PDS - Wireless

NCS 2 is a wireless convergence system based on 3GPP release 6
specification with supplementary services and full interoperability to UMTS, GSM, PSTN and WLAN based on UMA and compliant to 3GPP interoperability specification. Our FMC solution is based on 3GGP Rel 5 and Rel 6 specifications with other standards to support QOS, Media signaling and HSS. NCS2 is based on LINUX and can interoperate with differentiated networks to provide ubiquitous and seamless service. It can be a single system or a distributed subsystem based on the scalability and management needs. NCS2 has interface to application servers through OSA interface and ISC interface, which can provide the application server capability to non 3GPP networks like GSM, WLAN networks. NCS2 can connect to non 3GPP networks through native protocols and management entities

NCS-2 has the capability to hold multiple applications in its application container and makes the application utility visible to multiple networks. NCS2 UMTS R99, R4, R5 compliant and 3GPP Core Network Release 5 and Release 6 specifications compliant.

NCS-2 has the following elements

	CSCF (proxy Interrogating and serving)
	Policy engine (Go and Gq interface with PEP and PDF)
	Media signaling interface (MRFC, MG)
	Wireless access Switch (WAG, PDG and OCS interface for 802.xx systems)
	OSA interface (OSA Parlay API container)
	Interface to HLR, VLR (CAP and MAP interface) (Camel versions and MAP versions can be selected based on requirements)
	BGCF interface
	Signaling gateway interface
	Home Subscriber subsystem
	IM SSF and GSM SCF (CAP and MAP interface)
	BGCF, MGCF, MRFC, SLF interface, ALG, STUN Gateway and
	WAG, PDG with 3GPP AAA server and AAA proxy

We support the following reference points

	Cx	Reference Point between a CSCF and an HSS
	Dx	Reference Point between an I‑CSCF and an SLF
	Gi	Reference point between GPRS and an external packet data network
	Gm	Reference Point between a UE and a P-CSCF
	ISC	Reference Point between a CSCF and an Application Server
	Iu	Interface between the RNS and the core network. It is also considered as a reference point
	Ix	Reference Point between IMS ALG and NA(P)T-PT
	Le	Reference Point between an AS and a GMLC
	Mb	Reference Point to IPv6 network services
	Mg	Reference Point between an MGCF and a CSCF
	Mi	Reference Point between a CSCF and a BGCF
	Mj	Reference Point between a BGCF and an MGCF
	Mk	Reference Point between a BGCF and another BGCF
	Mm	Reference Point between a CSCF and an IP multimedia network
	Mr	Reference Point between an CSCF and an MRFC
	Mw	Reference Point between a CSCF and another CSCF
	Mx	Reference Point between a CSCF and IMS ALG
	Sh	Reference Point between an AS (SIP‑AS or OSA‑CSCF) and an HSS
	Si	Reference Point between an IM-SSF and an HSS
	Ut	Reference Point between UE and an Application Server
	Go.Gq	PEP PDF interface and Application function and PDF interface

NCS-2 supports various multimedia application services such as Push to talk, Voice messaging, active directory service, and send voice, video chat, and multimedia chat, IP mobile-TV.

NCS 2 also provides full access to Wireless lan-based network and for 802.xx based radio technologies. NCS2 can integrate 802.11a, 802.16 into UMTS network for session-based handover, device interchange, multi-radio device handover.

NCS2 can provide unified application access and interoperability between WLAN and UMTS – IMS network. It allows subscriber to roam/choose across WLAN and UMTS network for application and basic call services.

NCS2 come with WAG and PDG server with full support of PEP and PDF.

NCS-2 Wireless Lan interface

WAG and PDF with NCS 2 is fully complaint with 3GPP specification TS. 23.234. It is fully compliant with UMA based UNC specifications for seamless handover and radio control.

NCS2 Supports multiple network to provide ubiquitous application service and multimedia interoperability with Full SLA to QOS.
