Description
Område for oppfinnelsen. Field of the invention.
Den foreliggende oppfinnelse vedrører et telekommunikasjonssystem i samsvar med innledningen i patentkrav 1. The present invention relates to a telecommunications system in accordance with the introduction in patent claim 1.
Bakgrunn og teknikkens stilling. Background and state of the art.
Innen teknikkens stilling er der forskjellige løs-ninger .med en type av distribuert utførelse og virknings-måte. Noen eksempler er presentert nedenfor. Within the state of the art, there are different solutions with a type of distributed execution and mode of action. Some examples are presented below.
WO, A2, 9531872 beskriver en fremgangsmåte for å utføre computerkrevende applikasjoner på en distribuert måte ved hjelp av en kraftig computer, og deretter vise resultatet på en lokal stasjon. WO, A2, 9531872 describes a method for executing computer-intensive applications in a distributed manner using a powerful computer, and then displaying the result on a local station.
Videre er det beskrevet i dokument WO, Al, 9204670 et system for distribuert aksess til en database som medfører at en nøkkel "hentes" i en fjerncomputer via et modem. Nøkkelen gjør deretter databasen tilgjengelig for brukeren som belastes automatisk. Furthermore, there is described in document WO, Al, 9204670 a system for distributed access to a database which means that a key is "retrieved" from a remote computer via a modem. The key then makes the database available to the user who is charged automatically.
US patent 5.335.276 beskriver et multikommunikasjons-middel hvor applikasjonsprogrammer tilveiebringes fra eksterne datamaskiner. US patent 5,335,276 describes a multi-communication means where application programs are provided from external computers.
WO, Al, 9508900 omhandler et mobilkommunikasjonssystem for tilkobling av en fjerntliggende arbeidsstasjon til et datanettverk via et mobilkommunikasjonsnettverk. WO, Al, 9508900 relates to a mobile communication system for connecting a remote workstation to a computer network via a mobile communication network.
Anvendelse av mobiltelefoner har i løpet av de siste år vokst på en eksplosiv måte. Dette har resultert i at brukerne ønsker å kommunisere via mobile nettverk med større og større applikasjoner. Parallelt med denne ut-vikling har antall brukere som er koplet til det globale datanettverk Internett stadig økt. Det er i dag også mulig å få tilgang til Internett via det mobile telekommunika-sjonsnettverk ved å tilkople en computer til en mobil telefon. Der eksisterer også produkter som tilbyr HTML-presentasjoner på enkle konstruksjoner innebygget i en mobil terminal. Imidlertid vil det oppstå problemer idet utnyttelsen av mer avanserte Internett-baserte applikasjoner som krever store hovedminner, harddisker og kraftige prosessorer. Slike applikasjoner vil det i fremtiden være et enda større behov for. The use of mobile phones has grown explosively in recent years. This has resulted in users wanting to communicate via mobile networks with larger and larger applications. In parallel with this development, the number of users connected to the global computer network Internet has steadily increased. Today, it is also possible to access the Internet via the mobile telecommunications network by connecting a computer to a mobile phone. There are also products that offer HTML presentations on simple structures built into a mobile terminal. However, problems will arise in the utilization of more advanced Internet-based applications that require large main memories, hard drives and powerful processors. There will be an even greater need for such applications in the future.
Samtidig går trenden mot enda mindre, lettere og mer enkle mobilterminaler. Et formål med foreliggende oppfinnelse er derfor å, via en mobiltelefon, tilveiebringe store applikasjoner uten behov for å gjør mobiltelefonene større og mer komplekse. Et annet formål med foreliggende oppfinnelse er å tilveiebringe et konsept som muliggjør små, lette og elektrisitetsbesparende mobile terminaler som allikevel kan tilby avanserte tjenester, så som Java-applikasjoner, sanntidsapplikasjoner, minnekrevende applikasjoner etc, og å forbedre det offentlige tele-kommunikasjonsnettverk med en bedre infrastruktur for abonnentene. At the same time, the trend is towards even smaller, lighter and simpler mobile terminals. One purpose of the present invention is therefore to, via a mobile phone, provide large applications without the need to make the mobile phones larger and more complex. Another object of the present invention is to provide a concept that enables small, light and electricity-saving mobile terminals that can still offer advanced services, such as Java applications, real-time applications, memory-intensive applications, etc., and to improve the public telecommunications network with a better infrastructure for the subscribers.
Den tekniske løsning for de ovenfor angitt problemer er angitt i den karakteriserende del av patentkrav 1, mens foretrukne alternative utførelser er kjennetegnet ved de uselvstendige kravene 2-9. The technical solution for the above-mentioned problems is indicated in the characterizing part of patent claim 1, while preferred alternative embodiments are characterized by the independent claims 2-9.
Et telekommunikasjonssystem i samsvar med oppfinnelsen gjør det mulig å tilby ressurskrevende multimedieapplikasjoner, via en mobil terminal. Den mobile terminal kan være konstruert på en måte som er uavhengig av hvilke applikasjoner som skal tilbys. A telecommunications system in accordance with the invention makes it possible to offer resource-intensive multimedia applications via a mobile terminal. The mobile terminal can be designed in a way that is independent of which applications are to be offered.
En annen fordel med dette konsept er at presentasjonsmåten på den mobile terminal er ganske transparent i forhold til applikasjonene på klient-computerne. Dette resulterer videre i at programvaren som utføres i bruker-computeren kan forandres og oppgraderes uten innblanding av eieren eller brukeren av den mobile terminal. På denne måten kan man, til mobile applikasjonsbrukere, tilby en integrert rekke av applikasjoner som alltid er det siste markedet kan tilby. Another advantage of this concept is that the presentation method on the mobile terminal is quite transparent compared to the applications on the client computers. This further results in the software being executed in the user computer being able to be changed and upgraded without the intervention of the owner or user of the mobile terminal. In this way, mobile application users can be offered an integrated range of applications that are always the latest the market can offer.

I fig. 1 vises konseptet i samsvar med foreliggende oppfinnelse med et antall bruker-computere (KD) som er tilkoplet til et åpent datanettverk, f.eks. Internett. Videre er det vist en mobil terminal (MT) og en distribuert presentasjonsbro (DVB), og likeledes andre nettverks-funksjoner . In fig. 1 shows the concept in accordance with the present invention with a number of user computers (KD) which are connected to an open computer network, e.g. Internet. Furthermore, a mobile terminal (MT) and a distributed presentation bridge (DVB) are shown, as well as other network functions.
I den distribuerte presentasjonsbro er to funksjoner inkludert, som benevnes distribuert presentasjonsfunksjon (DVF) og den distribuerte terminalbehandlingsfunksjon (DTHF), som fungerer som forklart nedenfor. In the distributed presentation bridge, two functions are included, which are called the distributed presentation function (DVF) and the distributed terminal processing function (DTHF), which work as explained below.
I den distribuerte presentasjonsbro (DVB) er en distribuert terminalbehandlingsfunksjon (DTHF) inkludert, og denne har som formål å behandle kommunikasjonen med den mobile terminal (MT). Idet den mobile terminal aktiveres for anvendelse, i samsvar med konseptet ifølge foreliggende oppfinnelse, utføres tilkoplingen av den mobile terminal (MT) og denne etablerer en toveis dataforbindelse til den distribuerte terminalbehandlingsfunksjon (DTHF) via et åpent datanettverk, så som for eksempel Internett. Denne tilkoplingsprosedyre inkluderer nødvendig sikkerhets-kontroll for å garantere identiteten til den mobile terminal (MT). In the distributed presentation bridge (DVB) a distributed terminal processing function (DTHF) is included, the purpose of which is to process the communication with the mobile terminal (MT). As the mobile terminal is activated for use, in accordance with the concept according to the present invention, the connection of the mobile terminal (MT) is carried out and this establishes a two-way data connection to the distributed terminal processing function (DTHF) via an open data network, such as for example the Internet. This connection procedure includes the necessary security check to guarantee the identity of the mobile terminal (MT).
Deretter kan den mobile terminal (MT) signalere til den distribuerte terminalbehandlingsfunksjon (DTHF) via f.eks. tastatur eller mus som er koplet til den mobile terminal. Ved overføring av f.eks. bilder via Internett, overføres disse først til den distribuerte presentasjonsfunksjon (DVF) inkludert i den distribuerte presentasjonsbro, og deretter videre til den distribuerte terminalbe-handlingsf unks jon (DTHF). I (DTHF) komprimeres bildene ved en egnet bildekomprimeringsalgoritme, f.eks. Mpeg eller Mjpeg. De komprimerte bildene overføres deretter til den mobile terminal (MT). Når systemet skal avkoples kan den mobile terminal (MT) spørre om en "avkopling" fra den distribuerte terminalbehandlingsfunksjon (DTHF), som har funksjonalitet for dette, og som deretter bryter forbindelsen mellom den mobile terminal (MT) og den distribuerte terminalbehandlingsfunksjon (DTHF). Then the mobile terminal (MT) can signal to the distributed terminal processing function (DTHF) via e.g. keyboard or mouse connected to the mobile terminal. When transferring e.g. images via the Internet, these are first transferred to the distributed presentation function (DVF) included in the distributed presentation bridge, and then on to the distributed terminal processing function (DTHF). In (DTHF) the images are compressed by a suitable image compression algorithm, e.g. Mpeg or Mjpeg. The compressed images are then transferred to the mobile terminal (MT). When the system is to be disconnected, the mobile terminal (MT) can request a "disconnect" from the distributed terminal handling function (DTHF), which has functionality for this, and which then breaks the connection between the mobile terminal (MT) and the distributed terminal handling function (DTHF) .
De funksjonelle deler som den distribuerte terminal-behandlingsf unks jon (DTHF) inkluderer, er som følger: The functional parts that the distributed terminal processing function (DTHF) includes are as follows:
1) Forbindelse mellom MT og DTHF. 1) Connection between MT and DTHF.
2) Identifisering av MT. 2) Identification of MT.
3) Verifisering av MT. 3) Verification of MT.
4) Komprimering av bilder. 4) Compression of images.
5) Fremsendelse av signaler fra MT til DVF. 5) Transmission of signals from MT to DVF.
6) Avkopling mellom MT og DTHF. 6) Disconnection between MT and DTHF.
Den distribuerte presentasjonsfunksjon (DVF) har som sitt formål å behandle kommunikasjonen med bruker-computerne som utfører programmer på vegne av den mobile terminal (MT). Den distribuerte presentasjonsfunksjon (DVF) fungerer i det hele som en X-server til hvilken bruker-computerne kan tilkoples. Applikasjonsprogrammene utføres dermed i bruker-computerne, men inngangsdata (signaler fra tastatur og mus) og utgangsdata (presentasjon på frem-visningsenhet) behandles av den distribuerte presentasjonsfunksjon (DVF). Hovedforskjellen i forhold til en X-server er at den distribuerte presentasjonsfunksjon (DVF) kun utnytter den mobile terminal (MT) som bildeskjerm, tastatur og mus. Dette utføres via den distribuerte terminalbehandl-ingsf unks jon (DTHF) som behandling kommunikasjonen med den mobile terminal (MT). The distributed presentation function (DVF) has as its purpose to process the communication with the user computers that execute programs on behalf of the mobile terminal (MT). The distributed presentation function (DVF) functions in its entirety as an X server to which the user computers can be connected. The application programs are thus executed in the user computers, but input data (signals from the keyboard and mouse) and output data (presentation on the display unit) are processed by the distributed presentation function (DVF). The main difference compared to an X server is that the distributed presentation function (DVF) only utilizes the mobile terminal (MT) as a screen, keyboard and mouse. This is carried out via the distributed terminal processing function (DTHF) which processes the communication with the mobile terminal (MT).
Den distribuerte presentasjonsfunksjon (DVF) mottar inngangsdata fra den mobile terminal (MT) via den distribuerte terminalbehandlingsfunksjon (DTHF), og fremsender disse til den aktuelle bruker-computer. Den distribuerte presentasjonsfunksjon (DVF) fremsender også utgangsdata fra bruker-computeren til den mobile terminal (MT) via den distribuerte terminalbehandlingsfunksjon (DTHF). The distributed presentation function (DVF) receives input data from the mobile terminal (MT) via the distributed terminal processing function (DTHF), and forwards this to the relevant user computer. The distributed presentation function (DVF) also forwards output data from the user computer to the mobile terminal (MT) via the distributed terminal processing function (DTHF).
Den del som er relatert til sikkerhet i kommunikasjonen med den distribuerte presentasjonsfunksjon (DVF) håndteres av bruker-computerne. Disse computere identifiserer og verifiserer brukeren når han/hun anmoder om en forbindelse via den distribuerte presentasjonsbro (DVB) på samme måte som om den distribuerte presentasjonsbro (DVB) var en ordinær computer tilkoplet til det åpne datanettverk. The part related to security in the communication with the distributed presentation function (DVF) is handled by the user computers. These computers identify and verify the user when he/she requests a connection via the distributed presentation bridge (DVB) in the same way as if the distributed presentation bridge (DVB) were an ordinary computer connected to the open computer network.
Den distribuerte presentasjonsbro (DVB) inkluderer de følgende funksjonsdeler: The distributed presentation bridge (DVB) includes the following functional parts:
1) X-server 1) X server
2) verifisering 2) verification
3) etc. 3) etc.
Systemløsningen medfører at multimedieapplikasjoner som er ressurskrevende kan tilbys via en mobil terminal. Den mobile terminal kan være konstruert på en måte som er uavhengig av hvilke applikasjoner som tilbys. Dette er mulig ved at applikasjonene utføres i klient-computerne tilkoplet til et åpent datanettverk. Funksjonene for den mobile terminal er kun toveis lydkommunikasjon, toveis datakommunikasjon, komprimering av bilder og funksjonsbehandling av bildeskjerm, tastatur og mus. Dette resulterer i at den mobile terminal kan beholdes enkel, men kan likevel tilbys avanserte ressurskrevende multimedietjene-ster. Tjenester som kan tilbys via denne systemløsning eller dette konsept er f.eks. "bestillingsvideo", video-spill, tekstbehandling, tradisjonell og interaktiv TV. The system solution means that resource-intensive multimedia applications can be offered via a mobile terminal. The mobile terminal can be designed in a way that is independent of which applications are offered. This is possible because the applications are executed in the client computers connected to an open computer network. The functions for the mobile terminal are only two-way audio communication, two-way data communication, compression of images and function processing of the image screen, keyboard and mouse. This results in the mobile terminal being kept simple, but advanced resource-demanding multimedia services can still be offered. Services that can be offered via this system solution or this concept are e.g. "video on demand", video games, text processing, traditional and interactive TV.
