PROCEDURE AND SYSTEM FOR CONTROL OF SERVICES IN A DATA COMMUNICATION NETWORK

Abstract: A network portal has a so called "roaming function" which identifies the place where the user is and loads home local information adapted to the user's profile of interest. This means that when log-in is made in another place than where the home server is, the portal is adapted to the at present current local network.

Description: PROC EDURE AND SYSTEM FOR CONTROL OFSERVICES INADATA COMMUNICATIONNETWORK TECHNICAL FIELD The present invention relates to a procedure and a system for control of and provision of services to users of terminals connected to data communication networks. BACKGROUND In the future it will be possible for a lot of people to, by means of their personal computers and different types of portable terminals, set up connections to a local broadband network, for instance a city network. The users frequently get into contact with resources in such networks via so called portals. Portals can be regarded as user interfaces which direct and refer to different services in servers which are on local networks and other, larger networks, and which can be used by the persons who have Internet subscriptions at an Internet operator. Today it is a problem to automatically adapt and add services in en existing portal for the geographical location where a user is. At set up of connection in another city/local network than the one that is normally used, for instance from the home, there today do not exist any mechanisms to automatically offer the same broadband services from the at the time being nearest local server, as those from the home server in the home network. DESCRITPTION OF THE INVENTION One aim of the present invention is to meet above indicated problem. This is achieved according to a method as claimed in patent claim 1, and a system as claimed in patent claim A broadband local network in each community/city and a network with nation-wide coverage is utilized. The portal has a so called "roaming function" which identifies the place where the user is and loads home local information adapted to the user's profile of interest. This means that when login is made in another locality than where the home server is, the portal is adapted to the at the time being current local network. Information specific for the locality then automatically turns up in the portal from a local server. This means, for instance, that a virtual "video shop" which is located on a server at the locality where login last was made, is exchanged for a video shop which is located on the local network where the new login has been made. The user can in the example then benefit in full from being connected on a broadband local network. In the same way all for the locality specific information is updated in the portal. It means a big advantage to the user if he/she has a portal which in this way is upgraded automatically with information related to the locality. To the user this means that as long as he/she utilizes material which is on the broadband local network, irrespective of where he/she is, the waiting time and the delays which otherwise are innumerable at "surfing" on the Internet are avoided. The user still has access to the home network and his/her home server. In those cases where the terminal is of mobile type, the base stations shall, at handover of terminals, also check if the terminal is moving from a local network to another. If that is the case, the portal shall, in the same way as for a stationary terminal, be modified and adapted to the new local network. The added value of having a "roaming" portal and a thorough service offer on the local network servers result in, as a consequence, that for instance network providers have greater possibility to establish connections with and keep customers, content providers and other Internet participants . BRIEF DESCRIPTION OF THE FIGURES Figure 1 shows a schematic illustration of a system according to the present invention. Figure 2 shows schematically an illustration of a service portal . Figure 3 shows schematically an illustration of a change of a service portal at roaming. PREFERRED EMBODIMENTS A system in which the present invention with advantage is implemented is shown in Figure 1. To a network 100 is connected a number of units of which only four are shown. It is well within the knowledge of the expert that a network of this type can include generally speaking an unlimited number of units. The units communicate, for instance, by means of known and standardized technology according to the IP-protocol. To the network 100 is connected a user terminal 101 on the screen of which is illustrated in a very schematic way a portal 102. The showing of the portal 102 is preferably made by means of known software technique as, for instance, WebCrawler. Further, a number of servers are connected: A home server 103, a local server 104 and a roaming server 105, which all include functions that will be discussed in more details below. The Portal The portal 102 is a user interface towards the servers which are on the network 100, and which can be used by the users who, for instance, holds Internet subscriptions at Internet providers . The portal, in the following called MyLocalPortal, and which is shown schematically in Figure 2, might look like and function according to the following: MyLocalPortal consists of a number of optional services as, for instance, MyCity 201, MyHome 202, MyLeisureTime 203, MyFriends/MyFamily 204, MyCar 206, My ork 207, which are strongly focused on a certain field. Besides there are services as well which can supplement the others, for instance MyServices 205 and MyNews 208 connected to respective focus field. PLING 209 illustrates a notification about an event the user is to watch. An adaptation to the information profile, the personal portal profile, which the user has selected is also made, he/she can for instance have selected to filter away all sport information, that he/she only wants 8 "pie chart pieces" in the portal, that the "Pling" shall only twinkle and not sound, etc. Roaming Roaming is illustrated in Figure 3. Roaming causes that the portal 102 adapts to and is updated with information for the local network or the place/locality where login has been made, however with regard to what the user has determined in his/her personal portal profile. The adaptation is also based on the quality of the connection of the terminal to the network 100. This means that certain services in the portal will be added/removed, others are changed regarding the content. This means that, irrespective of where the customer connects, he/she will automatically have access to the broadband services which are there, for instance video and music. In addition he/she will have local information about current locality or city without need to search. The services which are of more personal kind are of course included as they are, for instance such services as calendar and address book. Figure 3 illustrates schematically that the updating is made only for the relevant parts of the portal. MyCity 201 is replaced by MyCity-information 308 of the new place, and in the same way for the services MyHome 202, 309, MyLeisureTime 203, 305, MyCar 206, 306 and MyNews 208, 307. The updating of the portal will be rapid because no big amount of data is transmitted to the terminal application when the portal is updated, but only web links, network references and meta information about the information content of the local server. This in its turn results in that the terminal application itself can filter away, in addition to what the personal portal profile already has filtered, links which it cannot handle, for instance video flows with too large bandwidth or, in the case WAP, only the WAP-adapted services that are to be derived, are shown. The selection of which server that shall be appointed to be local server 104 is made in a roaming server 105 on basis of IP-number, mobile base station identity or calling subscriber number. The roaming server 105 uses databases which map said identities for terminals, home servers 103, local servers 104, OLL-boxes, GSM/UMTS base stations, etc. to geographical position. The terminal application also can, if it has connection to any other positioning system, for instance GPS, GSM- positioning, user-input position etc, transfer this to the roaming server. The case user - stationary terminal The scenario is that a user wants to get access to his/her portal from a stationary terminal 101 in, for instance, a library, in a provision-shop or at a place of work. The user clicks on an icon/button, MyPortal. An HTTP-call is directed to a central roaming server 105 in the network after approved authentication, for instance via traditional input of user name and password, or use of a new technique such as smart card, fingerprints etc. The roaming server 105 gives an HTTP-response to the application with references to the local server 104 and the home server 103. The mapping towards which server that shall be appointed to be local server 104 is made in the roaming server 105, on basis of the IP-number of the stationary terminal 101. In the database of the roaming server, there are IP-numbers for clients, home servers and local servers related to geographical position. The portal application then derives both the user's locality profile for the home locality and personal portal profile from the home server. From the local server is derived the for the current locality specific locality profile (unfiltered with regard to personal portal profile) . The application then compares the two locality profiles and filters the content on basis of the personal portal profile. The user portal is presented, finally, updated with the services and the offer which is on the local server 104 on the locality where the user is. If the roaming server 105 does not succeed in locating via the IP-number database, the application in a dialog square asks the user to indicate where he/she is at present. In a roaming database this information is stored in order to provide suitable suggestions for locality for other users who connect from the same network. By that, the knowledge of the roaming database is successively improved about (probable) localities for different IP subnetworks. In other respects this means no difference compared with the scenario above. The case user - semi-stationary terminal The scenario is that a user wants to get access to his/her portal from a semi-stationary terminal 101, for instance a portable computer which for the time being is connected by Ethernet on a place of work. The scenario reminds a lot of the case user - stationary terminal which has been described above. In this case the user gets access to a temporary IP-number from an IP-number pool in the company network where he/she is. The allocation of IP-numbers is made either manually or via any automatic protocol, for instance DHCP, Dynamic Host Configuration Protocol. The mapping towards which server that shall be appointed to be local server 104 then is made in the same way as above with regard to the database in the roaming server 105, on basis of the IP-number of the company network. Authentication, deriving of home locality profile and personal portal profile, updating with information from the local server 104, etc is after that made as in the case user - stationary terminal described above. The case user - called circuit connection The scenario is that a user wants to get access to his/her portal with a called circuit connection to the network. In the network the calling modems are connected to a so called OLL-box which handles login and debiting. The OLL-box even today controls calling subscriber numbers (A-numbers) . To make the roaming function functioning, the OLL-box is updated so that it also listens to HTTP-calls. One solution to make the OLL-box listen to and filter HTTP-traffic is so called transparent proxy. If a call coming in to www.myportal.se (which is going to the roaming server 105) , the "OLL-box" adds the subscriber number in the call. For instance http://www-myportal.se can with addition be http : //www-myportal . se?subscribernumber =####-#####, where the #-symbols represent the digits in a telephone number. The roaming server 105 then maps the subscriber number towards geographical location and determines local server 104. Authentication, deriving of home locality profile and personal portal profile, updating with information from the local server 104 etc, is after that made in the same way as in the case user - stationary terminal which has been discussed above. The case user - mobile terminal The scenario is that a user wants to get access to his/her portal from a mobile terminal, for instance GSM or, in the future, for instance UMTS. In this case the position of the mobile is known by the roaming server 105 by the data which exist about base station location. At handover in the mobile system (not shown in the figures) the roaming server 105 is updated with the new position for base station in question. The OLL-box checks, as has been mentioned, already today calling subscriber numbers. In the same way as in the previous case, the OLL-box shall add the subscriber number in the HTTP-calls to www.myportal.se which it has been updated to listen to. If the OLL-box can be updated so that it also gets information about base station ID of the base station to which the mobile is connected, also this identity is added in the HTTP-call. If the OLL-box cannot get base station ID, the roaming server 105 uses the subscriber number to make an enquiry to the traffic management database of the GSM/UMTS-system and by that get knowledge of the geographical position of the mobile. If more exact location is wanted than only with which base station the mobile has contact, this can be achieved by, for instance, GSM-positioning or via GPS. Authentication, deriving of home locality profile and personal portal profile, updating with information from the local server 104, etc, is after that made in the same way as in the case user - stationary terminal described above. Description of the services Below are described examples of what the different services in the portal may contain. A lot of the examples of new services which are presented are based on that the portal also is possible to use at a mobile terminal. At present, WAP-terminals, alternatively PDAs, are probable candidates for this application. New technology, UMTS in the first place, combined with new terminals will make possible the ideas which are described below in a not too far distant future . "PLING" means that a sound is heard and/or a twinkling lamp is lighted in the middle of the portal which informs about that something has happened, for instance that the user has got a mail, somebody is searching for him/her, or a notification of an event the user has asked to be watched. There also should be possibility for the user to in a simple way himself/herself adapt his/her portal, for instance to add new services and to select a personal style in form of colors or background patterns. MyHome Under the service MyHome there may be functions for control and supervision, for instance video supervision of the home. It should be possible to switch on the sauna when traveling home, increase the heating of the home, switch on and switch off lamps, surveil one's home by video cameras and sensors which detect changes etc. Different types of alarm functions should be included for both internal and external damage, i.e. burglary and water leaks. MyCity The service MyCity contains information and offers from the municipality and the local trade and industry. In addition different types of services can be offered which can be used in a simple way in the geographical neighborhood where the user is just at the time being. MyLeisureTime The pie chart piece "MyLeisureTime" can contain for instance music, video and multi-user games within a city/district which can be regarded as a hybrid between the real and the virtual world. The user shall have possibility to get game information (for instance clues, information) to a mobile terminal depending on where in the physical reality he/she is, i.e. a virtual information layer is laid on top of the physical reality of the game. The local operator's broadband network makes it possible to get very high quality of the material that is transferred, when it is distributed within the geographical vicinity, for instance a city. MyWork Under the service MyWork there are services which makes it easy for the user always to get access to documents, e- mail, fax, messages, calendar and have possibility to get notifications/reminders. The user shall in this way be able to in an easy way work from home. The user shall have possibility to, in a simple way, see which of his/her workmates that are online ( ICQ-similar) , have possibility to, in a simple way, set up video conferences with those at home, and share virtual work surfaces. MyCar Under the service MyCar there are among other things different types of control functions. One example is that the user shall able to remotely start engine heater or timer for engine heater. MyFriends/MyFamily Under the service MyFriends/MyFamily is located all addresses, telephone numbers, fax numbers, E-mail addresses etc that the user needs. Functions such as group-pling, i.e. a question is transmitted to a plurality of persons shall exist, and the possibility to rapidly set up video conferences . MyNews Under the pie chart piece "MyNews" the user shall have access to TV, radio, the newspaper and other news that shall be watched. The user shall have possibility to study the news whenever he/she wants. He/she also shall have access to an archive with news that can be searched from, for instance, local TV and radio, i.e. the user shall be able to search among both video, radio and text material. It shall be possible for the user to get access to this both when he/she is out traveling, and when he/she is at home . MyOtherServices MyOtherServices includes all other types of services the user can get access to via his/her portal. MyMoney gives the user on the one hand possibility to mobile shopping, on the other to pay for different types of services he/she utilizes as, for instance, VoD and music. The local bank office can in a simple way be accessed from the portal. MyPersonalStoringPlace where the user shall have possibility to store his/her photographs, videos etc, and in a simple way have possibility to access and show, independent of place and terminal. Under MyOtherServices a user also can select to get tailored offers, MyOffers, from businessmen and advertisers.
