Abstract: When half-duplex many-to-many communication is performed among a plurality of mobile stations having different codecs in a single group, transcoding is performed with a small number of codec circuits. A transcoder manages an SSRC of a received RTP packet, detaches voice information from a jitter buffer, which is identical to a latest SSRC, and inputs the detached voice information to a codec circuit. As the latest SSRC is switched, a voice sending station subject to transcode is switched, and mobile stations using the same codec share the codec circuit. Therefore, in a half-duplex many-to-many communication (group communication) system, called a professional mobile radio system, push-talk, or press-talk, it is not necessary to switch the transcoder until a radio station which takes a talk burst is changed during a single call (call session).

Abstract: There is provided a communication system in which semi-duplex many-to-many multicasting service can be performed to both a mobile station and a base station by using a unified call control protocol such as SIP on an IP network, and can contain mobile stations and base stations of existing wireless facilities. The communication system in which the semi-duplex many-to-many multicasting service is performed to plural mobile stations 100a, 100b 100c and 110 includes a gateway 104a to convert a first protocol to connect the mobile station 100a, a base station 101a and the gateway 104a, and a second protocol to connect the gateway 104a, a call control server 105 and a press-talk server 106. The gateways 104a, 104b, 104c and 114a perform the protocol conversion for both communication to the mobile station and communication to the base station, so that the semi-duplex many-to-many press-talk can be realized.

Abstract: A wireless system includes plural different access networks and terminals (19, 20) having interfaces corresponding to the plural different access networks (3, 5, 9, 13). Each of the access networks includes an access gateway (AGW) performing flow control. Upon receiving a packet transmission stop signal, the AGW determines whether a predetermined message transmitting chance is given. The AGW includes a control unit that transmits a message that requests a handover to another access network to a terminal when the message transmitting chance is given. The terminal includes a unit that performs a handover to another access network, upon receiving the message.

Abstract: Disclosed herewith is a communication system, which can solve the following conventional problem that if packets exchanged between a terminal and an HA are encapsulated with use of the mobile IPv6 protocol, the PDSN cannot identify any IP flows in the mobile IPv6 tunnel. Consequently, there is no QoS usable appropriately to the services in the EV-D0 RAN. To solve such a problem, the PCRF notifies the HA of the filter information used to specify each IP flow and the flow label assigned to each IP flow. The HA then sets the flow label in the outer IPv6 header of the packet matching with the filter information and transfers the packet to the object unit. The PDSN then refers to the flow label set in the outer IPv6 header to identify the object IP flow in the mobile IPv6 tunnel. Consequently, a proper QoS can be usable for the services respectively in the EV-D0 RAN.

One end side of the lift cylinder is pivotally attached, on a vehicle body side, at a position upward of a vehicle body-sided pivotally supporting portion of the tilt cylinder.

Abstract: A public mobile terminal can use both of a public mobile communication service and an extension service while protecting an SIP message by an IP sec. An indoor call control apparatus that receives an INVITE message from the public mobile terminal has a destination determination table that determines whether the called terminal is an indoor terminal, or not. When the terminal is the indoor terminal, a Route header is deleted from the INVITE message, and the message is transmitted to the called terminal. When the called terminal is not the indoor terminal, the INVITE message is transmitted to an S-CSCF of a calling terminal on the basis of the contents of the Route header.

Abstract: When congestion occurs in a RAN in a cell phone VoIP service, calls using the congested device are detected to permit generation of a restriction in call by call units. The congested device notifies call connection data passing through it to a PDSN, the PDSN finds the IP address of the terminal using the target connection, and notifies a CSCF as a restriction target terminal. The CSCF, in call connection processing, determines whether the calling/called sending/receiving user is the restriction target, and if so, determines whether or not the call should be connected with priority from subscriber data.
