Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the various embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions may be omitted for clarity and conciseness.
[0045] The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the present disclosure. Accordingly, it should be apparent to those skilled in the art that the following d...
Embodiment 1
[0070] Figure 4 A Network Slice Specific Authentication and Authorization (NSSAA) procedure in a terminal registration procedure according to an embodiment of the present disclosure is shown. which is, Figure 4 A method of performing an NSSAA procedure in a terminal registration procedure is shown. AMF can store relevant information in UDM according to the result (success or failure) of NSSAA on S-NSSAI.
[0071] refer to Figure 4 , in operation 401, the UE may generate a registration request message. The requested NSSAI to be used by the UE may be included in the registration request message. According to an embodiment of the present disclosure, the requested NSSAI may include one or more S-NSSAIs. For example, the requested NSSAI may include S-NSSAI A and S-NSSAI B.
[0072] According to an embodiment of the present disclosure, the UE may send a registration request message to the AMF via a base station (also referred to as a RAN). In operation 402, the base statio...
Embodiment 2
[0089] Figure 5 A process of determining S-NSSAI for PDN connectivity according to an embodiment of the present disclosure is shown. refer to Figure 5 , when the terminal connects to the Evolved Packet Core (EPC) to request PDN connectivity, the SMF+PGW-C can determine the S-NSSAI for PDN connectivity according to the information received from the UDM+HSS.
[0090]In operation 501, the terminal may send a PDN connectivity request to the MME to establish PDN connectivity. The PDN Connectivity Request message may include Access Point Name (APN) information requested by the terminal. The PDN Connectivity Request message may be sent to the MME via the E-UTRA base station. The name of the message is not limited to the above example.
[0091] In operation 502, the MME that has received the PDN connectivity request message in operation 501 may send a create session request to the S-GW. The name of the message is not limited to the above example.
[0092] In operation 503, the...
