本申请要求了于 2012年 3月 15日提交中国专利局,申请号为 201210068125.9、 发明名称为 "数据包传输方法及系统、 发送端设备与接收端设备" 的中国申 请的优先权, 其全部内容通过引用结合在本申请中。 技术领域 本发明涉及通信系统领域, 特别涉及一种数据包传输方法及系统、 发送 端设备与接收端设备。 背景技术

在现有的无线网络中, 对于某一个特定的业务, RAN承载在无线链路 控制 (Radio Link Control ; RLC ) 层可以釆用两种传输模式: 确认模式 (Acknowledged Mode; AM)和非确认模式 (Un-acknowledged mode; UM)。 在 AM模式下, RLC层釆用自动重传请求 (Automatic Repeat-reQuest; ARQ)机 制传输业务数据, 接收端会对发送端所发送出的每一个数据包进行确认, 以 表示该数据包被正确接收, 该 AM模式应用于对时延要求较低, 而对可靠性要 求较高的业务传输。 在 UM模式下, RLC 层只负责发送、 接收数据包, 并 不对所发送的数据包进行重传,也不对所接收的数据包反馈确认,相对于 AM 模式, UM模式主要应用于对时延要求较高, 对可靠性要求较低的业务。 现有技术中至少存在如下缺点: 无论对于 CN承载还是对于 RAN承载, 还 是在 RAN承载的 AM模式还是 UM模式中,现有的无线网络中釆用的传输方式 均将业务中的不同类型的业务数据对应的数据包集中处理, 导致数据包的处 理效率较低。 发明内容

本实施例的 QoS需求信息包括传输时延优先级级别、 传输可靠性优先级 级别、 丟包指示和紧急指示中的至少一个;
其中传输时延优先级的级别越高, 表示该数据包对时延要求越高, 要求 越小的传输时延; 不同的传输时延优先级级别对应不同的传输过程中的时延 要求。 传输可靠优先级级别越高, 表示该数据包对可靠性要求越高; 不同的 传输可靠优先级级别对应不同的传输过程的可靠性要求。 丟包指示用于表示 该数据包是否可以被丟弃。 紧急指示用以指示该数据包是否属于紧急数据包, 对于紧急的数据包, 在传输路径上的传输设备, 可以先于其他非紧急数据包, 而对该数据包进行传输。
101、 发送端在业务数据对应的数据包中携带 QoS需求信息;
102、发送端向接收端发送携带 QoS需求信息的数据包, 以供接收端根据 QoS需求信息对数据包进行调度处理。
本实施例的数据包传输方法, 通过由发送端根据业务数据的内容或者类 型为业务数据设置 QoS需求信息, 该 QoS需求信息包括传输时延优先级级别、 传输可靠性优先级级别、 丟包指示和紧急指示中的至少一个; 并在向接收端 发送的数据包中携带该 QoS需求信息, 这样接收端便可以根据 QoS需求信息 对接收的该数据包进行调度处理。 釆用本实施例的技术方案, 能够克服现有 技术中所有数据包进行集中处理, 导致数据包的处理效率较低的缺陷, 通过 根据 QoS需求信息对接收的该数据包进行调度处理, 从而能够有效地提高数 据包的处理效率。
可选地,在上述图 1所示实施例的基础上,还可以包括如下可选技术方案, 构成图 1所示实施例的扩展实施例。
在图 1所示实施例的扩展实施例中, 发送端具体可以为网关节点
( Gateway node )或者服务器 (Server ) , 接收端为基站 (如 eNodeB ) 。 此时对应地上述实施例中的步骤 101和步骤 102具体可以包括以下几种情况: 第一种情况: 当业务数据为视频业务数据时, 上述图 1所示实施例中的步 骤 100"发送端在业务数据对应的数据包中携带 QoS需求信息",具体可以包括: 发送端在初始化分段 ( Initialization Segment ) 和 /或媒体分段 ( Media Segment ) 的剩余比特位中携带 QoS需求信息。 这里的 Media Segment即指 的是媒体数据分段。
对应地, 上述图 1所示实施例中的步骤 102"发送端向接收端发送携带 QoS 需求信息的数据包, 以供接收端根据 QoS需求信息对数据包进行调度处理", 具体可以包括: 发送端向接收端发送包括有 Initialization Segment 和 /或 Media Segment的数据包, 以供接收端根据 Initialization Segment 和 /或 Media Segment中携带的 QoS需求信息对包括有 Initialization Segment和 /或 Media Segment的数据包进行调度处理。 其中包括有 Initialization Segment 和 /或 Media Segment的数据包中包含 Initialization Segment 和 /或 Media Segment和数据内容, 其中 Initialization Segment和 /或 Media Segment中携 带有 QoS需求信息。

对应地, 上述图 1所示实施例中的步骤 102"发送端向接收端发送携带 QoS 需求信息的数据包, 以供接收端根据 QoS需求信息对数据包进行调度处理", 具体可以包括: 发送端向接收端发送包括有 Initialization Segment 和 /或 Media Segment的数据包, 以供接收端根据 Initialization Segment 和 /或 Media Segment中携带的 QoS需求信息对包括有 Initialization Segment和 /或 Media Segment的数据包进行调度处理。 进一步可选地, 当上述业务数据为视频业务数据时, 此时对应的 QoS需 求信息中还可以包括帧间依赖信息、 帧的质量信息和层的指示信息中的至少 一个。
其中帧间依赖信息, 用于表示帧间的依赖关系, 即表示该视频数据包是 否被其他数据包所参考, 以及参考程度等信息。 帧的质量信息表示当前数据 包对于视频播放质量的影响的程度信息。 层的指示信息, 用于表示当视频数 据釆用分层编码方式处理时, 指示当前数据包属于基本层数据包、 还是增强 层的数据包。
以视频业务为例, 对于视频的主要关键帧和 /或被参考帧对应数据包设置 较高的传输优先级别, 对于其他不重要或可靠性较低的数据对应的数据包, 可以设置较低的传输优先级别, 这种方式可以保证关键的数据包可以被可靠 的传输给用户, 提升了用户在窄带传输下的观看体验。
以实时视频业务为例, 对于接近绝对播放时间 (实况转播中需要某帧需 要被客户端播放的绝对时间) 的视频数据, 可以设置传输时延为高优先级和 / 或为紧急数据; 否则, 可以设置传输时延为低优先级和 /或不紧急。
以视频业务为例, 对于视频播放所需要关键数据包, 比如: 包含元数据 的数据包, 或被一个或多个帧参考的数据包, 可以设置为不能丟包, 对于普 通的视频数据可以设置为可以丟包。
图 2为本发明实施例提供的一种 Initialization Segment的数据格式图, 图 3 为本发明实施例提供的一种 Media Segment的数据格式图。如图 2和图 3所示, 以在 Initialization Segment和 Media Segment中增力口一个新 t匕特位携带 QoS 需求信息, 例如该 QoS需求信息具体携带传输时延优先级级别、 传输可靠性 优先级级别、 丟包指示和紧急指示中的哪一个可以预先规定。 图 4为本发明实 施例提供的另一种 Initialization Segment的数据格式图, 如图 4所示, 以在 Initialization Segment中增加两个新比特位携带输时延优先级级别和传输可 靠性优先级级别为例。图 4仅为一个可选方案,实际应用中,可以在 Initialization Segment和 Media Segment中传输时延优先级级别、 传输可靠性优先级级别、 丟包指示、 紧急指示、 帧间依赖信息、 帧的质量信息和层的指示信息中的至 少一个, 具体携带哪一个或者几个可以预先设定, 在此不再——举例。
第三种情况: 上述图 1所示实施例中的步骤 100"发送端在业务数据对应的 数据包中携带 QoS需求信息", 具体可以包括: 发送端在通用分组无线业务隧 道协议 ( General Packet Radio Service Tunnelling Protocol; GTP) )数据包 的包头中新增加第一扩展头部信息, GTP数据包中包括业务数据; 发送端在 第一扩展头部信息携带 QoS需求信息。

图 5为本发明实施例提供的一种在 GTP数据包的数据格式图。如图 5所示, 以在图 5的 GTP数据包的包头中新增加第一扩展头部信息, 并在第一扩展头部 信息中增加传输时延优先级级别为例。 实际应用中在该第一扩展头部信息中 具体可以增加传输时延优先级级别、 传输可靠性优先级级别、 丟包指示和紧 急指示中的一个或者多个。 在此不再——举例。
第四种情况: 上述图 1所示实施例中的步骤 100"发送端在业务数据对应的 数据包中携带 QoS需求信息", 具体可以包括: 发送端在网际协议( Internet Protocol; IP )数据包的包头中携带 QoS需求信息;
对应上述图 1所示实施例中的步骤 102"发送端向接收端发送携带 QoS需 求信息的数据包, 以供接收端根据 QoS需求信息对数据包进行调度处理", 具 体可以包括: 发送端向接收端发送携带 QoS需求信息的 IP数据包, 以供接收 端根据 QoS需求信息对 IP数据包进行调度处理。
可选地,在图 1所示实施例的扩展实施例中,发送端具体还可以为基站(如 eNodeB ) , 接收端具体可以为用户设备 ( User Equipment; UE ) 。 此时对 应地上述实施例中的步骤 101和步骤 102具体可以包括以下几种情况:
第一种情况: 上述图 1所示实施例中的步骤 100"发送端在业务数据对应的 数据包中携带 QoS需求信息", 具体可以包括: 发送端在分组数据汇聚协议 ( Packet Data Convergence Protocol; PDCP )数据包的包头中新增加第二 扩展头部信息, PDCP数据包中包括业务数据; 发送端在第二扩展头部信息携 带 QoS需求信息。
对应上述图 1所示实施例中的步骤 102"发送端向接收端发送携带 QoS需 求信息的数据包, 以供接收端根据 QoS需求信息对数据包进行调度处理", 具 体可以包括: 发送端向接收端发送携带 QoS需求信息的 PDCP数据包, 以供接 收端根据 QoS需求信息对 PDCP数据包进行调度处理。
图 6为本发明实施例提供的一种在 PDCP数据包的数据格式图。 如图 6所 示, 以在 PDCP数据包的包头中新增加第二扩展头部信息, 并在第二扩展头部 信息中增加传输时延优先级级别和传输可靠性优先级级别为例, 例如具体可 以在 PDCP 数据包的包头中新增加至少一个扩展头的指示 E, 用于指示是 否使用扩展头信息和 /或扩展头的类型。 例如图 6中的扩展头指示 E用于指示当 前 PDCP数据包包头中携带有 QoS需求信息的头部信息的扩展。 其中 D/C 指 示: 0表示数据, 1表示控制信息; R表示保留; E表示扩展头指示。其中 PDCP 数据包的序号分为两行, 第一行为 4bit, 第二行为 8bit。
第二种情况: 上述图 1所示实施例中的步骤 100"发送端在业务数据对应的 数据包中携带 QoS需求信息", 具体可以包括: 发送端在无线链路控制( Radio Link Control; RLC )协议数据包的包头中新增加第三扩展头部信息, RLC协 议数据包中包括业务数据; 发送端在第三扩展头部信息携带 QoS需求信息。
对应上述图 1所示实施例中的步骤 102"发送端向接收端发送携带 QoS需 求信息的数据包, 以供接收端根据 QoS需求信息对数据包进行调度处理", 具 体可以包括: 发送端向接收端发送携带 QoS需求信息的 RLC协议数据包, 以 供接收端根据 QoS需求信息对 RLC协议数据包进行调度处理。
实际应用中, 发送端中可以设置有传输时延优先级阔值和传输可靠优先 级阔值, 发送端可以对大于传输时延优先级阔值、 大于传输可靠优先级阔值、 没有丟包指示以及有紧急指示的数据包设置携带 QoS需求信息, 而不用在每 个数据包中都携带 QoS需求信息, 该方式有助于降低系统的带宽资源开销。 例如在大于传输时延优先级阔值、 大于传输可靠优先级阔值、 没有丟包指示 以及有紧急指示的数据包中携带 QoS需求信息, 而在小于传输时延优先级阔 值、 小于传输可靠优先级阔值、 有丟包指示以及没有紧急指示的数据包中不 携带 QoS需求信息, 当接收端接收到未携带有 QoS需求信息的数据包, 则将 该数据包按照 QoS需求信息指示的低优先级方式处理。 反之亦然, 在此不再 赘述。 对于帧间依赖信息、 帧的质量信息和层的指示信息的情况类似, 在此 亦不再赘述。
比如: 当发送端判断关键帧数据包的丟包率要低于 10—6, 而非关键帧数据 包的丟包率可以高于 10-6,则发送端可以设置关键帧的数据包为高可靠性级别 的数据包, 而对非关键帧的数据包不设置可靠性级别, 当接收端接收到携带 有高优先级的数据包时, 则按照高优先级数据包处理, 当接收端接收到没有 携带有高优先级得数据包时, 则按照非高优先级数据包处理。
上述实施例的数据包传输方法, 通过由发送端根据业务数据的内容或者 类型为业务数据设置 QoS需求信息, 该 QoS需求信息包括传输时延优先级级 别、 传输可靠性优先级级别、 丟包指示和紧急指示中的至少一个; 并在向接 收端发送的数据包中携带该 QoS需求信息, 这样接收端便可以根据 QoS需求 信息对接收的该数据包进行调度处理。 釆用上述实施例的技术方案, 能够克 服现有技术中所有数据包进行集中处理, 导致数据包的处理效率较低的缺陷, 通过根据 QoS需求信息对接收的该数据包进行调度处理, 从而能够有效地提 高数据包的处理效率。
图 7为本发明另一实施例提供的数据包传输方法的流程图。 如图 7所示, 本实施例的数据包传输方法, 具体可以包括如下步骤:
200、 接收端接收发送端发送的携带 QoS需求信息的数据包;
本实施例中的 QoS需求信息为发送端根据业务数据的内容或者类型确定 的, QoS需求信息包括传输时延优先级级别、 传输可靠性优先级级别、 丟包 指示和紧急指示中的至少一个。
201、 接收端根据 QoS需求信息对数据包进行调度处理。
本实施例的数据包传输方法与上述图 1所示实施例的区别仅在于: 上述图 1所示实施例的数据包传输方法在发送端侧描述本发明的技术方案, 而本实施 例在接收端侧描述本发明的技术方案, 详细可以参考上述图 1所示实施例的记 载, 在此不再赘述。

进一步可选地, 当业务数据为视频业务数据时, QoS需求信息还包括帧 间依赖信息、 帧的质量信息和层的指示信息中的至少一个。
可选地, 当接收端为基站时, 此时对应地步骤 201 "接收端根据 QoS需求 第一种方式: 基站根据 QoS需求信息对该数据包釆用增加混合自动重传 请求( Hybrid Automatic Repeat Request; HARQ )的重传次数的方式进行传 输, 比如: 当基站接收到携带有高可靠优先级信息的数据包时, 基站可以增 加高优先级的数据包的重传次数, 进而增加该数据包的传输可靠性;
第二种方式: 基站根据 QoS需求信息对该数据包釆用釆用高可靠性的低 阶的调制编码方式(Modulation Coding Scheme; MCS )传输;
第三种方式: 基站根据 QoS需求信息对该数据包的传输提升发送功率; 第四种方式:基站根据 QoS需求信息提高当前 UE 的调度优先级, 比如: 当基站接收到携带有高时延优先级信息的数据包时, 基站可以提高当前服务 的 UE 或数据的调度优先级别, 优先调度该数据包;
第五种方式:基站根据 QoS需求信息,确定除非该数据包被 UE成功接收, 否则该数据包不能被丟弃, 比如: 当基站接收到携带有不允许丟包指示的数 据包时, 不能由于该数据包緩存时间过长而丟弃该数据包, 直到该数据包被
UE接收到。 以上几种方式仅为举例, 实际应用中除了上述情况还可以釆用其他扩展 方式进行数据包传输, 在此不再——列举。
可选地,在图 7所示实施例的扩展实施例中 ,发送端具体还可以为基站(如 eNodeB ) , 接收端具体可以为 UE。 此时对应地上述实施例中的步骤 200具体 可以包括以下几种情况:

可选的,基站中的 PDCP 实体可以按照数据包所对应的 QoS需求信息发 送数据给 UE, 例如, PDCP数据包对应高传输可靠性优先级时, 基站中的 PDCP实体在将该 PDCP数据包发送给底层后,如果接收到底层的传输失败确 认,或没有接收到传输成功确认,则重发该 PDCP数据包。再例如: 当将 PDCP 数据包发送给底层时, 启动一个基站预配置的重传定时器, 在该重传定时器 超时之前, 仍然没有得到对应该 PDCP数据包的接收成功的响应, 则重传该 PDCP数据包。 相反如果 PDCP数据包对应低传输可靠性优先级, 则在丟弃 PDCP数据包时, 不需要等待接收底层的传输成功确认。
第二种情况: 接收端接收发送端发送的携带 QoS需求信息的 RLC协议数 据包, QoS需求信息携带在 RLC协议数据包的包头中新增加的第三扩展头部 信息中。
可选地, 当接收端为 UE时, 此时对应地步骤 201"接收端 居 QoS需求 信息对数据包进行调度处理 "具体可以包括: UE接收到数据包, 并将该数据 包递交给上层应用, 例如 UE可以按照数据包中所携带的 QoS需求信息, 按 照 QoS需求信息的指示, 将数据包递交给上层。
例如如果该数据包中指示为紧急数据包和 /或传输时延高优先级数据包, 则 UE可以直接递交该数据包,而不用等待接收到之前的乱序数据包后才按序 递交, 这样能够根据数据包的 QoS需求信息对该数据包进行及时处理, 有效 地提高数据包的处理效率。 例的扩展实施例的区别仅在于: 上述图 1所示实施例的扩展实施例中的数据包 传输方法在发送端侧描述本发明的技术方案, 而图 7所示实施例的扩展实施例 在接收端侧描述本发明的技术方案, 详细可以参考上述图 1所示实施例的扩展 实施例的记载, 在此不再赘述。
