技术领域
本发明涉及通信技术领域,特别涉及一种在无线通信系统中实现视频业务 的方法及网元设备。 背景技术
在包交换的移动通信系统中, 通过 IP连接来承载各种视频业务已成为该 系统中的典型应用。 视频业务包括多种数据流, 例如, 视频流、 音频流、 字幕 流等。 其中, 视频流包括: 携带场景关键信息的 I帧和携带场景辅助信息的 P 帧。 在包交换的移动通信系统中, 通常有两种方式来承载视频业务, 一种方式 为: 通过一个连接来传递整个视频业务, 即该视频业务中的视频流、 音频流和 字幕流都在一个业务流中传输, 例如, IPTV ( Internet Protocol Television, 基 于 IP协议的电视广播)和 Mobile TV (移动电视广播)业务中通常使用 TS ( Transport Stream, 传输流)协议在一个连接中传输; 另一种方式为: 通过多 个连接来传递整个视频业务,使用不同的业务流来承载不同类型的数据流,即, 视频流和音频流等不同类型的数据流分别承载在不同的连接上。
在现有的包交换的移动通信系统中,对于通过一个业务流来传递整个视频 业务的方式, 无线通信网络将视频业务作为一个整体设定 QoS ( Quality of Service, 服务质量)参数, 按照设定的 QoS参数进行资源分配。 对于多个业 务流来传递视频业务的方式, 无线通信网络分别设定各数据流的 QoS参数, 按照设定的 QoS参数进行资源分配。
在对现有技术的研究和实践过程中 , 发明人发现现有技术存在以下问题: 现有技术中无线通信网络将视频业务作为一个整体,无法区分不同类型的 数据流, 也不了解视频业务内部不同数据流的具体 QoS需求, 因此, 只能按 照设定的 QoS参数进行调度和资源分配, 无法满足视频业务不同类型数据流 的具体 QoS要求, 影响视频业务的服务质量, 例如会出现图像模糊、 图像晃 动、 马赛克等问题。 对于多个业务流传递视频业务的方式,无法区分数据流中不同的数据帧类 型, 也不了解数据流内部不同类型数据帧的具体 QoS需求, 因此, 只能按照 为各数据流设定的 QoS参数进行调度和资源分配, 无法满足数据流中不同类 型数据帧的具体 QoS要求, 影响视频业务的服务质量, 例如会出现图^^莫糊、 图像晃动、 马赛克等问题。
发明内容
本发明实施例要解决的技术问题是提供一种在无线通信系统中实现视频 业务的方法及网元设备, 能够提高视频业务的服务质量。
有鉴于此, 本发明实施例提供:

本发明实施例通过获取业务流中所包含的数据帧类型参数,从业务流中解 析出各种类型的数据帧; 通过获取业务流中各种类型数据帧的服务质量 QoS 参数, 进而能对各种类型数据帧进行资源分配, 因此, 对于多个业务流传递视 频业务的方式,可以区分某个业务流中不同类型的数据帧, 能够满足该业务流 中不同类型数据帧的具体 QoS要求, 提高视频业务在移动通信网络中的服务 质量; 同理, 对于一个业务流传输视频业务的方式, 该业务流中传输该视频业 务的多种类型数据帧,采用本发明实施例的技术方案可以区分视频业务不同类 型的数据帧, 能够满足不同类型数据帧的具体 QoS要求, 提高视频业务在移 动通信网络中的服务质量。

为使本发明提供的技术方案更加清楚明白, 先对视频业务进行简单描述。 一个完整的视频业务包括: 多种数据流, 例如, 视频流、 音频流、 字幕流等。 其中, 每一种数据流的具体 QoS要求可能会有所不同, 比如, 音频流的 QoS 要求与普通的电路语音和 IP语音接近, 误包率通常在 1 %左右, 如果是高保 真的数字音频解码, 则可能要求更高; 字幕流的 QoS要求一般比音频流和视 频流低。 而对于同一数据流中的不同类型数据帧, 其 QoS要求也可能不同, 例如视频流包括: 携带场景关键信息的 I帧和携带场景辅助信息的 P帧, 对于 I帧, 由于它是没有参考数据的关键场景帧, QoS要求一般是最高的, 误包率 通常在 0.1 %以下; 对于 P帧, 由于它是有参考数据的辅助场景帧, 其 QoS要 求相对于 I帧低的多, 误包率通常在 1 %以下。

步骤 103、 基站根据数据帧类型参数, 从业务流中解析出音频数据帧、 字 幕数据帧、 视频流的 I帧和 P帧等数据帧。
步骤 104、基站根据视频流的 I帧和 P帧各自的 QoS参数, 音频数据帧的
QoS参数、 字幕数据帧的 QoS参数, 对视频流的 I帧和 P帧、 音频数据帧、 字幕数据帧进行资源分配。
步骤 105、 基站以各种类型数据帧被分配的资源发送对应类型的数据帧。 其中, 步骤 101中基站获取视频业务参数具体包括: 基站向视频业务设备 发送携带视频业务类型的业务请求消息;视频业务设备根据视频业务类型,从 预置的不同类型视频业务参数中获取视频业务类型所对应的视频业务参数,其 中, 视频业务设备可以是接入网关、 核心网设备、 或者视频应用服务器, 具体 实现参见下述的第一、 二、三种实现方式。 或者基站从与视频应用服务器约定 的业务参数中获取视频业务参数, 具体参见下述第四种方式。
第一种方式: 在视频业务建立过程中, 视频应用服务器(视频业务服务器 或者视频策略服务器)将预先配置的视频业务参数发送给基站, 具体包括: 步骤 201、 当终端建立视频业务时, 基站向接入网关发送业务请求消息, 该业务请求消息中包括: 视频业务类型。
步骤 202、 接入网关向核心网发送业务请求消息。
步骤 203、 核心网向视频应用服务器发送业务请求消息。
步骤 204、视频应用服务器根据业务请求消息中的视频业务类型获取视频 业务参数, 并向接入网关发送视频业务参数。
在该步骤之前,视频业务服务器或者视频策略服务器统一定义和规划在无 线通信网络上承载的视频业务, 配置不同类型视频业务参数。在接收到携带视 频业务类型的业务请求消息后, 获取该视频业务的参数。
该步骤的实现方式可以是:视频业务服务器或者视频策略服务器直接发送 携带视频业务参数的消息至接入网关; 也可以是:视频业务服务器或者视频策 略服务器将携带视频业务参数的消息发送至核心网, 由核心网发送到接入网 关, 不影响本发明的实现。
上述视频业务参数可以承载在现有的消息中 ,比如承载在连接建立成功消 息中, 也可以通过新增加的消息传输, 都可以实现本发明的目的。
步骤 205、 接入网关向基站发送视频业务参数。
第二种方式: 在视频业务建立过程中,接入网关将预先配置的视频业务参 送给基站。
在这种实现方式中,接入网关预先统一定义和规划在无线通信网络上承载 的视频业务, 配置不同类型视频业务参数, 根据终端所请求的视频业务类型, 将该视频业务参数发送给基站。
该方式的具体实现可以是: 在视频业务建立过程中, 通过新增加的消息传 输视频业务参数; 也可以是: 在视频业务建立过程中, 承载在现有的消息中发 送, 比如重用无线通信网络中已有的 QoS参数传递消息, 不影响本发明的实 现。 例如, 原先在无线通信系统中已存在承载视频业务 QoS参数的消息: QoS 参数传递消息, 为实现本发明的目的,修改该消息的部分字段或者增加部分字 段, 达到传送视频业务参数的目的。 表 1 是以 WiMAX ( Worldwide Interoperability for Microwave Access, 波存取全求互通 ) 系统为例 , 通过修 改接入网关和基站之间的 QoS参数传递消息来承载视频业务参数的列表。 消息字段 消息内容描述
消息类型 无线资源请求
基站信息 目标基站的标识
终端信息 用户终端的标识 业务流标识 具体承载的业务流标识
方向 具体的业务流方向
支持 ARQ标识 是否支持 ARQ功能
支持 HARQ标识 是否支持 HARQ功能
QoS信息 音频数据帧的 QoS参数、字幕数 据帧的 QoS参数, 视频流的 I帧和 P 帧各自的 QoS参数
QoS扩展信息 业务流中所包含的音频数据帧、 字幕数据帧、 视频流中 I帧和 P帧等 数据帧类型参数
分类器规则描述 描述当前业务的分类器规则
表 1
上述表 1的 QoS参数传递消息中增加了 QoS扩展信息,该 QoS扩展信息 包含了业务流中所包含的音频数据帧、 字幕数据帧、视频流中 I帧和 P帧等数 据帧类型参数, 同时修改当前业务流的 QoS信息的内容, 改为包括: 音频数 据帧的 QoS参数、 字幕数据帧的 QoS参数, 视频流的 I帧和 P帧各自的 QoS 参数。
第三种方式: 在视频业务建立过程中,核心网将预先配置的视频业务参数 发送给基站。
在这种实现方式中,核心网预先统一定义和规划在无线通信网络上承载的 视频业务, 配置不同类型视频业务参数。
具体实现可以是: 在视频业务建立过程中,核心网中的鉴权服务器根据终 端所请求的视频业务类型,将自身预先配置的该视频业务的参数发送至接入网 关 , 接入网关发送上述视频业务参数至基站。
其中, 上述核心网中的鉴权服务器发送视频业务参数至接入网关可以是: 在视频业务建立过程中, 核心网新发起的消息, 也可以是: 在视频业务建立过 程中, 承载在现有的消息中发送, 比如重用无线通信网络中已有的 QoS参数 传递消息。 不影响本发明的实现。
第四种实现方式: 基站和视频应用服务器之间约定业务参数,基站从约定 的业务参数中获取该视频业务参数。
这种实现方式中,基站的媒体接入层通过约定了解到基站应用层的视频业 务参数,无需在无线通信网络和视频业务服务器或者视频策略服务器之间传递 任何 QoS参数信息。 上述约定是定义内部的私有协议, 按照该协议实现, 不 需要公开, 也不需要遵循任何公开标准。
其中步骤 104具体的实现包括:
1、 编码分配方式
对于 QoS参数高于预设 QoS阔值的数据帧, 分配调制效率低于或等于第 一阔值的调制编码方式, 从而保证传输的可靠性; 对于 QoS参数低于或等于 预设 QoS 阔值的数据帧, 分配调制效率高于第一阔值的调制编码方式, 争取 更高的资源利用率。 其中, 第一阔值为预定的调制效率, 可以 据视频业务的 不同应用场景改变该第一阔值, 不影响本发明的实现。
下面举例说明编码分配方式: 在 WiMAX系统中, ϋ殳当前用户的无线环 境较好, CINR (载波干扰比) = 15dB, 按照 1 %误包率的调解要求, 第一阔 值设定为 16QAM 3/4。 当基站为用户提供下行视频业务时,如果当前传输的是 视频 I帧, 就选择低于第一阔值的调制编码方式, 比如选择 16QAM 1/2的调 制编码方式; 如果当前传输的是音频数据帧, 就选择正常的调制编码方式 16QAM 3/4; 如果当前传输的是字幕数据帧, 就选择高于第一阔值的调制编码 方式, 比如 64QAM l/2。
2、 发射功率分配方式
对于 QoS参数高于预设 QoS阔值的数据帧, 分配高于第二阔值的发送功 率, 从而保证传输的可靠性; 对于 QoS参数低于或等于预设 QoS阔值的数据 帧, 分配低于或者等于第二阔值的发送功率, 争取更高的资源利用率。 其中, 第二阔值为预定的发送功率,可以根据视频业务的不同应用场景改变该第二阔 值, 不影响本发明的实现。
3、 多天线分配方式
对于 QoS参数高于预设 QoS阔值的数据帧, 分配分集增益高于第三阔值 的分集增益多天线分配方式, 从而保证传输的可靠性; 对于 QoS参数低于或 等于预设 QoS 阔值的数据帧, 分配复用增益高于第四阔值的复用增益多天线 分配方式, 争取更高的资源利用率。 或者, 对于 QoS参数高于预设 QoS阔值 的数据帧, 分配编码增益较高的多天线分配方式, 从而保证传输的可靠性。 其 中, 第三阔值为预定的分集增益,可以^ ^据视频业务的不同应用场景改变该第 三阔值, 第四阔值为预定的复用增益,可以^ ^据视频业务的不同应用场景改变 该第四阔值, 不影响本发明的实现。
4、 重传方式
对于 QoS参数高于预设 QoS阔值的数据帧, 分配编码增益高于第五阔值 的重传方式, 从而保证传输的可靠性; 对于 QoS参数低于或等于预设 QoS阔 值的数据帧,分配编码增益低于或者等于第五阔值的重传方式,争取更高的资 源利用率。
资源分配方式包括但不限于上述四种方式,可以才 据视频业务的不同应用 场景而不同。

该步骤中获取视频业务参数的方式与实施例一相同,请参阅实施例一的相 关描述。
步骤 302、 基站从应用服务器接收该视频业务的各业务流。
步骤 303、 基站根据表示视频流包含 I帧和 P帧的数据帧类型参数, 从视 频流中解析出 I帧和 P帧。
步骤 304、基站根据音频流、 字幕流各自的 QoS参数, 对音频流和字幕流 进行资源分配;根据视频流中 I帧和 P帧的 QoS参数,对 I帧和 P帧进行资源 分配。
该步骤的实现方式与实施例一相同, 请参阅实施例一的相关描述。
步骤 305、 基站以音频流、 字幕流被分配的资源发送音频流、 字幕流, 以 视频流中 I帧和 P帧各自被分配的资源, 发送视频流中的 I帧和 P帧。
上述本发明实施例二是以视频流为例说明在多个连接来传递整个视频业 务时, 其中一个业务流中可以有不同类型的数据帧, 比如视频流, 但本发明实 施例二不仅限于视频流,其他含有不同类型数据帧的数据流也适用于本发明实 施例二。
本发明实施例二也可以适用于仅使用一个数据连接来传输整个视频业务, 且该视频业务仅包括一个数据流的情况,该数据流包括不同类型的数据帧, 例 如视频 1U„
