Abstract: This application provides a method for processing a network registration anomaly, an apparatus, and a storage medium. In a 5G SA network registration process, if an anomaly occurs in a registration, a terminal device obtains registration failure cause information and a cumulative failure count, to determine whether a condition for ending the registration early is met. If the condition is met, the 5G SA network registration process is ended early, and there is no need to re-attempt for five times according to a protocol.

If the condition is met, the 5G SA network registration process is ended early, and there is no need to re-attempt for five times according to a protocol, thereby quickly falling back to an LTE network to resume services.

Abstract: A method for improving a paging response speed of a user equipment (UE), includes: camping, by the UE on a first cell of a first network, the UE being in an RRC connected state; when a first preset condition is met, sending, by an access network device, a first message to the UE, the first message being used to indicate the UE to enter an RRC inactive state; recording, by the access network device, that the UE is in an RRC inactive state; and in response to the first message that is received, entering, by the UE, the RRC inactive state; and when a second preset condition is met, camping, by the UE, on a second cell of the first network, where the UE is in an RRC inactive state, and the first cell and the second cell are the same or different.

Abstract: Embodiments of this application provide a cell selection method and an apparatus, and relate to the communications field. A terminal may determine a first measurement frequency and a 5G anchor cell at the first measurement frequency based on prior historical information. The terminal may shorten evaluation duration corresponding to a 5G anchor cell that meets a preferred condition at a first measurement frequency, so as to improve a probability that the terminal camps on the 5G anchor cell.

Abstract: A switching method and a terminal device, which relate to the communications field. The switching method comprises: establishing, by a terminal device, a first packet data network PDN connection in a long term evolution LTE access network; switching, by the terminal device, the first PDN connection from the LTE access network to a wireless local area network WLAN access network; establishing, by the terminal device, a second PDN connection in the LTE access network, so that the terminal device is in a registered state in the LTE network; and switching, by the terminal device, the first PDN connection or a third PDN connection established in the WLAN access network, to the LTE access network.
