2. Description of the Related Art A PHS communication system using an onal handyphone system has been widely used. In a PHS communication system, when a mobile station (PS: Personal Station) makes a call request to a node (a base station (CS: Cell Station) or a PHS exchange), the node determines whether or not the node is busy. If the mobile station is busy, a busy signal indicating that the mobile station is busy is transmitted.

[0003] When the mobile station receives the busy signal transmitted by the node, the mobile station outputs a busy tone from the receiver, so that the user listens to the busy tone output from the receiver, and the user enters a busy state. It can recognize that it is.

[0004] By the way, in the related art, the node is not only in a busy state, but also in a case where, for example, the calling telephone number is an outgoing restricted telephone number which is a subject of the outgoing restricted call, A busy signal is transmitted to the mobile station even when the system rejects an outgoing call request that is not permitted, such as when the system is unregistered, or when a failure occurs. Therefore, the mobile station will output a busy tone from the receiver even if the system rejects an outgoing call request that is not permitted or if a failure occurs,
In response, the user will hear a busy tone.

[0005] Under such circumstances, in the conventional one,
There is a problem that the user cannot judge whether the user is busy, whether a call request not permitted by the system has been rejected, or whether a failure has occurred, only by listening to the busy tone.

Therefore, for example, if the user hears the busy tone and determines that the device is busy despite the occurrence of a failure, the user may perform unnecessary call operations many times. . Conversely, if the user hears the busy tone and determines that a failure has occurred despite the fact that the system is busy, the maintenance person who maintains the system will be informed that the failure has occurred. There is a risk of reporting.

The present invention has been made in view of the above circumstances, and has as its object to notify a mobile station of a reason for rejection when a node rejects a call request from a mobile station. An object of the present invention is to provide a wireless communication system, a node, and a mobile station that can allow a user using a mobile station to recognize a reason for rejecting a call request and thereby improve convenience.

The control circuit 31 stores a program, and controls the circuits 26 and 27, the keypad 28, the display 29, and the LED 30 by executing the program.

Next, the operation of the above configuration will be described with reference to FIGS. The premise is that the maintenance terminal 14 transmits a rejection reason notification command to any of the PHS exchanges (A) 2 to (C) 4 to notify a rejection reason notification function to any PHS exchange. Can be set, here,
It is assumed that the maintenance terminal 14 has set the rejection reason notification function in all the PHS exchanges (A) 2 to (C) 4. Hereinafter, the PHS exchange (A) 2 among the PHS exchanges (A) 2 to (C) 4 will be described as a representative.

Now, the mobile station 25 is within the range of the base station (A) 5, and the mobile station 25 makes a transmission request to the base station (A) 5 (step S1). 5 receives the transmission request from the mobile station 25, the base station (A) 5
It is determined whether or not it is busy (step S2). If it is busy, “YES” is determined in step S3, and a busy signal is transmitted to the mobile station 25.

When receiving the busy signal transmitted by the base station (A) 5, the mobile station 25 causes the receiver 34 to output a busy tone (step S4). This allows
By listening to the busy tone output from the receiver 34, the user using the mobile station 25 can recognize that the transmission request has been rejected due to the busy state of the base station (A) 5. become.

On the other hand, if the base station (A) 5 is not busy, it determines "NO" in step S3, transmits a transmission request to the PHS exchange (A) 2, which is a higher-order PHS exchange, and (A) 2, upon receiving the transmission request from the base station (A) 5, executes predetermined processing (step S).
5). Specifically, the PHS exchange (A) 2 first determines whether or not the outgoing telephone number is a valid telephone number (step S6).

Now, assuming that the outgoing telephone number is not a valid telephone number, for example, the outgoing telephone number is an outgoing restricted telephone number that is subject to outgoing call control, the PHS exchange
(A) 2 determines "NO" in step S7, and transmits a rejection reason indicating that the calling telephone number is a calling-restricted telephone number to the mobile station 25 through the base station (A) 5. When the mobile station 25 receives the rejection reason transmitted by the base station (A) 5, the mobile station 25 causes the receiver 34 to output sound information corresponding to the rejection reason (step S8).

In this case, the sound information output from the receiver 34 is different from the busy tone in the frequency band and the output pattern, so that the user using the mobile station 25 can output the sound information from the receiver 34. By listening to the sound information, it is possible to recognize that the outgoing call request has been rejected due to the outgoing telephone number being the outgoing restricted telephone number.

On the other hand, if the outgoing telephone number is a valid telephone number, PHS exchange (A) 2 determines "YES" in step S7, and then determines whether or not the contents of the outgoing call request are valid. (Step S9).

Now, assuming that the content of the outgoing call request is not valid and, for example, the mobile station 25 has not been registered in the system, the PHS exchange (A) 2 proceeds to step S10
Is determined to be “NO”, and the mobile station 25 sends the base station (A) 5
The mobile station 25 transmits a rejection reason indicating that the mobile station 25 has not been registered with the system. Then, the mobile station 25
Upon receiving the rejection reason transmitted by the base station (A) 5, the receiver 34 outputs sound information corresponding to the rejection reason (step S11).

In this case, the sound information output from the receiver 34 has a different frequency band and output pattern from the above-described busy tone and the sound information output in step S8, so that the mobile station 25 is used. The user
By listening to the sound information output from the receiver 34,
It is possible to recognize that the transmission request has been rejected because the mobile station 25 has not been registered in the system.

On the other hand, if the content of the outgoing request is valid, PHS exchange (A) 2 determines “YES” in step 10.
Is determined, and an outgoing call request is transmitted to the PHS exchange on the communication partner side (step S12). And PHS exchange (A) 2
Determines that the connection of the communication line between the mobile station 25 and the communication partner is successful, determines “YES” in step S13, and executes a call process (step S14).

On the other hand, the PHS exchange (A) 2
If the connection of the communication line between the communication partner and the communication partner fails due to, for example, a failure, the determination is "NO" in step S13, and the mobile station 25 rejects the connection through the base station (A) 5 indicating that the connection of the communication line has failed. Send reason. When receiving the rejection reason transmitted by the PHS exchange (A) 2, the mobile station 25 causes the receiver 34 to output sound information according to the rejection reason (step S15).

In this case, the sound information output from the receiver 34 is different from the busy tone described above, the sound information output in step S8, and the sound information output in step S11 in a frequency band and an output pattern. Thus, the user using the mobile station 25 hears the sound information output from the receiver 34 and recognizes that the transmission request has been rejected due to a failure in connection of the communication line due to, for example, a failure. It becomes possible.

In the above, the case where the receiver 34 outputs sound information according to the reason for refusal in the mobile station 25 has been described. However, the display 29 may output display information according to the reason for refusal. it can. That is, FIG.
As shown in (a) to (d), display information such as "base station busy", "calling telephone number NG",
Characters such as “system unregistered” and “connection failure” can also be displayed blinking on the display 29.

The PHS exchange (A) 2 is not limited to identifying the reason for rejection. If the base station (A) 5 has a function for identifying the reason for rejection, the base station (A) 5 The reason can also be identified.

Incidentally, in addition to the above-mentioned cases, the following cases may be rejected for the outgoing call request. For example, the mobile station 25 distinguishes each of them from the receiver 34.
Can output sound information or display information on the display 29.

When the authentication has failed. When the destination telephone number is a telephone number that has not been registered in the system. When the group pickup has failed to pick up. When another terminal has already picked up. If the terminal does not exist-If the system is restricted-If the call immediately before the caller has not been completely released-If there is a problem with the system-A function that is not permitted by the system Is requested ・ When calling the local phone number ・ When the receiving party is out of service area or the power is off

As described above, according to this embodiment, when the PHS exchange (A) 2 rejects the outgoing call request from the mobile station 25, the reason for rejection when rejecting the outgoing call request from the PHS exchange (A) 2 is as follows. Is transmitted, and when the mobile station 25 receives the rejection reason, the mobile station 25 notifies the rejection reason as sound information or display information. By judging the information, it is possible to recognize the reason for rejection, which is the reason for rejecting the transmission request, and thereby it is possible to improve convenience.

When the PHS exchange (A) 2 rejects an outgoing call request from the mobile station 25, if the node is busy, the outgoing call request not permitted by the system is rejected. In this case, the user using the mobile station 25 identifies each of them as a rejection reason, which is a reason why the outgoing request was rejected. The reason for refusal can be recognized separately.

The present invention is not limited to the above-described embodiment, but can be modified or expanded as follows. The PHS communication system may be any of a public system and an office system, and may be a private branch exchange (P
