Support of indirect communication with TLS

A method performed by a Service Communication Proxy, SCP, for indirect communication in a core network of a wireless communication system with Transport Layer Security, TLS, the method comprising:

• receiving, from a Network Function, NF, service consumer, a Hypertext Transfer Protocol, HTTP, message that is intended for a first NF service producer instance, the HTTP message using a Fully Qualified Domain Name, FQDN, of the SCP and having a path that includes a query parameter set to a first value of the first NF service producer instance;
• obtaining an HTTP response for the HTTP message;
• and
• sending the HTTP response to the NR service consumer.

A network node that implements a Service Communication Proxy, SCP, for indirect communication in a core network of a wireless communication system with Transport Layer Security, TLS, the network node adapted to:

• receive, from a Network Function, NF, service consumer, a Hypertext Transfer Protocol, HTTP, message that is intended for a first NF service producer instance, the HTTP message using a Fully Qualified Domain Name, FQDN, of the SCP and having a path that includes a query parameter set to a first value of the first NF service producer instance;
• obtain an HTTP response for the HTTP message;
• and
• send the HTTP response to the NR service consumer.
