Abstract: A method, an apparatus, and a system for detecting a radio network problem are disclosed. The method includes: when a radio network problem occurs on a user equipment (UE), a first base station controlling a cell that a radio resource control (RRC) connection established with the UE, receives problem information about the radio network problem sent by the UE, in a procedure of re-establishing the RRC connection by the UE, and sends the problem information to a second base station controlling a cell where the radio network problem occurs.

Abstract: This application provides a measurement method, a terminal device, and an access network device. The measurement method includes: measuring, by a terminal device, signal quality of a plurality of beams, where the signal quality of the plurality of beams is obtained by using synchronization signal blocks; the signal quality of the plurality of beams includes signal quality of a same beam at different moments, and the plurality of beams belong to one cell; and obtaining, by the terminal device, signal quality of the cell based on the signal quality of the plurality of beams. In this way, cell measurement based on a synchronization signal is implemented, and the signal quality of the cell obtained based on the signal quality of the plurality of beams at the different moments is more accurate.

Abstract: This application provides a network selection method, a network device, and a terminal device. The network selection method mainly includes: A first network device sends a first message to a terminal device. The first message includes a message that indicates the terminal device to measure a cell of a first-type network, the first-type network is a high-priority network selectable for the terminal device, and a network provided by the first network device does not belong to the first-type network.

Abstract: In one embodiment, a policy may be defined, which specifies that an operation be performed over a first set of channels before being performed over a second set of channels different than the first set of channels. The first set of channels may be associated with a first set of frequencies, and the second set of channels may be associated with a second set of frequencies. A network device may perform paging according to the defined policy. A user equipment (UE) may perform paging, page monitoring, cell selection triggered by paging, or cell reselection triggered by paging according to the policy. The policy may be hardcoded, pre-configured or dynamically configured using signaling messages.
