To provide a service continuation from fixed broadband networks to wireless part,new frequencies are allocated to increase the system capacity. Whereas the reuse partitioning is not adapted to those new needs, the multitier cell concept appears to be a good solution. In this study we propose a new bandwidth allocation policy for a multitier cellular network which optimizes bandwidth utilization for customer, denoted MAHCN (Multiservice Allocation in Hierarchical Cellular Networks). Our new protocol consider the service requirement based on two criteria: the mobile speed (low or high) and the type of request (voice or data).
