Abstract

Providing Roaming Value Added Service (RVAS) network function for Home Public Land Mobile Network (HPLMN) is disclosed herein. In some embodiments, a Home Network Repository Function (H-NRF) in an HPLMN of a telecommunications network obtains information about a Home Control Network Function (NF) and a Roaming Control NF. A Visited NF in a Visited Public Land Mobile Network (VPLMN) sends a discovery request to the H-NRF in the HPLMN. The H-NRF receives the discovery request from the Visited NF in the VPLMN, and determines that, for the discovery request and the VPLMN, RVAS is applicable. The H-NRF selects the Roaming Control NF and the Home Control NF for the discovery request, and transmits, to the Visited NF, a response to the discovery request, the response comprising an address of the selected Roaming Control NF instead of an address of the selected Home Control NF.
