Abstract

PURPOSE: To cope with a harmful effect by voice mail storage capacity over and the message non-response of a mobile terminal side in responses at the mobile terminal call termination impossible time. CONSTITUTION: Since a message is registered in a radio channel control station 3 when there is a possibility that the mobile terminal 5 can not maintain a channel, the registered message is transferred by a request from a subscriber 1 or the like. Also, since the radio channel control station 3 calls the mobile terminal 5 for plural times with a prescribed interval, even when the mobile terminal 5 is during communication, the message is transferred when the communication is ended. Then, since the radio channel control station 3 eliminates message contents when no response is present even through the mobile terminal 5 is repeatedly called for the plural times, the problem of storage capacity over is dissolved as well.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a message transmitting method and a message transmitting device for transmitting a message content to a mobile terminal in case of communication failure with a mobile terminal to prevent a call from being interrupted due to communication line interruption or the like. is there.

[0002]

2. Description of the Related Art An answering machine and a voice mail service in a telephone exchange system are currently being implemented and many proposals have been made for realizing them. Especially, in the case of a telephone for mobile communication, battery drive time and communication are required. Due to the restrictions of the service area, it is not always possible to receive an incoming call. Therefore, such a service is provided because it is sufficiently expected that the subscriber who originated the mobile terminal cannot make a call.
For example, the one disclosed in Japanese Unexamined Patent Publication No. 5-284224 automatically connects an incoming call to the mobile terminal to a voice mail device when the mobile terminal moves out of the communication range including the power-off. When the mobile terminal returns to the communication area by performing proxy reception, it notifies that there is voice mail.
The mobile terminal subscriber who has received the notification can receive the incoming call message outside the communication range by taking out the voice mail.

[0003]

However, in such a conventional apparatus, when the mobile terminal recovers from the state in which the incoming call is disabled, the mobile terminal on the called side listens to the registered voice mail. , As the number of voice mails increased as the mobile terminal continued to be unable to receive calls, it was not possible to take out the received voice mails due to a call when the voice mail storage capacity exceeded The action to be taken was uncertain. In addition, there is a problem that when the mobile terminal can predict in advance that the battery will run out of the communication range or when the mobile terminal will move out of the communication range, the mobile terminal does not take measures when there is a message to be registered.

The present invention has been made in view of such a situation, and in the response when the mobile terminal cannot receive an incoming call, it is arranged to deal with a harmful effect due to the excess of voice mail storage capacity or a non-response of a message on the mobile terminal side. It is a thing.

[0005]

In order to solve such a problem, the invention according to claim 1 provides a method in which after the communication line is restored, there is no response even if the mobile terminal is called a plurality of times at predetermined time intervals. Is to delete the message contents after a predetermined time. According to the invention of claim 2, in the invention of claim 1, when it is predicted that the mobile terminal cannot maintain the communication state, the content of the message sent from the mobile terminal is stored in the radio network controller and requested by the subscriber. At that time, the content of the message was transmitted. According to the invention of claim 3, a voice storage unit for accumulating message contents of the mobile terminal and message contents from the subscriber, a calling time for notifying the mobile terminal of the presence of the message, a time interval for repeating the notification, and The time setting unit that sets the time until message deletion to the mobile terminal, the ringing time measurement when notifying the mobile terminal that there is a received message and the time interval measurement when repeating the notification and the mobile terminal not It is provided with a time management unit for measuring a response time and a radio network controller for confirming whether or not the mobile terminal exists within the communication range.

[0006]

If the mobile terminal is not ready to answer a call even when the mobile terminal is ready to answer, the message from the subscriber to the mobile terminal is deleted. Further, when the mobile terminal is unlikely to be able to maintain the communication line from the mobile terminal to the subscriber, a message is registered and the subscriber can hear the message by accessing it.

[0007]

FIG. 1 is a block diagram showing an embodiment of the present invention, in which a subscriber 1 talks with a mobile terminal 5 through an interface operation with a radio network controller 3 having a base station 4 via a calling station 2. To realize. The base station 4 calls and communicates with the mobile terminal 5 and informs the radio network controller 3 whether or not the mobile terminal 5 is ready for incoming call. The voice mail device 9 is connected to the radio network controller 3, stores a message from the mobile terminal 5 or the subscriber 1 in the voice storage unit 6, or activates the time setting unit 7 and the time management unit 8 to activate the mobile terminal. 5 and subscriber 1 perform voice mail processing.

FIG. 2 and FIG. 3 are sequence charts showing the operation of this apparatus, which shows a series of operations in two drawings, but are described separately in two drawings due to the size limitation of the drawings. There is. The mobile terminal 5 sends a message "voice message A" for the incoming call to the radio network controller 3 in preparation for the incoming call disabled state. The voice mail device 9 stores the message received via the wireless line control station 3 in the message 62 on the mobile terminal side of the voice storage unit 6 (step S1).

At this time, if there is a request from the mobile terminal side, the mobile terminal calling time, the mobile terminal calling interval, and the subscriber message registration time are received, and the mobile terminal calling time portion 71 and the mobile terminal calling time of the time setting portion 7 are respectively received. It is accumulated in each block of the interval section 72 and the originating side message registration time section 73 (steps S2, S3, S4). When the subscriber 1 makes a call while the mobile terminal 5 is ready to receive a call (step S5), the radio network controller 3 calls the mobile terminal 5 (step S6) as in a normal call, and the mobile terminal 5 responds. If you do (step S
7) and make a call (step S8). Further, when the mobile terminal is out of the communication range, it is the same as the general one that the mobile terminal cannot make an incoming call.

Since the mobile terminal 5 is out of the communication range, the mobile terminal 5 is in an incoming call impossible state. When the subscriber 1 makes a call in that state (step S9), the voice mail device 9 is activated and the voice storage unit 6 is activated. The "voice message A" stored in is transferred to the subscriber 1 (step S10). Furthermore,
When a voice message registration request is sent (step S11) and the subscriber 1 has a message to be transmitted to the mobile terminal 5,
The "voice message B" is transferred to the radio network controller 3 (step S12). Then, the voice mail device 9 sends “voice message B” to the message 6 on the calling side of the voice storage unit 6.
The received time is stored in the sender side message registration timer 83 of the time management unit 8.

The above is the description of the operation of FIG. 2, and next, the operation of FIG. 3 will be described. When the base station 4 recognizes that the mobile terminal 5 has returned to the incoming-call ready state, the base station 4 notifies the radio network controller 3 of the fact. This activates the voice mail device 9 and notifies the mobile terminal 5 that there is a received message. (Step S13-1).

At this time, the mobile terminal calling timer 81 of the time management unit 8 is activated to notify the mobile terminal calling time unit 71 of the time set. If the mobile terminal does not respond even after the time set in the mobile terminal calling time section 71 has elapsed, the call is interrupted and the mobile terminal calling interval timer 82 operates.

When the time T2 set in the mobile terminal calling interval section 72 has elapsed since the last call, the radio network controller 3 transfers again the notification that there is a received message (step S13-2). If the notified mobile terminal 5 responds to the message reception (step S14), the voice mail device 9 directs the voice message B stored in the caller side message 61 of the voice storage unit 6 to the mobile terminal 5. Transfer (step S15).

Next, the case where the mobile terminal 5 does not respond to the message reception will be described. When the mobile terminal 5 returns to the communication range, the wireless line control station 3 notifies that there is a received message (step S13-1A). When the mobile terminal 5 does not respond to it, the radio network controller 3 transfers the notification of the reception message again after the set time T2 of the mobile terminal calling interval unit 72 (step S13-2A). Even if the mobile terminal 5 is notified of the notification of the presence of a received message a plurality of times in advance, there is no response from the mobile terminal 5, and the elapsed time from the time when the "voice message B" is registered is the time setting unit 7
Time T set in the subscriber message registration time section 73 of
When 3 has passed, the voice message B is deleted.

At this time, the sending side message registration timer 8
3 manages the elapsed time according to the reception time and the notification start time with the received message, and compares it with the originating side message registration time section 73 to determine message deletion.

When a plurality of subscribers register a voice message in the mobile terminal 5, a plurality of blocks of the voice storage unit 6, the caller side message 61, and the time management unit 8 may be provided.
The subscriber 1 is not limited to a fixed terminal, but can be a mobile terminal. However, it is desirable that when the subscriber 1 is a fixed terminal, the voice message A also registers the calling side message registration time T3, and the record is deleted when the subscriber 1 does not respond even after calling a predetermined number of times. In the above description, the message content is described as a voice message, but other data may be used as long as the data can be stored and transferred.

[0017]

As described above, according to the present invention, a mobile terminal can register a message when there is a possibility that the line cannot be maintained. Therefore, the registered message is transferred in response to a request from a subscriber. be able to. Further, since the mobile terminal is called a plurality of times at predetermined intervals, it is possible to transfer the message when the call ends, even when the mobile terminal is talking. And if there is no response even if you call the mobile terminal multiple times repeatedly, the message content is deleted, so
This has the effect of solving the problem of excess storage capacity.
