Abstract

本发明涉及移动通信领域，公开了一种移动通信网络中Iub接口数据传输方法及其系统，使得Iub接口的传输效率得以提高。本发明中，使用SDTP协议进行Iub接口的数据传输。对于每一条FP层的连接，底层需要提供两个链路，一条是当FP帧的长度小于M字节时，采用IP地址和UDP端号映射到SDTP节点号和MUX-AL端口号，另一条是当FP帧的长度大于等于M字节时，直接利用IP地址和UDP打包，采用D-AL承载。

Description

移动通信网络中Iub接口数据传输方法及其系统
技术领域
本发明涉及移动通信领域，特别涉及移动通信网络中Iub接口数据传输技术。
背景技术
宽带码分多址(Wideband Code Division Multiple Access，简称“WCDMA”)是第三代移动通信(the 3rd Generation，简称“3G”)三种主流标准的一种，它继承了现有的全球移动通信系统(Global Systems forMobile communications，简称“GSM”)标准化程度高和开放性好的特点，与GSM网络有良好的兼容性和互操作性，是未来移动通信的发展趋势之一。
WCDMA系统中，无线接入网(Radio Access Network，简称“RAN”)包含无线网络控制器(Radio Network Controller，简称“RNC”)和作为基站的B节点(Node B)。其中，各个Node B用于接收所辖范围内的用户设备(User Equipment，简称“UE”)信号，经过处理后将其通过传输通道汇总到RNC；RNC用于集中处理Node B传输过来的信息，并将处理过的信息通过Node B发送给UE。
为了节约建网时RNC的成本，一个RNC通常需要提供大面积覆盖，它连接并控制多个Node B，与之连接的Node B可以距离RNC很远，可达上百公里，而且Node B彼此间的距离也较远。Node B和RNC之间通过Iub接口连接。
Iub接口协议有异步传输模式(Asynchronous Transfer Mode，简称“ATM”)和网间互联协议(Internet Protocol，简称“IP”)两种。由于宽带码分多址(Wideband Code Division Multiple Access，简称“WCDMA”)的ATM网络和IP网络很发达，而Iub接口的传输主要是利用ATM网络或者IP网络，因此，采用ATM和IP可以充分利用现有的低成本高带宽具有统计复用的ATM网络或IP网络，以降低系统传输费用。
当前Iub接口采用的最主要的传输仍然是端到端的一次群(E1/T1)传输模式。其中，E1是欧洲的脉冲编码调制多路复用系统数字体系一次群(或称鉴群)的带宽速率标准，它包含32个64千比特每秒(kbit/s)的信道，一次群的带宽速率为2.048兆比特每秒(Mbit/s)。T1是北美、日本的脉冲编码调制(Pulsed Code Modulation，简称“PCM”)多路复用系统数字体系一次群(或称基群)的带宽速率标准，它包含24个电话信道，其带宽速率为1.544Mbit/s，其中每个信道为64kbit/s。
目前，当Iub接口采用IP方式传输时，采用流控制传输协议(StreamControl Transmission Protocol，简称“SCTP”)承载控制平面数据，具体协议为：NodeB应用部分(NodeB Application Part，简称“NBAP”)/STCP/网际协议(Internet Protocol，简称“IP”)/多协议/高级数据链路控制(High-LevelData Link Control，简称“HDLC”)/E1；采用用户数据报协议(User DatagramProtocol，简称“UDP”)承载无线用户平面数据，具体协议为：帧协议(FrameProtocol，简称“FP”)/UDP/IP/多协议/HDLC/E1；采用传输控制协议(Transmission Control Protocol，简称“TCP”)承载操作维护数据，具体协议为：操作维护/TCP/IP/多协议/HDLC/E1。
在实际应用中，存在以下问题：当Iub接口在端到端采用E1/T1传输时，传输效率非常低下。
造成这种情况的主要原因在于，当初开发ATM和IP技术时，就认为承载网的带宽足够大，开发时关注的主要是转发速率，而不是传输效率，所以ATM和IP的传输效率都比较低。然而，当Node B与RNC之间采用E1/T1端到端地传输大带宽的业务数据时，由于E1/T1的带宽不大，每比特的传输成本比较高，所以传大带宽的NODEB与RNC之间的数据业务就不经济了。而对于运营商来说，这种传输方式不利用于减少WCDMA网络内用于传输的E1/T1的数目，也就无法降低建设成本和维护成本，无法保障运营商的赢利能力。

其中，如果所述源节点发送经直接适配层适配的数据帧，则使用目标节点的所述节点号在所述IP层的下层对该数据帧进行封装并发送，所述目标节点根据收到的数据帧的节点号找到相应的IP地址和用户数据报协议端口号，完成该数据帧的接收；

此外在所述方法中，如果发送给用户设备的帧协议数据帧小于指定长度，则该帧协议数据帧由所述复用适配层进行适配；
如果发送给用户设备的帧协议数据帧大于或等于所述指定长度，则该帧协议数据帧由所述直接适配层进行适配。
此外在所述方法中，所述数据帧包含用于传输操作维护数据的帧和/或用于传输基站节点应用部分数据的帧；
所述用于传输操作维护数据的帧和所述用于传输基站节点应用部分数据的帧由所述直接适配层进行适配。
此外在所述方法中，所述IP层的下层为简单数据传输协议层。
此外在所述方法中，还包含以下步骤：
所述目标节点在收到所述数据帧时，先判断该数据帧的节点号是否为本节点的节点号，如果是，则再根据收到的数据帧的节点号或节点号和复用微帧端口号找到相应的IP地址和用户数据报协议端口号。
此外在所述方法中，所述源节点为无线网络控制器，所述目标节点为基站节点；或者，
所述源节点为基站节点，所述目标节点为无线网络控制器。
此外在所述方法中，所述无线网络控制器对应于每一个所述基站节点设置有不同的节点号。
本发明还提供了一种移动通信网络中Iub接口数据传输系统，包含源节点和目标节点，所述源节点内包含：封装模块，用于根据预先在IP层的下层设置的对应于目标节点的IP地址和用户数据报协议端口号的节点号，或节点号和复用微帧端口号，在所述IP层的下层对数据帧进行封装；以及发送模块，用于将所述封装模块封装后的数据帧发送给目标节点；
所述目标节点内包含查找接收模块，用于根据收到的数据帧的节点号或节点号和复用微帧端口号找到相应的IP地址和用户数据报协议端口号，完成该数据帧的接收。
其中，所述源节点的封装模块使用目标节点的所述节点号在所述IP层的下层对经直接适配层适配的数据帧进行封装，所述目标节点的查找接收模块根据收到的数据帧的节点号找到相应的IP地址和用户数据报协议端口号，完成该数据帧的接收；
所述源节点的封装模块使用目标节点的所述节点号和复用微帧端口号在所述IP层的下层对经复用适配层适配的数据帧进行封装，所述目标节点的查找接收模块根据收到的数据帧的节点号和复用微帧端口号找到相应的IP地址和用户数据报协议端口号，完成该数据帧的接收。

通过比较可以发现，本发明的技术方案与现有技术的主要区别在于，预先在IP层的下层设置对应于本节点的IP地址和UDP端口号的节点号，或节点号和复用微帧端口号。如果源节点发送经直接适配层适配的数据帧，则使用目标节点的节点号在IP层的下层对该数据帧进行封装并发送，目标节点根据收到的数据帧的节点号找到相应的IP地址和用户数据报协议端口号，完成该数据帧的接收；如果源节点发送经复用适配层适配的数据帧，则使用目标节点的节点号和复用微帧端口号在IP层的下层对该数据帧进行封装并发送，目标节点根据收到的数据帧的节点号和复用微帧端口号找到相应的IP地址和用户数据报协议端口号，完成该数据帧的接收。解决了Iub接口的上层数据在简单数据传输协议(Simple Data Transport Protocol，简称“SDTP”)中承载的问题，使得信息数据能以SDTP的方式进行承载与发送，从而提高了Iub接口的传输效率。由于传输效率的提高将直接降低投资成本和运营成本，因此可提高运营商的赢利能力。
由于用于传输操作维护数据的帧为控制信息，与用于传输基站节点应用部分数据的帧都属于同一连接的信息，因此，如果发送的数据帧为用于传输操作维护数据的帧或用于传输基站节点应用部分数据的帧，则将该数据帧由直接适配层进行适配，进一步提高了Iub接口的传输效率。
由于帧协议数据帧可能属于多个不同的连接，因此根据该帧协议数据帧的大小决定由直接适配层或复用适配层进行适配，进一步充分利用了高传输效率的SDTP协议，大大降低了传输成本。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述。
本发明的核心在于，如果源节点发送经直接适配层(D-AL)适配的数据帧，则将目标节点的IP地址和UDP端口号映射为目标节点的节点号，利用该节点号在IP层的下层对该数据帧进行封装并发送，目标节点根据收到的数据帧的节点号找到相应的IP地址和UDP端口号，完成该数据帧的接收。如果源节点发送经复用适配层(MUX-AL)适配的数据帧，则将目标节点的IP地址和UDP端口号映射为目标节点的节点号和复用微帧端口号，利用该节点号和复用微帧端口号在IP层的下层对该数据帧进行封装并发送，目标节点根据收到的数据帧的节点号和复用微帧端口号找到相应的IP地址和用户数据报协议端口号，完成该数据帧的接收。
具体地说，由于WCDMA Iub接口采用SDTP传输的承载方式如表1所示，NBAP由直接适配层直接承载，由于操作维护(OM)数据一般采用TCP/IP协议承载，所以采用OM/TCP/IP/D-AL的方式承载OM数据。对于FP帧，它有两种承载方式，第一种承载方式是FP直接使用复用适配层承载，另外一种是FP/UDP/IP/D-AL承载方式，并进行IP包分片功能。根据FP的长度决定FP具体采用的承载方式，如当FP的长度小于或等于预定长度M时，采用第一种承载方式，当FP的长度大于M时，采用第二种承载方式，M的长度单位是字节。

             表1
由于通过支持IP的NBAP层协商出的作为FP帧的一个单向连接包含源IP地址、源UDP端口号、目的IP地址、和目的UDP端口号。也就是说，当该单向连接为上行连接时，源IP地址和源UDP端口号为NodeB的IP地址和NodeB的UDP端口号，目标IP地址和目标UDP端口号为RNC的IP地址和RNC的UDP端口号；当该单向连接为下行连接时，源IP地址和源UDP端口号为RNC的IP地址和RNC的UDP端口号，目标IP地址和目标UDP端口号为NodeB的IP地址和NodeB的UDP端口号。
在本发明方案中，根据发送的数据帧是经直接适配层适配的数据帧还是经复用适配层适配的数据帧，来决定将目标IP地址和目标UDP端口号映射为目标节点的节点号，还是目标节点的节点号和复用微帧端口号。如果映射为目标节点的节点号，则源节点在IP层的下层利用目标节点的节点号对该数据帧进行封装并发送，目标节点根据收到的数据帧的节点号找到相应的IP地址和UDP端口号，完成该数据帧的接收。如果映射为目标节点的节点号和复用微帧端口号，则源节点在IP层的下层利用目标节点的节点号和复用微帧端口号对该数据帧进行封装并发送，目标节点根据收到的数据帧的节点号和复用微帧端口号找到相应的IP地址和UDP端口号，完成该数据帧的接收。
需要说明的是，对于RNC而言，同一个物理端口可以带几个NodeB，一个节点号所支持的MUX-AL端口号可能不够用，所以要求RNC同一个物理端口可支持多个节点号。
以上对本发明的核心做了介绍，下面根据该原理，对本发明的第一实施方式进行详细阐述。本实施方式涉及移动通信网络中Iub接口数据传输方法，在本实施方式中，以SDTP的方式传输WCDMA Iub接口的操作维护数据，即首先由WCDMA Iub接口通过SDTP协议建立操作维护传输通道，然后通过操作维护和SDTP协议建立NBAP传输通道，最后通过NBAP、操作维护和SDTP协议建立FP帧传输通道。
操作维护数据的发送流程如图1所示。需要说明的是，在进入步骤101之前，APP(应用)层需要配置用于操作维护数据传输的源节点号和目的节点号。源节点号对应于源节点的IP地址和UDP端口号，目的节点号对应于目的节点的IP地址和UDP端口号。
由于RNC的同一个物理端口可以带几个NodeB，一个节点号所支持的MUX-AL端口号可能不够用，因此为每个NodeB配置一个RNC的源节点号，不同NodeB所对应的RNC源节点号不同。
在步骤101中，APP层将待传送的操作维护数据实现OM/TCP/IP协议栈，并把IP包发给D-AL层，把目的节点号发给SDTP层。
接着，进入步骤102，D-AL层进行D-AL帧封装，并将封装后的数据帧发给SDTP层。由于用于传输操作维护数据的帧为控制信息，属于同一连接的信息，因此，将该数据帧由直接适配层进行适配，可进一步提高了Iub接口的传输效率。
接着，进入步骤103，SDTP层进行SDTP帧封装，并标识APP的协议类型为IP，并设置目的节点号，也就是说，利用目标节点的节点号在SDTP层对该数据帧进行封装。
接着，进入步骤104，源节点的类高级数据链路控制(High-Level DataLink Control，简称“HDLC”)层以下各层对经SDTP层封装后的数据帧进行处理后发送。
操作维护数据的接收流程如图2所示。同样地，在进入步骤201之前，APP层需要配置用于操作维护数据传输的源节点号和目的节点号。源节点号对应于源节点的IP地址和UDP端口号，目的节点号对应于目的节点的IP地址和UDP端口号。由于RNC的同一个物理端口可以带几个NodeB，一个节点号所支持的MUX-AL端口号可能不够用，因此为每个NodeB配置一个RNC的源节点号，不同NodeB所对应的RNC源节点号不同。
在步骤201中，本节点的类HDLC以下各层接收来自线路上的数据，并向上传输到SDTP层。
接着，进入步骤202，判断收到的SDTP帧的目的节点号是否为本节点的节点号。如果是本节点的节点号，则说明本节点为目标节点，进入步骤203，否则，说明本节点并非目标节点，进入步骤207。
在步骤203中，SDTP层进行拆帧，并取出协议标识和目的节点号。
接着，进入步骤204，根据取出的协议标识判断协议类型是否为IP，如果是，则进入步骤205，否则，进入步骤207。
在步骤205中，由D-AL层进行拆帧，并向APP层传送IP包。
接着，进入步骤206，APP层接收来自D-AL层的IP包数据和SDTP层的目的节点号，APP层通过OM/TCP/IP协议栈解决OM数据，完成接收过程。
如果在步骤202中判定收到的SDTP帧的目的节点号并非本节点的节点号，或者，在步骤204中根据取出的协议标识判定协议类型不是IP，则进入步骤207，对收到的数据进行其它处理，完成接收过程。
由此可见，通过将目标节点的IP地址和UDP端口号在SDTP层映射为目标节点的节点号，解决了Iub接口的上层数据在SDTP中承载的问题，使得信息数据能以SDTP的方式进行承载与发送，从而提高了Iub接口的传输效率。由于传输效率的提高将直接降低投资成本和运营成本，因此可提高运营商的赢利能力。
本发明的第二实施方式涉及移动通信网络中Iub接口数据传输方法，在本实施方式中，以SDTP的方式传输WCDMA Iub接口的NBAP数据。本实施方式与第一实施方式大致相同，其区别仅在于，在第一实施方式中，Iub接口承载的是操作维护数据，而在本实施方式中，Iub接口承载的是NBAP数据。
NBAP数据的发送流程如图3所示。需要说明的是，在进入步骤301之前，APP层需要配置用于NBAP数据传输的源节点号和目的节点号。源节点号对应于源节点的IP地址和UDP端口号，目的节点号对应于目的节点的IP地址和UDP端口号。
在步骤301中，APP层将待传送的NBAP数据实现OM/TCP/IP协议栈，并把IP包发给D-AL层，把目的节点号发给SDTP层。
步骤302至步骤304分别与步骤102至步骤104完全相同，在此不再赘述。
NBAP数据的接收流程如图4所示。同样地，在进入步骤401之前，APP层需要配置用于NBAP数据传输的源节点号和目的节点号。源节点号对应于源节点的IP地址和UDP端口号，目的节点号对应于目的节点的IP地址和UDP端口号。
步骤401至步骤403分别与步骤201至步骤203完全相同，在此不再赘述。
在步骤404中，根据取出的协议标识判断协议类型是否为NBAP，如果是，则进入步骤405，否则，进入步骤407。
接着，进入步骤405，由D-AL层进行拆帧，并向APP层传送NBAP数据。
接着，进入步骤406，APP层接收来自D-AL层的NBAP数据和SDTP层的目的节点号，完成接收过程。
如果在步骤402中判定收到的SDTP帧的目的节点号并非本节点的节点号，或者，在步骤404中根据取出的协议标识判定协议类型不是NBAP，则进入步骤407，对收到的数据进行其它处理，完成接收过程。
不难发现，本实施方式同样可以解决Iub接口的上层数据在SDTP中承载的问题，使得信息数据能以SDTP的方式进行承载与发送，从而提高了Iub接口的传输效率。由于传输效率的提高将直接降低投资成本和运营成本，因此可提高运营商的赢利能力。而且，由于用于传输NBAP数据的帧为控制信息，属于同一连接的信息，因此，将该数据帧由直接适配层进行适配，可进一步提高了Iub接口的传输效率。
本发明的第三实施方式涉及移动通信网络中Iub接口数据传输方法，在本实施方式中，以SDTP的方式传输WCDMA Iub接口的FP帧数据。
在本实施方式中，在发送FP帧数据之前，首先需要建立源节点和目标节点之间的连接，也就是NodeB与RNC之间的连接。
具体地说，首先，通过OM协商，APP层需要配置用于FP帧数据传输的源节点号和目的节点号。源节点号对应于源节点的IP地址和UDP端口号，目的节点号对应于目的节点的IP地址和UDP端口号。由于RNC的同一个物理端口可以带几个NodeB，一个节点号所支持的MUX-AL端口号可能不够用，因此为每个NodeB配置一个RNC的源节点号，不同NodeB所对应的RNC源节点号不同。
其次，源节点和目标节点在APP层完成NBAP的Iub IP传输协商，协商IP传输的IP地址和UDP端口号。
最后，由源节点和目标节点的APP层完成IP地址、UDP端口号与节点号和复用微帧端口号的映射，映射关系如下：
下行连接：(IPRNC，UDPRNC，IPNodeB，UDPNodeB)->(NodeNodeB，PortNodeB)
上行连接：(IPNodeB，UDPNodeB，IPRNC，UDPRNC)->(NodeRNC，PortRNC)
也就是说，对于下行连接，将RNC的IP地址、RNC的UDP端口号、NodeB的IP地址和NodeB的UDP端口号映射为NodeB的节点号和NodeB的复用微帧端口号；对于上行连接，将NodeB的IP地址、NodeB的UDP端口号、RNC的IP地址和RNC的UDP端口号映射为RNC的节点号和RNC的复用微帧端口号。需要说明的是，RNC和NodeB都要同时维护上下行连接关系。
在完成NodeB与RNC之间的连接后，方可发送FP帧数据，FP帧数据的发送流程如图5所示。
在步骤501中，APP层接收上层FP帧数据，并把目的端口号，即复用微帧端口号发给MUX-AL层，把目的节点号发给SDTP层，以便当该FP帧需经MUX-AL层适配时，MUX-AL层能利用目的端口号对净荷进行MUX-AL帧封装。
接着，进入步骤502，判断FP帧长度是否小于预定长度M，如果不是，则说明无法对该数据帧进行复用，进入步骤503，否则，说明可对该数据帧进行复用，进入步骤505。
在步骤503中，APP层将待传送的FP数据帧实现FP/UDP/IP协议栈，并在完成IP包分片后下发给D-AL层。
在步骤504中，由D-AL层进行D-AL帧封装，并将封装后的数据帧发给SDTP层。
如果在步骤502中判定FP帧长度小于预定长度M，也就是说可对该数据帧进行复用，进入步骤505，APP层下发FP帧给MUX-AL层，MUX-AL层利用复用微帧端口号对净荷进行MUX-AL帧封装，以区分发送给同一节点的不同用户的数据，并将经MUX-AL层封装后的数据帧发给SDTP层。
由于FP数据帧可能属于多个不同的连接，因此根据该FP数据帧的大小决定由直接适配层或复用适配层进行适配，进一步充分利用了高传输效率的SDTP协议，大大降低了传输成本。
接着，进入步骤506，SDTP层利用目的节点号对经适配层封装后的数据帧进行SDTP帧封装，并标识APP的协议类型为WCDMA FP。
接着，进入步骤507，源节点的类HDLC层以下各层对经SDTP层封装后的数据帧进行处理后发送。
由于在本实施方式中，源节点可能将FP帧复用后进行发送，因此，需要通过目标的节点号区分该数据帧所属的节点，并且，需要通过复用微帧端口号进一步区分该数据帧所属的该节点的不同用户。
在接收FP帧数据之前，同样需要先NodeB与RNC之间的连接，其连接的建立方式与上述方式相同，在此不再赘述。
接收FP帧数据的流程如图6所示，在步骤601中，类HDLC层以下各层接收来自线路上的数据，并向上传输到SDTP层，本步骤与步骤201完全相同。
接着，进入步骤602，判断收到的SDTP帧的目的节点号是否为本节点的节点号。如果是本节点的节点号，则说明本节点为目标节点，进入步骤603，否则，说明本节点并非目标节点，进入步骤605，对收到的数据进行其它处理，完成接收过程。
在步骤603中，SDTP层进行SDTP帧拆帧，取出APP的协议类型、复用标识和节点号。
接着，进入步骤604，判断APP协议类型是否为WCDMA FP，如果不是，则进入步骤605，对收到的数据进行其它处理，完成接收过程，如果APP协议类型是WCDMA FP，则进入步骤606。
在步骤606中，根据复用标识的值判断该数据帧是否为复用的数据帧。如果判定该数据帧是复用的数据帧，则进入步骤609，否则，进入步骤607。
在步骤607中，由D-AL层进行拆帧，并将数据送入APP层。
接着，进入步骤608，在APP层完成IP包分片重组功能，从UDP/IP协议栈中取出FP帧，以及IP地址和UDP端口号，完成接收过程。
如果在步骤606中判定该数据帧是复用的数据帧，则进入步骤609，在MUX-AL层进行MUX-AL拆帧，MUX-AL层将MUX-AL的净荷给APP层。
接着，进入步骤610，APP根据本节点的节点号和复用微帧端口号与IP地址和UDP端口号的对应关系中获取该数据帧所对应的IP地址和UDP端口号，并获取MUX-AL的净荷，作为完成FP帧数据的接收过程。
本发明的第四实施方式涉及移动通信网络中Iub接口数据传输系统，包含源节点和目标节点。
在源节点内包含：判断模块，用于判断发送的数据帧是否小于指定长度；封装模块，用于根据预先在目标节点的IP层的下层设置的对应于该目标节点的IP地址和UDP端口号的节点号，或节点号和复用微帧端口号，在IP层的下层对数据帧进行封装；以及发送模块，用于将封装模块封装后的数据帧发送给目标节点。
目标节点内包含查找接收模块，用于根据收到的数据帧的节点号或节点号和复用微帧端口号找到相应的IP地址和UDP端口号，完成该数据帧的接收。
具体地说，源节点的判断模块在封装模块对数据帧进行封装前，先判断该数据帧是否小于指定长度，如果是，则指示该数据帧由复用适配层进行适配，否则，指示该帧协议数据帧由直接适配层进行适配。
对于由直接适配层进行适配的数据帧，封装模块使用目标节点的节点号在IP层的下层对该数据帧进行封装，目标节点的查找接收模块根据收到的数据帧的节点号找到相应的IP地址和UDP端口号，完成该数据帧的接收；对于由复用适配层进行适配的数据帧，封装模块使用目标节点的节点号和复用微帧端口号在IP层的下层对该数据帧进行封装，目标节点的查找接收模块根据收到的数据帧的节点号和复用微帧端口号找到相应的IP地址和UDP端口号，完成该数据帧的接收。从而解决了Iub接口的上层数据在SDTP中承载的问题，使得信息数据能以SDTP的方式进行承载与发送，从而提高了Iub接口的传输效率。由于传输效率的提高将直接降低投资成本和运营成本，因此可提高运营商的赢利能力。
虽然通过参照本发明的某些优选实施方式，已经对本发明进行了图示和描述，但本领域的普通技术人员应该明白，可以在形式上和细节上对其作各种改变，而不偏离本发明的精神和范围。
