摘　　要：为保障用户集中的大业务场景下LTE网络的正常运转,对该场景下的LTE多载波间如何进行负载均衡的问题进行了探讨,对现网中LTE不同制式、不同带宽的载波间负载均衡案例进行了分析总结,得出LTE多载波间的负载均衡策略,并在此基础上,思考了中国联通未来进一步进行LTE扩容后的多载波间负载均衡及业务分层策略。In order to guarantee the normal operation of LTE networks in the scenario of heavy traffic with massive users, the load balancing between LTE multicarriers in the scenario was discussed. The practical cases of load balancing between multicarriers with different LTE modes and bandwidths in current networks were summarized to derive the load balancing strategy between LTE multicarriers. The load balancing between LTE multicarriers and the business stratification strategy after LTE capacity expansion for China Unicorn in the future were elaborated.
