    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: The present invention discloses a method and a device for handover to a serving network. The method includes: receiving a first Handover Request sent by a BSC/RNC; sending a second Handover Request to a target MME according to the first Handover Request, where the second Handover Request includes an IMSI and first information for determining a source SGSN so that the MME sends a Context Request message including the IMSI to the source SGSN and receives context information of a UE that corresponds to the IMSI and is sent by the source SGSN. Thereby avoiding a handover failure which is caused because the MSC server and the SGSN select different MMEs, and further synchronizing PS and CS handover processes, improving handover accuracy and efficiency, and enhancing user experience.

    Abstract translation: 本发明公开了一种切换到服务网络的方法和装置。 该方法包括：接收BSC / RNC发送的第一切换请求; 根据第一切换请求向目标MME发送第二切换请求，其中第二切换请求包括IMSI和用于确定源SGSN的第一信息，使得MME向源SGSN发送包括IMSI的上下文请求消息，并且接收 与IMSI对应并由源SGSN发送的UE的上下文信息。 从而避免由于MSC服务器和SGSN选择不同的MME导致的切换失败，并且进一步使PS和CS切换过程同步，从而提高切换精度和效率，并提高用户体验。
