Abstract: Embodiments of the present disclosure disclose an identifier information updating method, a terminal, and a network device. The method includes: sending a second source L2 ID of a first terminal to a second terminal, where the second source L2 ID is different from a first source L2 ID used in a sidelink establishment request message.

Abstract: A UE reachability management method, a core network and an access network are provided. The method includes: transmitting a request message for requesting UE reachability information to an access network in a case that a UE supports a radio resource control (RRC) inactive state; receiving the UE reachability information fed back by the access network according to the request message.

Abstract: A method of processing a network slice based congestion, a device and a system thereof are provided. The method includes: receiving a message sent by a network including slice congestion information; and backing off a target network slice corresponding to the slice congestion information, according to the slice congestion information.

Abstract: Embodiments of this application provide a network attach method and user equipment. The method is applied to UE, and includes: sending a first network attach request message to a first target gateway according to the first information; where the first information is used to indicate load information of each of M gateways; the first target gateway is at least one gateway, to which the UE has never sent a network attach request message, in the M gateways; and the first network attach request message is used to request to attach to a 3GPP network through an untrusted Wi-Fi network, where M is a positive integer.

Abstract: A method for transmitting a radio capability identifier, a terminal device, and a network node are disclosed. The method includes: sending a currently available first radio capability identifier of a terminal device to a network node in a case that a network node change-related condition is satisfied.

Abstract: A method of processing a network slice based congestion, a device and a system thereof are provided. The method includes: receiving a message sent by a network including slice congestion information; and backing off a target network slice corresponding to the slice congestion information, according to the slice congestion information.

Abstract: A method for service processing and a user equipment are provided, and the method for service processing includes: starting a back-off timer, after receiving a rejection response message sent by a network side through a 3GPP access; and stopping the back-off timer and triggering a service request process that is based on the 3GPP access, when a non-access stratum notification message sent by the network side through a non-3GPP access is received before the back-off timer expires.

Abstract: The present disclosure provides a registration switching method, a request processing method, an information sending method, and a related device. The method includes: camping on a network node supporting an NB service, and performing combined registration with a network supporting the NB service and a network supporting a WB service; and switching to a network node supporting the WB service, to transmit the WB service.

Abstract: This disclosure provides an information reporting method, an information receiving method, a terminal, and a network control entity. The method includes reporting information about air interface resources used by the terminal in proximity-based communication.

Abstract: Embodiments of this disclosure provide a method and an apparatus for handling a protocol data unit session, and an electronic device. The method includes: transmitting a protocol data unit PDU session release request to a network device in a case that at least one of an authorized quality of service QoS rule, packet filter, and/or authorized QoS flow description configured by a network device for the PDU session exceeds a maximum support capability set by user equipment for the PDU session.

Abstract: Embodiments of the present invention disclose a wireless communication method and a device. The method includes: receiving a configuration update command message, where the configuration update command message is used to instruct a terminal device to release a non-access stratum NAS signaling connection with a network device and initiate a mobile registration update procedure; and if a mobility management back-off timer is running at a reception occasion of the configuration update command message, stopping the mobility management back-off timer.

Abstract: A UE reachability management method, a core network and an access network are provided. The method includes: transmitting a request message for requesting UE reachability information to an access network in a case that a UE supports a radio resource control (RRC) inactive state; receiving the UE reachability information fed back by the access network according to the request message.

Abstract: A method of processing a network slice based congestion, a device and a system thereof are provided. The method includes: receiving a message sent by a network including slice congestion information; and backing off a target network slice corresponding to the slice congestion information, according to the slice congestion information.

Abstract: Embodiments of the present disclosure provide a connection control method and device. The method includes: establishing a session connection with a network device, where the session connection is for emergency service; de-activating a mobile initiated connection only (MICO) mode locally at the UE.

Abstract: A method for service processing and a user equipment are provided, and the method for service processing includes: starting a back-off timer, after receiving a rejection response message sent by a network side through a 3GPP access; and stopping the back-off timer and triggering a service request process that is based on the 3GPP access, when a non-access stratum notification message sent by the network side through a non-3GPP access is received before the back-off timer expires.
