  • Publication number: 20230388957
    Abstract: This application discloses a communication method and apparatus. The method includes: A UE sends a registration request message to an AMF, where the registration request message includes indication information, and the indication information indicates whether a disaster scenario exists. The AMF receives the registration request message, and sends a registration response message to the UE based on the indication information and a load status. The UE receives the registration response message.

  • Publication number: 20230337167
    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.

  • Publication number: 20230328833
    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.

  • Patent number: 11483894
    Abstract: Example embodiments of the present disclosure provide a method and a communications 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 received 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.

  • Patent number: 10667203
    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.
