The heterogeneous networks are the Next Generation Wireless Networks (NWGN).The presence of heterogeneous networks leads to the necessity of multi-mode terminals i.e. single mode, dual mode, triple mode, quad-mode etc. based on number of RATs in the heterogeneous networks which results in varying mobile capability. The main problem with the heterogeneous networks is the unfairness in allocation of radio resources. In the same heterogeneous network single-mode terminals (Low-capability mobile terminals) experience high blocking probability compared to quad-mode terminals (High-capability mobile terminals) in the same network. To reduce this problem of unfair allocation of radio resources a Terminal Modality Based Joint Call Admission Control (TJCAC) Algorithm has been proposed. In this proposed algorithm the call admission decisions take into account modality (capability) of the mobile terminal, Load on each RAT and Terminal Support Index of each RAT during resource allocation. We have proposed an analytical model to evaluate the performance of the algorithm and show that there is a decrease in the call blocking and dropping probabilities.
