Description: TIMING OF A SERVICE FILED OF THE INVENTION The present invention relates to telecommunication systems. In particular, the invention relates to a method and a system for the automatic timing of Push-type services based on the local time of the country of location of a mobile client visiting foreign countries . BACKGROUND OF THE INVENTION A Push-type service means a service in which the service content is transmitted to the user e.g. immediately after the service content has been published, or periodically, in periods determined by the user. Push services may be used in different telecommunication networks, e.g. on the Internet and in mobile communication networks. Push service information implemented in a mobile communication network is transmitted to the mobile station of the client e.g. by means of a short message. The use of push services in general requires that the client signs a service contract with an entity providing push services. When push services are offered to mobile cli- ents staying abroad (in different time zones) , the timing of the services functions based on the time of home country determined in conjunction with the order. In other words, if the client who has ordered the push service is staying in another country, e.g. in the USA, then a message that was ordered in Finland at 12.00 a.m. is received in the USA already at 6.00 a.m., or even earlier. In the GSM standards (GSM, Global System for Mobile communications) there is determined the format and the use of the time difference (Network time zone) . This has been presented e.g. in the standard GSM 04.08 Version 5.3.0 July 1996 of ETSI (ETSI, European Telecommunication Standardization Institute. The piece of information presented in the standard is, however, sent only to the mobile station. Further, for CAMEL services (CAMEL, Customized Applications for Mobile network Enhanced Logic) , a corresponding piece of time difference information has been determined, e.g. in the standard GSM 03.78 Version 6.2.0 Release 1997 of ETSI. This piece of time difference information is, however, not sent in conjunction with the location updating of the mobile station, i.e. the protocol does not support its transmitting to the home location register at all . The problem is that the automatic services offered to clients visiting foreign countries are timed according to the clock of the service provider and not to the clock of the country of residence of the client. It is possible for a mobile client to take into account the time difference when ordering, and based on this determine the transmission time. This kind of solution is, however, cumbersome and impractical. When the mobile client again changes the time zone, then the transmission time of a message in accordance with the push service should be again changed manually. OBJECTIVE OF THE INVENTION The objective of the invention is to eliminate the drawbacks referred to above or at least sig- nificantly to alleviate them. One specific objective of the present invention is to disclose a new type of method and system that enable one to adjust the transmission time automatically so that it depends on the actual location of the client. BRIEF DESCRIPTION OF THE INVENTION The invention relates to a more precise timing and delivering of the push services at the disposal of mobile stations. The invention enables one to time the messages received by a mobile subscriber visiting foreign countries that relate to the push services ordered based on the actual location of the mobile subscriber. The invention relates to a method for the re- timing of the push services connected with mobile stations based on the location of the mobile subscriber. In the method, a push service is activated for the mobile subscriber, and the transmission moment of the message connected with the service is determined. According to the invention, information relating to the mobile subscriber is transmitted to the provider of the push service based on the location update information of the mobile station. The information to be transmitted includes e.g. the subscriber identifier of the mobile subscriber and the location information of the subscriber, which consists of the country and operator code. At the information transmitted, it is possible to determine the time difference between the location of that moment of the mobile station and the location of the home operator of the mobile subscriber. The push service that was set is re-timed based on the aforementioned time difference, e.g. in such a way that the aforementioned time difference is subtracted from the transmission moment of the message originally determined for the service, or the aforementioned time difference is added to the transmission moment of the message originally determined for the service, depending on the location of the mobile station. The message connected with the push service is sent to the mobile subscriber in accordance with the new timing. The invention also relates to a method for re-timing the push services connected with a mobile station based on the location of the mobile subscriber in a telecommunication system which comprises a mobile switching center/visitor location register, a mobile station, from which there is a connection arranged to the mobile switching center, a home location register, from which there is a connection arranged to the mobile switching center/visitor location register, a push server, from which there is a connection arranged to the home location register, and a database from which there is a connection arranged to the push server. In the method, a push service is activated for the mobile subscriber. This is used to mean that the mobile subscriber separately orders the push services selected by him or her from the operator. In conjunction with the ordering of the services, a point of time is determined at which the mobile subscriber wishes to receive the messages connected with the push services ordered by him or her. When the location of the mobile station changes, a location update message is sent thereof to the mobile switching center/visitor location register. The location update message is preferably used to mean a location update message of the GSM system. The location update message is transmitted from the mobile switching center/visitor location register of the network to be visited further to the home location register. According to the invention, information relating to the identification and location of the mobile subscriber is sent from the home location register to the push server or some other network component. This kind of information is e.g. the subscriber identifier of the mobile subscriber or location information of the subscriber. The location information of the subscriber is used to mean e.g. the country code of the visitor location register and/or the operator code . The operator code refers to a foreign operator whose area the mobile subscriber visits. Based on the aforementioned information relating to the location, the piece of time difference information is determined. The piece of time difference information is used to mean the time difference determined based on the geographical position of the home country of the mobile subscriber and of the foreign operator or its mobile switching center. The location update message created by the mobile station triggers in the home location register a trigger, in the consequence of which information relating to the identification and location of the mo- bile subscriber is sent from the home location register to the push server or some other network component. The trigger facility is used to mean an event in which some predetermined event or message triggers the performing of some other predetermined event or func- tion. In one embodiment, the push server sends the inquiry message connected with the mobile subscriber to the home location register. The push service that was set is re-timed based on the piece of time difference information, e.g. so that the aforementioned piece of time difference information is added to or subtracted from the time of order set beforehand, depending on whether the mobile subscriber is located east or west of his/her home country. The message connected with the push service is sent to the mobile subscriber based on the new timing. The invention also relates to a method for re-timing the push services connected with a mobile station based on the location of the mobile subscriber in a telecommunication system which comprises a mobile switching center/visitor location register, a mobile station, from which there is a connection arranged to the mobile switching center, a home location register, from which there is a connection arranged to the mobile switching center/visitor location register, a push server, from which there is a connection arranged to the home location register, and a database from which there is a connection arranged to the push server. In the method, a push service is activated for the mobile subscriber. This is used to mean that the mobile subscriber separately orders the push services selected by him or her from the operator. In conjunc- tion with the ordering of the services, a point of time is determined at which the mobile subscriber wishes to receive the messages connected with the push services ordered by him or her. When the location of the mobile station changes, a location update message is sent thereof to the mobile switching center/visitor location register. The location update message is preferably used to mean a location update message of the GSM system. The location update message is transmitted from the mobile switching center/visitor location register further to the home location register. According to the invention, in the mobile switching center/visitor location register or some other network component, the piece of time difference information is added to the information to be transmitted to the home location register. This is preferably used to mean that the piece of time difference information that follows the geographical time zone division is added in the mobile switching center/visitor location register to the MAP protocol message (MAP, Mobile Application Part) . The piece of time difference information is advantageously used to mean the piece of time zone information. From the home location register, information relating to the identification and location of the mobile subscriber, as well as the piece of time difference information, is sent to the push server. The information relating to the identifi- cation and location is e.g. the subscriber identifier of the mobile subscriber or location information of the subscriber. The piece of location information of the subscriber is used to mean e.g. the country code of the visitor location register and/or the operator code . The operator code refers to a foreign operator whose area the mobile subscriber visits. The push service set is re-timed based on the piece of time difference information, e.g. so that the aforementioned piece of time difference information is added to or subtracted from the time of order set beforehand, depending on whether the mobile subscriber is located east or west of his/her home country. The message connected with the push service is sent to the mobile subscriber based on the new timing. In one advantageous embodiment, the piece of time difference information received from the location update message is saved to the home location register. In one advantageous embodiment, the location update message sent by the mobile station, or parts of it, is sent to the push server or some other corresponding system based on the location update message, including a subscriber identifier, a piece of location information of the subscriber, and a piece of time difference information. The invention relates to a system for retiming the push services connected with a mobile station based on the location of the mobile subscriber in a telecommunication system which comprises a mobile switching center/visitor location register, a mobile station, from which there is a connection arranged to the mobile switching center, a home location register, from which there is a connection arranged to the mobile switching center/visitor location register, a push server, from which there is a connection arranged to the home location register, and a database from which there is a connection arranged to the push server. According to the invention, the system comprises a message generator for sending the information relating to the identification and location of the mobile subscriber to the push server, a first data rec- ord, which comprises pairs of country code-operator code-time difference, and an application which receives the identification and location information relating to the mobile subscriber from the home location register and which retrieves the country code from the first data record saved to the database and by means of the operator code the time difference attached to it. In addition, the system comprises updating facilities for counting a new transmission time and for timing the point of time of transmission based on the aforementioned piece of time difference information, a second data record for saving the new point of time of transmission and the piece of time difference information, and a transmitter for sending the message connected with the push service to the mobile subscriber based on the re-timed transmission time. The invention relates to a system for retiming the push services connected with a mobile station based on the location of the mobile subscriber in a telecommunication system which comprises a mobile switching center/visitor location register, a mobile station, from which there is a connection arranged to the mobile switching center, a home location register, from which there is a connection arranged to the mobile switching center/visitor location register, a push server, from which there is a connection arranged to the home location register, and a database from which there is a connection arranged to the push server. According to the invention, the system comprises changing facilities for changing the message between the mobile switching center/visitor location register and the home location register so that a piece of time difference information is added to the message; a message generator for sending the information relating to the identification and location of the mobile subscriber to the push server, and update facilities for counting a new point of time of trans- mission and for timing the new transmission time based on the aforementioned piece of time difference information. In addition, the system comprises a second data record for saving the new point of time of transmission and the piece of time difference information, and a transmitter for sending the message connected with the push service to the mobile subscriber based on the re-timed transmission time. In one embodiment of the invention, the system comprises changing facilities for changing the MAP protocol so that the MAP protocol message to be sent to the home location register contains the piece of time difference information connected with the network element . In one embodiment of the invention, the home location register comprises connection facilities for connecting the piece of time difference information received from the location update message as a part of some trigger of the home location register. In one embodiment of the invention, the home location register comprises saving facilities for saving the piece of time difference information received from the location update message. The present invention enables one to automatically implement the timing of push services for clients visiting foreign countries. The time difference to be used in the transmission is determined based on the country of location of the mobile subscriber. BRIEF DESCRIPTION OF THE DRAWINGS In the following section, the invention will be described in detail by the aid of a few examples of its embodiments, in which Fig. la represents one advantageous embodiment of the invention, Fig. lb represents one advantageous embodiment of the invention, and Fig. 2 represents another advantageous em- bodiment of the invention. DETAILED DESCRIPTION OF THE INVENTION The system as shown in Fig. 1 comprises a mobile station MS (MS, Mobile Station) , from which there is a connection arranged to the mobile switching center/visitor location register MSC/VLR (MSC, Mobile Switching Center; VLR, Visitor Location Register) . The mobile switching center/visitor location register MSC/VLR is communicating with the home location regis- ter HLR (HLR, Home Location Register) , to which information relating to the mobile subscriber has been saved, e.g. location information and information relating to the identification of the mobile subscriber. In addition, the system as shown in Fig. 1 comprises an application PRGM, whose task is to receive the message relating to the mobile subscriber coming from the home location register HLR. The application PRGM may be located in the push server PUSH or it may be a separate component of the system. From the application PRGM there is a connection arranged to the push server PUSH. Attached to the push server PUSH is a database DB, to which information needed in the implementation of the push service has been saved, such as the identification information of the clients connected with the push service and the transmission moments of the messages connected with the service . The broken line between the mobile switching center/visitor location register MSC/VLR and the home location register HLR is used to describe the fact that the components on the left side of the line be- long to the sphere of the mobile communication network to be visited. The components on the right side are under the control of the home operator of the mobile subscriber. The example as shown in Fig. la assumes that a push service has been activated for the mobile subscriber. This is used to mean that the mobile subscriber separately orders the push services selected by him or her from the operator. In conjunction with the ordering of the services, the point of time is de- termined at which the mobile subscriber wishes to receive the messages connected with the push services ordered by him or her. When the mobile stations moves in the area of the mobile communication network, update information thereof is sent to the mobile communication network. One such piece of update information is the location update message, arrow la. The message is sent to the mobile switching center/visitor location register MSC/VLR, when one notices that the mobile station MS has changed the location area. The mobile switching center/visitor location register MSC/VLR transmits the location update message further to the home location register HLR, to which the former piece of location information of the mobile station has been saved, ar- row 2a. The location update message updates the former piece of location information in the home location register HLR with a new piece of information. The location update message contains information e.g. on what country the mobile station is located in, in the area of which mobile switching center/visitor location register MSC/VLR the mobile station is located, etc. The location update message is a message consistent with the mobile station standard. When the location of the subscriber MS changes, the home location register sends information to the application PRGM. The message generator GEN means the very method mentioned above that is used to send the information to the application PRGM. The home location register HLR sends to the application PRGM the subscriber identifier of the mobile subscriber and information relating to the location, arrow 3a. The piece of location information refers e.g. to the country code of the visitor location register of the mobile communication network to be visited and to the code of the operator controlling the mobile communica- tion network. When the application PRGM receives the information sent by the home location register HLR, it retrieves the country code from the first data record RECl and by means of the operator code the piece of time difference information attached to them, arrows 4a and 5a. Thus, there are pairs of country code- operator code-time difference saved to the first data record RECl. The application PRGM sends the piece of time difference information and the subscriber identi- fier further to the push server PUSH, arrow 6a. The push server PUSH comprises a function which adds to/subtracts the received time difference from the predetermined time of order of the push service and re-times the transmission of the message in accordance with the push service based on this. The updating facilities UPP are disposed in the push server PUSH to accomplish this functionality. The piece of time difference information and the new transmission time are saved to a second data record REC2 included in the da- tabase DB . The data records RECl and REC2 may be located in the same database DB. The above-mentioned functionality may also be located in another component than the push server PUSH. In the push server PUSH there is arranged a transmitter TRANS for sending the message connected with the push service to the mobile subscriber based on the re-timed transmission time. As shown by arrow 7a, the re-timed message connected with the push service is transmitted to the mobile switching center/visitor location register MSC/VLR and from it fur- ther to the mobile station MS. The message generator GEN, application PRGM, updating facilities UPP and the transmitter TRANS have been implemented by a way known in itself, e.g. by a computer or computer software, and are therefore not described in more detail in this connection. The system as shown in Fig. lb comprises a mobile station MS, from which there is a connection arranged to the mobile switching center/visitor location register MSC/VLR. The mobile switching cen- ter/visitor location register MSC/VLR is communicating with the home location register HLR, to which information relating to the mobile subscriber has been saved, e.g. location information and information relating to the identification of the mobile subscriber. In addi- tion, the system as shown in Fig. lb comprises an application PRGM. The application PRGM may be located in the push server PUSH or it may be a separate component of the system. From the application PRGM there is a connection arranged to the push server PUSH. Attached to the push server PUSH is a database DB, to which information needed in the implementation of the push service has been saved, such as the identification information of the clients connected with the push service and the transmission moments of the messages con- nected with the service. The broken line between the mobile switching center/visitor location register MSC/VLR and the home location register HLR is used to describe the fact that the components on the left side of the line belong to the sphere of the mobile communication network to be visited. The components on the right side are under the control of the home operator of the mobile subscriber. The example as shown in Fig. lb assumes that a push service has been activated for the mobile subscriber. This is used to mean that the mobile sub- scriber separately orders the push services selected by him or her from the operator. In conjunction with the ordering of the services, the point of time is determined at which the mobile subscriber wishes to receive the messages connected with the push services ordered by him or her. When the mobile stations moves in the area of the mobile communication network, update information thereof is sent to the mobile communication network. One such piece of update information is the location update message, arrow lb. The message is sent to the mobile switching center/visitor location register MSC/VLR, when one notices that the mobile station MS has changed the location area. The mobile switching center/visitor location register MSC/VLR transmits the location update message further to the home location register HLR, to which the former piece of location information of the mobile station has been saved, arrow 2b. The location update message updates the former piece of location information in the home location register HLR with a new piece of information. The location update message contains information e.g. on what country the mobile station is located in, in the area of which mobile switching center/visitor location register MSC/VLR the mobile station is located, etc. The location update message is a message consistent with the mobile station standard. When the push service wishes to make sure of the location of the mobile subscriber connected with the push service, it sends a location inquiry to the application PRGM, arrow 3b. The application PRGM di- rects the inquiry further to the home location register HLR, arrow 4b. As shown by arrow 5b, the home location register HLR sends information relating to the subscriber to the application PRGM. The message generator GEN means the very method mentioned above that is used to send the information to the application PRGM. The home location register HLR sends to the application PRGM the subscriber identifier of the mobile subscriber and information relating to the location. The piece of location information refers e.g. to the country code of the visitor location register of the mobile communication network to be visited and to the code of the operator controlling the mobile communication network. When the application PRGM receives the infor- mation sent by the home location register HLR, it retrieves the country code from the first data record RECl and by means of the operator code the piece of time difference information attached to them, arrows 6b and 7b. Thus, there are pairs of country code- operator code-time difference saved to the first data record RECl. The application PRGM sends the piece of time difference information and the subscriber identifier further to the push server PUSH, arrow 8b. The push server PUSH comprises a function which adds to/subtracts the received time difference from the predetermined time of order of the push service and re-times the transmission of the message in accordance with the push service based on this. The updating facilities UPP are disposed in the push server PUSH to accomplish this functionality. The piece of time difference information and the new transmission time are saved to the second data record REC2 included in the database DB. The data records RECl and REC2 may be located in the same database DB. The above-mentioned functionality may also be located in another component than the push server PUSH. In the push server PUSH there is arranged a transmitter TRANS for sending the message connected with the push service to the mobile subscriber based on the re-timed transmission time. As shown by arrow 9b, the re-timed message connected with the push serv- ice is transmitted to the mobile switching center/visitor location register MSC/VLR and from it further to the mobile station MS. The message generator GEN, application PRGM, updating facilities UPP and the transmitter TRANS have been implemented by a way known in itself, e.g. by a computer or computer software, and are therefore not described in more detail in this connection. The system as shown in Fig. 2 comprises a mobile station MS, from which there is a connection ar- ranged to the mobile switching center/visitor location register MSC/VLR. The mobile switching center/visitor location register MSC/VLR is communicating with the home location register HLR, to which information relating to the mobile subscriber has been saved, e.g. location information and information relating to the identification of the mobile subscriber. In addition, the system as shown in Fig. 2 comprises a push server PUSH. Attached to the push server PUSH is a database DB, to which information needed in the implementation of the push service has been saved, such as the identification information of the clients connected with the push service and the transmission moments of the messages connected with the service. The broken line between the mobile switching center/visitor location register MSC/VLR and the home location register HLR is used to describe the fact that the components on the left side of the line be- long to the sphere of the mobile communication network to be visited. The components on the right side are under the control of the home operator of the mobile subscriber. The example as shown in Fig. 2 assumes that a push service has been activated for the mobile subscriber. This is used to mean that the mobile subscriber separately orders the push services selected by him or her from the operator. In conjunction with the ordering of the services, the point of time is determined at which the mobile subscriber wishes to receive the messages connected with the push services ordered by him or her. When the mobile stations moves in the area of the mobile communication network, update information thereof is sent to the mobile communication network. One such piece of update information is the location update message, arrow 21. The message is sent to the mobile switching center/visitor location register MSC/VLR, when one notices that the location area of the mobile station MS has changed. The mobile switching center/visitor location MSC/VLR adds the piece of time difference information to the message to be sent to the home location register HLR. Beginning with the versions 6.1.0 of MAP 09.02, the time zone field is configurable and can be sent for CAMEL services. In that case, the necessary amendment is made in the MAP protocol and the time zone field is transmitted to the home location register HLR in a location update message, arrow 22. In the mobile switching center/visitor location register MSC/VLR there are arranged changing facilities CH, by which the protocol message between the mobile switching center/visitor location register MSC/VLR and the home location regis- ter HLR is changed. The mobile switching center/visitor location register MSC/VLR transmits the specified location up- date message to the home location register HLR, the aforementioned message containing a piece of time zone information. The location update message updates the former piece of location information in the home loca- tion register HLR with a new piece of information. The location update message contains information e.g. on what country the mobile station is located in, in the area of which mobile switching center/visitor location register the mobile station is located, etc. When the location of the mobile station MS changes and the mobile switching center/visitor location register MSC/VLR sends a location update message thereof, the home location register HLR sends a message thereof to the push server. The message generator GEN is used to mean a method by which the message is created and sent to the push service PUSH. The piece of time zone information may be included in the message created by the home location register HLR and/or it may be saved to the home location register HLR. The saving facilities SGE are disposed in the home location register HLR for saving the piece of time zone information. The connection facilities CON are used to connect the piece of time zone information received from the location update message as a part of the mes- sage to be transmitted to the push server PUSH. The home location register HLR sends to the push server PUSH the subscriber identifier of the mobile subscriber, information relating to the location, as well as the piece of time zone information, arrow 23. The subscriber identifier is used to mean e.g. the MSISDN number or some other subscriber identifier. The piece of location information refers e.g. to the country code of the mobile communication network to be visited and to the code of the operator controlling the mobile communication network. The piece of time zone information refers to the piece of time differ- ence information which is derived by comparing the local time with the international mean time. The push server PUSH comprises a function which adds to/subtracts the received time difference from the predetermined time of order of the push service and re-times the transmission of the message in accordance with the push service based on this. The updating facilities UPP are disposed in the push server PUSH to accomplish this functionality. The piece of time difference and the new transmission time are saved to the second data record REC2 included in the database DB. In the push server PUSH there is arranged a transmitter TRANS for sending the message connected with the push service to the mobile subscriber based on the re-timed transmission time. As shown by arrow 24, the re-timed message connected with the push service is transmitted to the mobile switching center/visitor location register MSC/VLR and from it fur- ther to the mobile station MS. The changing facilities CH, message generator GEN, saving facilities SGE, connection facilities CON, updating facilities UPP and the transmitter TRANS have been implemented by a way known in itself, e.g. by a computer or computer software, and are therefore not described in more detail in this connection. The invention is not restricted merely to examples of its embodiments referred to above, instead many variations are possible within the scope of the inventive idea defined by the claims.
