    • A gateway apparatus is provided in which multi-media services, such as video phone (TV telephone), employing a network of a mobile circuit switched network or the protocol for mobile circuit switching, and the mobile IMS network, are interconnected, and in which a mobile terminal for circuit switching and a mobile terminal for mobile IMS may be interconnected to implement integrated services as IMS. corresponding communication method and a corresponding program A gateway apparatus (110) that interconnects a mobile circuit switched network (130) and a mobile IMS network (102) to implement the video phone includes a conversion unit. The conversion unit demultiplexes a multiplexed bit stream signal output from a mobile terminal (120) connected to the mobile circuit switched network to take out one or more of a control signal, a compression-encoded speech signal, and a compression-encoded video signal. The conversion unit converts the control signal into one or more of a MEGACO signal, a SIP signal and a SDP signal, while converting the speech signal and the video signal, if necessary. The conversion unit also packetizes the speech signal and the video signal to transmit the resulting packet to the IMS network ( Fig.1 ).

    • A communications processing device that reduces the time after call disconnection until call reconnection, by using a message having a higher delivery probability than a handover instruction, when wireless quality could result in handover instruction failure. The communications processing device comprises: a measurement report acquisition unit that obtains a measurement report relating to a communications environment from a mobile communications terminal located within the cell; a wireless quality determination unit that determines whether or not the quality of wireless communications with the mobile communications terminal, included in the measurement report, is lower than a threshold value; and a message transmission unit that, if the wireless quality is less than the threshold value, sends to the mobile communications terminal a message that has less data volume than a handover instruction message and includes the carrier frequency for the base station to be handed over.
    • 一种通信处理设备,当无线质量可能导致切换指令失败时,通过使用具有比切换指令更高的传送概率的消息来减少呼叫断开之后直到呼叫重新连接的时间。 通信处理装置包括:测量报告获取单元,从位于小区内的移动通信终端获取与通信环境相关的测量报告; 确定包括在测量报告中的与移动通信终端的无线通信的质量是否低于阈值的无线质量确定单元; 以及消息传输单元,如果无线质量小于阈值,则向移动通信终端发送具有比切换指令消息更少的数据量的消息,并且包括要移交的基站的载波频率的消息。
