实施例二
本发明实施例提供一种网络的分流方法,如图4所示,所述方法包括:
401、分流控制器获取小区的各个终端分别对应的信号质量及传输速率。
其中,终端对应的信号质量可以为终端的CQI(channel quality indicator,信道质量指示)、Ec/N0(码片信噪比)、Ec/Nt(码片信干噪比)、Ec/Io(导频码片信干噪比)、Eb/N0(比特信噪比)或者Eb/Nt(比特信干噪比)等,终端对应的传输速率可以为预设时间内的平均传输速率。
对于本发明实施例,存在分流控制器在同一时间内获取到终端的多个信号质量及多个传输速率的情况,此时,分流控制器可以在多个信号质量中,选择信号质量最差的值作为终端对应的信号质量;同时,分流控制器可以将多个传输速率的值进行相加,并将相加之后的传输速率作为终端对应的传输速率。
例如,对于MIMO(Multiple-Input Multiple-Output,多输入多输出)用户,存在分流控制器通过不同渠道,获取到对应的单流CQI及双流CQI的情况,此时,分流控制器选择单流CQI作为终端对应的信号质量。
可选地,在步骤401之前还可以包括:分流控制器确定小区的终端总集。
其中,小区的终端总集中包括小区的各个终端。在本发明实施例中,小区为蜂窝网络覆盖范围下的小区。
对于本发明实施例,分流控制器可以为外置的独立控制器,例如eCo等;也可以为蜂窝网络侧的蜂窝控制器,例如RNC、BSC、SGW等;还可
以为无线局域网侧的控制器,例如AC、AP等。
对于本发明实施例,小区终端总集可以为小区覆盖范围下的所有终端,也可以为小区覆盖范围下的部分终端。具体地,当小区终端总集为小区覆盖范围下的部分终端时,分流控制器选择在小区覆盖范围下,蜂窝网络中优先级较低,或者信号强度较弱,或者信号质量较差,或者传输速率较高,或者业务类型占用流量较大,或者业务类型实时性要求较低的终端作为小区的终端总集。例如,若分流控制器选择在小区覆盖范围下,信号强度较弱的终端作为小区的终端总集,则分流控制器可以获取各个终端的信号强度,并分别与预设信号强度阈值相比较,将各个信号强度小区预设信号强度阈值的终端作为小区的终端总集。
402、分流控制器根据小区的各个终端分别对应的信号质量及传输速率,获取小区的各个终端分别对应的消耗小区功率比。
具体地,步骤402可以为,分流控制器根据公式获取小区的各个终端分别对应的消耗小区功率比。其中,ηk为小区的第k个终端对应的消耗小区功率比,Rk为小区的第k个终端对应的传输速率,CQIk为小区的第k个终端对应的信号质量。例如,终端对应的消耗小区功率比可以为:0.02、0.05、0.035等。
优选地,分流控制器还可以根据公式获取小区的各个终端分别对应的消耗小区功率比。其中,a、b、c、d均为固定值,用于对计算结果进行修正。在本发明实施例中,通过上述公式可以对各个终端分别对应的消耗小区功率比进行调整,从而可以提高各个终端分别对应的消耗小区功率比的精准度,进而可以提高分流终端的选择精准度。
可选地,步骤401可以为,分流控制器获取小区的各个终端分别对应的信号强度及传输速率。此时,步骤402可以为,分流控制器根据小区的各个终端分别对应的信号强度及传输速率,获取小区的各个终端分别对应的消耗小区功率比。
其中,信号强度可以为RSCP(received signal code power,接收信号
码功率)、RSRP(reference signal received power,参考信号接收功率)、RSSI(Received Signal Strength Indicator、接收信号强度指示)等。
具体地,分流控制器可以根据公式获取小区的各个终端分别对应的消耗小区功率比。其中,ηk为小区的第k个终端对应的消耗小区功率比,Rk为小区的第k个终端对应的传输速率,Psk为小区的第k个终端对应的信号强度。
优选地,分流控制器还可以根据公式获取小区的各个终端分别对应的消耗小区功率比。其中,a、b、c、d均为固定值,用于对计算结果进行修正。在本发明实施例中,通过上述公式可以对各个终端分别对应的消耗小区功率比进行调整,从而可以提高各个终端分别对应的消耗小区功率比的精准度,进而可以提高分流终端的选择精准度。
对于本发明实施例,若在步骤401之前,分流控制器确定的小区的终端总集为小区覆盖范围下的所有终端,则在步骤402之后还可以包括:分流控制器选择在小区覆盖范围下,蜂窝网络中优先级较低,或者信号强度较弱,或者信号质量较差,或者传输速率较高,或者业务类型占用流量较大,或者业务类型实时性要求较低的各个终端。
403、分流控制器将小区的各个终端按照分别对应的消耗小区功率比由高到低的顺序进行排序。
对于本发明实施例,通过将各个消耗小区功率比较大的终端配置为小区的各个分流终端,能够减少分流终端的数量。在本发明实施例中,由于分流造成用户体验下降的比例为固定值,因此减少分流终端的数量,可以降低用户体验下降的可能性,进而可以提高用户体验。
可选地,步骤403还可以为,分流控制器将小区的各个终端按照分别对应的消耗小区功率比由低到高的顺序进行排序。在本发明实施例中,通过将各个消耗小区功率比较小的终端配置为小区的各个分流终端,能够将各个对小区负载贡献较小的终端从蜂窝网络分流至无线局域网中。
404、分流控制器将排序之后的各个终端分别对应的消耗小区功率比
进行累加,直至累加之后的消耗小区功率比大于或者等于预置阈值。
可选地,步骤404之前可以包括:分流控制器预先配置预置阈值。例如,预置阈值可以为0.2、0.15、0.3等。在本发明实施例中,预置阈值用于指示小区负载的下降比例。
可替换地,步骤404之前还可以包括:分流控制器首先获取小区的实际负载值与小区的合理负载值,然后根据公式获取小区的预置阈值。其中,γ为小区的预置阈值,Fc为小区的实际负载值,ΔFc为小区的实际负载值与小区的合理负载值的差值。
进一步地,步骤404之前还可以包括:分流控制器首先获取小区的实际负载值、小区的合理负载值及小区对应的各个无线局域网的合理负载值与实际负载值的差值,然后根据公式获取小区的预置阈值。其中,γ为小区的预置阈值,Fc为小区的实际负载值,ΔFc为小区的实际负载值与小区的合理负载值的差值,Δfw为小区对应的各个无线局域网的合理负载值与实际负载值的差值之和。
其中,分流控制器可以通过公式计算小区对应的各个无线局域网的合理负载值与实际负载值的差值之和,Δfw(i)为小区对应的第i个无线局域网的合理负载值与实际负载值的差值,G()为负载转换函数,用于将无线局域网对应的负载值转换至蜂窝网络对应的负载值。在本发明实施例中,G()可以为线性函数、指数函数、幂函数等。
可选地,AC或者AP可以通过公式计算小区对应的各个无线局域网的合理负载值与实际负载值的差值之和,并将小区对应的各个无线局域网的合理负载值与实际负载值的差值之和发送给分流控制器,以使得分流控制器可以根据小区对应的各个无线局域网的合理负载值与实际负载值的差值之和,获取小区的预置阈值。其中,Δfw(i)为小区对应的第i个无线局域网的合理负载值与实际负载值的差值,G()为负载转换函
数,用于将无线局域网对应的负载值转换至蜂窝网络对应的负载值。在本发明实施例中,G()可以为线性函数、指数函数、幂函数等。
其中,小区对应的各个无线局域网是指在该小区的蜂窝网络覆盖的范围下,所覆盖的各个无线局域网。例如图7中,在小区的蜂窝网络覆盖的范围下,所覆盖的无线局域网分别为无线局域网A、无线局域网B、无线局域网C及无线局域网D。
对于本发明实施例,通过综合计算小区的蜂窝网络中超出合理负载值的差值及无线局域网中可容纳负载值的差值,能够实现为蜂窝网络进行分流的同时,保证无线局域网中不出现负载过重的情况。
405、分流控制器将进行累加的各个消耗小区功率比分别对应的终端配置为小区的各个分流终端。
对于本发明实施例,通过将各个消耗小区功率比较大,且之和大于或者等于预置阈值的终端配置为小区的各个分流终端,能够实现按照预置阈值下降蜂窝网络的负载值,并减少分流终端的数量。在本发明实施例中,由于分流造成用户体验下降的比例为固定值,因此减少分流终端的数量,可以降低用户体验下降的可能性,进而可以提高用户体验。
