[0020] Also, in the hold system disclosed in Unexamined Japanese Patent Application No. 2000-295354 (Conventional Art Example 2), every time a hold sound is provided, a media player corresponding to the hold sound must be attached and transmitted, resulting in waste
[0021] Also, in the system disclosed in Unexamined Japanese Patent Application No. 2000-270026 (Conventional Art Example 3), when handover is performed, communication terminals A and B each temporarily have two audio paths (e.g., communication Terminal A has an audio path for providing hold tone to communication terminal B and an audio path for transmitting communication terminal B's transfer request to communication terminal C via audio), which results in a heavy load on terminal audio path control and buffer control

Embodiment 1

[0065] In Embodiment 1, a switching system is described in which the hold tone used in the hold operation is generated by conversion from hold tone source data.

[0066] As shown in Figure 4, this switching system includes IP network 130, and it is made up of Internet network, LAN, IP-VPN or similar dedicated line etc.; Communication terminal 100 and 110, it is connected to IP network 130, and has telephone function ; The call control device 120 is used to perform address analysis and perform connection between the communication terminal 100 and the communication terminal 110; and switches 140, 150 and 160 are used to switch and transfer received packets so that they are transferred to correct transfer destination.

[0067] For example, communication terminals 100 and 110 may be IP phones. The communication terminal 100 on the side that performs the holding operation includes a communication section 101 that performs communication using at least a packet; a holding section 10...

Embodiment 2

[0092] In Embodiment 2, a switching system is described in which the side of the communication terminal that receives the supply of the hold tone converts the received hold data into a hold tone that can be interpreted.

[0093] As shown in FIG. 6, in this switching system, a communication terminal 200 providing a hold tone includes an additional data generation section 201 which appends hold data 103 to a hold message generated by the hold section 102 instead of the hold data conversion section. Equally, the communication terminal 210 that receives hold tone provides includes additional data analysis part 211, obtains the hold data that is added in the hold message that is analyzed by hold part 112; The hold data is converted into audio data of an audio codec supported by the communication terminal 210 . All the other structures are the same as in Example 1 (see Figure 1).

[0094] As in Embodiment 1, the hold data conversion section 212 performs audio codec conversion when ...

Embodiment 3

[0115] In Embodiment 3, a switching system is described in which a call control device has a hold data switching function.

[0116] As shown in FIG. 11, in this switching system, a call control device 310 includes a communication section 311 which at least utilizes a packet to perform communication; Interpretable codec capability in; keep data conversion part 313, which based on the information in terminal capability information database 312, will keep data converted into data of codec supported by communication terminal 300; additional data analysis and generation part 314, be used for obtaining the hold data that is attached to the received hold message, and generate the hold message that adds the audio data converted by the hold data conversion part 313; An information database 312 , a hold data conversion section 313 and a data analysis and generation section 314 . The hold data conversion section is provided only in call control device 310 and not in communication termin...

Abstract

An exchange system capable of effectively providing a hold sound during holding time. The exchange system includes a first communication terminal (100) capable of packet communication, a second communication terminal (110) performing packet communication with the first communication terminal (100), and a network (130) connecting the first communication terminal (100) to the second communication terminal (110). When the first communication terminal (100) sets the second communication terminal (110) to the hold state, the first communication terminal (100) converts its hold data (103) by hold data conversion means (104) into a speech which can be interpreted by the second communication terminal (110) and transmits the converted speech as a hold sound.

Description

technical field [0001] The present invention relates to a switching system capable of switching real-time audio calls etc. between communication terminals via the Internet, a local area network, etc., and more particularly to a method capable of placing a call on hold while the call is in progress Efficient handling of status, transfer of calls to another communication terminal, etc. Background technique [0002] In addition to using personal computers on the Internet, the popularity of IP phones capable of making calls from ordinary home phone terminals through Internet IP (Internet Protocol) networks has begun to increase rapidly. [0003] However, when an IP network is used instead of a telephone network built around a PBX installed in an office, measures must be taken to realize various telephone services previously handled by the PBX. [0004] Telephony services performed by standard PBXs include call hold and transfer services. These are common services whereby a cal...
