UpdateLocationInterface defines the Diameter interface for location update. Supported values are SWx and S6a. Defaults to the value of Interface or SWx when the Interface is configured with a value, such as Cx, that does not support location update. UpdateLocationInterface does not enable location update. For this a separate flag parameter UpdateLocation must be set.

Here's an example for Diameter-based EAP-AKA authentication. This parameter is also available with <AuthBy SIMWX> clause.

<AuthBy AKAWX>
    Interface S6a
    UpdateLocation
    # Do location update with SWx instead of S6a
    UpdateLocationInterface SWx
    # Other AuthBy parameters
