Abstract: A network access control method and an apparatus are disclosed. The method includes controlling, by a first network device if determining that a terminal device already establishes a second data connection to a second network, the terminal device to stop establishment of a first data connection to a first network, or controlling the terminal device to end the second data connection, to smoothly establish a first data connection. In this way, it can be ensured that a data connection exists between the terminal device and one network, and it can be ensured that the terminal device can normally transmit data.

Abstract: A detection method, a communication apparatus, and a communication system are provided. The method includes: when a first detection result of a detected QoS flow meets a first trigger condition, detecting the QoS flow based on a first detection execution action corresponding to the first trigger condition, where the first detection execution action includes a detection frequency; and reporting a second detection result detected based on the first detection execution action. In this solution, the first trigger condition is searched for based on the first detection result, next detection of the QoS flow is performed based on the first detection execution action corresponding to the found trigger condition, and the second detection result is reported. Because a detection execution action is determined based on a previous detection result, a detection execution action corresponding to the QoS flow can be accurately determined.

Abstract: This application provides a communication method and a communication apparatus. The method includes: A first core network device obtains a target credential and attribute information of the target credential, and sends the target credential to a terminal device. The first core network device triggers, based on the attribute information of the target credential, the terminal device to perform, by using the target credential, an authentication procedure corresponding to the target credential. According to the communication method provided in this application, the terminal device can learn of a specific authentication procedure that should be performed by using an obtained credential. In other words, according to the method, the terminal device can perform, by using the obtained credential, the authentication procedure corresponding to the credential.
