Definitions

  • the invention relates to a method for measuring the quality of service in communication networks by means of determining and recording measurement data during a connection from or to a subscriber terminal and then transmitting this measurement data to a central test center.
  • the invention further relates to a system for performing this method.
  • a second possibility is that the network operator makes test calls himself in order to determine the desired measurement data.
  • special measuring stations are used, which are either permanently installed at critical points in the network or for mobile applications e.g. installed on a vehicle and can thus be brought to practically any location in the network.
  • measurements of this type are associated with enormous costs, because appropriate measuring stations are not only expensive to manufacture and maintain, but also to operate, i.e. setting up at certain locations and performing the measurements are labor-intensive and cause high costs.
  • the base station of a cell records the position of a mobile radio telephone and certain parameters of the radio connection, such as the signal quality or the signal strength, when a connection is established from this mobile radio telephone to the base station. It is also possible for the cell phone itself to collect this data and pass it on to the base station. However, even with this procedure, the measured data is not statistically or only to a small extent meaningful, because a measurement can only be carried out at precisely the time and only for the location in or at which a mobile radio subscriber is, if he is on his own initiative establishes a connection.
  • the object of the invention is to provide a method which allows measurements of the quality of service in communication networks to be carried out practically anytime and anywhere, regardless of the telephone habits of the mobile radio subscribers.
  • test center a central system
  • test center any mobile radio telephone.
  • the mobile phone must be in the "idle" state, i.e. it must be ready to receive or send, but there must be no active connection from or to the mobile phone.
  • at least one line must be free and therefore only this one line and not the entire device must be in the "idle” state.
  • the establishment of a test connection and the subsequent implementation of the measurements can be carried out automatically without intervention by the mobile radio subscriber. It is even possible to take measurements without the owner of the cell phone knowing it.
  • the time and the number of test connections to a particular mobile phone can be made dependent on various factors. If, for example, the test center has the same number of connection options as there are mobile phone subscribers in the area to be supplied, a test connection can of course be established at any time and as often as required, provided that the mobile phone is in the "idle" state. If, on the other hand, there are fewer connections as mobile radio subscribers, the next mobile radio telephone to or from which a test connection is established is determined taking various criteria into account. For example, the geographic position of the mobile phone, the time elapsed since the last test connection, the current time or the current load on the entire network or certain parts of it can have an impact.
  • the invention is in no way limited to compounds that are specifically constructed for test purposes.
  • the desired measurements can also be carried out during an existing connection from or to the mobile radio telephone, without the user being disturbed in any way. With a high network load, it even seems to make sense to use existing voice connections for measurement. Firstly, there is no need to set up additional test connections that place a greater load on the network, and secondly, measurement data from areas or times with high network utilization are of particular interest to the network operator.
  • the mobile radio telephone is equipped according to the invention with a corresponding device which immediately interrupts or terminates any test connection and an ongoing measurement if the connection request of another mobile radio subscriber arrives or if the user himself, for example by pressing a button, registers a connection request by opening the mobile phone or in another way.
  • a preferred embodiment of the invention consists in that the data to be measured are determined and recorded by the mobile radio telephone. The measurement data are then transmitted to a test center, which then evaluates this data. If the test connection is interrupted by an incoming or outgoing connection request before or while the measurement data is being transmitted to the test center, the measurement data remains stored until the mobile phone is in the "idle" state again and the next test connection can be set up so that all or the remaining measurement data can be transferred to the test center.
  • One of the options is to transfer the data immediately after a measurement via the existing test connection itself, or a separate test connection is set up for this later.
  • Another option is to send the data to the test center via a public message service after the measurement. E-mail via an Internet connection or SMS (short message service) with GSM (Global System Mobile) are examples of this.
  • the measurement data of all measurements can be collected by the mobile radio telephone over a certain period of time, stored and then transferred to any data carrier. This is then sent to the test center, where the measurement data can then be read out and processed.
  • all or part of the measurement data can also be determined and recorded by the test center itself.
  • a test connection according to the invention can be set up from the mobile radio telephone. It should be noted, however, that a connection from the mobile phone to the test center does not necessarily have to exist to measure the desired data. In principle, a connection from the mobile phone to any destination is sufficient. However, a connection to a public telephone service such as the "speaking clock", the "weather forecast” or the “road condition report” is advantageous, since in such connections voice data are transmitted which are used to measure the speech quality of the connection from this destination to the cellular phone (the so-called “downlink” connection quality). To measure the connection quality, however, the transmission of a voice signal is not absolutely necessary, and the transmission of a data signal via the corresponding connection also enables such a measurement.
  • connection quality is measured using a data signal instead of a speech signal, instead of a predefined speech sequence, a can also be used predefined data sequence to be transmitted to the receiver. If in the following therefore from a speech signal or a speech sequence, it should always be understood to mean a data signal or a data sequence.
  • connection quality In addition to the connection quality to the mobile radio telephone, the connection quality from the mobile radio telephone to the test center or to the base station is also of interest ("uplink" connection quality). To measure this, a voice sequence must also be sent in this direction so that it can be received and analyzed in the test center or base station. In this case too, this is advantageously a predefined voice sequence that is stored in the mobile radio telephone and is known at the point of reception.
  • test connection is established from the test center, the target is necessarily the mobile phone, since the data to be measured is to be determined at the location of the mobile phone at the time of the connection.
  • the test center does not set up a test connection itself, but prompts another station to in turn set up a test connection to the mobile radio telephone. The desired measurements can then be made there and the measurement data can then be transferred to the test center.
  • a mobile radio telephone according to the invention therefore has means to identify the number of the calling party (calling party number) and not to signal a call to the test center to the mobile radio subscriber, but rather to automatically establish a test connection and to determine or record the measurement data. If, on the other hand, the cell phone detects that the connection request does not originate from the test center or from a network element intended for carrying out tests, the connection request is treated like a normal telephone call and signaled to the mobile radio subscriber accordingly. The operator then has the option of rejecting the call or accepting the call and conducting the call.
  • a test connection before a test connection is established, whether this is done by the mobile radio telephone or by the test center, it is checked whether there is already an active connection from or to the mobile radio telephone. If this is the case, the connection establishment is aborted immediately or the connection request of the test center is rejected. Even when a test connection is established, the cell phone checks whether there is a connection request from the cell phone subscriber or an external caller. If so, the ongoing measurement of the desired data is interrupted immediately and the existing test connection is interrupted, and the mobile radio subscriber can continue to set up their connection or accept the incoming call without being aware of it.
  • test connection can also be signaled to the owner on or by the mobile radio telephone.
  • test center carries out some important tasks in connection with the invention. It decides to which mobile phone and with what frequency test connections should be established, establishes such test connections itself, sends or receives special speech sequences for analyzing the connection quality, carries out the measurement data acquisition, collects the measurement data recorded at the different locations and finally evaluates them. Instead of concentrating all of these tasks in one place on the network, it is of course also possible that several such test centers exist on the network. These can either all be of equal value, ie they can all perform the same tasks, or they can take on one or more of these tasks as required or set. For example, three test centers A, B and C could exist in a mobile radio network.
  • Test Center A decides when and to which mobile phones test connections are to be established and collects those from the test center.
  • the measurement data that are determined and recorded during a measurement can consist of all conceivable, measurable quantities in a mobile radio network.
  • the measurement data advantageously include information about whether a connection establishment was successful or not, about the field strength of the signals received on both sides, about the "up” or “down link” connection quality, about the frequency of errors of the data frames in which the Measurement data are transmitted (frame error rate) or any other type of error frequency or probability of the transmitted signals, the exact time at the time of the measurement, the exact geographical position of the mobile phone at the time of the measurement and the type, content , Number and destination or place of origin (as well as possibly other information) of the sent or received signaling messages
  • further parameters such as the bit error rate, which are required for the transmission of a data sequence, can be added Transmission time, the effective transmission rate (e.g. in bytes per second) or the number of the data blocks to be retransmitted due to transmission errors.
  • the analysis of signals received by the mobile phone can include other signals besides the signals from the test center or from the base station of your own cell. For example, signals from the base stations of neighboring radio cells can also be analyzed. Other measured variables can then be determined from this. Based on the delays in the signal transmission from or to the mobile radio telephone, its geographical position can be determined, for example. For this purpose, signals are sent from the mobile radio telephone to the various base stations, and from these back to the mobile radio telephone. The distances to the various base stations can then be calculated from the signal propagation times and the geographic position of the mobile phone can be inferred from these. In addition, stationary transmitters / receivers can also be included in such measurements. If the geographic position of the mobile phone needs to be known as precisely as possible, a GPS (global positioning system) can also be used, which is either integrated directly into the mobile phone or connected to it in any way.
  • GPS global positioning system
  • the signaling messages mentioned are used to transmit information from any element of a communication network (stationary telephone, mobile radio telephone, telephone exchange, test center, etc.) to any other element.
  • a communication network stationary telephone, mobile radio telephone, telephone exchange, test center, etc.
  • the measurement data as well as the "calling party number", which is required to identify the calling party could be transmitted to the desired destination by means of signaling messages.
  • Another preferred embodiment of the invention consists in that the functionality of the mobile radio telephone can be influenced from outside during ongoing operation. This is done, for example, with the aid of control signals which are sent with a signaling message before, during or after a test connection from the test center to the mobile radio telephone. In this way, e.g. certain start / stop conditions for the measurement or the desired type of data transmission can be defined. It is also very easy to implement a software update in the mobile phone.
  • a system for carrying out the measurement of the service quality according to the invention in a cellular communication network includes at least one test center and several mobile radio subscribers with a mobile radio telephone.
  • a communication network as is known, there are usually also other elements, such as normal telephone exchanges or so-called "operating systems", which e.g. handle the entire network management.
  • these elements only play a role in connection with the invention insofar as such elements or parts thereof can be identical to a test center according to the invention.
  • a mobile radio telephone of a communication system also includes means which serve to distinguish between a test connection between a test connection and a normal voice connection of a third party and to react accordingly.
  • a connection request from a test center is not signaled to the user, but is recognized as such by the mobile radio telephone, accepted and established as a test connection.
  • the desired measurements are then carried out, the measurement data recorded and forwarded to the test center.
  • a normal connection request from a third party is signaled to the mobile radio subscriber as usual, after which the subscriber can accept the call or leave it unanswered if necessary.
  • the mobile phone So that the owner of a mobile phone is not restricted by the automatically established test connections and the measurements carried out in the use of its device, the mobile phone also has means that enable it to recognize incoming or outgoing connection requests and to abort ongoing measurements immediately and terminate the test connections immediately so that the desired voice connection can be established by the owner.
  • Another advantage of the method according to the invention is that parameters can also be measured which depend on the entire route of a test connection, such as e.g. the "end-to-end” connection quality between a mobile phone and a test center, regardless of how many base stations or other network elements the connection is made through.
