<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">优化实施<span style="color: black;">方法</span></p>
<h3 style="color: black; text-align: left; margin-bottom: 10px;"><span style="color: black;">1、容量优化</span></h3>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">容量问题可<span style="color: black;">经过</span>KPI指标中的RRC最大连接用户数、用户面最大激活UE数、上下行PRB平均占用率来进行<span style="color: black;">评定</span>。例如:15分钟粒度PRB利用率超过70%,用户面最大激活UE数超50,<span style="color: black;">每日</span><span style="color: black;">显现</span>4次可认为是容量问题。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">2、 覆盖优化</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">按照</span>MR数据及卡顿小区TA和RSRP指标分析,对过覆盖、弱覆盖、质差区域进行RF优化<span style="color: black;">调节</span>。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">3、参数优化</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">符号关断:</span></strong><span style="color: black;">为了降低能耗现网,前期大部分站点已开启节能策略(符号关断),但<span style="color: black;">因为</span>小区进入符号关段后,数据只能在非关断符号发送,对时延有<span style="color: black;">必定</span>影响;<span style="color: black;">同期</span>需要满足特定的<span style="color: black;">要求</span>被关断符号<span style="color: black;">才可</span>被唤醒,对业务感知影响<span style="color: black;">很强</span>。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">DRX优化:</span></strong><span style="color: black;">DRX参数组<span style="color: black;">重点</span>优化原则是使UE尽可能的处在监听状态下,缩短UE发送/接收等待时延。在休眠态下UE不监听PDCCH信道,减少长周期时间,以及尽可能的<span style="color: black;">增多</span>短周期频次,<span style="color: black;">能够</span>相应的减少UE终端发送时长,<span style="color: black;">提高</span>感知时延指标。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">SR周期优化:</span></strong><span style="color: black;">终端上行数据发送之前,需要发送SR向基站申请上行调度资源, SR传输周期越大,等待的时延<span style="color: black;">亦</span>就越大。故缩短SR传输周期可缩短时延。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">4、特性功能<span style="color: black;">安排</span></span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">TCP ACK分裂:</span></strong><span style="color: black;">功能使能后,在TCP传输的慢<span style="color: black;">起步</span><span style="color: black;">周期</span>TCP ACK数量<span style="color: black;">更加多</span>。<span style="color: black;">能够</span>加快TCP发送窗口的扩展。<span style="color: black;">针对</span>TCP层采用隔段确认方式的场景,<span style="color: black;">经过</span>TCP ACK分裂变为逐段确认,<span style="color: black;">能够</span>有效加快TCP慢<span style="color: black;">起步</span>过程的发送窗口增长速度,<span style="color: black;">这般</span>每一轮RTT周期<span style="color: black;">能够</span>发送的数据量增长更快。从而使得某网站主页的主框架文件的下发轮次得到降低,即<span style="color: black;">经过</span>ACK分裂加速了服务器的下行发包的速度。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">TCP乱序重排:</span></strong><span style="color: black;">基站侧对核心网发来的乱序的TCP数据包进行重排序,从而在<span style="color: black;">必定</span>程度上减少不必要的下行重传,<span style="color: black;">加强</span>发送效率,可能对时延和速率都有<span style="color: black;">必定</span>增益,<span style="color: black;">针对</span>下行传输报文乱序的场景有效。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">DNS代理功能:</span></strong><span style="color: black;">基站<span style="color: black;">保留</span>域名和IP的对应关系信息,UE请求的DNS<span style="color: black;">查找</span>,<span style="color: black;">倘若</span>基站存在对应的域名和IP对应关系,eNB直接给UE发送DNS<span style="color: black;">查找</span>响应并<span style="color: black;">同期</span>把DNS请求发送给应用服务器,并<span style="color: black;">按照</span>影响结果更新域名和IP对应关系</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">HTTP预调度功能/GET预调度:</span></strong><span style="color: black;">HTTP预调度:<span style="color: black;">经过</span>对TCP端口进行识别,<span style="color: black;">倘若</span>是识别为80/8080/443端口,当有下行数据包主动进行上行的预调度用于反馈上行的TCP ACK,<span style="color: black;">按照</span><span style="color: black;">每一个</span>下行数据包的<span style="color: black;">体积</span>,预估TCP ACK的个数,<span style="color: black;">按照</span>预配置的ACK的<span style="color: black;">体积</span>,预估上行预调度的<span style="color: black;">体积</span>。</span><strong style="color: blue;"><span style="color: black;">GET</span><span style="color: black;">预调度:</span></strong><span style="color: black;">对下行的SYN ACK进行识别,当识别后,主动进行上行的预调度把三次握手的上行ACK<span style="color: black;">信息</span>以及后续的GET<span style="color: black;">信息</span>包住,不需要<span style="color: black;">经过</span>触发SR上行数据发送。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">5、光功率核查</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">光口收发功率<span style="color: black;">小于</span>-12dBm可能会<span style="color: black;">引起</span>传输丢包的现象,对业务<span style="color: black;">导致</span><span style="color: black;">必定</span>的影响。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">6、干扰处理</span></p>
