Abstract: Embodiments of this application provide network traffic marking and measurement methods and a node, and relate to the field of communications technologies, and specifically, to network traffic measurement and network traffic distribution. The network traffic measurement method includes: receiving, by a second node, a data packet sent by another node in a network, where the data packet is periodically marked by the another node, and each node has a different period of marking a data packet. According to the application, the second node may distinguish, based on the period of marking the data packet, traffic sent by the another node in the network, to obtain network traffic sent by the another node in the network to the second node. Upon implementing the traffic measurement method, data plane overheads can be reduced, and a hardware implementation process is simplified.

Abstract: Embodiments of this application provide a method for transmitting positioning assistance data and a device. The method includes: receiving, by a network device, at least one positioning assistance data message sent by a positioning server, where the at least one positioning assistance data message is used to carry positioning assistance data; and broadcasting, by the network device, a system message to a terminal device, where the system message is used by the terminal device to obtain the positioning assistance data. According to the embodiments of this application, the network device broadcasts the system message to broadcast the positioning assistance data. In this way, a problem of low efficiency of transmitting existing centralized positioning assistance data can be resolved, and a problem in the prior art that a positioning server needs to perform signaling communication with each terminal device in a unicast transmission scenario can be avoided, thereby reducing signaling overheads.

Abstract: The present invention relates to the mobile communications field, and in particular, to a synchronization signal sending method. A network device obtains a first signal after performing discrete Fourier transform DFT and orthogonal frequency division multiplexing OFDM modulation, or OFDM modulation on a ZC sequence whose root index is 1; the network device obtains a second signal after performing DFT and OFDM modulation, or OFDM modulation on a conjugate sequence of the ZC sequence whose root index is 1; the network device generates a synchronization signal, where the synchronization signal includes the first signal and the second signal; and the network device sends the synchronization signal to a terminal device. By using this method, when there is a relatively large frequency offset between the terminal device and the network device, an M2M service requirement can still be met.

Abstract: A downlink information receiving method and sending method, user equipment, and a network device, where a first user equipment first receives a first data packet, and the first user equipment determines whether the first data packet carries identity-related information of the first user equipment. If the first data packet does not carry identity-related information of the first user equipment, the first user equipment does not need to receive a second data packet.

Abstract: This application provides a resource configuration method. The method includes: generating, by a network device, a first signal; and sending, by the network device, the first signal to a terminal device at a target resource location. The target resource location includes at least one subframe, and the at least one subframe is an invalid subframe. This implements that the network device sends the first signal in the invalid subframe. Based on a mechanism of the invalid subframe, a terminal device that does not need to receive the first signal may postpone the invalid subframe, and a terminal device that needs to receive the first signal may receive the first signal in the invalid subframe.

Abstract: Embodiments of the present disclosure provide a method. According to the method, a mark is added to a data packet. After user equipment is handed over from an original device to a target device, and before a user plane network element receives a handover notification, the user plane network element sends, through a path used before handover, a data packet that carries a first mark to the original device. The original device modifies the first mark in the data packet to a second mark, and then forwards, to the target device, a data packet whose mark is modified and that carries the second mark. After receiving the handover notification, the user plane network element sends, to the target device, a data packet that carries a fourth mark. The target device can distinguish between sources of the received data packets based on different marks in the received data packets.
