Description

Die Erfindung bezieht sich auf ein Verfahren zur Animation einer Mobilfunkstation (MS) zum Anmelden bzw. Einbuchen in eine Mikrozelle.The invention relates to a method for animation a mobile station (MS) for logging in or logging into a micro cell.

GSM-Mikrozellen sind denkbar in mobilen Einrichtungen wie z. B. in Wasserfahrzeugen, Schienenfahrzeugen und in Luftfahrzeugen, aber auch als stationäre Mobilfunknetze für einen bestimmten Umgebungsbereich, z. B. in Gebäuden (Kasernen, Hotels und dgl.), auf Werksgeländen usf.GSM microcells are conceivable in mobile devices such as e.g. B. in watercraft, rail vehicles and in Aircraft, but also as stationary mobile radio networks for a certain surrounding area, e.g. B. in buildings (Barracks, hotels and the like), on company premises, etc.

Mikrozellen sind in sich geschlossene Mobilfunknetze, die über einen Gateway an externe Netze angeschlossen sein können oder ohne externe Verbindung nur in sich funktionsfähig sind. Im allgemeinen muß man davon ausgehen, daß externe öffentliche GSM-Mobilfunknetze vorhanden sind und diese nur durch extremen Abschirmaufwand (Farradayscher Käfig) vom gesamten Bereich der Mikrozelle zu trennen sind. Die Abschirmmaßnahmen sind im allgemeinen sehr aufwendig und deshalb meist nicht realisierbar.Microcells are self-contained cellular networks that connected to external networks via a gateway can or without external connection only in itself are functional. In general, you have to assume that external public GSM mobile radio networks are available and this only through extreme shielding effort (Farraday Cage) must be separated from the entire area of the microcell. The shielding measures are generally very complex and therefore mostly not feasible.

Mikrozellen müssen deshalb innerhalb eines externen GSM- Netzes in Zusammenarbeit mit einem oder mehreren externen Netzbetreibern funktionieren.Microcells must therefore be located within an external GSM Network in collaboration with one or more external Network operators work.

Kontroll- und Verkehrskanalzuordnungen müssen bei mobilen Mikrozellen deshalb (bei mobilen Mikrozellen dynamisch) mit den vorhandenen externen GSM-Netzen abgeglichen werden. Kontroll- und Verkehrskanäle der externen GSM-Netze müssen ermittelt werden und die Kontroll- und Verkehrskanäle der Mikrozelle dazu in interferenzfreie Bereiche gelegt werden.Control and traffic channel assignments for mobile Microcells therefore (dynamic with mobile microcells)  the existing external GSM networks are compared. Control and traffic channels of the external GSM networks must are determined and the control and traffic channels of the For this purpose, the microcell is placed in interference-free areas.

Damit eine MS sich jedoch innerhalb des Bereiches der Mikrozelle nur in die Mikrozelle einbuchen kann, werden erfindungsgemäß folgende Maßnahmen ergriffen:
However, the following measures are taken according to the invention so that an MS can only log into the microcell within the area of the microcell:

  • 1. Sämtliche externe BCCHs sind im Bereich der Mikrozelle oder im Zugangsbereich zur Mikrozelle zu unterdrücken.1. All external BCCHs are in the microcell area or suppress in the access area to the microcell.
  • 2. Der Location Area Ident Code, Network Color Code, Zellidentcode und Mikrocellcode müssen so angepaßt werden, daß die MS ein Location Update auf die Mikrozelle entsprechend GSM-C1- und -C2-Kriterien ausführt.2. The Location Area Ident Code, Network Color Code, Cell ID code and microcell code must be adapted so that the MS has a location update on the microcell according to GSM C1 and C2 criteria.
  • 3. Die Mikrozelle muß bei einem Location Update die entsprechenden für Roaming erforderlichen Maßnahmen durchführen. Eine externe Anbindung ist deshalb für MS mit SIM-Karten fremder Netzbetreiber unumgänglich.3. The micro cell must be the location update corresponding measures required for roaming carry out. An external connection is therefore included for MS SIM cards from other network operators are essential.

GSM-Mikronetze stellen autarke Netze in mobilen Einrichtungen oder in definierten stationären örtlichen Bereichen dar. Es soll dort erreicht werden, daß sich Mobiltelefone bei Eintritt in den Bereich des Mikronetzes dort einbuchen.GSM micro networks represent autonomous networks in mobile Facilities or in defined stationary local Areas. It should be achieved there that Mobile phones when entering the area of the micro network book there.

Ohne die erfindungsgemäße Lösung ist der Einbuchvorgang im allgemeinen nur manuell durch den Bediener des Mobiltelefons möglich. Nur durch extreme Abschirmmaßnahmen, die aber im allgemeinen aufgrund der räumlichen Anordnung der Mikrozelle zwischen Mikronetz und Makronetz nicht realisierbar sind, wäre ein automatisches Einbuchen möglich. Notwendige Abschirmmaßnahmen sind z. B. Schirmkabinen mit einer Dämpfung des Makronetzes in der Größenordnung von größer 60 dB im gesamten Freqzenzbereich des GSM-Makro-Netzes. Im gesamten Bereich eines Mikronetzes beispielsweise in Gebäuden, Schiffen, Flugzeugen sind derartige Dämpfungen eines Makronetzes nicht erzielbar.Without the solution according to the invention, the booking process is in generally only manually by the operator of the mobile phone possible. Only through extreme shielding measures, but which in generally due to the spatial arrangement of the microcell cannot be realized between the micro network and the macro network, an automatic login would be possible. Necessary Shielding measures are e.g. B. umbrella cabins with damping  of the macro network in the order of more than 60 dB in entire frequency range of the GSM macro network. All in one Area of a micro network, for example in buildings, Ships and airplanes are such damping systems Macro network not achievable.

Die Animation einer MS zum Anmelden bzw. automatische Einbuchung in die Mikrozelle ist ein wesentliches Merkmal, indem die BCCH's des externen GSM-Netzes durch geeignete Maßnahmen innerhalb der Mikrozelle unterdrückt werden (z. B. durch Hochfreqzenzüberlagerung von Störsignalen).The animation of a MS to log on or automatically Booking into the microcell is an essential feature by the BCCH's of the external GSM network through suitable Measures within the microcell are suppressed (e.g. due to high frequency interference of interference signals).

Die Mikrozelle paßt ihre Location Area, National Color Code, Zellidentcode und Mikrozellcode erfindungsgemäß entsprechend den Algorithmen eines Location Updates dem externen GSM-Netz an, so daß die MS ein Location Update auf die Mikrozelle entsprechend GSM C1- und C2-Kriterien ausführt.The microcell fits its location area, National Color Code, According to the invention, cell identification code and microcell code accordingly the algorithms of a location update to the external GSM network so that the MS does a location update on the microcell executes according to GSM C1 and C2 criteria.

Gemäß der Erfindung werden nur die BCCHs der externen GSM- Netze unterdrückt, so daß der laufende Verkehr (z. B. Gespräche bei Eintritt in die Mikrozelle) nicht beeinflußt werden.According to the invention, only the BCCHs of the external GSM Networks suppressed so that the current traffic (e.g. Talks when entering the microcell) are not affected become.

Es ist bereits ein Übergabeverfahren zur Animation einer Mobilfunkstation (z. B. 18 in Fig. 3 der GB 22 42 806 A) zum Anmelden bzw. Einbuchen in eine Mikrozelle bekannt. Dabei bucht sich die Mobilfunkstation in die Mikrozelle ein. Bei diesem Stand der Technik werden die Broadcast Control Channels des externen Netzes jedoch nicht unterdrückt, vielmehr erfolgt bei schneller Bewegung ein handover in die zugehörige Makrozelle oder bei langsamer Bewegung in eine benachbarte Mikrozelle.A handover method for animating a mobile radio station (for example 18 in FIG. 3 of GB 22 42 806 A) for logging on or logging into a microcell is already known. The mobile station logs into the micro cell. In this state of the art, however, the broadcast control channels of the external network are not suppressed; rather, there is a handover into the associated macrocell during rapid movement or into an adjacent microcell during slow movement.

Weitere bekannte Verfahren für die Übergabe eines Teilnehmers von einer Zelle zu einer anderen in einem Netz (EP 589 279 A2, EP 526 435 A1 und EP 562 743 A1) gehen davon aus, daß Makro- und Mikrozelle gleichzeitig existieren und legen die Bedingungen für die Übergabe durch externe Faktoren fest.Other known methods for the delivery of a Participant from one cell to another in a network (EP 589 279 A2, EP 526 435 A1 and EP 562 743 A1) assume that macro and micro cell exist simultaneously and lay down the conditions for delivery by external Factors.

Bei der vorliegenden Erfindung wird jedoch die Bedingung für die Übergabe des Teilnehmers durch die Mikrozelle gestellt. Auch ist eine Unterdrückung der Broadcast Control Channels der überlagerten Makrozelle durch Hochfrezqenzüberlagerung von Störsignalen dem Stand der Technik nicht entnehmbar. In the present invention, however, the condition for the handover of the participant by the microcell. It is also a suppression of broadcast control channels the superimposed macro cell by high frequency superimposition of interference signals cannot be removed from the prior art.
