Abstract: According to a method and apparatus for controlling data transmission in a wireless communications network, a service quality request message is sent to a PCRF when a data request message of a terminal is received; and the PCRF queries a current network status, so as to determine a processing instruction for a data request message of the terminal according to the current network status and the data request message, and process the data request message of the terminal according to the processing instruction. Therefore, processing on the data request message of the terminal not only depends on a parameter carried in the data request message of the terminal, but also uses the current network status as a constraint condition, so that a processing manner for the data request message can be adaptive to a real-time change of the wireless communications network.

Abstract translation: 根据用于控制无线通信网络中的数据传输的方法和装置，当接收到终端的数据请求消息时，向PCRF发送业务质量请求消息; 并且PCRF查询当前网络状态，以便根据当前网络状态和数据请求消息确定终端的数据请求消息的处理指令，并根据处理指令处理终端的数据请求消息 。 因此，对终端的数据请求消息的处理不仅取决于终端的数据请求消息中携带的参数，而且还使用当前的网络状态作为约束条件，使得数据请求消息的处理方式可以 适应于无线通信网络的实时改变。

Abstract: Embodiments of the present disclosure provide an RTP packet transmission method and apparatus. A GCS AS or a BM-SC provides synchronization source information of the GCS AS and synchronization source information of the BM-SC for UE, so that the UE can continuously receive RTP packets. On one hand, the GCS AS (or the BM-SC) may provide the synchronization source information of the GCS AS (or the synchronization source information of the BM-SC) for the UE by sending an RTP packet. On the other hand, the GCS AS (or the BM-SC) further provides the synchronization source information of the BM-SC (or the synchronization source information of the GCS AS) for the UE. Therefore, when being in a unicast (multicast) transmission mode, the UE can obtain both of the synchronization source information of the GCS AS and the synchronization source information of the BM-SC.

Abstract: This disclosure relates to the technical field, and discloses a network access method, a terminal, an access network, and a core network. The terminal obtains, based on the network service identifier, the network slice type identifier corresponding to a service identifier, and then accesses the network slice based on the access mode corresponding to the network slice type, thereby avoiding unavailability of the service caused by a failure to correctly access the network slice and improving service quality.
