Abstract: A communication method and apparatus In response to an AMF device determining whether a first tracking area where a first access network device currently accessed by a terminal is located does not support a first network slice requested by the terminal and in response to the first tracking area does not support the first network slice, the AMF device sends second radio resource information to the first access network device. The second radio resource information is usable at the first access network node to determine frequency band information, and the frequency band information is usable at the terminal to access the first network slice in a second tracking area by using a target access network device, the second tracking area where the target access network device is located supports the first network slice. In this case, the terminal accesses the first network slice that the terminal requests to access.

Abstract: Embodiments of this application provide a slice information processing method and apparatus to preferentially allocate a network slice resource to a slice for which a slice service level agreement SLA has been signed. An example solution includes: An access network device determines that a slice service level agreement (SLA) has been signed for a first slice and that no slice SLA has been signed for a second slice. The access network device prioritizes a user behavior action of the first slice, or deprioritizes a user behavior action of the second slice.

Abstract: This application provides a network verification method and apparatus. The method may include: A slice statistics network element (30) receives a slice registration request message (410) from a mobility management network element (20), where the slice registration request message (410) includes an identifier of a terminal device (10) and an identifier of a network slice. In response to the slice registration request message (410), the slice statistics network element (30) determines whether the terminal device (10) occupies a resource of the network slice. The slice statistics network element (30) determines, based on a determining result, whether to count the terminal device (10) into statistics about a terminal accessing the network slice.
