2.5G is a relatively inexpensive mobile data communication service. Vodafone was concerned that its extensive revenues from text messaging could be cannibalised by email carried on 2.5G at a fraction of the price, and that the 2.5G solutions lacked functionality to support innovative m-commerce propositions. David identified the actions required to complete end to end design to support business needs, and an opportunity for Vodafone become the ‘partner of choice’ for service providers to help create a healthy m-commerce industry by augmenting basic data services with valuable billing and other capabilities to support mobile internet service providers.
David helped Vodafone validate that GPRS planning covered all the areas that were required for a successful launch. David led and documented a series of workshops, defining a number of issues and risks within these plans and recommended mitigating actions. The areas covered included high level system design and elements like roaming, network management, customer care, provisioning and billing.
Among the gaps, the workshops identified a potential need for a node or sub-system between the GGSN and systems outside Vodafone’s network, to provide controlled interfaces to third parties, generate records for billing by detecting events and determining content and provide mobile station search/directory services for host applications.
David led a small team to gather business requirements for this ‘service access node’. These requirements included the changes required to enable Vodafone to establish itself as the mobile network ‘partner of choice’ in the then nascent m-commerce space. David and his team identified potential solutions to enable Vodafone to determine a long term solution.
