摘要: 针对CCCH容量有限而导致大量寻呼被删除的问题,提出了一种基于分组业务的寻呼删除优化方案.该方案通过动态调整CCCH容量以分担PC业务负荷,通过重建TBF以应对小区重选,通过改变GPRS边界以适应CS业务的变化,从而最终实现话务业务的负荷均衡.分组业务对CCCH负荷影响的大量实验结果证明,该方案可较好地解决大量寻呼被删除的问题,显著地改善用户感知和网络质量,因而具有较强的可行性.Abstract: To solve the problem of cancellation of large amount of paging due to CCCH capacity limitation,then an optimization scheme for paging to packet service was proposed. By dynamically adjusting CCCH capacity,the PC business load was shared;by rebuilding TBF the community reselection was replied;through the change of GPRS boundary the CS business change was accommodated,at length,the load balanced of communication business was realized.The experiments of the impact of packet service on CCCH demonstrated that the scheme can solve the cancellation of large amount of paging and improve largely user awareness and network quality and hence,has highly feasibility.
