具体实施方式
本发明实施例提供了一种信号传输方法及系统、控制器， 能够实现两个共 频带的信号同时工作时， 共享一个天线。
需要说明的是，本发明所有实施例均适用于在第一信号和第二信号共频带 且需要同时工作的双卡双待双通的应用场景中。
请参照图 1 , 第一信号和第二信号同时工作并共用一个天线， 该第一信号 和该第二信号为共频带，射频前端包括该天线， 该天线用于收发该第一信号和 该第二信号的混合信号， 本发明实施例中信号传输方法一个实施例包括：
101、 控制器确定该第一信号的优先级高于该第二信号的优先级； 本实施例中，控制器可以确定该第一信号的优先级高于该第二信号的优先 级，在实际应用中，控制器可以根据该控制器所在的终端的业务导向来确定两 个信号之间的优先级， 例如， 中国移动通信集团 （CMCC , China Mobile Communications Corporation )的 SGLTE方案中 GSM信号和 LTE信号共频带， 如果控制器所在的终端为手机， 由于手机的业务导向为语音通话， 则控制器可 以确定 GSM信号的优先级高于 LTE信号的优先级；如果控制器所在的终端为 平板电脑， 由于平板电脑的业务导向为数据传输， 则控制器可以确定 LTE信 号的优先级高于 GSM信号的优先级， 在实际应用中， 控制器还可以根据用户 使用的频率确定两个信号的优先级， 例如， 双卡双待双通方案中 GSM信号和 宽带码分多址（ WCDMA, Wideband Code Division Multiple Access )信号共频 带， 如果用户使用 GSM 次数多， 则控制器确定 GSM 信号的优先级高于 WCDMA信号的优先级， 如果控制器所在终端本身是某一运营商的定制终端， 如果该运营商使用的是 GSM制式， 则控制器可以确定 GSM信号的优先级高 于 WCDMA信号的优先级， 此处如何确定两个信号的优先级不做限定。
需要说明的是，射频前端至少包括一个天线，当然还可以包括其他的元件， 如天线的收发开关， 信号放大器等。
102、 当第一信号和第二信号同时工作时， 判断优先级高的该第一信号的 信号状态是否满足业务需求， 若不满足业务需求， 则执行步骤 103, 若满足业 务需求， 则执行步骤 104;
本实施例中， 当第一信号和第二信号同时工作时，控制器判断优先级高的 第一信号的信号状态是否满足业务需求， 在实际应用中， 若第一信号为 GSM 信号， 控制器可以判断 GSM信号的信号状态是否满足语音通话的需求， 若第 一信号为 LTE信号， 则控制器可以判断 LTE信号的信号状态是否满足数据传 输的需求。 103、 将该天线接收到的该第一信号和该第二信号的混合信号通过单刀双 掷开关引导至第一信号的处理后端；
本实施例中， 当优先级高的第一信号的信号状态不满足业务需求时，控制 器可以将天线收到的该第一信号和该第二信号的混合信号通过单刀双掷开关 引导至第一信号的处理后端， 在实际应用中，通过单刀双掷开关将天线收到的 该第一信号和该第二信号的混合信号引导至第一信号的处理后端，此时天线接 收到的混合信号只能在第一信号所在的信道使用，这样第一信号的信号状态就 能够满足业务需求。
104、 将该天线接收到的该第一信号和该第二信号的混合信号通过该单刀 双掷开关引导至功分器，并通过该功分器分别将该第一信号和该第二信号的混 合信号分别传递至该第一信号的处理后端和第二信号的处理后端。
本实施例中， 当优先级高的第一信号的信号状态满足业务需求时，控制器 可以将该天线接收到的该第一信号和该第二信号的混合信号通过该单刀双掷 开关引导至功分器，并通过该功分器分别将该第一信号和该第二信号的混合信 号分别传递至该第一信号的处理后端和第二信号的处理后端， 在实际应用中， 功分器是功率分配器，是一种将一路输入信号能量分成两路或多路输出相等或 不相等能量的器件，也可反过来将多路信号能量合成一路输出， 由于本发明实 施例为两个信号， 所以使用的是一分二功分器， 这样就可以将混合信号同时分 享给第一信号和第二信号所在的信道中。
本实施例中，控制器通过判断优先级高的第一信号的信号状态是否满足业 务需求来控制单刀双掷开关： 若不满足业务需求，将天线接收到的第一信号和 第二信号的混合信号通过单刀双掷开关引导至第一信号的处理后端；若满足业 务需求，则将天线接收到的第一信号和第二信号的混合信号通过单刀双掷开关 引导至功分器，并通过功分器分别将第一信号和第二信号的混合信号分别传递 至第一信号的处理后端和第二信号的处理后端，这样能够实现两个共频带的信 号同时工作时， 共享一个天线， 并且能够保证优先级高的信号的业务需求， 提 高用户的体验。
为便于理解， 下面以一具体实例对本发明实施例中信号传输方法进行描 述， 请参阅图 2, 本发明实施例中信号传输方法另一实施例， 第一信号和第二 信号同时工作并共用一个天线， 该第一信号和该第二信号为共频带，射频前端 包括该天线， 该天线用于收发该第一信号和该第二信号的混合信号， 该方法包 括：
201、 控制器确定该第一信号的优先级高于该第二信号的优先级； 本实施例中，控制器可以确定该第一信号的优先级高于该第二信号的优先 级，在实际应用中，控制器可以根据该控制器所在的终端的业务导向来确定两 个信号之间的优先级， 例如， CMCC的 SGLTE方案中 GSM信号和 LTE信号 共频带， 如果控制器所在的终端为手机， 由于手机的业务导向为语音通话， 则 控制器可以确定 GSM信号的优先级高于 LTE信号的优先级；如果控制器所在 的终端为平板电脑， 由于平板电脑的业务导向为数据传输， 则控制器可以确定 LTE信号的优先级高于 GSM信号的优先级， 在实际应用中， 控制器还可以根 据用户使用的频率确定两个信号的优先级， 例如， SGLTE方案中 GSM信号和 时分同步的码分多址（TDSCDMA, Time Division-Synchronous Code Division Multiple Access )信号共频带，如果用户使用 GSM频率高，则控制器确定 GSM 信号的优先级高于 TDSCDMA信号的优先级， 此处如何确定两个信号的优先 级不做限定。
本实施例以 CMCC的 SGLTE方案中 GSM信号和 LTE信号共频带，控制器所 在的终端为手机为例进行说明， 此时第一信号为 GSM信号， 第二信号为 LTE信 号， GSM信号的优先级高于 LTE信号的优先级。
202、 判断该第一信号是否处于接收时隙， 且该第一信号的接收信号强度 是否小于第一门限值和 /或该第一信号的发送信号强度是否大于第二门限值；
203、 若该第一信号的接收信号强度小于该第一门限值和 /或该第一信号的 发送信号强度大于该第二门限值，且该第一信号处于接收时隙， 则确定优先级 高的该第一信号的信号状态不满足该业务需求；
204、 若该第一信号的接收信号强度大于或者等于该第一门限值和 /或该第 一信号的发送信号强度小于或者等于该第二门限值，或者该第一信号没有处于 接收时隙， 则确定优先级高的该第一信号的信号状态满足该业务需求；
本实施例中， 若该第一信号的接收信号强度小于该第一门限值和 /或该第 一信号的发送信号强度大于该第二门限值， 且该第一信号处于接收时隙， 则确 定优先级高的该第一信号的信号状态不满足该业务需求， 然后执行步骤 205 , 满足以下三种条件中任一种条件就能够确定优先级高的该第一信号的信号状 态不满足该业务需求：
A.第一信号处于接收时隙，且第一信号的接收信号强度小于该第一门限值 或者第一信号的发送信号强度大于该第二门限值；
B.第一信号处于接收时隙，且第一信号的接收信号强度小于该第一门限值 和第一信号的发送信号强度大于该第二门限值。
若该第一信号的接收信号强度大于或者等于该第一门限值和 /或该第一信 号的发送信号强度小于或者等于该第二门限值，或者该第一信号没有处于接收 时隙， 则确定优先级高的该第一信号的信号状态满足该业务需求， 然后执行步 骤 206, 根据该判断方法只要满足下面任一种条件就能够确定优先级高的该第 一信号的信号状态满足该业务需求：
A.第一信号的接收信号强度大于或者等于该第一门限值，以及第一信号的 接收信号强度小于或者等于该第二门限值；
B.第一信号的接收信号强度大于或者等于该第一门限值；
C.第一信号的发送信号强度小于或者等于该第二门限值；
D.第一信号没有处于接收时隙。
需要说明的是， 当第一信号没有处于接收时隙时， 其实是没有接收第一信 号， 本实施例中是视为优先级高的该第一信号的信号状态满足该业务需求。
例如， 本实施例中对 GSM信号进行判断， 判断 GSM信号是否处于接收 时隙，且 GSM信号的接收信号强度是否小于第一门限值和 /或该第一信号的发 送信号强度是否大于第二门限值， 这里的第一门限值可以取 -103dBm, 第二门 限值可以取 22dBm。 在实际应用中， 第一门限值和第二门限值的取值不做限 定。
205、 通过逻辑控制接口输出的第一电压控制该单刀双掷开关的第一端导 通；
206、 通过逻辑控制接口输出的第二电压控制该单刀双掷开关的第二端导 通；
本实施例中， 若优先级高的该第一信号的信号状态不满足该业务需求， 则 控制器通过逻辑控制接口输出的第一电压控制该单刀双掷开关的第一端导通， 若优先级高的该第一信号的信号状态满足该业务需求，则控制器通过逻辑控制 接口输出的第二电压控制该单刀双掷开关的第二端导通，在实际应用中，在单 刀双掷开关上设置一个逻辑控制接口，控制器可以通过逻辑控制接口输出两种 电压， 一种是高电压， 一种是低电压， 若第一电压为高电压时， 则第二电压为 低电压； 若第一电压为低电压时， 则第二电压为高电压， 控制器可以通过逻辑 控制接口输出的电压的高低来控制单刀双掷开关导通端点。
207、 将该天线接收到的该第一信号和该第二信号的混合信号通过单刀双 掷开关引导至第一信号的处理后端；
本实施例中，在步骤 205之后，控制器可以将天线收到的该第一信号和该 第二信号的混合信号通过单刀双掷开关引导至第一信号的处理后端，在实际应 用中，通过单刀双掷开关将天线收到的该第一信号和该第二信号的混合信号引 导至第一信号的处理后端，此时天线接收到的混合信号只能供给第一信号的处 理后端， 这样第一信号的信号状态就能够满足业务需求。
例如，本实施例中将天线接收到的 GSM信号和 LTE信号的混合信号通过 单刀双掷开关引导至 GSM信号的处理后端。
208、 将该天线接收到的该第一信号和该第二信号的混合信号通过该单刀 双掷开关引导至功分器，并通过该功分器将该第一信号和该第二信号的混合信 号分别传递至该第一信号的处理后端和第二信号的处理后端。
本实施例中，在步骤 206之后，控制器可以将该天线接收到的该第一信号 和该第二信号的混合信号通过该单刀双掷开关引导至功分器，并通过该功分器 分别将该第一信号和该第二信号的混合信号分别传递至该第一信号的处理后 端和第二信号的处理后端， 在实际应用中， 功分器是功率分配器， 是一种将一 路输入信号能量分成两路或多路输出相等或不相等能量的器件，也可反过来将 多路信号能量合成一路输出， 由于本发明实施例为两个信号， 所以使用的是一 分二功分器，这样就可以将混合信号同时分享给第一信号的处理后端和第二信 号的处理后端中。
例如，本实施例中将天线接收到的 GSM信号和 LTE信号的混合信号通过 单刀双掷开关引导至功分器，然后在经由功分器将 GSM信号和 LTE信号的混 合信号分别传递至 GSM信号的处理后端和 LTE信号的处理后端。
需要说明的是，第一信号的处理后端主要用于只保留第一信号和第二信号 的混合信号中第一信号，第二信号的处理后端主要用于只保留第一信号和第二 信号的混合信号中第二信号， 在实际应用中， 第一信号的处理后端或第二信号 的处理后端不止用于信号过滤的操作，本领域技术人员还可以通过第一信号的 处理后端或第二信号的处理后端对第一信号或者第二信号进行其他的处理，例 如， 去噪或者放大等， 此处不做限定。
本实施例中，控制器通过判断第一信号是否处于接收时隙且优先级高的该 第一信号的接收信号强度是否小于第一门限值或者该第一信号的发送信号强 度是否大于第二门限值来控制单刀双掷开关： 若不满足该业务需求，将该天线 接收到的该第一信号和该第二信号的混合信号通过单刀双掷开关引导至第一 信号的处理后端； 若满足该业务需求， 则将该天线接收到的该第一信号和该第 二信号的混合信号通过该单刀双掷开关引导至功分器，并通过该功分器分别将 该第一信号和该第二信号的混合信号分别传递至该第一信号的处理后端和第 二信号的处理后端， 这样能够实现两个共频带的信号同时工作时，共享一个天 线， 并且能够保证优先级高的信号的业务需求， 提高用户的体验。
下面以一具体实例对本发明实施例中信号传输方法进行描述，请参阅图 3 , 本发明实施例中信号传输方法另一实施例，第一信号和第二信号同时工作并共 用一个天线， 该第一信号和该第二信号为共频带， 射频前端包括该天线， 该天 线用于收发该第一信号和该第二信号的混合信号， 该方法包括：
301、 控制器确定该第一信号的优先级高于该第二信号的优先级； 本实施例中，控制器可以确定该第一信号的优先级高于该第二信号的优先 级，在实际应用中，控制器可以根据该控制器所在的终端的业务导向来确定两 个信号之间的优先级， 例如， CMCC的 SGLTE方案中 GSM信号和 LTE信号 共频带， 如果控制器所在的终端为手机， 由于手机的业务导向为语音通话， 则 控制器可以确定 GSM信号的优先级高于 LTE信号的优先级；如果控制器所在 的终端为平板电脑， 由于平板电脑的业务导向为数据传输， 则控制器可以确定 LTE信号的优先级高于 GSM信号的优先级， 在实际应用中， 控制器还可以根 据用户使用的频率确定两个信号的优先级， 例如， 双卡双待双通方案中 GSM 信号和 WCDMA信号共频带，如果用户使用 GSM频率高，则控制器确定 GSM 信号的优先级高于 WCDMA信号的优先级， 此处如何确定两个信号的优先级 不做限定。
302、 判断该第一信号的接收信号强度是否小于第一门限值和 /或该第一信 号的发送信号强度是否大于第二门限值；
303、 若该第一信号的接收信号强度小于第一门限值和 /或该第一信号的发 送信号强度大于第二门限值，则确定优先级高的该第一信号的信号状态不满足 该业务需求；
304、 若该第一信号的接收信号强度大于或者等于第一门限值和 /或该第一 信号的发送信号强度小于或者等于第二门限值，则确定优先级高的该第一信号 的信号状态满足该业务需求；
本实施例中，控制器可以判断第一信号的接收信号强度是否小于第一门限 值和 /或该第一信号的发送信号强度是否大于第二门限值， 若该第一信号的接 收信号强度小于第一门限值和 /或该第一信号的发送信号强度小于第一门限 值， 则确定优先级高的该第一信号的信号状态不满足该业务需求， 然后执行步 骤 305; 若该第一信号的接收信号强度大于或者等于第一门限值和 /或该第一信 号的发送信号强度小于或者等于第二门限值，则确定优先级高的该第一信号的 信号状态满足该业务需求， 然后执行步骤 306。
步骤 305到步骤 308与第二实施例中步骤 205到步骤 208相同， 此处不再赘 述。
下面对用于执行上述信号传输方法的本发明实施例的控制器进行说明，其 基本逻辑结构参考图 4, 本发明实施例中控制器一个实施例， 第一信号和第二 信号同时工作并共用一个天线， 该第一信号和该第二信号为共频带，射频前端 包括该天线， 该天线用于收发该第一信号和该第二信号的混合信号， 该控制器 包括：
确定单元 401、 判断单元 402、 第一执行单元 403、 和第二执行单元 404; 确定单元 401 , 用于确定该第一信号的优先级高于该第二信号的优先级； 判断单元 402, 用于在该第一信号和该第二信号同时工作时， 判断优先级 高的该第一信号的信号状态是否满足业务需求； 第一执行单元 403 , 用于在不满足该业务需求时， 将该天线接收到的该第 一信号和该第二信号的混合信号通过单刀双掷开关引导至第一信号的处理后 端；
第二执行单元 404, 用于在满足该业务需求时， 将该天线接收到的该第一 信号和该第二信号的混合信号通过该单刀双掷开关引导至功分器，并通过该功 分器将该第一信号和该第二信号的混合信号分别传递至该第一信号的处理后 端和第二信号的处理后端。
本实施例中， 控制器通过判断单元 402判断优先级高的第一信号的信号状 态是否满足业务需求来控制单刀双掷开关： 若不满足该业务需求， 第一执行单 元 403将该天线接收到的该第一信号和该第二信号的混合信号通过单刀双掷开 关引导至第一信号的处理后端； 若满足该业务需求， 则第二执行单元 404将该 天线接收到的该第一信号和该第二信号的混合信号通过该单刀双掷开关引导 至功分器，并通过该功分器将该第一信号和该第二信号的混合信号分别传递至 该第一信号的处理后端和第二信号的处理后端，这样能够实现两个共频带的信 号同时工作时， 共享一个天线， 并且能够保证优先级高的信号的业务需求， 提 供用户的体验。
下面以具体实施例对本发明实施例的控制器中包括的各个模块及单元间 的交互对服务器中的数据交互方式进行说明， 请参阅图 5 , 该控制器包括： 确定单元 501、 判断单元 502、 第一控制单元 503、 第二控制单元 504、 第一 执行单元 505和第二执行单元 506;
判断单元 502包括： 第一判断子单元 5021、 第一确定子单元 5022及第二确 定子单元 5023。
确定单元 501确定该第一信号的优先级高于该第二信号的优先级， 然后告 知第一判断子单元 5021第一信号的优先级高， 在实际应用中， 确定单元 501可 以根据该控制器所在的终端的业务导向来确定两个信号之间的优先级， 例如， CMCC的 SGLTE方案中 GSM信号和 LTE信号共频带，如果控制器所在的终端为 手机， 由于手机的业务导向为语音通话， 则确定单元 501可以确定 GSM信号的 优先级高于 LTE信号的优先级； 如果控制器所在的终端为平板电脑， 由于平板 电脑的业务导向为数据传输， 则确定单元 501可以确定 LTE信号的优先级高于 GSM信号的优先级， 在实际应用中， 确定单元 501还可以根据用户使用的频率 确定两个信号的优先级，例如， SGLTE方案中 GSM信号和 TDSCDMA信号共频 带， 如果用户使用 GSM频率高， 则确定单元 501确定 GSM信号的优先级高于 TDSCDMA信号的优先级， 此处如何确定两个信号的优先级不做限定。
第一判断子单元 5021判断该第一信号是否处于接收时隙， 且该第一信号 的接收信号强度是否小于第一门限值和 /或该第一信号的发送信号强度是否大 于第二门限值， 若该第一信号的接收信号强度小于该第一门限值和 /或该第一 信号的发送信号强度大于该第二门限值，且该第一信号处于接收时隙， 则告知 第一确定子单元 5022; 若该第一信号的接收信号强度大于或者等于该第一门 限值和 /或该第一信号的发送信号强度小于或者等于该第二门限值， 或者该第 一信号没有处于接收时隙， 则告知第二确定子单元 5023。
若该第一信号的接收信号强度小于该第一门限值和 /或该第一信号的发送 信号强度大于该第二门限值，且该第一信号处于接收时隙， 则第一确定子单元 5022 确定优先级高的该第一信号的信号状态不满足该业务需求， 然后告知第 一控制单元 503优先级高的该第一信号的信号状态不满足该业务需求。
若该第一信号的接收信号强度大于或者等于该第一门限值和 /或该第一信 号的发送信号强度小于或者等于该第二门限值，或者该第一信号没有处于接收 时隙， 则第二确定子单元 5023确定优先级高的该第一信号的信号状态满足该 业务需求，然后告知第二控制单元 504优先级高的该第一信号的信号状态满足 该业务需求。
需要说明的是， 当第一信号没有处于接收时隙时， 其实是没有接收第一信 号， 本实施例中是视为优先级高的该第一信号的信号状态满足该业务需求。
第一控制单元 503 通过逻辑控制接口输出的第一电压控制该单刀双掷开 关的第一端导通；

在实际应用中， 在单刀双掷开关上设置一个逻辑控制接口，控制器可以通 过逻辑控制接口输出两种电压， 一种是高电压， 一种是低电压， 若第一电压为 高电压时， 则第二电压为低电压； 若第一电压为低电压时， 则第二电压为高电 压，控制器可以通过逻辑控制接口输出的电压的高低来控制单刀双掷开关导通 端点。
第一执行单元 505 将该天线接收到的该第一信号和该第二信号的混合信 号通过单刀双掷开关引导至第一信号的处理后端，在实际应用中，通过单刀双 掷开关将天线收到的该第一信号和该第二信号的混合信号引导至第一信号的 处理后端， 此时天线接收到的混合信号只能供给第一信号的处理后端， 这样第 一信号的信号状态就能够满足业务需求。
第二执行单元 506 将该天线接收到的该第一信号和该第二信号的混合信 号通过该单刀双掷开关引导至功分器，并通过该功分器将该第一信号和该第二 信号的混合信号分别传递至该第一信号的处理后端和第二信号的处理后端，在 实际应用中， 功分器是功率分配器，是一种将一路输入信号能量分成两路或多 路输出相等或不相等能量的器件， 也可反过来将多路信号能量合成一路输出， 由于本发明实施例为两个信号， 所以使用的是一分二功分器， 这样就可以将混 合信号同时分享给第一信号的处理后端和第二信号的处理后端。
本实施例中，控制器通过第一判断子单元 5021判断该第一信号是否处于接 收时隙， 且该第一信号的接收信号强度是否小于第一门限值和 /或该第一信号 的发送信号强度是否大于第二门限值，第一确定子单元 5022或第二确定子单元 5023和第一控制单元 503或第二控制单元 504通过第一判断子单元 5021的判断 结果控制单刀双掷开关： 若不满足该业务需求， 第一执行单元 505将该天线接 收到的该第一信号和该第二信号的混合信号通过单刀双掷开关引导至第一信 号的处理后端； 若满足该业务需求， 则第二执行单元 506将该天线接收到的该 第一信号和该第二信号的混合信号通过该单刀双掷开关引导至功分器，并通过 该功分器分别将该第一信号和该第二信号的混合信号分别传递至该第一信号 的处理后端和第二信号的处理后端，这样能够实现两个共频带的信号同时工作 时， 共享一个天线， 并且能够保证优先级高的信号的业务需求， 提供用户的体 验。
下面以具体实施例对本发明实施例的控制器中包括的各个模块及单元间 的交互对服务器中的数据交互方式进行说明， 请参阅图 6, 该控制器包括： 确定单元 601、 判断单元 602、 第一控制单元 603、 第二控制单元 604、 第一 执行单元 605和第二执行单元 606;
判断单元 602包括： 第二判断子单元 6021、 第三确定子单元 6022及第四确 定子单元 6023。
确定单元 601确定该第一信号的优先级高于该第二信号的优先级， 然后告 知第二判断子单元 6021第一信号的优先级高， 在实际应用中， 确定单元 601可 以根据该控制器所在的终端的业务导向来确定两个信号之间的优先级， 例如， CMCC的 SGLTE方案中 GSM信号和 LTE信号共频带，如果控制器所在的终端为 手机， 由于手机的业务导向为语音通话， 确定单元 601可以确定 GSM信号的优 先级高于 LTE信号的优先级； 如果控制器所在的终端为平板电脑， 由于平板电 脑的业务导向为数据传输， 确定单元 601可以确定 LTE信号的优先级高于 GSM 信号的优先级， 在实际应用中， 确定单元 601还可以根据用户使用的频率确定 两个信号的优先级，例如，双卡双待双通方案中 GSM信号和 WCDMA信号共频 带， 如果用户使用 GSM频率高， 则确定单元 601确定 GSM信号的优先级高于 WCDMA信号的优先级， 此处如何确定两个信号的优先级不做限定。
第二判断子单元 6021判断该第一信号的接收信号强度是否小于第一门限 值和 /或该第一信号的发送信号强度是否大于第二门限值， 若该第一信号的接 收信号强度小于该第一门限值和 /或该第一信号的发送信号强度大于该第二门 限值， 则告知第三确定子单元 6022; 若该第一信号的接收信号强度大于或者等 于第一门限值和 /或该第一信号的发送信号强度小于或者等于第二门限值， 则 告知第四确定子单元 6023。
若该第一信号的接收信号强度小于第一门限值和 /或该第一信号的发送信 号强度大于第二门限值， 第三确定子单元 6022确定优先级高的该第一信号的 信号状态不满足该业务需求，然后告知第一控制单元 603优先级高的该第一信 号的信号状态不满足该业务需求。
若该第一信号的接收信号强度大于或者等于第一门限值和 /或该第一信号 的发送信号强度小于或者等于第二门限值， 第四确定子单元 6023确定优先级 高的该第一信号的信号状态满足该业务需求，然后告知第二控制单元 604优先 级高的该第一信号的信号状态满足该业务需求。
第一控制单元 603、 第二控制单元 604、 第一执行单元 605和第二执行单 元 606执行的操作与上述实施例中第一控制单元 503、 第二控制单元 504、 第 一执行单元 505和第二执行单元 506执行的操作相同， 此处不做赘述。
需要说明的是， 上述实施例由于需要判断接收时隙所以只适用于 TD制式 下共频带的两种信号，本实施例中由于只判断了信号强度所以适用于所以的共 频带的两种信号。
本实施例中，控制器通过第二判断子单元 6021判断该第一信号是否处于接 收时隙， 且该第一信号的接收信号强度是否小于第一门限值和 /或该第一信号 的发送信号强度是否大于第二门限值，第三确定子单元 6022或第四确定子单元 6023和第一控制单元 603或第二控制单元 604通过第二判断子单元 6021的判断 结果控制单刀双掷开关： 若不满足该业务需求， 第一执行单元 605将该天线接 收到的该第一信号和该第二信号的混合信号通过单刀双掷开关引导至第一信 号的处理后端； 若满足该业务需求， 则第二执行单元 606将该天线接收到的该 第一信号和该第二信号的混合信号通过该单刀双掷开关引导至功分器，并通过 该功分器分别将该第一信号和该第二信号的混合信号分别传递至该第一信号 的处理后端和第二信号的处理后端，这样能够实现两个共频带的信号同时工作 时， 共享一个天线， 并且能够保证优先级高的信号的业务需求， 提供用户的体 验。

若该第一信号的接收信号强度大于或者等于该第一门限值和 /或该第一信 号的发送信号强度小于或者等于该第二门限值，或者该第一信号没有处于接收 时隙， 则控制器 200确定优先级高的该第一信号的信号状态满足该业务需求， 然后控制器 200通过逻辑控制接口向单刀双掷开关 S1输出第二电压， 以控制 单刀双掷开关 S1的第二端导通， 天线 100接收到的第一信号和第二信号的混 合信号经由单刀双掷开关的第二端到功分器 300的输入端，功分器 300再将接 收到的该第一信号和该第二信号的混合信号通过功分器 300 的第一输出端和 第二输出端分别传递至该第一信号的处理后端和该第二信号的处理后端，然后 第一信号的处理后端 400和第二信号的处理后端 500分别对各自接收到的第一 信号和第二信号的混合信号进行处理， 在实际应用中， 第一信号的处理后端 400可以过滤掉第二信号而只保留第一信号， 第二信号的处理后端 500可以过 滤掉第一信号而只保留第二信号。

当该第一信号的接收信号强度大于或者等于第一门限值和 /或该第一信号 的发送信号强度小于或者等于第二门限值时，控制器 200确定优先级高的该第 一信号的信号状态满足该业务需求，然后控制器 200通过逻辑控制接口向单刀 双掷开关 S1输出第二电压， 以控制单刀双掷开关 S1的第二端导通， 天线 100 接收到的第一信号和第二信号的混合信号经由单刀双掷开关的第二端到功分 器 300的输入端，功分器 300再将接收到的该第一信号和该第二信号的混合信 号通过功分器 300 的第一输出端和第二输出端分别传递至第一信号的处理后 端 400和第二信号的处理后端 500, 然后第一信号的处理后端 400和第二信号 的处理后端 500 分别对各自接收到的第一信号和第二信号的混合信号进行处 理，在实际应用中， 第一信号的处理后端 400可以过滤掉第二信号而只保留第 一信号， 第二信号的处理后端 500可以过滤掉第一信号而只保留第二信号。
