System and method for access token validation at a network repository function

A method for token validation at a network repository function (NRF), the method comprising:

• receiving, by a processor associated with a system, a token from one or more users via a computing device wherein the token is based on a network function (NF) request generated by the one or more users;
• decoding, by the processor, the token received from the one or more users and determining if the decoded token is valid;
• in response to a positive determination, sending, by the processor (202), the decoded token to a resource server within a predetermined period;
• receiving, by the processor, a token validation request from the resource server within the predetermined time;
• and
• generating, by the processor, one or more requested services for the one or more users via the resource server within the predetermined period.

A user equipment (UE) for sending tokens, the UE comprising:

• one or more processors communicatively coupled to a processor associated with a system, wherein the one or more processors are coupled with a memory, and wherein said memory stores instructions which, when executed by the one or more processors, cause the one or more processors to:
• transmit a token to the processor via a network, wherein the token is based on a network function (NF) request generated by the one or more users
• wherein the processor is configured to:
• receive the token from the UE;
• decode the token and determine if the decoded token is valid;
• in response to a positive determination, send the decoded token to a resource server within a predetermined period;
• receive a token validation request from the resource server within the predetermined period;
• and
• generate one or more requested services for the UE via the resource server within the predetermined period.

A non-transitory computer readable medium comprising a processor with executable instructions, causing the processor to:

• receive a token from one or more users via a computing device wherein the token is based on a network function (NF) request generated by the one or more users;
• decode the token received from the one or more users and determine if the decoded token is valid;
• in response to a positive determination, send the decoded token to a resource server within a predetermined period;
• receive a token validation request within the predetermined time from the resource server;
• and
• generate one or more requested services for the one or more users via the resource server within the predetermined period.
