Description

  The present invention relates to a floor management system, a floor management method, and a program for performing floor management of other terminals in half-duplex communication.

  The PoC (Push-to-Talk over Cellular) is a means for realizing quick communication between one-to-one or between groups. For example, as shown in FIGS. 1 and 2, it is possible to use a service in which a portable terminal is used like a transceiver and a conversation button is pressed when speaking. At this time, in order to start a conversation, instead of turning the dial, you can easily access the "Buddy List" including the phone book and select the person you want to contact by simply pressing a button. . In addition, the sender's voice is delivered to the receiver by simply pressing the button again and speaking.

  A feature of PoC is that voice messages can be broadcast simultaneously to a large number of partners. Unlike conventional voice call services that are connected by a circuit switching system via a telephone exchange, it is realized by sending it through a packet communication network.

  For mobile operators, PoC opens up a whole new area of voice services and greatly enhances telephone services. End-users who have PoC capabilities on their phones have been able to use the device more frequently, as a result of past experience, which has resulted in new revenue streams for mobile operators. Offers the potential to generate high returns at a relatively low risk from existing infrastructure.

  However, in the conventional PoC communication / call, the right to speak from the own terminal is controlled by pressing the Push button, and the audio / video data only in the own terminal is mutually sent. In this method, since the right to speak can be controlled only by the audio / video data from the own terminal, the PoC participating user terminals are limited to those that can be directly manually operated by the user, such as PCs and mobile terminals. There was a problem that terminals that cannot be directly operated, such as unattended surveillance monitors, could only receive.

  As a related technique, Japanese Patent Application Laid-Open No. 2001-76273 discloses a home security system. This home security system includes a monitoring device that performs indoor and outdoor monitoring, a control device that performs monitoring control, and a communication device that performs communication control. The monitoring device includes a monitoring camera. The communication device includes a high-efficiency video encoding unit that performs high-efficiency encoding on a video captured by the monitoring camera, and a high-efficiency video encoding unit that receives an incoming call from an external communication terminal. An incoming / outgoing call control means for transmitting the efficiency-encoded moving image to the communication terminal at a low bit rate.

  Japanese Patent Laid-Open No. 2002-291057 discloses a remote control device. In this remote operation device, a home control device having a control function for centrally controlling each device in the home is connected to a communication network via a communication module having a communication function. When the communication module is accessed from an external communication means, the in-home control device determines whether the identification information and password transmitted from the communication means are those of a control authorized person registered in advance, and performs control. Permit access to the home control device only during access by the permitter.

The second effect is that, since the PoC service is used, information from other terminals can be enjoyed "to a plurality of participants at the same time" when the user "want to see / obtain" information.

Hereinafter, a first embodiment of the present invention will be described with reference to the accompanying drawings.
As shown in FIG. 3, the present invention relates to a floor management system that supports PoC (Push-to-Talk over Cellular) communication / call. The floor management system of the present invention includes a PoC terminal 1, a PoC server 2, and an authentication server 3.

The PoC terminal 1 (1-i, i = 1 to n: n is the number of PoC terminals) is a terminal (including network equipment) that supports PoC communication / call, and if registered in advance, You can control the right to speak.
The PoC server 2 is responsible for PoC session establishment / speaking right management in the PoC terminal 1. Note that a SIP (Session Initiation Protocol) server may be used as the PoC server 2.
The authentication server 3 authenticates a user who has registered in advance when controlling the speaking right of another terminal during the PoC session. When registering, the data is written in the database from the PoC terminal 1 by Web registration or the like, or the maintenance / administrator of the authentication server 3 directly writes in the database.

  For data registered in the authentication server 3, information that can identify the PoC terminal 1 at the time of PoC communication / call is used. For example, when the PoC terminal 1 is a mobile phone, identification information unique to the PoC terminal 1 such as a telephone number or mail address of the PoC terminal 1 or a terminal ID (Identification) given to the PoC terminal 1 is registered. .

  The PoC terminal 1 and the PoC server 2 are connected via a network (communication line) 4. A transmission path for transmitting and receiving data among the PoC terminal 1, the PoC server 2, and the authentication server 3 may be wired or wireless. The authentication server 3 may be provided between the PoC terminal 1 and the PoC server 2.

As an embodiment of the present invention, control of a monitor using PoC will be described.
Referring to FIG. 4, a PoC system as an embodiment of the present invention is shown. In the figure, user terminal A: 1-1, user terminal B: 1-2, and terminal C: 1-3 corresponding to PoC terminal 1 exist. User terminal A: 1-1 and user terminal B: 1-2 are in a state where the user can directly manually. As the user terminal A: 1-1 and user terminal B: 1-2, a portable terminal and a PC terminal are assumed here. Terminal C: 1-3 is a terminal that cannot be directly manually operated, such as an unattended monitoring monitor. This is connected to the network 4 for automatic operation and cannot be directly operated by the user. In the PoC server 2, the user terminal A: 1-1, the user terminal B: 1-2, and the terminal C: 1-3 are connected to each other via the network 4, and in the case of PoC service, call establishment / PoC group creation / Management / Transfer of voice data / Controls the right to speak. The authentication server 3 authenticates whether or not use is permitted when controlling the right to speak of another terminal during a PoC call.

  The PoC server 2 manages the right to speak and grants the right to speak in the order of arrival. Usually, the right to speak is not given to a plurality of terminals at the same time. For example, when the user terminal A: 1-1 wants to acquire the right to speak, the user terminal A: 1-1 sends the packet data of the right to speak to the PoC server 2 by pressing the Push button. If no terminal holds the right to speak at the time of the request, a permission notice is sent from the PoC server 2 to the user terminal A-1-1 to allow data such as audio and video from the user terminal A-1-1, Copy and transfer to each terminal.

  When the right to speak is released from the terminal, the right to speak is newly granted on a first-come-first-served basis. At this time, the addresses and the like of each group member using the terminal are registered in the PoC server 2 when the PoC session is established.

Next, the operation of the present invention will be described with reference to FIG.
(1) Step S101
First, the user A who operates the user terminal A: 1-1 creates a call (communication) group using the user terminal A: 1-1, or selects a party with whom PoC communication / call is desired, and accesses the PoC server 2. Then, the PoC session between the user terminal A: 1-1 and the corresponding partner is established.
(2) Step S102
Next, the user A designates the other terminal C: 1-3 previously registered in the authentication server 3 from the user terminal A: 1-1, and the right of use is authenticated by the authentication server 3.
(3) Step S103
Next, the user A selects, from the user terminal A: 1-1, data (stored file / streaming video / audio, etc.) in the terminal C: 1-3 for which Push distribution is desired.
(4) Step S104
Next, the user A presses the Push button of the user terminal A-1-1 to make a request for granting the speaking right of the terminal C: 1-3.
(5) Step S105
Then, the floor is granted to the terminal C: 1-3 by the floor management function of the PoC server 2.
(6) Step S106
Terminal C: 1-3 may, with the application of floor, the user terminal A: Push to distribute the set data (storage file / streaming video, etc.) to the PoC server 2 by 1-1.
(7) Step S107
P oC server 2, Push delivered terminal C: to replicate the 1-3 of the data, and transfers it to the PoC group participant.
(8) Step S108
Finally, when the user A releases the Push button of the user terminal A-1-1, the right to speak of the terminal C: 1-3 is released (released), and the message / data Push distribution from the terminal C: 1-3 Ends.

The authentication server 3 may determine whether or not the user terminal A: 1-1 is allowed when the user terminal A- 1-1 makes a request for granting the right to speak the terminal C: 1-3. good. For example, if the user terminal A: 1-1 is registered in advance, the request for granting the right to speak is permitted. At this time, it is possible to register the PoC terminals 1 in groups, and permit only when the user terminals A: 1-1 and C: 1-3 belong to the same group. Further, the group is determined by giving the same group ID to the user terminals A: 1-1 and C: 1-3 so that the authentication server 3 checks the group ID of each terminal during PoC communication. You may carry out.
In addition, when the request for granting the right to speak of the user terminal A: 1-1 is rejected, it is possible to prevent the user terminal A: 1-1 from displaying information regarding the terminal C: 1-3.

  In the floor management system of the present invention, only when the user A presses the Push button of the user terminal A-1-1 managing the floor, other group members using other terminals can view data. . Note that the communication itself is PoC communication, and within the same Call (communication group), it is possible to transmit and receive voice / character / video transmitted from a terminal that manages the right to speak. Also, the right holder who is pressing the Push button on the terminal can also operate data transmission from another terminal.

  Note that the operation of the floor control system of the present invention may be performed by a computer executing a program. In this case, the PoC terminal 1, the PoC server 2, and the authentication server 3 are computers, each having a control unit for executing a program and a storage unit for storing the program.

  When a user registers a user for a network terminal that cannot be directly manually operated, such as a monitoring monitor, the right to speak of the network terminal can be controlled during PoC communication. In other words, this allows audio / video data to be sent from different terminals with one PC / mobile terminal.

  As described above, the feature of the present invention is that, in a call / communication in a half-duplex communication / call system (PoC call / communication), distribution of various data such as audio / video from other terminals is performed with the push button of the own terminal. This is what we made possible. When the user registered in advance controls the right to speak from another terminal, data in a network connection terminal such as a monitor can be distributed as PoC communication / call.
