Effect of Mobile Terminal Heterogeneity on Call Blocking/dropping Probability in Cooperative Heterogeneous Cellular Networks
It is envisaged that Next Generation Wireless Networks (NGWN) will be heterogeneous, consisting of multiple Radio Access Technologies (RATs) coexisting in the same geographical area. In these heterogeneous wireless networks, mobile terminals of different capabilities (heterogeneous terminals) will be used by subscribers to access network services. The authors investigate the effect of using heterogeneous mobile terminals (e.g. single-mode, dual-mode, triple-mode, etc.) on call blocking and call dropping probabilities in cooperative heterogeneous wireless networks. They develop analytical models for heterogeneous mobile terminals and joint radio resource management in heterogeneous wireless networks. Using a two-class three-RAT heterogeneous wireless network as an example, the effect of using heterogeneous terminals in the network is evaluated.
