    The SGW acts as a common anchor point during handovers between LTE and Release 8 UMTS networks.
  • ○

    The SGW may provide data plane connectivity between two eNodeBs.
Question 3

Which of the following statements are TRUE regarding the Dynamic PCC rules? (Choose two)

Select all that apply, then click Submit answer.

  • ○

    The Dynamic PCC rules are created on the PCRF and pushed (or pulled) down to the PCEF.
  • ○

    The Dynamic PCC rules are created on the PCEF and pushed (or pulled) down to the PCRF.
  • ○

    When GTP tunnels are used between the SGW and PGW, the Gxc interface is used between the PCRF and the PCEF to carry the dynamic PCC rules.
