Active Broadband Bridges Gap Between IMS and DOCSIS Networks

By Anuradha Shukla, TMCnet Contributor

Active Broadband Networks is facilitating the delivery of IMS services over DOCSIS networks through its Active Resource Manager that supports the IMS Rx interface as specified in PacketCable 2.0.

As the broadband service management solutions provider supports PacketCable 2.0 policy control in the company’s Active Resource Manager (ARM (News - Alert)) platform, IMS policy control requests are easily translated into PCMM policy actions in the CMTS.

Its ARM uses a unique method to determine network topology. This method is said to ensure the accurate identification of the network elements where PacketCable 2.0 services are being delivered.

By using this topology information, the ARM's integrated PCMM policy application manager and policy server component can accurately direct policy control actions to the right CMTS and cable modem.

Traditionally, a PCMM gate request for a policy control action has to be sent to the controlling CMTS for the specified cable modem. However, the PCMM policy server does not know where to send the request in the absence of accurate network topology information.

"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," said Chris Gunner, chief technology officer, Active Broadband Networks.

Active Broadband Networks supplies broadband service management solutions, and helps broadband service providers to manage and monetize growth in the consumption of residential broadband Internet.

In March this year the company demonstrated how its Dynamic Broadband Service Manager (DBSM) can be used to deliver third-party subsidized services.

The demonstration was done at the CableLabs (News - Alert) Winter Conference, and during this event Active Broadband demonstrated how the DBSM can be used to facilitate transactions between content providers and subscribers.

DBSM allows the content providers to transact for broadband services on behalf of subscribers without violating any regulatory requirements.
