UP VTIME feature support

RoadRunnr opened this issue · comments

We currently use a timer in the PFCP code to support quota validity times. With Rel.16.4 a new UP feature was introduced to handle this in the UP.

Making use of this feature clears another obstacle on the path to a stateless ergw.

VTIME is optional in the UP, the C-Node therefore needs a fallback. The existing timer server support from exp/stateless branch (once it is sufficiently stable) should be used a basis. Then the support for optionally pushing the timer into the URRs needs to be added.
