Description: Method and system for information distribution BACKGROUND OF THE INVENTION The present invention relates to a method for distributing information from at least one Information Provider to at least one Customer device. It also relates to a system for distributing information from at least one Information Provider to at least one Customer device. Furthermore it relates to a Customer device and an Access Service Provider. RELATED ART Methods for distributing information of the kind mentioned above exist today. One example is display of commercial information to Internet customers when they are browsing the web during the loading of web pages. A problem with these existing methods is that they are limited to only distribute the information when the customer is using a particular application, for example web browsing. Another problem is that it is not possible to make a selection among the customers in the distribution. A further problem is that the information providers can not check that the information has been displayed correctly to the customer. SUMMARY An object of the present invention is to improve the interplay between information providers and customers and also between different customers as to distribute in- formation. It is also an object of the invention to provide a method and a system for distributing information to customer devices and presenting the information to the customers effectively. This is achieved by a method of the initially defined kind comprising the steps of: - sending information from at least one of the Information Providers to an Information Publisher; - comparing the content of the information with information about the customers stored in customer profiles in the Information Publisher; - distributing the information to all the customers corresponding to a certain fea- hire described in the customer profile; - receiving and processing the information in at least one Information Receiver in each concerned Customer device; - notifying the customer by displaying at least a part of the information on the Customer device. It is also achieved by a system of the initially defined kind characterised in that it comprises: - an Information Publisher connected to the at least one Information Provider and adapted to distribute information received from the Information Providers ac- cording to information about the customers stored in customer profiles in the Information Publisher; - an Information Receiver located in each Customer device adapted to receive and process the information received from the Information Publisher; - an Information Presenter connected to the Information Receiver in each Cus- tomer device adapted to notify the customer by displaying at least a part of the information on the Customer device. It is also achieved by a Customer device comprising such an Information Receiver and Information Presenter and an Access Service Provider comprising such an Information Publisher. With this method, system, Customer device and Access Service Provider information can be delivered to the customers according to their desires or according to other information about the customers such as their location and the information can be displayed to the customers right away. Preferably the method further comprises the steps of: - establishing the connection between a Customer device and the network through a first interface; - informing the Information Publisher through a second interface that is separated from the first interface that this specific Customer device is connected to the network. This second interface is preferably a higher level of the first interface and thus just a .logical connection. Suitably the distribution of information to the customers is done through the second interface. Hereby the information could be displayed to the customer regardless of what kind of application he is using for the moment. Preferably the distribution of information is dependent on the customers 5 desires and/or location. Suitably at least one address of each Customer device is placed in at least one specific list depending on what kind of information the customer should be notified with. The customer could be notified by only displaying a notic has been received. Either could the information be displayed to the customer for a predetermined time period or until the customer confirms the receiving by for example clicking on the information. Preferably the information that should be distributed to a certain customer is queued in the Information Publisher if the customer not is logged on for the moment and distributing the information to the customer as soon as he logs on. Suitably the Information Receiver checks if the information is correctly displayed in the Customer device and sends a fault message to the Information Publisher if the information was incorrectly displayed and/or a success message if the information was correctly displayed. Preferably a Network Access Server is instructed from the Information Publisher to disconnect the Customer device if a fault message was received in the Information Publisher and/or rewarding the customer if a success message was received. Suitably the method also comprises the steps of: - sending instructions to the Information Publisher from a Customer device telling that a specific information should be distributed to for example the customer's friends or colleagues; - distributing this information to other Customer devices according to the instructions from the customer, this distribution of information being done in the same way as the distribution of information from the Information Providers. Advantageously SIP (= Session Initiation Protocol) is used as the transport protocol.

DETAILED DESCRIPTION OF EMBODIMENTS Fig. 1 is a schematic view of an Access Service Provider 1 communicating with a Customer device 3 and providing information to the customer according to a first embodiment of the invention. The Access Service Provider 1 provides the customer with a connection to a backbone network 5. The Access Service Provider 1 comprises a Network Access Server 7 connected to the network 5 and an Information Publisher 9 connected to the network 5 and to the Network Access Server 7. A number of Information Providers 11,13,15 are connected to the. Information Publisher 9 and to the network 5. The Customer device 3 comprises a Communication Stack 17, which is connectable to the Network Access Server 7 through a first interface II . It comprises also an Information Receiver 19 connectable to the Information Publisher 9 in the Access Service Provider 1 through a second interface 12. This second interface 12 could be a higher level of the first interface II and is thus just a logical connection. Furthermore the Information Receiver 19 is connected to an Information Presenter 21 in the Customer device 3. The Information Presenter 21 is adapted to notify the customer by displaying the information received in the Information Receiver 19 in the Cus- tomer device. The displaying of the information in the Cu no interaction with the Communication Stack 17. This reduces the risk for manipulation by not trusted customers. The Information Receiver 19 and the Information Presenter 21 could be provided in the same unit in the Customer device 3, and the Information Providers 11,13,15 could be provided in the same unit as the Information Publisher 9 in the Access Service Provider 1. The connection between the Information Publisher 9 and the Network Access Server 7 is an interface, here called the third interface 13. When a customer who is using the Customer device 3 logs on to the network through the first interface II the Information Receiver 19 informs the Information Publisher 9 through the second interface 12 that this specific customer is logged on. The Information Publisher 9 comprises information about the customers who are joining this information service. The information about the customers could for example be information about what kind of information they are interested in receiving or if they are customers who receive free internet access in exchange to accepting commercial information. It could also be other kinds of information about the customers such as their age and their location. All the information about the differ- ent customers could be stored in a customer profile in the Information Publisher 9. Then the information could be distributed according to the information in the profiles. The Information Publisher 9 comprises in one embodiment of the invention lists 23,25 comprising the addresses to customers that should be provided with the same information. Here only two lists 23,25 are shown, but there could of course be many more lists present. The customers who want to join the information service must first inform the Information Publisher 9 about for example what kind of information they want to receive. Each list comprises for example all the customers wanting a specific type of information or all the customers who should receive commercials to get free Internet. Another possibility with this system is that the customers formation to be sent to friends or colleagues. In this case the Information Publisher 9 also comprises, or can load down from the customers, another type of lists comprising the different customers' addresses to for example friends and colleagues. The benefits of the method and system according to the invention will be even greater if SIP (= Session Initiation Protocol) is used as the transport protocol between the service provider, the information providers and the customers. When SIP is used the customer can be reached with the information he wants to have even if he is not sitting by his computer. The information could for example be transformed to show up on his mobile telephone. When the customer turns on his mobile terminal the Information Receiver 19 informs the Information Publisher 9 that this customer is connected and which address and type of terminal he is connected to. A new customer who is interested in receiving a certain type of information needs to inform the Information Publisher 9 about what type of information he is interested in receiving. Different customers wanting the same type of information form a group of customers. The Information Publisher keeps lists 23,25 of all these groups. The Information Providers 11,13,15 then just send the information to the Informa- tion Publisher that distributes the information to the customers in the list for this specific information. The Information Receiver in each of these Customer devices receives the information and processes it. Then the information is displayed to the customers. If there are customers in this specific list that not are logged on the information could be queued in the Information Publisher 9 to be sent to the customer as soon as he logs on. In a second embodiment of the invention only a notice about that information has been received and could be displayed is displayed to the customer right away. Then the customer is able to choose if he wants to read the information now or later. There are also other different possibilities of how to display the information to the customer. The displayed mformation could either disappear from the display after a certain time period or needs to be clicked on to disappear. The latter could be preferred if a confirmation that the informa the customer is needed. Another possible embodiment of the invention is that the Information Publisher 9 informs the Information Providers 11,13,15 about the customer profiles and that the Information Providers 11,13,15 themselves distribute the information to the customers. Fig. 2 is a flow chart showing the process for distribution of information according to a first embodiment of the invention. The components that are mentioned in this description of the process are all shown in Fig. 1. The process starts in block B41 where a customer comprised in one of the lists 23,25 connects to the network. Thus the Communication Stack 17 is connecting to the Network Access Server 7 through the first interface II . In block B43 the Information Receiver 19 informs the Information Publisher 9 through the second interface 12 that this specific customer now is logged on. The Information Publisher 9 marks that the customer now is logged on in his lists 23,25. In block B45 one of the Information Providers 11 has new information to deliver. It transfers this informa- tion to the Information Publisher 9. In block B47 the Information Publisher 9 identifies the list comprising the addresses of customers wanting this specific information and delivers the information to the Information Receivers 19 in each concerned Customer device 3 through the second interface 12. In block B49 the information is received and processed in the Information Receivers 19, and in block B51 the In- formation Receivers 19 instruct the Information Presenters 21 to notify the customers with the information and the information is displayed to the customers. In block B53 the Information Receivers 19 check if the mformation has been correctly displayed and return a success message or a fault message to the Information Publisher 9 telling whether the information was displayed correctly to the customer or not. If the information was displayed correctly in the Customer device the process ends in block B55. In another embodiment of the inventio warded in some way when the information has been' displayed. If, on the other hand, the information not could be displayed the process continues in block B57 where the Information Publisher 9 informs the Network Access Server 7 about the failure. In block B59 the Network Access Server 7 takes action. For example the customer could be disconnected if the situation is that the customer is obligated to for example receive commercials in exchange for free Internet. These last steps where a message is sent from the Information Receiver 19 to the Information Publisher 9 telling if the information was displayed or not are not necessary for the invention. Fig. 3 shows a process according to one embodiment of the invention. This process is complementary to the process described in Fig. 2. The first embodiment described in Fig, 2 could thus be extended to comprise also this feature described below. Here the sending of information is initiated from the customer. It could for example be information that has been received by the customer and that he wants to forward to all his colleagues. Otherwise it could be information that has been produced in the Customer device 3. In block B61 a customer sends a message to the Information Publisher 9 containing the information he has received and that he wants to forward to for example his friends or colleagues. The message comprises also addresses to the customers he wants to forward the information to. In block B63 the message is received in the Information Publisher 9 and in block B65 the information is distributed to the other customers. This distribution is done in the same way as the distribution of information from the Information Providers 11,13,15.
