摘要： PROBLEM TO BE SOLVED: To obtain a voice communication system succeeding header information of a voice packet outputted from a repeater to a packet terminal even when the repeater is switched during communication. SOLUTION: A non-packet terminal 1 and a repeater 20 generates the same value as packet header information when starting a voice communication. The non-packet terminal 1 updates the packet header information according to the same rule as a packet assembly portion of the repeater 20 during the voice communication. When switching of the repeater 20 occurs, the updated packet header information is transmitted from the non-packet terminal 1 to a repeater 21 after switching. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To obtain a call control server and a communication system which are highly reliable and continue call connection even if a call control server fails, without requiring a memory device for storing a call control log temporarily, thus lowering the possibility of system stop.SOLUTION: During normal operation, second terminal information of a second IP terminal controlled by other call control server is transferred therefrom, and when failure occurs in communication between other call control server and the second IP terminal, for example, telephone number of a destination, i.e., a first IP terminal, is received from the second IP terminal, and address information corresponding to the telephone number of the first IP terminal, transmitted therefrom and stored, is searched and transmitted to the second IP terminal. Consequently, an external memory device is not required, and communication between first and second IP terminals is enabled even if fault occurs in other call control server.

摘要： PROBLEM TO BE SOLVED: To solve the problem that transfer efficiency is improved in header compression, code conversion, etc. in communication on a transmission line with a limited transmission band, while, when a new call is connected and used while a plurality of calls are communicated, if a full-header packet is delivered, packets of the other calls are discarded or delayed. SOLUTION: Information acquired by an SIP packet monitor is omitted from a packet header for transmission, and then packet type information by both internal coding method and external coding method is added to create a short header. Coded voice data obtained by coding the voice data of the packet for transmission and the short header are assembled into a packet and are delivered to a device at the other end. Then, based on the packet information contained in a packet received from the device at the other end, the speech data code-converted by a reception-side code converting means and a packet header which is the short header in the received packet decoded by a packet header decoding means based on the information from the SIP packet monitor are assembled into a packet and are delivered to a telephone device.

摘要： PROBLEM TO BE SOLVED: To provide a voice transmission device capable of realizing a clock difference absorbing function with higher voice quality and high precision at a low cost, which can absorb a difference of clock signals between a transmitter side device and a receiver side device. SOLUTION: A buffer control section 15 inserts a silence voice signal generated by a silence coding voice signal generating section 13 to a voice signal stored in a buffer section 14 on the basis of a storage amount of voice signals monitored by a buffer capacity monitor section 16 and voiced/silence information detected by a voice detection section 11 or aborts the silence voice signal from the voice signals stored in the buffer section 14. Thus, a change in the storage capacity of the voice signals stored in the buffer section 14 is reduced so as to eliminate defects in voice transmission due to a difference of clock signals between the transmitter side device and the receiver side device.

摘要： PROBLEM TO BE SOLVED: To obtain a voice data transmission system capable of suppressing an increase in transmission delay corresponding to opposite party communication devices.
SOLUTION: A data transmission section 104 stores voice data and identification data of an own device in a transmission frame for transmitting to a radio communication line. A data reception section 105 receives the transmission frame via the radio communication line, and notifies the data transmission section 104 of a data retransmission request in detection of the error. An identification data reception section 110 extracts identification information of the opposite party communication device as response data to the identification data of the own device from the transmission frame received by the data reception section 105. A voice communication setting section 111 sets whether the data retransmission request is stopped for the data reception section 105, based on the identification information of the opposite party communication device extracted by the identification data reception section 110.
