Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile telephone in which a transmission path from a base station to a subscriber station is wirelessly connected.
The present invention relates to a wireless telephone operation confirmation test method for performing a confirmation test of the operation of a subscriber station in a wireless subscriber system such as a mobile phone and a cordless telephone.

[0002]

2. Description of the Related Art In recent years, mobile phones, mobile phones, cordless phones, and the like have become widespread as subscriber phones due to advances in mobile communication technology. However, it is very difficult to test such a subscriber telephone because the subscriber telephone is connected by a wireless transmission path, and the only conventional test method is disclosed in Japanese Patent Application Laid-Open No. 56-13320. There is a "terminal station operation device confirmation method".

[0003] In this method, a terminal station (subscriber telephone) having a radio returns a pseudo response signal to a test signal from a master station (base station), so that an operation unit of the terminal radio and a radio line are connected. The test is performed. FIG. 4 is a block diagram showing a configuration of a system to which such a conventional method is applied, and FIGS. 5 and 6 are timing charts showing first and second timing examples of a line test in this conventional system. The line test operation of the conventional system will be described with reference to these drawings.

Now, in FIG. 5, it is assumed that the radios of the terminal stations 21 to 2n shown in FIG. In FIG. 6, it is assumed that the wireless unit of the terminal station 21 is active, the wireless unit of the terminal station 22 is active, and the wireless unit of the terminal station 2n is active. Here, master station 1
When each of the terminal stations 21 to 2n receives the test signal 4 from the terminal station 21, the terminal station 21 sends out the active equipment operation signal A as a pseudo response signal 5, and the terminal stations 2 to 2n are sequentially shifted in time.
2, the active unit operation signal A (in FIG. 6, the standby unit operation signal B) is transmitted as the pseudo response signal 5, and the terminal unit 2n transmits the active unit operation signal A as the pseudo response signal 5.
By monitoring the pseudo response signals transmitted from the terminal stations 21 to 2n, the master station 1 can perform a test of the operation equipment of the terminal station radio at the same time as the test of the radio line.

[0005]

As described above, in the conventional terminal station test, each terminal station is activated by a test signal from the master station. In this case, each terminal station performs a test by shifting the time from one another. A false response signal to the signal is returned.

However, when the number of terminal stations responding to the test signal increases, there is a problem that it becomes difficult to perform time allocation (timetable) for individually returning the pseudo response signal. Also, even if such a timetable can be managed temporarily, each terminal station does not always exist in the area of the same master station and moves to the area of another master station to change the master station. It is almost impossible for the station to manage the timetable described above. Further, if the timing of the pseudo response signal returned from each terminal station is shifted, there is a problem that the master station cannot accurately grasp the state of the terminal station. Another problem is that a special sequence for testing the terminal station must be prepared in both the master station and the terminal station.

[0007] Accordingly, an object of the present invention is to perform an accurate test with a simple configuration when testing a subscriber station (terminal station) that is a radio telephone.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As an operation test of a subscriber telephone connected by a physical transmission line, various tests such as a loop resistance test, an insulation resistance test, a capacity test, and an external voltage test have been generally known. However, when the subscriber telephone is wirelessly connected to the base station, the operation test is difficult, and a special sequence or the like for the test is required. In the present invention, when confirming the operation of the subscriber wireless telephone, the operation is performed without adding a special sequence.

That is, first, when a subscriber station (subscriber wireless telephone) is added under the control of the new base station, an operation confirmation start instruction is issued from the subscriber management station, which will be described later, to a base station having the subscriber station. Is sent. The base station performs the incoming call operation in accordance with the normal incoming call procedure, and when part or all of the incoming call procedure is completed, the return operation can be confirmed between the base station and the subscriber station. The base station sends the operation test result of the subscriber station to the subscriber management station as soon as the result of the operation check is found.

By the way, in the radio telephone system, if the following conditions are satisfied, the operation between the base station and the subscriber station can be confirmed. That is, the synchronization signal from the base station is supplemented (establishment of synchronization). Reception at accurate timing is established (reception establishment). Transmitting to the base station with accurate timing (transmission establishment).

FIG. 1 is a block diagram showing the configuration of a system to which the present invention is applied.
１1 m, n1１〜nm, base stations 1 and n, subscriber management station 10
Consists of FIG. 2 is a sequence diagram showing the operation of each of the subscriber station, the base station, and the subscriber management station constituting the system, and shows the operation when the present system is a PHS system described later. The operation of the main part of the present invention will be described with reference to this sequence diagram.

First, for example, the base station 1 is sent from the subscriber management station 10.
In contrast, each of the subscriber stations 11 to 11 in the area of the base station 1
An operation test start request of 1 m is sent in step S1.
The base station 1 that has received this sends an incoming call to the corresponding subscriber station in step S2. Upon receiving the incoming call, the corresponding subscriber station returns to the base station 1 a request (link channel establishment request) for assigning, for example, a frequency, a time slot, or the like of a radio channel of a radio channel, and the base station 1 responds to the request. The corresponding assignment is sent (step S3).

Thereafter, starting from the fact that the procedure up to the second layer has been executed / established on the channel allocated between the base station 1 and the subscriber station (step S4), the result is used as an operation test result as the base station 1 (Step S
5). The operation test result is sent to the subscriber management station 10 as a response to the operation test start request in step S1 (step S6). As a result, the operation test result from the base station 1 is stored in the subscriber management station 10 (step S7). If the above procedure is not completed due to any problem, the operation test result is determined to be defective and the base station 1
Is returned to the subscriber management station 10.

"SCCH" in FIG. 3 indicates a bidirectional channel (individual cell channel) for transferring information necessary for call connection between a base station and a subscriber station.
"CH" indicates a high-speed associated control channel for high-speed data transfer, and "PCH" indicates a one-way paging channel for performing paging to each subscriber station. Information is transmitted and received through these channels. Also,
In the figure, “SAMB” indicates a command for setting and starting a logical link, “DISC” indicates a link disconnection command, and “UA” indicates an acknowledgment command for each command of “SAMB” and “DISC”. ing. For such a PHS system, refer to “Radio Industry Association; 2nd generation cordless telephone system standard RCR”.
STD-28 ".

The operation shown in the sequence diagram of FIG. 2 enables an operation test to be performed immediately by using a part of a normal incoming call procedure. However, as shown in the sequence diagram of FIG. It is also possible to perform an operation test by making the incoming call procedure itself in the system function. That is, when an operation test start request for each of the subscriber stations 11 to 1m in the area of the base station 1 is sent from the subscriber management station 10 to the base station 1 in step S11, the base station 1 that has received the request has started.
In step S12, an incoming call is sent to the corresponding subscriber station. In this case, the procedure is performed between the subscriber station and the base station 1 in the same manner as in a normal incoming call (step S1).
3).

Then, the result after all the incoming call procedures are executed is temporarily stored in the base station 1 as an operation test result (step S14). Further, after the call termination procedure after the incoming call response (step S15), the operation test result is sent to the subscriber management station 10 as a response to the operation test start request in step S11 (step S16). As a result, the operation test result from the base station 1 is acquired and stored in the subscriber management station 10 (step S17). In this test procedure, it is necessary to silence the telephone ringer for the call to distinguish it from the normal incoming call procedure.
Also, it is necessary to automatically answer the call (step S18). Further, in the above example, the operation test start request is sent from the subscriber management station 10 to the base station to perform the test. However, even if there is no operation test request from the subscriber management station 10, the operation is started in the base station. It is also possible to arbitrarily (arbitrarily) perform an operation check test on each subscriber station and respond to the latest subscriber state information as an operation test result at the time of an operation check request from the subscriber management station 10. .

As described above, a subscriber station test is performed by executing a call receiving procedure in a portable telephone system such as a PHS system or a car telephone system. Therefore, without a special sequence for the test, the minimum required test by the loopback at the subscriber station is to establish synchronization, establish reception (receive call),
A test equivalent to a general operation check test can be realized by each operation check of transmission establishment (handshake of an incoming call procedure). It should be noted that such a test method can be applied to a WLL or the like that has recently attracted attention.

[0019]

As described above, according to the present invention, when a subscriber station is tested, it is possible to execute a call procedure performed between the base station and the subscriber station during a normal call. Since the test of the subscriber station is performed and the test result is transmitted to the subscriber management station, the test of the subscriber station can be performed without adding a special sequence for the test,
Therefore, an accurate test can be performed with a simple configuration. Further, since the subscriber station is tested by executing a part of the normal incoming call procedure, the test time can be reduced. In addition, the base station executes the call receiving procedure for the subscriber station at an arbitrary time interval, holds the execution result as a result of the operation test of the subscriber station for a certain period of time, and receives the result from the subscriber management station. Since the held operation test result is sent to the subscriber management station in response to the operation test start request of the individual subscriber station, the subscriber station can be tested at any time. Further, since the base station executes a part of the incoming call procedure at an arbitrary time interval for the subscriber station, the subscriber station can be similarly tested at an arbitrary time.
