Failure retry order in response to a network function discovery request

A method for telecommunication, comprising:

• sending, by a consumer network node of a wireless communication network, a discovery request to a network repository function (NRF) to identify a producer network node capable of providing a service to the consumer network node,
• wherein the discovery request identifies one or more parameters specified by the consumer network node, wherein the one or more parameters include at least one of:
• information of a service requested by the consumer network node, locality information associated with the consumer network node, or network slice information associated with the consumer network node;
• and
• receiving, by the consumer network node, information about a list of producer network nodes capable of providing the service to the consumer network node with a retry order specifying an order of the producer network nodes for retrying a service request upon a failure of an initial service request,
• wherein the order of the producer network nodes is determined based on at least a latency associated with each of the producer network nodes,
• wherein the list of the producer network nodes further includes network node group information and retry order group information associated with the producer network nodes,
• wherein the producer network nodes are divided into network node groups based at least on the latency associated with each of the producer network nodes, and
• wherein the retry order group information identifies a retry order including at least one producer network node to retry the service request upon a failure of the initial service request.

A system for retrying a request for service, the system comprising:

• at least one hardware processor;
• and
• at least one non-transitory memory storing instructions, which, when executed by the at least one hardware processor, cause the system to:
• send, by a consumer network node of the system, a discovery request to a network repository function (NRF) to identify a producer network node capable of providing a service to the consumer network node,
• wherein the discovery request identifies one or more parameters specified by the consumer network node, wherein the one or more parameters include at least one of:
• information of the service requested by the consumer network node, locality information associated with the consumer network node, or network slice information associated with the consumer network node;
• cause the NRF to:
• identify producer network nodes capable of providing the service to the consumer network node;
• and
• send information about a list of producer network nodes capable of providing the service to the consumer network node with a retry order specifying an order of the producer network nodes for retrying a service request upon a failure of an initial service request,
• wherein the order of the producer network nodes is determined based on at least a latency associated with each of the producer network nodes;
• and
• send, by the consumer network node, the initial service request to a producer network node identified in the list of producer network nodes;
• and
• upon failure of the initial service request, send, by the consumer network node, another service request to another producer network node based on the retry order,
• wherein the list of the producer network nodes further includes network node group information and retry order group information associated with the producer network nodes,
• wherein the producer network nodes are divided into network node groups based at least on the latency associated with each of the producer network nodes, and
• wherein the retry order group information identifies a retry order including at least one producer network node to retry the service request upon a failure of the initial service request.
