实施例一
图 1为本发明实施例一所提供的业务数据无线传输方法的流程图。 该 方法由优化网络中配置的业务数据无线传输装置执行, 该装置通常以硬件 和 /或软件的方式来实现,例如该传输装置可以配置在业务优化网关之中执 行传输方法。 如图 1所示, 本实施例的业务数据无线传输方法, 具体可以 包括如下: 5101、 业务优化网关接收基站发送的带宽信息报告。 其中, 所述带宽 信息报告中携带有所述基站可接纳的业务带宽。
所述业务带宽通常为所述基站可以提供给被请求业务数据传输用的 带宽, 需要依据所述基站的服务、 负载情况来决定, 因此需要所述基站将 其可以提供的带宽报告给所述业务优化网关, 以实现所述基站和业务优化 网关之间带宽信息的交流, 使得所述基站根据自身能力预测的业务带宽需 求与所述业务优化网关所分配的业务带宽更匹配。 因为现有技术是按照一 定时间内用户设备接收到的所述被请求业务数据来预测未来基站可以提 供的带宽, 而用户设备并不了解网络的实际情况, 导致业务带宽估计可能 有误; 本发明实施例是根据业务速率要求所述基站来提供匹配的业务带 宽, 相比于现有技术中的用户设备进行业务带宽估计, 本发明实施例的方 法更加准确。 例如, 对于视频数据这种业务数据而言, 其速率可体现为码 率。 所述码率即把每秒显示的视频进行压缩后的数据量, 一般釆用的单位 是千位每秒 ( kilobits per second, 简称 kbps ) 。
所述基站, 可以是码分多址 ( Code Division Multiple Access , 简称:
CDMA ) 系统中的基站 ( Base Transceiver Station, 简称: BTS ) , 也可以 是宽带码分多址 ( Wideband Code Division Multiple Access, 简称:
WCDMA ) 系统中的基站 (NodeB ) , 还可以是长期演进( Long Term Evolution , 简称: LTE ) 系统中的演进型基站 ( Evolutional Node B , 简称: eNB或 eNodeB ) , 本发明并不限定。
5102、 根据所述业务带宽确定与所述业务带宽匹配的业务数据。
现有技术中是通过用户设备完成对所述被请求业务数据的选择, 而在 本发明实施例是通过所述业务优化网关根据所述基站的负载信息等来确 定与所述业务带宽匹配的业务数据, 自动进行业务数据的码率调整来适应 业务带宽。
5103、 将确定的所述业务数据发送给基站。
本实施例,通过在网络侧部署业务优化网关,提供被请求的业务数据, 基站根据自身能力预测, 识别出能够保障业务流畅执行的所述业务数据, 例如, 对于视频业务, 可避免视频播放过程中用户设备緩冲区内容过少而 导致的视频播放停顿, 实现用户业务体验的提升。 实施例二

S202、 业务优化网关接收所述基站反馈的是否支持带宽信息报告的指 示消息。
具体地, 在所述业务优化网关不确定所述基站是否支持本发明所提供 的带宽信息报告的方法时, 可以由所述业务优化网关通过发送所述带宽报 告能力查询消息的形式查询所述基站的带宽报告能力。 其中, 指示消息可 以分为支持带宽信息报告的指示消息和不支持带宽信息报告的指示消息。 当所述基站接收到所述带宽报告能力查询消息后, 若支持所述带宽信息报 告, 则所述基站发送所述支持带宽信息报告的指示消息给所述业务优化网 关; 否则, 所述基站发送所述不支持带宽信息报告的指示消息或异常指示 消息给所述业务优化网关。
本实施例, 通过首先检测基站是否支持带宽信息报告的能力, 在所述 基站和业务优化网关之间执行所述基站带宽能力的协商, 从而避免在所述 基站不支持带宽信息报告的能力时, 还要继续执行本发明所提供的业务数 据无线传输方法, 进而避免无线传输过程中时间的浪费。
