Abstract: The present disclosure relates to an SMS processing method in an Internet of Things, a mobility management network element, and a terminal device, to provide an SMS service for an Internet of Things terminal device. One example method includes receiving, by a mobility management network element in a packet switched (PS) domain, a non-combined registration request from a terminal device. The non-combined registration request carries SMS only indication information. When determining that the mobility management network element in the PS domain cannot transfer an SMS for the terminal device through the PS domain, the mobility management network element in the PS domain sends a location update request to a mobility management network element in a circuit switched (CS) domain The location update request is used to implement registration of the terminal device with the CS domain.

Abstract: This disclosure discloses communication methods and apparatuses. One example method includes: obtaining slice information of a session, sending a first message to a network function repository function network element, and receiving identification information of an intermediate session management function network element from the network function repository function network element. The intermediate session management function network element is configured to manage an intermediate user plane function network element, and the intermediate user plane function network element is configured to forward service data between an access network device to which a terminal is connected and an anchor user plane function network element in response to the terminal moving out of a service area of the anchor user plane function network element and a service area of an anchor session management function network element.

Abstract: The present disclosure relates to example SMS processing methods in an Internet of Things, mobility management network elements, and terminal devices, to provide an SMS service for an Internet of Things terminal device. One example method includes receiving, by a mobility management network element in a packet switched (PS) domain, a non-combined registration request from a terminal device, where the non-combined registration request carries SMS only indication information. When determining that the mobility management network element in the PS domain cannot transfer an SMS for the terminal device through the PS domain, the mobility management network element in the PS domain sends a location update request to a mobility management network element in a circuit switched (CS) domain The location update request is used to implement registration of the terminal device with the CS domain.
