提出了一种全半速率自适应切换的算法，基于话务情况，自适应调整话务忙门限，实现全半速率占比动态分配。该算法通过网络选择路损、转换电平门限和质量保护门限来保证质量及容量，通过全半切换的统计、判决时间来避免乒乓切换和保证信道连续性，并最终归结为约束优化问题，且利用罚函数法进行求解。最后应用于现网高话务量场景进行功能验证。

A half/full rate adaptive handover algorithm is proposed. Busy traffic threshold can be adaptively adjusted to achieve dynamic allocation of half/full rate ratio based on traffic. This algorithm can protect quality and quantity by network selective path loss, switching level threshold and quality protection threshold. It also can avoid ping-pong handover and ensure channel continuity by statistical time and decision time of half/full handover. All the problems can come down to a constrained optimization problem which can be solved by penalty function. Finally, penalty function is used in busy traffic scene to verify its function.
