Call admission control is an essential approach for traffic control and QoS provisioning. Compared with the single network, it is quite complicate for multi-service heterogeneous wireless networks. In this paper, a hierarchical joint call admission control HJCAC is proposed. The framework of the scheme, new introduced messages format and service access procedure is also designed in this paper. Simulation results proved that the proposed mechanism can enhance the acceptance ratio and select the most appropriate network for incoming services.
