AI Technical Summary
Technical Problem
When a network slice deployed on the core network is congested or unavailable, how to increase the success rate of user equipment in idle or inactivated states for network slice service requests?
Method used
By sending network slice and network slice access layer group (NSAG) information, the terminal device can perform cell reselect and/or random access to improve the success rate of service requests.
Benefits of technology
This method helps the terminal device successfully reselect or randomly access the supported network slice when the network slice is unavailable, thereby improving the success rate of service requests and the accuracy of the access network device in the rapid identification of services.

Abstract
The invention discloses a communication method and device. In the method, a first network device determines that a first network slice is unavailable and sends a mapping relationship between the first network slice and a second network slice and first NSAG information to a terminal device, the first network slice belongs to a network slice allowed by the terminal device, and the second network slice is a network slice replacing the first network slice. The first NSAG information does not comprise NSAG information associated with the first network slice. Since the first NSAG information does not include the NSAG information associated with the first network slice, when the terminal equipment executes cell reselection, the terminal equipment does not reselect a cell only supporting the first network slice, and the success rate of initiating a slice service request after executing cell reselection based on the network slice by the terminal equipment is improved; alternatively, the method helps to improve the accuracy of the access network device to quickly identify the service of the terminal device when the terminal device executes the random access based on the network slice.
