Description

  The present invention relates to a system and method for updating music on hold of an IP terminal connected to an IP-PBX (Internet Protocol-Private Branch eXchange) via an IP (Internet Protocol) network.

  In recent years, for example, IP telephones and PCs connected to a LAN in each of a plurality of sites in a company are connected via an IP network, and further, voice data can be transmitted using this communication network. -Communication systems using PBX are attracting attention. In this communication system, the voice network in the system can be integrated with the data network by IP-PBX. For this reason, in an office where a system is constructed with a conventional telephone line PBX (private branch exchange), the system requires two lines of wiring: telephone wiring and data wiring. IP-PBX In the office where the system is constructed by the above, the wiring in the system is concentrated only on the data wiring, and the telephone wiring becomes unnecessary. As a result, companies that have introduced IP-PBX can not only reduce the system construction cost compared to the conventional system, but also can greatly reduce the communication cost and facilitate the maintenance of the communication system. Can do.

  In addition to these advantages, considering the current situation in which the number of companies that introduce IP telephones is rapidly increasing with the introduction of IP and broadband in the company network, PBX for telephone lines will be used in most companies in the future. It is expected to replace IP-PBX.

  In a system with such a promising IP-PBX introduced, as a method for outputting a hold tone from a busy IP phone to the other party, for example, a predetermined hold tone is held in advance in a storage area built in the IP phone. A method for reproducing this is known. In addition, as a method of updating the hold tone held for each IP telephone in this way, the control device notifies the hold tone update server of the hold tone update instruction, and in response to this notification, desired hold tone data Has been disclosed by broadcasting from a hold sound holding server to an IP phone, thereby updating the hold sound of an IP phone connected to a network (see, for example, Patent Document 1).

JP 2005-65071 A

  However, such a conventional update method always requires a dedicated music on hold server on the IP network.

  As described above, in view of the future of a system in which IP-PBX is introduced, IP telephone users, system introducers, and operators will use a simple system that does not require a music on hold server. If it is desired to update only the hold sound of a specific IP telephone to a favorite voice, it is considered that the number increases. That is, it is considered that the system introduction side may want to use, for example, a commercial (CM) or image song of a company that has introduced IP-PBX only for a holding tone of a specific IP telephone. In addition, it is considered that the user of the IP telephone may desire to customize only the music on hold of his / her IP telephone to his / her favorite music, for example, like a ringtone of a mobile phone.

  In response to such people's needs, the present invention provides a new and improved music on hold update system and method capable of easily updating the music on hold of a specific IP terminal connected to an IP network. The

  That is, in order to solve the above-described problem, according to an aspect of the present invention, an information processing device that stores one or more music on hold data, a plurality of IP terminals, and an IP-PBX The IP-PBX receives the IP terminal identification information and the music on hold data identification information, and receives the IP terminal identification information and the music on hold data identification information. Among them, the IP terminal identified from the IP terminal identification information is notified of the update request for the music on hold data identification information and the music on hold data, and the specific IP terminal notified of the update request is the information processing device. Is provided. The hold tone update system is provided that updates the hold tone by taking in the hold tone data specified from the hold tone data identification information.

  According to this, the IP-PBX notifies the update request for the music on hold data only to the IP terminal specified from the IP terminal identification information among the plurality of IP terminals connected to the IP network. Upon receiving this, the specific IP terminal takes in the hold sound data corresponding to the hold sound data identification information from the information processing device.

  According to such an update method, since the TFTP protocol is a general-purpose protocol, if there is an information processing device (for example, a PC) having the application, a dedicated hold tone is used as in the conventional hold tone data update process. The update process of the music-on-hold data can be executed without requiring a server. That is, according to the music on hold update system, if an information processing device (for example, a PC) having the TFTP protocol is connected to the IP network only when the music on hold is updated, a dedicated music on hold server is always on the IP network. Without placing a specific IP terminal, a specific IP terminal can acquire desired music on hold data from a PC having the TFTP protocol in response to a request for updating the music on hold data. Further, according to the music on hold update system, only the music on hold of a specific IP terminal among a plurality of IP terminals connected to the IP network can be updated to a desired voice. As a result, for example, even when one IP-PBX is shared by a plurality of companies, a unique hold sound can be registered for each company.

  At this time, there are a plurality of IP terminals specified from the IP terminal identification information, which are constructed at different bases, for example, a LAN (Local Area Network) or an IP-VPN (Internet Protocol) connected via an IP network. -Virtual Private Network: Each network may belong to a remote network via a virtual private communication network established via a wide area IP communication network owned by a communication carrier.

  Further, the plurality of identified IP terminals may fetch the hold tone data specified by the hold tone data identification information from the same information processing device that stores the one or more hold tone data. Good.

  In order to solve the above problem, according to another aspect of the present invention, connected to a plurality of IP terminals and an information processing device that stores one or more music on hold data via an IP network. IP-PBX, which receives IP terminal identification information and music on hold data identification information, and among music on hold data stored in the information processing device, music on hold data specified from the music on hold data identification information, An IP-PBX is provided that is controlled by the IP terminal specified from the IP terminal identification information to be updated among the plurality of IP terminals to update the hold sound of the specified IP terminal.

  According to this, the IP-PBX notifies the update request for the music on hold data only to the IP terminal identified from the IP terminal identification information among the plurality of IP terminals connected to the IP network, The specific IP terminal that has received the request causes the hold information corresponding to the hold tone data identification information to be captured from the information processing device. According to such IP-PBX control, if there is an information processing device (for example, a PC) having an application of the TFTP protocol, which is a general-purpose protocol, a dedicated on-hold tone as in a conventional on-hold tone data update process is provided. The holding tone data of the IP terminal can be updated without requiring a server. That is, according to the music on hold update system, if a PC having the TFTP protocol is connected to the IP network only when the music on hold is updated, the hold is always performed without placing a dedicated music on hold server on the IP network. In response to the sound data update request, a specific IP terminal can obtain desired hold tone data from a PC having the TFTP protocol. Further, according to the music on hold update system, only the music on hold of a specific IP terminal among a plurality of IP terminals connected to the IP network can be updated to a desired voice.

  The IP-PBX notifies the specific IP terminal of the acquisition request for the specific music on hold data to cause the information processing device to request acquisition of the specific music on hold data from the specific IP terminal. In response to this request, the information processing device may transmit the specific music on hold data to the specific IP terminal so that only the music on hold held in the specific IP terminal is updated. .

  According to this, since the specific IP terminal requests the information processing device to acquire the specific music on hold data, each IP terminal can control the timing of transmitting the request. That is, each IP terminal can start to acquire music on hold data at a timing at which the processing load is distributed based on the processing load at that time. As a result, it is possible to avoid the occurrence of packet collision as much as possible when transmitting a packet of music on hold data. As a result, by minimizing packet retransmission and packet discard, it is possible to update only the hold sound of a specific IP terminal to a desired voice while improving communication efficiency.

  At this time, the IP-PBX may be controlled to update only the on-hold tone held in the specified single IP terminal based on the IP terminal identification information designating only the single IP terminal. Alternatively, based on the IP terminal identification information designating a plurality of IP terminals, control may be performed so that only the holdings respectively held by the plurality of identified IP terminals are updated.

  According to this, it is possible to specify one IP terminal and update only the hold sound of the IP terminal. It is also possible to specify a plurality of IP terminal groups and update only the hold sound of the IP terminal group.

  The plurality of identified IP terminals may be constructed at different bases and belong to bases (remote places) via a LAN or IP-VPN connected via an IP network.

  According to this, for example, an IP terminal (in FIG. 7) belonging to a base (remote location) via a LAN or IP-VPN constructed in different bases in the company (A base and B base in FIG. 7). , IP terminals a1 and b1) can update their holding sounds. Thereby, it is possible to remotely update the hold sound of a specific IP terminal connected to the IP network using the IP-PBX.

  Further, the plurality of identified IP terminals may fetch the hold tone data specified by the hold tone data identification information from the same information processing device that stores the one or more hold tone data. Good.

  According to this, it is not necessary to provide a dedicated server for storing the music on hold data for each different base in the company. Thereby, not only the cost at the time of IP-PBX system introduction can be reduced, but also the maintenance of the communication system can be facilitated.

  Moreover, in order to solve the said subject, according to another viewpoint of this invention, it connected to IP-PBX and the information processing apparatus which memorize | stores one or more music on hold data via IP network An IP terminal that receives the notification of the hold sound data identification information and the update request for the hold sound data from the IP-PBX, thereby, among the hold sound data stored in the information processing device, the hold sound data identification information An IP terminal is provided that acquires the hold sound data specified from the above and stores the acquired hold sound data in a storage unit to update the hold sound.

  According to this, the specific IP terminal requests the information processing device to acquire the specific music on hold data, triggered by a request for updating the music on hold data from the IP-PBX. Thus, if there is a PC having an application of the TFTP protocol, which is a general-purpose protocol, the music on hold data of the IP terminal is updated without requiring a dedicated music on hold server as in the conventional music on hold data update processing. be able to. That is, according to the music on hold update system, if a PC having the TFTP protocol is connected to the IP network only when the music on hold is updated, the hold is always performed without placing a dedicated music on hold server on the IP network. In response to the sound data update request, a specific IP terminal can obtain desired hold tone data from a PC having the TFTP protocol.

  In addition, the IP terminal that has received the request can control the timing at which the music on hold data is acquired in response to the request. In other words, the IP terminal that has received the request can start acquiring the hold tone data at the timing at which the processing load is distributed based on the processing load at that time. As a result, it is possible to avoid the occurrence of packet collision as much as possible when transmitting a packet of music on hold data. As a result, by minimizing packet retransmission and packet discard, it is possible to update only the hold sound of a specific IP terminal to a desired voice while improving communication efficiency.

  At this time, there are a plurality of the information processing devices connected to the IP network, and the specific IP terminal performs information processing in addition to the music on hold data identification information and the update request for the music on hold data from the IP-PBX. By receiving the device identification information, the specific hold sound data is acquired from the information processing device specified from the information processing device identification information, and the acquired hold sound data is stored in the storage unit to update the hold sound You may make it do.

  According to this, it is possible to specify a specific information processing device among a plurality of information processing devices connected to the IP network, and obtain desired hold sound data from the specific information processing device.

  In order to solve the above-described problem, according to another aspect of the present invention, an information processing device that stores one or more music on hold data, a plurality of IP terminals, and an IP-PBX are connected to an IP network. The IP-PBX receives the IP terminal identification information and the music-on-hold data identification information, and receives the IP terminal identification information and the music on hold data identification information. Among the IP terminals identified by the IP terminal identification information, the update request for the music on hold data identification information and the music on hold data is notified, and the specific IP terminal notified of the update request The holding tone update method for updating the holding tone by taking in the holding tone data specified by the holding tone data identification information from among the holding tone data stored in the information is provided.

  According to this, the IP-PBX notifies the update request for the music on hold data only to the IP terminal specified from the IP terminal identification information among the plurality of IP terminals connected to the IP network. Upon receiving this, the specific IP terminal takes in the hold sound data corresponding to the hold sound data identification information from the information processing device. As a result, if there is an information processing device (for example, a PC) having an application of the TFTP protocol, which is a general-purpose protocol, an IP terminal can be used without requiring a dedicated music on hold server as in the conventional music on hold data update processing. The music on hold data can be updated. That is, according to the music on hold update system, if a PC having the TFTP protocol is connected to the IP network only when the music on hold is updated, the hold is always performed without placing a dedicated music on hold server on the IP network.
