A testbed implementation for Service Based Bearer Control in 3GPP2

The policy and charging control function is defined as PCC (policy and charging control) by 3GPP and SBBC (service based bearer control) by 3GPP2. It is valuable to establish an experimental testbed for PCC and SBBC to improve and verify the related performance. At present, we can make use of open source IMS (OSIMS) and UCT PCF to simulate 3GPP PCC, but there is no testbed for the policy control function of SBBC architecture. In this paper, we implement a new SBBC testbed based on 3GPP PCC testbed, whose features show that it is closely in line with the specifications of 3GPP2. Several tests are designed to verify various performances of SBBC. The test results show that our SBBC testbed is effective to be used for researches on QoS controlling in future converged networks.
