Tekelec Announces Availability of Softswitch-based MSC Gateway Application; Solution Evolves Mobile Networks with Packet Technology.Business Editors, High Tech Writers MORRISVILLE, N.C.--(BUSINESS WIRE)--March 18, 2002 Tekelec (Nasdaq: TKLC) today announced the availability of the Mobile Switching Center A switching center is a node in a telecommunications Circuit switching network which is connected to either another switching center and/or to end user devices. Switching centers are aware of other centers and possible routes between them such that on demand a center can establish (MSC (1) (MSC.Software Corporation, Santa Ana, CA, www.mscsoftware.com) Founded in 1963 by Richard H. MacNeal and Robert G. Schwendler, MSC is the world's largest provider of mechanical computer aided engineering (MCAE) strategies, simulation software and services. ) Gateway application for its VXi(TM) Media Gateway Controller (MGC MGC Mammalian Gene Collection MGC Media Gateway Controller MGC Middle Georgia College MGC Museums and Galleries Commission (UK government) MGC Mississippi Gaming Commission MGC Manual Gain Control ). The softswitch-based application performs the home location register (HLR (Home Location Register) A database in a cellular system that contains all the subscribers within the provider's home service area. When a subscriber reaches a new service area, the data in the HLR is requested and transferred via SS7 to the VLR (Visitor Location ) look-ups, consolidates PSTN (Public Switched Telephone Network) The worldwide voice telephone network. Once only an analog system, the heart of most telephone networks today is all digital. In the U.S. connectivity, and delivers major call-routing functions typically handled by the MSC switch in mobile networks. Tekelec's application supports both GSM and IS-41 protocols for ANSI (American National Standards Institute, New York, www.ansi.org) A membership organization founded in 1918 that coordinates the development of U.S. voluntary national standards in both the private and public sectors. It is the U.S. member body to ISO and IEC. and ITU (International Telecommunication Union, Geneva, Switzerland, www.itu.ch) A telecommunications standards body that is under the auspices of the United Nations. Comprising more than 185 member countries, the ITU sets standards for global telecom networks. networks. In today's 2G network, a call entering a mobile network can require extensive routing before it can be completed. Each call has to be routed to the recipient's home MSC or gateway MSC, which launches a query to an HLR to determine the MSC serving that subscriber's current location. The call is then routed to the serving MSC, a trip that may traverse multiple switches. With Tekelec's MSC Gateway application, the intelligence is added to a centrally located softswitch, which performs the HLR look-up before the call is routed into the mobile network and then routes the call directly to the serving MSC. "By offloading the query and routing functions from the MSC switch, our softswitch-based application allows mobile carriers to utilize their network resources more efficiently," said Paul Miller, vice president, Packet Telephony, Tekelec. "The MSC Gateway application frees up valuable switch capacity to handle more subscribers and services, streamlines network routing, and creates a foundation for 2.5 and 3G networks." The MSC Gateway application works hand-in-hand with Tekelec's Wireless Tandem application in which a centralized VXi MGC controls an overlay of distributed media gateways (MGs), eliminating the need for point-to-point connections between MSCs. The media gateway performs the IP or ATM conversion under the control of the softswitch. The VXi MGC is the foundation for other packet applications, including international gateway, number portability offload, service bridging, and future 3G features such as MSC server and call session contol function (CSCF CSCF Call Session Control Function CSCF Canadian Ski Coaches Federation CSCF Centre Suisse de Cartographie de la Faune (Neuchâtel, Switzerland) CSCF Call State Control Function (3GPP) ) server.
