如图 5所示， 服务 NodeB根据一定算法判断需要去激活辅载波， 先向 UECUser Equipment, 用户设备)发送 HS-SCCH (High Speed Shared Control Channel, 高速共享控 制信道） 去激活命令，然后 NodeB内部释放辅载波占用的基带资源； NodeB再向 RNC 发送 SECONDARY UL FREQUENCY UPDATE INDICATION (上行辅载波更新指示）， 告知 RNC 需要去激活辅载波上的所有链路； RNC 再向非服务 NodeB 发送 SECONDARY UL FREQUENCY REPORT (上行辅载波报告）， 非服务 NodeB收到该 消息后， 去激活辅载波上的非服务无线链路， 释放辅载波占用的基带资源。 如图 6 所示， 服务 NodeB 根据一定算法判断需要激活辅载波， 先向 UE 发送 HS-SCCH Order激活命令， 然后服务 NodeB建立辅载波， 并为辅载波分配相应的基带 资源； 服务 NodeB 再向 RNC 发送 SECONDARY UL FREQUENCY UPDATE INDICATION, 告知 RNC需要激活辅载波上的所有无线链路。 服务 NodeB上的辅载 波无线链路取得上行同步后，会向 RNC发送无线链路恢复消息， RNC收到服务 NodeB 的无线链路恢复消息后再向非服务 NodeB 发送 SECONDARY UL FREQUENCY REPORT, 非服务 NodeB收到该消息后， 重新分配辅载波上的非服务无线链路对应的 基带资源， 然后激活辅载波上的非服务无线链路， 辅载波上的非服务无线链路同步后 非服务 NodeB会向 RNC发送无线链路恢复消息。 具体地， 基站内部可以包括有基带 DSP (Digital Signal Processing, 数字信号处理 器）模块和基带资源模块， 如图 7所示， 基带 DSP模块根据一定算法判断需要去激活 辅载波， 则向基带资源模块发送辅载波去激活消息， 基带资源模块收到辅载波去激活 消息后， 就释放辅载波占用的 CE资源、 搜索资源、 进程实例、 内存以及帧缓存等资 源。 然后再向基带 DSP模块发送辅载波去激活响应消息， 基带 DSP模块接收到辅载 波激活响应消息后， 释放对应的 DSP资源。 本发明实施例的技术方案中， RNC通过无线链路建立消息、无线链路增加消息或 者无线链路重配消息， 向 NodeB发送 DC-HSUPA相关信元信息， 在信元组 Activation Information中的信元 UE Activation State的取值是 De-activated的时候， NodeB不为辅 载波分配对应的基带资源； 或者 NodeB根据一定算法判断需要去激活辅载波， NodeB 释放辅载波占用的基带资源。 当辅载波的无线条件达到一定程度， NodeB才激活辅载 波， 此时才给辅载波分配基带资源， 这样去激活辅载波不再占用 NodeB的基带资源， 能极大提高 NodeB的资源利用率， 增加用户接入数量以及提高 NodeB的吞吐量。 以上所述是本发明实施例的优选实施方式， 应当指出， 对于本技术领域的普通技 术人员来说， 在不脱离本发明所述原理的前提下， 还可以作出若干改进和润饰， 这些 改进和润饰也应视为本发明的保护范围。 工业实用性 本发明实施例可以应用到移动通信领域，可以实现在 DC-HSUPA的辅载波不需要 激活时， NodeB不为辅载波分配对应的基带资源或者释放辅载波占用的基带资源， 只 有当辅载波需要激活时才为辅载波分配相应的基带资源，这样能极大提高 NodeB的资 源利用率， 增加用户接入数量以及提高 NodeB的吞吐量。
