Sonus Networks Supports IMS Architecture

Sonus Networks unveiled its solution for an IP Multimedia Subsystem (IMS) architecture, leveraging its existing products: the GSX family, PSX, SGX, ASX and Insight Management Systems. The company said the IMS architecture substantially mirrors the Sonus-built networks currently deployed. Essential to an IMS deployment is the ability for elements within the network to communicate with each other using SIP -- which Sonus already supports.


Sonus said its IMS solutions enable service providers to deliver integrated services over mobile, WiFi and wireline networks providing service differentiation and reduced time-to-market. Further, wireless operators can implement Sonus' proven Gateway Mobile Switching Center (GMSC) solution in their 2G and 2.5G networks today and seamlessly migrate to an IMS-compliant wireless voice network in the future. Sonus' wireless solutions deliver the features and protocol support necessary for rapid deployment in GSM, CDMA, TDMA and 3G wireless network environments.


Sonus also introduced the SRX and HSX products to its IMS product family. The SRX provides streamlined multimedia capabilities when customers choose to deploy a discrete Serving-Call Server Control Function (S-CSCF), creating a central coordination point for all SIP sessions. Leveraging the functionality already available today, Sonus will be offering the SRX as a separate software product in the fourth quarter of 2005 to allow for further architectural flexibility. The HSX is an evolution of Sonus' centralized subscriber management capabilities that enables service providers to deliver device independent multimedia services. The HSX Home Subscriber Server (HSS) will also be available in the fourth quarter of 2005. http://www.sonusnet.com
