Network slice selection based on requested service

A device, comprising:

• one or more memories;
• and
• one or more processors, communicatively coupled to the one or more memories, to:
• receive, from a user equipment, single-network slice selection assistance information (S-NSSAI),
• wherein the S-NSSAI is associated with a network,
• determine a resource sharing configuration (RSC) associated with the S-NSSAI;
• identify a slice/service type (SST) of the S-NSSAI;
• identify, based on identifying the SST, a network slice instance (NSI) table associated with the SST;
• determine whether the RSC associated with the S-NSSAI is included in the NSI table;
• determine, based on determining that the RSC associated with the S-NSSAI is included in the NSI table, whether the S-NSSAI is associated with a first network slice instance (NSI) of the network;
• and
• when the S-NSSAI is determined to be associated with the first NSI,
• map the S-NSSAI to the first NSI to permit the user equipment to communicate via the first NSI using a protocol data unit (PDU) session associated with the S-NSSAI, or
• when the S-NSSAI is not determined to be associated with the first NSI,
• form a second NSI of the network according to the RSC associated with the S-NSSAI, and
• map the S-NSSAI to the second NSI to permit the user equipment to communicate via the second NSI using a PDU session associated with the S-NSSAI.

A non-transitory computer-readable medium storing instructions, the instructions comprising:

• one or more instructions that, when executed by one or more processors, cause the one or more processors to:
• receive, from a user equipment, single-network slice selection assistance information (S-NSSAI),
• wherein the S-NSSAI is associated with a network,
• determine a resource sharing configuration (RSC) associated with the S-NSSAI;
• identify a slice/service type (SST) of the S-NSSAI;
• identify, based on identifying the SST, a network slice instance (NSI) table associated with the SST;
• determine whether the RSC associated with the S-NSSAI is included in the NSI table;
• determine, based on determining that the RSC associated with the S-NSSAI is included in the NSI table, whether the S-NSSAI is associated with a first network slice instance (NSI) of the network;
• and
• when the S-NSSAI is determined to be associated with the first NSI,
• map the S-NSSAI to the first NSI to permit the user equipment to communicate via the first NSI using a protocol data unit (PDU) session associated with the S-NSSAI, or
• when the S-NSSAI is not determined to be associated with the first NSI,
• form a second NSI of the network according to the RSC associated with the S-NSSAI, and
• map the S-NSSAI to the second NSI to permit the user equipment to communicate via the second NSI using a PDU session associated with the S-NSSAI.
