Managing the complexity of the Information and Communications Technology (ICT) services in smart cities raises a need to use enterprise architecture frameworks to solve the complexity issues. However, the majority of the existing enterprise architecture frameworks have been developed to address the concerns and issues of the stakeholders in their associated world. To address challenges including complexity, multi-stakeholders and the service oriented nature of smart cities, this paper presents an enterprise architecture framework that can be used as a way to manage enterprise architectures in smart cities. This framework focuses on establishing contextual requirements and definitions for smart city systems and services. In contrast to other approaches, in this paper we focus on two important layers, i.e., context layer and service layer, as well as their relationships. The framework is valuable in developing smart services. It also contributes to the understanding of smart city enterprise architectures.
