104、 基站将打包信息进行物理层接口适配得到传输信息;
本实施例中,基站对数字信息进行打包得到打包信息之后,再根据物理层 对该打包信息进行接口适配, 得到传输信息。
本实施例中具体的适配可以为:基站将打包信息进行物理层接口适配得到 E1接口的传输信息, 或快速以太网 ( FE , Fast Ethernet )接口的传输信息, 或 非对称数字用户线路( ADSL, Asymmetric Digital Subscriber Line )接口的传 输信息, 或无源光纤网络(PON, Passive Optical Network )接口的传输信息。
需要说明的是, 本实施例中仅以 E1接口, FE接口, ADSL接口以及 PON 接口为例进行说明, 可以理解的是, 在实际应用中, 具体的物理层接口还可以 为其他类型的接口, 此处不做限定。
105、 基站将传输信息发送至网络的集中处理设备, 以便于集中处理设备 对传输信息进行网络业务协议处理。
本实施例中,基站将打包信息进行物理层接口适配得到传输信息之后, 即 直接将该传输信息发送至网络的第一集中处理设备进行网络业务协议处理,而 基站本身只会执行最简单、 最基本的与报文组包处理和接口适配。
本实施例中,第一集中处理设备可以与多个基站之间进行通讯,并对各基 站发送的传输信息进行网络业务协议处理,即各基站内部均可不执行网络业务 协议处理的过程, 而由第一集中处理设备集中实现。
本实施例中的第一集中处理设备可以为宽带接入服务器 (BRAS , Broadband Remote Access Server ), 城域以太网网元, 光纤线路终端 ( OLT,
Optical Line Terminal ), 多业务传输平台 (MSTP, Multiple services transition platform )或宽带接入设备、综合接入设备、数字用户线接入复用器( DSLAM, Digital Subscriber Line Access Multiplexer ), 或综合业务接入设备 ( MS AN, Multiservice Access Node )等设备, 需要说明的是, 第一集中处理设备根据基 站发送的传输信息执行网络业务协议处理,具体可以由该第一集中处理设备中 的原有模块实现,也可以在该第一集中处理设备上增加一块单板, 专门用于执 行网络业务协议处理。
需要说明的是, 本实施例中, 网络业务协议处理包括对数据链路层, 网络 层, 传输层, 会话层, 表示层以及应用层的协议进行处理, 即除物理层之外的 其他六个层次中的协议的处理, 具体的处理包括接口协议适配, 数据封装, 解 封装, 数据传输等, 或者还可以有其他的处理类型, 具体的网络业务协议处理 的过程为本领域技术人员的公知常识, 此处不作限定。
现有技术中, 基站中的网络业务协议处理的过程可以通过软件编程实现, 或者通过硬件编程实现(即在基站中增加一块专门用于执行网络业务协议处理 的单板), 本实施例中, 当由该第一集中处理设备执行网絡业务协议处理时, 同样也可以采用软件编程或硬件编程的实现方式。
若第一集中处理设备采用硬件编程的实现方式,则同样可以在第一集中处 理设备中增减一块专门用于执行网络业务协议处理的单板,该单板的具体实现 方式与现有技术中在基站中使用的专门用于执行网络业务协议处理的单板的 实现方式类似, 属于本领域技术人员的公知常识;

Gateway General Packet Radio Service Supporting Node ) 集成实现。 上面仅描述了本实施例中基站的单向数据传输流程, 需要说明的是,在实 际应用中,基站通常会进行双向的数据传输, 即从移动终端到网络侧的数据传 输以及从网络侧到移动终端的数据传输, 这两个传输过程可以看作是逆过程, 前面说明了从移动终端到网络侧的数据传输,则从网络侧到移动终端的数据传 输过程可以为:
( 1 )基站从网络的第一集中处理设备接收经过网络业务协议处理之后的 传输信息;
当网络侧需要向移动终端发送数据时,会首先将需要发送的数据发送至第 一集中处理设备。
第一集中处理设备接收到数据之后可以进行网络业务协议处理,并将处理 后的传输信息发送至基站。
( 2 )基站对所述传输信息进行解封包得到数字信息;
( 3 )基站对所述数字信息进行基带处理以及中射频处理得到信号;

上述对基站进行功能缩减之后, 具体的基站结构如图 2所示, 其中, 基站 中的网络业务协议处理模块被精简,从而能够降低基站性能需求, 減小基站体 积, 优化网络结构。
但需要说明的是, 为增加基站与现网的兼容性, 可以在基站中仍旧保留完 整的网络业务协议处理模块,在实际应用中, 当网络能够支持基站的功能精简 时 ,则基站不启用该网络业务协议处理模块,若网络不能支持基站的功能精简 , 则基站仍可使用该网络业务协议处理模块进行网络业务协议处理。
请参阅图 3 , 本发明实施例中数据通讯方法另一实施例包括:
301、 第一集中处理设备接收基站发送的传输信息;
本实施例中, 第一集中处理设备可以从基站接收到传输信息, 该传输信息 按照前述实施例中描述的流程, 由基站进行物理层接口适配得到, 具体的物理 层接口可以为 E1接口, FE接口, XDSL接口或者 ΡΟΝ接口, 或者还可以为 其他类型的物理层接口, 此处不做限定。
302、 第一集中处理设备对传输信息进行网络业务协议处理;
第一集中处理设备接收到基站发送的传输信息之后,即可对该传输信息进 行网络业务协议处理, 具体可以包括: 对数据链路层, 网络层, 传输层, 会话 层, 表示层以及应用层的协议进行处理, 包括协议的转换, 适配以及封装等。
本实施例中,第一集中处理设备执行网络业务协议处理的过程与现有技术 中基站执行的网络业务协议处理的过程类似, 此处不再赘述。
303、 第一集中处理设备将经过网络业务协议处理之后的信息发送至网络 侧。
第一集中处理设备对传输信息完成网络业务协议处理之后,即可将处理之 后的信息发送至网络侧。
本实施例中的第一集中处理设备可以为 BRAS, 城域以太网网元, OLT, 或 MSTP, 宽带接入设备、 数字用户线接入复用器, 或综合业务接入设备等, 需要说明的是, 第一集中处理设备根据基站发送的信息执行网络业务协议处 理, 具体可以由该第一集中处理设备中的原有单板实现, 即可以在该第一集中 处理设备中原先执行其他的功能的单板上增加网络业务协议处理的功能,也可 以在该第一集中处理设备上增加一块单板, 专门用于执行网络业务协议处理, 具体的实现方式与前述图 2所示的实施例中步骤 105描述的处理方式相同,此 处不再赘述。
本实施例中的第一集中处理设备并不限于上面提到的网元,在实际应用中 还可以是其他类型的网元, 具体此处不做限定, 此外, 本实施例中的第一集中 处理设备在实际应用中还可以与 GGSN集成实现。
上面仅描述了本实施例中第一集中处理设备的单向数据传输流程,需要说
明的是, 在实际应用中, 第一集中处理设备通常会进行双向的数据传输, 即从 基站到网络侧的数据传输以及从网络侧到基站的数据传输,这两个传输过程可 以看作是逆过程, 前面说明了从基站到网络侧的数据传输, 则从网络侧到基站 的数据传输过程可以为:
( 1 ) 第一集中处理设备接收网络侧发送的信息;
当网络侧需要向基站发送数据时,会首先将需要发送的数据发送至网络的 第一集中处理设备。
( 2 ) 第一集中处理设备对所述信息进行网络业务协议处理;
第一集中处理设备接收到数据之后可以进行网络业务协议处理,具体的网 络业务协议处理可以为对数据链路层, 网络层, 传输层, 会话层, 表示层以及 应用层的协议进行处理, 包括协议的转换, 适配以及封装等。
( 3 ) 第一集中处理设备将经过网络业务协议处理之后的传输信息发送至 基站。
本发明实施例中, 第一集中处理设备可以代替基站完成网络业务协议处 理, 因此, 本发明实施例中的基站可以只负责执行中射频、 基带处理以及最基 本的接口信息等基础功能,而对于网络业务协议处理功能则主要转移到网络的 集中处理设备进行处理,所以减轻了基站的负担,从而能够降低基站性能需求, 减小基站体积, 优化网络结构。
需要说明的是, 上述各实施例中, 原先由基站执行的网络业务协议处理功 能转由第一集中处理设备进行执行, 在实际应用中, 为进一步简化网元, 优化 网络结构, 本实施例中还可以将无线网络控制器 (RNC , Radio Network Controller )的功能同样转移到网络的第二集中处理设备上执行, 以充分利用集 中处理设备的处理能力, 本实施例中, RNC 的主要功能为: 对基站与核心网 之间的业务适配, 业务隔离以及业务转发进行控制。 可以将 RNC的全部或部 分功能转移到第二集中处理设备进行执行, 此外, 本实施例中, RNC 的功能 以及基站的网络业务协议处理功能可以转移到网络的同一个集中处理设备进 行执行(即第一集中处理设备与第二集中处理设备为同一个设备), 例如全部 转移至 BRAS, 城域以太网网元, OLT或 MSTP执行, 同时, RNC的功能以 及基站的网络业务协议处理功能也可以分别转移到网络的不同的集中处理设
备进行执行(即第一集中处理设备与第二集中处理设备为不同的设备), 例如 将 RNC的功能转移到 BRAS上执行, 则基站的网络业务协议处理功能可以转 移到城域以太网网元, OLT或 MSTP或宽带接入设备、 DSLAM/MSAN等执 行。
为便于理解, 下面以 RNC的功能以及基站的网络业务协议处理功能转移 到网络的同一个集中处理设备进行执行为例进行说明, 请参阅图 4, 图 4所示 的是集成了基站的网络业务协议处理功能以及 RNC的全部功能的集中处理设 备。
需要说明的是, 本实施例中, 集中处理设备集成了基站的网络业务协议处 理功能以及 RNC的全部功能后, 在网络中可以无需 RNC, 即原先由 RNC执 行的功能全部转移到由集中处理设备进行处理, 现有网络的 RNC主要执行基 站与核心网之间的业务适配, 业务隔离以及业务转发等功能, 从数据传输层面 来看, 主要包括用户面以及控制面的数据处理过程, 本实施例中, 用户面以及 控制面的数据处理均转移到集中处理设备进行, 且具体的处理过程与 RNC执 行的处理过程类似, 此处不再赘述。
图 5所示的是集成基站的网絡业务协议处理功能以及 RNC的控制面数据 处理功能的集中处理设备。
需要说明的是, 本实施例中, 集中处理设备集成了基站的网络业务协议处 理功能以及 RNC的控制面数据处理功能后,在网络中仍需要 RNC执行用户面 的数据处理, 本实施例中, 集中处理设备执行控制面数据处理的过程与 RNC 执行控制面数据处理的过程类似, 此处不再赘述。
可以理解的是,集中处理设备中同样可以仅集成基站的网络业务协议处理 功能, 而不集成 RNC的任何功能。
上面提供了多种集成的方案,在实际应用中, 可以根据具体需要选取不同 的方案。
现有技术的方案中, C 和基站的各自处理一部分业务, 两者接口互通 共同完成全部业务。 RNC相对来说是独立于网络的, 所以无法获取到网络的 相关资源信息, 从而对网络的资源不能实时掌控和分配, 比如无法实现 RNC 到基站的层次化服务盾量( HQoS, Hierarchical Quality of Service )分配, 因
此不能有效保证基站对网络资源的有效利用, 而本实施例中, 可以将 RNC的 全部功能转移到网络的集中处理设备 (既可是第一集中处理设备, 也可以是第 二集中 出设备 )执行, 而集中处理设备在实际应用中可以为 BRAS, 城域以 太网网元, OLT, 或 MSTP, 宽带接入设备、 数字用户线接入复用器, 或综合 业务接入设备等, 因此能够获取到网络中的相关资源信息, 因此能够对网络的 资源进行实时掌控和分配, 从而保证基站对网络资源的有效利用。

三、基站变得更简单, 有助于进一步缩小基站的体积, 有利于以后基站与 无线远端设备 ( RRU, Radio Remote Unit ) 的合并;
四、 现有技术的方案中, RNC 和基站的各自处理一部分业务, 两者接口 互通共同完成全部业务。 RNC相对来说是独立于网络的, 对网络的资源不能 实时掌控和分配, 比如无法实现 RNC到基站的 HQoS分配, 因此不能有效保 证基站对网络资源的有效利用, 而本实施例中 , 可以将 RNC的全部功能转移 到网络的第二集中处理设备执行, 因此能够对网络的资源进行实时掌控和分 配, 从而保证基站对网络资源的有效利用;
五、 集中处理单元的单板面积远比基站大, 处理能力也比基站高, 并且能 以资源池方式工作, 可以支持更为强大的处理能力, 因此可以减少基站因为业 务升级,处理能力不足而更换升级单板的概率,保护用户投资,降低维护费用; 六、本实施例由集中处理设备执行网络业务协议处理之后, 所以当网络业 务升级而需调整业务接口时, 只需要调整集中处理设备的业务接口即可, 无需 调整基站的接口,从而可以避免基站和网络设备之间业务接口复杂, 开销大的 问题;
七、 随着技术进步, 芯片处理能力和容量越来越大, 在独立的集中业务处
理单元上进行业务处理, 可以有效的提高资源使用的效率高得多; 八、在基站上进行业务处理, 如果未来需求变化而不能满足, 有可能要更 换板卡。 则会导致基站的板卡大量更换从而增加成本。 尤其是增加运维成本, 因为更换基站板卡, 由于基站的分布地点, 施工的工作量非常大。 而集中业务 处理单元往往只需要增加一块业务处理板即可提升业务能力, 而无需频繁更 换,其数量远远小于基站,并且只需要在中心机房就能完成,施工量大大降低, 因此能够有效降低成本。 是可以通过程序来指令相关的硬件完成,所述的程序可以存储于一种计算机可 读存储介质中, 上述提到的存储介质可以是只读存储器, 磁盘或光盘等。
以上对本发明所提供的一种数据通讯方法及数据通讯系统以及相关设备 进行了详细介绍,对于本领域的一般技术人员,依据本发明实施例的思想, 在 具体实施方式及应用范围上均会有改变之处, 综上所述,本说明书内容不应理 解为对本发明的限制。
