下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
应注意，本发明实施例中的无线接入技术也可以称为无线技术，包括但不限于俗称为4G的长期演进(Long Term Evolution，LTE)、无线局域网(Wireless LAN，WLAN)、未来5G等。
应注意，本发明实施例中的终端可以是指移动终端，包括但不限于蜂窝电话、个人数字助手(Personal Digital Assistant，PDA)、未来5G网络中的终端设备等。
应注意，本发明实施例中的网络设备可以是用于集中管理和控制多个基地台的基地台控制器或基地台服务器，也可以是用于与多个基地台相互通信的移动性管理实体(Mobility Management Entity，MME)等，本发明对此不作限定。
应注意，本发明实施例中的终端和网络设备都支持多种无线接入技术。并且，多种无线接入技术可以独立使用或共享使用相同的软硬件资源，这里的软硬件资源可以包括天线、射频模块、基带模块、处理器、存储系统、用户界面等。当共享使用相同的软硬件资源时，多种无线接入技术可以单独使用或同时使用相同的软硬件资源。
图1是本发明一个实施例的业务传输的方法的流程图。图1中示出了终端11和网络设备12。图1所示的方法包括：
S101，网络设备12获取多种无线接入技术的网络能力。
具体地，网络设备12可以从多种无线接入技术的多个基地台获取网络能力。
例如，对于多种无线接入技术中的无线接入技术RAT1，网络设备12可以从无线接入技术RAT1的多个基地台获取无线接入技术RAT1的网络能力。
本发明实施例中，网络能力可以包括峰值速率、延迟时间、覆盖范围、系统负载和平均吞吐量等中的一项或多项。
其中，覆盖范围可以与基地台的发射信号的强度和质量有关，也可以与基站的接收灵敏度有关。例如，可以将能够接收到的基地台BS1的发射信号的强度大于一个固定值的区域作为基地台BS1的覆盖范围。其中，峰值速率、延迟时间(也称为传输时延)和平均吞吐量可以统称为传输能力。其中，系统负载也可以称为网络负载。本发明对此不作限定。
另外，网络能力还可以包括所支持的业务类型(Type of Service，ToS)。一般地，业务类型可以为实时业务或非实时业务。例如，实时业务可以为：双边和多边语音/视频通信及会议、交互式在线游戏、智能交通等。非实时业务可以为：文件传输、视频观看等。
S102，网络设备12将多种无线接入技术的网络能力发送至终端11。
具体地，网络设备12可以是发送广播消息，广播消息包括多种无线接入技术的网络能力。也就是说，网络设备12可以通过广播的形式发送多种无线接入技术的网络能力。
这里的多种无线接入技术可以是网络设备12所在的区域内的所有的无线接入技术。
可理解，S102是指网络设备12广播所在区域内的各种无线接入技术的网络能力。
可选地，网络设备12可以在一个广播消息中发送多种无线接入技术的网络能力，例如，可以在单独的信令载频上发送。或者，网络设备12可以在多个广播消息中分别发送多种无线接入技术的网络能力。
可选地，作为一个实施例，图1中的S101和S102可以由下述步骤S101’(图1中未示出)代替实现：
S101’，与多种无线接入技术对应的多个基地台分别将各自的无线接入技术的网络能力发送至终端11。
举例来说，可以以广播的形式发送网络能力。
例如，以多种无线接入技术中的无线接入技术RAT2为例，无线接入技术RAT2的多个基地台广播发送无线接入技术RAT2的网络能力。
例如，可以是网络设备12(如基地台控制器、或基地台服务器或MME)指示多个基地台分别进行发送。也就是说，可以是多个基地台分别发送广播消息，并且每个基地台发送的广播消息包括对应的无线接入技术的网络能力。
并且，相邻区域的广播消息可以在时间或频率或时频二维分布上分开，这样，位于区域交界处的终端可以接收到多个区域的广播消息。
这样，在S101和S102之后，或者在S101’之后，终端11在接收到多种无线接入技术的网络能力之后，可以获知终端11的周边网络所支持的无线接入技术的种类等信息。
S103，终端11从所述多种无线接入技术中为所述终端11的业务选择至少两种无线接入技术。
具体地，终端11可以根据接收到的所述多种无线接入技术的网络能力，从所述多种无线接入技术中选择至少两种无线接入技术。
这里的业务可以是终端11内即将要启动的业务，即S103可以是在终端11准备发起业务时执行的。
可理解，终端11中可以包括多个业务，那么，终端11为每个业务分别执行S103选择的过程。
具体地，终端11可以根据网络能力、业务的业务需求、终端11的特性以及终端11所处的网络条件，选择至少两种无线接入技术。
例如，终端11可以为语音和/或视频通信业务，以及不希望被打断的交互式在线游戏业务选择具有连续覆盖和完善移动性的蜂窝网络(2G，3G，LTE等)。如果终端11处于高速WLAN热点的覆盖范围内，则可以为大数据量数据传输类业务，如视频播放、文件上传和下载等，选择高速WLAN；如果终端11在移动过程中离开了高速WLAN的覆盖范围，则所述大数据量数据传输类业务可以暂停直到终端11再次进入高速WLAN的覆盖范围。
如果终端11处于非静止状态，即终端11处于运动状态，终端11还要结合网络能力的变化，选择至少两种无线接入技术。也就是说，如果终端11处于运动状态，那么终端11可以根据网络能力、业务的业务需求、终端11的特 性、终端11所处的网络条件以及网络条件的变化状态，选择至少两种无线接入技术。
其中，业务的业务需求可以包括业务的数据量、业务的业务类型、业务的可靠性要求、业务的即时性要求、业务的服务质量(Quality of Service，QoS)需求等中的一项或多项。其中的业务类型可以为语音、视频、下载、在线游戏、在线导航、浏览、即时消息等。
其中，终端11的特性可以包括终端的中央处理单元(Central Processing Unit，CPU)的占用率、存储器的占用率、电池消耗速度、电池剩余电量、终端的温度以及用户偏好设置等中的一项或多项。
可理解，终端11包括处理器和存储器等，处理器可以为CPU。占用率可以用百分比表示，例如，CPU的占用率可以为1％，存储器的占用率可以为12％等等。电池剩余电量也可以用百分比表示，例如，电池剩余电量可以为50％。电池消耗速率可以用单位时间消耗的电量百分比表示，例如，电池消耗速率可以为10％/h，h表示小时。终端的温度可以用CPU的温度表示。用户偏好设置可以是用户预设置的(可以是手动设置的)，可以是业务传输时所使用的无线接入技术的数量的上限；例如，用户偏好设置可以为高性能模式或节能模式等，或者，用户偏好设置可以是业务A所使用的RAT的数量上限为4。
其中，终端11所处的网络条件可以包括：终端11所能接收到的多种无线接入技术的基地台的发射信号的强度和质量、终端11具备的多种无线接入技术的最大发射功率和天线增益、终端11具备的多种无线接入技术的接收灵敏度、终端11在所述多种无线接入技术上的传输能力等中的一项或多项。
其中，终端在多种无线接入技术上的传输能力可以包括峰值速率、平均吞吐量、传输延迟等。
其中，如果终端11处于非静止状态，那么，终端11所处的网络条件的变化可以与终端11与目标设备之间的距离的变化和/或终端11的移动速度有关。
那么，可理解，在S103之前，可以包括：终端11计算终端11所处的网络条件，并可选地，可将将该终端11所处的网络条件告知网络设备12。
具体地，终端11可以从网络设备12获取终端11的位置信息，再根据该位置信息计算网络条件。
例如，网络设备12可以预先存储或者随时获取与多种无线接入技术对应的多个基地台的位置。多个基地台可以计算出终端11与多个基地台之间的距离，并将该距离信息发送至网络设备12。
那么，网络设备12在从与多种无线接入技术对应的多个基地台获取终端11与所述多个基地台之间的距离信息之后，便可以根据该距离信息和多个基地台的位置，进行联合定位，从而确定终端的位置信息。
举例来说，终端11/网络设备12可以综合多个基地台发送的距离信息，得到该终端11的位置的精确结果。
另一方面，如果终端11处于非静止状态，即该终端11处于运动状态，在S103之前，还可以包括：终端11记录终端11自己的移动速度并将该移动速度告知网络设备12，或者网络设备12主动检测终端11的移动速度。随后，网络设备12可以根据终端11的位置信息以及该移动速度，利用覆盖地图等信息估计终端11的可能的活动轨迹，进一步根据该可能的活动轨迹告知终端11。
举例来说，如图2所示，示出了终端11、网络设备12，以及多种无线接入技术(假设为三种无线接入技术)的基地台分别为21至26。那么，终端11可以根据在S102中从网络设备12接收到的网络能力或者在S101’中从多个基地台接收到的网络能力，结合终端11的移动情况，判断出多种无线接入技术的网络能力的变化情况，例如，各种无线接入技术的基地台的发射信号的变化情况，进而选择至少两种无线接入技术。
例如，如果终端11接收到第一无线接入技术的各个基地台的发射信号的强度都大于预设的第一信号阈值，那么终端11可以选择该第一无线接入技术。虽然终端11接收到第二无线接入技术的基地台的发射信号小于预设的第二信号阈值，但终端11判断出该终端11正在接近该第二无线接入技术的某个基地台，那么终端11也可以选择该第二无线接入技术。
可理解，其中，第一信号阈值与第一无线接入技术的属性有关，第二信号阈值与第二无线接入技术的属性有关。
可选地，作为一个实施例，终端11可以统计所述多种无线接入技术的能量消耗的速率，并进一步根据网络能力和能量消耗的速率，从所述多种无线接入技术中选所述至少两种无线接入技术。
具体地，终端11可以根据网络能力和能量消耗的速率，并结合前面所描述的终端的特性、终端所处的网络条件、业务需求等，为业务选择至少两种无线接入技术。
这里，所述能量消耗的速率可以包括：射频与中频的能量消耗的速率以及数字信号处理的能量消耗的速率。能量消耗的速率可以以单位比特的能量消耗量表示，例如a焦耳/bit。其中，射频与中频的装置如功率放大器、滤波器、混频器、振荡器、射频中频开关等。数字信号处理的装置如计算单元、存储单元、输入输出(Input/Output，I/O)单元等。
应注意，本发明实施例对S103中终端11选择至少两种无线接入技术的方式不作限定。
S104，为至少两种无线接入技术建立连接。
可选地，在S103之后，终端11自主地为所述至少两种无线接入技术建立连接，并且在建立连接之后告知与至少两种无线接入技术对应的至少两个基地台。
可选地，在S103之后，终端11可以向与至少两种无线接入技术对应的至少两个基地台发送建立请求消息，以使所述至少两个基地台建立连接。
也就是说，在S104中的连接的过程可以是由终端11自主发送执行的，也可以是由终端11告知基地台后由基地台执行的，本发明对此不作限定。
应注意，在连接之后，终端11和网络设备12可以为至少两种无线接入技术中的每种无线接入技术选择合适的发射/接收频率、发射/接收时间和发射功率，以避免不同的无线接入技术之间的相互干扰。
S105，终端11通过所述至少两种无线接入技术进行所述业务的传输。
具体地，终端11可以使用分集模式和/或聚合模式，通过所述至少两种无线接入技术进行所述业务的传输。
其中，分集(diversity)模式是指不同的无线接入技术传输同样的内容，例如，数据包D1使用第一无线接入技术和第二无线接入技术分别进行传输，即表示数据包D1由第一无线接入技术和第二无线接入技术采用分集模式进行传输。这样能够提高业务传输的可靠性。
聚合(aggregation)模式是指不同的无线接入技术传输不同的内容，例如， 第一无线接入技术传输数据包D1，第二无线接入技术传输数据包D2，即表示第一无线接入技术和第二无线接入技术采用聚合模式进行传输。这样能够提高业务传输的速率。
使用分集模式和聚合模式的混合模式，是指业务的部分数据包由几种无线接入技术采用分集模式进行传输，业务的某些数据包由几种无线接入技术采用聚合模式分别进行传输。例如，假设第一无线接入技术传输数据包D1和数据包D2，第二无线接入技术传输数据包D1，第三无线接入技术传输数据包D3，则说明数据包D1由第一无线接入技术和第二无线接入技术采用分集模式进行传输，且第一无线接入技术和第三无线接入技术采用聚合模式分别传输数据包D2和数据包D3。
在S105的业务传输的过程中，终端11可以随时监控各种参数的变化情况，并根据变化情况相应地调整多种无线接入技术。这样，能够保障业务的传输质量和传输效率。
作为一例，如果终端11的电池剩余电量低于电池阈值(例如10％)，或者电池消耗速度高于速度阈值(例如30％/h)，此时，终端11可以切换至使用低能耗的无线接入技术，或者终端11可以减少所使用的无线接入技术的数量。也就是说，针对至少两种无线接入技术中的高能耗的无线接入技术，终端11可以断开连接，只使用至少两种无线接入技术中的低能耗的无线接入技术进行业务传输；或者，可以重新选择低能耗的无线接入技术并建立连接以进行业务传输。
在S105的业务传输的过程中，终端11可以随时(定时地或周期性地)检测所述至少两种无线接入技术的状态。作为一例，如果由于终端11的移动等原因导致至少两种无线接入技术中的某种或某些无线接入技术的信号的强度或质量太差，可以进行断开连接操作。
举例来说，若由于终端11移动使得终端11接收到第一无线接入技术的所有基地台的信号的强度低于预设的第一阈值时，断开该第一无线接入技术的连接。其中，可以是由终端11主动断开连接，也可以是终端11向第一无线接入技术的基地台发送断开请求消息之后，由第一无线接入技术的基地台断开连接。
应注意，本发明实施例中，在有网络覆盖的情况下，终端11应该为活动的业务随时保持一种以上的无线接入技术可用。
举例来说，在S105中业务传输的过程中，若由于N种无线接入技术中的某种或某些无线接入技术断开，导致业务传输的无线接入技术的数量小于预设的阈值(例如为3)，那么，在业务传输过程中，终端11可以为活动的业务继续执行S103和S104的过程。
具体地，在业务传输过程中重新选择无线接入技术时，除了上述S103中所示的因素外，终端11还需考虑该业务在传输过程中的变化情况。例如，该变化情况可以包括终端11与该业务的目标设备之间的距离的变化情况、该业务的剩余数据量等。
可选地，本发明实施例中，如果所有的无线接入接入都不能满足该业务的服务质量需求，那么，终端11可以向用户发出告警信息，例如在终端11的用户界面呈现特定的错误代码，以便于用户根据该告警信息选择终止业务或者降低业务的服务质量需求。
或者，如果所有的无线接入接入都不能满足该业务的服务质量需求，那么，终端11可以将该业务终止，并向用户发送错误信息，例如在终端11的用户界面呈现特定的信息，以便于用户获知该业务已经终止。这样，用户可以在后续的网络状态更佳的情况下，重新尝试该业务的传输。
可选地，本发明实施例中，如果在S105之后，即业务传输结束之后，终端11可以对所述至少两种无线接入技术断开连接。
应注意，本发明实施例中所传输的业务不仅可包括数据业务，也可以是控制信令等。
这样，本发明实施例中，由终端11为业务选择至少两种无线接入技术，能够避免用户手动地设置，从而能够提高多无线接入技术的性能和便利性。并且，在业务传输的过程中，终端11检测至少两种无线接入技术的状态，能够保障业务的传输。
图3是本发明另一个实施例的业务传输的方法的流程图。图3所示的方法包括：
S201，终端接收多种无线接入技术的网络能力。
S202，终端根据所述网络能力，从所述多种无线接入技术中为所述终端的业务选择至少两种无线接入技术。
S203，终端使用所述至少两种无线接入技术进行所述业务的传输。
本发明实施例中，由终端为业务选择至少两种无线接入技术，能够避免用户手动地设置，从而能够提高多无线接入技术的性能和便利性。
可选地，所述多种无线接入技术可以是网络设备发送的，S201可以包括：接收所述网络设备发送的广播消息，所述广播消息包括所述多种无线接入技术的网络能力。
或者，S201可以包括：接收每种无线接入技术的基地台广播发送的对应的无线接入技术的网络能力。
其中，所述网络能力可以包括以下中的至少一项：峰值速率、延迟时间、覆盖范围、系统负载和平均吞吐量。
图3中的S201可以参见图1的实施例中S102或S101’的描述，为避免重复，这里不再赘述。
