Definitions
- UMTS Universal Mobile Telecommunication System
- UMTS Universal Mobile Telecommunication System
- the object of the invention is to show a way in which, in a radio communication system, the position determination of a specific subscriber device can be carried out on the network side in a simple and reliable manner.
- This object is achieved in a method of the type mentioned at the outset in that, on at least one request signal for determining the position of the respective subscriber device, one or more message signals between the radio network control unit which is assigned to the base station of the location radio cell of the respective subscriber device to be located, and at least one further one Position calculation unit can be exchanged in such a way that a position calculation for the respective subscriber device to be located is made possible on the radio network side.
- the invention further relates to a radio communication system which has means for carrying out the method according to the invention.
- FIG. 1 shows a schematic representation of the signaling of messages between a subscriber device to be located, a radio network control unit and an additional position calculation unit of a radio communication system for carrying out the method according to the invention
- Figure 2 is a schematic representation of the hierarchical
- FIG. 3 shows a schematic representation of the additional connection of the position calculation unit according to FIG. 1 to the respectively responsible radio network control unit.
- a service that is offered in a mobile radio system in particular according to the UMTS standard (universal mobile teleco communication system), is the so-called location service.
- One of the possible methods of determining a position is the so-called assisted GPS method.
- the mobile station to be located in each case is equipped with a GPS (global positioning system) receiver and measures signals which are emitted by satellites
- a method for determining a position is of no interest for this invention.
- UMTS standard a distinction is made between UE assisted and UE based methods.
- the position is calculated in the network of the radio communication system.
- the calculation of the position itself in the user device UE to be located is transmitted to the user device UE to be located for the assisted GPS method.
- the network receives this assistance data from a reference GPS receiver, which here in Figures 1 with 3 for the sake of clarity r has been omitted.
- the present exemplary embodiment deals only with the UE assisted GPS method, in which the position for the respective subscriber device to be located in the network is calculated.
- the subscriber device UE to be located is connected via an air interface S1 to a base station NodeB, which in turn is connected to the radio network control unit RNC (Radio Network Controller) via a landline connection S2.
- RNC Radio Network Controller
- FIG. 2 thus shows part of a radio communication system that otherwise has a multiplicity of base stations, such as NodeB, in associated radio cells FC, at least one radio network control unit (RNC) being assigned to a predefinable group of base stations (NodeB) for coordination.
- RNC Radio Network Controller
- one or more message signals are now sent between the radio network control unit that the base station, e.g. NodeB of the location radio cell FC of the respective subscriber device to be located, e.g. UE is assigned, and at least one further position calculation unit such as SMLC (see FIG. 3) exchanged in such a way that a position calculation for the respective user equipment UE to be located is made possible on the radio network side.
- the base station e.g. NodeB of the location radio cell FC of the respective subscriber device to be located, e.g. UE is assigned
- at least one further position calculation unit such as SMLC (see FIG. 3) exchanged in such a way that a position calculation for the respective user equipment UE to be located is made possible on the radio network side.
- the radio network control unit RNC sends one or more message signals (assistance data) via the air interface either to all subscriber devices of a radio cell (broadcast) or to a specific, individual subscriber device such as UE.
- the radio network control unit RNC sends a message (Measurement Control) to the subscriber device whose position is to be determined and requests it to take GPS measurements.
- the subscriber device such as UE then sends the measurement results (measurement report) back to the radio network control unit RNC, which then calculates the position therefrom.
- the radio network control unit inquires RNC with the aid of a message N1, assistance data request, assistance data from the position calculation unit SMLC, in order to then distribute it to all UEs (broadcasting).
- This message can expediently also contain information when the assistance data are to be sent to the radio network control unit RNC for the first time and / or a point in time when the GPS-SMLC should no longer send assistance data to the RNC.
- the message N1 can preferably contain a periodicity information, from which the position calculation unit SMLC can see that it can regularly send the assistance data.
- the position calculation unit SMLC receives in particular the additional functionality of regularly sending assistance data to the RNC.
- this assistance data is expediently supplied by the position calculation unit SMLC to the radio network control unit RNC by means of a message N2 “assistance data response *”.
- the radio network control unit RNC can expediently continue with a message N5 “Position Calculation Re- quest * inform the position calculation unit SMLC that it should determine the position of a desired subscriber device.
- this message preferably contains an identity of the subscriber device, the position of which is to be determined.
- the message contains information with which the radio network control unit RNC notifies the position calculation unit SMLC that the radio network control unit RNC requires assistance data. This is particularly advantageous if the RNC does not distribute the assistance data to all subscriber devices of the respective radio cell in which the subscriber device UE is located, the position of which is to be determined.
- the message can optionally also indicate a time when the RNC received assistance data for the last time.
- the position calculation unit SMLC can then decide whether the assistance data has changed since the last time and - if this is the case - only sends the assistance data that has changed since the last time. Furthermore, it may be expedient that the radio network control unit RNC responsible in each case forwards the last measurements received by the user equipment UE to be located and the time at which these were carried out to the position calculation unit SMLC. This is particularly advantageous because the GPS-SMLC can then decide whether the data is current enough and can already determine the position.
- the message may also contain information as to how exactly the position is to be determined.
- the message can expediently contain information about the start point, end point and periodicity. This is particularly advantageous because it is the position calculation unit SMLC can be made possible to determine the position in a certain period of time or also indefinitely.
- the message may also contain information about how the result (e.g. area or point with an inaccuracy) is to be passed on to the responsible radio network control unit RNC.
- the position calculation unit SMLC can request the radio network control unit RNC that on the one hand it can deliver the assistance data to the user equipment UE using the existing measurement procedures, and it can request GPS measurements to be carried out.
- the position calculation unit SMLC can also use this message to deliver the assistance data to the radio network control unit RNC.
- the message can in particular contain an identification of the user device UE to be located, the position of which is to be determined.
- the radio network control unit RNC After the radio network control unit RNC has received the GPS measurement results from the user equipment UE, the radio network control unit RNC delivers the results to the position calculation unit SMLC with the aid of a message N9 “Measurement Response”.
- the radio network control unit RNC If the radio network control unit RNC cannot deliver GPS measurement results, it sends a message N10 “Measurement Failure *” to the position calculation unit SMLC.
- This message preferably contains an identification of the subscriber device for which no GPS measurement results could be delivered. Furthermore, the message expediently contains information about the reason why the Measurement results could not be delivered. Possible reasons can be, for example, "too little assistance data *," no reception of results from the UE * and "UE not known at the RNC *. This is particularly advantageous because the position calculation unit SMLC thus knows the reason for the failure and can react to it. If, for example, the reason is "too little assistance data *, the position calculation unit SMLC can deliver more assistance data with the next" measurement request * message.
- the GPS measurement results could be delivered to the position calculation unit SMLC, and the latter could determine or calculate the position with the desired accuracy, it sends a message Nil “Position Calculation Response * to the radio network control unit RNC, in which the position and an indication of the Accuracy with which the position could be determined is included.
- the message preferably contains an identification of the user equipment UE to be located.
- the message may also include a time that indicates when the position was determined.
- the GPS position calculation unit SMLC expediently sends a message Nil “Position Calculation Failure *” to the RNC.
- This message preferably contains an identification of the user equipment UE, the position of which could not be determined.
- a reason for the failure of the position determination will expediently be included. The following reasons can preferably be given: "Insufficient measurement results *," Position could not be determined with the desired accuracy *. This is particularly advantageous since the radio network control unit RNC can then start the procedure again and eliminate any reasons for the error can.
