具体的, 当终端确定业务处于上述状态中的任意一个状态时, 终端 向网络侧设备发送相应的业务状态信息, 以使得网络侧设备获知此时该 业务对应的业务状态, 从而确定调度速率。 步骤 504、 终端将业务状态信息及调度信息发送至所述网络侧设备, 网络设备接收终端发送的调度信息和业务状态信息。
可选的, 终端向网络侧设备发送业务状态信息, 与调度信息一起发 送。 可以将调度信息与业务状态信息封装在报告信息, 在 MAC ( Medium/Media Access Control , 介质访问控制 ) 层或 RRC ( Radio Resource Control , 无线资源控制协调) 层或应用层向网络侧设备发送此 报告。
需要说明的是, 终端可以单独向网络侧设备发送业务状态信息, 本 发明对此不做限定。 需要说明的是, 在本发明所有实施例中, 报告信息中包括的调度信 息可以为一个索引值, 使得网络侧设备接收到报告信息后, 根据报告信 息中的索引值可以获取调度请求速率的范围或请求调度数据量的范围, 根据此调度请求速率的范围确定调度速率。 或根据请求调度数据量的范 围求取相应的请求传输速率的范围, 根据求取的请求传输速率的范围确 定调度速率。 此时, 网络侧设备与终端都预设有相同的索引值和与其相 应的请求传输速率范围或请求调度数据量的范围, 如下表 1和表 2所示, 表 1是不同的调度请求速率对应不同的索引值, 表 2是不同的请求调度 数据量对应不同的索引值。 当然, 报告信息中的调度信息也可以是一个 具体的请求传输速率的值或请求调度数据量的值, 本发明对报告信息中 具体用什么方式包括调度信息不做限定。

终端将此时业务的状态信息及调度信息封装在报告信息中, 发送至 网络侧设备。
网络侧设备接收终端发送的调度信息和业务状态信息。
具体的, 若接收到的为报告信息时, 获取报告信息中记载的业务类 型, 根据此类型, 查看映射信息获取终端发送的业务状态信息。 通过报 告信息中期望速率的索引值, 通过查看映射表可获知对应的调度请求速 率或请求调度数据量。
若分别接收到的为调度信息及业务状态信息, 则根据调度信息可获 知终端期望的传输速率, 根据业务状态信息可获知业务当前所处的状态。
步骤 505、 与步骤 102相同, 在此不再贅述。
步骤 506、 根据确定的所述调度速率为所述终端分配传输资源。

步骤 507、 网络侧设备使用所述传输资源向所述终端发送所述业务 的待传输数据, 终端接收所述网络侧设备发送的所述业务的待传输。
具体的, 确定下行传输资源后, 网络侧设备利用下行传输资源将业 务的待传输数据发送至终端, 终端接收网络侧设备发送的待传输数据。
需要说明的是, 网络侧设备向终端发送待业务数据的速率的级别与 确定的调度速率的级别不同时, 可以将调度速率转换为网络侧设备向终 端发送待业务数据信息的速率的级别。 例如, 网络侧设备向终端发送待 业务数据信息的速率为毫秒级, 调度速率为秒级, 则可以将秒级的调度 速率转换为毫秒级的速率, 根据此毫秒级的速率向终端发送待业务数据。 本发明实施例提供了一种资源调度的方法, 终端向网络侧设备发送 调度信息及业务状态信息, 网络侧设备接收到调度信息及业务状态信息 后, 根据此调度信息、 业务状态信息及预设最大传输速率确定该业务的 调度速率, 并利用此调度速率发送该业务的剩余传输数据信息。 实现了 通过用户端反馈的调度信息得出网络端的发送数据的调度速率, 降低了 网络侧设备以过高或过低的调度速率向终端发送数据的概率, 从而提高 了系统性能, 使得系统的效率提高, 并且进一步减小了用户的等待时间, 从而提高了用户体验。 本发明实施例提供了一种网络侧设备, 该网络侧设备可以是基站、 服务器等网络侧设备, 该网络侧设备可以用于实现上述方法。 如图 7 所 示, 本实施例提供的网络侧设备包括:
