Abstract

The invention relates to the co-ordination of transmission interruptions in the radio traffic of a plurality of base stations (BS1 with BS10) in a cellular radio communication system (FN1) having a plurality of subscriber devices (MP1). To this end, at least one information signal (ARR12, RRR21) is transmitted between at least one first control unit (RNC1) associated with the base station (BS3) of the location radio cell (FZ3) of the corresponding subscriber device (MP1) to be localised, and at least one second control unit (RNC2) associated with the base station (BS8) of at least one adjacent radio cell (FZ8), over the temporal position of the transmission interruptions in the base station (BS3) of the location radio cell (FZ3) and/or the base station (BS8) of at least one adjacent radio cell (FZ8).

Claims

1. Method for coordinating the transmission interruptions of location measurement signals of a plurality of base stations (BS1 to BS10) in a cellular radio communication system (FN1), with the transmission interruptions of the plurality of base stations (BS1 to BS10) being carried out during their transmission of location measurement signals for determining the position of at least one mobile radio station (MP1) to be localized, with the radio traffic in the radio cells (FZ1 to FZ10) of the base stations (BS1 to BS10) being controlled using radio network controllers (RNC1, RNC2), with at least one information signal (ARR12, RRR21) relating to the temporal position of the transmission interruptions of location measurement signals of the base station (BS3) of the location radio cell (FZ3) and/or the base station (BS8) of at least one adjacent radio cell (FZ8) being transmitted between at least one first radio network controller (RNC1), which is associated with the base station (BS3) in the location radio cell (FZ3) of the mobile radio station (MP1) to be localized in each instance and at least one second radio network controller (RNC2), which is associated with the base station (BS8) of at least one adjacent radio cell (FZ8), with the temporal position of the transmission interruptions of the location measurement signal of the base station (BS3) in the location radio cell (FZ3) and/or of the base station (BS8) of at least one adjacent radio cell (FZ8) being coordinated on the basis of said information signal (ARR12, RRR21,

characterized in that

at least one inquiry signal (ARR12) is sent as the information signal from the first radio network controller (RNC1) of the base station (BS3) of the location radio cell (FZ3) to the respective second radio network controller (RNC2) of at least one of the adjacent base stations (BS8), with which the temporal position of the transmission interruptions of the location measurement signals of this respectively adjacent base station (BS8) is requested, or that at least one information signal (ARR12) giving notification of a previously selected temporal position of the transmission interruptions of the location measurement signals of the base station (BS3) of the location radio cell (FZ3) is sent from the first radio network controller (RNC1) of the base station (BS3) of the location radio cell (FZ3) to the respective second radio network controller (RNC2) of at least one of the adjacent base stations (BS8).

2. Method according to claim 1,

characterized in that

the transmission interruptions of the associated base stations (BS1 to BS7;

BS8 to BS10) are coordinated in such a way by the first radio network controller (RNC1) and/or the second radio network controller (RNC2) that one or a plurality of location measurement signals are sent essentially simultaneously from one or a plurality of adjacent base stations (BS1, BS2, BS8 to BS10, BS5) to the base station (BS3) of the location radio cell (FZ3), while this latter interrupts transmissions for a predefinable time period.

3. Method according to claim 1,

characterized in that

the transmission interruptions of the associated base station (BS1 to BS10) are coordinated in such a way by the first radio network controller (RNC1) and/or the second radio network controller (RNC2) that one or a plurality of location measurement signals are sent only individually from one or a plurality of adjacent base stations (BS1, BS2, BS8 to BS10, BS5) in a predefinable time sequence to the base station (BS3) of the location radio cell (FZ3), while the base station there (BS3) interrupts transmission for a predefinable time period in each instance.

4. Method according to one of the preceding claims,

characterized in that

location measurement signals are sent from at least three adjacent base stations (BS1, BS8, BS9) to the base station (BS3) of the location radio cell (FZ3).

5. Method according to one of the preceding claims,

characterized in that

transmission of the at least one information signal (ARR12) is carried out in a GSM (Global System for Mobile Communication), UTMS (Universal Mobile Communication System), GPRS (General Packet Radio Service) and/or in the EDGE (Enhanced Data Rates for GSM) radio communication system, in particular a mobile radio system.

6. Radio communication system (FN1) with a plurality of base stations (BS1 to BS10) in associated radio cells (FZ1 to FZ10), with at least one first radio network controller (RNC1) being associated with at least one first group of base stations (BS1 to BS7) and at least one second radio network controller (RNC2) being associated with at least one second group of base stations (BS8 to BS9) and with means (RNC1, RNC2) for implementing the method according to one of the preceding claims.
