    • Communication is carried out on the basis of an optimum speech coding scheme that is matched to the speech coding schemes provided by the radio zones, and to the speech coding capabilities of the mobile stations. To achieve this, when a traffic channel is set up between a mobile station and a switch, a traffic channel selection condition that has been specified by the switch on the basis of the speech coding capabilities of the mobile station that made the SETUP request and of the mobile station to which the call is made, is stored in the control station. The control station grasps which speech coding scheme is currently being used in the radio zone which it controls. Moreover, by transferring the selection conditions specified by the switch and using these conditions as information required for channel setup by another control station, communication can be carried out using a high-priority speech coding scheme when handover occurs. This happens when channel selection takes place in another radio zone spanning control stations, or when a mobile station has moved to a radio zone in which a high-priority speech coding scheme can be used. As a result, traffic channels based on the optimum speech coding scheme can be changed over smoothly.
    • 基于与无线电区域提供的语音编码方案匹配的最佳语音编码方案以及移动台的语音编码能力进行通信。 为了实现这一点,当在移动台和交换机之间建立业务信道时,基于进行SETUP请求的移动台的语音编码能力由交换机指定的业务信道选择条件和 进行呼叫的移动台被存储在控制站中。 控制台掌握其控制的无线电区域中当前正在使用哪个语音编码方案。 此外,通过将由交换机指定的选择条件和使用这些条件作为由另一控制站进行信道建立所需的信息,可以在切换发生时使用高优先级语音编码方案进行通信。 当频道选择发生在跨越控制站的另一无线电区域中时,或者当移动台已经移动到可以使用高优先级语音编码方案的无线电区域时,会发生这种情况。 结果,可以顺利地改变基于最佳语音编码方案的业务信道。

    • A communication device includes a network side communication unit that receives emergency information from an information broadcasting node; a UE side communication unit that communicates a communication signal with user equipment through a radio base station; and a determination unit that determines whether to allow state transition, when the UE side communication unit receives a request signal requesting the state transition of an RRC protocol state from the user equipment, subsequent to broadcasting a Primary Notification signal providing notice of broadcasting of the emergency information. When the state transition is from a state in which receiving of the emergency information is enabled to a state in which receiving of the emergency information is disabled, the determination unit determines to disallow the state transition, and broadcasts a Secondary Notification signal including the emergency information.

    • An appropriate selection is controlled for selecting an extension transmitting/receiving server device for transmitting or receiving user data, to be transmitted or received between mobile station devices, to or from a radio base station device by employing extension transmission or reception of data, in a radio access network relaying data between a core network having a mobile switch station and the mobile station devices. While referring to a management table for managing statuses of extension transmitting/receiving server devices 30a to 30c, at least one of the extension transmitting/receiving server devices 30a to 30c is selected. The user data transmitted or received between mobile station devices through the selected extension transmitting/receiving server device is transmitted. This allows the control of an appropriate selection from the extension transmitting/receiving server devices.
