Am Markt sind seit längerer Zeit Dualband-Mobilfunkendgeräte erhältlich, die z.B. den GSM 900- sowie den GSM 1800/1900- Frequenzbereich abdecken. Dies hat den Vorteil, daß damit man wahlweise im GSM 900- oder GSM 1800/1900- Frequenzbereich telefonieren kann, je nach Verfügbarkeit der Netzversorgung in diesen Frequenzbereichen. Voraussetzung dafür ist, daß der Teilnehmer eine entsprechende Subskription für diese Frequenzbänder hat. Mit dem in der Entwicklung befindlichen UMTS-Standard sind wesentlich höherer Datenübertragungsraten vorgesehen, so daß in Zukunft die komfortable Nutzung von Internetdiensten möglich wird.Dual-band mobile terminals have been available on the market for some time, for example cover the GSM 900 and the GSM 1800/1900 frequency range. This has the advantage that you can make calls in the GSM 900 or GSM 1800/1900 frequency range, depending on the availability of the network supply in these frequency ranges. The prerequisite for this is that the subscriber has a corresponding subscription for these frequency bands. The UMTS standard, which is currently being developed, provides for significantly higher data transmission rates, so that convenient use of Internet services will be possible in the future.
Je nach Dienst, wie Telefonie, Fax, Internet, etc., kann die Wahl des einen oder anderen Frequenzbandes die bessere Lösung darstellen. Dies hängt natürlich von der Verfügbarkeit der jeweiligen Frequenzbänder ab.Depending on the service, such as telephony, fax, Internet, etc., the choice of one or the other frequency band can be the better solution. Of course, this depends on the availability of the respective frequency bands.
Die Aufgabe der Erfindung liegt darin, ein Verfahren zum Betrieb eines Dual- oder Mehrband-Mobilfunkendgeräts sowie ein geeignetes Mobilfunkendgerat vorzuschlagen, das dem Teilnehmer je nach angewähltem Dienst eine bestmögliche Dienstequalität bietet. Die Lösung der Aufgabe erfolgt erfindungsgemäß durch die Merkmale der unabhängigen Patentansprüche.The object of the invention is to propose a method for operating a dual- or multi-band mobile radio terminal as well as a suitable mobile radio terminal which offers the subscriber the best possible service quality depending on the service selected. The object is achieved according to the invention by the features of the independent claims.
Der Kern der Erfindung liegt in einer Analyse der vom Benutzer eingegebenen Informationen betreffend die Art des angeforderten Dienstes. Anhand dieser Analyse wird vom Endgerät vorzugsweise automatisch ein Frequenzband ausgewählt, welches den Dienst nach vorgebbaren Kriterien am besten unterstützt. Dazu weist das Mobilfunkendgerat Mittel zur Analyse der Eingabeinformation betreffend die Art des angeforderten Dienstes auf und Mittel zur Auswahl eines geeigneten, verfügbaren Frequenzbandes.The essence of the invention lies in an analysis of the information entered by the user regarding the type of service requested. On the basis of this analysis, the terminal device preferably automatically selects a frequency band that best supports the service according to predefinable criteria. For this purpose, the mobile radio terminal has means for analyzing the input information relating to the type of service requested and means for selecting a suitable, available frequency band.
Die Kriterien zur Auswahl des Frequenzbandes können vom Teilnehmer festgelegt werden. Z.B. kann das verwendete Frequenzband nach dem Kriterium der für den Dienst erforderlichen Datenübertragungsrate ausgewählt werden. Ein anderes Kriterium kann der aktuell günstigste Tarif für den ausgewählten Dienst darstellen. Es ist auch denkbar das Frequenzband nach dem Kriterium der bestmöglichen Verfügbarkeit der Netzversorgung auszuwählen. Diese Kriterien können einzeln als auch in Kombination angewandt werden und sind vom Teilnehmer jederzeit änderbar.The criteria for selecting the frequency band can be defined by the participant. For example, the frequency band used can be selected according to the criterion of the data transmission rate required for the service. Another criterion can be the currently cheapest tariff for the selected service. It is also conceivable to select the frequency band according to the criterion of the best possible availability of the network supply. These criteria can be used individually or in combination and can be changed by the participant at any time.
Die Auswahl des geeigneten Frequenzbandes erfolgt vorzugsweise vollautomatisch durch das Mobilfunkendgerat. Es kann jedoch vorgesehen sein, daß zunächst eine Liste geeigneter Frequenzbänder auf dem Display des Mobilfunkgerätes angezeigt wird, und die Auswahl des zu verwendenden Frequenzbandes letztlich durch den Mobilfunkteilnehmer erfolgt.The suitable frequency band is preferably selected fully automatically by the mobile radio terminal. However, it can be provided that a list of suitable frequency bands is initially shown on the display of the mobile radio device, and the selection of the frequency band to be used is ultimately carried out by the mobile radio subscriber.
Die Art des angeforderten Dienstes wird vom Endgerät durch die Eingabeinformationen des Benutzers erkannt. Dies können die Eingabe einer Rufnummer, die Eingabe eines Codes oder eine direkte Auswahl eines Dienstes sein. Das Endgerät umfasst mindestens zwei Funkmodule zum Betrieb im GSM 900-, GSM 1800/1900- und/oder UMTS-Frequenzbereich. Die Nutzung anderer Frequenzbänder, wie DECT oder AMPS, ADC und JDC, wie sie in den USA und Japan verbreitet sind, ist nicht ausgeschlossen.The type of the requested service is recognized by the end device through the input information of the user. This can be entering a phone number, entering a code or directly selecting a service. The terminal comprises at least two radio modules for operation in the GSM 900, GSM 1800/1900 and / or UMTS frequency range. The use of other frequency bands, such as DECT or AMPS, ADC and JDC, as are common in the USA and Japan, is not excluded.
Das Mobilfunkendgerat beinhaltet eine Softwareapplikation zur Analyse der Eingabeinformation und Auswahl des geeigneten Frequenzbandes.The mobile radio terminal contains a software application for analyzing the input information and selecting the suitable frequency band.
Die Erfindung wird nachfolgend anhand eines Beispiels näher erläutert.The invention is explained in more detail below using an example.
Die Hardware- und Softwarearchitektur eines Mobilfunkendgerat umfasst vorzugsweise folgende Komponenten:The hardware and software architecture of a mobile radio terminal preferably comprises the following components:
1) Ein Eingabemedium, z.B. Tastatur,1) An input medium, e.g. Keyboard,
2) Eine Softwareapplikation zur Analyse der Eingabeinformation2) A software application for analyzing the input information
3) Mehrere Radio (Funk) Module oder ein Kombichip (einschließlich Signalverarbeitung) für verschiedene Frequenzbänder z.B.3) Several radio (radio) modules or a combination chip (including signal processing) for different frequency bands e.g.
1 Modul für GSM 9001 module for GSM 900
1 Modul für GSM 1800/19001 module for GSM 1800/1900
1 Modul für UMTS1 module for UMTS
Durch Analyse der vom Benutzer eingegebenen Informationen wird ein Funkmodul ausgewählt, welches den gewünschten Dienst, der z.B. gekennzeichnet ist durch die eingegebene Rufnummer, einen eingegebenen Code oder die direkte Auswahl eines Dienstes im Menü des Endgerätes, am besten unterstützt.By analyzing the information entered by the user, a radio module is selected that contains the desired service, e.g. is best supported by the phone number entered, a code entered or the direct selection of a service in the menu of the terminal.
Das heißt, wenn der Nutzer z.B. durch Eingabe einer Telefonnummer ein Gespräch aufbauen möchte, analysiert das Endgerät die zur Verfügung stehenden Frequenzbänder und wählt das Band, bei dem die Anforderungen an die Dienstequalität (Quality of Service: QoS) für Telefonie erfüllt sind (z.B. GSM 900). Voraussetzung ist natürlich, daß der Teilnehmer die entsprechenden Subskriptionen für die Frequenzbänder hat. Dabei können weitere Kriterien bei der Auswahl des Frequenzbandes berücksichtigt werden, wie z.B. preislich günstigstes Frequenzband etc.This means that if the user wants to set up a call by entering a telephone number, for example, the end device analyzes the available frequency bands and selects the band in which the quality of service (QoS) requirements for telephony are met (e.g. GSM 900). The prerequisite is, of course, that the subscriber has the appropriate subscriptions for the frequency bands. Further criteria can be taken into account when selecting the frequency band, such as the cheapest frequency band etc.
Wählt der Nutzer über z.B. eine WAP (Wireless Application Protocol) Applikation einen Dienst, der eine höhere Übertragungsrate erfordert als GSM 900 bietet, d.h. eine Bitrate über 9,6 kBit/s, und/oder eine IP Verbindung, sucht das Endgerät das passende Frequenzband z.B. GSM 1800 mit dem General Paket Radio Service für den Verbindungsaufbau. Wird eine noch höhere Datenraten durch die Applikation gefordert, erfolgt ein Wechsel in das UMTS-Frequenzband mit z.B. einer Datenraten bis 384 kBit/s. Das heißt, möchte der Nutzer einen Dienst gekennzeichnet durch eine Applikation auf Basis einer Datenverbindung nutzen, und er ist im Versorgungsbereich mehrerer Frequenzbänder, dann soll das Funkmodul mit dem passenden Dienst und dem besten Quality of Service in diesem Frequenzband angesprochen werden.If the user selects e.g. a WAP (Wireless Application Protocol) application a service that requires a higher transmission rate than GSM 900, i.e. a bit rate over 9.6 kbit / s, and / or an IP connection, the terminal searches for the appropriate frequency band e.g. GSM 1800 with the General Paket Radio Service for establishing a connection. If the application demands an even higher data rate, the UMTS frequency band is changed with e.g. a data rate of up to 384 kbit / s. This means that if the user wants to use a service characterized by an application based on a data connection and he is in the coverage area of several frequency bands, then the radio module should be addressed with the appropriate service and the best quality of service in this frequency band.
Unabhängig von der automatischen Frequenzbandauswahl auf Basis des Dienstes ist auch eine manuelle Auswahl des Frequenzbandes oder Netzes, gekennzeichnet durch die Netzkennung, durch den Nutzer nicht ausgeschlossen.Regardless of the automatic frequency band selection based on the service, manual selection of the frequency band or network, characterized by the network identifier, by the user is not excluded.
Durch so ein entwickeltes Mobilfunkendgerat ist eine optimale Nutzung der vorhandenen und zukünftigen zugeteilten Frequenzbänder eines Mobilfunkoperators möglich. Such a developed mobile radio terminal enables optimal use of the existing and future allocated frequency bands of a mobile radio operator.
