A cell selection method, related to the communications field, includes a terminal device sending a first request to a network device, where the first request is used to request to select a serving cell for the terminal device in an energy efficiency first manner. The terminal device sends first information to the network device, where the first information is used by the network device to select a cell in a first communications system or a cell in a second communications system for the terminal device. The terminal device receives configuration information of a serving cell from the network device, where the serving cell is selected by the network device from the cell in the first communications system or the cell in the second communications system in a manner that energy efficiency of the terminal device is first.

This application discloses a cell camping method and an apparatus. The method includes: After a terminal device camps on a first cell, a network device may send a first message to the terminal device, where the first message includes information about a second cell, the first cell corresponds to a first CC, and the second cell corresponds to a second CC; after receiving the first message, the terminal device sends a second message to the network device, where the second message may indicate the first cell and/or the second cell, or the second message may include measurement information of the first cell and/or the second cell; and the network device may determine, based on the second message, that the terminal device camps on the first cell or the second cell. This ensures network load balancing between different cells.

The present application relates to a network slicing information processing method, a terminal device, and a network device. The method comprises: the terminal device receives first information, the first information comprising network slicing information and a limiting condition corresponding to the network slicing information, and the first information being used for determining priority information of a cell or frequency point by the terminal device when performing cell selection or reselection. Embodiments of the present application can be used for determining the cell or frequency point priority information by the terminal device when performing the cell selection or reselection.

A network access method and a terminal are provided. The network access method performed by the terminal includes receiving a reference signal transmitted by a network-side device. The reference signal includes a first reference signal, or includes a first reference signal and a second reference signal. The first reference signal is an Single-Frequency Network (SFN)-specific reference signal, or the second reference signal is a cell or Transmission Reception Point (cell/TRP)-specific reference signal. The network access method further includes performing an initial access-related operation based on the received reference signal.

A user device, such as a vehicle, may find a suitable base station for communication according to a hailing message. A low-complexity hailing procedure, suitable for adding to 5G and 6G standards, is presented. The hailing message may be a brief code indicating that it is a hailing message, and therefore solicits a reply. The hailing message may further include the identification or location of the user device, and/or an indication of which type of entity is being sought, such as a base station. The base stations that receive the hailing message can reply after a calculated delay time, such as a longer delay time if the received amplitude is weak, so that the user device can select whichever base station has the best received signal. Alternatively, the user device can select the base station with the largest received amplitude of the reply message.
