Lucent Technologies and Westell Technologies are joining forces in the name of IP multimedia subsystem (IMS). As part of a newly signed reseller agreement, Lucent is integrating Westell's IMS gateway into its IMS-based solution.

Specifically, Lucent has integrated Westell's converged residential gateways into its IMS service delivery architecture. The goal, according to the companies, is to help enable voice services across cellular and Wi-Fi networks. Initially, the companies will focus their efforts on fixed mobile convergence (FMC), but plan to develop additional IMS-based applications in the future.

The FMC application incorporates Westell's TriLink IMS gateway and the Lucent Feature Server. The TriLink IMS features a built-in ADSL2+ modem and router; a VersaPort2 dedicated Ethernet WAN up-link port that supports emerging access technologies; two integrated SIP VoIP access ports with POTS fallback upon power loss; 802.11g access point for 54 Mbps wireless networking and 4-port Ethernet switch for wired networking; interoperability of 3GPP IMS with multiple carriers and softswitches.

The companies have already completed interoperability testing and have begun to roll out the product commercially. The FMC solution was designed to reduce service providers' capital and operating expenses, the companies said.

"Making Westell's TriLink IMS gateway an integral part of Lucent's industry-leading IMS service delivery architecture creates a more robust and reliable offering for our service provider customers," said Gordon Reichard, Jr., Westell's vice president of marketing. "This ensures interoperability between our customer premises equipment and the IMS core network."

In other Lucent news, the company announced plans to acquire software firm Mobilitec as a way, at least in part, to enhance Lucent’s IMS portfolio.

The mobile content services market is expected to generate $73 billion by 2010, according to the latest research coming out of Pyramid Research. This total will be achieved through a variety of services and applications, including ringtones, games, information, music, video and graphics, the research firm says.
