About Roaming Profiles

Roaming Profiles are used in conjunction with the S9 interface. The S9 interface allows the PCRF to support LTE roaming services such as Voice over LTE. This is done be establishing S9 and Rx sessions between the Home PCRF (H-PCRF) and the Visiting PCRF (V-PCRF).

Roaming Profiles are used to allow or disallow S9 requests at the H-PCRF, and to validate messages coming from the H-PCRF and going to the V-PCRF. A V-PCRF also uses the roaming profile to decide whether to report UE Time zone and location information to the H-PCRF. You can define up to 50 profiles, each with different parameters.

S9 interface functionality must be turned on before roaming profiles can be used. By default, the PCRF cannot initiate or accept S9 requests. To turn initiate or accept on, modify the S9 settings using the Policy Server tab in the Policy Server configuration. If an MRA is deployed in the network, the primary and secondary DEA (or S9 peer) can be configured using the MRA tab located in the MRA configuration.

Note: At least one MRA Diameter Routing Peer must be defined to configure the primary/secondary DEA.
