This paper analyzes the impact of the fast-growing BYOD (Bring Your Own Device) trend in the corporate mobile market, which blurs lines between business and personal usage. To enable selective funding and resource optimization for BYOD, we propose that the enterprise determines its own service delivery policy, using an enterprise Business Context (eBC) Policy tool. The enterprise is best placed to ascertain session context and priorities from its internal context sources, kept only by the enterprise, to retain privacy. While NETWOK policies are controlled by network operators, the enterprise could and should determine the SESSION policies that are based on its business goals. The eBC policy can be further utilized for optimizing resource usage and influencing employee consumption. The enterprise goals need to be translated into standard policy rules and conveyed to the carriers via existing 3GPP standards, to fit in with existing networks. This is paper raises several new ideas which are further researched in follow-on papers.
