The focus of this work is on the definition of a network architecture allowing wireless users to access the fixed network and Intelligent Network (IN) services via a DECT air interface. After motivating the choice of the DECT air interface, the general architecture is discussed in detail, with the aim of keeping a short term perspective, i.e. limiting the impact of the deployment of the wireless access on the existing network architecture and protocols. As an example, the paper focuses on the provision of a Virtual Private Network service, by discussing the exchange of signalling messages relevant to key procedures.
