Abstract

PROBLEM TO BE SOLVED: To test line connecting operation in a real field by enabling the line connection of plural mobile equipments by providing a controller having a prescribed function. SOLUTION: A simulator 5 is provided with the controller, transmission part, reception part and interface. When executing the test of 'tripartite speaking start/switch', for example, on the assumption that a call is originated from mobile equipment A of a user A, by off-hooking not the simulator 5 but mobile equipment B, communication with a user B is performed. The user A originates a call from the mobile equipment A again and communication with a user C is performed. By performing the simulation like this manner and tracing all the sequences between mobile equipment A to C and the simulator 5, even when the desired equipment to be tested at once is any one of mobile equipment A to C, the sequence can be confirmed. Therefore, the test is enabled on the condition of actually performing tripartite speaking.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio base station simulator used at a production site for manufacturing a large number of mobile units for mobile communication and for performing a line connection operation test of the mobile units.

[0002]

2. Description of the Related Art In a production factory that manufactures a large number of mobile phones and mobile phones for mobile communications, various kinds of materials are processed and assembled until the products are completed. Inspections and tests such as inspection and completion inspection are strictly implemented.

At the stage of completion inspection in various tests and inspections,
A radio base station simulator is used as one of test devices for performing a line connection operation test controlled by a base station.

[0004] The radio base station simulator connects the mobile units to be tested one by one sequentially, and the standard for mobile units of the Radio System Development Center (RCR): RCR-STD
This is a pseudo test device for performing a line connection operation test of the communication control system layer 1, layer 2, and layer 3 specified in 27X. The radio base station simulator can freely set the sequence determined in the standard RCR-3TD27X for each mobile device, freely set the structure of the control channel,
The system is configured to monitor by performing various operations based on a combination of parameters such as free setting, to determine whether the test result is acceptable or not, and to display the result.

FIG. 4 is an explanatory view of a test of a conventional simulator.
C) 2 and test the mobile station (MS) 3 with TDMA radio waves. For example, "SA in link setting waiting state
When a test called "BME reception" is to be performed, the test is realized by the following procedure. The sequence and operation at this time are as shown in FIG. 1) Make a call from the mobile device 3. 2) Go off-hook on the simulator 1 side to make a call. At this time, the mobile device 3 enters a multi-frame setting state. 3) The simulator 1 sets a test setting of "transmit a DISC", and the simulator 1 transmits the DISC. After receiving the DISC, the mobile station 3 enters the multi-frame non-setting state (RCR-STR27C 4. 2. 2. 5. 5.
42). 4) Next, the simulator 1 makes a test setting of "transmit SABME while waiting for link setting". 5) The mobile device 3 presses its own keypad, and the SABME
Send I. As described above, conventionally, when conducting a comparative study of a new model, an old model, a competitor's product, etc. in the development of a new model, the test time is extremely long since this operation must be performed for the number of models. There is a problem that it is long.

However, the above SABME is an unnumbered command, and is used to make the mobile station side or the network side perform modulo 64 confirmation type multi-frame operation. SABME
When sending a command, all abnormal conditions are cleared. DISC is an unnumbered command,
Used to end multi-frame operation.

Next, with a conventional simulator, for example,
When performing a test called "three-way call activation / switching", FIG.
When confirming the sequence (excerpted from RCR-STD27C): 1) It is assumed that a call is made from the mobile device of user A. 2) Communication with the user B is performed by off-hook of the simulator. 3) It is possible to simulate by calling again from the mobile device of user A and communicating with user C. In this case, the only sequence that can be confirmed is the sequence between user A and the network, The network and the sequence of the user C and the network must be separately determined and executed.

Conventionally, a communication test of a mobile station emits the same radio wave as that emitted from a base station and uses a PDC (Personal Digital Cellular) checker for testing whether the mobile station can talk. This is performed under the condition that the mobile device operates normally. However, on a real field, the actual device is not always in a normal operation state, and may be in a quasi-normal operation. for that reason,
There is a possibility that a mobile device that has shown a high call rate in the test, but has a low call rate in the actual field, may cause a malfunction.

[0009]

As described above, when a mobile station is actually used in the field, it is usually
There are a plurality of mobile stations in one zone of the wireless base station, and there are various ways of using the mobile base station with other mobile stations in the same zone through the wireless base station, or with mobile stations in other zones, or a three-party call. is there. Therefore, there is a problem that a conventional simulator using one-to-one connection as a product test is not enough to simulate the line connection operation of a plurality of mobile devices in use in the field.

It is an object of the present invention to provide a radio base station simulator which can connect a plurality of mobile units to a line and can test a line connection operation in an actual field.

[0011]

SUMMARY OF THE INVENTION A mobile radio base station simulator according to the present invention includes a transmitting means for transmitting a test radio wave of a control channel and a voice channel of a time division multiple access system to a mobile station, with the mobile station as a test object.

The transmitting means and the receiver set by a personal computer in accordance with the set sequence program. And a controller configured to simultaneously perform a line connection operation test to determine pass / fail and to perform a connection test between any of the plurality of types of mobile devices. Things.

[0012]

FIG. 1 is an explanatory view of a test by a simulator 5 of the present invention, in which a plurality of mobile units (MS) A,
B and C can be tested for connection at the same time. That is, the sequence can be compared by performing a single operation by combining and testing several types of products such as a company's own product, an old product, and another company's product, so that the labor of the test can be reduced.

FIG. 2 is a block diagram showing an embodiment of the present invention. The controller 6 includes a controller 6, a modulator 7, a transmitter 8, a receiver 9, a demodulator 10, and an interface 11.

For example, if "SABM is waiting for link setting"
In the case of the simulator of the present invention, the following operation is performed only once, and the sequence can be confirmed by tracing all the sequences of the connected models. The examination work can be simplified. 1) Make a call from the mobile station MS. 2) Go off-hook on the simulator 5 side to make a call. At this time, the mobile station MS enters a multi-frame setting state. 3) On the simulator 5 side, make a test setting of “transmit DISC” and transmit DISC. The mobile station MS is D
After receiving the ISC, the multi-frame is not set (RC
R-STR27C 4. 2. 2. 5. 5. 42). 4) On the simulator 5 side, "SAB while waiting for link setting
Send ME ". 5) The mobile station MS presses its own keypad, and the SABM
Send EI.

As described above, when the simulator of the present invention is used, when a new model is to be developed and compared with a developed product, an old model, a competitor's product, etc., such a test must be performed in a single operation. Can be.

Next, a description will be given of how to make a situation used in a real field easier. For this reason, for example, when performing a test of “three-way call activation / switching”, when confirming the sequence of FIG. 3 (excerpted from RCR-STD27C), it is assumed that 1) a call is made from user A's mobile device A. . 2) Communication with the user B is performed by off-hook the mobile device B instead of the simulator. 3) User A makes a call again from mobile device A and communicates with user C. If the simulation is performed as follows, mobile units A, B, C
By tracing the entire sequence between the simulator and the simulator 5, it is possible to confirm the sequence regardless of the case of the mobile device A, B, or C, which is to be tested at one time. It is possible to perform a test in a situation in which a three-party call is actually being made.

Here, off-hook of the simulator usually means that a call is made by picking up the transceiver on the called side, as in the case of making a call. When the mobile device and the simulator are connected, the simulator does not have a communication state unless the simulator has the off-hook function. Therefore, the simulator is conventionally provided with this function.

Further, according to the present invention, it is possible to make a call between mobile units and to perform a simulation at that time. Conventionally, a call test of a mobile device is performed under the condition that the mobile device is operating normally using a PDC checker. In the test, a mobile device showing a high call rate has a low call rate in a real field. The phenomenon of low was also occurring. However, if the simulator of the present invention is used, it is possible to make a call or receive a call while performing various quasi-normal operations on one of the test machines, and furthermore, it is surprising that the sequence at that time is confirmed. There was an effect that a bug could be found.

[0019]

As described above, the present invention has the following advantages. (1) Since the sequence of each mobile station during a call can be monitored, it is possible to test the sequence during a call between mobile stations in a call state. (2) A call can be made between actually connected mobile devices including a three-way call. (3) Since a combination of mobile devices such as a new model, an old model, and a competitor's model can be arbitrarily realized, it is easy to confirm the operation when developing a new model.
