Abstract: A session processing method in wireless communications and a terminal device include sending, by the terminal device, a session establishment request to a core network device, where the session establishment request requests to establish a session, and the session is supported by a network slice corresponding to the session, determining, by the terminal device, that establishment of the session fails, determining, by the terminal device, a forbidden time period corresponding to the session, and forbidding, by the terminal device, the terminal device from sending the session establishment request within the forbidden time period.

Abstract: In a communication method, a session management function network element initiates a procedure of a first operation for a first session; the session management function network element receives a request to establish user-plane resources for the first session from an access and mobility management function network element in a process of performing the first operation; and the session management function network element determines a subsequent procedure based on the first operation.

Abstract: The present invention discloses a method, including: when user equipment camps on a first network, sending, by the UE to a network device, a single-domain registration request needed when the network device performs mobility management on the UE. The single-domain registration request carries a first IE, and the first IE identifies that the UE has a CS domain voice capability. The UE is a single card dual standby terminal, the UE is currently in a standby state in both the first network and a second network, the first network supports a PS domain service, and the second network supports a CS domain service. If the UE receives a second IE fed back according to the single-domain registration request by the network device, exiting, by the UE, the standby state in the second network, where the second IE identifies that the first network supports CSFB.

Abstract translation: 本发明公开了一种方法，包括：当用户设备驻留在第一网络上时，由UE向网络设备发送当网络设备对UE执行移动性管理时所需的单域注册请求。 单域注册请求携带第一IE，第一IE识别UE具有CS域语音能力。 UE是单卡双待终端，UE当前处于第一网络和第二网络的待机状态，第一网络支持PS域服务，第二网络支持CS域服务。 如果UE根据网络设备的单域注册请求接收到反馈的第二IE，则由UE退出第二网络中的待机状态，其中第二IE识别出第一网络支持CSFB。
