Intelligent Approach to Deploying IMS Solutions
The rise of mobile multimedia communications is driving fixed and mobile service providers to migrate their legacy and Voice over IP (VoIP) networks to an IMS-based architecture. IMS provides an IP-based framework for multimedia sessions and services and enables LTE networks to handle voice calls, known as Voice over LTE (VoLTE). Dialogic delivers an intelligent, efficient path to IMS migration through its IMS-ready, IP-based products and Diameter-based solutions.
Dialogic products help service providers transition seamlessly from legacy networks to IMS through circuit-to-IP call control transformation, enhanced media capabilities and new Diameter services.
Circuit-to-IP Call Control Transformation
Most service providers have already begun to migrate from circuit-switched to packet-switched networks. Further transformation is required for packet-based networks to align with IMS by adding functionality in the session control layer. The ControlSwitch System is a Next-Generation Network (NGN) softswitch that seamlessly transitions to serve as the MGCF and BGCF in an IMS network. Service providers have deployed the ControlSwitch System to replace their older Class 4 switching technology with a field-proven IMS-ready solution.
Similarly, the BorderNet Session Border Controller provides P-CSCF and IBCF in a compact 1U platform and can also be deployed as a virtualized appliance to support NFV applications.
Enriched Media Capabilities
Multimedia services are at the heart of IMS, with media interworking playing a key role in IMS deployments. I-Gate 4000 PRO and EDGE Media Gateways can help service providers transition to an IMS network by acting as the IMS GW, MGW or SGW, and provide network functions such as IP-to-IP media transcoding, media optimization, RFC 4117 support and SIP/H.248 signaling. With their open architecture, I-Gate 4000 PRO/EDGE MGWs can interwork with existing MGCF deployments from other vendors or in conjunction with the ControlSwitch System MGCF/BGCF to take advantage of the geographical redundancy and high reliability of the Dialogic offerings.
PowerMedia XMS is a powerful media server that can fulfill the joint roles of MRF and MRB in an IMS network. PowerMedia XMS features advanced multimedia capabilities including support for the Opus audio codec, VP8 video codec and HTML5 browsers, enabling it to also serve as a media gateway between IMS and Web Real-Time Communication (WebRTC) networks. PowerMedia XMS supports the Media Server Markup Language (MSML) interfaces (RFC 5707) for multimedia control in an IMS network.
Next Steps on Your Path to IMS
The Long-Term Evolution network of tomorrow may seem a long way from where your network is today, but Dialogic can help you reach that goal more quickly and more efficiently with solutions to position you to get the most out of your IMS deployment strategy.
