Network architecture for unified handling of services

Abstract

Embodiments herein disclose a modular, scalable, and flexible network architecture which can handle all services in a unified manner, wherein the architecture can handle built-in services in NGNs in a manner similar to application-based services by decoupling the 'built-in' service handling from “network control plane” of the networks. Embodiments herein disclose the modular, scalable, and flexible network architecture, wherein the network treats all types of signaling messages as payload or data or service, and the architecture thereof. Embodiments herein disclose the modular, scalable, and flexible network architecture, wherein built-in services (such as, but not limited to, session establishment, registration (network attachment), mobility, authentication, and so on) are moved out of the control plane and as a part of the service/application plane.
