在终端在第一单模无线通信系统上传输的业务包括两种或两种以上 业务类型的实施场景下，第一无线接入网设备可以为终端确定将该两种或两 种以上业务类型的业务数据分别在多模无线通信系统中包括的至少两个无线 通信系统中传输， 其中， 每个无线通信系统中传输哪种业务， 或者传输哪种 业务的数据量可以由第一无线接入网设备根据各无线通信系统的链路质量， 终端的业务数据量， 业务类型等因素来确定。 举例来说， 第一无线接入网设 备可以确定终端在链路质量较高的无线通信系统上传输视频业务， 可以确定 终端在链路质量相对较差的无线通信系统上传输语音业务。 第一无线接入网 设备可以在第一控制信息中携带指示信息 , 通过指示信息来指示终端的哪种 业务在哪个无线通信系统上传输。
在终端通过无线接入网设备确定的多模无线通信系统传输业务之后， 可选的， 第二无线接入网设备还可以根据终端在多模无线通信系统上的业务 传输状况， 为终端确定用于业务传输的第二单模无线通信系统。
在多模无线通信系统中包括第一单模无线通信系统的实施场景下， 第 二无线接入网设备可以为第一单模无线通信系统中的 RAN侧设备， 例如： 可以为第一设备； 在多模无线通信系统中不包括第一单模无线通信系统的 实施场景下， 第二无线接入网设备可以为多模无线通信系统中的任一无线 通信系统中的 RAN侧设备。
其中， 终端在多模无线通信系统上的业务传输状况可以包括以下一种或 多种组合： 多模无线通信系统中包括的至少两个无线通信系统的链路质 量， 多模无线通信系统中包括的所述至少两个无线通信系统的緩存空闲 率， 多模无线通信系统中包括的至少两个无线通信系统的分流阈值， 分流 阈值根据无线通信系统的特性设置。
第二无线接入网设备可以通过与多模无线通信系统中的各无线通信系 统中的网元，例如： RAN侧设备进行交互来获取多模无线通信系统中的各 无线通信系统的链路质量， 或者， 还可以由终端对多模无线通信系统的链 路质量进行检测， 再将检测结果上报给第二无线接入网设备。 第二无线接 入网设备可以通过与多模无线通信系统中的各无线通信系统中的网元交互 来获取多模无线通信系统中的各无线通信系统的緩存空闲率和分流阈值。 其中， 分流阈值可以根据无线通信系统的特性设置， 分流阈值越高， 则相 对可以传输的数据量越小。
举例来说， 如果第二无线接入网设备通过与多模无线通信系统中的各 无线通信系统中的网元的交互获知多模无线通信系统中某一个或多个无线 通信系统的緩存空闲率低于设定的緩存门限， 则第二无线接入网设备可以为 终端确定用于业务传输的第二单模无线通信系统； 再比如， 如果第二无线接 入网设备通过与多模无线通信系统中的各无线通信系统中的网元的交互 获知多模无线通信系统中某一个或多个无线通信系统的链路质量低于设定的 质量门限， 则第二无线接入网设备可以在多模无线通信系统中为终端确定链 路质量较好的第二单模无线通信系统， 或者， 在多模无线通信系统之外的无 线通信系统中为终端确定第二单模无线通信系统。 再比如， 多模无线通信系 统中的 UMTS由于其资源瓶颈， 难于承担大流量数据传送， 具有较大的分 流阈值， 因此， 应避免由于传送大流量数据而使 UMTS链路发生拥塞， 当 UMTS 上传输的业务数据量较大时， 第二无线接入网设备可以确定 UMTS 不再为终端传输业务。
上述仅为无线接入网设备为终端确定用于业务传输的第二单模无线通 信系统的几种可行实施方式， 但并不以此作为对本申请的限制。
可以理解的是， 对于第二单模无线通信系统具体为哪个无线通信系 统， 第二无线接入网设备还可以根据各无线通信系统的链路质量， 业务承载 类型和能力， 緩存空闲率等来确定。 举例来说， 第二无线接入网设备可以确 定链路质量较好的无线通信系统作为第二单模无线通信系统； 再比如， 第二 无线接入网设备可以确定緩存空闲率较高的无线通信系统作为第二单模无线 通信系统。
