Description

一种实现通信系统节能的方法及设备
技术领域
本发明实施例涉及通信技术领域， 尤其涉及一种实现通信系统节能的方法 及设备。 背景技术
基于微小区的室内通信具有昼夜通信量反差大的特点。 另外， 由于微小区 的覆盖范围较小， 不是每时每刻都有通信需求。 因此， 实现微小区的智能节能 将成为绿色通信技术的主要研究课题之一。
现有的一种基于噪声功率探测的室内 Femto Cell (微微蜂窝） AP ( Access
Point, 无线接入点） 节能方案。 该方案的工作原理如下：
Femto Cell AP与宏基站工作在不同频带上， Femto Cell AP可以将用户设 备向宏网络发送的信号视为噪声， 基于噪声功率探测技术判断微小区内是否有 用户存在。 当 Femto Cell AP检测到用户设备的发射功率高于设定的噪声功率探 测门限， 则从休眠状态转为激活状态； 否则， 保持休眠状态。 其中， 休眠状态 是指 Femto Cell AP不发送导频信号， 激活状态是指 Femto Cell AP发送导频信 号。
发明人在实现本发明的过程中， 发现现有技术中至少存在如下问题： 上述基于噪声功率探测的微小区智能节能方案的应用范围有限， 当微小区 没有被宏小区覆盖时， 则不能应用该方案实现微小区的智能节能。 另外， 当外 部噪声干扰较大时， Femto Cell AP会因为检测到较高的外部噪声而被误激活， 无法真正实现智能节能。 发明内容
本发明的实施例提供了一种实现通信系统节能的方法及设备， 从而有效降 低微小区基站的能耗。
本发明的目的是通过以下技术方案实现的：
一种实现通信系统节能的方法，基站在检测到小区中没有用户设备驻留时， 进入休眠状态， 该方法包括：
处于休眠状态的所述基站接收用户设备发来的应答信号， 所述应答信号是 所述用户设备在接收到所述基站以 N倍于无线帧长的周期而发送的寻呼信号后 发送的；
所述基站切换到激活状态。
一种节能基站， 所述基站在检测到小区中没有用户设备驻留时， 进入休眠 状态， 所述基站包括：
信息接收模块， 用于接收用户设备发来的应答信号， 并触发状态切换模块 工作，所述应答信号是所述用户设备在接收到所述基站以 N倍于无线帧长的周期 而发送的寻呼信号后发送的；
状态切换模块， 用于将基站切换到激活状态。
一种微小区接入网关， 包括：
请求接收模块， 用于接收微小区的基站发送的激活请求信息， 所述激活请 求信息用来请求激活所述基站的相邻小区的基站；
激活指示模块， 用于指示所述微小区的基站的相邻小区的基站切换到激活 状态。
由上述本发明的实施例提供的技术方案可以看出， 本发明实施例提供的技 术方案应用在室内通信系统时，微小区的基站以 N倍于无线帧长的周期发送寻呼 信号， 并根据用户设备反馈的应答信号触发切换至激活状态。 由于不依赖于用 户设备是否向宏网络发送信号， 从而在没有宏网络覆盖的地区也能应用微小区 的智能节能方法， 扩大了微小区智能节能方法的应用范围。 又由于直接根据用 户终端的反馈决定是否进入激活状态， 因此更准确的感知微小区中是否有用户 设备驻留， 提高了状态切换的准确性， 进而提高了微小区智能节能的可靠性。 附图说明
