Abstract

PURPOSE: To reduce a speech call loss by inhibiting automatically the transmission of an information collection signal before the processing by a mobile communication exchange reaches its limit. CONSTITUTION: An automatic answering message inquiry signal 23 is sent automatically in succession to position registration processing at application of power to a mobile communication terminal equipment 13. A mobile communication exchange receiving the signal 23 makes inquiry of terminal information database 16 and receives a reply representing the presence of a message. A specific bit 25 in a reply signal 24 to report presence of the message to the terminal equipment 13 is set to '1' when a processing signal traffic amount of the exchange 15 is higher than a threshold level X and set to '0' when smaller. The terminal equipment 13 stores the level of the specific bit 25 in the received signal 24 to the storage section 21. When the bit is '1' in the storage section the transmission of the automatic answering message inquiry signal is inhibited and when '0', the transmission is allowed.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention performs call processing of a mobile communication terminal by referring to information in a terminal information database through the mobile communication switch, and by a signal for collecting information from the mobile communication terminal, The present invention relates to a method of collecting information in mobile communication that enables a service of notifying a corresponding subscriber of the presence or absence of information, for example, the presence or absence of an answering message in a voice storage device in a network, through a terminal information database, and a mobile communication terminal used for the method. .

[0002]

2. Description of the Related Art As one of services of a mobile communication network, when the power of the mobile communication terminal is off, or when the mobile communication terminal is located in an area (out of service area) where the radio wave of the mobile communication network does not reach, When there is an incoming call during a call, there is an answering machine service that accumulates an answering machine message for the called party in a voice storage device. In this answering machine service, in order to promptly notify the presence / absence of an answering machine message to the mobile communication terminal, it is necessary to have a function to inform the terminal of the presence / absence of an answering machine message from the network when the mobile communication terminal is powered on or when the location is registered. . In the conventional technology, the mobile communication terminal sends an information collection signal to the mobile communication switching system in order to inquire about the presence or absence of an answering machine message at the time of power-on and location registration, and the presence or absence of an answering machine message is determined by a response signal from the mobile communication switching system. Had decided.

A processing procedure for inquiring about the presence or absence of an answering machine message by the information collection signal from the mobile communication terminal will be described with reference to the drawings. An outline of this type of mobile communication system is shown in FIG. The voice storage device 11 is connected to the exchange 12 through a line, the mobile communication terminal 13 is connected to the wireless base station 14 through a wireless communication line, and the wireless base station 1
4 is connected to a subscriber's mobile communication exchange 15 through a line, the mobile communication exchange 15 is connected to a switch 12 through a line, and the exchanges 12 and 15 are respectively connected to a terminal information database (so-called home memory) 16 through a control line. . Other lines other than the connection between the terminal information database 16 and the exchanges 12 and 15 are composed of communication lines and control lines.

The voice storage device 11 stores the number of messages, message reception time, and the number of messages for each subscriber (mobile communication terminal) who has a contract for an answering service.
Message information and the like are stored. The terminal information database 16 stores, for each subscriber (mobile communication terminal), its zone information, contract service information, message presence / absence information indicating whether or not a message for the subscriber is stored in the voice storage device 11. Remembered

In this system, when a call is made to a mobile communication terminal outside the service area or a mobile communication terminal in a power-off state, these mobile communication terminals are used as an answering machine service. If subscribed, the caller can record an answering machine message in the voice storage device 11. That is, as shown in FIG. 6, when the mobile communication terminal 13 is turned on (S1), the mobile communication terminal 13 performs location registration processing to notify the mobile communication network of its own location (S2), and then An information collection signal (answering message inquiry signal) is transmitted from the mobile communication terminal 13 to the mobile communication exchange 15 (S3), and the mobile communication exchange 15 having received the information accesses the terminal information database 16 (S4) to perform the mobile communication. The message presence / absence information of the terminal 13 is read out and sent back (S5). If the response message presence / absence information indicates that there is no message, the mobile communication exchange 15 sends an answering message inquiry response signal indicating no message to the mobile communication terminal 13. Send (S
6) If the response message presence / absence information indicates that there is a message, an answering machine message inquiry response signal indicating the presence of the message is sent to the mobile communication terminal 13 (S7).
The mobile communication terminal 13 displays the content of the received answering machine message inquiry response signal, that is, the presence or absence of the answering machine message on its display (S8).

[0006]

It is expected that the number of services for transmitting various kinds of information by transmitting such an information collection signal from a mobile communication terminal will increase. In that case,
It is conceivable that the number of information collection signals increases and the signal traffic processed by the mobile communication exchange becomes temporarily excessive and exceeds the processing capacity. Then, the call and the facsimile, which are the original functions of the mobile communication network, perform the calling process and the incoming call process between the mobile communication terminal and the passive mobile communication terminal or the fixed communication terminal, and connect them to each other, and the like. Communication (hereinafter referred to as call processing communication) cannot be temporarily performed.

In the current mobile communication terminal, it is not possible to judge whether or not the terminal itself subscribes to an answering machine service, for example, and the power is turned on even for a mobile communication terminal not contracted for the answering machine service. In this case, after the location registration processing, the answering machine message inquiry signal is automatically transmitted. As a result, useless information collection signals are transmitted, and useless processing is performed in the mobile communication network, which may prevent the effective processing of call processing signals from being performed during traffic congestion.
It is also possible to store in the ROM whether or not the mobile phone itself has an answering machine service contract, for example, but if you make an answering machine service contract after subscribing to the mobile communication network, the mobile communication terminal will be updated one by one. , It is necessary to bring it to the operator of the mobile communication network in order to store it in the ROM, and even if a telephone answering service contract is made at the time of subscribing to the mobile communication network, it is possible to write in the ROM, for example. It must be a business office, and where it does not have the capability, it must take the mobile communication terminal to where it can. In view of these points, at present, the mobile communication terminal itself cannot determine whether or not it has an answering machine service contract.

When the number of services for obtaining information by the information collecting signal other than the call processing communication increases, there is a possibility that the processing of the call processing communication by the information collecting signal is temporarily disabled as described above.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the invention of claim 1 is applied to collect an answering machine message as collected information will be described below with reference to the drawings. An outline of a mobile communication system to which the information collecting method of the present invention is applied is shown in FIG. 1, and parts corresponding to those in FIG. The mobile communication terminal 13 is provided with an information collection availability storage unit 21, and this storage unit 21 stores information “1” indicating that regulation is being performed or information “0” indicating that regulation is not being performed. Further, the subscriber mobile communication exchange 15 monitors whether or not the amount of signal traffic processed by the exchange 15 is a threshold value X or more, and the threshold value X
Is smaller than the processing limit of the exchange 15, but relatively close to this.

The storage content of the storage unit 21 of the mobile communication terminal 13 is currently "0" during non-regulation, and the mobile communication exchange 15
It is assumed that the processing signal traffic amount of 1 has exceeded the threshold value X. In this state, in the same manner as described above, for example, the mobile communication terminal 13 is turned on and the location registration processing is performed based on this (omitted in FIG. 2), and then the answering machine message inquiry signal (information collection signal) 23 is transmitted. The mobile communication exchange 15 which has been sent (S3) and has received this information collection signal issues an information read request to the terminal information database 16 (S4), as in the conventional case, and the mobile communication terminal uses the terminal information database 16 to read the information. The answering machine message presence / absence information for 13 is received as an information read response (S5). When the answering message inquiry response signal 24 is sent to the mobile communication terminal 13 based on this message presence / absence information, as described above, the mobile communication exchange 15 has a processing communication traffic amount exceeding the threshold value X, so that the response signal 1-bit information collection permission / inhibition information 25 is added to 24 as information "1" indicating the regulation and transmitted (S
9).

The mobile communication terminal 13 which has received the response signal 24 sets the content stored in the information collection availability storage section 21 to "1" during regulation (S10). Further, the mobile communication terminal 13 prohibits sending of an answering machine message inquiry signal (information collection signal) when the storage content of the storage unit 21 is "1" being restricted (S11). In this way, the traffic volume of the information collection signal in the mobile communication network decreases, and the possibility that call processing communication cannot be established due to traffic congestion is reduced.

When the amount of signal traffic to be processed in the mobile communication exchange 15 becomes equal to or less than the threshold value X, the call processing signal 26, that is, a signal based on the call origination processing or the call reception processing, which is subsequently performed in the mobile communication exchange 15, is detected. The 1-bit information collection permission / inhibition information 27 is added to “0” indicating cancellation, and added to the mobile communication terminal 13 (S12). The addition of "0" to the information collection availability information 27 may be performed only for the call processing signal for the mobile communication terminal that previously sent the information collection availability information 25 as "1". Since the management for that is required, the call processing signal 2
The specific bits 6 are used as the information collection availability information 27, and if the signal traffic amount is equal to or less than the threshold value X, the information collection availability information 27 is canceled for the call processing signal 26 transmitted to any mobile communication terminal. It may be sent as "0".

The mobile communication terminal 13 that has received the call processing signal 26 sets the storage content of the storage unit 21 to "0" during non-regulation (S13). Therefore, thereafter, the information collection signal can be transmitted from the mobile communication terminal 13 (S14). As is clear from the above description, the mobile communication terminal 13 (invention of claims 10 and 11) according to the present invention, as shown in FIG. 3, generates a request to send an information collection signal (S15).
The information collection availability storage unit 21 is read (S16), and it is checked whether the read content is "1" being restricted (S1).
7) If it is "1", sending of the information collection signal is prohibited (S18), and if the read content is "0" during non-regulation, the information collection signal is sent (S19).

Further, the information collectability information 27 is received (S
20) and the information 27 are stored in the information collection availability storage unit 21. In the above description, when the mobile communication exchange 15 receives the information collection signal 23, it makes a read request to the terminal information database 16 even if the signal traffic amount is equal to or more than the threshold value X, and the response result is used as the response signal 24 for mobile communication. When the signal traffic amount is sent to the terminal 13 but the signal traffic amount is equal to or more than the threshold value X, the information collection availability information 25 is immediately sent without making a read request to the terminal information database 16.
The response signal 23 with the restriction “1” may be sent to the mobile communication terminal 13.

When the amount of signal traffic exceeds the threshold value X, the mobile communication exchange 15 adds a restriction "1" as the information collection permission / inhibition information 25 to a specific bit of the call processing signal to any mobile communication terminal. May be sent. That is, the mobile telecommunication exchange 15 sets 1 bit as the information collection enable / disable information for the specific bit for any call processing signal, and regulates "1" when the signal traffic amount is equal to or more than the threshold value X and is less than the threshold value. The release “0” may be always transmitted.

Further, when the amount of signal traffic in the mobile communication exchange 15 falls from the threshold value X to the threshold value X or less, the information collection permission / inhibition information 27 is released through the common control channel commonly received by each mobile communication terminal to "0". The content stored in the storage unit 21 of the mobile communication terminals 13 may be simultaneously set to the non-restricted state. By doing so, it is possible to prevent the transmission of the information gathering signal from being forbidden indefinitely depending on the mobile communication terminal even if the call processing signal generated thereto is small.

Further, not only when the restriction is released from the mobile communication exchange 15, for example, as shown in FIG. 3B, when the storage section 21 of the mobile communication terminal 13 is set to "1" during restriction (S23), thereafter, it is appropriate. Time passes (S2
4) Alternatively, the mobile communication terminal 13 itself may automatically rewrite the storage content of the storage unit 21 to "0" during non-regulation (S25). Even in this case, since the communication traffic volume of the mobile communication exchange 15 temporarily exceeds the threshold value X, when the information collection signal 23 is transmitted from the mobile communication terminal 13, the mobile communication exchange 15 It is possible that the amount of communication traffic is below the threshold value X.

A proper time after the storage section 21 is set to "1" during regulation means that the predicted fluctuation of the signal traffic amount, that is, the predicted continuous threshold value X.
It is after about the above time, and this may be set to a predetermined time by a timer or the like, and when it becomes a certain process in the regular program process performed in the mobile communication terminal 13, it is not regulated “0. It may be rewritten as "".
Further, when the transmission of the information collection signal 23 is prohibited as shown by the dotted frame in FIG. 3A (S18), a predetermined time is waited for (S26), and when the predetermined time elapses, the storage unit 2
1 may be rewritten to "0" during non-regulation (S27).

Next, an embodiment of the method of the invention of claim 8 will be described with reference to FIG. 4 in the case where it is applied to collecting answer message presence / absence information. The mobile communication terminal 13 not contracting the answering service is turned on for the first time (S
1) Based on this, location registration processing is performed (S3), and then an answering machine message inquiry signal which is the information collection signal 24 is sent to the mobile communication exchange 15 (S3). The mobile communication exchange 15 makes an inquiry to the terminal information database 16 as to whether or not the mobile communication terminal 13 is permitted to have an answering service (S4). Although the response signal is transmitted from the terminal information database 16 to the mobile communication exchange 15 (S5), when the mobile communication terminal 13 is the non-acceptance service (non-subscriber), the terminal information database 16 receives the response signal. Bit 1 (restricted) indicating that the answering service is not permitted, that is, the information collection permission / prohibition information 29 is set to regulation “1” and transmitted (when the answering service is permitted, the information collection permission / prohibition information 29 is set). Release "0" and send.) The mobile telecommunication exchange 15 receiving this signal sends an inquiry response signal 2 with an answering machine message.
The information collection permission / inhibition information 25 of the specific bits of 4 is set to the regulation “1” and transmitted to the mobile communication terminal 13 (S6). The mobile communication terminal 13 looks at the received answering message inquiry response signal 24 and writes "1" (restricted) in the internal storage unit 21 (S10). Therefore, after that, transmission of the information collection signal is prohibited. By these operations, the information collection signal from the person who does not allow the answering service is regulated, the information collection signal is not sent unnecessarily, and the communication network is not wastefully processed so efficiently.

When the mobile communication terminal 13 subscribes to the answering machine service, the fact that the answering machine service is permitted is registered in the terminal information database 16 (S16). Then, for example, a call processing signal 31 other than the information collection signal for the mobile communication terminal 13 is generated, and when this reaches the terminal information database 16, the terminal information database 16 is generated.
Then, the state transits to the inquiry possible state. The call processing signal 31
A cancellation "0" is transmitted as a specific bit of the response signal 32 for the information collection permission / inhibition information 33 (S19). Receiving this, the mobile switching center 15 sets bit 0 (no restriction) indicating the answering service permission in the call processing signal 34 directed to the mobile communication terminal 13, that is, cancels the information collection permission / inhibition information as "0". The mobile communication terminal 13 which has transmitted (S20) and received it rewrites the internal storage unit 21 from "1" (restricted) to "0" (no restriction), seeing this information collection availability information ( S21), an information collection signal is sent out, and in this example, an answering machine message inquiry is possible. After this operation, the mobile communication terminal 13 transmits an answering service inquiry signal which is an information collection signal.

In the above description, the present invention is applied to the collection of the answering machine message presence / absence information, but it can be applied to other information collection as well, and in this case, the information is automatically transmitted in accordance with some processing such as power-on or location registration. It is not limited to the case where the collection signal is sent out, but the operator can appropriately and voluntarily.
For example, it can be applied to a case where desired information is collected by key operation. The answering machine message may also be configured such that the operator can freely send a collection signal by key operation. In these cases, according to the present invention, the transmission of the information collection signal is automatically prohibited when the processing signal traffic amount of the mobile communication switch is equal to or greater than the threshold value. It should be noted that, due to the increase in the traffic volume, the transmission of the information collection signal is prohibited,
When the transmission of the information collection signal to the non-contract service terminal is both prohibited, the two methods are correctly executed by distinguishing by the bit position of the information collection availability information.

[0029]

As described above, according to the inventions of claims 1 to 7, the transmission of the information collection signal is automatically prohibited before the processing of the mobile communication exchange reaches the limit, and the call processing call is called. There is no risk of increased loss. Further, according to the inventions of claims 8 and 9, the transmission of the information collection signal from the information collection service non-contracted terminal is automatically prohibited, and the useless transmission of the information collection signal is prohibited, and the mobile communication network is more efficient accordingly. Used for.
