to the service provider, which means that the user must reveal his location and is a significant security risk. .

The present invention relates to a method, terminal and system for providing location information from a server to a wireless communication terminal.

5A and 5B show an example of a user interface in a telephone in accordance with the present invention.

Thus, there is an important need for wireless communication terminals to receive location information from servers more efficiently and to have an increased level of security. It would also be advantageous to avoid the transmission of unnecessary location information. Another need is to have a single format for location information independent of the format requested by the service provider to facilitate the use of different location tools.

In accordance with an aspect of the present invention there is provided a wireless communication terminal for accessing location information from a server. The terminal includes a receiver and a transmitter destined to receive data packets from at least one server and destined to transmit data packets to the at least one server. The at least one server comprises a location means connected to the link means via a wireless communication network. The link means is arranged to forward the data packets between the terminal and the server. Memory is also provided to the terminal, the memory comprising at least one item, the item being provided with an access point indicating the site of the server to be accessed. The server is accessed by sending a request to the link means for accessing and receiving content from the server as a data packet comprising the access point via the wireless communication network. A browser application is arranged to establish a session with the linking means by reading the item from the memory in the terminal. Enable the transmitter to transmit the request as a data packet to the server via the link means, and process the content received by the receiver. The user interface connected to the browser application includes display means for displaying content received from the server and user input means for providing input to the browser application. The input includes an inquiry of location information independent of the location of the terminal. The input is provided in the request and is arranged to receive, by the location means, content including an indication of the location information from the server.

Thus, the basic idea of the present invention is to provide a request from a wireless communication terminal, such as a cellular telephone, to access location information from a server that contains location information independent of the location of the terminal. This means that the terminal sends a request to the server to receive an indication of location information without revealing the location of the terminal when sending the request to the server. By way of example, the invention may be implemented in a Wireless Application Protocol (WAP) architecture environment. Wireless Application Protocol (WAP) is the result of ongoing work to set industry-wide standards for developing applications on cellular communications networks. This makes it possible to access other types of information networks, for example the Internet or hypermedia servers, provided from ordinary cellular telephones supporting WAP. Cellular phones of this type supporting WAP have only a fraction of the resources of a typical desktop or portable computer. This means that the features of the phone are very limited compared to a computer. The reason for this limitation is the size of the phones. That is, the phone has strict limitations on processing power, memory space, display size and buttons or keys that allow the user to request, view and manipulate information obtained from the hypermedia server. Therefore, it is very important that the features of the telephone are as efficient as possible. In addition, it is also very important to provide a quick response from the server to the customer since calling from a cellular telephone is relatively expensive.

A particularly preferred embodiment is that the terminal can also be provided with a location means. The location means determines the location information of the terminal and sends the location information to the server when there is a request from the server or upon request sent to the server to provide an indication of the location of the terminal. Send selectively Thus, because it is optional, it is the user who controls the information sent between the terminal and the server. This would also provide a high degree of freedom for the user to choose between different alternatives by selecting what location information should be sent to the server.

Further advantages according to the invention will be apparent from the dependent claims.

The invention will be explained in more detail below with reference to the accompanying drawings by way of examples only.

1 shows, according to the invention, a preferred embodiment of a wireless communication terminal, also referred to hereinafter as a telephone. The telephone, generally indicated by reference number 1, comprises a user interface with a keypad 2, a display 3, an on / off button 4, a speaker 5 and a microphone 6. The telephone 1 according to a preferred embodiment is suitable for communicating via a wireless telecommunication network, for example a wireless network. However, the telephone can also be designed for a wireless network. The keypad 2 has keys of the first group 7 as alphanumeric keys. The keys of the first group allow the user to enter a phone number, enter a text message (SMS), enter a name (associated with the phone number), and the like. Each of the twelve alphanumeric keys 7 is provided with a number "0-9" or a sign "#" or "*", respectively. In alpha mode each key is associated with a number of characters and special symbols used for text editing. The keypad 2 additionally comprises two softkeys 8, two call manipulation keys 9 and a navigation key 10.

The two softkeys 8 have functions corresponding to functions known from the telephones Nokia2110 ^™ , Nokia8110 ^™ , and Nokia3810 ^™ . The function of the softkeys depends on the state of the phone and the navigation within the menu by the use of the navigation keys. The current function of the softkeys 8 is shown in separate fields in the display 3 directly above the keys 8.

The two call operation keys 9 are used to set up a call or conference call, terminate a call or reject an incoming call.

The navigation key 10 is an up / down key and is located in the front center of the phone between the display 3 and the group of alphanumeric keys 7. This allows the user to control this key by simply pressing the up / down keys using the user's thumb. In other words, this allows the user to scroll between a group of items, for example in a menu provided within the user interface. Since experienced telephone users are accustomed to one-handed control, placing an input key that requires precise motor movements is a very good solution. Thus, the user can place the phone in a hand between the fingertips and the palm of the hand. Thereby, the thumb is free to enter information. In another embodiment, the scroll key may be a roller key (not shown) which is arranged to rotate in one or several directions. The roller allows the user to roll the key to scroll between different items in the menu. In the case of a roller key, the softkey 8 can be arranged on the roller. That is, when the roller is pressed, the same function as that of the operation key may be input. The roller key has a function corresponding to a function known from the telephone Nokia7110 ^™, for example. The phone also supports Wireless Application Protocol (WAP). The roller key is incorporated by reference in US patent application Ser. No. 08 / 923,696.

2 schematically shows the most essential parts of the preferred embodiment of the telephone. These parts are essential for understanding the present invention. While the preferred embodiment of the telephone of the present invention is suitable for use in connection with a GSM network, of course the present invention also provides for such a system or in connection with other telephone networks such as other types of wireless networks and various types of wireless telephone systems. Can be applied in dual band phones accessing sets of networks / networks. The microphone 6 records the voice of the user, and the recorded analog signals are A / D converted by an A / D converter (not shown) and encoded by the audio unit 14. The encoded speech signal is transmitted to the control means 18. The control means 18 comprises a processor capable of supporting software in the telephone. The control means 18 also form an interface to the peripheral units of the device. The peripheral units may include (as well as data, power, etc.) RAM memory 17a and flash ROM memory 17b, SIM card 16, display 3, browser application ( 20) and the keypad 2 may be included. The browser application 20 can be used to request and receive content from a server, as described in more detail below with reference to FIGS. The control means 18 communicates with the transmitter / receiver means 19, which is a circuit suitable for receiving a response from, for example, sending a request to a telecommunications network / telecommunications network. The audio section 14 voice-decodes the signal and the signal is transmitted from the control means 18 to the receiver 5 via a D / A converter (not shown).

The control means 18 is connected to the user interface. Thus it is the control means 18 that monitors the activity in the telephone and controls the display 3 in response thereto. It is therefore the control means 18 to detect the occurrence of a state change event and to change the state of the phone and thus the display text. When the user activates the keypad including the navigation key 10 a state change event may be caused by the user and these types of events may be entry events or user events. It is called However, the network in communication with the telephone can also cause a state change event. This type of event and other events beyond the control of the user are called non user events. Non-user events include state changes, battery voltage changes, antenna state changes, messages upon receipt of SMS, etc. during call setup.

Access location information from server to wireless terminal

3 schematically illustrates a system 301 for accessing location information from a server. The system includes a plurality of web servers 320, 330, and 340 in a wireless communication terminal 300, a wireless network 310, and an internet network 350. The Internet network 350 uses World Wide Web (WWW) protocols, and the Internet network is provided with location means. The location means is arranged to receive data packets from the terminal and to transmit data packets to the terminal. For example, the location means may be a database comprising textual information and / or digitized maps describing the location. In order to send updated location information to the terminal, the database can be updated continuously. The wireless network 310 is arranged to establish a wireless connection 305 between a plurality of wireless terminals 300 and link means 360. Although the link means are usually connected to a server to be accessed, it is also possible that the link means can also be integrated with the server to be accessed.

The terminals 300 may access at least one of the web servers 320 to 340 provided with a location means via the link means 360. The terminals 300 may typically be cellular telephones. In general, the link means 360 is arranged to enable a session for the wireless communication terminal 300 and to transmit data packets between the terminal and one of the web servers 320-340. Thus, the web servers 320-340 are arranged to receive and / or transmit data packets from / to the terminal 300. Delivery of data packets is often referred to as pull and / or push. The pool can be described as the terminal using an access point, for example, to access a site where the location information is stored, and can also determine if the location information has been updated and retrieve the location information if necessary. In some cases, it may also be possible to use push. The push can be described as opposed to the pull, i.e., the server maintains the address data necessary to deliver updated location information to the terminal.

The link means 360 in this example is typically a gateway or proxy, but hereinafter referred to as a gateway. Proxy servers are processes that allow a user to fetch different types of documents, such as WWW, FTP, and GOPHER documents. The proxy server may store the documents in a cache memory in the wireless terminal. This means that if someone retrieves a document other than delivering these files to the wireless terminal, a copy can also be created on the local host. Thus, a request is sent to the remote host to know if the page has been updated the next time the user accesses the document, and if the page is not updated, read the page directly from the cache memory. The gateway may be a computer placed at the intersection of the server and the client to be accessed and routing traffic from one or several servers to the client. Thus, the gateway's function is to provide a link between two different types of electronic communications, such as the WAP architecture and the Internet architecture. The communication between the wireless terminal 300 and the gateway 360 follows a wireless application protocol (WAP).

WAP defines a set of standard protocols that enable communication between wireless communication terminals, such as cellular telephones and network servers. Other types of communication terminals may be pagers and personal digital assistants (PDAs). WAP uses a standard naming model that depends on which standard Internet URLs are used to identify content on different web servers. WAP also uses content typing. All WAP content is given a specific type consistent with WWW typing that allows the wireless terminal to correctly handle content based on type. WAP also uses standard content formats and standard communication protocols. Thus, WAP brings Internet content and enhanced data services to wireless terminals. WAP may work on different wireless network technologies and bearer types (TDMA, CDMA, SMS). Communication between the web servers 320 to 340 and the gateway 360 is in accordance with the WWW protocol.

In this embodiment, the gateway 360 translates, i.e. formats, requests for location information from the WAP protocol stack used by the wireless terminal 300 to the WWW protocol stack used by the web server. The web server leaves a response with an indication of the location information, for example WAP content such as Wireless Markup Language (WML), Wireless Markup Language Script (WMLScript), Extensive Markup Language (XML). And / or WWW content, such as hypertext markup language (HTML). In the latter case, a filter is used to translate, ie, format the WWW content into WAP content, for example HTML into WML, WMLScript or XML. In a preferred embodiment, the gateway can encode content transmitted to the wireless terminal on the wireless network and can decode data transmitted to the gateway by the wireless terminal. This means that the system, i.e., the terminal, the link means and the server, can be provided with encoding / decoding means which can enable rapid transmission of data packets between the server and the terminal. Thus, this enables the delivery of binary data packets that are delivered much easier (faster) than unencoded data packets. One way of processing data packets in binary format is to use the so-called WAP Binary Content Format (WBXML), such as the Wireless Binary eXtended Markup Language (WBXML).

In another preferred embodiment, a security means (not shown) may be provided at the terminal, and the security means may require confirmation of a request sent to the server. The security means may be provided within the browser application and may be a default or optional feature. That is, the user may or may not interact. Thus, when the security means are activated, the user must confirm whether the user wants to send the request to the server. An important reason for having security measures is that in some cases the user reveals his or her location, which in some cases can be dangerous. For example, if you are not sure about the credit of the service provider. This means that if the request is processed at the server, a hacker can more easily find the user's location, or worse, can include a virus in the response returned to the terminal. In addition, when the terminal is connected to a location means, for example a vehicle navigation system, this can reveal the location of the user directly. Thus, the security means can provide any privacy to the user and do not reveal any information to the third party without the user's permission.

In addition, to provide a high level of security when transmitting wireless information, the system may also encrypt / decrypt data packets between the terminal and the server. The data packets include the request, the formatted request, the response and the formatted response. This means that encoders and decoders (not shown) can be provided at the gateway. The server may also include different algorithms for encrypting / decrypting. The encryption / decryption itself may be performed by well known methods, for example RSA, Diffie-Hellman and the like. Regardless of how the location is gathered at the WAP client, i. In addition, the user wants to confirm that his location is available only to the designated origin server and not to other parties. The user's decision as to who the user would like to provide the location information can be realized in many different ways. For example,

1. The user is prompted for all the time that the WML script function is being processed.

2. Manage a list of URLs that point to trusted servers. The URL of the calling WML script can be checked against this list. This URL is known to the terminal by comparing the requested URL with a list of trusted servers. If the URL is reliable, the WML script function is executed. In case of failure, an invalid string may be returned.

3. The client, i.e. the terminal, may request to encrypt with a fixed mechanism in a crypto library whenever there is an output of the script library. The crypto library provides the possibility of signing the client's data and can encrypt the user data before transmission.

4. A server certificate that only identifies the link means can be used. If the WML script is requested from an origin server other than the linking means, the linking means must be careful with the privacy.

Applying the second option to this preferred embodiment means that the client must check the URL of the calling WML script before the script function is executed. The script is processed only if the WML script is requested or pushed from a trusted server, which is listed in a specific location trusted server list. This list can be managed by the user. The crypto library may also be a so-called WML script crypto library that offers the possibility of signing client data with a digital signature before being sent to the origin server. In addition, this library offers the possibility of encrypting the user data before being transmitted.

The wireless application environment that forms the upper layer of the WAP stack also includes a browser application called a microbrowser. Typically, the encoding / decoding means is provided in the browser application of the terminal. The browser may use a lightweight markup language, which is a WML and WMLScript lightweight scripting language. WML implements card and deck metaphors. The browser and user interaction is described as a set of cards that are grouped together in a document, commonly referred to as a deck. The user navigates to a card in the deck to review its contents and then navigates to another card in the same deck or another card in a different deck. The user can also enter the requested information, select it, and move to another card. The decks of cards are forwarded from the origin servers if necessary. Cards are grouped together in decks. Thus, the content received by the user from the server mainly includes cards and decks. WML decks are similar to HyperText Markup Language (HTML) pages in that they are identified by URLs and are units of content transfer. WML includes text and image support, and includes various formatting and lay-out instructions. WML includes support to explicitly manage navigation between cards and decks. WML also supports fixed links similar to anchored links in HTML.

The wireless communication terminal is generally different from a desktop or portable computer with Internet facilities in that it has a less powerful CPU, less memory, limited power consumption, smaller displays and more limited input devices. The wireless network is generally different from the internet network in that it has less bandwidth, more latency, less connection stability and less predictable availability. The WAP architecture is optimized for narrow bandwidth bearers with potentially high latency and for efficient use of device resources.

When communicating with the wireless network 310, for example to receive, access and transmit data packets from the web server 320 via the gateway 360, the wireless communication terminal 300 is a receiver and a transmitter. (19; FIG. 2). The terminal 300 further includes a memory (see SIM card 16 (FIG. 2) and ROM 17b (FIG. 2)) provided with an identifier and at least one item. The item is provided with an access point indicating the location of the server to be accessed, which may be indicated by a Uniform Resource Locator (URL) address. In addition, the item may also include data packets from previous sessions that are updated on a new session at the same access point. The identifier is used to identify the content at the address provided by the server. The server is here accessed by sending the identifier to the link means to identify what type of content is requested from the server. In addition, the content is associated with the link content and the link content is provided at different locations within the server 320 or other servers 330, 340.

In addition, the item may include a script. The script is adapted to provide for accessing servers via link means. The script may activate or download link applications from the gateway, ie an application that enables receiving and / or transmitting different types of data packets between the server and the terminal. For example, the different types of data packets may be in a specific text format, software programs, picture format. This can be done by creating extensions to WML and WML scripts. Thus, the script may enable accessing the data packets by downloading an appropriate application directly supporting the data format of the type to the terminal that cannot support data packets by the software in the terminal. In general, the data packets may be data (content) stored or generated at the origin server 320. The contents of the data packet are typically displayed or interpreted by the client. This allows a standard WAP browser to be used and provides flexibility for service providers with location information supported by new features, e.g. different formats depending on the request. This can be done by creating extensions to WML- and WML script- and XML-documents. Thus, the script may enable accessing the data packets by downloading an appropriate application directly supporting the data format of the type to the terminal that cannot support data packets by the software in the terminal. In general, the data packets are data (content) stored or generated at the origin server. The contents of the data packet are displayed or interpreted by the client. For example, one service provider may support a data packet containing location information given by a satellite receiver, another server may support location information provided by cell identity information, and a third may request some location information. I never do that.

Instead of displaying the received content on a display provided on a telephone, it is also possible to provide the contents by a speaker that can be formed in the telephone or connected to the outside of the telephone.

As mentioned above, the wireless application environment forms the upper layer of the WAP stack and includes the browser application. The terminal is provided with a browser application such as the so-called microbrowser to access different servers. The browser application is arranged to establish a session with at least one gateway by reading the item in the memory. The browser application may also be provided with pull means for fetching the content including location information from the server 320 at the site indicated by the access point.

In accordance with the present invention, the terminal 300 includes a user interface (as shown by reference numbers 2, 3, 4, 5 and 6 in FIG. 1) that is connected to the browser application. The user interface includes a display for displaying content received from a server and user input means for controlling the browser by providing input to the browser application. The input means can be, for example, a keypad or voice recognition means for providing input to the browser application. An example of how the user interface can be displayed during a session is shown in FIGS. 5A and 5B. The input means is shown as the keypad 2 in FIG. 1. The browser can be arranged in a ROM memory or on a SIM card, as shown at 17b and 16 in FIG. 2, respectively. Thus, the input may be performed when the user presses a key on the keypad of the terminal and may activate a request to the servers 320 to 340. This request is arranged to be sent as a data packet through the transmitter. The input includes a query that identifies location information and is associated with at least one access point that indicates the site of server 320 to be accessed. The terminal may send this request to the server without transmitting any information about the location of the terminal, ie the request is independent of the location of the terminal 300. This means that the terminal 300 can send a request to the server to receive an indication of the location information, and does not reveal the location of the terminal when sending the request to the server. The input is provided to the request with the access point and is arranged to receive content from the server including an indication of the requested location information. In order to receive content with location information, the server 320-340 is provided with location means, which may comprise digitized maps and / or textual information on different locations. In this embodiment, the location means may be a deck of a language containing cards with the requested location information and supporting WAP such as WML, WML script or XML. It is also possible to have position means in other formats and to format the display of the position information in a format suitable for the link means.

In a preferred embodiment, the terminal may be connected to a position means 370 provided with a connecting means 380 to be input to the terminal. The location means may be a global positioning system (GPS) receiver or uses cell identity information. The connection means 380 may comprise a wired link or a wireless link (such as an infrared link or a low power RF link (eg, Bluetooth)). If the connecting means comprises a wired link, the connecting means may also comprise a cable provided with electrical plugs for physically connecting the locating means to the terminal. If the connection means is a wireless link, it is appropriate to provide an appropriate protocol to the terminal for controlling the location means. Naturally, the wired link should also be provided with a suitable protocol for controlling the location means. The location means 370 can provide greater flexibility to the user. For example, a user who wants to use a GPS receiver will be independent of the wireless network and may choose a less expensive solution that provides location information. Another example of location means is a user who wants to use the wireless communication network, and the user can receive cell identity information to obtain location information by using time difference information and / or by using time of arrival information. Thus, it is possible in particular to provide an input unit for input of the target position. The result of this input can also be presented by an output unit in said location means, in particular for the output of route guidance data. In order to process all the data, the location means further comprises a computer, in particular for route planning. The computer may include a memory having a digitized road map and may be connected to the server via a communication unit for data transmission. Therefore, it is possible to display the content received from the server on the positioning means, for example, by a display and / or a speaker connected to the positioning means.

Thus, in response to the request, the server may send a location request as an indication of the requested location information. This location request can be a WML-script, which is then processed by the browsing application. The location response from the terminal may then be a rejection of the location request, or send back a location response indicating the location of the terminal to the server. The position response can be provided by the positioning means as described above. After gathering the information about the location response, this information can be encoded, for example, into a binary representation of an XML-document. The output of this document encoding process, which is a binary representation of the XML-document, is then returned in the location response of the WMLScript request. This string is designed for the transmission to the link means, can be decrypted at the link means, and sent to the server as an XML document. Finally, the location response to the server may then fetch the content of the requested location information. This can be done by sending the requested location information via the link means back to the terminal. The presentation of the requested location information can be presented directly to the user of the terminal or presented to the terminal itself. If the presentation is performed on the terminal itself, it means that the terminal can update its own information. For example, if the user is driving or needs to focus on the driving, it is not always very convenient to request manually updated information. Thus, this feature automatically provides updated location information to the user without requiring any user interaction.

In a preferred embodiment of the present invention, the server is requested to have the actual location of the terminal, and this embodiment provides other methods of obtaining location information if the terminal cannot provide its own location information. do. If the terminal cannot obtain location information, the terminal may send a content type or header to the linking means to provide the requested location information to the server. The header fields allow the terminal to convey to the link means additional information about the location request and about the terminal itself. These fields act as request modifiers that have equivalent meaning to parameters on programming language methods (invocation). In this embodiment, it is preferable to use the above content type. This content type or header may include an indication that the terminal cannot provide this location information and may allow the user of the terminal to set options to search for alternative ways of obtaining the location information of the terminal. . Such a search can be performed, for example, by the link means or by the server itself. If the link means is to carry out a search for finding the position of the terminal, this information can be transmitted from the link means to the server, for example as an XML-document. In other words, the linking means may generate an XML document including the location information. The location information may be obtained from the cell identity information. The cell identity information is provided by the wireless telecommunications network by using time difference information and / or by using time of arrival information. If it is the server that performs a search to find the location of the terminal, this information will be processed by the server and generate the requested location information based on the obtained location information. The location information may also be obtained in the same manner as in the case of the link means provided by the wireless telecommunications network, ie by the cell identity information.

How to Provide Location Information from a Server to a Wireless Communication Terminal

4 shows a flowchart illustrating a method of providing location information from a server via a wireless communication terminal, in accordance with the present invention. In this example the wireless telecommunications terminal is of the same type as described in FIGS. 1 and 2, and the apparatus is also referred to hereinafter as a telephone. The phone is provided with a browser application and a memory that allows the user to browse among different objects on the server. The browsing can be performed by using a browser application that supports WAP. When the phone is activated and establishes a wireless connection to a wireless network, for example when the phone roams to a new network (“start”; step 500), different telecommunication services, for example WAP It is possible to communicate with related services, ie services that can be accessed from the server to the phone. By using this kind of service, it may be possible to obtain information from the server to the telephone, for example using a Short Message Service (SMS) or similar service.

First, the user can select a browser menu on a display controlled by the browser application connected to the memory. In this browser menu the user can choose to establish a session with the server. The server comprises, for example, location means in the form of text and / or digitized maps providing an indication of the requested location information. In this embodiment, the location means may be a deck containing cards with the requested location information in a language supporting WAP, such as WML, WML script or XML. It is also possible to have position means in other formats and to format the display of the position information in a format suitable for the link means. To set up the session, the user selects the service connected to the server from the menu. The selection is performed by pressing one of the softkeys, for example as shown in FIG. According to the invention, the selection also includes the input of positional information input by, for example, the soft keys irrespective of the position of the terminal. The browser application then reads and identifies a query identifying the item's content and requested location information from the memory (“read item”; step 510). This item includes at least one access point that indicates the location of the server being accessed. The item may include more content than the access point. For example, it is possible to have data packets received from a previous session being updated on a new session at the same access point. The memory may also be provided with an identifier, which is used to identify content at the server. After reading the item from the memory, the browser application generates a request (“request creation”) to receive an indication of the requested location information from the server at the location indicated by the access point. 520). The request includes an inquiry of the information and location information of the access point to be accessed, wherein the identifier identifies the content at the server. The information may be, for example, a URL address where the server is located. The request is then sent as a data packet via the transmitter.

In a preferred embodiment, the terminal may be provided with security means (not shown), which may require confirmation of the request sent to the server. The security means may be provided within the browser application and may be a default or optional feature. That is, the user may or may not interact. Thus, the security means may provide some privacy to the user and do not reveal any information to the third party without the user's permission. In other words, when the security means are activated, the user must confirm whether the user wants to send the request to the server. This confirmation can occur, for example, when the server requests the actual location of the terminal. The response from the server may then be a request for location information from the terminal, and the user may choose to accept and send the requested location information from the server. An important reason for having security measures is that in some cases the user reveals his or her location, which in some cases can be dangerous. For example, if you are not sure about the credit of the service provider. This means that if the request is processed at the server, a hacker can more easily find the user's location, or worse, can include a virus in the response returned to the terminal. In addition, when the terminal is connected to the location means as described above, this can reveal the location of the user directly. To avoid this, the WAP client, i.e. the terminal, should check the access point before the script function is executed when calling the WML script. The script is processed only if the WML script is requested or pushed from a trusted server that is listed in a specific location trusted server list. This list can be managed by the user. In addition, a crypto library may be a so-called WMLScript Crypto Library that may offer the possibility of signing the client's data with a digital signature before being sent to the origin server. In addition, this library offers the possibility of encrypting the user data before being transmitted.

In order to provide the ultimate location information to the server, the terminal can be connected to a location means. The positioning means may be a global positioning system (GPS) receiver or uses cell identity information. The location means can provide greater flexibility to the user. For example, a user who wants to use a GPS receiver will be independent of the wireless network and may choose a less expensive solution that provides location information. Another example of location means is a user who wants to use the wireless communication network, the user receiving cell identity information to obtain location information, for example by using time difference information and / or by using time of arrival information. Can be.

In order to establish a session between the link means and the terminal, the request is sent to the link means (" send request "; step 530). The link means is arranged to forward the data packets between the terminal and the server. The link means may be a gateway or proxy server linking the requested information to the correct access point. If the link means does not respond to the request, for example because the link means has failed or the terminal is out of range of the wireless network (" receive request? &Quot;; step 540), the terminal means May receive an error message indicating that a connection could not be established. The user may then choose to re-send the request once more (“Send Request”; step 530).

The item may include a script. The script is arranged to provide for accessing servers via the linking means. The script may activate or download link applications from the gateway, ie an application that enables receiving and / or transmitting different types of data packets between the server and the terminal. For example, the different types of data packets may be in a specific text format, software programs, different picture formats, and the like. This allows a standard WAP browser to be used and provides flexibility for service providers with location information supported by new features, e.g. different formats depending on the request. This can be done by creating extensions to WML- and WML script- and XML-documents. Thus, the script may enable accessing the data packets by downloading an appropriate application directly supporting the data format of the type to the terminal that cannot support data packets by the software in the terminal. In general, the data packets are data (content) stored or generated at the origin server. The contents of the data packet are displayed or interpreted by the client. For example, one service provider may support a data packet containing location information given by a satellite receiver, another server may support location information provided by cell identity information, and a third may request some location information. I never do that.

After the terminal is connected to the link means, the link means may control whether the access point is correct (“is the access point known?”; Step 550). For example, if the user no longer exists, misspelled it, or requested access to a server that is no longer known for some other reason, the link means may send an error message. This error message may then be displayed on the terminal to provide the user with information about the error (“Error Message Display”; step 560). The session can then be terminated by either the user or the link means (" terminate "; step 570). If the access point is known, the link means may send a pool to the server (“send pool to the server”; step 580).

In a preferred embodiment, the gateway can encode the content sent to the wireless terminal on the wireless network and can decode the data sent to the gateway by the wireless terminal. This means that the system, i.e., the terminal, the link means and the server, can be provided with encoding / decoding means which can enable rapid transmission of data packets between the server and the terminal. Thus, this enables the delivery of binary data packets that are much easier to deliver than unencoded data packets.

In addition, to provide a high level of security when transmitting wireless information, the system may also encrypt / decrypt data packets between the terminal and the server. The data packets include the request, the formatted request, the response and the formatted response. This means that the gateway is provided with encoders and decoders (not shown). The server also includes different algorithms for encrypting / decrypting. The encryption / decryption itself may be performed by well known methods, for example RSA, Diffie-Hellman and the like. One way to process data packets in binary format is to use the so-called WAP Binary Content Format (WBXML), such as the Wireless Binary eXtended Markup Language (WBXML).

Finally, if the server has sent the requested information to the link means, the requested location information will be further linked (pushed) from the link means to the terminal (“content display”; step 590). However, it is not necessary to display the received content, for example the received content may be stored directly in the memory. Finally, the session may be terminated by either the user or the linking means (“termination”; step 570).

Preferred embodiments will also be described with reference to FIG. 6 below. Some optional features in FIG. 6 are denoted by dashed lines / boxes. Box 600 represents a wireless communication terminal according to the present invention, which may be a telephone as described above. The phone can be installed in the car and connected to the car navigation system.

The browser application 608 in the phone 600 can provide the requested location information and generates a request that includes an access point representing the site of the server 602. This access point is preferably a uniform resource locator (URL) as known from various internet applications.

The location information request may be included within the URL itself or attached to the request as a separate document. The request 610 is sent to the link means 601, which is preferably a WAP gateway or so-called WAP proxy. The WAP proxy may receive the request from the phone 600 and forward the request directly to the server 602 (step 611). According to the format of the request 610 from the phone, the WAP proxy protocol / formats conversion in step 611 before being forwarded to the server 602. The request is then forwarded to the server 602 (step 612).

The request 612 is then processed at box 614 at the server site. The result may be that some instant location information may be returned to the phone, but in this example the result of the request processing is that the location of the phone is needed for the service.

Thus, the server 602 sends the indication of the requested location information to the WAP proxy 601 in a message 616. The message 616 preferably includes a WML script that includes a script function having the location of the phone 600. If the message 616 is received by the WAP proxy 601 and has not yet been encoded, the WAP proxy will encode the request at step 617. If so, the WAP Proxy 601 immediately forwards the message.

The encoded message is then sent to the phone 600 in step 618. The message 618 for obtaining the location information of the terminal 600 may be checked for security / privacy reasons in step 620 (ie, the user returns the user's location to the server in the display). Are asked if you agree). The user may allow the location to be transmitted or if the global agreement has been agreed in the previous step, the location information may be provided to this trusted server.

The received script function is then processed in step 622. During this process, the location of the terminal is gathered from any available positioning system, which may indicate the location of the phone as described above. The result of the script processing 622 is a string containing a representation of the location of the terminal in a format recognizable by the server 602.

This string is then optionally passed to the encoding means 628 (step 626). The exemplary format after encoding in step 628 may be a binary representation of an XML-document. It is then passed to the WAP proxy 601 via the transmitter of the phone 600 (step 630). The string may also be passed 624, 630 directly to the WAP proxy 601. An example of a return format at step 624 may be an XML-document.

The location message 632 includes the URL of the location request server in addition to the location information. If the string containing the location information has already been encoded in the phone 600, the WAP proxy decrypts the string in step 634 before being passed to the server in step 636, but optionally also the decoding is performed in the server. This may occur at step 638 at site 602.

However, if the terminal cannot provide location information and the server still needs to have the actual location of the terminal, there are alternative ways of obtaining this location information. Thus, we return once more to step 620, if the terminal can no longer obtain location information, the terminal can instead send this request of location information as a content type or header to the linking means. That is, step 632 is now a request instead of location information. The header fields allow the terminal to convey to the link means additional information about the location request and about the terminal itself. These fields act as request modifiers that have equivalent meaning to parameters on programming language methods (invocation). In this embodiment, it is preferable to use the above content type. This content type or header may include an indication that the terminal cannot provide this location information and may allow the user of the terminal to set options to search for alternative ways of obtaining the location information of the terminal. . Such a search may for example be performed by the linking means or in some cases by the server itself. If it is the link means to perform a search to find the location of the terminal, this information will be sent to the server, for example as an XML-document. In other words, the linking means may generate an XML document including the location information. The location information may be obtained from the cell identity information. The cell identity information is provided by the wireless telecommunications network by using time difference information and / or by using time of arrival information. If the server is to perform a search to find the location of the terminal, this information may be processed directly (or indirectly) by the server, and based on the obtained location information, the information may be requested. Create When the location information is processed directly, the server can retrieve the location information without sending a request to the terminal or the link means. The location information may also be obtained in the same manner as in the case of the link means provided by the wireless telecommunications network, ie the cell identity information.

The server 602 may now process the complete request 610 in step 642 and return the requested location information to the WAP proxy 601 in step 644. The response message 644 preferably includes a WML document. If the location information has not yet been encoded by the server, the location information is encoded by the WAP proxy 601 in step 646 and then forwarded to the phone 600 in step 648.

Each time messages are sent between the WAP proxy 601 and the phone 600 a communication session needs to be established or already established sessions can be used for this purpose. Before the WAP proxy 601 sends messages to the server 602 or the phone 600, the WAP proxy also checks whether the message format is supported by the receiving terminal. If necessary, the format is converted before the message is delivered.

If the requested location information is originally a request for traffic information, for example from a car navigation system in a vehicle, the received information is not necessarily presented to the user. The browser application delivers the information directly to the car navigation system and the car navigation system does not inform the user of the details of the traffic information, and routes the route to a destination based on the received traffic information. It may be possible to recalculate. A user of a car navigation system, for example, also does not need to know if the car navigation system has initiated a traffic information request before the car has reached a for example motorway which is part of a calculated route to its destination.

User interface

5A and 5B, an example of how a display may operate in a user interface when accessing a server in accordance with the present invention is shown. The user interface may comprise the same components as shown in FIG. 1, namely a keypad 2, a display 3, an on / off button 4, a speaker 5 and a microphone 6. The terminal is also provided with control means 18 as shown in FIG. 2 for controlling the user interface. Starting from FIG. 5A, there is a layout 31 that appears on a display in a telephone as shown in FIGS. 1 and 2, which layout 31 is from a wireless telecommunication network “D1 Telekom” 40. A clock representing the signal strength 35, battery power 45 and time 50 in hours and minutes is shown. Preferably, the display of the telephone is a liquid crystal display (LCD). The display can be controlled by the control means. The layout 30 shows an example of the telephone in an idle mode, ie when the telephone is activated and waiting for an operation, for example an incoming or making a call. At the bottom of the display are two items labeled "Menu" 55 and "Names" 60. If the user selects "names" 60, the user may have access to a built-in phone book, for example. When the user selects "menu" 55, the user may select from several different menus. The actual selection of features at the bottom of the display, such as "menu" and "names" is shown in FIG. It may be selected by the soft keys disclosed with reference to.

One of the menus may be the next layout 65 referred to as a "browser" 70. If the user chooses to use this menu, the user may have access to a different telecom associated with information services such as, for example, the Internet. One way to access this kind of information is to use Wireless Application Protocol (WAP).

When the user selects "home" 71, he moves to the next layout 75 which graphically shows "connecting to service" 80. This shows an example of how the phone is attempting to establish a connection to the Internet, for example by sending an access request to a server through a gateway. When a connection is established to the gateway, some kind of welcome phrase on the homepage, “Welcome to D1 Web.” 90 may be displayed. If the user selects "option" 90, the terminal connects to a server providing different services, the different services are graphically represented by the same layout 75, and "connecting to service" ( 80). When the terminal is connected to the service, a list of choices may be displayed as shown in the next layout 110. For example, the different selections may be "location information" 115, "white pages" 120, "pizza" 125, "CNN" 130, and the like. In this example, the user chooses to use the location information 115 and further browses the service in the next layout 135.

In FIG. 5B, reference numerals are 135 to 210. In the layout 135, the browser display shows the selected item. The selected item is displayed as a link to a service that provides location information. The user can select this item using the "options" 140.

For example, the layout may be provided with different editable fields and selection list placeholders shown in square brackets [] in this example. One selection in layout 160 may be highlighted (not shown), indicating a default state of the selection. In these fields, the user can locate, for example, a city or a street, such as "From: [Bochum] 170 to another location," To: [Dusseldorf]. 175 may be entered. Thus, when the user presses "Options" 180, the user may enter an editor to enter a location, for example the name of "Dusseldorf" 185, as shown in layout 187. will be. The user may then press Ok 190 when complete, or clear the location fields by selecting “Clear” 191.

If the user wants to continue his location related request and selects another city, the user selects [Graz]: "225 with the option" highlighted "on the selection, and layout Shown at 230. In the next layout 235, a selection list of available cities is displayed. The user selects the entry, for example by selecting "Gorden: 240" and selecting "Ok" 245. Next layout 250 highlights the selected city to receive location information. The user can then select "Options" 260, which in this example activates the calculation of the location and consequently "Gorden: Stau on route". 66 ...) ”265 is displayed with the selected information in the next layout 270. An arrow 280 indicates that there is more information to read and the user scrolls down, for example by softkeys. If the user can see the additional information.

The present invention is not limited to the above-described embodiments and the drawings, but may be modified within the scope of the appended claims. For example, it may be possible to make the reception of location information more flexible by providing the user with an option to specify which server the user wants to receive location information.
