Abstract: Embodiments of the present invention disclose a method for a handover from a circuit switched domain to a packet switched domain, a device, and a communications system. One of CS to PS handover methods includes receiving, by a target mobility management entity, a CS to PS handover request message that corresponds to a first UE and is from an MSC; triggering setup of a dedicated VoIP bearer that corresponds to the first UE and is between an SGW and an MGW; sending a handover request message to a target access network to instruct the target access network to prepare a handover resource for the first UE; and sending a CS to PS handover response message corresponding to the first UE to the MSC.
Abstract translation: 本发明的实施例公开了一种从电路交换域到分组交换域，设备和通信系统的切换的方法。 CS到PS切换方法之一包括由目标移动性管理实体接收对应于第一UE并且来自MSC的CS到PS切换请求消息; 触发对应于第一UE并且在SGW和MGW之间的专用VoIP承载的建立; 向目标接入网发送切换请求消息，指示目标接入网准备第一UE的切换资源; 并向CS发送对应于第一UE的PS切换响应消息。

Abstract: This application provides a data transmission method and apparatus. The method includes: receiving, by a first network node, first indication information sent by a second network node, where the first indication information is used by the first network node to determine first duration, and the first duration is duration from receiving a first data packet by the first network node to sending the first data packet by the first network node; and sending, by the first network node, the first data packet based on the first indication information. The data transmission method and apparatus provided in embodiments of this application help ensure that a communications network transmits a data packet based on a duration requirement.

Abstract: A method, device and system for implementing optimized inter-RAT handover are disclosed. In the method, a user equipment or a source network decides to prepare for a handover to a target network. A corresponding target network ID is obtained from a configured mapping between cell IDs and target IDs according to a received cell ID. Target network bearers are set up after determining an access node of the target network. The user equipment is connected to the target network after handover preparation is complete.
