DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a device for transmitting a message to a mobile terminal for transmitting message contents in preparation for a call failure due to a communication line interruption when communicating with a mobile terminal. 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 various proposals have been made in a realization system. Due to restrictions on the service area, calls cannot always be received. Therefore, such a service is provided because it is sufficiently anticipated that the calling party cannot make a call to the mobile terminal.
For example, Japanese Unexamined Patent Publication No. Hei 5-284224 discloses that when a mobile terminal moves out of a communication area including power-off, an incoming call to the mobile terminal is automatically connected to a voice mail device. When the mobile terminal returns to the communication area by performing proxy reception, a notification that voice mail is present is provided.
By receiving the notification, the mobile terminal subscriber who has received the notification can receive the incoming call message when out of the communication area.

[0003]

However, in such a conventional apparatus, when the mobile terminal returns from the state of being unable to receive a call, the mobile terminal on the receiving side listens to the registered voice mail. As the mobile terminal has been unable to receive calls for a long time and the amount of voice mail has increased, it has been impossible to take measures when the voice mail storage capacity is exceeded, and even if the mobile terminal is ready to receive calls, it is not possible to retrieve the received voice mail due to a call in progress. The response was undecided. In addition, when it is possible to predict in advance that the mobile terminal will run out of battery or to move out of the communication area, there is a problem that the mobile terminal has not taken measures when there is a message to be registered.

[0004] The present invention has been made in view of such a situation, and responds to a problem caused by an excess of voice mail storage capacity and a non-response of a message on the mobile terminal side in a response when a mobile terminal cannot receive a call. Things.

[0005]

In order to solve such a problem, a message transmitting method and a message transmitting apparatus according to the present invention are provided.

[0006]

The message from the subscriber to the mobile terminal is deleted when the mobile terminal does not answer a plurality of calls even if the mobile terminal is available. Also, when the mobile terminal is unlikely to be able to maintain a communication line from the mobile terminal to the subscriber, a message is registered and the subscriber can listen to the message by accessing it.

[0007]

FIG. 1 is a block diagram showing one embodiment of the present invention. A subscriber 1 communicates with a mobile terminal 5 through an interface operation with a radio network controller 3 having a base station 4 via a transmitting station 2. To achieve. 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 to receive a call. The voice mail device 9 is connected to the radio network controller 3, stores messages from the mobile terminal 5 and the subscriber 1 in the voice storage unit 6, activates the time setting unit 7 and the time management unit 8, and activates the mobile terminal. The voice mail processing between the subscriber 5 and the subscriber 1 is performed.

FIG. 2 and FIG. 3 are sequence charts showing the operation of this apparatus, and a series of operations are shown in two drawings. I have. The mobile terminal 5 transmits a message “voice message A” for the incoming call to the radio network controller 3 in preparation for the incoming call impossible state. The voice mail device 9 stores the message received via the radio network controller 3 in the mobile terminal side message 62 of the voice storage unit 6 (step S1).

At this time, if there is a request from the mobile terminal, the mobile terminal receives the mobile terminal calling time, the mobile terminal calling interval, and the subscriber message registration time. The data is accumulated in each block of the interval unit 72 and the transmission side message registration time unit 73 (steps S2, S3, S4). When the subscriber 1 makes a call while the mobile terminal 5 can receive a call (step S5), the radio network controller 3 calls the mobile terminal 5 as in a normal call (step S6), and the mobile terminal 5 responds. If you do (Step S
7) A call is made (step S8). Further, when the mobile terminal is out of the service area, the reception at the mobile terminal cannot be performed in the same manner as a general one.

[0010] Since the mobile terminal 5 is out of the communication range, it is in a call-disabled state. When the subscriber 1 makes a call in this state (step S9), the voice mail device 9 is activated and the voice storage unit 6 is activated. Is transferred to the subscriber 1 (step S10). Furthermore,
A voice message registration request is sent (step S11), and when there is a message that the subscriber 1 wants to convey 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 transmits the “voice message B” to the calling side message 6 of the voice storage unit 6.
1 and the received time is stored in the message registering timer 83 of the sending side of the time management unit 8.

The operation of FIG. 2 has been described above. Next, the operation of FIG. 3 will be described. When the base station 4 recognizes that the mobile terminal 5 has returned to the reception-enabled state, the base station 4 notifies the radio network controller 3 of the fact. As a result, the voice mail device 9 is activated and notifies the mobile terminal 5 that there is a received message. (Step S13-1).

At this time, the mobile terminal paging timer 81 of the time management unit 8 is operated, and a notification is made for the time set in the mobile terminal paging time unit 71. If the mobile terminal does not respond even after the time set in the mobile terminal call time section 71 elapses, the call is interrupted and the mobile terminal call interval timer 82 operates.

When the time T2 set in the mobile terminal call interval section 72 has elapsed since the previous call, the radio network controller 3 transfers the notification indicating that there is a received message again (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 radio network controller 3 notifies that there is a received message (step S13-1A). If the mobile terminal 5 does not respond, the radio network controller 3 transfers the notification indicating that there is a received 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 the received message a plurality of times, there is no response from the mobile terminal 5 and the elapsed time from the time when the “voice message B” is registered is set by the time setting unit 7.
T set in the subscriber message registration time section 73 of
If 3 has elapsed, the voice message B is deleted.

At this time, the message registration timer 8 of the calling side
3 manages the elapsed time based on the reception time and the notification start time of the presence of the received message, and compares it with the message registration time section 73 of the transmitting side to determine the 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 sender message 61, and the time management unit 8 may be provided.
The subscriber 1 is not limited to a fixed terminal, but may be a mobile terminal. However, when the subscriber 1 is a fixed terminal, it is desirable that the voice message A also registers the calling-side message registration time T3, and that if the call is not answered after being called a predetermined number of times, the recording is deleted. In the above description, the message content is described as a voice message, but this may be other data as long as the data can be stored and transferred.

[0017]

As described above, according to the present invention, a message can be registered when there is a possibility that the mobile terminal cannot maintain the line. Therefore, the registered message is transferred according to a request from a subscriber or the like. be able to. In addition, since a plurality of calls are made to the mobile terminal at predetermined intervals, even if the mobile terminal is busy, a message can be transferred when the call ends. And if there is no response even if the mobile terminal is repeatedly called multiple times, the message content will be deleted,
This has the effect that the problem of excess storage capacity can be solved.
