    • A system and method of operating a communication system is described. A communication interface receives a first user request for a voice service from a communication device. In response to receiving the first user request, the communication interface transfers an initial message requesting access to the voice service. The communication interface receives a response to the initial message that indicates that the voice service is not available. After receiving the response, the communication interface receives a second user request from the communication device. A processing system processes the second user request to determine if the second user request indicates an emergency service. If the second user request indicates the emergency service, then the communication interface transfers a call request for the emergency service. If the second user request does not indicate the emergency service, then the communication interface notifies the communication device that the voice service is not available.
    • 描述操作通信系统的系统和方法。 通信接口从通信设备接收用于语音服务的第一用户请求。 响应于接收到第一用户请求,通信接口传送请求接入语音服务的初始消息。 通信接口接收到表示语音服务不可用的初始消息的响应。 在接收到响应之后,通信接口从通信设备接收第二用户请求。 处理系统处理第二用户请求以确定第二用户请求是否指示紧急服务。 如果第二用户请求指示紧急服务,则通信接口传送紧急服务的呼叫请求。 如果第二用户请求没有指示紧急服务,则通信接口通知通信设备语音服务不可用。

    • A call control system comprises a communication interface and a processing system. The communication interface is configured to receive a first access request from a communication system requesting access to a voice service. The communication interface is configured to, in response to receiving the first access request, transfer a rejection to the communication system that indicates that the voice service is not available. The communication interface is configured to, in response to transferring the rejection, receive a first call request for a priority service from the communication system. The processing system is configured to process the first call request to determine if the first call request indicates the priority service. If the first call request indicates the priority service, then the communication interface is configured to transfer a second access request to a communication network in response to the first call request. The communication interface is configured to, in response to transferring the second access request to the communication network, receive a first successful response from the communication network. The communication interface is configured to, in response to receiving the first successful response, transfer a second call request to the communication network.
    • 呼叫控制系统包括通信接口和处理系统。 通信接口被配置为从请求接入语音服务的通信系统接收第一接入请求。 通信接口被配置为响应于接收到第一接入请求而将拒绝传送到指示语音服务不可用的通信系统。 通信接口被配置为响应于传送拒绝,从通信系统接收优先服务的第一呼叫请求。 处理系统被配置为处理第一呼叫请求以确定第一呼叫请求是否指示优先级服务。 如果第一呼叫请求指示优先级服务,则通信接口被配置为响应于第一呼叫请求将第二接入请求传送到通信网络。 通信接口被配置为响应于将第二接入请求传送到通信网络,从通信网络接收第一成功响应。 通信接口被配置为响应于接收到第一成功响应,将第二呼叫请求传送到通信网络。
