Abstract :
The convergence of radio access technologies with all-IP core network has gained significant attention recently. Through the all-IP based policy and charging control (PCC) architecture standardized in 3GPP R8, the charging rules are consistent with application-level and IP-level policy control. It is essential to investigate the signaling overhead incurred by PCC and the OCS management during the mid-session events, such as the handover and QoS changes. To address this issue, this paper investigates PCC and OCS traffic rate over LTE networks.
