If a terminal device is registered on multiple networks through multiple access technologies, then the service progress is improved, but the slice information may become mutually exclusive causing conflicts
Solution Approach 1:
The terminal device performs registration procedures in advance on multiple networks through different access technologies (3GPP and non-3GPP) before actual service execution. This preliminary registration ensures that slice information is acquired and configured beforehand, allowing the device to switch between networks seamlessly without service interruption, thus improving service progress while maintaining slice information consistency through pre-established registration states
Solution Approach 2:
The patent introduces a registration management mechanism that acts as an intermediary between multiple networks and the terminal device. This mechanism coordinates the registration processes across different access technologies, ensuring that slice information from 3GPP and non-3GPP networks is harmonized and non-exclusive. The intermediary manages the interaction between multiple networks, preventing conflicts while enabling simultaneous service progress

AI summary
The embodiments of the application disclose a registration method, a terminal device and a network device. The method includes: when the terminal device is registered on a first network through a first access technology, acquiring, by the terminal device, first slice information; when the terminal device is registered on a second network through a second access technology, acquiring, by the terminal device, second slice information, where the second slice information and the first slice information are not mutually exclusive. The method, terminal device and network device of the embodiments of the present application can ensure that slices obtained by the terminal device over multiple access technologies are not mutually exclusive, thereby ensuring the progress of services.
