Method for directing formation of a telecommunications contact
The present invention relates to a method, according to the preamble of Claim 1, for controlling the formation of a data communications connection, in which method a data communications connection formation request is sent in the direction of a telecommunications network in response to a selection signal concerning a graphic image.
According to the state of the art, in the method disclosed in patent application publication EP 797 338, three-dimensional virtual models are run in a server system. In the method, a selection signal concerning a specific point in a three-dimensional virtual- reality model is received in a data communications network from the direction of the customer system and a real-time data communications connection is commanded to be formed between the subscriber number of the selected destination and the customer system. In the method disclosed, a computer sound card is used for sending and receiving speech. IP (Internet Protocol) technology is used for transmitting speech.
A drawback of the state of the art is that the three-dimensional virtual model used to define the location of the selectable destinations is complex, so that only a small number of virtual-reality worlds are available, while the known methods cannot be applied to environments, of which virtual-reality worlds have not been formed. In known solutions, the speech properties of a desktop computer are based on IP (Internet Protocol) call technology, there being no guarantee of the quality of speech transmitted according to this technology, in a public telecommunications network.
The invention is intended to eliminate the defects of the state of the art disclosed above and for this purpose create an entirely new type of method for controlling the formation of a data communications connection.
The invention is based on receiving, from the direction of a telecommunications network, location data on at least one monitored terminal element, such as a mobile station, after which a display element is commanded to show a graphic model, in which the location of at least one monitored terminal element is shown as an icon. The user of
the terminal element controlling the display element is provided with the opportunity to indicate at least one monitored terminal element, through an interface connected to the display element. After this, a selection signal is received, from the direction of the interface of the display element, which relates to at least one icon, which in turn depicts the location of at least one monitored terminal element. Finally, in response to the selection signal relating to an icon, a data communications connection formation request, concerning the identity of the indicated terminal element, is sent in the direction of the telecommunications network.
More specifically, the method, according to the invention, for controlling the formation of a data communications connection, is characterized by what is stated in the characterizing portion of Claim 1.
Considerable advantages are gained with the aid of the invention. When defining the location of the monitored terminal element, it is possible to use a simple map base, which allows the method to be applied in desired environments. The data communications connection to be formed is provided through a public telephone network (PSTN) and/or a mobile network (PLMN), so that the quality of speech transmitted using the data communications connection can be guaranteed to meet the standards set for a public telephone network and/or a mobile network.
A preferred embodiment of the invention is the observation of the location of monitored mobile stations from a display element, and commanding a data communications connection to be formed between the mobile station at the most appropriate place in terms of location and the desired terminal element. The method according to the invention can be advantageously applied in control centres of companies providing transportation services for goods and people. With the aid of the method, it is possible to facilitate the operation of rescue service organizations while it can be conveniently used to control home-care, assistance, repair, and cleaning groups, and similar mobile units. By means of the method according to the invention, a data communications connection, such as a telephone connection, can be conveniently formed between the customers of service entrepreneurs like those referred to above and the most appropriate place, such as the service person that is closest. In rescue service and other protection tasks, the method
according to the invention can be used to form a data communications connection between fixed or mobile terminal elements in the area of operations, making it possible to create communications contacts between the rescue service personnel using the terminal elements, for example, if it is necessary to evacuate the area of operations. In the following, the invention is examined with the aid of an example and with reference to the accompanying drawing.
Figure 1 shows an operational diagram of one method, according to the invention, for controlling the formation of a data communications connection.
The following numbered elements are used in Figure 1 :
The momtored terminal element 10 is a terminal element connected to a mobile network through a mobile capability, location monitoring messages corresponding to the location of which are received in a telecommunications network.
The backbone network 11 of the mobile network is a backbone network of a mobile network that includes at least one base station and a short message centre 12.
The short message centre 12 is a short message centre, which is set to receive location data defining the location of the monitored terminal element 10 or some other monitored terminal element.
The positioning database 13 is a database, which is set to receive and record the location data of at least one monitored terminal element from the direction of the short message centre 12.
In the method according to the invention, in addition to, or as an alternative to the positioning database 13, an installation address database 14 is typically used, which is a database containing the network addresses of the terminal elements of a landline network or similar location data.
The IN centre 15 is a centre performing IN capabilities, i.e. intelligent network
functions, operating in a telecommunications network, such as a telephone network or mobile network. In the IN centre 15, there is preferably a capability in accordance with an extension known by the product name C-SHOP.
The IN database 16 is a database, which is under the control of the IN centre 15, and in which the network address, relating to the identity of at least one momtored terminal element, is defined. In the method according to the invention, the IN centre 16 can be a centre equipped with, for example, the IN properties of either a landline network or a mobile network, and their supplementary additional properties. The supplementary additional properties can be particularly additional properties, which permit the programming of settings through a network. One such known additional property package in an extension known by the product name C-SHOP.
The monitoring terminal element 17 is a terminal element, which is set to control a display element to show graphically a location corresponding to a location data message that it receives. The monitoring terminal element can be, for example, a PC workstation or a map system program operating in a mobile station.
The terminal element 18 that has a fixed location is a terminal element, the network address of which is defined in an installation address database.
The second monitored terminal element 19 is a terminal element connected to a telecommunications network through a mobile capability.
The extra terminal element 20 is a terminal element connection to a telecommunications network through mobile capability or with a fixed location.
The display element 21 is an element, which is arranged to show graphic icons in locations determined by a command and to update its display in response to a command coming from the direction of the monitoring terminal element 17. The display element can be, for example, the display of a computer or a mobile network terminal.
In the method according to the operation diagram of Figure 1, the following stages are
carried out. Stages 101 and 102 are carried out to send location information on the monitored terminal element to the monitoring terminal element.
101) Location data on the momtored terminal element 10 is received from the direction of the momtored terminal element 10, over the backbone network 11 of a mobile network including a short message centre 12.
102) In the positioning database 13, the location data of the monitored terminal element 10 is received from the direction of the short message centre 12, recorded, and sent, if necessary, in the direction of the monitoring terminal element 17.
Stages 103 - 104 are carried out, so that the user entity of the display element 21 can get an estimation basis for indicating the icon relating to their desired terminal element.
103) The location date of the monitored terminal element 10 is received from the direction of the positioning database 13, by means of the monitoring terminal element 17.
104) The display element 21 is commanded to show a graphic model, in which the location of the monitored terminal element 10 is shown as an icon.
Stages 105 - 106 are carried out to send routing signalling in the direction of the telecommunications network, by means of which notification is made of the destination or destinations for the formation of the desired data communications connection.
105) A selection signal concerning the icon representing the location of the monitored terminal element 10 is received from the direction of the interface of the display element 21. The received selection signal can be formed, for example, as a result of a map image being shown of the display of a PC workstation, on which an icon is placed, representing the location of the terminal element 10, according to the received location data, and after this a selection targeting this icon with the mouse of the PC workstation is received.
106) A data communications connection formation request, concerning the identity of the terminal element 10 and the identity or network address of the terminal element 18 with a fixed location, is sent in the direction of the IN centre 15.
Stages 107 - 109 are carried out in order to form a data communications connection between the monitored terminal element 10 and another terminal element utilizing the application environment used, or other terminal elements utilizing the application environment used.
107) A query concerning the network address corresponding to the identity of the momtored terminal element 10 is sent from the IN centre 15 in the direction of the database 16.
108) The network address corresponding to the identity of the momtored terminal element 10 is received from the direction of the IN database 16.
109) By means of the IN centre 15, a data communications connection is commanded to be formed between the monitored terminal element 10 and the terminal element 18 with a fixed location and possibly some other terminal elements utilized in the used application environment, or other terminal elements utilizing the used application environment, such the second momtored terminal element 19 and/or the extra terminal element 20.
The invention can also be applied in a manner differing from that above:
Alternatively, the location data can be computed using a capability of some telecommunications network element, such as a mobile communications centre operating in the backbone network of the mobile network, and sent in the direction of the positioning database 13, to be recorded. Generally, very many other kinds of positioning method can also be applied in connection with the invention. One possible method is disclosed in publication WO 0022862. In the method of the publication, the location of the network terminal is sent in co-ordinate form to the location database. In a preferred
embodiment, a satellite-positioning device is connected to the network terminal and the location data is sent automatically to the database, for example, as an SMS message.
The identity of at least one extra terminal element 20 can be defined in the IN database 16, in which case there is no need to send more than the identity of the momtored terminal element 10 in the direction of the IN database.
With the aid of the method according to the invention, it is possible, for example, with the aid of a cursor, to select at least two positioned terminal elements, such as mobile stations, from the display element 21 and to command a data communications connection to be formed between them. This can be implemented, for example, by connecting the positioned terminal elements in a conference-call type connection within the framework of the properties of the IN centre 15 or of some other used connection field, such as an IP (Intelligent Peripheral) device.
Selection can take place by indicating some positioned telephone device indicated with the aid of a preferred mark. Indication can be implemented by means of a map system, for example, by 'clicking', by the drag-and-drop method, or by drawing a path between the symbols. As a result of this, a selection signal concerning the icon depicting the location of the monitored terminal element is received from the direction of the interface of the display element, and a data communications connection formation request concerning the identity of the monitored terminal element is sent in the direction of the telecommunications network, in response to the selection signal concerning the icon depicting the location of the monitored terminal element.
The invention has several advantageous practical applications.
For example, the method according to the invention can be applied so that, in connection with the terminal element 17 a map base is displayed by the display element 21, showing the free taxis in the area. In this embodiment, customers can select the taxi they want from the display, in which case the reservation is transmitted to the taxi together with the customer's address. An acknowledgement message, which is set to signify that the taxi is coming, is sent to the monitoring terminal element 17.
The above taxi application can also be implemented by using different symbols to represent different kinds of taxis. Thus, different symbols can be used, for instance, for private-car type taxis and for minibuses, allowing customers to choose a vehicle corresponding to the amount of space they need. Similarly, station wagons can also have their own specific symbol.
The above taxi applications can also be developed in such a way that, in addition to the free taxis, taxis that are reserved and/or will soon be free are also shown on the map base. Thus, each group can be shown in a specific way, for example, so that the symbol for free taxis is green, for reserved taxis red, and for those soon to be free orange.
The taxi application described above can be utilized, for example, in a regional taxi reservation centre, which provides taxi reservation services for taxi customers. The taxi application can alternatively also be provided so that it is directly available to taxi customers, for example, through the Internet. One extremely attractive application is a taxi reservation service that is available through a UMTS terminal. In such an application, a map base of the area in which they are could be displayed to taxi customers, with the taxis moving in the area being shown by symbols. In a highly preferable embodiment, the customer's own location would also be shown by a specific symbol on the map base. In that case, the system would thus also have to know the location of the mobile customer.
By means of a corresponding principle, it is also possible to implement many other kinds of services relating to the movement and location of a certain group, for example, the monitoring of other moving service providers. In such services, it is possible to send the telecommunications network a request to form a data communications connection concerning a terminal element selected from the display element 21 and to route an acknowledgement coming from the direction of the momtored terminal element 10 to the monitoring terminal element 17. The data communications connection formation request can be used as a service-ordering message in connection with the terminal element 10. The acknowledgement coming from the direction of the monitoring element can be used as an order confirmation.
The method according to the invention can also be used in such a way that the location of at least one monitored terminal element is defined from the interface of at least one monitored terminal element, to be transmitted to the monitoring terminal element, or to a specific group of monitoring elements. In practice, the location of one's own terminal element is then defined to be displayed to the desired reference group. One such embodiment could be, for example, a service in which the mobile-station users could form, for example, groups of friends. Thus, in the service it would be possible to display, for example, on a certain selected city map, the locations of all the members of a group who are located, at the moment in question, in the area of the selected map base and who have not temporarily prevented their locations from being displayed. Such a group could define viewing rights, for example, to be granted only to members of the group, or if they desired, they could also grant open viewing rights. Thus it is possible to provide, for example, groups of friends a service in which it is possible to monitor the location and movement of friends, for example, with the aid of an Internet or mobile network terminal, such as a UMTS terminal.
