All IP future mobile wireless access network; Passive optical network, dynamic logical macro-cell, and IP multicast

In this paper we propose a dynamic logical macro-cell to support fast, movers in a wireless mobile multimedia access network. The network assumes a micro-cell structure, and uses PON technology for fiber distribution to the radio cells. The broadcast functionality of PON together with IP multicast is used to construct the logical macro-cells. Evaluation of static and dynamic logical macro-cells show that the dynamic macro-cell uses resources efficiently, and relaxes the response time for handovers, at the expense of a slight increase in signaling transactions and IP multicast group updates.
