Abstract

The method is applied to a mobile telephone (10) which is linked by a telecommunications network (11) to a software-updating computer system (12). The computer system includes a transceiver (121), a volatile memory (123) and a hard disc (124). The mobile telephone holds its software in a non-volatile flash memory (103) with a structure table containing its version number. The software is set into an updating mode and a link is established with the remote computer system, to which the structure table is transmitted. An updating package with new operating system and function modules and a modified structure table is then received by the mobile telephone, via its transceiver (106).

Description

Die Erfindung betrifft ein Verfahren zur Aktualisierung der Software in einem mikrocomputergestützten Telefon gemäß Gat­ tungsbegriff des Patentanspruchs 1.The invention relates to a method for updating the Software in a micro-computer based phone according to Gat term of claim 1.

Die sich rasch entwickelnde Telefontechnik, vor allem Mobiltele­ fontechnik, erfordert eine gelegentliche Aktualisierung der in einem derartigen Telefon gespeicherten Software. Viele Mobilte­ lefonanbieter verlangen von einem Benutzer, daß er zur Aktuali­ sierung der Software sein Mobiltelefon zu einer Kundendienst­ stelle bringt. Dies ist jedoch ziemlich unpraktisch, vor allem wenn sich die Kundendienststelle weit entfernt befindet. Ande­ rerseits ist es auch unbequem für die Kundendienststelle, da sie über Techniker und Ausrüstungen für die Durchführung solcher Ak­ tualisierungen verfügen muß.The rapidly developing telephone technology, especially mobile phones fontechnik, requires an occasional update of the in software stored in such a telephone. Many mobiles Telephone providers require a user to update them software the mobile phone to a customer service job brings. However, this is pretty impractical, especially if the customer service point is far away. Ande on the other hand, it is also inconvenient for the customer service point as it about technicians and equipment for performing such Ak updates must have.

Zur Lösung dieser Probleme wurden bereits verschiedene Aktuali­ sierungstechniken angegeben. Die US-PS 5,418,837 (Johansson et al.) beschreibt ein Verfahren, welches eine SUM-(= Software-Up­ grading-Module-)Karte für derartige Aktualisierungen verwendet. Die SUM-Karte wird von einem SIM-(= Subscriber-Identity-Module-) Kartenleser gelesen, der sich in einigen Mobiltelefonen, wie zum Beispiel GSM-(= Global-System-For-Mobile-Communications-)Termi­ nals, befindet. Obgleich es für den Benutzer damit möglich ist, sein Mobiltelefon mittels der SUM-Karte zu aktualisieren, an­ statt dafür eine Kundendienststelle aufsuchen zu müssen, hat diese Technik doch einige Nachteile. Zunächst verlangt die Be­ schaffung einer korrekten SUM-Karte für seine Bedürfnisse von dem Benutzer Zeit und Mühe. Sodann muß sich der Benutzer, falls die erhaltene SUM-Karte inkorrekt ist oder er seine Optionen für die Aktualisierung seines Mobiltelefons ändert, eine andere SUM-Karte beschaffen, um den Vorgang zu beenden.Various updates have already been made to solve these problems techniques specified. U.S. Patent No. 5,418,837 (Johansson et al.) describes a method which a SUM - (= software up grading module) card used for such updates. The SUM card is from a SIM (= Subscriber Identity Module) Read card reader, which is in some mobile phones, such as Example GSM - (= Global-System-For-Mobile-Communications-) terms nals. Although it is possible for the user to update his mobile phone using the SUM card instead of having to go to a customer service point this technique has some disadvantages. First, the Be Creation of a correct SUM card for his needs the user time and effort. Then the user must, if the SUM card received is incorrect or his options for  the update of his cell phone changes, another one Obtain the SUM card to complete the process.

Eine andere Technik, wie sie in der US-PS 5,430,877 (Naylor) an­ gegeben ist, gestattet es, mittels eines Mobiltelefons ein oder mehrere über eine unmittelbare Partner-zu-Partner-Verbindung da­ mit verbundene weitere Mobiltelefone zu aktualisieren, sofern es selbst eine Software mit höherer Versionsnummer aufweist. Um dieses Verfahren anwenden zu können, muß der Benutzer aber zu­ nächst einmal ein Mobiltelefon finden, welches eine Software mit höherer Versionsnummer hat. Dies ist sehr unpraktisch, wenn ihm kein entsprechender Telefonteilnehmer bekannt ist. Dazu noch müssen sämtliche verbundenen Mobiltelefone miteinander kompati­ bel sein, um das Verfahren anwenden zu können.Another technique such as that described in U.S. Patent No. 5,430,877 (Naylor) is given, allows one or several there via a direct partner-to-partner connection connected to update other connected cell phones, provided it even has software with a higher version number. Around However, the user must be able to use this method next find a mobile phone with software has a higher version number. This is very impractical when it comes to it no corresponding telephone subscriber is known. Plus all connected mobile phones must be compatible with each other to be able to use the procedure.

Auf diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, ein verbessertes Aktualisierungsverfahren für Telefone gemäß Gattungsbegriff des Anspruchs 1 anzugeben, welches den Benutzer einer Mitwirkung hierzu weitgehend entbindet.Against this background, the invention is based on the object according to an improved update procedure for phones Specify the generic term of claim 1, which the user largely relieved of participation in this.

Diese Aufgabe ist erfindungsgemäß durch die Merkmale des Pa­ tentanspruchs 1 gelöst. Die Unteransprüche geben darüberhinaus­ gehend vorteilhafte Ausgestaltungsmöglichkeiten an.This object is achieved by the features of Pa claim 1 solved. The subclaims also give going to advantageous design options.

Das betreffende Verfahren sieht vor, daß das Telefon zunächst eine Telekommunikationsverbindung mit einem Computersystem her­ stellt und dem Computersystem eine Strukturtabelle übermittelt. Das Computersystem erstellt daraufhin ein Aktualisierungspaket entsprechend der empfangenen Strukturtabelle und überträgt die­ ses zurück zu dem Telefon. Das Aktualisierungspaket findet dort dazu Verwendung, die Software des Telefons zu aktualisieren, wo­ bei es zunächst noch zwecks Prüfung in einem Speicher des Tele­ fons zwischengespeichert werden kann.The procedure in question provides that the phone first establishes a telecommunications connection with a computer system provides and transmits a structure table to the computer system. The computer system then creates an update package according to the received structure table and transmits the ses back to the phone. The update package takes place there to use to update the phone's software where at first still for the purpose of testing in a memory of the tele fons can be cached.

Nachfolgend wird ein bevorzugtes Ausführungsbeispiel anhand der Zeichnungen genauer beschrieben. Dabei zeigtA preferred exemplary embodiment is described below with reference to FIG Drawings described in more detail. It shows

Gemäß Fig. 1 ist mit einem Mobiltelefon 10 über ein Telekommuni­ kationsnetz 11 ein Computersystem 12 verbunden. Das Telekom­ munikationsnetz 11 ist ein Mobiltelefonnetz. Das Mobiltelefon 10 enthält eine Zentralprozessoreinheit (CPU) 101, eine Anzeige­ einheit 102 zur Anzeige einfacher Mitteilungen an den Benutzer des Telefons 10, einen nichtflüchtigen Speicher 103, wie er bei­ spielsweise unter der Bezeichnung FLASH EPROM bekannt ist, zur Softwarespeicherung für die Zentralprozessoreinheit 101, einen flüchtigen Speicher 104, wie zum Beispiel einen Speicher für wahlfreien Zugriff (RAN), für die Ausführung des in der Software enthaltenen Programms oder für die Aktualisierung der Software, ein Tastenfeld 105 zur Eingabe von Telefonnummern oder Steuer­ codes seitens des Benutzers, eine Sende-/Empfangs-Einheit 106 für die Kommunikation mit dem Telekommunikationsnetz 11 sowie einen von der Zentralprozessoreinheit 101 steuerbaren Haupt­ schalter 107.According to Fig. 1 is provided with a mobile phone 10 via a telecommuni cations network 11, a computer system 12 is connected. The telecommunications network 11 is a mobile phone network. The mobile phone 10 contains a central processor unit (CPU) 101 , a display unit 102 for displaying simple messages to the user of the telephone 10 , a non-volatile memory 103 , as is known for example under the name FLASH EPROM, for software storage for the central processor unit 101 , a volatile memory 104 , such as a random access memory (RAN), for executing the program contained in the software or for updating the software, a keypad 105 for entering telephone numbers or control codes on the part of the user, a transmission / Receive unit 106 for communication with the telecommunications network 11 and a main switch 107 controllable by the central processor unit 101 .

Das Computersystem 12 ist zwecks Softwareaktualisierung an das Telekommunikationsnetz 11 angeschlossen. Es enthält eine Sende-/ Empfangs-Einheit 121 für die Kommunikation mit dem Netz 11, eine Zentralprozessoreinheit (CPU) 122 sowie, damit verbunden, einen flüchtigen Speicher 123 und eine Festplatte 124 zur Abwicklung des Aktualisierungsvorganges. The computer system 12 is connected to the telecommunications network 11 for software updates. It contains a transceiver unit 121 for communication with the network 11 , a central processor unit (CPU) 122 and, connected to it, a volatile memory 123 and a hard disk 124 for handling the update process.

Fig. 2 zeigt schematisch die in dem nichtflüchtigen Speicher 103 des Mobiltelefons 10 gespeicherte Software 20. Die Software 20 enthält mehrere Module wie zum Beispiel den OS-(= Operating- System-)Modul 21, Funktionsmodule 22 und eine Strukturtabelle 23. Die Funktionsmodule 22 enthalten Kommunikationsmodule für die Kommunikation mit Basisstationen des Telefonnetzes 11 ver­ mittels eines von einem bestimmten Mobiltelefonnetz, wie zum Beispiel einem GSM-Netz, definierten Protokolls und ebenso spe­ zielle Programmodule (feature moduls) für die Durchführung be­ stimmter Funktionen oder Programmpunkte an einem bestimmten Te­ lefon 10, wie zum Beispiel eine Kurzansage, eine Anrufbeantwor­ tungsfunktion und dergl. Der OS-Modul 21 bildet ein Realzeit-Be­ triebssystem für die Steuerung der Operationen aller Module 22 und ebenso für die Aktualisierung der Software 20. Er kann in einen Aktualisierungsmodus umgeschaltet werden für die Aktuali­ sierung sämtlicher Module der Software 20. Fig. 2 schematically shows the information stored in the nonvolatile memory 103 of mobile phone 10 software 20. The software 20 contains several modules, such as the OS (= operating system) module 21 , function modules 22 and a structure table 23 . The function modules 22 contain communication modules for communication with base stations of the telephone network 11 ver by means of a protocol defined by a specific mobile telephone network, such as a GSM network, and likewise special program modules (feature modules) for carrying out certain functions or program points on one certain phone 10 , such as a short announcement, an answering machine function and the like. The OS module 21 forms a real-time operating system for controlling the operations of all modules 22 and also for updating the software 20 . It can be switched to an update mode for updating all modules of software 20 .

Die Strukturtabelle 23 enthält die gesamte Strukturinformation der Software 20, wie zum Beispiel die Versionsnummer der Soft­ ware 20 und des OS-Moduls 21, die Versionsnummer und spezielle Parameter eines jeden Funktionsmoduls 22, die Hardwarestruktur­ daten des Telefons 10, wie zum Beispiel die Speichergröße und die Art der Zentralprozessoreinheit 101, des Tastenfelds 105 und der Anzeigeeinheit 102. Diese Strukturtabelle 23 wird an das Computersystem 12 übertragen zur Festlegung dessen, wie die Software 20 zu aktualisieren ist. Die in der Strukturtabelle 23 enthaltene Informationen können je nach der Art des von dem Com­ putersystem 12 gebotenen Aktualisierungsdienstes verändert wer­ den.The structure of Table 23 contains the entire structural information of the software 20 such as software version number of the soft 20 and the OS module 21, the version number and specific parameters of each functional module 22, the hardware structure of data of the telephone 10, such as the memory size, and the type of the central processor unit 101 , the keypad 105 and the display unit 102 . This structure table 23 is transmitted to the computer system 12 to determine how the software 20 is to be updated. The information contained in the structure table 23 can be changed depending on the type of update service offered by the computer system 12 .

Der Speicherzuordnungsplan nach Fig. 3 zeigt, in welcher Weise die Module 21 und 22 in dem nichtflüchtigen Speicher 103 gespei­ chert sind. Jeder der Module 21, 22 und 23 ist in einem eigenen Speicherschlitz 31 des Speichers 103 gespeichert, wobei ihm je­ weils ein gewisser zusätzlicher Speicherraum für die spätere Ak­ tualisierung zugeordnet ist. Eine Adressentabelle, die einen Teil der Strukturtabelle 23 bildet, dient dazu, die Adressen der vorbestimmten Speicherschlitze 31 festzuhalten. Bei der Aktuali­ sierung eines vorhandenen Moduls wird in dem gleichen Speicher­ schlitz ein neuer Modul abgespeichert, wobei mit derselben An­ fangsadresse begonnen wird. Da ein jeder Speicherschlitz 31 zu­ sätzlichen Speicherraum aufweist, bildet eine Größenabweichung des neuen Moduls kein Problem, solange dessen Größe nicht über den verfügbaren Speicherraum des betreffenden Speicherschlitzes 31 hinausgeht.The memory allocation plan of Fig. 3 in what way shows the modules 21 and 22, in the nonvolatile memory 103 are chert vomit. Each of the modules 21 , 22 and 23 is stored in its own memory slot 31 of the memory 103 , with a certain additional memory space being assigned to it for later updates. An address table, which forms part of the structure table 23 , serves to record the addresses of the predetermined memory slots 31 . When an existing module is updated, a new module is saved in the same memory slot, starting with the same starting address. Since each memory slot 31 has additional memory space, a size deviation of the new module is not a problem as long as its size does not exceed the available memory space of the memory slot 31 in question.

Diese Speicherweise gestattet es, einen jeden vorhandenen Modul getrennt zu aktualisieren,und vermeidet so eine komplizierte Speicherordnung oder Speicherumordnungsprobleme in dem Speicher 103. Entsprechend kann der OS-Modul 21 verhältnismäßig einfach sein. Des weiteren wird für die Aktualisierung der gesamten Software 20 kein großer flüchtiger Speicher 104 benötigt, da ja jeweils nur wenige Module zu aktualisieren sein werden. Für die meisten Aktualisierungsvorgänge wird es genügen, wenn der Spei­ cher 104 groß genug ist, drei bis fünf Module aufzunehmen. Dane­ ben ist die Zeit für die Modulübertagung vom Computersystem 12 zu dem Telefon 10 gering.This type of storage allows each existing module to be updated separately, thus avoiding complicated memory ordering or memory reordering problems in memory 103 . Accordingly, the OS module 21 can be relatively simple. Furthermore, no large volatile memory 104 is required for updating the entire software 20 , since only a few modules will have to be updated in each case. For most updates, it will suffice if the memory 104 is large enough to hold three to five modules. Dane ben is the time for module transfer from the computer system 12 to the phone 10 is short.

Fig. 4 gibt einen Aktualisierungsvorgang 40 für die Aktualisie­ rung der Software 20 des Mobiltelefons 10 wieder, der vom Be­ nutzer des Telefons 10 ausgelöst wird. Der Aktualisierungsvor­ gang 40 weist folgende Schritte auf:
Schritt 401 Versetzen des OS-Moduls 21 der Software 20 in einen Aktualisierungsmodus
Schritt 402 Eintasten der Telefonnummer des Computersystems 12 zur Herstellung einer Telekommunikationsverbindung mit dem Computersystem 12 über das Telekommunika­ tionsnetz 11; ist das Netz 11 ein GSM-Netz für die Inanspruchnahme eines Datendienstes seitens einer nahegelegenen Basisstation des Netzes 11, die dar­ aufhin zwischen Telefon 10 und Computersystem 12 eine Folgeinformation in Gestalt digitaler Daten überträgt, so erfolgt seitens des OS-Moduls 21 ein Datenabruf
Schritt 403 den Benutzer einen Optionscode zur Angabe einer Aktualisierungsoption eingeben lassen
Schritt 404 Übertragen der Strukturtabelle 23 und (sofern ein­ gegeben) des Benutzeroptionscodes an das Computer­ system 12
Schritt 405 auf den Empfang der Strukturtabelle 23 aus dem Te­ lefon 10 hin erstellt das Computersystem 12 ein Aktualisierungspaket mit neuen Modulen und einer neuen Strukturtabelle und überträgt diese an das Telefon 10
Schritt 406 Speichern des Aktualisierungspakets in dem flüch­ tigen Speicher 104
Schritt 407 Prüfen des empfangenen Aktualisierungspakets
Schritt 408 Sperren des Hauptschalters 107 zur Verhinderung einer Unterbrechung durch den Benutzer während des folgenden Aktualisierungsschrittes (die dabei sowohl die Software 20 als auch das in dem flüch­ tigen Speicher 104 gespeicherte Aktualisierungspa­ ket zerstören könnte)
Schritt 409 Aktualisieren der Software 20 durch Abspeichern der neuen Module und der neuen Strukturtabelle aus dem Aktualisierungspaket in den einzelnen entsprechen­ den Speicherschlitzen 31
Schritt 410 Freigeben des Hauptschalters 107. Fig. 4 shows an update process 40 for updating the software 20 of the mobile phone 10 again, which is triggered by the user of the phone 10 . The update process 40 has the following steps:
Step 401 Put the OS module 21 of the software 20 in an update mode
Step 402 key in the telephone number of the computer system 12 to establish a telecommunication connection with the computer system 12 via the telecommunications network 11 ; If the network 11 is a GSM network for the use of a data service on the part of a nearby base station of the network 11 , which then transmits subsequent information in the form of digital data between the telephone 10 and the computer system 12 , the OS module 21 retrieves data
Step 403 have the user enter an option code to specify an update option
Step 404 transfer of the structure table 23 and (if given) the user option code to the computer system 12
In step 405 upon receipt of the structure table 23 from the telephone 10 , the computer system 12 creates an update package with new modules and a new structure table and transmits these to the telephone 10
Step 406 store the update package in volatile memory 104
Step 407 check the update packet received
Step 408 lock main switch 107 to prevent user interruption during the subsequent update step (which could destroy both software 20 and the update package stored in volatile memory 104 )
Step 409 updating the software 20 by storing the new modules and the new structure table from the update package in the individual correspond to the memory slots 31
Step 410 release the main switch 107 .
