Embodiments of the present invention, relating to the communications field, disclose a paging method, apparatus, and system. A specific solution comprises receiving a first paging message from a core network node, wherein the first paging message is used to page a terminal, and the first paging message comprises channel loss information of the terminal, and sending control information with enhanced coverage to the terminal in response to the first paging message.

A network node in a cellular communications network allocates a mobility area to a user equipment device, such that the user equipment device is not required to inform the network of its location while it remains in the mobility area. The mobility area comprises a plurality of tracking areas, and each tracking area has a respective identifier comprising a plurality of bits. The network node provides information to the user equipment device identifying the plurality of tracking areas forming the mobility area allocated to the user equipment device, wherein said information identifying the plurality of tracking areas forming the mobility area comprises fewer bits of information than the total number of bits in the respective identifiers of the plurality of tracking areas.

The present disclosure relates to a communication technique for combining, with an IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and to a system therefor. The present disclosure may be applied to intelligent services (e.g., a smart home, a smart building, a smart city, a smart car or connected car, healthcare, digital education, retail business, security and safety-related service, etc.), based on a 5G communication technology and an IoT-related technology. A method for a user equipment in a first communication system according to the present invention comprises steps in which a user equipment in an inactive state: transmits a paging area update request message; checks whether or not a timer associated with a paging area update has expired; and transitions into an idle state if a response message for the paging area update request message has not been received until the timer has expired.

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.

Disclosed herein are methods and apparatus for coverage determination and download opportunity notification. A method for content coverage determination and download opportunity includes obtaining, by a content coverage application running on a mobile device, an itinerary from a map application on the mobile device. The content coverage application sends the itinerary and mobile device characteristics to a coverage determination system and receives a wireless coverage profile based on the itinerary and the mobile device characteristics. The content coverage application generates a list of entertainment applications running on the mobile device. The content coverage application provides a notification of a wireless coverage gap based on the wireless coverage profile and displays the list of entertainment applications and status for each listed entertainment application in response to user input. The content coverage application sends instructions to one or more of the listed entertainment applications to download content in response to user selections.
