METHOD AND SYSTEM FOR TRANSMITTING CONNECTION TIME

Abstract: The invention relates to a method and a system for transferring connection time in a telecommunication system easily in such a way that the transfer of connection time is ordered by a short message, and the recipient is sent a notification message informing of the transfer of connection time. The transfer of connection time happens by directing the debiting ticket to the account of the buyer, and correspondingly, by crediting the account of the recipient.

Description: METHOD AND SYSTEM FOR TRANSMITTING CONNECTION TIME. The invention relates to telecommunication systems. In particular, the invention relates to a method of transferring connection time m a telecommu- 5 nication system m which the mobile station of the subscriber sends a service request to the connection time server connected to the telecommunication network, which copies the request further to tne database and confirms the service request by sending a message 10 to the mobile station of the subscriber, and the user replies to the confirmation message with the mobile station, after which the connection time server enters a ticket m the database indicating a successful provision of the service and sends a message informing of 15 the succeeding of the service to the mobile station of the subscriber. PRIOR ART The provision of services based on short mes- 20 sages is becoming common. The sending of short messages is easy to a client who has got a mobile station belonging to the global system for mobile communications (GSM, Global system for Mobile Communications) . The short message service enables one to send 25 between mobile stations short messages that contain typically up to 160 characters. The transmission of messages does not require that the mobile station is switched on. If the mobile station cannot be reached, the message is saved to the short message service cen- 30 tre. The short message service centre saves the message for several days, and if the mobile station receiving the message s activated m the area of the mobile network, then the message is sent to the mobile station. Messages are being transmitted either m the 35 area of the same cell or to other cells by means of the roaming feature of the mobile station. Short es- sages may be sent also to other devices, such as digital telephones or e-mail messages. By means of the short messages, different services are implemented. Typically, a message that is often of a fixed form, is sent to the network. In the network, the message is directed to the server of the service provider, in which the content of the message is interpreted, the rights of the sender of the message are checked, and the service is implemented to the sender of the message. As a service example let it be mentioned a weather service that is located on the Netgate server and is implemented by a short message. One specific problem becomes the transfer of connection time. The subscriber wishes to give connec- tion time to the recipient, typically to a certain subscriber line. Often the subscriber is a person in a better financial status, e.g. a parent who wants to support the operating costs of the mobile station of his or her child. Previously known is a solution which solves the problem in question. Previously, a person ordering connection time has visited a telephone service shop, in which the subscriber has filled in an crder form of connection time. The seller of the connection time has in turn credited the telephone bill account of the recipient. The solution is not advantageous because the purchaser of the present has had to visit the shop on site . The objective of the present invention is to eliminate or at least to alleviate the problems referred to above. The objective of the invention is also to enable the transferring of connection time easily using the possibilities provided by the short message service in such a way that the account of the mobile station of the subscriber is debited when buying connection time. BRIEF DESCRIPTION OF THE INVENTION By means of the invention, the owner of the mobile station orders connection time using the short message service. The recipient of the connection time gets a message informing of a successful transaction. The invention relates to a method m which the subscriber writes a service request of a fixed form m the short message. The service request is transmitted, e.g. as a short message to the connection time server connected to the telecommunication network. The connection time request is recognized by the connection time server, the connection time request is saved to the database and a confirmation message is sent to the subscriber. The subscriber reads the con- firmation message, and if the information of the confirmation message is correct, then he or she sends an acknowledgement message to the connection time server. The connection time server receives and processes the confirmation message. If the subscriber still wants to send the connection time request, then a ticket is sent to the database that debits the account of the subscriber and credits the account of the recipient. After this, the connection time server sends a notification of the connection time request to the mobile station of the recipient. Typically, a connection time request consists of the identifier of the recipient and of that of the subscriber, a greeting message, the price of the connection time and a reference number. The confirmation message consists of the identifier of the service and of a reference number. The notification message comprises a greeting message and the price of the connection time. Usually the connection time request, confirmation message and the notification of the transfer of the connection time are transmitted in a global systems for mobile communications. The short messages are transferred from the mobile station to the connection time server via the short message service centre. The equipment that is needed m transferring connection time consists of a processing module which is located m the connection time server. The processing module handles the request for the connection time transfer sent as a short message by saving the request to the database and by creating both a debiting ticket and a crediting ticket which are sent to the billing system. Usually, as a connection time server, a Net- gate server is used m which the database usually is located. In one embodiment, the user has agreed with the telephone operator that advertisement messages can be sent to his or her mobile station. As a favour m return, the telephone bill of the user is credited once a month. At the turn of the month the advertising agency sends the following message to the user: "transfer of speech tιme#0405123456#30#H ! You have received 30 advertising messages m this month. Thank you for using the service. Best regards, the advertiser" . The message is handled by a method m accordance with the invention and finally the user is sent the following message: "Hi! You have received 30 ad- vertismg messages m this month. Thank you for using the service. Best regards, the advertiser. Your account will be credited with speech time of the value of 30 marks. Best regards, billing department". As compared with prior art, tne invention provides the advantages that the connection time request is transmitted as a short message. This makes it possible to provide totally new services, examples of which were briefly presented above. BRIEF DESCRIPTION OF THE DRAWINGS In the following section, the invention will be described m detail by the aid of a fev. examples of its embodiments with reference to the accompanying drawing, in which Fig. 1 represents one system in accordance with the invention; Fig. 2 illustrates one flow chart of a method in accordance with the invention; Fig. 3 represents one embodiment in accordance with the invention; and Fig. 4 represents one embodiment in accor- dance with the invention. DETAILED DESCRIPTION OF THE INVENTION Fig. 1 represents one system in accordance with the invention. The mobile station of the sub- scriber MSA is connected to the short message service centre SMSC via the telecommunication network MCN. As the telecommunication network, e.g. a global system for mobile communications is used. The short message service centre SMSC is connected to the connection time server CTPS, which handles the service request sent by the subscriber. From the connection time server CTPS there is a connection to the database DB, to which information is saved relating to successful service requests, a debiting ticket which is used to debit the account of the buyer of the connection time, and a crediting ticket which credits the account of the recipient of the connection time. When the connection time request has been handled, a short message is sent from the connection time server CTPS to the mo- bile station MSB of the recipient of the connection time via the short message service centre SMSC. Fig. 2 illustrates one diagram of a method in accordance with the invention. At first, the subscriber writes a service request, block 21. The serv- ice request is sent via the short message service centre to the connection time server, block 22. The connection time server recognizes the service needed and saves the piece of information from the connection time card to the database, block 23. The connection time server sends a confirmation message further to the mobile station of the subscriber, block 25. The subscriber replies to the confirmation message, as shown by block 26, after which the message is sent back to the connection time server. The connection time server confirms the connection time request, and if the confirmation is correct, provides the service, block 29. The connection time server sends a notification informing of the service to the recipient of the present, block 211. Fig. 3 represents one embodiment m accordance with the invention. Figs. 3a-3h represent the display of a mobile station. In the embodiment, a parent wishes to give his or her child connection time at the value of 100 marks as a Christmas present. For the connection time request, the parent writes a short message which is of the following form: "transfer of speech tιme#0405123456#100# Hi! Here is a Christmas present for you, regards, Pekka" , Figs. 3a and 3b. The message is sent to the connection time server, e.g. to number 400. Next, the connection time request is confirmed, so the connection time server sends the parent a confirmation message as shown m Figs. 3c and 3d. If the parent accepts the service, he or she replies to the confirmation message by sending an acknowledgement message as shown by Fig. 3e to the connection time server. In that case, the connection time server up- dates the account data of the mobile stations m the database and sends a notification message to the mobile station of the recipient. The notification message is, e.g. of the following kind: "Hi! Here is a Christmas present for you, regards, Pekka. Your ac- count will be credited with speech time of the value of 100 marks. Best regards, billing department, Figs. 3f, 3g and 3h. Fig. 4 represents one embodiment in accordance with the invention. In the embodiment, the user participates in a radio quiz in which the prize is speech time for the value of 500 marks. The user an- swers correctly the question made in the radio and wins connection time. Consequently, the organizer of the contest sends the user the prize as shown by the invention, a short message which is, e.g. of the following form: "transfer of speech time#0405123456#500#Hi ! You won a radio quiz. Here is you present. Best regards, radio quiz", Figs. 4a and 4b. The message is confirmed, in which case the organizer of the contest is sent a confirmation message, Figs. 4c and 4d. The user acknowledges the confirma- tion message by a message as shown by Fig. 4e. Finally, the user receives a message of the following form: "Hi! You won a radio quiz. Here is you present. Best regards, radio quiz" . Your account will be credited with speech time of the value of 500 marks. Best regards, billing department", Figs. 4f, 4g and 4h.
