Embodiments of the present invention disclose an access network node, a core network node, and a paging method, and relate to the communications field, so as to resolve a problem that an M2M service cannot be normally used because a network side cannot determine whether a coverage enhancement technology needs to be used in a paging process. A specific solution is as follows: A communications interface is configured to receive a first packet paging message sent by a core network node; a processor determines, according to the first packet paging message received by using the communications interface, that a terminal is an M2M terminal; and a transmitter sends a coverage-enhanced second packet paging message to the terminal. The present invention is used in a paging process.

A communication method, an access network device, and a terminal, the method comprising sending, by a first access network device, in a cell of the first access network device and corresponding to a radio network area of a terminal in a radio resource control (RRC) inactive state, and in response to the terminal in the RRC inactive state needing to be paged, a first paging message paging the terminal and sending, by the first access network device to a second access network device, a paging request message requesting to page the terminal, where the second access network device is an access network device other than the first access network device, and where the second access network device corresponds to the radio network area.

A paging method, includes: in response to determining that user equipment (UE) to which a Subscriber Identification Module (SIM) card to be paged belongs is multi-SIM user equipment and multiple SIM cards of the multi-SIM UE belong to a same network operator's network, determining a first base station accessed by the connected SIM card of the multi-SIM user equipment; and sending paging signaling for paging the SIM card to be paged to the first base station.

This patent document describes, among other things, techniques, and apparatuses for providing paging carrier selection based on a coverage enhancement level (CEL) and associated carrier specific configuration. In one aspect, a method of wireless communication is disclosed. The method includes receiving, by a wireless device, from a first network node, a paging radio resource specific paging configuration, selecting, by the wireless device, a paging radio resource based on a paging radio resource specific paging configuration, wherein the selecting further uses a wireless device specific paging configuration in case that the wireless device is configured with the wireless device specific paging configuration, and performing a further communication operation based on the paging radio resource that is selected by the wireless device.

A communication method relates to a paging mechanism applied for a radio access network, including: a centralized unit sends a paging message to a distributed unit, where the paging message carries indication information indicates that the paging is paging originated from a core network or the paging is paging originated from a radio access network; and the distributed unit determines, according to the indication information, that the paging is paging originated from the core network or the paging is paging originated from the radio access network.

Method for scheduling paging in telecommunication network making the list candidate base station to send paging message. This method based on the Haversine formula to calculate distance between pair of base station from position information (latitude, longitude) and filter by situation: Distance=<Δ*Min (which Δ is 3) to make the list candidate base station for each of base station in list input. This method is useable for the telecommunication system which need to page UE for mobile terminated (MT) service.

Embodiments include methods in a wireless device. Such methods include, while the wireless device is in a Radio Resource Control (RRC) inactive state with respect to a wireless communication network, determining that a Radio Access Network Notification Area Update (RNAU) is needed. Such methods include evaluating whether there is any cause, other than the determined need for the RNAU, for resuming an RRC connected state with the wireless communication network and transmitting, to the wireless communication network, an RRC Resume Request message comprising a cause indicator indicating a cause for resuming the RRC connected state. The cause indicator indicates an RNAU when there is no cause for resuming the RRC connected state other than the determined need for the RNAU and otherwise indicates a cause other than an RNAU. Other embodiments include wireless devices configured to perform such methods and computer-readable media that store instructions embodying such methods.

A mobility management processing method and apparatus are disclosed. The method includes: receiving, by an SMF network element, a data notification message that includes a PDU session identifier and that is sent by a UPF network element, and determining, based on the PDU session identifier, a session and SSC mode corresponding to the PDU session identifier and/or a service area of the UPF network element, where the UPF network element is a network element that establishes a PDU session corresponding to the PDU session identifier; determining a paging area based on the SSC mode and/or the service area of the UPF network element; and sending a first message including the paging area to an AMF network element, where the first message is used to trigger the AMF network element to page, in the paging area, a terminal that establishes the PDU session by using the UPF network element.
