摘要： The present invention discloses a communication method, including: sending, by a mobility management entity MME, a bearer setup request message to an evolved NodeB eNodeB, where the bearer setup request message is used to instruct the eNodeB to set up a voice bearer for user equipment; and when the MME receives a bearer setup failure message sent by the eNodeB in response to the bearer setup request message, sending, by the MME, an indication message to the user equipment, where the indication message is used to indicate that a voice over Internet Protocol IP multimedia subsystem IMS VoIMS of the user equipment is unavailable. According to the solution provided in an embodiment of the present invention, when setup of a voice bearer of a VoLTE call fails, the user equipment is notified that a VoLTE is unavailable, so that the user equipment can be prevented from continuing attempting to initiate the VoLTE call and exacerbating cell congestion.
摘要翻译：本发明公开了一种通信方法，包括：移动管理实体MME向演进基站eNodeB发送建立承载请求消息，该承载建立请求消息用于指示eNodeB为用户建立语音承载设备; 当所述MME接收到所述eNodeB响应所述承载建立请求消息发送的承载建立失败消息时，所述MME向所述用户设备发送指示消息，所述指示消息用于指示互联网语音用户设备的协议IP多媒体子系统IMS VoIMS不可用。根据本发明实施例提供的方案，当VoLTE呼叫的语音承载建立失败时，通知用户设备VoLTE不可用，从而可以防止用户设备继续尝试发起 VoLTE呼叫并加剧细胞堵塞。

摘要： The present invention discloses a method, device and system for transmitting packet service data. The method includes the steps of: receiving the packet service data transmitted by a user equipment; determining the packet service data to be uninstalled in the packet service data according to the service uninstall strategy of the user equipment; and transmitting the packet service data to be uninstalled to the packet data network via a metropolitan-area network and an internet protocol (IP) backbone network. By applying this invention, the problem is overcome that all packet service data transmitted by the user equipment need to be transmitted via a mobile backhaul, a radio network controller (RNC), a serving GPRS support node (SGSN), the IP backbone network and a gateway GPRS support node (GGSN) in the prior art, thereby saving the operation and maintenance cost of the packet network.
