摘要： Embodiments of this application provide a method for sending accuracy information, an apparatus, and a system. The method includes: A first network element switches from a locked state to a holdover state; and the first network element sends state information to a second network element, where the state information includes accuracy information of the first network element in the holdover state. According to the foregoing method, the second network element may obtain state information of the first network element in the holdover state, and perform clock synchronization with the first network element or the second network element based on the state information, to finally implement more accurate clock synchronization and further improve performance of a clock synchronization system.

摘要： This application provides a method for identifying GNSS pseudolite data. The method is applied to the communications field, and includes: A target device receives first data sent by an access network device, where the first data includes first ephemeris information and/or first almanac information. The target device determines abnormal first data based on a plurality of pieces of first data, where the plurality of pieces of first data include the abnormal first data, the plurality of pieces of first data are obtained by the target device from a plurality of access network devices, and a plurality of pieces of first ephemeris information and/or a plurality of pieces of first almanac information in the plurality of pieces of first data correspond to a first satellite. The target device may determine, by using the plurality of pieces of first ephemeris information and/or the plurality of pieces of first almanac information, that a piece of first ephemeris information and/or a piece of first almanac information is abnormal. Therefore, GNSS pseudolite data can be identified, thereby providing a basis for corresponding protection.

摘要： This application discloses a GNSS signal distribution system and a GNSS base station. The GNSS signal distribution system includes at least two BBUs and a rack-type power splitter connected to each of the at least two BBUs. A slot supporting insertion and removal of at least one type of card is disposed on the rack-type power splitter. After a card is inserted into the slot, the card is connected to the rack-type power splitter. The rack-type power splitter can process a GNSS signal based on a functional module in the card, and distribute a processed GNSS signal to each BBU. Based on such a system, when a base station function is deployed in a base station, only a card with a corresponding function needs to be inserted into the slot based on a requirement. This can well reduce deployment difficulty and costs of the GNSS base station. In addition, a problem that an extra space needs to be occupied to separately dispose a power splitter, a surge protector, an amplifier, a fiber transmission component, or the like can be avoided, thereby improving effective space utilization of an equipment room.

摘要： Embodiments of the present invention disclose a data transmission method, so as to transmit a frame number and a frame phase of a CPRI data frame in Ethernet. The present invention further provides a corresponding communications device and communications system. In some feasible implementation manners of the present invention, the method includes: selecting, by a first communications device, a CPRI data frame, and converting a frame number of the selected CPRI data frame into a value of a second; generating a pulse per second signal, where a phase of the pulse per second signal is a frame phase of the selected CPRI data frame; generating a timestamp according to the pulse per second signal and the value of a second; and sending, to a second communications device, a synchronization message that carries the timestamp, to enable the second communications device to obtain the frame number and the frame phase of the selected CPRI data frame according to the timestamp.
