Abstract: Disclosed is a system and method for channel allocation in a multi-band wireless network. The system includes microcell base stations, at least one macrocell base station, a mobile station, and a channel allocation center. When the mobile station makes/receives a call or executes a handover, the channel allocation center uses repacking on demand (RoD) scheme to allocate a radio channel of either a macrocell base station or a microcell base station to the mobile station. RoD has the following steps. First, a microcell channel is trying to be allocated if available. If no microcell channel is available, a macrocell channel is then trying to be allocated. Third, if no macrocell channel is available, repacking is performed to execute a handover of another mobile station's call from the macrocell to another microcell, and to allocate a reclaimed macrocell channel to the mobile station. Otherwise, no repacking call is available and the mobile station is blocked or forced terminated. By the invention, call blocking probability and call handover rate of the mobile stations in the multi-band wireless network can be reduced, and thus users' satisfaction can be enhanced.

Abstract translation: 公开了一种用于多频带无线网络中信道分配的系统和方法。 该系统包括微小区基站，至少一个宏小区基站，移动台和信道分配中心。 当移动站进行/接收呼叫或执行切换时，信道分配中心使用重新按需（RoD）方案向移动台分配宏小区基站或微小区基站的无线信道。 RoD具有以下步骤。 首先，如果可用，则试图分配微小区信道。 如果没有微小区信道可用，则尝试分配宏小区信道。 第三，如果没有宏小区信道可用，则执行重新打包以执行另一个移动台的呼叫从宏小区到另一个微小区的切换，并且向移动台分配回收的宏小区信道。 否则，没有重新打包呼叫可用，移动台被阻止或强制终止。 通过本发明，可以减少多频带无线网络中的移动台的呼叫阻塞概率和呼叫切换率，从而可以提高用户的满意度。
