其中,UE的RSSI可以从WLAN和蜂窝技术网络融合通信***中的UE报告配置的WLAN会议阈值中提取;例如,可以提取WLAN中的BEACON的RSSI信息;或者提取WLAN中的UE的REQUEST的RSSI信息;或者将WLAN中的UE的BEACON内的RSSI信息和WLAN中的UE的REQUEST内的RSSI信息提取后进行综合,并求取均衡值。
在实现过程中,由于RSSI变化速率为单位时间内RSSI的前后变化量的绝对值。因此,当检测到UE的RSSI在T秒内从R1变化为R2时,所述UE的RSSI的变化速率L的可以通过下式求取:
示例性地,为了增加测量的准确性以及避免频繁选择传输链路,所述终端的RSSI变化速率L的统计值可以不基于单次RSSI测量。例如,所述R1和R2均可以为多次统计后的均值,比如,RSSI变化前取u组RSSI值:U0,U1,…Uu;RSSI变化后取V组RSSI值:V0,V1,…Vv;可以得知:

示例性地,对于UE的通知途径可以通过当前时刻UE所使用的传输链路进行。例如,如果UE当前是默认初始化状态,则通过默认初始化的LTE网络链路进行通知;如果UE当前为非默认状态,则采用当前UE的传输链路进行通知;
与此同时,基于分流锚点处于eNodeB的PDCP层考虑,可以在PDCP层将UE数据接入到eNodeB协议层后并发送给终端。
S312:通知UE下一时刻使用WLAN网络接入融合网络;并调度网络侧用WLAN链路传输UE的数据流。
示例性地,同步骤S310,对于UE的通知途径可以通过当前时刻UE所使用的传输链路进行;
与此同时,基于分流锚点在eNodeB的PDCP层考虑,可以在PDCP层将UE数据通过GTP-U,并使用UDP发送到WT,即分流到Xw接口的PDCP PDU。

S403:实时检测接入UE的锁定位置的偏移变化状态。
示例性地,所述锁定位置的偏移变化状态用所述接入UE的锁定位置的相对变化速率来衡量。其中,接入UE的锁定位置的相对变化速率为单位时间内所述接入UE的锁定位置的前后变化量的绝对值。示例性地,对于WLAN和5G网络融合,接入UE的锁定位置监控可通过移动边缘计算(MEC,Mobile Edge Computing)获得。
S404:对接入UE的锁定位置的偏移变化速率进行计算。

示例性地,为避免频繁切换选择5G网络或WLAN传输链路以及基于准确性考虑,所述相对变化速率基于锁定位置变化状态统计值而不是单次锁定位置。举例来说,所述L1和L2均为多次统计后取其均值;比如,初次锁定位置取e组锁定位置值U0,U1,…,Ue,变化后锁定位置取f组锁定位置值,V0,V1,…,Vf,则
在实现过程中,对于WLAN和5G网络融合网络,U0,U1,…,Ue和V0,V1,…,Vf,可以通过MEC计算获得。
S405:将当前锁定位置的偏移变化速率值Y与预置的参照值H进行比较:如果Y大于H,则转至步骤S406;否则,转至步骤S407。

示例性地,对于接入UE的通知途径可以通过当前时刻UE使用的传输链路进行。例如,如若UE当前是默认初始化状态,则通过默认设置的5G网络链路进行通知;如若UE当前为非默认状态,则采用接入UE当前接入链路进行通知。
与此同时,基于响应和传输速率考虑,可以调度网络侧下一时刻使用接入UE所对应的5G技术网络中对应的边缘节点链路来传输所述接入UE的数据流。
S407:传输链路调度模块调度网络侧下一时刻用WLAN链路传输接入UE的数据流,调度网络侧下一时刻用WLAN链路传输接入UE的数据流。
示例性地,对于接入UE的通知途径可以通过当前时刻UE使用的传输链路进行。例如,如若UE当前是默认初始化状态,则通过默认设置的5G网络链路进行通知;如若UE当前为非默认状态,则采用接入UE当前接入链路进行通知。

接入UE的锁定位置的偏移变化监控模块30,配置为实时检测接入UE的锁定位置的偏移变化状态。示例性地,所述锁定位置的偏移变化状态用所述接入UE的锁定位置的相对变化速率来衡量。其中,接入UE的锁定位置的相对变化速率为单位时间内所述接入UE的锁定位置的前后变化量的绝对值。示例性地,对于WLAN和5G网络融合,接入UE的锁定位置监控可通过MEC(Mobile Edge Computing,MEC,移动边缘计算)计算获得。
锁定位置的偏移变化速率计算模块40,配置为对接入UE的锁定位置的偏移相对变化速率进行计算。其中,锁定位置的偏移相对变化速率为单位时间内锁定位置的前后偏移变化量的绝对值。
示例性地,为避免频繁切换选择5G网络或WLAN传输链路以及基于准确性考虑,所述相对变化速率基于锁定位置变化状态统计值而不是单次锁定位置。
传输链路通知模块50,配置为通知接入UE在下一时刻用5G技术网络链路传输还是WLAN链路传输。其中,通知依据所述锁定位置的偏移变化速率计算模块40的计算结果进行,如果所述锁定位置的偏移变化速率计算模块40的计算结果高于所述预置模块20设置的接入UE的锁定位置的偏移变化速率的参照值,通知接入UE下一时刻用5G技术网络链路传输;如果所述锁定位置的偏移变化速率计算模块40的计算结果不高于所述预置模块20设置的接入UE的锁定位置的偏移变化速率的参照值,通知接入UE下一时刻用WLAN链路传输。

通过本实施例,融合通信分流初始化模块10对预置模块20、接入UE的锁定位置的偏移变化监控模块30、锁定位置的偏移变化速率计算模块40、传输链路通知模块50以及传输链路调度模块70进行上电和初始化配置;预置模块20预置接入UE的锁定位置的偏移变化速率的参照值;接入UE的锁定位置的偏移变化监控模块30实时检测接入UE的锁定位置的偏移变化状态;锁定位置的偏移变化速率计算模块40对接入UE的锁定位置的偏移变化速率
进行计算;传输链路通知模块50根据锁定位置的偏移变化速率计算模块40计算获得的接入UE的锁定位置的偏移变化速率值和预置模块20预置接入UE的锁定位置的偏移变化速率的参照值相比较,如果所述锁定位置的偏移变化速率计算模块40计算获得的接入UE的锁定位置的偏移变化速率值高于预置模块20预置接入UE的锁定位置的偏移变化速率的参照值,通知传输链路调度模块70调度网络侧下一时刻用5G技术网络链路传输接入UE的数据流;如果所述锁定位置的偏移变化速率计算模块40计算获得的接入UE的锁定位置的偏移变化速率值不高于预置模块20预置接入UE的锁定位置的偏移变化速率的参照值,通知传输链路调度模块70调度网络侧下一时刻用WLAN网络链路传输接入UE的数据流。如此,既充分发挥了5G网络覆盖能力强的优点又发挥了WLAN容量大的优点来实现动态的数据分流。
