具体实施方式
下面详细描述本申请的实施方式，所述实施方式的示例在附图中示出，其中，相同或类似的标号自始至终表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施方式是示例性的，仅用于解释本申请的实施方式，而不能理解为对本申请的实施方式的限制。
请参阅图1及图2，本申请实施方式提供一种应用于通信系统100的重定向方法。通信系统100包括第一网络设备10、第二网络设备20及终端设备30。重定向方法包括：
011：第二网络设备20发送第一频点信息至第一网络设备10，第一频点信息包括布网方案为支持双连接的第一频点；
012：第一网络设备10接收第一频点信息；
013：第一网络设备10根据第一频点信息生成重定向信息；
014：第一网络设备10将重定向信息发送至终端设备30；及
015：终端设备30接收重定向信息。
请继续参阅图1和图2，本申请实施方式还提供一种通信系统100。通信系统100包括第一网络设备10、第二网络设备20及终端设备30。第二网络设备20包括通信模块21。步骤011可以由通信模块21实现。第一网络设备10包括通信单元11及处理电路12。步骤012及步骤014可以由通信单元11实现，步骤013可以由处理电路12实现。终端设备30包括通信元件31。步骤015可以由通信元件31实现。
也即是说，通信模块21用于发送第一频点信息至第一网络设备10，第一频点信息包括布网方案为支持双连接的第一频点。通信单元11用于接收第一频点信息。处理电路12用于根据第一频点信息生成重定向信息。通信单元11还用于将重定向信息发送至终端设备30。通信元件31用于接收重定向信息。
其中，第一网络设备10可以为用于实施某一移动通信技术的无线通信设施，例如，可以为用于实施第二代移动通信技术(2G)的无线通信设施或者用于实施第三代移动通信技术(3G)的无线通信设施等。第二网络设备20可以为用于实施另一移动通信技术的无线通信设施，例如可以为用于实施第四代移动通信技术(4G)的无线通信设施等。终端设备30也可称为用户设备(User Equipment，UE)，或者可称之为移动台(Mobile Station，简称为MS)、移动终端设备30(Mobile Terminal)等。例如，终端设备30可以是移动电话(或称为“蜂窝”电话)、具有移动网络接入功能的计算机等；例如，终端设备30还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语音和/或数据；例如，终端设备30还可以是可实现D2D(Device to Device，设备到设备)的终端设备30或者可实现M2M(Machine to Machine，机器到机器)的终端设备30等，在此不作限制。
具体地，当第一网络设备10需要向终端设备30发起重定向请求时，第二网络设备20的通信模块21会将第二网络设备20的第一频点信息发送至第一网络设备10。其中，第一频点信息包括布网方案为支持双连接的第一频点。第一频点信息中的第一频点的数量可以为一个或多个，在此不作限制。其中，双连接可以指代4G和5G之间的双连接，第二网络设备20中，使用布网方案为支持双连接的第一频点的小区(4G)具有为接入到该小区的终端设备30配置5G的频点，以使得终端设备30可以使用5G无线通信网络的能力。使用布网方案为不支持双连接的第一频点的小区(4G)则不具有为接入该小区的终端设备30配置5G频点的能力。4G无线通信网络中的哪些第一频点的布网方案为支持双连接，哪些第一频点的布网方案为不支持双连接，是由网络运营商决定的。例如，某一网络运营商提供了10000个第一频点，在位置A的4G基站上，布置了100、101及 102三个第一频点，其中只有100这个第一频点支持双连接。当网络布置好之后，该第二网络设备20的4G基站就会知道本4G基站的各个第一频点及各个第一频点的布网方案。第二网络设备20接收到信息请求后，可以将支持双连接的第一频点100发送给第一网络设备10。需要说明的是，在其他实施例中，双连接除了指代核心网为4G核心网、锚点为4G基站的4G和5G之间的双连接(即EN-DC)以外，还可以指代核心网为5G核心网、锚点为5G基站的4G和5G之间的双连接(即NE-DC)，还可以指代核心网为5G核心网、锚点为升级之后的4G基站的4G和5G之间的双连接(即NGEN-DC)等，在此不作限制。甚至地，双连接还可以指代其他任意两个无线通信网络之间的双连接，例如4G与6G之间的双连接、5G与6G之间的双连接等，在此也不作限制。
第一网络设备10的通信单元11接收到第二网络设备20发送的第一频点信息后，第一网络设备10中的处理电路12可以根据布网方案为支持双连接的第一频点生成重定向信息。通信单元11将该重定向信息发送至终端设备30，终端设备30接收到重定向信息之后可以根据该重定向信息进行重定向。示例地，终端设备30接收到第一网络设备10发送的重定向消息后，释放与第一网络设备10之间的连接，并根据重定向消息中携带的第一频点，向对应该第一频点的第二网络设备20发送连接请求，以重定向到第二网络设备20。
可以理解，在第一网络设备10对应的通信网络的存在信号差、网络拥塞或需要变更网络策略的时候，第一网络设备10会向终端设备30提供相关的频点信息，以使得终端设备30可以进行重定向。但终端设备30在进行重定向的时候不知道第一网络设备10发送给它的频点中，哪些频点的布网方案支持双连接，以至于终端设备30很可能会重定向到布网不支持双连接的频点上，导致终端设备30驻网失败。
本申请实施方式的重定向方法和通信系统100中，第一网络设备10将第二网络设备20发送的根据布网方案为支持双连接的第一频点生成的重定向信息发送至终端设备30，使得终端设备30可以根据该重定向信息优先重定向到目标的频点，从而可以极大地提高终端设备30在一个无线通信网络上通过双连接成功接入另一个无线通信网络的概率。
请参阅图2及图3，在某些实施方式中，重定向方法还包括：
016：第一网络设备10发送信息请求至第二网络设备20；
017：第二网络设备20接收信息请求。
步骤011第二网络设备20发送第一频点信息至第一网络设备10包括：
0111：第二网络设备20根据信息请求发送第一频点信息至第一网络设备10。
请参阅图2及图3，在某些实施方式中，步骤016可以由通信单元11实现，步骤017及步骤0111可以由通信模块21实现。
也即是说，通信单元11还用于发送信息请求至第二网络设备20。通信模块21还用于接收信息请求，并根据信息请求发送第一频点信息至第一网络设备10。
具体地，当第一网络设备10需要向终端设备30发起重定向请求时，第一网络设备10的通信单元11首先会向第二网络设备20发送信息请求，以请求第二网络设备20向其发送第一频点信息。第二网络设备20接收到信息请求后再根据该信息请求将第一频点信息发送至第一网络设备10。在第二网络设备20接收到信息请求后，第二网络设备20才向第一网络设备10发送第一频点信息，一方面可以避免在第一网络设 备10不需要第一频点信息时，第二网络设备20向其发送第一频点信息，从而增大第一网络设备10与第二网络设备20之间的传输开销的问题，另一方面第二网络设备20可以及时地发送第一频点信息给第一网络设备10，保证终端设备30能够及时地进行重定向。
图4是一个实施例的第一网络设备10与第二网络设备20之间的信息交互示意图。如图2和图4所示，当第一网络设备10为用于实施第二代移动通信技术(2G)的无线通信设施时，第一网络设备10包括2G基站(GERAN BSS)和GPRS服务支持节点(Serving GPRS Support Node，SGSN)，此时，通信单元11可以同时包括位于2G基站内的通信单元和位于GPRS服务支持节点内的通信单元，处理电路12可以同时包括位于2G基站内的处理电路和位于GPRS服务支持节点内的处理电路；当第一网络设备10为用于实施第三代移动通信技术(3G)的无线通信设施时，第一网络设备10包括3G基站(UTRAN RNC)和GPRS服务支持节点(Serving GPRS Support Node)，通信单元11可以同时包括位于3G基站内的通信单元和位于GPRS服务支持节点内的通信单元，处理电路12可以同时包括位于3G基站内的处理电路和位于GPRS服务支持节点内的处理电路。第二网络设备20例如可为用于实施第四代移动通信技术(4G)的无线通信设施，第二网络设备20包括移动管理实体(Mobility Management Entity，MME)及4G基站(E-UTRAN enodeB，也称为LTE基站)，此时，通信模块21可以同时包括位于移动管理实体内的通信模块及位于4G基站内的通信模块。
下面以第一网络设备10为用于实施第二代移动通信技术(2G)的无线通信设施，第二网络设备20为用于实施第四代移动通信技术(4G)为例，对第一网络设备10与第二网络设备20之间的信息交互进行说明。
如图2和图4所示，当第一网络设备10需要向终端设备30发起重定向请求时，2G基站首先会通过直接信息传递(DIRECT INFORMATION TRANSFER)的格式向GPRS服务支持节点发送信息请求信令(RAN INFORMATION REQUEST)。GPRS服务支持节点收到信息请求信令后，再通过RAN信息中继(RAN INFORMATION RELAY)的格式将该信息请求信令转发至移动管理实体。MME收到信息请求信令后，再通过MME直接信息传递(MME DIRECT INFORMATION TRANSFER)的格式将该信息请求信令发送至4G基站。4G基站接收到该信息请求信令后，根据该信息请求信令通过4G基站直接信息传递(eNB DIRECT INFORMATION TRANSFER)的格式将包含第一频点信息的信令(RAN INFORMATION)发送至MME。MME收到该包含第一频点信息的信令后，再通过RAN信息中继(RAN INFORMATION RELAY)的格式将包含第一频点信息的信令转发至GPRS服务支持节点。GPRS服务支持节点收到该包含第一频点信息的信令后再通过直接信息传递(DIRECT INFORMATION TRANSFER)的格式将该包含第一频点信息的信令发送至2G基站。
可以理解，2G基站或3G基站发送信息请求至4G基站后，4G基站发送给2G基站或3G基站的信令中通常不包含4G无线通信技术使用的第一频点，也不包含与第一频点对应的布网方案。本申请实施方式的重定向方法中，4G基站在接收到2G基站或3G基站发送的信息请求后，会将第一频点及与第一频点对应的布网方案均添加到信令中，从而使得2G基站或3G基站可以了解到4G无线通信网络的第一频点及对应 的布网情况。
请参阅图2及图5，在某些实施方式中，第一频点信息还包括布网方案为不支持双连接的第一频点；第一网络设备10根据第一频点信息生成重定向信息的步骤013，包括：
018：第一网络设备10从第一频点信息中选出布网方案为支持双连接的至少一个第一频点。
请继续参阅图2及图5，在某些实施方式中，步骤018可以由处理电路12实现。
也即是说，处理电路12还用于从第一频点信息中选出布网方案为支持双连接的至少一个第一频点。
具体地，在重定向的过程中，第二网络设备20可以将自身的第一频点信息发送至第一网络设备10，第一频点信息可以同时包括布网方案为支持双连接的第一频点及布网方案为不支持双连接的第二频点。第一网络设备10可以从第一频点信息中选取出至少一个第一频点以用于生成重定向信息。在一个例子中，第二网络设备20可以为每个第一频点增加对应的属性字段，用于向第一网络设备10指示该第一频点是否是支持双连接的，便于后续处理电路12从第一频点信息中选出布网方案为支持双连接的至少一个第一频点。例如，可以对每个第一频点增加属性字段endc_flag来指示该第一频点是否是支持双连接的，可以设置endc_flag＝1来指示该第一频点支持双连接，endc_flag＝0来指示该第一频点不支持双连接。那么，在第一网络设备10接收到第一频点信息后，第一网络设备10即可在第一频点信息中找出endc_flag＝1的第一频点以作为目标的频点。当然，在其他例子中，也可以设置endc_flag＝1来指示该第一频点不支持双连接，endc_flag＝0指示该第一频点支持双连接，具体的数值与布网方案对应关系，可由开发人员确定，或者由标准制定人员引入3GPP标准，后续再由开发人员按照该3GPP标准来实现等，在此不作限制。
请参阅图2及图6，在某些实施方式中，重定向方法还包括：
019：终端设备30发送第二频点信息至第一网络设备10，第二频点信息包括终端设备30能够使用的第二频点；
020：第一网络设备10接收第二频点信息；
步骤018第一网络设备10从第一频点信息中选出布网方案为支持双连接的至少一个第一频点包括：
0181：第一网络设备10从第一频点信息及第二频点信息中选出至少一个第一频点，至少一个第一频点的布网方案为支持双连接，且至少一个第一频点与第二频点为相同频点；
步骤015终端设备30接收重定向信息包括：
0151：终端设备30接收第一网络设备10发送的根据布网方案为支持双连接且与第二频点为相同频点的第一频点生成的重定向信息；
重定向方法还包括：
021：终端设备30根据布网方案为支持双连接且与第二频点为相同频点的第一频点进行重定向。
请继续参阅图2及图6，在某些实施方式中，步骤019、步骤0151及步骤021均可以由通信元件31实现，步骤020可以由通信单元11实现，步骤0181及步骤0131可以由处理电路12实现。
也即是说，通信元件31还用于发送第二频点信息至第一网络设备10，第二频点信息 包括终端设备30能够使用的第二频点。通信单元11还用于接收第二频点信息。处理电路12还用于从第一频点信息及第二频点信息中选出至少一个第一频点，至少一个第一频点的布网方案为支持双连接，且至少一个第一频点与第二频点为相同频点。通信元件31还用于接收第一网络设备10发送的根据布网方案为支持双连接且与第二频点为相同频点的第一频点生成的重定向信息，并根据布网方案为支持双连接且与第二频点为相同频点的第一频点进行重定向。
可以理解，第二网络设备20所发送的第一频点信息中，并不是所有的第一频点都能够被终端设备30使用，因此第一网络设备10需要接收终端设备30发送的终端设备30能够使用的第二频点信息，处理电路12再从第一频点信息及第二频点信息中选出布网方案为支持双连接且与第二频点为相同频点的至少一个第一频点，并根据布网方案为支持双连接且与第二频点为相同频点的至少一个第一频点生成重定向信息。终端设备30接收第一网络设备10发送的根据布网方案为支持双连接且与第二频点为相同频点的第一频点生成的重定向信息，并根据该重定向信息进行重定向。其中，第二频点信息中的第二频点的数量可以是一个或者多个，在此不作限制。例如，第二网络设备20发送的第一频点信息包括100、101及102三个第一频点，其中，第一频点100和第一频点101均支持双连接。而终端设备30发送的第二频点信息包括101及103两个第二频点，则处理电路12从100、101及102这三个第一频点中确定第一频点101为既支持双连接又可以被终端设备30使用的目标频点。处理电路12获得该目标频点后，处理电路12会根据该目标频点生成重定向信息，并由通信单元11发送至终端设备30。终端设备30接收到该重定向信息之后会根据目标频点进行重定向，当终端设备30重定向到了该目标频点后，第二网络设备20就会根据终端设备30的网络需求来决定是否给终端设备30配置到双连接状态。在一个例子中，当终端设备30处于播放电影、玩游戏等状态下时，终端设备30需要更快更好的网速，此时第二网络设备20就可以给终端设备30配置到双连接状态，此时终端设备30的网络连接从原本的单连接通道变成了双连接通道，网速变快；在另一个例子中，当终端设备30处于语音通话、网页浏览等状态下时，终端设备30所需要的数据量较小，此时第二网络设备20可以不给终端设备30配置到双连接状态。当然，在其他例子中，配置策略也可以为只要终端设备30重定向到了该终端设备30能够使用的目标频点对应的网络中，第二网络设备20就给终端设备30配置双连接。具体配置策略可由网络运营商根据实际应用场景确定，在此不作限制。
请参阅图2及图7，在某些实施方式中，重定向方法在终端设备30接收重定向信息的步骤015后还包括：
022：终端设备30根据重定向信息及第二频点确定布网方案为支持双连接且与第二频点为相同频点的第一频点为目标频点，第二频点为终端设备30能够使用的频点；及
023：终端设备30根据目标频点进行重定向。
请继续参阅图2及图6，在某些实施方式中，终端设备30还包括处理芯片32。步骤022可以由处理芯片32实现，步骤023可以由通信元件31实现。也即是说，处理芯片32用于根据重定向信息及第二频点确定布网方案为支持双连接且与第二频点为相同频点的第一频点为目标频点，第二频点为终端设备30能够使用的频点。通信元件31还用于终端设备30根据目标频点进行重定向。
可以理解，第二网络设备20所发送的第一频点信息中，并不是所有的第一频点都能够被终端设备30使用。因此，终端设备30在接收到重定向信息后，可以根据重定向信息以及终端设备30能够使用的第二频点确定布网方案为支持双连接且与第二频点为相同频点的第一频点为目标频点。例如，第二网络设备20发送的第一频点信息包括100、101及102三个第一频点，其中，第一频点100和第一频点101均支持双连接。第一网络设备10的处理电路12根据支持双连接的第一频点100和101生成重定向信息，通信单元11将重定向信息发送给终端设备30。终端设备30的通信元件31接收到重定向信息后将该重定向信息传送给处理芯片32。处理芯片32从重定向信息中获取100和101这两个第一频点，并结合终端设备30自身能够使用的第二频点101和103，确定出第一频点101为既支持双连接又可以被终端设备30使用的目标频点。终端设备30可对该目标频点进行优先重定向，从而可以极大地提高终端设备30在一个无线通信网络上通过双连接成功接入另一个无线通信网络的概率。
综上，本申请实施方式的重定向方法、第一网络设备10、第二网络设备20及通信系统100中，第一网络设备10将第二网络设备20发送的根据布网方案为支持双连接的第一频点生成的重定向信息发送至终端设备30，使得终端设备30可以根据该重定向信息优先重定向到目标的频点，从而可以极大地提高终端设备30在一个无线通信网络上通过双连接成功接入另一个无线通信网络的概率。
