1. An apparatus comprising:
at least one processor; and
at least one memory including computer program code;
the at least one memory and the computer program code being configured to, with the at least one processor, cause the apparatus at least to perform:
receive, from a first network entity associated with a first domain in a communication network, a request to communicate;
determine a second network entity to which to send the request;
determine that the second network entity is associated with a second domain in the communication network; and
enforce at least one access policy for routing the request to the second network entity;
wherein the apparatus is a first service communication proxy trusted in both the first and second domains; and
wherein the determination of the second network entity, and the determination that the second network entity is associated with the second domain, comprise causing the apparatus to perform:
send a discovery request to a registration entity in the communication network;
receive a response to the discovery request, the response comprising one or several candidate second network entities and for each candidate second network entity an indication of the second domain; and
use the response to determine the second network entity out of the one or several candidate second network entities and that the second network entity is associated with the second domain.
