This paper 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 next generation wireless networks (NGWN). We develop an analytical model for heterogeneous mobile terminals in NGWN. Using a two-class three-RAT heterogeneous wireless network as an example, the effect of using heterogeneous...
Next generation wireless networks (NGWN) will be heterogeneous, comprising a number of radio access technologies (RATs) coexisting in the same geographical area. In NGWN, a joint call admission control (JCAC) algorithm is needed to select the most appropriate RAT for each incoming call. The JCAC algorithm must be user-centric (i.e., consider user preferences in making RAT selection decisions) in order...
