Application Development
Fixed Network
Fixed Network development, our consultants have recently been involved with the softswitch development for
a major UK Network upgrade. The network is based on current standards specifications (e.g. ITU-T and UK NICC)
for SIP-I networking and TISPAN specifications for AGW, BGW, TGW and MS control via H.248.
Working with Requirements Capture, Systems Management through to Integration and Verification; our consultants,
many with an impressive background in protocols e.g. ISUP, SS7, SIP, H.248 etc. made an invaluable contribution to
the project; including the migration from circuit switching to packet switching and handling the interface with
legacy systems.

Our knowledge and experience in Wireless network systems covering GSM and 3G, includes projects for a major
network infrastructure supplier for major UK and global Mobile Operators. Our experience working with Feasibility
studies, development and test has included projects involving HLR, MSC and BSC nodes, working with 3GPP specifications
and signalling protocols ISUP, MAP and BSSAP.
