Also, as used in this specification and the claims, "and / or" means at least one of the connected objects. For example, A and / or B indicates that it includes three situations: A alone, B alone, and both A and B present.

[0040] In the embodiments of the present disclosure, words such as "exemplary" or "for example" are used to represent by way of example, illustration or explanation. Any embodiment or design form described as "exemplary" or "for example" in the embodiments of the present disclosure should not be construed as being more preferred or advantageous than other embodiments or design forms. Specifically, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0041] Note that the technology described in the embodiments of the present disclosure is not limited to the Long Term Evolution (LTE (registered trademark)) / LTE-Advanced (LTE-A) system, and can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems.

[0135] [Table 1]

[0136] In steps 3 - 4, the UE starts the registration process.

[0137] Optionally, the registration request may be accompanied by indication information that the UE supports the group ID broadcast of the radio access network device.

[0138] In step 5, the network function determines the correspondence between the group ID and the network slice ID corresponding to the UE based on the correspondence between the group ID and the network slice ID, and the Allowed NSSAI of the UE.
