Description

等效负载时间的计算及负载均衡方法、系统、设备和基站 技术领域
本发明涉及通信技术领域，具体而言，涉及一种分量载波的等效负载时间的计算方法、一种分量载波的等效负载时间的计算系统、一种业务数据在下行传输过程的负载均衡方法和一种业务数据在下行传输过程的负载均衡系统、一种负载均衡设备和一种基站。
背景技术
下行负载均衡技术主要包括循环分发(CD，Circular Dispatching)技术、最小负载(LL，Least Load)技术和移动散列(MH，Mobile Hashing)，其中，循环分发技术是给接收调度的用户轮流的分配各个成员载波；最小负载技术就是当每个用户接入时，为其选择当前负载最小的成员载波进行调度；移动散列技术是利用哈希函数使得各个用户选择成员载波时避免冲突从而将各个用户均匀地分布到各个成员载波上，目前，最小负载技术是下行负载均衡技术的主流发展方向。
相关技术中，最小负载技术是在统计分量载波的负载时，对该分量载波上的用户进行计数，或者是累积每个用户的剩余数据长度，将待调度的用户数据包分配给剩余数据包总长度与成员载波带宽之比最小的成员载波。但是在实际的通信环境中，每个用户的位置和信道条件是有差异的，最小负载技术简单地以用户数或数据包长度代表负载的大小，没有充分考虑信道质量对负载的影响，因而并不能准确地反映某个成员载波的实际负载，造成对时域资源和频域资源的浪费。
因此，需要一种新的下行负载均衡方案以提高负载分配准确率和合理性以提高时域资源和频域资源的利用效率成为亟待解决的技术问题。
发明内容
本发明正是基于上述问题，提出了一种分量载波的等效负载时间的计算方案、一种业务数据在下行传输过程的负载均衡方案、一种负载设备和一种基站，通过所有的无线承载的剩余数据包长度和下行传输速率的比值确定等效负载时间，进而确定最小等效负载时间对应的分量载波以进行业务数据的下行传输，准确地反映了成员载波的实际负载，进而提高了时域资源和频域资源的利用率，加快了数据传输的效率。
