Definitions
- the invention relates to a method for operating a terminal in a radio communication system, a radio communication system, a terminal and a confirmation unit for a radio communication system.
- radio communication systems data is transmitted from radio stations via an air interface.
- Known radio communication systems are, for example, wireless local area networks (WLAN, wireless local area network) and mobile radio systems for which numerous standards are known.
- WLAN wireless local area network
- GSM Global System for Mobile communications
- UMTS UMTS
- reconfigurable terminals are known in particular in mobile radio systems. These are reconfigured using software downloads carried out via their air interface. This enables an update of their operating system, which, for example, even enables them to be used in mobile radio systems that the terminal was not able to do before the reconfiguration.
- the invention has for its object to reduce the likelihood of a radio communication system being influenced by malfunctioning terminals.
- the method according to the invention for operating a terminal in a radio communication system provides that the terminal is only permitted to operate in the radio communication system if there is a confirmation that the terminal will be checked for correct functioning during its operation. This enables the terminal to be deactivated even before the actual checking of the functioning of the terminal is carried out. If a subsequent check of the functionality cannot be guaranteed, it cannot be decided whether the end device is working correctly or not. Since undetected defects of the end device can have extremely adverse effects on the radio communication system, its operation is already prevented if it is certain that the intended check cannot be carried out properly.
- the method according to the invention is advantageously carried out in the communication system immediately or shortly after the terminal is put into operation.
- the method according to the invention has the advantage that negative
- Influences of a defective terminal on the communication in a radio communication system cannot be prevented until a corresponding check of the functioning of the terminal has been carried out. Rather, this can happen as soon as it is certain that the intended verification of the functioning cannot be guaranteed. This can be the case, for example, if a malfunction of the communication system or of the units provided for the check makes a proper check impossible. However, this can also be the case, for example, if there are currently insufficient resources available to carry out the check.
- a confirmation signal is provided which, when transmitted to the terminal, indicates that the terminal will be checked during its operation.
- the terminal is approved for operation in the communication system by transmitting the confirmation signal to the terminal. In this way it can advantageously be achieved that the operation of the terminal is automatically prevented if the confirmation signal is not present.
- the terminal device transmits a request signal to a confirmation unit before it is approved for operation in the communication system, whereupon the confirmation unit initiates the test of the terminal and transmits the confirmation signal to the terminal.
- the radio communication system learns of the existence of the terminal via the request signal and can provide the resources necessary for checking the functioning of the terminal, which is signaled by the confirmation signal sent by the confirmation unit.
- the request signal to the confirmation unit contains an address previously stored in the terminal, which is predetermined for use by a plurality of terminals, at least in this communication system. This enables the request signal from the terminal device to actually
- the address of the confirmation unit used for this can either have already been stored in the terminal during the manufacture of the terminal or during a subsequent configuration of the terminal by software download. However, it is also possible
- ⁇ 25 nication system is applicable. If the terminal is then able to establish communication in these multiple communication systems, it can already start up by sending out the same address without additional knowledge of the details of the respective communication system.
- the terminal only sends out the request signal after a predetermined period of time has elapsed after it has logged on to the communication network in which it has not already received the confirmation signal automatically Has.
- Registration means a process in which the terminal provides the communication system with knowledge of its existence. The communication system is then able to automatically confirm the subsequent check of the functioning of the terminal without having to transmit the request signal beforehand.
- Such a procedure is possible in particular in radio communication systems that are operated by a system operator (operator) who is responsible for the necessary check. System operators of this type exist in conventional mobile radio systems such as GSM and in the planned UMTS.
- the device for carrying out the check is advantageously determined in such a way that the device is as close as possible to the terminal. It is thereby achieved that signals to be transmitted between the terminal and the device for carrying out the check have to be covered only relatively short distances during the check, so that overall the capacities of the communication system are loaded as little as possible by these additional signals.
- the terminal itself can be determined as a device for carrying out the check, software which is required for carrying out the check being fed to the terminal via an air interface.
- the signals generated by the terminal are checked by the terminal itself before they are transmitted via the air interface.
- the program for carrying out the check can be updated continuously by means of a software download via the air interface and can be adapted to the respective communication system in which the terminal is currently located. The program mentioned can even be selected depending on a current location of the terminal in the communication system.
- the further operation of the end device in the communication system is only subsequently refused if the end device is checked for correct functioning during operation, a certain number of errors or an error that has a certain threshold value - exceeded, resulted.
- This procedure allows the continued operation of the terminal in the event of errors which are recognized, but which are still tolerable for the operation of the entire communication system. Only when the number of errors or the severity of the error is no longer tolerable for the operation of the communication system is the terminal excluded from further operation.
- the radio communication system according to the invention, the terminal for a radio communication system and the confirmation unit for a radio communication system according to the independent claims have the components necessary for the method explained and are designed in a corresponding manner for carrying out the method.
- FIG. 1 shows a section of a radio communication system according to the invention
- FIG. 2 shows the sequence of the method according to the invention for the radio communication system from FIG. 1 in a schematic illustration
- FIG. 3 shows a flowchart for carrying out a check of a terminal within the communication system from FIG. 1
- FIG. 4 shows the terminal from the radio communication system from FIG. 1.
- FIG 1 shows a section of a radio communication system WLAN; GSM.
- a terminal MS in the form of a mobile subscriber station which can be configured via an air interface by transmitting appropriate software so that it can be operated in communication systems of different standards.
- the communication system can either be a centrally organized system for which a system operator (operator) is present, as is the case, for example, with the GSM system.
- the WLAN communication system can also be a decentrally organized one for which there is no system or network operator, as is the case, for example, with ad-hoc networks.
- the terminal MS considered here can be operated in both types of radio systems.
- the WLAN communication system; GSM has a network access station AP; BS, which is usually referred to as access point AP in the case of the ad hoc network WLAN and as the base station BS in the case of a GSM network.
- the network access station AP; BS is connected to a confirmation unit CU, the function of which will be explained in more detail below.
- the confirmation unit CU has several locally separated components SC, SP, SP V. One of these components is an SC inspection center.
- the confirmation unit CU has two checking devices SP, SP '. The above- test center is used to select one of the checking devices for performing a check of the end device for correct functioning.
- the checking devices SP, SP X are used to carry out a corresponding check of the terminal MS, provided that they have been previously determined by the checking center SC.
- the units SC, SP, SP 1 within the confirmation unit CU can be made available by one or more different service providers. If the radio communication system from FIG. 1 is a GSM network, the components SC, SP, SP 'of the confirmation unit CU are preferably components of the radio communication system. If the communication system is an ad-hoc network or another system without a system operator, at least the monitoring center SC, but preferably also the monitoring devices SP, SP X, are special
- the checking center SC in FIG. 1 can also determine that the terminal MS itself checks its functioning.
- the monitoring center SC transmits via the network access station AP; BS corresponding software SW over the air interface to the terminal MS.
- the software SW then enables the end device MS to be checked automatically.
- FIG. 1 shows from left to right process steps through the different components of the radio communication network WLAN; GSM from Figure 1 can be performed. From left to right in FIG. 2, these components are the terminal MS, the network access station AP; BS, one of the inspection facilities SP and the inspection center SC.
- the first step is a reconfiguration of the terminal MS initiated.
- the terminal MS first waits a period of time t whether it is from the radio communication system WLAN; GSM receives a confirmation signal that indicates that the terminal will be checked for correct functioning during its operation 5.
- a confirmation signal which is denoted by S2 in FIG. 1, is only generated automatically by the communication system if it is one with a system operator, in the present case it is the GSM network GSM.
- S2 confirmation signal
- step four proceed immediately to step four.
- the terminal MS is currently in the ad hoc network WLAN. Since this lacks a central system operator, the end user receives
- the checking signal SC determines that the checking device SP should carry out the check of the terminal MS for correct functioning.
- the monitoring center SC selects the monitoring device SP that is closest to
- the monitoring device SP selected by the monitoring center SC transmits a confirmation signal to the network access station AP; BS, which transmits the confirmation signal S2 (compare FIG. 1) to the terminal MS in a sixth step.
- the terminal MS After receiving the confirmation signal S2, the terminal MS continues its operation. If the terminal MS did not receive a confirmation signal S2, this would mean that the terminal has not been granted approval for operation and the terminal MS would deactivate itself.
- a seventh step the air interface A between the terminal MS and the network access station AP; BS checked by the monitoring device SP for correct signals from the terminal MS. If a malfunction of the terminal MS is subsequently detected by the monitoring device SP in an eighth step, this is done in a ninth step by the network access station AP; BS communicated, whereupon in a tenth step to remedy the error, the terminal is reconfigured by a software download. The ten steps described can then be carried out again.
- FIG. 4 shows the terminal MS from FIG. 1.
- the terminal MS has a processor MSP for controlling its functions. Furthermore, it has a timer T for measuring the time period t according to the second step from FIG. 2.
- the terminal MS also contains a memory in which the address ADR of the confirmation unit CU or its monitoring center SC is stored. Furthermore, there is a deactivation unit DA which effects the described deactivation of the terminal MS, provided that either no confirmation signal S2 is received via the receiving device MSRX or a special deactivation signal is received, which is the case in the event of an error in the functioning which is detected by checking the operation of the terminal MS is the case.
- the monitoring devices SP, SP 'and the monitoring center SC in FIG. 1 have receiving devices and transmitting devices for receiving or transmitting the corresponding ones Signals and a processor each, which serves to control them.
- the method for generating the confirmation signal S2 is first initiated (block 100).
- a check is made in block 100a as to whether the confirmation signal S2 has been transmitted to the mobile station MS. If this is not the case, the terminal MS deactivates itself automatically (block 100b). If this is the case, on the other hand, the functionality of the terminal MS is checked during its operation (block 101). In the event of an error, it is first checked whether the error can be remedied (block 102).
- the reason why the terminal MS is not immediately deactivated even in the event of an unrecoverable error is that due to a possible movement of the terminal MS in the radio communication system at a later point in time (for example when leaving the current cell of a cellular mobile radio system and entering the area) a new cell) the requirements for the correct operation of the terminal MS can change.
- the error is remedied by appropriate instructions from the monitoring device SP to the terminal MS (block 103). This is done by putting the terminal MS in a corresponding operating state. If, on the other hand, the detected error cannot be remedied, the existing connection of the terminal MS, via which the signals S in FIG. 1 are transmitted, is interrupted (block 104). The current checking results of the monitoring device SP are then compared with older measurement results which the monitoring device SP has previously determined for the same terminal MS (block 105). An examination is then carried out to determine whether the same error has already occurred several times and whether a predetermined number of the same error has already been exceeded in this case. Alternatively, instead of comparing with previously If an error occurs, the severity of the error is also checked (block 106).
- the number of permissible errors or the severity of the just tolerable error depends on where the terminal MS is within the WLAN communication system; GSM is currently located.
- the current position can be determined, for example, via a corresponding location service provider or by using information from mobility management. If the terminal MS is, for example, in a private environment (home of the subscriber) or in an environment with usually low traffic volume, the requirements for the error-free operation of the terminal MS can be lower than in areas with high demands on the Reliability of operation or with high traffic.
- the terminal MS remains authorized for further operation and is switched to a stand-by mode (block 107). If, on the other hand, the specified number of errors is exceeded or the severity of the error is no longer tolerable, the terminal MS is deactivated by a corresponding signal from the monitoring device SP (block 108).
- the monitoring device SP can monitor the signals S emitted by the terminal MS for compliance with protocols which are used by the WLAN; GSM applicable standard are set.
- the monitoring center SP from FIG. 1 also has the option, instead of the monitoring device SP, SP X, of determining the terminal MS itself for carrying out the check for correct functioning.
- the monitoring center SC can be accessed via the network access station AP; Download the appropriate test software SW to the terminal MS. The Terminal MS then uses this test software SW to carry out its own check.
- the address ADR of the monitoring center SC used for sending the request signal S1 is advantageously valid for all possible communication systems in which the terminal MS can be operated (for example after it has been made suitable for such systems by appropriate software downloads).
- the address ADR can, for example, be a specific telephone number that applies to all communication networks. Such an address ADR would then be comparable to the emergency numbers which are common today and which are uniform in a wide variety of mobile radio systems. For Germany, this emergency number is, for example, "112".
- the invention is suitable for use in any terminal equipment MS that can be reconfigured by software downloads. It is suitable for use in any radio communication network in which such reconfigurable end devices can be used.
- monitoring center SC it is also possible that instead of just one monitoring device SP, several monitoring devices SP, SP ⁇ and, under certain circumstances, also the terminal MS itself simultaneously monitor the functioning of the terminal MS during its operation. This is also determined by the monitoring center SC. Each of the units involved in such a check can monitor or check certain parameters or protocol messages of the terminal MS assigned to it by the monitoring center SC.
- the selection of the checking device SP that carries out the checking by the checking center SC can be carried out not only from the point of view of minimizing the data traffic in the entire communication network but also from the point of view that the computing-intensive checking measures are evenly distributed between the available inspection devices SP, SP ⁇ .
