摘要： PROBLEM TO BE SOLVED: To provide a service management node, a communication service provision system and a communication service provision method, capable of reducing a reception impossible time in voice incoming even when a node such as MME and MSC/VLR fails.SOLUTION: When a node (MME, MSC/VLR) fails, connection is transferred to another node. At this transfer, the MME, a service management node, issues paging to prompt a subordinate eNB to request each UE in a zone for location reregistration, only when the self-node state at receiving an incoming request by the transfer coincides with a preset condition to accept an incoming request preset in the self-node. On receiving the paging, each UE issues a location reregistration request to the eNB, and taking this opportunity, a connection to enable incoming is established, and thus, voice communication is resumed.
摘要翻译：要解决的问题：提供即使在诸如MME和MSC / VLR之类的节点出现故障的情况下，也能够减少语音进入中的接收不可能时间的服务管理节点，通信服务提供系统和通信服务提供方法。解决方案：当节点（MME，MSC / VLR）发生故障时，连接被传送到另一个节点。在这种传输中，MME是服务管理节点，只有当通过传送接收到传入请求的自身节点状态与预设条件一致时才发出寻呼以提示下属eNB请求用于位置重新注册的区域中的每个UE 接受在自身节点中预设的传入请求。在接收到寻呼时，每个UE向eNB发出位置重登录请求，并且借此机会建立一个能够进入的连接，从而恢复语音通信。版权所有（C）2013，JPO＆INPIT
