Abstract: A network node for a communication system is associated with a serving public land mobile network (PLMN) for a first client device. The network node is configured to transmit a first control message to the first client device in response to determining that the serving PLMN for the first client device is in a disaster condition. The first control message indicates that the serving PLMN for the first client device is in the disaster condition.

Abstract: A client device for efficient disaster handling based on a novel list of PLMNs for disaster conditions. The client device is provided with a list of PLMNs that is used by the client device in response to the serving PLMN of the client device going into a disaster condition. Upon determining that the serving PLMN is in a disaster condition, the client device registers at a visiting PLMN in the PLMN list. The novel list of PLMNs for disaster conditions enables the client device to roam into PLMNs which is forbidden during normal conditions.

Abstract: This application provides a method and an apparatus for switching an RRC state. The method includes: sending, by a communications apparatus, indication information to a network device, where the indication information is used to indicate that the communications apparatus requests to enter an RRC inactive state; after completing a registration process of an RRC connected state, receiving, by the communications apparatus, an RRC connection release message that is sent by the network device based on the indication information, where the RRC connection release message is used to indicate the communications apparatus to enter the RRC inactive state; and entering, by the communications apparatus, the RRC inactive state from the RRC connected state based on the RRC connection release message. In this way, energy consumption of the terminal-side communications apparatus can be effectively reduced, and network resource consumption can also be reduced.

Abstract: The present invention provides a cell selection method and apparatus. The cell selection method includes: sending, by a non-access stratum of user equipment UE, network list information to an access stratum of the UE, where the network list information includes a list of forbidden networks and a list of forbidden networks for a GPRS service; determining, by the non-access stratum, indication information about a cell selection priority according to an operation mode of the UE; and sending, by the non-access stratum, the indication information to the access stratum, so that the access stratum selects a suitable cell according to the network list information and the indication information. The present invention can effectively prevent the UE from entering a state of being able to normally camp but unable to obtain a normal service, thereby improving user experience.

Abstract: Embodiments of the present invention provide a mode switching method and apparatus, which relate to the communications field and are used to improve user experience. The method includes: when a user equipment UE is in a state of accessing a first network in a first network mode of a first communications mode, determining, by the UE, whether the first network supports a first subsystem; enabling, by the UE, if the UE determines that the first network does not support the first subsystem and when the UE does not access a second network in the first communications mode, a second communications mode and accessing the second network in the second communications mode; and sending, by the UE, a first registration request message to the second network. The embodiments of the present invention are applicable to a service transmission scenario.
