在5G网络的布网初期，语音方案多采用回落方式实现，也就是EPS(Evolved Packet System，演进的分组系统)fallback(回落)。尤其是异网漫游场景的EPS回落需要优先回落到Home(归属地)网络的4G网络上。由于成本考虑和不同运营商之间的信息保密要求，运营商之间有些信息共享并不能充分保证，因此，终端设备再进行EPS回落的时候，会出现无法尽快的接入4G网络的问题，这样就会对整个通信系统的服务质量产生影响。

需要说明的是，本发明实施例所记载的技术方案之间，在不冲突的情况下，可以任意组合。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统或5G系统等。
示例性的，本申请实施例应用的通信系统100可以如图1所示。该通信系统100可以包括网络设备110，网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。可选地，该网络设备110可以是GSM系统或CDMA系统中的网络设备(Base Transceiver Station，BTS)，也可以是WCDMA系统中的网络设备(NodeB，NB)，还可以是LTE系统中的演进型网络设备(Evolutional Node B，eNB或eNodeB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
该通信系统100还包括位于网络设备110覆盖范围内的至少一个终端设备120。作为在此使用的“终端设备”包括但不限于经由有线线路连接，如经由公共交换电话网络(Public Switched Telephone Networks，PSTN)、数字用户线路(Digital Subscriber Line，DSL)、数字电缆、直接电缆连接；和/或另一数据连接/网络；和/或经由无线接口，如，针对蜂窝网络、无线局域网(Wireless Local Area Network，WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器；和/或另一终端设备的被设置成接收/发送通信信号的装置；和/或物联网(Internet of Things，IoT)设备。被设置成通过无线接口通信的终端设备可以被称为“无线通信终端”、“无线终端”或“移动终端”。

为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
由于相关技术中，终端设备处于异网漫游的5G小区中的时候，出现语音回落的情况下，终端设备如果再次重新搜索4G小区进而接入4G小区，那么就会产生接入时延较长的问题，无法保证通信质量以及通信效率。
因此，本申请提供的异网漫游的方案中，引入了频点映射关系，在频点映射关系中设置有第一类通信网络中的第一类小区，以及与所述第一类小区具备邻区覆盖关系的第二类通信网络中的第二类小区；其中，所述第一类通信网络为5G网络，第二类通信网络为4G网络。通过所述频点映射关系，使得终端设备能够快速的确定当前使用的服务小区也就是5G小区相邻或者存在覆盖关系的4G小区，然后直接切换到4G小区即可。如此，减少了切换时延，提升了在发生语音回落的场景下小区切换的效率，保证了通信系统的服务质量以及处理效率。
为了实现上述目标，本实施例提供了以下两种实施方式：
一种实施例中，提供了一种信息处理方法，如图2所示，包括：
步骤21：终端设备处于第一类通信网络中的第一小区且所述终端设备发生语音回落时，根据频点映射关系从第二类通信网络中的至少一个第二类小区中确定所要接入的第二小区；其中，所述第一类通信网络与所述第二类通信网络的提供服务的网络节点不同，所述第二类通信网络为终端设备的归属地网络；所述频点映射关系，包括：所述第一类通信网络中的第一类小区，以及与所述第一类小区具备邻区覆盖关系的第二类通信网络的至少一个第二类小区；所述第一类小区中包括所述第一小区；
步骤22：所述终端设备由所述第一小区切换至所述第二小区进行数据传输。
其中，所述第一类通信网络的覆盖范围小于所述第二类通信网络的覆盖范围，具体来说，所述第一类通信网络为5G网络，第二类通信网络为4G网络。
另外，第一类通信网络与第二类通信网络的提供服务的网络节点不同，具体的，可以为第一类通信网络的运营商与第二类通信网络的运营商不同。
本实施例提供的方案的一种适用场景为，终端设备处于异网漫游情况下，处于与归属地网络不同的运营商提供的第一类通信网络的第一小区(可以称为异网漫游5G小区)中，在当前的5G布网初级阶段，由于针对语音处理通常采用回落方式实现，比如EPS回落，那么就需要将终端设备的通信回落至归属地网络提供的4G小区也就是第二小区中。
具体的实现方式为：终端设备通过频点映射关系来确定所要接入的第二小区。
其中，所述频点映射关系可以为预设的，或者可以为网络设备发给终端设备的。当所述频点映射关系为预设的时候，可以由终端设备采集得到。
具体的采集方式可以为：所述终端设备建立异网漫游数据库，将至少一个第一类通信网络的第一类小区，以及与所述至少一个第一类小区中每一个第一类小区具备邻区覆 盖关系的第二类通信网络的至少一个第二类小区作为所述频点映射关系保存在所述异网漫游数据库中。
一种示例中，由于终端设备的位置是可以移动的，那么也就意味着终端设备可能在不同的时间段处于不同的小区；终端设备将其历史所处的全部小区的标识及其频点保存至异网漫游数据库中。从全部小区中先确定第一类通信网络的至少一个第一类小区；分别确定每一个第一类小区具备邻区覆盖关系的至少一个第二类通信网络的第二类小区；将第一类小区与其具备邻区覆盖关系的第二类通信网络的一个或多个第二类小区相关联保存至频点映射关系中；然后将频点映射关系保存在异网漫游数据库中。
由于第一类小区为终端设备在使用过程中得到的，那么可以将第一类小区认为是终端设备常用的异网漫游小区。也就是说，存储常用的5G异网漫游的数据库，并存储异网漫游的5G小区和归属地4G小区的邻区覆盖的映射关系。需要指出的是，这里可以对终端设备维护的异网漫游数据库中所包含的频点映射关系中的第一类小区的数量进行限定，比如，可以设置该数量不能大于预设数值(比如100个)。
举例来说，终端设备通过自学习机制涵盖了移动场景，如果存在多个移动场景，采用最常用的5G漫游作为常用小区(或者，可以称为常用的第一类通信网络的第一类小区)，常用小区的数量大小可以在工程实施时确定，比如维护100个5G异网漫游小区。在频点映射关系中，主要维护这些常用小区，也就是常用的第一类通信网络的第一类小区及其对应的第二类通信网络的至少一个第二类小区。
前述第一类小区及其对应的第二类小区为具备邻区覆盖关系的，所谓的邻区覆盖关系，可以认为是第一类小区处于第二类小区的覆盖范围内，或者，第一类小区处于第二类小区的覆盖范围边缘。
进一步地，当基于所述频点映射关系，确定与所述第一小区具备邻区覆盖关系的第二类小区为一个时，将所述第二类小区作为所述第二小区；
当基于所述频点映射关系，确定与所述第一小区具备邻区覆盖关系的第二类小区为至少两个时，从所述至少两个第二类小区中选取一个作为所述第二小区。
其中，所述从所述至少两个第二类小区中选取一个作为所述第二小区，可以为，从所述至少两个第二类小区中选取一个作为第二小区，可以根据信号质量进行选取，比如，可以选择信号质量最强的一个作为第二小区。所述参考信号的强度可以通过RSRP、SNR等一个或多个参数来表示，这里不再穷举。
这里，由于本实施例优选针对了第一类小区为5G小区，第二类小区为4G小区的场景，那么关于邻区覆盖关系，需要基于5G小区以及4G小区之间的覆盖特点进行说明：5G小区覆盖范围小于4G小区。通常的情况下，一个4G小区下可以涵盖一个或多个5G小区。比如，如果是边界交叉，则会出现一个5G小区对应两个或者多个4G小区的情况，可以采用信号最强的4G小区作为优先接入小区。
举例说明，参见图3：4G小区-1可以为终端设备的归属地4G小区；当终端设备处于异网漫游的5G小区-1中的时候，如果发生语音回落(EPS回落)那么可以根据频点映射关系，确定与5G小区-1具备邻区覆盖关系的第二小区为4G小区-1，因此终端设备可以切换至4G小区-1。
又或者，同样基于图3，当终端设备处于异网漫游的5G小区-2中的时候，如果发 生语音回落(EPS回落)那么可以根据频点映射关系，确定与5G小区-2具备邻区覆盖关系的第二小区为4G小区-1以及4G小区-2，因此终端设备可以从两个4G小区中选取一个信号质量最好的作为第二小区进行接入，假设4G小区-2信号质量最好，那么就将4G小区-2作为第二小区，终端设备由5G小区-2切换至4G小区-2。
进一步地，基于前述实施例的描述，当终端设备由第二小区切换至第一小区，通过第二小区进行语音通信处理，后续步骤不再进行赘述。
本实施例的一种具体示例，可以参见图4，具体的：当终端设备所在的异网漫游的5G小区(也就是第一小区)时，第一小区的网络设备(gNB基站)接收到终端设备对应的语音呼叫；向所述终端设备发送RRC释放指令，也就是终端设备此时发生语音回落，由于RRC释放指令中没有携带第二小区的频点，因此，终端设备可以采用自学习得到的频点映射关系，选取与第一小区具备相邻覆盖关系的第二小区(归属网4G小区)，并由第一小区切换至第二小区，通过第二小区完成语音通信处理。
一种实施例中，提供了一种信息处理方法，如图5所示，包括：
步骤31：当网络设备的覆盖范围中第一小区内的终端设备发生语音回落时，所述网络设备根据频点映射关系从与所述第一小区具备邻区覆盖关系的第二类小区中确定所要接入的第二小区；其中，所述第一小区为第一类通信网络中的第一类小区，所述第二类小区为第二类通信网络中的小区；所述第一类通信网络与所述第二类通信网络的提供服务的网络节点不同，所述第二类通信网络为终端设备的归属地网络；所述频点映射关系，包括：所述第一类通信网络中的第一类小区，以及与所述第一类小区具备邻区覆盖关系的第二类通信网络的至少一个第二类小区；
步骤32：所述网络设备向所述终端设备发送所述第二小区的相关信息；所述第二小区的相关信息用于所述终端设备能够由第一小区切换至所述第二小区。
相应的，一种信息处理方法，如图6所示，所述方法包括：
步骤41：终端设备处于第一小区、且发生语音回落时，接收网络设备发来的第二小区的相关信息；
步骤42：所述终端设备基于所述第二小区的相关信息确定所述第二小区、且由第一小区切换至所述第二小区；其中，所述第一小区为第一类通信系统中的小区，所述第二小区为第二类通信网络中的小区，所述第一类通信网络与所述第二类通信网络的提供服务的网络节点不同；所述第二类通信网络为终端设备的归属地网络；所述第二小区的相关信息由网络设备基于频点映射关系确定，所述频点映射关系包括：所述第一类通信网络中的第一类小区，以及与所述第一类小区具备邻区覆盖关系的第二类通信网络中的第二类小区；所述第一类小区中包含所述第一小区。
其中，第一类通信网络的覆盖范围小于第二类通信网络的覆盖范围。具体来说，所述第一类通信网络为5G网络，第二类通信网络为4G网络。
第一类通信网络与第二类通信网络的提供服务的网络节点不同，具体可以为第一类通信网络的运营商与第二类通信网络的运营商不同。
所述网络设备为第一类通信网络中的基站，优选的为5G网络中的gNB。
本实施例提供的方案，终端设备处于异网漫游情况下，处于与归属地网络不同的运营商提供的第一类通信网络的第一小区(可以称为异网漫游5G小区)中，在当前的5G 布网初级阶段，由于针对语音处理通常采用回落方式实现，比如EPS回落，那么就需要将终端设备的通信回落至归属地网络提供的4G小区也就是第二小区中。
具体的实现方式为：终端设备通过网络设备发来的指令完成切换的；其中，网络设备可与预先存储频点映射关系。
本实施例中，与前述实施例不同就在于频点映射关系由网络设备来建立，而不是通过终端设备。
具体的，增加一个测试终端(Test UE)，其作用是学习归属地的邻区关系，然后把邻区关系上报给漫游地的5G的基站，也就是所述网络设备。
其中，测试终端可以设置一定的移动范围，由于测试终端主要是向所在归属地4G网络下上报对应的邻区覆盖关系，因此可以将测试终端的移动范围设置在4G网络的小区范围内，在该范围内检测异网漫游5G小区，然后建立4G小区与5G小区之间的相邻覆盖关系，建立频点映射关系，将频点映射关系上报到5G小区的网络设备中(gNB)。
所述网络设备接收测试终端发来的包含有至少一个第一类通信网络的第一类小区，以及与所述至少一个第一类小区中每一个第一类小区具备邻区覆盖关系的第二类通信网络的至少一个第二类小区的所述频点映射关系，将所述频点映射关系保存在异网漫游数据库。
进一步地，网络设备获取到测试终端上报的内容的方式可以为通过应用层获取，也就是说，测试终端通过应用层向网络设备上报前述频点映射关系。
又或者，测试终端仅负责获取到第一类小区及与其具备邻区覆盖关系的第二类小区的关系，然后通过应用层上报至第一类小区所对应的网络设备，由所述网络设备将第一类小区以及第二类小区添加至频点映射关系中保存在异网漫游数据库中。
进一步地，当基于所述频点映射关系，所述网络设备确定与所述第一小区具备邻区覆盖关系的第二类小区为一个时，将所述第二类小区作为所述第二小区；
当基于所述频点映射关系，所述网络设备确定与所述第一小区具备邻区覆盖关系的第二类小区为至少两个时，从所述至少两个第二类小区中选取一个作为所述第二小区。
其中，所述从所述至少两个第二类小区中选取一个作为所述第二小区，可以为，从所述至少两个第二类小区中选取一个作为第二小区，可以根据信号质量进行选取，比如，可以选择信号质量最强的一个作为第二小区。所述参考信号的强度可以通过RSRP、SNR等一个或多个参数来表示，这里不再穷举。
这里，由于本实施例优选针对了第一类小区为5G小区，第二类小区为4G小区的场景，那么关于邻区覆盖关系，需要基于5G小区以及4G小区之间的覆盖特点进行说明：5G小区覆盖范围小于4G小区。通常的情况下，一个4G小区下可以涵盖一个或多个5G小区。比如，如果是边界交叉，则会出现一个5G小区对应两个或者多个4G小区的情况，可以采用信号最强的4G小区作为优先接入小区。
举例说明，参见图3：4G小区-1可以为终端设备的归属地4G小区；当终端设备处于异网漫游的5G小区-1中的时候，如果发生语音回落(EPS回落)那么可以根据频点映射关系，确定与5G小区-1具备邻区覆盖关系的第二小区为4G小区-1，网络设备可以通过RRC释放信令向终端设备指示第二小区的频点，因此终端设备根据RRC释放信令指示的第二小区的频点进行扫描，然后可以切换至4G小区-1。需要理解的是，RRC 释放信令中除了第二小区的频点之外，还可能包含其他内容，比如第二小区的标识(ID)等等，只是本实施例中不做穷举。
又或者，同样基于图3，当终端设备处于异网漫游的5G小区-2中的时候，如果发生语音回落(EPS回落)那么可以根据频点映射关系，确定与5G小区-2具备邻区覆盖关系的第二小区为4G小区-1以及4G小区-2，因此可以从两个4G小区中选取一个信号质量最好的作为第二小区，假设4G小区-2信号质量最好，那么就将4G小区-2作为第二小区，网络设备可以通过RRC释放信令向终端设备指示第二小区的频点，因此终端设备根据RRC释放信令指示的第二小区的频点进行扫描，然后可以切换至4G小区-2。需要理解的是，RRC释放信令中除了第二小区的频点之外，还可能包含其他内容，比如第二小区的标识(ID)等等，只是本实施例中不做穷举。
进一步地，基于前述实施例的描述，当终端设备由第二小区切换至第一小区，通过第二小区进行语音通信处理，后续步骤不再进行赘述。
本实施例的一种具体示例，可以参见图7，具体的：当终端设备所在的异网漫游的5G小区(也就是第一小区)时，第一小区的网络设备(gNB基站)接收到终端设备对应的语音呼叫；向所述终端设备发送RRC释放指令，也就是终端设备此时发生语音回落，由于RRC释放指令中携带第二小区的频点，因此，终端设备可以采用RRC释放信令的指示确定第二小区，然后所述终端设备由第一小区切换至第二小区，通过第二小区完成语音通信处理。
本实施例的一种架构示例，可以参见图8，gNB即为网络设备，也就是异网漫游5G小区的基站，NB可以为终端设备的归属地4G小区的基站；gNB将测试终端可以测试得到异网漫游5G小区具备邻区覆盖关系的归属地4G小区的映射关系，然后上报的频点映射关系保存在数据库(异网漫游数据库)中；终端设备可以通过gNB下发的RRC释放信令获取到对应的第二小区的相关信息，也就是4G小区的频点等相关信息，终端设备可以切换到第二小区的NB中进行后续的语音通信数据的传输交互等处理。
另外，还可能存在一种处理方式，就是在终端设备出现语音回落情况的时候，可以由网络设备直接将频点映射关系发送给终端设备，然后终端设备可以根据前述第一个实施例中提供的方案进行后续处理，这里不再赘述。也就是说，由网络设备进行频点映射关系的建立以及维护，只是终端设备有需要的时候，网络设备再向终端设备下发该频点映射关系，从而减少终端设备自行采集的情况；并且避免了由于终端设备初次进入第一小区，并没有预先建立包含有第一小区的频点映射关系的情况下，需要终端设备自行进行扫频再选取第二小区并切换的处理所带来的时延。
一种实施例中，提供了一种终端设备，如图9所示，包括：
第一处理单元51，配置为处于第一小区，发生语音回落时，根据频点映射关系从第二类通信网络中的至少一个第二类小区中确定所要接入的第二小区；其中，所述第一类通信网络与所述第二类通信网络的提供服务的网络节点不同，所述第二类通信网络为终端设备的归属地网络；所述频点映射关系，包括：所述第一类通信网络中的第一类小区，以及与所述第一类小区具备邻区覆盖关系的第二类通信网络的至少一个第二类小区；所述第一类小区中包括所述第一小区；

其中，第一类通信网络的覆盖范围小于第二类通信网络的覆盖范围。具体来说，所述第一类通信网络为5G网络，第二类通信网络为4G网络。
所述第一类通信网络与第二类通信网络的提供服务的网络节点不同，可以理解为第一类通信网络的运营商与第二类通信网络的运营商不同。
本实施例提供的方案，终端设备处于异网漫游情况下，处于与归属地网络不同的运营商提供的第一类通信网络的第一小区(可以称为异网漫游5G小区)中，在当前的5G布网初级阶段，由于针对语音处理通常采用回落方式实现，比如EPS回落，那么就需要将终端设备的通信回落至归属地网络提供的4G小区也就是第二小区中。
具体的实现方式为：终端设备的第一处理单元51通过频点映射关系来确定所要接入的第二小区。
其中，所述频点映射关系可以为预设的，或者可以为网络设备发给终端设备的。当所述频点映射关系为预设的时候，可以由终端设备采集得到。
具体的采集方式可以为：所述终端设备的第一处理单元51建立异网漫游数据库，将至少一个第一类通信网络的第一类小区，以及与所述至少一个第一类小区中每一个第一类小区具备邻区覆盖关系的第二类通信网络的至少一个第二类小区作为所述频点映射关系保存在所述异网漫游数据库中。
进一步地，的第一处理单元51当基于所述频点映射关系，确定与所述第一小区具备邻区覆盖关系的第二类小区为一个时，将所述第二类小区作为所述第二小区；

其中，所述从所述至少两个第二类小区中选取一个作为所述第二小区，可以为，从所述至少两个第二类小区中选取一个作为第二小区，可以根据信号质量进行选取，比如，可以选择信号质量最强的一个作为第二小区。所述参考信号的强度可以通过RSRP、SNR等一个或多个参数来表示，这里不再穷举。
这里，由于本实施例优选针对了第一类小区为5G小区，第二类小区为4G小区的场景，那么关于邻区覆盖关系，需要基于5G小区以及4G小区之间的覆盖特点进行说明：5G小区覆盖范围小于4G小区。通常的情况下，一个4G小区下可以涵盖一个或多个5G小区。比如，如果是边界交叉，则会出现一个5G小区对应两个或者多个4G小区的情况，可以采用信号最强的4G小区作为优先接入小区。

第二通信单元62，配置为向所述终端设备发送所述第二小区的相关信息；所述第二小区的相关信息用于所述终端设备能够由第一小区切换至所述第二小区。
相应的，一种终端设备，包括：
第一处理单元，配置为处于第一小区、且发生语音回落时，接收网络设备发来的第二小区的相关信息；
第一通信单元，配置为基于所述第二小区的相关信息确定所述第二小区、且由第一小区切换至所述第二小区；其中，所述第一小区为第一类通信网络中的第一类小区，所述第二类小区为第二类通信网络中的小区；所述第一类通信网络比第二类通信网络新，并且第一类通信网络与所述第二类通信网络的提供服务的网络节点不同，所述第二类通信网络为终端设备的归属地网络；所述频点映射关系，包括：所述第一类通信网络中的第一类小区，以及与所述第一类小区具备邻区覆盖关系的第二类通信网络的至少一个第二类小区。
其中，第一类通信网络的覆盖范围小于第二类通信网络的覆盖范围。具体来说，所述第一类通信网络为5G网络，第二类通信网络为4G网络。
所述网络设备为第一类通信网络中的基站，优选的为5G网络中的gNB。
本实施例提供的方案，终端设备处于异网漫游情况下，处于与归属地网络不同的运营商提供的第一类通信网络的第一小区(可以称为异网漫游5G小区)中，在当前的5G布网初级阶段，由于针对语音处理通常采用回落方式实现，比如EPS回落，那么就需要将终端设备的通信回落至归属地网络提供的4G小区也就是第二小区中。
具体的实现方式为：终端设备通过网络设备发来的指令完成切换的；其中，网络设备可与预先存储频点映射关系。
本实施例中，与前述实施例不同就在于频点映射关系由网络设备来建立，而不是通过终端设备。

进一步地，网络设备的第二通信单元获取到测试终端上报的内容的方式可以为通过应用层获取。
进一步地，当基于所述频点映射关系，所述网络设备的第二处理单元确定与所述第一小区具备邻区覆盖关系的第二类小区为一个时，将所述第二类小区作为所述第二小区；
当基于所述频点映射关系，所述网络设备的第二处理单元确定与所述第一小区具备邻区覆盖关系的第二类小区为至少两个时，从所述至少两个第二类小区中选取一个作为所述第二小区。

可见，通过采用上述方案，就能够在终端设备在第一类通信网络的第一小区内发生语音回落的时候，基于频点映射关系，确定对应的第二类网络的第二小区，进而终端设备接入到第二小区；其中，第一类通信网络和第二类通信网络为异网，并且第一类通信网络比第二类通信网络新，第二类通信网络可以为终端设备的归属地网络。如此，在终端设备执行语音回落的时候，就避免了由于重新进行扫频再接入归属地网络所带来的时延问题，提升了语音回落处理的切换速度，使得通信网络的处理效率有所提升，并且保证了通信网络的服务质量。
