Abstract

A remote call testing method is provided to be capable of remotely monitoring performance when originating/incoming calls of a desired base station are processed, thus the time required for testing calls is reduced. An operator terminal attempts call origination to the first terminal(S101). An MSC(Mobile Switching Center) where the first terminal is received conducts a paging process to the first terminal(S103). As the first terminal responds to the paging process, a speech path is established between the operator terminal and the first terminal(S105,S107). The first terminal attempts to originate a call to the second terminal(S109). As the second terminal responds to the call, a speech path is established between the first terminal and the second terminal, so that a speech path is established between the operator terminal and the first/second terminals(S111,S113).

The present invention relates to a call test method, and more particularly to a remote call test method for remotely measuring the quality on the call path between mobile communication terminals.

Currently, when a call quality abnormality is confirmed in a mobile communication system or a service complaint is received by a subscriber, an operator directly goes to a site where a problem occurs and performs a call test. Accordingly, there is a problem that the call test takes a lot of time unnecessarily and the process is cumbersome.

One way to solve this problem is to ask the subscriber to test the call and receive the results to check whether there is any abnormality and details of the call quality, which requires the cooperation of the subscriber. There is a disadvantage that further increases subscriber complaints.

In addition, there is a method of installing a base station test unit (BTS Test Unit; BTU) having a communication module in the base station to remotely check the state of the base station, and the operator is connected to the BTU remotely to check the state of the base station.

1 is a diagram illustrating a general remote call test method.

As shown, the base station (BTS, 20) is provided with a BTU (22), the operator terminal 10 to make a call to the BTU 22 through the switch (MSC, 40) and the base station controller (BSC, 30) As the request signal is transmitted, the BTU 22 attempts to call the operator terminal 10 to establish a call path.

After the call path is set up as described above, the operator terminal 10, which is the called party, loops back the test call call to check the status of the vocoder, the channel card, and the like of the corresponding base station 20.

However, in the current call test method using the BTU, it is difficult to detect a problem in the base station because the base station state can be confirmed only from the called party's position and the base station's state cannot be confirmed from the calling party's point of view.

The present invention has been made to solve the above problems and disadvantages, there is a technical problem to provide a remote call test method that can check the state of the base station in the remote and the case of both the calling party and the called party.

The present invention for achieving the above technical problem is the step of the operator terminal attempts to make a call to the first terminal; Performing a paging to the first terminal by the exchange accommodated by the first terminal; Setting up a call path between the operator terminal and the first terminal as the first terminal responds; The first terminal attempting to make a call to a second terminal; And a call path is established between the first terminal and the second terminal as the second terminal responds, and a call path is established between the operator terminal, the first terminal, and the second terminal.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a flowchart illustrating a remote call test method according to the present invention.

As shown, the operator tries to make a call using the operator terminal (S101). In this case, the call request signal includes a first terminal number and a second terminal number, and the first terminal may be a terminal accommodated in a base station to be measured or a BTU installed in a base station to be measured. In addition, the second terminal may be a terminal located in a section requiring inspection from the base station to be measured. That is, the operator attempts to make a call for monitoring the call path set between the first terminal and the second terminal.

The originating attempt of the operator terminal is transmitted to the exchange accommodating the first terminal, and the exchange checks the called terminal number, that is, the first terminal number, and performs paging to the corresponding terminal (S103). Here, the exchange transmits a message requesting to attempt transmission to the second terminal number and the second terminal when performing paging to the first terminal.

Thereafter, when the first terminal transmits the response message for paging of step S103 to the exchange (S105), that is, when the first terminal responds, a call path is established between the operator terminal and the first terminal (S107).

Next, the first terminal attempts to make a call to the second terminal according to the second terminal number and the call origination request message received in step S103 (S109), and the exchange in which the second terminal is accommodated makes paging to the second terminal. When the second terminal responds with the execution (S111), a call path is established between the first terminal and the second terminal (S113).

In this way, a call path is established between the operator terminal and the first terminal, the first terminal, and the second terminal, and as a result, a call is initiated between the operator terminal, the first terminal, and the second terminal. The operator terminal may monitor not only paging signals and ringback tones generated in the process of connecting the first terminal and the second terminal in step S109 and step S111, but also announcements sent to process other additional services. .

Accordingly, the performance of the base station configuration equipment such as the vocoder state, the channel card state, etc. of the base station in which the first terminal is accommodated and the base station in which the second terminal is accommodated can be tested, as well as a call between the first and second terminals. Quality, transmit and receive power can also be measured.

Meanwhile, the second terminal may be a base station (first base station) in which the first terminal is accommodated or a subscriber station accommodated in another base station except the first base station, or may be a BTU installed in other base stations other than the first base station. .

As such, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without changing the technical spirit or essential features thereof. Therefore, the above-described embodiments are to be understood as illustrative in all respects and not as restrictive. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.

According to the present invention, it is possible to remotely monitor the performance of the desired base station during outgoing and incoming call processing, thereby reducing the time required for call testing and avoiding the trouble of traveling for call testing. .

In addition, since the operator terminal can test the performance of the base station, which was previously available only for the called party's position, from both the called party and the calling party, it is possible to more accurately understand the performance of the base station. There is an advantage to deal with.
