Abstract: There is provided an apparatus comprising at least one processor and at least one memory including a computer program code, the at least one memory and computer program code configured to, with the at least one processor, cause the apparatus at least to: receive, at a first network repository function in a first network from a security edge protection proxy in a second network, a request for discovering one or more roaming hubs and/or security edge protection proxies in the first network; and send, from the first network repository function to the security edge protection proxy in the second network, a response comprising information identifying the one or more roaming hubs and/or security edge protection proxies in the first network and information identifying one or more further networks which can be reached via a respective roaming hub and/or security edge protection proxy in the first network.

Abstract: Systems, methods, and software for inter-PLMN communications. In one embodiment, a roaming hub receives a message from a sending entity across an N32 interface, and determines whether the message includes an HTTP custom header that indicates a PLMN that is validated. When the message as received does not include the HTTP custom header, the roaming hub adds the HTTP custom header to the message that indicates the PLMN of the sending entity, integrity protects the HTTP custom header, and forwards the message toward a receiving entity.
