Abstract: Embodiments provide a network access method and a device. In accordance with the method, a preamble sequence may be received by a second network device from a terminal device on a time-frequency resource occupied by the preamble sequence. A transmit beam may be determined for sending an access response message to the terminal device. The access response message can be sent to the terminal device using the transmit beam. The second access device can send the access response message to the terminal device through beamforming, so that a coverage area of the second access device can be enlarged, directivity of data sent to the terminal device can be improved, and a probability that the terminal device receives the access response message is improved. Therefore, a rate that the terminal device succeeds in accessing the second access device is improved.

Abstract: Embodiments of the present application relate to the communications field, and provide example random access methods, apparatus, and systems, so that a terminal can access a beam in time. An example solution includes receiving, by a terminal, a plurality of signals sent by a first access device on a plurality of beams. A beam of a strongest signal in the plurality of beams is determined and a preamble signal for the beam of the strongest signal is generated. The preamble signal of the beam of the strongest signal is sent to the first access device, so that the first access device identifies, based on the received preamble signal, the beam selected by the terminal to access.

Abstract: The present application discloses a wireless local area network access point search method, an apparatus, and a system, relates to the field of communications technologies, and can reduce power consumption for passive scanning. According to the method, beacon sending information of a wireless local area network access point and measurement information of a user equipment are matched, so that the user equipment can search for the wireless local area network access point only at the time when and a frequency channel number at which the wireless local area network access point sends a beacon. Compared with the prior art in which a user equipment needs to continuously keep a state of searching for a wireless local area network access point, the present application greatly shortens time spent by the user equipment in listening to a beacon, and therefore reduces power consumption of passive scanning.

Abstract: This application provides a communication method, apparatus, and system. The communication method includes: A first access network device (an indoor base station) obtains first information, and then sends the first information to a core network device through a control plane of a next generation (NG) interface or a general packet radio service tunnelling protocol for the user plane (GTP-U) tunnel between the first access network device and the core network device. The first information transmitted on the control plane of the NG interface or the GTP-U tunnel needs to pass through a route of a second access network device (an outdoor base station). According to this method, the indoor base station may perform NG interface-based communication with the core network device via the outdoor base station, to provide a better home network service.
