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: The present application discloses a DCN processing method for a PLMN that is applied to a network sharing scenario. An access feedback message of a network side is received, and selection assistance information of a DCN and an identifier of a PLMN that serves UE are obtained from the access feedback message, so as to know a PLMN that is actually accessed by the UE. A correspondence between the selection assistance information of the DCN and the identifier of the PLMN that serves the UE is stored. When the UE moves to coverage of the PLMN, a requested DCN to be accessed can be directly determined according to the correspondence, and a RAN node is requested to access the determined DCN. Therefore, a redirection process is reduced, and resource overheads are 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: The present invention relates to the field of communications technologies and discloses a method for selecting an LTE network and a device, so as to ensure continuity of a PS service, avoid unnecessary inter-PLMN handover, and improve user experience. The method mainly includes: acquiring, by an MSC/VLR, an identity of an LTE PLMN in which UE is registered, where the MSC/VLR is an MSC/VLR after the UE falls back to a 2G/3G network because of performing a CS service; and sending, by the MSC/VLR, a notification message to the UE, where the notification message includes the identity of the LTE PLMN, which is used to indicate the LTE PLMN that the UE returns to, and the LTE PLMN is used as a registered PLMN in the 2G/3G network. Embodiments of the present invention are mainly used in a process of fallback to an LTE network after a CSFB service ends.
