参见图 3 , 本实施例提供了一种控制传输模式的方法, 包括:
301 : 接收基站下发的门限值;
其中, 所述门限值可以为速率门限值, 或者也可以为功率门限值, 本实施 例对此不做具体限定。

确定在蜂窝网模式下传输当前上行业务所需的速率;
确定在蜂窝网模式下以该速率传输当前上行业务所需的第一发射功率; 估计在 WiFi模式下以该速率传输当前上行业务所需的第二发射功率; 如果该第二发射功率比该第一发射功率小且二者的差值不低于门限值, 则 确定该 WiFi接入点能够提供的速率满足当前上行业务所需的速率。
本实施例提供的上述方法具体地可以由 UE来执行。
本实施例提供的上述方法, 通过根据接收的门限值判断 WiFi接入点能够 提供的速率是否满足当前上行业务所需的速率, 如果确定满足, 则使用 WiFi 模式传输当前上行业务, 如果确定不满足, 则使用蜂窝网模式和 WiFi模式传 输当前上行业务, 在本地实现了对传输模式的控制, 其中, 使用 WiFi模式传 输时, 不仅能够节省 UE的电能, 并且也为 UE提供了更好的速率传输, 确保 了 UE的服务质量。 实施例 3
参见图 4, 本实施例提供了一种控制传输模式的方法, 包括:
401 : 向 WiFi接入点询问它能够承载的最大上行速率;
402: 接收 WiFi接入点返回的它能够承载的最大上行速率;
403: 判断 UE当前上行业务所需的速率是否小于等于所述 WiFi接入点能 够承载的最大上行速率;
404: 如果是, 则确定 UE的传输模式为 WiFi模式, 通知所述 UE停止蜂 窝网模式传输当前上行业务, 保留 WiFi模式传输当前上行业务。
本实施例中, 如果上述判断的结果为否, 则可以保持 UE目前的传输模式 不变, 即仍然使用原有的传输模式进行传输。
具体地, 步骤 403可以包括:
获取所述 UE当前上行业务在蜂窝网模式下的上行速率与在 WiFi模式下 的上行速率;
判断所述 UE当前上行业务在蜂窝网模式下的上行速率与在 WiFi模式下 的上行速率之和是否小于等于所述 WiFi接入点能够承载的最大速率。
其中, 基站可以向核心网侧的流量控制单元获取 UE当前上行业务在蜂窝 网模式下的上行速率及在 WiFi模式下的上行速率, 或者, 基站也可以通知 UE 上报其在蜂窝网模式和 WiFi模式下各自的上行速率, 本实施例对此不做具体 限定。
例如, UE当前上行业务在蜂窝网模式下的上行速率为 Rl , UE当前上行 业务在 WiFi模式下的上行速率为 R2, WiFi接入点能够承载的最大速率为 R— WiFi— Up— Max, 则上述判断步骤中的条件可以表示为如下公式:
Rl + R2 < R— WiFi— Up— Max ( 1 )
只有当上述公式(1 ) 中的条件满足时, 才确定 WiFi接入点能够提供的速 率满足当前业务所需的速率, 因此, 可以通知 UE停止蜂窝网模式传输当前上 行业务,保留 WiFi模式传输当前上行业务。如果 UE原来采用 LTE模式和 WiFi 模式两种模式同时传输, 则 eNB可以通知 UE把 LTE模式当前所发送的上行 速率调整到 WiFi上发送。从而, 保证了在 WiFi环境足够好的时候,仅由 WiFi 提供传输即可, 无需 UE同时在 WiFi和 LTE中传输, 不仅能够为 UE节电, 而且也能提升 UE的 QoS ( Quality of Service, 服务质量)。
本实施例提供的上述方法具体地可以由基站来执行。
本实施例提供的上述方法, 通过判断 UE当前上行业务所需的速率是否小 于等于 WiFi接入点能够承载的最大上行速率, 如果是, 则通知所述 UE停止 蜂窝网模式传输当前上行业务, 保留 WiFi模式传输当前上行业务, 对 UE的 传输模式给出的具体的指导, 提供了可靠的解决方案, 实现了 UE传输模式的 可控性, 其中, 控制 UE在 WiFi模式下传输, 不仅能够节省 UE的电能, 并且 也为 UE提供了更好的速率传输, 确保了 UE的服务质量。 实施例 4
参见图 5, 本实施例提供了一种控制传输模式的方法, 包括:
501 : 确定蜂窝网传输当前下行业务所需的速率;
502: 询问 WiFi接入点以所述速率传输当前下行业务所需的发射功率;
503: 接收 WiFi接入点返回的以所述速率传输当前下行业务所需的发射功
504: 判断 WiFi接入点以所述速率传输当前下行业务所需的发射功率, 是 否比蜂窝网以所述速率传输当前下行业务所需的发射功率小, 且二者的差值不 低于预设的门限值;
505: 如果是, 则确定 UE的传输模式为 WiFi模式, 通知 UE使用 WiFi 模式传输当前下行业务。
本实施例中, 如果上述判断的结果为否, 则可以保持 UE目前的传输模式 不变, 即仍然使用原有的传输模式进行传输。
本实施方式中, 所述门限值可以为基站预先设置的大于零的数, 具体数值 可以根据需要设置, 本实施例对此不做具体限定。
例如,蜂窝网传输当前下行业务所需的速率为 R, WiFi接入点以所述速率 R传输当前下行业务所需的发射功率为 PI— down,蜂窝网以所述速率 R传输当 前下行业务所需的发射功率为 P2— down, 则上述判断步骤中的条件可以表示为 如下公式:
Pl down < P2_down - ΔΡ— down ( 2 )
其中, ΔΡ— down为基站预先设置的大于零的参数, PI— down为 WiFi接入 点预先配置的, P2— down为基站预先配置的。
当上述公式(2 ) 中的条件满足时, 可以确定在 WiFi接入点的下行发射功 率能够满足当前业务的需要, 而且能够给网络带来节电特性, 因此, 可以将网 络侧的下行发射功率调整为全部都通过 WiFi接入点来传输, 并通知 UE使用 WiFi模式接收当前下行业务, 从而能够为 UE节电, 且业务的传输速率较高, UE的服务质量也有可靠的保证。
其中, 基站可以通知核心网让下行数据流从 CN分流到 WiFi AP, 或者也 可以从基站直接分流到 WiFi AP, 具体的场景不限定。
本实施例提供的上述方法具体地可以由基站来执行。
本实施例提供的上述方法, 通过判断 WiFi接入点以所述速率传输当前下 行业务所需的发射功率, 是否比蜂窝网以所述速率传输当前下行业务所需的发 射功率小, 且二者的差值不低于预设的门限值, 如果是, 则通知 UE使用 WiFi 模式传输当前下行业务, 对 UE的传输模式给出的具体的指导, 提供了可靠的 解决方案,实现了 UE传输模式的可控性,其中,控制 UE在 WiFi模式下传输, 不仅能够节省 UE的电能, 并且也为 UE提供了更好的速率传输, 确保了 UE 的服务质量。 实施例 5
参见图 6, 本实施例提供了一种控制传输模式的方法, 包括:
601 : 确定 UE当前上行业务所需的速率;
具体地, 可以由 UE上报当前上行业务所需的速率给基站。
602: 向 WiFi接入点询问它能够承载的最大上行速率;
603: 接收 WiFi接入点返回的它能够承载的最大上行速率;
604: 判断 UE当前上行业务所需的速率是否超过 WiFi接入点能够承载的 最大上行速率与蜂窝网能够承载的最大上行速率之和;
605: 如果是, 则确定 WiFi接入点能够提供的速率不满足当前上行业务所 需的速率, 确定 UE的传输模式为蜂窝网模式和 WiFi模式,通知 UE使用蜂窝 网模式和 WiFi模式传输当前上行业务。
具体地, 基站可以通知 UE在 WiFi模式下发送当前上行业务的上行速率 为 WiFi接入点能够承载的最大上行速率, 在蜂窝网模式下发送当前上行业务 的上行速率为 UE当前上行业务所需的速率与蜂窝网能够承载的最大上行速率 的差。
本实施例中, 如果上述判断的结果为否, 则可以保持 UE目前的传输模式 不变, 即仍然使用原有的传输模式进行传输。
例如, UE当前上行业务所需的速率为 R— Up, WiFi接入点能够承载的最 大上行速率为 R— WiFi— Up— Max , 蜂窝网能够承载的最大上行速率为 R— L— Up— Max , 则上述判断步骤中的条件可以表示为如下公式:
R— Up > R— L— Up— Max+R— WiFi— Up— Max ( 3 ) 当上述公式(3 ) 中的条件满足时, 可以确定 WiFi接入点能够提供的速率 不满足当前上行业务所需的速率, 因此, 需要 UE在两种模式下进行传输, 可 以将通知 UE 采用蜂窝网模式和 WiFi模式, 且蜂窝网模式下的上行速率为 R— L— Up— Max , WiFi模式下的上行速率为 R— WiFi— Up— Max。 通常, WiFi会提 供更高的速率传输, 所以在 WiFi不能提供的速率之外, 再辅助让蜂窝网来提 供速率传输, 从而, 先确保 WiFi模式下尽可能为 UE传输数据, 在 WiFi接入 点提供的速率不能满足需求的情况下, 再通过蜂窝网提供相应的速率进行传 输。
本实施例提供的上述方法具体地可以由基站来执行。
本实施例提供的上述方法, 通过判断 UE当前上行业务所需的速率是否超 过 WiFi接入点能够承载的最大上行速率与蜂窝网能够承载的最大上行速率之 和, 如果是, 则通知 UE使用 WiFi模式传输当前上行业务, 对 UE的传输模式 给出的具体的指导, 提供了可靠的解决方案, 实现了 UE传输模式的可控性, 其中, 控制 UE在 WiFi模式下传输, 不仅能够节省 UE的电能, 并且也为 UE 提供了更好的速率传输, 确保了 UE的服务质量。 实施例 6
参见图 7, 本实施例提供了一种控制传输模式的方法, 包括:
701 : 确定当前下行业务所需的速率;
702: 判断所述当前下行业务所需的速率是否既大于蜂窝网能够发送的最 大下行速率又大于 WiFi接入点能够发送的最大下行速率;
其中, 基站可以询问 WiFi接入点能够发送的最大下行速率, 并接收 WiFi 接入点返回的其能够发送的最大下行速率。
703 : 如果是, 则确定 WiFi接入点能够提供的速率不满足当前下行业务所 需的速率, 确定 UE的传输模式为蜂窝网模式和 WiFi模式, 通知 UE在 WiFi 模式下接收下行业务的速率为所述 WiFi接入点能够发送的最大下行速率, 在 蜂窝网模式下接收下行业务的速率为所述当前下行业务所需的速率与所述 WiFi接入点能够发送的最大下行速率的差。
本实施例中, 当上述判断的结果为是时, 可以确定所述 WiFi接入点能够 提供的速率不满足当前下行业务所需的速率, 因此, 通知 UE采用两种模式进 行传输。 当上述判断的结果为否时, 可以保持 UE目前的传输模式不变, 即仍 然使用原有的传输模式进行传输。
例如, 当前下行业务所需的速率为 R— Down, 蜂窝网能够发送的最大下行 速率为 R—L— Down— Max , WiFi 接入点能够发送的最大下行速率为 R— WiFi— Down— Max, 则上述判断步骤中的条件可以表示为如下公式:
R— Down > R—L— Down— Max; 且
R— Down > R— WiFi— Down— Max; ( 4 )
其中, 当上述公式(4 ) 满足时, 基站可以通知 UE在 WiFi模式下接收下 行业务的速率为 R— WiFi— Down— Max, 在蜂窝网模式下接收下行业务的速率为 R— Down- R— WiFi— Down— Max, 从而控制 UE采用两种模式进行传输。 进一步 地, 还可以通知 WiFi接入点以速率 R WiFi Down Max向 UE发送下行业务, 如果 UE原有的传输模式为蜂窝网模式, 则可以从基站直接分流到 WiFi AP, 或者从核心网分流到连接 WiFi AP的网管, 从而保证 UE使用两种模式传输。
本实施例提供的上述方法具体地可以由基站来执行。
本实施例提供的上述方法,通过判断 U当前下行业务所需的速率是否既大 于蜂窝网能够发送的最大下行速率又大于 WiFi接入点能够发送的最大下行速 率, 如果是, 则通知 UE在 WiFi模式下接收下行业务的速率为所述 WiFi接入 点能够发送的最大下行速率,在蜂窝网模式下接收下行业务的速率为所述当前 下行业务所需的速率与所述 WiFi接入点能够发送的最大下行速率的差,对 UE 的传输模式给出的具体的指导, 提供了可靠的解决方案, 实现了 UE传输模式 的可控性, 在 WiFi模式无法保证速率的情况下, 采用两种模式进行传输, 为 UE的服务质量提供了可靠的保证。 实施例 7
参见图 8, 本实施例提供了一种控制传输模式的方法, 包括:
801 : 接收基站下发的门限值;
具体地, 基站可以通过配置测量参数来下发该门限值。 本实施例中, 该门 限值为发射功率门限值。
802: 确定在蜂窝网模式下传输当前上行业务所需的速率;
803: 确定在蜂窝网模式下以所述速率传输当前上行业务所需的第一发射 功率;
具体地, UE可以根据当前上行业务所需的速率计算出所述第一发射功率, 如根据香农公式: R=B*log ( 1+SNR ) 以及 SNR=P*G/ ( I+N )就可以计算出第 一发射功率 P; 其中, R代表当前上行业务所需的速率, B是分配的上行带宽, SNR是 UE的信噪比或者信干燥比, G为大尺度衰落, I是干扰 interference, N是噪声, 具体计算过程, 此处不做过多说明。
804: 估计在 WiFi模式下以所述速率传输当前上行业务所需的第二发射功 率;
805: 判断是否所述第二发射功率比所述第一发射功率小且二者的差值不 低于该门限值, 如果是, 则执行 806; 否则, 执行 807;
806: 使用 WiFi模式传输当前上行业务, 流程结束;
这种情况下, 可以确定 WiFi接入点能够提供的速率满足当前上行业务所 需的速率, 因此, 可以仅采用 WiFi模式传输当前上行业务。 进一步地, UE还 可以通知基站将采用 WiFi模式进行传输, 从而基站可以释放分配给该 UE的 资源, 节省了宝贵的资源。
807: 使用蜂窝网模式和 WiFi模式传输当前上行业务, 流程结束。
这种情况下, 可以确定 WiFi接入点能够提供的速率不满足当前上行业务 所需的速率, 因此, 可以需要同时采用 WiFi模式和蜂窝网模式传输当前上行 业务。
例如, UE在蜂窝网模式下传输当前上行业务所需的速率为 R— Up,在蜂窝 网模式下以所述速率 R— Up传输当前上行业务所需的第一发射功率为 PI— up, 在 WiFi模式下以所述速率 R— Up传输当前上行业务所需的第二发射功率为 P2— up , 则上述判断步骤中的条件可以表示为如下公式:
P2_up < Pl_up - ΔΡ— up ( 5 )
其中, ΔΡ— up就是所述门限值, 是一个大于零的参数, 可以由基站预先配 置给 UE, 本实施例对具体数值不做限定。 当上述公式(5 )满足时, 可以确定 WiFi接入点能够提供的速率满足当前上行业务所需的速率, 因此, 可以采用 WiFi模式传输当前上行业务, 而且在 Wifi模式下传输 UE更省电, 传输速率 也较高, 服务质量得到了可靠的保证。
本实施例提供的上述方法具体地可以由 UE来执行。
本实施例提供的上述方法, 通过判断是否所述第二发射功率比所述第一发 射功率小且二者的差值不低于基站下发的门限值, 如果是, 则使用 WiFi模式 传输当前上行业务, 否则, 使用蜂窝网模式和 WiFi模式传输当前上行业务, 在本地实现了对传输模式的控制, 其中, 使用 WiFi模式传输时, 不仅能够节 省 UE的电能, 并且也为 UE提供了更好的速率传输, 确保了 UE的服务质量。 进一步地, 如果是在部分 LTE频段同 WiFi产生共存干扰的场景下, 通过上述 方法控制 UE采用 WiFi模式传输, 还可以有效地规避两种模式相互之间的干 扰。 实施例 8
