METHOD AND SYSTEM FOR USING RADIO COMMUNICATION MEASUREMENT DATA

The present invention relates to telecommunications. In particular, the present invention relates to 5 novel methods and systems for utilizing downlink and uplink measurement data in the installation and in-service monitoring of a radio system.

In the Wireless 10 Local Loop (WLL), the terminal is connected to the access node or WLL controller via a radio connection. The subscriber network element may consist of multiplexers, cross-switching devices, and various transmission systems. The WLL system may be based, for example, on technology used in the mobile communication system, such as GSM / DCS1800 (GSM, Global System for Mobile Communications; DCS, Digital Cellular System). GSM is a pan-European digital mobile communications system standardized by ETSI. The DCS-1800 is an ETSI standardized mobile communication system based on the GSM specification 20o, aiming at more efficient use of microcells and operating in the 1800 MHz band. Also::: Other mobile technologies may be used.

The subscriber network element • · · or WLL controller can be connected to the PBX 30 using, for example, a V5.1 or V5.2 interface.

• · · * The functionality of the WLL terminal is strongly • · · V · dependent on the boundary between the terminal and the base station ···. the quality of the diode connection. Similarly, functionality may be affected by the state and quality of the connection between the base station and the access node. In current solutions, this * · • * ·· data is not collected in a single point, that is, *: * ”for the terminal device that is to be installed or used 2 106237 so that the information is available for installer or in-service monitoring.

For radio reasons, the best location and orientation of a WLL terminal or external antenna must be able to determine based on radio quality information using the strength of the signal transmitted from the base station to the terminal and the signal transmitted from the terminal to the base station. In addition, it must be possible to check the quality of the radio connection 10 even after installation during normal operation.

Nowadays, downlink radio quality information is available directly from the terminal because it itself measures that direction. Instead, the uplink-15 directional quality information is only available as measured by the base station, and is therefore not used at the installation site or during in-service monitoring as the downlink directional information.

Since the transmission link between the terminal, the base station and the subscriber-20 network element and its condition naturally affect the functionality of the terminal, optimizing the quality of the connection is of paramount importance.

Therefore, the present invention has as its object the • · *. ···. thus improving the availability of metering data for installation and monitoring while at the same time eliminating, or at least significantly reducing, the above problems.

In particular, it is an object of the present invention to provide a novel method and system by which an installer obtains radio communication information when installing or performing maintenance on a terminal. It is a further object of the invention to provide a system for improving customer service when performing on-the-spot monitoring, allowing the operator to participate in the interpretation of radio quality indicators.

As regards the features of the present invention, reference is made to the claims.

The method of the invention is directed to the use of radio connection measurement data in a telecommunications network. Preferably, the telecommunication network includes a local exchange, a subscriber network element connected to a local exchange, a wireless communication system comprising a base station and connected to a subscriber network element. In addition, the size of the communication network 10 includes a terminal which is connected to the access node by a wireless communication system. In the method, the terminal measures the quality of the radio link between the terminal and the base station in the downlink direction and the base station 15 measures the terminal in the uplink direction.

The connection between the local exchange and the local area network element can be implemented, for example, by means of a V5.1 or V5.2 interface. These interfaces are specified in the standard series ETS 300 324 and ETS 300 347, respectively.

According to the invention, the measurement data obtained at the base station and received by the terminal • · *. ··· is transmitted. the measurement data obtained from the transmitted signal, to the terminal and to the terminal, is transmitted to the terminal, which is referred to herein as the A-subscriber, • · * ··· 'during installation or during in-service monitoring. Usually, the quality of the connection is measured by two variables, Bit Error 30 Rate (BER) and power (dBm), which can be transmitted to the terminal as audio signals,; duration, volume, or other similar presentation indicates to the listener the quality of the connection. »The audio signals are transmitted over the voice path in the same way as • speech during the call and other audio information.

• «4 106237

In addition, the measurement data can be transmitted to the terminal, for example as GSM signaling. The information could then be transmitted using call control protocol messages according to GSM specification 04.08. An example could be the use of the User Information field as defined in GSM 04.08 9.31. The User Information field is specifically for free data and can be used to transmit manufacturer specific commands. In this case, the manufacturer may define the own commands required by the present invention 10, on the basis of which the terminal identifies the radio connection measurement data containing the User Information field. This terminal data is retrieved by the terminal and can be displayed in the same way as it represents the paths of signals transmitted by the base station. Thus, the terminal may use a built-in mechanism to display the measurement data of the signals measured by the terminal to display the measurement data of the signals it transmits which it receives from the base station.

An advantage of the present invention over the prior art is that the system makes it easier to find the right location for the terminal when installing the terminal to the subscriber. In addition, the inventive inventions. This allows the installer to check the correct location of the installation.]], 25 based on the strength of the signals transmitted in both directions. Likewise, the invention allows the connection problems occurring during use to be more easily investigated by both the subscriber and the operator. In addition, the subscriber and the operator can simultaneously communicate and thus talk to the main user.

Ml::! the location of the device.

Furthermore, the invention is a clear improvement over the conventional GSM system (on which WLL solutions are generally based), since the uplink measurement data is not defined in the GSM system to be transmitted to the terminal.

• · 106237

Advantageously, the measurement data may be transmitted, for example, as a tone to either subscriber A or subscriber A and B during installation or during an in-service monitoring operation. The measurement data transfer function for subscriber A can be activated by calling the first predefined subscriber number, the so-called. test number. The connection quality check is then initiated, extending from the subscriber terminal to the local exchange. Similarly, the data transfer function for subscriber A and subscriber B is activated by calling another predetermined subscriber number. At the same time, the quality of the entire connection can be checked.

When the subscriber network element detects that the subscriber selection leads to a test number and possibly 15 has already made a call to the local exchange, the call is released and the connection measurement data conversion to tone signals is activated and transmitted to the A subscriber. This occurs when the subscriber calls the first predetermined test number. If the T-20 Broad dials to another predetermined test number, a call will normally be made to the B-subscriber. When the subscriber network element detects that this is another predetermined test number, the subscriber network element • «. ··· activates the conversion of the measurement data to a tone • · Ϊ '·' 25 and its transmission to the A and B subscribers. The subscriber B can be, for example, an operator's service number, whereby a representative of the operator or an automated machine can listen to the customer's four tones indicating the quality of the connection • · · ·. · * With the same voice connection and thus discuss 30 steps that the customer can take to improve the quality of the connection.

In addition, the choice of subscriber from the terminal to the subscriber network element and thereby further to the local · · · '· * / business center can be arranged in two ** y * 35 ways. In non-transparent connection set-up, the call is initiated from the terminal so that the selection.: ··· is completely transmitted in the message frame transmitted between the base station and the terminal. In this case, the subscriber network element receives the selection from the message frame and, in the case of a number reserved for checking the quality of the connection and transmitting the measurement data to the A-subscriber, this measurement conversion and its transmission to the A-subscriber is activated. The call is not connected from the access node to the local exchange. Similarly, in the case of another predetermined test number, a connection is made to the B-subscriber 10 and the measurement data is converted into a tone which is transmitted to the A-and B-subscribers.

In a transparent connection set-up, the call is initiated from the terminal so that the selection is transmitted with the terminal and the subscriber network element in speech mode up to the local exchange. Then, the state-to-network network element interprets the selection from the terminal one by one. When the subscriber network element detects that it is a test number reserved for checking the quality of the connection and transmitting the mit-20 background information to the subscriber, the subscriber network element activates that conversion of the metering data to the tone and transmits to the subscriber. The call is not made from the subscriber network element in the local exchange. control center. If, on the other hand, the subscriber network element detects • · Y '.' Seeing that the tones also have to be transmitted to the B-subscriber, the connection to the B-subscriber is established, and the tones are also subscribed to the B-subscriber.

The present invention also relates to a system for using radio communication measurement data in a 30 communications network. With respect to the telecommunication network, we refer to the preferred telecommunication network described in the above method.

The system according to the invention includes means for measuring the quality of the radio connection between the base station and the base station * ··· '35 in the direction from the base station to the terminal · * · .. and means for measuring the radio connection quality from the terminal to the base station.

Preferably, the means for indicating the measurement data is implemented by a buzzer or a light-emitting diode. Other embodiments may also be used.

With respect to the advantages of the system of the present invention, we refer to the advantages of the method described above.

In a preferred embodiment of the system according to the invention, the system includes means 15 for transmitting tone signals also to the called party B subscriber. In this case, the B subscriber, which may be an operator, for example, receives important information about the quality of the uplink connection.

Preferably, the system also includes means for activating a measurement data transmitting function for the A-subscriber when the A-subscriber calls the first predetermined subscriber number. Similarly, the system includes means for activating the measurement data relay function for subscriber A and subscriber B when t · · ”25 subscribers call another predefined subscriber • · · * · * · *.

In a preferred embodiment, the system includes means for monitoring measurement information in a B-subscriber interface and for instructing 30 terminal users through a telecommunications network to locate the terminal. other radio related matters.

Preferably, the system of the invention also includes means for terminating normal call setup when the A-subscriber selection is directed to the first or second predetermined subscriber number. Preferably, the system also has means for adding the dial information in its entirety to the message frame and means for transmitting the dial information to the local exchange when the terminal and the subscriber network element are in voice communication. The method of transmission of the choice information-10 is selected on a case-by-case basis.

The present invention will now be described, by way of preferred examples, with reference to the accompanying drawing, in which: Figure 1 shows a preferred communication system according to invention 15; and Fig. 2 is a flow chart illustrating a preferred embodiment of the present invention.

The system shown in Fig. 1 includes a local exchange LE and a local area network element AN connected to it by a V5 interface. A terminal MS is connected to the access network element by wireless communication system 20. In addition, another terminal, subscriber B, is connected exemplarily to the local exchange, • ». ···. which is denoted by arrow B. The wireless communication system · * · 25 thus consists of a base station BS and a terminal MS connected to it by a radio connection. The connection between the terminal **** and the local exchange is established «* · * · * · * in a transparent manner so that the operation of the terminal corresponds essentially to the operation of a conventional telephone connected to a wired telephone network 30.

: T: The terminal is provided with means 4 for providing a subscriber tone to a subscriber network element or a base station for transmitting a radio connection * »i

based on information. When the access node AN

• * * ·; ** 35 knows the measurement results, it can use its own tone generator to generate suitable tone signals and transmit it to the terminal. For example, 9106237 quality scale 1-5 could be represented by 1-5 beeps, whereby the subscriber has a specific tone sequence corresponding to the connection quality from the subscriber.

In addition, the terminal is provided with means for inserting 10 selection information in its entirety into the message frame. As such, the means 10 are conventional mobile telephone technology and are familiar, for example, from the GSM system.

The base station includes means 2 for measuring the signals from the terminal 10, from which the quality of the radio connection from the terminal MS to the base station BS can be deduced. The means 2 can be implemented using the standard feature of a base station as defined in GSM standard 05.08.

Means are provided on the access network element 3 for transmitting the measurement information of the base station to the terminal. The means 3 for transmitting the measurement data may also be implemented to the base station. The subscriber network element further comprises means 5 for transmitting tone 20 to the called party, subscriber B.

The implementation of the means 3 and 5 may be similar to that of the means 4. If the means for transmitting the measurement data 3 is arranged to the base station, the means 5 are connected to transmit the tones to the called party to obtain the measurement information. In addition, the subscriber network element includes means 6, 7 for controlling the subscriber's choice and the basic selection if it is detected that the subscriber is calling. first · * · V or second predetermined test number, the metering data transfer function for subscriber A: T: or subscriber A and B is activated.

In this situation, the call set-up • .... · is not completed, ie over the V5 interface to the local exchange 10 106237. The selection stops at the access node AN between the subscriber / base station and the local exchange. If the subscriber selection information is transmitted over a voice connection between the terminal MS and the access node AN 5, it is implemented by means 11 provided in the access node element. This is implemented as a normal call setup.

The B-subscriber terminal B connected to the local exchange LE includes means 8 for observing metering-10 information and giving instructions to the A-subscriber. Thus, monitoring and giving instructions may be performed automatically or the task of the means 8 may be performed by a natural person in speech communication with the user of the terminal MS.

Referring now to Figure 2, a simple and advantageous embodiment of the method of the present invention will be described. Initially, the subscriber makes a selection and dials a predetermined first or second subscriber number, block 21.

Thereafter, the connection is continued ♦ · «for subscriber B, block 28. When connection • · 35 is established, proceed to block 29 and activate the metering data transfer function for subscriber A and B.
