  Ubiquitous information service converged by different types of heterogeneous
networks is one of fundamental functions for smart cities. Considering the
deployment of 5G ultra-dense wireless networks, the 5G converged cell-less
communication networks are proposed to support mobile terminals in smart
cities. To break obstacles of heterogeneous wireless networks, the 5G converged
cell-less communication network is vertically converged in different tiers of
heterogeneous wireless networks and horizontally converged in celled
architectures of base stations/access points. Moreover, the software defined
network controllers are configured to manage the traffic scheduling and
resource allocation in 5G converged cell-less communication networks.
Simulation results indicate the coverage probability and the energy saving at
both base stations and mobile terminals are improved by the cooperative
grouping scheme in 5G converged cell-less communication networks.
