Abstract

<P>PROBLEM TO BE SOLVED: To overcome a problem that the voice signals via voice signal communication are limited to one-to-one real-time communication and time-shift distribution (re-hearing through time-shift) to many specified telephone sets is impossible. <P>SOLUTION: The problem can be overcome by recording voice signals via voice signal communication, originating the voice signals only to the specified many telephone sets registered previously, and distributing the voice signals to these telephone sets. Time-shift can be enabled while keeping secrecy by storing the contents of voice signals recorded through voice signal communication and distributing such contents only to the requests from the specified many telephone sets. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to voice communication, and is a system and method for transmitting a recorded voice signal only to a specific number of telephones and enabling time shift (listening again at different times).

  Currently, the penetration rate of telephones, including mobile phones, has reached the point where one person owns multiple devices. There are various types of services for mobile phones, and it is possible to send and receive character information and image data other than audio signals. (Figure 1)

  Young people have an unprecedented information-oriented society environment, but it is very difficult for elderly people to master advanced services. In the mountainous areas, there are not a few homes where mobile phones are not connected.

  There is currently no mechanism for simply sharing information by voice communication.

  Conventional voice communication can be performed only one-to-one and in real time. When distributing voice communication to a specific number, it is necessary for a person who distributes voice to perform one-to-one communication for the specific number of times.

On the other hand, in the Internet, there is a system capable of multicasting (distribution to a specific number of people).
JP 2002-26987 A

  The problem to be solved is that conventional voice communication enables multicast (distribution to a specific number of people) and time shift (re-listening at different times), and realizes one-to-many distribution in voice communication. There is.

  Further, it is possible to use multicast (distribution to a specific number of people) and time shift (listen again at different times) with a telephone set with a telephone number without using a multicast address on the Internet.

  The present invention uses a telephone number of a specific large number of telephones and a group representative telephone number composed of a specific number of telephones, and only the telephone numbers of a specific large number of telephones registered in advance make and receive calls to the group representative telephone number. The main feature is to record and play back audio signals via voice communication. (Figure 2)

  According to the present invention, a recorded voice signal can be transmitted to a large number of pre-registered telephones by calling and recording from a large number of pre-registered telephones to the group representative telephone number. (Figure 2)

  A large number of telephones registered in advance can listen to audio signals distributed to the same group again at different times (time shift).

  With this function, it is possible to provide a mechanism for simply sharing information using voice communication.

  The block diagram for implementing Claim 1 and Claim 2 is shown. FIG. 2 shows the basic configuration of this system. FIG. 3 is a group management table for grouping telephone numbers of a specific number of telephones. FIG. 4 is a distribution management table for managing the distribution state to a specific number of telephones.

An arbitrary plurality of switches 100, registration management servers 200, and distribution servers 300 in FIG. 2 can be installed, and line processing, search processing, and information update processing can be executed simultaneously in parallel.

  Claim 1 will be described in detail with reference to the drawings.

  Taking the group management table of FIG. 3 as an example, the telephones 10, 20, and 30 of FIG. 2 belong to the group representative number 1 and belong to a specific number of telephone groups. Telephones other than the telephones 10, 20, and 30 do not belong to the group representative number 1.

  A number of specific telephones can be registered in the group representative number of the group management table of FIG.

  The switch 100 in FIG. 2 is a switch that can make and receive calls with the group representative number in the group management table in FIG.

  When the telephone 10 in FIG. 2 makes a call to the group representative number 1, the exchange 100 receives the group representative number 1 and connects the line to the distribution server 300.

  The distribution server 300 in FIG. 2 notifies the group management number 1 and the telephone number 10 of the telephone 10 to the registration management server 200.

  The registration management server 200 in FIG. 2 searches the group representative number 1 of the group management table 201 for the telephone number 10 of the telephone in the group, and notifies the distribution server 300 of the result.

  The distribution server 300 in FIG. 2 determines that the distribution server 300 and the exchange 100 are connected to a specific number of telephones when the telephone number 10 of the telephone in the group exists in the group representative number 1 of the group management table 201 based on the search result. The use of the system related to voice distribution and time shift is permitted.

  The distribution server 300 in FIG. 2 disconnects the line when the telephone number 10 of the telephone in the group does not exist in the group representative number 1 of the group management table 201 based on the search result. Then, the disconnection of the line of the distribution server 300 is detected, and the same line of the exchange 100 is disconnected. In this case, the use of the system relating to voice distribution and time shift between a large number of specific telephones is not permitted.

  When the distribution server 300 in FIG. 2 is permitted to use the system, the distribution server 300 causes the registration management server 200 to send voice data 301 addressed to the group representative telephone number 1 in the distribution management table 202 and the telephone number 10 of the distribution destination telephone. Request the search process to see if exists.

  As a result of the search by the registration management server 200 in FIG. 2, when the audio data 301 exists, the distribution server 300 notifies the telephone 10 that the audio data 301 exists. When the telephone 10 does not transmit an arbitrary number, the recorded voice data 301 of claim 2 is distributed. When the telephone 10 transmits an arbitrary single-digit number, voice recording processing of the voice data 301 is performed.

  As a result of the search by the registration management server 200 in FIG. 2, when the audio data 301 does not exist, the audio recording process of the audio data 301 is performed.

  The telephone 10 permitted to use the system in the distribution server 300 in FIG. 2 records a message for the telephone group belonging to the group representative number 1, stores it as the voice data 301 in the distribution server 300, and disconnects the line. The exchange 100 detects the disconnection of the distribution server 300 and disconnects the same line of the exchange 100.

  A plurality of audio data 301 of the distribution server 300 in FIG. 2 can be registered.

  In order for the distribution server 300 of FIG. 2 to distribute the audio data 301 to the telephones 20 and 30 having the telephone numbers belonging to the group representative number 1 of the group management table 201, the distribution server 300 Request registration to the distribution management table 202. The items to be registered are the items in FIG.

  The distribution server 300 in FIG. 2 periodically checks the distribution status of the distribution management table 202 to the registration management server 200. If “undistributed” exists, the distribution server 300 passes the switch 100 to the telephone number of the distribution destination telephone. To send.

  In this case, the caller telephone number from the exchange 100 is transmitted from the group representative telephone number in the group management table of the distribution management table 202. In this example, the caller telephone number is 1.

  When the telephone set 20 is “undelivered”, the distribution server 300 tries to call the telephone set 20 again via the exchange 100. The number of outgoing calls can be arbitrarily changed by distribution server 300. The transmission time interval of the distribution server 300 to the same telephone can be arbitrarily changed by the distribution server 300.

  When the telephone 20 has not received an arbitrary number of times, the distribution server 300 sends to the registration management server 200 the group representative telephone number 1 of the distribution management table 202, the telephone number 10 of the telephone that has registered the voice data 301, and the distribution destination telephone. The distribution state of the telephone number 20 is not received.

  There are four types of factors that cause the distribution status of the distribution management table 202 of the registration management server 200 to be “distributed”. These can be arbitrarily changed by the distribution server 300.

  When the telephone 20 arrives as a factor 1 for setting the distribution state of the distribution management table 202 of the registration management server 200 to “distributed”, it is considered that the voice data 301 has been distributed. The distribution status of the group representative telephone number 1, the telephone number 10 of the telephone in which the voice data 301 is registered, and the telephone number 20 of the distribution destination telephone in the distribution management table 202 is “distributed”.

  When the telephone set 20 receives a call and reproduces a part of the audio data 301 as a factor 2 for setting the distribution state of the distribution management table 202 of the registration management server 200 to “distributed”, the distribution is considered as having been distributed. The server 300 indicates to the registration management server 200 the distribution status of the group representative telephone number 1 in the distribution management table 202, the telephone number 10 of the telephone in which the voice data 301 is registered, and the telephone number 20 of the distribution destination telephone. And

  As a factor 3 for setting the distribution state of the distribution management table 202 of the registration management server 200 to “distributed”, when the telephone 20 receives an incoming call and reproduces all the contents of the audio data 301, it is considered that the distribution has been performed. The server 300 indicates to the registration management server 200 the distribution status of the group representative telephone number 1 in the distribution management table 202, the telephone number 10 of the telephone in which the voice data 301 is registered, and the telephone number 20 of the distribution destination telephone. And

  As a factor 4 for setting the distribution status of the distribution management table 202 of the registration management server 200 to “distributed”, the telephone 20 receives a call and the telephone 20 transmits an arbitrary single-digit number at an arbitrary timing. In this case, the distribution server 300 determines that the distribution server 300 has registered the group representative telephone number 1 in the distribution management table 202, the telephone number 10 of the telephone in which the voice data 301 is registered, and the telephone number 20 of the distribution destination telephone. The distribution status of is “distributed”.

  The distribution server 300 in FIG. 2 confirms the distribution state of the distribution management table 202 of the registration management server 200 to the registration management server 200 at any time, and if “undelivered” exists, switches to the telephone number of the distribution destination telephone. The operation of transmitting via 100 is repeated until there is no “undelivered”. This operation is performed in parallel.

  Next, claim 2 will be described in detail with reference to the drawings.

  Taking the group management table of FIG. 3 as an example, the telephones 10, 20, and 30 of FIG. 2 belong to the group representative number 1 and belong to a specific number of telephone groups. Telephones other than the telephones 10, 20, and 30 do not belong to the group representative number 1.

  A number of specific telephones can be registered in the group representative number of the group management table of FIG.

  The switch 100 in FIG. 2 is a switch that can make and receive calls with the group representative number in the group management table in FIG.

  When the telephone 20 in FIG. 2 makes a call to the group representative number 1, the exchange 100 receives the group representative number 1 and connects the line to the distribution server 300.

  The distribution server 300 in FIG. 2 notifies the group management number 1 and the telephone number 20 of the telephone 20 to the registration management server 200.

  The registration management server 200 of FIG. 2 searches the group representative number 1 of the group management table 201 for the telephone number 20 of the telephone in the group, and notifies the distribution server 300 of the result.

  The distribution server 300 in FIG. 2 determines that the distribution server 300 and the exchange 100 are connected to a specific number of telephones when the telephone number 20 of the telephone in the group exists in the group representative number 1 of the group management table 201 from the search result. The use of the system related to voice distribution and time shift is permitted.

  The distribution server 300 of FIG. 2 disconnects the line when the telephone number 20 of the telephone in the group does not exist in the group representative number 1 of the group management table 201 based on the search result. Then, the disconnection of the line of the distribution server 300 is detected, and the same line of the exchange 100 is disconnected. In this case, the use of the system relating to voice distribution and time shift between a large number of specific telephones is not permitted.

  When the telephone number 20 of the telephone in FIG. 2 is permitted to use the system by the distribution server 300, the distribution server 300 sends the group representative telephone number 1 of the distribution management table 202 to the registration management server 200 and the telephone of the distribution destination telephone. A search process is requested to determine whether or not there is an “undelivered” item in the distribution state of number 20.

  As a result of the search performed by the registration management server 200 in FIG. 2, if there is a distribution state “undistributed”, the distribution server 300 notifies the telephone 20 that there is audio data 301. When the telephone 20 does not transmit an arbitrary number, the recorded voice data 301 is distributed. When the telephone 20 transmits an arbitrary single-digit number, the voice recording process of the voice data 301 of claim 1 is performed.

  As a result of the search by the registration management server 200 of FIG. 2, when the audio data 301 does not exist, the audio recording process of the audio data 301 of claim 1 is performed.

  There are three types of factors that cause the distribution status of the distribution management table 202 of the registration management server 200 to be “distributed”. These can be arbitrarily changed by the distribution server 300.

  When the telephone set 20 transmits to the group representative number 1 in the group management table 201 as a factor 1 for setting the distribution status in the distribution management table 202 of the registration management server 200 to “distributed”, and a part of the audio data 301 is reproduced. The distribution server 300 determines to the registration management server 200 the group representative telephone number 1 in the distribution management table 202, the telephone number 10 of the telephone in which the voice data 301 is registered, and the telephone number 20 of the distribution destination telephone. The distribution state is “distributed”.

  As a factor 2 for setting the distribution status of the distribution management table 202 of the registration management server 200 to “distributed”, the telephone 20 transmits to the group representative number 1 of the group management table 201 and reproduces all the contents of the audio data 301. In this case, the distribution server 300 determines that the distribution server 300 has registered the group representative telephone number 1 in the distribution management table 202, the telephone number 10 of the telephone in which the voice data 301 is registered, and the telephone number 20 of the distribution destination telephone. The distribution status of is “distributed”.

  As a factor 3 for setting the distribution status of the distribution management table 202 of the registration management server 200 to “distributed”, the telephone 20 transmits to the group representative number 1 of the group management table 201, and at an arbitrary timing, an arbitrary digit. When the telephone 20 makes a call, the distribution server 300 considers that the number has been distributed, and the distribution server 300 registers the group representative telephone number 1 in the distribution management table 202 and the telephone number 10 of the telephone that has registered the voice data 301 with the registration management server 200. The distribution state of the telephone number 20 of the distribution destination telephone is “distributed”.

  The telephone 20 in FIG. 2 can disconnect the line at an arbitrary timing. The exchange 100 that detects the disconnection of the line disconnects the line, and the distribution server 300 also detects the disconnection of the line and disconnects the line.

  The present invention enables smooth information distribution by providing one-to-many and non-real-time voice communication that can only realize a one-to-one voice signal having an advanced communication function. To do.

  For example, it is possible to transmit information quickly and accurately by using an emergency communication network in a company / organization that requires immediate distribution to a specific number.

It is a comparison figure of this system and other services. It is a configuration block diagram of an embodiment. This is an item of the group management table of the group management table 201 of FIG. This is an item of the distribution management table of the group management table 202 of FIG.
