Description

  The present invention relates to a radiotelephone terminal device suitable for application to a mobile phone terminal device using a service called PoC (Push-to-Talk over Cellular), for example, and a data distribution method using the terminal device.

  One of the services performed using a wireless telephone terminal device is called PoC. This service is a technology that uses a radio telephone terminal device like a transceiver, and enables 1-to-N group communication.

  There are several PoC implementation methods, but the basic mechanism is the same, and includes a PoC server having a session management function and a floor control function, and a GLMS (Group and List Management Server) for managing a group list. Then, the terminal device that wants to perform this service connects to these servers via a wireless telephone line, and the terminal device that has obtained the right to speak from the server side sends voice data to the server. The server performs a process of delivering the transmitted audio data to other connected terminal devices in almost real time. In the following description, when a PoC server is described, it is assumed that all functions necessary for the operation of a PoC service such as GLMS are provided, and these servers will be described without particular distinction.

  In the PoC service, when the right to speak is obtained by operating the terminal device once, the time during which the voice data can be transmitted from the terminal device that obtains the right is limited to a predetermined time determined by the system such as 30 seconds. When the transmission of the voice data from the terminal device that has obtained the right to speak is completed or 30 seconds have elapsed, any terminal device is in a free state in which the right to speak can be acquired. In a free state, a new speaking right is given to the terminal device that has performed an operation (push operation) for acquiring the speaking right earliest. As can be seen from the above description, in the case of the PoC service, one-way voice transmission like a transceiver is performed alternately within a group, and two-way communication is not possible.

Japanese Patent Laid-Open No. 2004-228561 describes a summary of PoC service.
JP 2005-234666 A

  By using the PoC service described above, voice can be transmitted alternately between a plurality of terminal devices connected to the server at the same time, which is convenient when a conversation is made in a group. For voice data transmission, only voice data packets are sent alternately through the server, and the amount of data to be transmitted is smaller than in the case of simultaneous calls between many people, and communication resources are reduced. Since communication resources can be effectively utilized and communication resources can be effectively utilized in this way, communication charges (call charges) have the advantage of being able to provide services at a relatively low cost compared to ordinary voice calls.

  However, the conventionally proposed PoC service is only a service for transmitting voice data, and it has been required to use the PoC service to enable a more advanced service.

  The present invention has been made in view of such a point, and an object thereof is to enable more advanced data distribution between groups using a voice group transmission system such as a PoC service.

  In the present invention, two or more wireless telephone terminal devices are connected to a predetermined server at the same time via a wireless telephone line. One wireless telephone terminal device that has the right to speak while enabling voice data transmitted from one wireless telephone terminal device to the server to be transmitted to other wireless telephone terminal devices in almost real time. Therefore, instead of voice data, the music data stored in the terminal device is transmitted to the server, and the music data transmitted to the server is transmitted to other wireless telephone terminal devices in almost real time. Is.

  By doing so, it is possible to distribute the music data stored in one wireless telephone terminal device almost simultaneously to all the wireless telephone terminal devices between the connected groups by using the voice group distribution function. become.

  According to the present invention, music data stored in one wireless telephone terminal device can be distributed almost simultaneously to all the wireless telephone terminal devices between the connected groups. For example, wireless data possessed by one person in the group The recommended music in the music data stored in the telephone terminal device can be distributed to the terminal devices of other members in the group for listening, and music recommendations can be easily made in the group.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. In this example, the system configuration uses a radiotelephone terminal device configured as a mobile phone terminal. FIG. 1 is a diagram showing a configuration example of the entire system. The system configuration of this example will be described with reference to FIG. 1. Here, a state in which a plurality of mobile phone terminal devices 100a, 100b, 100c, and 100d are connected to the radio telephone network 11 by radio communication is shown. The radio telephone network 11 includes a base station that performs radio communication with a mobile phone terminal device, a communication network that connects the base stations, and the like. A PoC (Push-to-Talk over Cellular) server 12 is connected to the wireless telephone network 11 of this example, and a terminal device that performs a PoC service accesses this server. In the following description, the four mobile phone terminal devices 100a to 100d shown in FIG. 1 are shown as one group that executes the PoC service. One group that executes the PoC service can be configured with at least two mobile phone terminal apparatuses, and the maximum number of one group is defined by the system.

  Each of the mobile phone terminal devices 100a to 100d is configured as a terminal device that performs a voice call, and a specific configuration thereof will be described later. As one of operation means provided in the operation unit, a push button for PoC communication is provided. 106a is prepared.

  When executing the PoC service, for example, a single mobile phone terminal device 100a is connected to the PoC server 12 so as to be able to transfer data. The telephone terminal devices 100b, 100c, and 100d are also connected to the PoC server 12 to enable data transfer. In that way, a group is formed by the mobile phone terminal devices 100a to 100d connected to the PoC server 12, and for example, the terminal device in which the push button 106a is first pressed while the speaking right is free secures the right to speak, While the push button 106a is kept pressed, the voice data picked up by the microphone of the terminal device is sent to the PoC server 12 as predetermined packet data.

  The PoC server 12 immediately distributes the received packet data to the other mobile phone terminal devices 100b to 100d in the group, and the mobile phone terminal devices 100b to 100d that have received the packet data include the packet data in the packet data simultaneously with reception. The audio data is demodulated and output (reproduced). By performing the processing in this manner, the voice data transmitted by the mobile phone terminal device 100a is output from the other mobile phone terminal devices 100b to 100d in the group in almost real time, and into the voice group. Can be delivered simultaneously.

  When one mobile phone terminal device returns from the state in which the push button 106a is pressed to the original state, the mobile phone terminal device has no right to speak, and the right to speak becomes free in the group. Any of the mobile phone terminal devices can acquire the right to speak. Further, the maximum time during which a voice can be transmitted while securing the right to speak is limited to a fixed time. For example, when the time is limited to 30 seconds and 30 seconds have passed, the right to speak is lost even if the push button 106a is kept pressed, and the right to speak becomes free in the group.

  Up to this point, the processing and configuration already known for executing the PoC service have been described. In this example, the PoC service is used to enable simultaneous distribution of not only voice but also music data to a group. Specific processing necessary for distribution of music data will be described later.

  Next, the configuration of the mobile phone terminal device used in the system of this example will be described with reference to FIG. The mobile phone terminal device 100 shown in FIG. 2 has a configuration common to the mobile phone terminal devices 100a to 100d shown in FIG. An antenna 101 that performs wireless communication with a base station is connected to a communication circuit 102. The communication circuit 102 is communication processing means for performing reception processing and transmission processing such as demodulation of a received signal and modulation of a signal to be transmitted. The audio data in the received data packet is supplied to the speaker 104 as an analog audio signal and output. Also, the audio signal picked up by the microphone 103 is supplied to the communication circuit 102 to be used as audio data for transmission, and the audio data is converted into a transmission data packet and transmitted to the base station side. Data transmission between the communication circuit 102 and each unit is performed using a data line 160.

  Further, the communication circuit 102 is configured to perform data transfer with the control unit 120 via the control line 150, and reception and transmission are performed based on an instruction from the control unit 120. In addition, received data other than audio data is sent to the control unit 120 and stored in the memory 105 as necessary. Data that needs to be transmitted is also sent from the control unit 120 or the memory 105 to the communication circuit 102 for transmission processing. When transmitting music data to be described later, the music data stored in the memory 105 (or an external storage device 122 to be described later) is sent to the communication circuit 102 and wirelessly transmitted.

  Further, the operation data of the operation unit 106 constituted by operation means such as operation keys arranged in the cellular phone terminal device 100 is supplied to the control unit 120, and the display unit constituted by display means such as a liquid crystal display panel. The display at 107 is also executed under the control of the control unit 120. The operation means arranged as the operation unit 106 includes the push button 106a shown in FIG.

  The mobile phone terminal device 100 of this example also has a function as a music playback device that stores and plays back music data. In order to function as this music playback device, a music data control unit 123 is provided, and is stored in the built-in memory 105 or the external storage device 122 connected to the external device connection unit 121 under the control of the music data control unit 123. The music data can be output from the music speaker 124 as an analog audio signal. As the external storage device 122, for example, storage (recording) means such as a memory card is used.

  As the storage of music data in the memory 105 or the external storage device 122, for example, music data downloaded from a server that accesses music data distributed by wireless communication using the communication circuit 102 is assumed. Is done.

  In the configuration shown in FIG. 2, a remote control device 200 is connected to the mobile phone terminal device 100, and music playback can be controlled by the remote control device 200, and music can be output. That is, as shown in FIG. 2, the connection terminal 201 of the remote control device 200 is connected to the remote controller connection terminal 130, and music playback on the terminal device 100 side is controlled by the remote controller control unit 204. Control is possible. The remote control device 200 includes an external operation unit 205, and an operation based on the operation of the operation unit 205 is performed. Further, the remote control device 200 includes an external microphone 202 and an external earphone 203 so that music can be played back and input / output of voice for a call by the remote control device 200. For data transfer between the mobile phone terminal device 100 and the remote control device 200, for example, wireless transmission such as Bluetooth (trademark) may be applied. Further, the external storage device 122 shown in FIG.

  Note that the cellular phone terminal device 100 of this example performs PoC communication, and a predetermined key operation constituting the operation unit 106 is performed in a state where the push button 106a shown in FIG. If there is, the music data stored in the memory 105 or the external storage device 122 is transmitted to the connected server side under the control of the music data control unit 123 without sending audio data. . At the time of transmitting the music data, if the memory 105 or the like stores data associated with the music data such as a song title or a player name, the associated data may be transmitted.

  Next, a processing example in each mobile phone terminal device when the PoC service is executed with the configuration shown in FIG. 1 using a plurality of mobile phone terminal devices 100 having the configuration shown in FIG. This will be described with reference to a flowchart. First, in order to start PoC communication with a mobile phone terminal device, the PoC server is accessed and registration work is performed (step S11), and the process waits until a terminal device as a connection destination is registered (step S12). . When each terminal device constituting the group is registered in the server, a session can be invited to another mobile phone terminal device via the PoC server, and a response corresponding to communication is received from the mobile phone terminal device that has received the invitation. As a result, a session is started (step S13).

  When the session is started, it is determined whether or not the session is ended (step S14). When it is determined that the session is ended, an end process is performed (step S15). If it is determined that the session is continuing, it is determined whether the right to speak is free as the current state (step S16). If the floor is not free, audio data or music data transmitted from another terminal device in the group via the server is received and output (step S17), and output processing with one floor is performed. When finished, the process returns to the determination in step S16 as to whether or not the right to speak is free.

  If it is determined in step S16 that the right to speak is free, it is determined whether the right to speak is obtained based on the operation of the push button 106a of the terminal device (step S16). S18). If the floor is not acquired, the process returns to the determination in step S16 as to whether or not the floor is free.

  When acquiring the right to speak in step S18, it is determined whether the data sent to the server with the acquired right to speak is audio data or music data (step S19). In the case of this example, when the push button 106a is only pressed, the process proceeds to step S20 to perform processing for sending audio data. After the push button 106a is pressed, another operation is performed. If there is, the process moves to step S21 to perform processing for sending music data.

  When performing the process of sending the voice data in step S20, the voice data is distributed to other mobile phone terminals in the group via the server with a predetermined time (for example, 30 seconds) as the maximum time. When the delivery of one unit is completed, the right to speak is released, and the process returns to step S14.

  When performing the process of sending music data in step S21, the user is caused to perform an operation of selecting music data, and the music data selected by the operation is sent to another mobile phone in the group via the server. Deliver to the terminal device. At this time, for example, music data for one song is distributed. Alternatively, the music data is distributed for a predetermined time. Then, it is determined whether or not the distribution of music data has been completed (step S22). If it is determined that the distribution has ended, the right to speak is released in step S20, and the process returns to step S14.

  Next, an example of a communication state between the two mobile phone terminal devices 100a and 100b and the PoC server will be described with reference to the connection sequence diagram of FIG. When a group is composed of three or more devices, the number of terminal devices that perform the same processing as the mobile phone terminal device 100b increases. In FIG. 4, registration processing A, session start B, floor acquisition C, and distribution start D are shown separately. First, the registration process A will be described. It is assumed that there is registration (registration) from the mobile phone terminal device 100a to the PoC server (step S31), and there is registration from the other mobile phone terminal device 100b to the PoC server (step S33). For each registration, a message for accepting the registration is returned (steps S32 and S34).

  As a session start B, when there is a connection request (invite) from the mobile phone terminal device 100a to the PoC server (step S35), the connection request is transmitted to another mobile phone terminal device 100b (step S36). The consent from the device 100b is transmitted to the mobile phone terminal device 100a via the mobile phone terminal device 100b (steps S37 and S38).

  For example, when the floor is free, for example, when a floor request is sent from the mobile phone terminal device 100a to the PoC server (step S39), the floor C is granted. Is returned (step S40), the right to speak is acquired, and the voice data or music data can be transmitted.

  The distribution start D after acquiring the right to speak is an example of performing music distribution here, and the music data is sent from the mobile phone terminal device 100a that has acquired the right to speak to the PoC server (step S41). A process of immediately distributing the music data from the PoC server to all other terminal devices in the group is performed (step S42). When music data is transmitted to the PoC server, if accompanying data such as a song title is also transmitted, the accompanying data is also distributed to each terminal device.

  The terminal device that has received the distribution outputs (reproduces) music from the music reproduction speaker 124 (FIG. 2) included in the terminal device. Alternatively, it is output from the external earphone 203 on the remote control device 200 side shown in FIG. At this time, the music data received from the PoC server may be restricted so that it cannot be stored in the internal memory 105 or the external storage device 122, and copyright protection or the like may be performed. Alternatively, storage in the external storage device 122 may be limited so that only the built-in memory 105 can be stored. Even when the internal memory 105 or the external storage device 122 can be stored, the number of times that the music data can be reproduced may be limited.

  In the flowchart of FIG. 3, it is assumed that the music data is distributed for a relatively long time such as one song, but the distribution of the music data is the same as that of the audio data. The maximum distribution time may be set to prevent the right to speak from being monopolized for a long time. That is, for example, as shown in the flowchart of FIG. 5, after starting the distribution of the music data in step S21, it is determined whether the distribution of the music data is completed (step S22), and not determined to be completed. If so, it is determined whether or not a certain period of time has elapsed since the start of distribution (step S23). If it is determined that a predetermined period of time (eg, 1 minute) has not elapsed, step S22 is performed. If it is determined that a certain time has elapsed, the right to speak is released in step S20, and the process returns to step S14. In FIG. 5, the other processes are the same as those in the flowchart of FIG.

  By restricting in this way, it is possible to prevent a terminal device that distributes music from monopolizing the right to speak for a long time. When the music data distribution time is limited, the time is longer than the maximum time for audio data distribution (for example, 30 seconds for audio distribution is set to about 1 to several minutes for music distribution). May be set so that music of a reasonable length is played.

  Alternatively, after distribution of the audio data is started, the distribution of the music data is continued, and the state in which the music is played on each terminal device is continued, so that other terminal devices can acquire the right to speak, When the acquisition is performed, the music distribution may be stopped and the processing for transferring the right to speak to the requested terminal device may be performed.

  Further, when distributing music data via a PoC server, when accompanying data such as a song name, a player name, and an album name is stored in the transmission source terminal device, The accompanying data may also be distributed simultaneously via the PoC server. Thus, when accompanying data such as a song name is distributed, the song name or the like may be displayed on the display unit 107 of the terminal device based on the accompanying data.

  Alternatively, the accompanying data such as the song name received by the terminal device is stored in the memory 105 in the terminal device on the receiving side, and the stored song name data is used for one song of the corresponding song. It may be used when purchasing music data. In other words, if a user likes a song that has been distributed and listened to via a PoC server on a mobile phone terminal device, he / she accesses a website on the Internet that provides a music data sales service (download service). Then, the song name data stored in the terminal device may be used to search for the corresponding song, and the found song may be downloaded.

  In the above-described embodiment, an example in which a mobile phone terminal device is used to perform distribution in a system called a PoC service has been described. However, one audio data distribution through another similar server is performed. Of course, the present invention can also be applied to a system for performing a plurality of wireless communication terminal apparatuses.
