TTPCom has outlined its strategy for its mobile handset technology, its TTPCom architecture.

The firm said the architecture provides a common software platform approach across multiple chipsets and multiple access technologies, allowing large technology blocks to be included or omitted for a variety of different handset models.

The architecture has been specified for a different access technologies, including traditional cellular (such as GSM/GPRS and WCDMA) as well as emerging capabilities such as WiFi, WiMax and Digital TV, said the firm.

TTPCom added that the architecture ensures a clean separation of access technologies from IP transport protocols, leading to reliable implementations and reduced handset testing cycles.

The industry transition to IP Multimedia Subsystem (IMS) is particularly exciting for the firm. “IMS completes the transition from a circuit switched network to a fully packet based network. This change enables a range of advanced new services to be delivered to handset subscribers,” said TTPCom.

“Convergence means uncertainty, change and disruption for handset manufacturers,” said Peter Whale, head of software product strategy at TTPCom. “True converged devices can now be for everyone, no longer the preserve of smartphone users”

The trend of including multiple stacks and multiple applications increases handset complexity. Operators are moving from legacy circuit switched networks to full packet based services, although the move will take five to ten years. However, operators are doing this in different ways, which will create an even more fragmented and complex market, said TTPCom.

The firm said it’s architecture for converged devices supports the following standards: IP Multimedia Subsystem (IMS); DVB-H; Bluetooth; WiFi (802.11x); GAN/UMA; A-GPS; FM Radio.
