Abstract: A data transmission control method, apparatus and system are provided. A radio communication node receives a data packet sent by a base station, where the data packet is generated by using a Packet Data Convergence Protocol protocol data unit (PDCP PDU) of the base station. The radio communication node acquires the PDCP PDU, which is used as a Radio Link Control service data unit (RLC SDU), in the data packet. The radio communication node sends data generated by using the RLC SDU to a user equipment, where a user plane connection is established between the radio communication node and the user equipment, and a control plane connection is established between the base station and the user equipment.

Abstract: Embodiments of this application provide a method, an apparatus, and a system for managing an international mobile subscriber identity (IMSI) status of a terminal device. An IMSI of a second terminal device is activated or deactivated through interaction between a first terminal device and a core network node, so that the second terminal device does not participate in activating or deactivating the IMSI of the second terminal device. Therefore, power consumption of the second terminal device can be reduced, and a requirement of an Internet of Things application scenario can be met.

Abstract: The present invention provides a wireless access point control method, a related device, and a system. An activation signal sent by user equipment is received on a radio resource corresponding to a receiving pattern of a first wireless access point, so that the first wireless access point controls itself to leave a power-saving state according to the activation signal. Therefore, the user equipment may directly send the activation signal to the first wireless access point to switch a working state of the first wireless access point from the power-saving state to a normal communication state as soon as possible. In this manner, a power-saving objective of the wireless access point is achieved, and switching of the wireless access point from the power-saving state to the normal communication state as soon as possible can also be accelerated on a basis of achieving power saving of the wireless access point.

Abstract: Embodiments of the present invention disclose terminal device, a base station, and communications methods of the terminal device and the base station. In the embodiments of the present invention, information about amounts of to-be-transmitted data of different D2D communications groups may be reported to a base station, so that the base station can separately schedule data for the different communications groups. The information about the amount of the to-be-transmitted data includes identification information of the currently-enabled communications group, and a buffer status report of a logical channel group corresponding to the currently-enabled communications group.
