背景技术Background technique

集中式处理无线接入网(Centralized-Radio Access Network,C-RAN)是一种新型无线接入网架构，主要由分布式远端射频单元(Remote Radio Unit)、天线、云基带单元(Cloud-Baseband Unit,Cloud-BBU)和连接它们的传输网络组成。Cloud-BBU是指多个BBU集中在一起，通过交换机进行BBU间数据的交换，可以实现基带资源集中使用，即实现资源池，提高基带资源利用率。同时，通过C-RAN架构，基站间可以协同处理数据，比如实现上行协作多点传输，联合调度，载波聚合等，以获得更好的小区边缘用户体验以及提升网络容量。Centralized-Radio Access Network (C-RAN) is a new type of wireless access network architecture, mainly consisting of distributed remote radio unit (Remote Radio Unit), antenna, and cloud baseband unit (Cloud- Baseband Unit, Cloud-BBU) and the transport network connecting them. A cloud-BBU is a group of multiple BBUs that are connected together to exchange data between BBUs. This allows centralized use of baseband resources, that is, resource pools and resource utilization. At the same time, through the C-RAN architecture, the base stations can jointly process data, such as uplink coordinated multipoint transmission, joint scheduling, carrier aggregation, etc., to obtain a better cell edge user experience and improve network capacity.

目前，资源池方案主要是在某基带板小区业务繁忙，而另外的基带板小区业务较空时，将繁忙基带板中的部分小区业务迁移到业务较空的基带板，实现基带资源共享。采用这种方案时，基带资源利用率依然较低。At present, the resource pool solution is mainly when the service of a baseband board cell is busy, and when the baseband board cell service is relatively empty, part of the cell service in the busy baseband board is migrated to a baseband board with a relatively empty service to realize baseband resource sharing. With this approach, baseband resource utilization remains low.
