Tiivistelmä
Current mobile phones are considered as multipurpose and powerful handheld devices suitable for many activities. This thesis is analyzing the oldest, and still the most important, functionality of a mobile phone; telephony communication. The specific topic is how the traditional and rather stable peripheral, like a cellular modem processor, is integrated to the latest open source application environments. In these environments legacy functionality meets the open source as a newcomer, and it may create some interesting solutions for an open source community, business partners and the industry overall. Traditionally the mobile phone, and especially the modem development, has been a closed source and proprietary design; it can be assumed that open source environments are enforcing different business scenarios even for a traditionally closed sourced modem development and co-operation. This thesis includes two white papers to propose a more efficient software architecture for the modem integration that could be standardized with and complement an open source implementation. The conclusion of this thesis contains some of the questions found during standardization discussions; what kinds of problems and challenges there are when initiating a standardization for some technology area.
