Use of Binding Indication Between Network Functions for Sharing Resource Redundancy Information Concerning Network Function Service Instances

A method performed by a computer-implemented apparatus configured to implement a first network function, the method comprising:

• transmitting, from the first network function, to a second network function, a first message including a first parameter indicating no-redundancy to indicate that a first context is exclusively bound to a specific Network Function (NF) service instance within the first network function;
• and
• wherein the specific NF service instance is identified in a binding indication included in the first message.

A method performed by a computer-implemented apparatus configured to implement a second network function, the method comprising:

• receiving, at the second network function, from a first network function, a first message including a first parameter indicating no-redundancy to indicate that a first context is exclusively bound to a specific Network Function (NF) service instance within the first network function;
• wherein the specific NF service instance is identified in a binding indication included in the first message.
