Active Broadband heads to IMS over DOCSIS
Active Broadband Networks said its service management system now supports the IMS Rx interface as specified in PacketCable 2.0.
The support for the interface paves the way for the delivery of IMS services over DOCSIS networks by providing support for PCMM policy control via the Diameter-based Rx interface, the company explained.
Active Broadband supports PacketCable 2.0 policy control in the company’s Active Resource Manager (ARM) platform, which translates IMS policy control requests into PCMM policy actions in the CMTS.
The ARM also determines network topology using a method the company has devised that it says ensures the accurate identification of the network elements where PacketCable 2.0 services are being delivered.
The ARM’s integrated PCMM policy application manager and policy server component uses this topology information to direct policy control actions to the appropriate CMTS and cable modem.
“A PCMM gate request for a policy control action must be sent to the controlling CMTS for the specified cable modem, but without accurate network topology information, the PCMM policy server won’t know where to send the request,” said Chris Gunner, chief technology officer, Active Broadband Networks. “Our unique solution for accurate and timely topology acquisition enables PCMM policy actions to be directed to the right device, enabling operators to deliver carrier-grade IMS services over DOCSIS.”
