The document discusses the evolution of mobile data service architectures from 2G/3G/4G to a next-generation architecture. It proposes a new architecture with a flattened network structure and optimized, integrated system design. The new architecture features an open management interface, separated control and data planes, and extensibility to support future transactions per second needs. It aims to provide a multi-service environment with in-line services, subscriber management, and flexible virtualization capabilities.
