  • Steering of roaming for 5G core roaming in an internet packet exchange network
    Patent number: 10834571
    Abstract: A system and method for implementing Steering of Roaming for 5G core roaming in an Internet Packet Exchange (IPX) network. A Hypertext Transfer Protocol (HTTP)/2 Proxy is deployed in an IPX network. The HTTP/2 Proxy receives N32-f request message from a Visited Public Land Mobile Network (VPLMN). The N32-f request has an embedded N12 authorization request message or an embedded N8 registration request message. If VPLMN is a non-preferred roaming partner, the HTTP/2 Proxy appends a patch-request to N32-f request message and routes it to the Home Public Land Mobile Network (HPLMN). The patch-request causes the home Security Edge Protection Proxy (hSEPP) to replace Mobile Country Code (MCC) or Mobile Network Code (MNC) value with a predefined value that will trigger a rejection from HPLMN. The mobile device will select another VPLMN. If the VPLMN is a preferred roaming partner, the HTTP/2 Proxy routes the request without appending a patch-request.
