Description

一种准入控制方法、负载控制方法及网络设备 技术领域
本发明实施例涉及通信技术领域，尤其涉及一种准入控制方法、负载控制方法及网络设备。
背景技术
在移动通信系统中，每个处于专用连接状态的在线用户即使没有业务数据传输，也要发送控制信息以保持与网络的连通性，这些控制信息需要占用一定的无线空口资源，同时，如果用户有业务数据传输，这些业务数据也要消耗一定的无线空口资源。而系统的无线空口资源是有限的，当系统中存在大量处于专用连接状态的在线用户时，会出现无线空口资源拥塞，从而产生一系列问题。例如，大量在线用户的控制信息占用了较多无线空口资源，导致业务数据传输可用的无线空口资源变少，从而导致用户业务数据传输速率下降，用户的业务体验差，同时小区吞吐率也会下降，因而出现了基于空口资源的准入控制技术。这种准入控制技术通常是将业务按照所要求的服务质量(Quality of Service，QoS)进行分类，例如将业务分为语音业务、流业务、高时延敏感交互业务、保证速率业务和尽力而为业务，对每类业务分别设置准入门限，当用户请求接入时，携带请求的业务的QoS，RNC根据该QoS判断请求该类业务的已接入用户数是否大于该类业务的准入门限，若不大于，则允许接入，否则拒绝接入。
上述准入控制方法存在一些问题，例如QoS分类方法与实际业务类型有时不能很好的对应，如在网页上打开的视频流按照QoS分类方法会被认为是高时延敏感交互业务，而不是流业务，其准入门限的设置可能就不合理，影响用户体验。另外，对每类业务分别设置准入门限，仅根据用户申请业务的QoS类的业务准入门限来控制该类用户的准入，即仅考虑请求该类业务的用户的满意度，不考虑小区内请求其他业务的用户的满意度，可能会使得请求某类业务的用户持续接入，导致小区空口资源拥塞，而请求其他类业务的用户都无法接入。
为了兼顾用户准入的公平性，有另一种准入控制方法，即针对小区内所有类型的业务统一设置准入阈值，在控制用户接入的过程中，根据业务的奖赏值 计算系统的平均收益，然后根据系统的平均收益动态调整准入阈值，在系统接纳呼叫时给予奖赏，在系统拒绝呼叫或者由于准入阈值设置不当而造成资源浪费时给予惩罚，以达到降低新呼叫阻塞率和切换呼叫中断率的目的。这种准入控制方法的主要目的是降低新呼叫阻塞率和切换呼叫中断率，使更多的用户能够接入网络，因此通常会无视小区内接入用户的业务体验，接入用户的业务体验通常很差；同时大量用户在线时，会导致控制信息占用较多空口资源，导致小区吞吐率下降，用户数据传输效率降低。

目前的网络设备通常会根据网络的负载能力为每个小区设置准入阈值，即 初始准入阈值，在终端接入的过程中，网络设备会按照系统的平均收益动态调整该准入阈值，但这种做法会产生小区内用户业务体验很差，小区吞吐率低，用户数据传输效率低等一系列问题。具体实现中，网络设备可以为无线网络控制器(Radio Network Controller，RNC)，或者为基站NodeB，此处不做具体限定。
因而，本发明实施例提供了一种准入控制方法、负载控制方法及网络设备，能够在兼顾用户准入公平的前提下，提高用户数据传输效率，提高小区吞吐率，提升用户的业务满意度。
请参阅图1，本发明网络设备一个实施例包括：
第一计算单元101，用于在第一预置时长内计算小区的业务整体满意度，小区的业务整体满意度为小区内各类业务的满意度的加权求和；

阈值调整单元103，用于根据准入阈值调整量将小区的第一准入阈值调整为第二准入阈值；
接收单元104，用于接收终端发送的接入请求；
控制单元105，用于根据第二准入阈值对终端执行准入控制。
另外，本实施例的网络设备还可以包括功率判决单元106，功率判决单元106用于在接收单元104接收终端发送的接入请求之后，获取第二预置时长内小区的下行发射功率平均值，判断下行功率发射平均值是否大于下行发射功率拥塞门限值，第二预置时长小于第一预置时长；若大于，则由控制单元105根据第二准入阈值对终端执行准入控制；若不大于，则控制单元105不对终端执行准入控制。
具体实现中，网络设备可根据应用的性质对应用进行分类，例如可将应用分为语音业务，视频业务，Web业务，文件下载，文件上传，即时通讯(InstantMessaging，IM)业务等。第一计算单元101在第一预置时长内计算各类业务的满意度，每类业务的满意度为该类业务满意话单数目与该类业务的话单总数目的比值，将小区内各类业务的满意度加权求和得到小区的业务整体满意度。第一计算单元101通常会在当前小区内所有业务的话单总数大于或等于预设话单总数门限值时计算小区的业务整体满意度，在话单总数小于预设话 单总数门限值时一般不计算小区的业务整体满意度。
具体地，第一计算单元101可按照如下方式确定每类业务的满意话单：
对于语音业务，可以将当前话单的平均主观意见分(Mean Opinion Score，MOS)与语音业务满意门限进行比较，若当前话单的MOS分高于语音业务满意门限，则确定当前话单为满意话单，否则为不满意话单；
对于视频业务，可以将当前话单承载的初始缓冲时延指标、停顿占比指标或平均吞吐率与视频业务满意门限(如时延门限、吞吐率门限)进行比较，若当前话单承载的初始缓冲时延指标、或停顿占比指标低于时延门限，或者当前话单承载的平均吞吐率高于吞吐率门限，则确定当前话单为满意话单，否则为不满意话单；
对于Web业务，可以将当前话单的网页显示时延指标或者网页平均下载速率与Web业务满意门限(如时延门限、下载速率门限)进行比较，若当前话单的网页显示时延指标低于时延门限，或者当前话单的网页平均下载速率高于下载速率门限，则确定当前话单为满意话单，否则为不满意话单；
对于文件下载业务，可以将当前话单显示的平均下载速率与文件下载业务满意门限进行比较，若当前话单显示的平均下载速率高于文件下载业务满意门限，则确定当前话单为满意话单，否则为不满意话单；
对于文件上传业务，可以将当前话单显示的平均上传速率与文件上传业务满意门限进行比较，若当前话单显示的平均上传速率高于文件上传业务满意门限，则确定当前话单为满意话单，否则为不满意话单；
对于IM业务，可以将当前话单显示的时延或者发送成功率与IM业务满意门限(如时延门限，成功率门限)进行比较，若当前话单显示的时延低于时延门限，或发送成功率高于成功率门限，则确定当前话单为满意话单，否则为不满意话单。
确定每类业务的满意话单之后，第一计算单元101可按照如下公式计算小区的业务整体满意度：

计算准入阈值调整量，其中，A0至AN为差值的具体取值，pj为区间[A0,A1)内xj项的系数，lj为区间[A1,A2)内xj项的系数，mj为区间[AN-1,AN)内xj项的系数。在上面两个计算准入阈值调整量的公式中，当业务整体满意度与整体满意度目标值之间的差值为正数时，整体调整趋势是将准入阈值增大，且业务整体满意度与整体满意度目标值之间的差值越大，准入阈值调整量越大；当业务整体满意度与整体满意度目标值之间的差值为负数时，整体调整趋势是将准入阈值减小，且业务整体满意度与整体满意度目标值之间的差值的绝对值越大，准入阈值调整量的绝对值越大。
在第二计算单元102得到准入阈值调整量之后，阈值调整单元103根据准入阈值调整量将小区的第一准入阈值调整为第二准入阈值。具体地，阈值调整单元103可根据公式η2＝η1+f(x)得到第二准入阈值，其中，η2为第二准入阈值，η1 为第一准入阈值，f(x)为准入阈值调整量。
需要说明的是，在第一次调整小区的准入阈值时，第一准入阈值可以是初始准入阈值，在第二次、第三次及以后的调整过程中，第一准入阈值可以是最近一次调整得到的准入阈值。
接收单元104接收终端发送的接入请求，该接入请求用于请求接入当前小区，在接收单元104接收到终端发送的接入请求之后，可先由功率判决单元106获取第二预置时长内该小区的下行发射功率平均值，判断下行功率发射平均值是否大于下行发射功率拥塞门限值(即短时下行发射功率拥塞门限值)，第二预置时长小于第一预置时长；若大于，则说明当前小区的资源紧张，则触发控制单元105根据第二准入阈值对终端执行准入控制，以限制接入当前小区的终端数量，提升在线终端的业务满意度；若不大于，则说明当前小区的资源比较充裕，控制单元105不对终端执行准入控制，即允许终端接入，以充分利用小区资源。
具体地，控制单元105根据第二准入阈值对终端执行准入控制的过程可如下：控制单元105可获取当前小区的在线终端的状态相关信息，该状态相关信息可以是当前小区内处于CELL_DCH状态的在线终端的数量，或者是当前小区内处于CELL_DCH状态的在线分组交换(Packet Switch，PS)域尽力而为(Best Effort，BE)业务的无线承载(radio bearer，RB)个数，或者处于CELL_DCH状态的在线激活的PS域BE业务的RB个数，并将所获取的当前小区的在线终端的状态相关信息与第二准入阈值进行比较，若当前小区的在线终端的状态相关信息低于第二准入阈值，则允许该终端接入，否则拒绝该终端接入。
当控制单元105根据第二准入阈值执行准入控制时，若拒绝该终端接入当前小区，控制单元105可采用以下任意一种方式对拒绝接入当前小区的终端进行处理：将拒绝接入当前小区的终端配置在CELL_FACH态、或CELL_PCH态、或URA_PCH态；或者拒绝接入当前小区的终端配置在IDLE态；或者将拒绝接入当前小区的终端调整至当前小区的邻区，以减少这些终端占用的控制资源。
另外，在没有计算小区的业务整体满意度时(例如当前小区的所有业务话单总数少于预设话单总数门限值)，如果发生了基于第一准入阈值的准入拒绝， 或在第一预置时长内小区下行发射功率的平均值小于等于长时下行发射功率拥塞门限且发生了基于第一准入阈值的准入拒绝，则可以将第一准入阈值调整为第三准入阈值，然后根据第三准入阈值执行准入控制。
具体地，可按照如下方法将第一准入阈值调整为第三准入阈值：
第一：将第一准入阈值加上固定阈值调整量得到第三准入阈值；
第二：将第一准入阈值加上可变阈值调整量得到第三准入阈值；可变阈值调整量可由如下基于准入拒绝次数的分段多项式函数决定：
Figure PCTCN2015076149-appb-000022
其中，f(y)可变阈值调整量，其中，A0至AN为准入拒绝次数的具体取值，pj为区间[A0,A1)内yj项的系数，lj为区间[A1,A2)内yj项的系数，mj为区间[AN-1,AN)内yj项的系数。该公式中，准入拒绝的次数越多，可变阈值调整量越大。
本实施例中，第一计算单元首先在第一预置时长内计算小区的业务整体满意度，小区的业务整体满意度为小区内各类业务的满意度的加权求和，然后第二计算单元基于小区的业务整体满意度与整体满意度目标值之间的差值计算准入阈值调整量，阈值调整单元根据准入阈值调整量将小区的第一准入阈值调整为第二准入阈值，在接收单元接收到终端发送的接入请求之后，控制单元根据第二准入阈值对终端执行准入控制。即本发明实施例中，对所有请求接入该小区的终端均采用同一准入阈值，因而能够兼顾用户准入的公平性，在控制用户接入的过程中，阈值调整单元会根据业务整体满意度动态调整准入阈值，以提升用户的业务满意度，提高用户数据传输效率，提高小区吞吐率。
请参阅图2，本发明网络设备另一实施例包括：存储器201、处理器202及接收器203，其中处理器202用于调用存储器201中存储的软件程序以执行如下操作：
在第一预置时长内计算小区的业务整体满意度，小区的业务整体满意度为小区内各类业务的满意度的加权求和；
基于小区的业务整体满意度与整体满意度目标值之间的差值计算准入阈值调整量；
根据准入阈值调整量将所述小区的第一准入阈值调整为第二准入阈值；
控制接收器203接收终端发送的接入请求；
根据第二准入阈值对终端执行准入控制。
上面介绍了用于进行准入控制的网络设备，下面将介绍用于负载控制的网络设备，请参阅图3，本实施例的网络设备包括：
计算单元301，用于在预置时长内计算小区的业务整体满意度，小区的业务整体满意度为小区内各类业务的满意度的加权求和；
处理单元302，用于当小区的业务整体满意度小于业务体验初级拥塞门限且大于业务体验严重拥塞门限时，将小区内个第一预设数量的第一预设终端调整至满足预设条件的邻区，第一预设终端包括处于CELL_FACH态、CELL_PCH态及URA_PCH态中任意一种状态的终端，满足预设条件的邻区为与当前小区相邻且业务整体满意度大于业务体验初级拥塞门限的小区。
具体实现中，当前小区的业务整体满意度的计算方法可参阅前述实施例的描述，此处不再赘述。
在实际应用中，网络设备通常会为每个小区设置两个业务体验拥塞门限，即业务体验初级拥塞门限和业务体验严重拥塞门限，业务体验初级拥塞门限的取值一般为0.7～0.8，业务体验严重拥塞门限的取值一般为0.3～0.4。若某个小区的业务整体满意度大于业务体验初级拥塞门限，则说明该小区内用户的业务满意度较高；若某个小区的业务整体满意度小于业务体验初级拥塞门限且大于业务体验严重拥塞门限，则说明该小区内用户的业务满意度较低；若某个小区的业务整体满意度小于业务体验严重拥塞门限，则说明该小区内用户的业务满意度极低。
当计算单元301计算得到当前小区的业务整体满意度之后，处理单元302可将当前小区的业务整体满意度与所设置的业务体验拥塞门限进行比较。若当前小区的业务整体满意度大于业务体验初级拥塞门限，则不做调整。若当前小区的业务整体满意度小于业务体验初级拥塞门限且大于业务体验严重拥塞门限，则将当前小区内个第一预设数量的第一预设终端调整至满足预设条件的邻区，第一预设终端包括当前小区内处于CELL_FACH态、CELL_PCH态及 URA_PCH态中任意一种状态的终端，满足预设条件的邻区为与当前小区相邻且业务整体满意度大于业务体验初级拥塞门限的小区；若没有满足预设条件的邻区，则不做调整。
若当前小区的业务整体满意度小于业务体验严重拥塞门限，则将当前小区内个第二预设数量的第二预设终端调整至满足预设条件的邻区，第二预设终端包括处于CELL_DCH态、CELL_FACH态、CELL_PCH态及URA_PCH态中任意一种状态的终端；若没有满足预设条件的邻区，则将当前小区内第三预设数量的处于CELL_DCH态的终端配置在CELL_FACH态、或CELL_PCH态、或URA_PCH态，或IDLE态。
需要说明的是，本实施例的网络设备，可以在按照现有技术的方法执行准入控制之后，按照小区的业务整体满意度执行负载控制，也可以在按照本发明前述基于小区的业务整体满意度执行准入控制之后，按照小区的业务整体满意度执行负载控制，此处不做限定。
本实施例中，处理单元会根据当前小区的业务整体满意度调整当前小区的负载，以提升用户的业务满意度，提高用户数据传输效率，提高小区吞吐率。
请参阅图4，本发明网络设备另一实施例包括存储器401及处理器402，处理器402执行存储器401中存储的软件程序以执行如下操作：
在预置时长内计算小区的业务整体满意度，小区的业务整体满意度为小区内各类业务的满意度的加权求和；
当小区的业务整体满意度小于业务体验初级拥塞门限且大于业务体验严重拥塞门限时，将小区内个第一预设数量的第一预设终端调整至满足预设条件的邻区，第一预设终端包括处于CELL_FACH态、CELL_PCH态及URA_PCH态中任意一种状态的终端，满足预设条件的邻区为与该小区相邻且业务整体满意度大于业务体验初级拥塞门限的小区。
下面介绍本发明提供的准入控制方法，请参阅图5，本实施例的准入控制方法包括：
501、在第一预置时长内计算小区的业务整体满意度，小区的业务整体满意度为小区内各类业务的满意度的加权求和；
具体实现中，网络设备可根据应用的性质对应用进行分类，例如可将应用分为语音业务，视频业务，Web业务，文件下载，文件上传，IM业务等。在 第一预置时长内计算各类业务的满意度，每类业务的满意度为该类业务满意话单数目与该类业务的话单总数目的比值，将小区内各类业务的满意度加权求和得到小区的业务整体满意度。网络设备通常会在当前小区内所有业务的话单总数大于或等于预设话单总数门限值时计算小区的业务整体满意度，在话单总数小于预设话单总数门限值时一般不计算小区的业务整体满意度。
具体地，可按照如下方式确定每类业务的满意话单：
对于语音业务，可以将当前话单的平均主观意见分(Mean Opinion Score，MOS)与语音业务满意门限进行比较，若当前话单的MOS分高于语音业务满意门限，则确定当前话单为满意话单，否则为不满意话单；
对于视频业务，可以将当前话单承载的初始缓冲时延指标、停顿占比指标或平均吞吐率与视频业务满意门限(如时延门限、吞吐率门限)进行比较，若当前话单承载的初始缓冲时延指标、或停顿占比指标低于时延门限，或者当前话单承载的平均吞吐率高于吞吐率门限，则确定当前话单为满意话单，否则为不满意话单；
对于Web业务，可以将当前话单的网页显示时延指标或者网页平均下载速率与Web业务满意门限(如时延门限、下载速率门限)进行比较，若当前话单的网页显示时延指标低于时延门限，或者当前话单的网页平均下载速率高于下载速率门限，则确定当前话单为满意话单，否则为不满意话单；
对于文件下载业务，可以将当前话单显示的平均下载速率与文件下载业务满意门限进行比较，若当前话单显示的平均下载速率高于文件下载业务满意门限，则确定当前话单为满意话单，否则为不满意话单；
对于文件上传业务，可以将当前话单显示的平均上传速率与文件上传业务满意门限进行比较，若当前话单显示的平均上传速率高于文件上传业务满意门限，则确定当前话单为满意话单，否则为不满意话单；
对于IM业务，可以将当前话单显示的时延或者发送成功率与IM业务满意门限(如时延门限，成功率门限)进行比较，若当前话单显示的时延低于时延门限，或发送成功率高于成功率门限，则确定当前话单为满意话单，否则为不满意话单。
确定每类业务的满意话单之后，可按照如下公式计算小区的业务整体满意度：
即根据公式
Figure PCTCN2015076149-appb-000023
或者
Figure PCTCN2015076149-appb-000024
计算小区的业务整体满意度，其中
Figure PCTCN2015076149-appb-000025
Q为小区的业务整体满意度，i为业务类型，λi为第i类业务满意话单数目，ai为第i类业务满意话单数目的权重，βi为第i类业务话单总数目，ki为第i类业务话单总数目的权重。
502、基于小区的业务整体满意度与整体满意度目标值之间的差值计算准入阈值调整量；
具体地，可先根据公式x＝Q-Q0计算小区的业务整体满意度与整体满意度目标值之间的差值，其中，x为所述差值，Q为业务整体满意度，Q0为整体满意度目标值；
然后根据公式
Figure PCTCN2015076149-appb-000026
计算准入阈值调整量，其中f(x)为准入阈值调整量，j为整数，nj为xj项的系数；
或者根据公式
Figure PCTCN2015076149-appb-000027
计算准入阈值调整量，其中，A0至AN为差值的具体取值，pj为区间[A0,A1)内xj项的系数，lj为区间[A1,A2)内xj项的系数，mj为区间[AN-1,AN)内xj项的系数。在上面两个计算准入阈值调整量的公式中，当业务整体满意度与整体满意度目标值之间的差值为正数时，整体调整趋势是将准入阈值增大，且业务整体满意度与整体满意度目标值之间的差值越大，准入阈值调整量越大；当业务整体满意度与整体满意度目标值之间的差值为负数时，整体调整趋势是将准入阈值减小，且业务整体满意度与整体满意度目标值之间的差值的绝对值越大，准入阈值调整量的绝对值越大。
503、根据准入阈值调整量将小区的第一准入阈值调整为第二准入阈值；
具体地，可根据公式η2＝η1+f(x)得到第二准入阈值，其中，η2为第二准入阈值，η1为第一准入阈值，f(x)为准入阈值调整量。
需要说明的是，在第一次调整小区的准入阈值时，第一准入阈值可以是初始准入阈值，在第二次、第三次及以后的调整过程中，第一准入阈值可以是最近一次调整得到的准入阈值。
504、接收终端发送的接入请求；
该接入请求用于请求接入当前小区。
505、根据第二准入阈值对终端执行准入控制。
具体实现中，在接收到终端发送的接入请求之后，可先获取第二预置时长内该小区的下行发射功率平均值，判断下行功率发射平均值是否大于下行发射功率拥塞门限值(即短时下行发射功率拥塞门限值)，第二预置时长小于第一预置时长；若大于，则说明当前小区的资源紧张，则根据第二准入阈值对终端执行准入控制，以限制接入当前小区的终端数量，提升在线终端的业务满意度；若不大于，则说明当前小区的资源比较充裕，则可不对终端执行准入控制，即允许终端接入，以充分利用小区资源。
具体地，根据第二准入阈值对终端执行准入控制的过程可如下：可获取当前小区的在线终端的状态相关信息，该状态相关信息可以是当前小区内处于CELL_DCH状态的在线终端的数量，或者是当前小区内处于CELL_DCH状态的在线分组交换(Packet Switch，PS)域尽力而为(Best Effort，BE)业务的无线承载(radio bearer，RB)个数，或者处于CELL_DCH状态的在线激活的PS域BE业务的RB个数，并将所获取的当前小区的在线终端的状态相关信息与第二准入阈值进行比较，若当前小区的在线终端的状态相关信息低于第二准入阈值，则允许该终端接入，否则拒绝该终端接入。
当根据第二准入阈值执行准入控制时，若拒绝该终端接入当前小区，则可采用以下任意一种方式对拒绝接入当前小区的终端进行处理：将拒绝接入当前小区的终端配置在CELL_FACH态、或CELL_PCH态、或URA_PCH态；或者拒绝接入当前小区的终端配置在IDLE态；或者将拒绝接入当前小区的终端调整至当前小区的邻区，以减少这些终端占用的控制资源。
另外，在没有计算小区的业务整体满意度时(例如当前小区的所有业务话单总数少于预设话单总数门限值)，如果发生了基于第一准入阈值的准入拒绝，或在第一预置时长内小区下行发射功率的平均值小于等于长时下行发射功率拥塞门限且发生了基于第一准入阈值的准入拒绝，则可以将第一准入阈值调整为第三准入阈值，然后根据第三准入阈值执行准入控制。
具体地，可按照如下方法将第一准入阈值调整为第三准入阈值：
第一：将第一准入阈值加上固定阈值调整量得到第三准入阈值；
第二：将第一准入阈值加上可变阈值调整量得到第三准入阈值；可变阈值调整量可由如下基于准入拒绝次数的分段多项式函数决定：
Figure PCTCN2015076149-appb-000028
其中，f(y)可变阈值调整量，其中，A0至AN为准入拒绝次数的具体取值，pj为区间[A0,A1)内yj项的系数，lj为区间[A1,A2)内yj项的系数，mj为区间[AN-1,AN)内yj项的系数。该公式中，准入拒绝的次数越多，可变阈值调整量越大。
本实施例中，首先在第一预置时长内计算小区的业务整体满意度，小区的业务整体满意度为小区内各类业务的满意度的加权求和，然后基于小区的业务整体满意度与整体满意度目标值之间的差值计算准入阈值调整量，根据准入阈值调整量将小区的第一准入阈值调整为第二准入阈值，在接收到终端发送的接入请求之后，根据第二准入阈值对终端执行准入控制。即本发明实施例中，对所有请求接入该小区的终端均采用同一准入阈值，因而能够兼顾用户准入的公平性，在控制用户接入的过程中，阈值调整单元会根据业务整体满意度动态调整准入阈值，以提升用户的业务满意度，提高用户数据传输效率，提高小区吞吐率。

602、当小区的业务整体满意度小于业务体验初级拥塞门限且大于业务体验严重拥塞门限时，将小区内个第一预设数量的第一预设终端调整至满足预设条件的邻区，第一预设终端包括处于CELL_FACH态、CELL_PCH态及URA_PCH态中任意一种状态的终端，满足预设条件的邻区为与该小区相邻且业务整体满意度大于业务体验初级拥塞门限的小区。
在实际应用中，网络设备通常会为每个小区设置两个业务体验拥塞门限，即业务体验初级拥塞门限和业务体验严重拥塞门限，业务体验初级拥塞门限的取值一般为0.7～0.8，业务体验严重拥塞门限的取值一般为0.3～0.4。若某个小区的业务整体满意度大于业务体验初级拥塞门限，则说明该小区内用户的业务满意度较高；若某个小区的业务整体满意度小于业务体验初级拥塞门限且大于业务体验严重拥塞门限，则说明该小区内用户的业务满意度较低；若某个小区的业务整体满意度小于业务体验严重拥塞门限，则说明该小区内用户的业务满意度极低。
当计算得到当前小区的业务整体满意度之后，可将当前小区的业务整体满意度与网络设备所设置的业务体验拥塞门限进行比较。若当前小区的业务整体满意度大于业务体验初级拥塞门限，则不做调整。若当前小区的业务整体满意度小于业务体验初级拥塞门限且大于业务体验严重拥塞门限，则将当前小区内个第一预设数量的第一预设终端调整至满足预设条件的邻区，第一预设终端包括当前小区内处于CELL_FACH态、CELL_PCH态及URA_PCH态中任意一种状态的终端，满足预设条件的邻区为与当前小区相邻且业务整体满意度大于业务体验初级拥塞门限的小区；若没有满足预设条件的邻区，则不做调整。
若当前小区的业务整体满意度小于业务体验严重拥塞门限，则将当前小区内个第二预设数量的第二预设终端调整至满足预设条件的邻区，第二预设终端包括处于CELL_DCH态、CELL_FACH态、CELL_PCH态及URA_PCH态中任意一种状态的终端；若没有满足预设条件的邻区，则将当前小区内第三预设数量的处于CELL_DCH态的终端配置在CELL_FACH态、或CELL_PCH态、或URA_PCH态，或IDLE态。
