According to an aspect, a wireless device determines, while in an RRC Inactive state, that a Radio Access Network Notification Area Update, RNAU, is needed. The wireless device further evaluates whether there is any other cause for resuming an RRC connected state, in addition to the need for the RNAU. The wireless device transmits an RRC Resume Request message to the network, in response to the determining. The RRC Resume Request message includes a cause indicator indicating an RNAU as a cause for resuming a RRC Connected state in the event that said evaluating identifies no other cause for resuming the RRC connected state.

This application discloses a communication method and a device, and the method includes: sending, by a first base station, a first request message, where the first request message is used to request one or more second base stations located in a paging notification area of a target terminal to page the target terminal; and if the first base station receives, within preset duration, a second request message that is sent by one of the one or more second base stations and that is used to obtain a context of the target terminal, sending, by the first base station, the context of the target terminal to the second base station that sends the second request message. A terminal device in a third mode may be paged by using the method and the device in this application.

The present invention is directed to a method and an apparatus for use in a cellular communication system. Specifically, the present invention is directed to a method comprising: transmitting, to one of WLAN Terminations (WTs), a first indication to wake up WLAN module of the UE; if no response for the first indication is received from the one of WTs during a first time duration, transmitting, to all of the WTs, a second indication to wake up the WLAN module of the UE; and if no response for the second indication is received from any of the WTs during a second time duration, transmitting, to a mobility management entity (MME), a third indication related with absence of the UE, and an apparatus therefore.

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.

Provided are a method by which an access and mobility function (AMF) in a wireless communication system selectively alters a tracking area set, and a device supporting the method. The method may comprise the steps of: receiving a plurality of tracking area sets from a base station; receiving, from the base station, information about the mobility of a terminal; and selecting any one tracking area set that corresponds to the received terminal mobility information.
