Description

一种控制双连接X2状态报告发送的方法、装置及辅基站 技术领域

目前标准上对于TDD-FDD Joint Operation(时分双工-频分双工的共享操作)主要有CA(有条件接收)和双连接两种方案，其中CA属于紧耦合、基带处理层面的协作，不适合异厂家。而双连接方案支持非理想backhual(双向回环链路)，不需要共站，支持异厂商互联，组网图如图1。
当核心网EPC(Evolved Packet Core，分组核心演进)给终端UE发送数据的过程中，数据首先会到达主基站MeNB，然后MeNB会根据流控算法把一部分或者是全部数据报文通过X2链路(主辅基站之间的一种通信链路)发给辅基站SeNB，辅基站会给MeNB发送状态报告即X2DL DATA DELIVERY STATUS(X2DL数据传送状态)，此X2状态报告的作用是通知MeNB哪些报文有丢失需要重传，SeNB需要的数据量有多大以及哪些报文已经被成功发送。

如图2所示，本发明实施例的所述控制双连接X2状态报告发送的方法，应用于辅基站，包括：
步骤100，接收主基站发送的X2数据报文，实时判断向所述主基站发送X2状态报告的预设时机是否到达；
步骤200，当发送X2状态报告的预设时机到达时，发送X2状态报告给所述主基站。
本文上述方案，通过依据发送时机对辅基站的X2状态报告进行发送控制，使得X2状态报告的发送能够更加合理、准确、及时，避免了因X2状态报告反馈的过于频繁而造成占用X2链路带宽；或者因X2状态报告反馈不及时而造成辅基站上数据量不足甚至断流或是主基站上存储报文过多而溢出丢包断流的情况。
主基站通常将X2数据报文按照预设的格式进行发送，所述X2数据报文的发送格式如表1所示：
Figure PCTCN2015095684-appb-000001
Figure PCTCN2015095684-appb-000002
表1 X2数据报文的发送格式
其中，发送的所述X2数据报文中包括：用1个字节标识的PDU Type(协议数据单元类型)、用两个字节标识的X2-U Sequence Number(X2-U序列号)以及预设0-4字节的备用扩展字段。
在向主基站反馈X2状态报告时，所述X2状态报告中包含X2数据报文的接收状况，因此本发明的又一实施例中，所述方法还包括：
在接收主基站发送的X2数据报文时，实时记录所述X2数据报文的接收状况。
所述接收状况主要为辅基站接收到的X2数据报文是否连续，如果不连续，需要反馈给主基站，以使主基站重新发送丢失的X2数据报文，因此，所述在接收主基站发送的X2数据报文时，实时记录所述X2数据报文的接收状况的步骤包括：
在接收主基站发送的X2数据报文的过程中，检测接收到的X2数据报文的序列号是否连续，若所述X2数据报文的序列号不连续，将不连续报文段的个数的记录值进行加1计数。
在接收状态的记录中，记录的不仅仅是不连续报文段的个数，同时还将不连续的X2数据报文的序列号进行记录。
例如，默认的X2数据报文接收序列应为1-20，但X2数据报文的实际接收为1-3、6-9、11-17、20，根据上述接收状况，不连续报文段的个数的记录值为3，且记录的不连续的序列号为：4-5、10、18-19。
所述X2状态报告的格式如表2所示：
Figure PCTCN2015095684-appb-000003
Figure PCTCN2015095684-appb-000004
表2X2状态报告格式
其中，发送的所述X2状态报告中包括：用1个字节标识的标识信息，所述标识信息包括PDU Type(协议数据单元类型)、最后一帧的识别码(Final Frame Ind)和是否是丢失的数据包报告(Lost Packet Report)；2个字节标识的最高成功交付PDCH的序列号(Highest successfully delivered PDCP Sequence Number)；4个字节标识的E-RAB所需缓存区的大小(Desired buffer size for the E-RAB)；4个字节标识的UE所需的最小缓存区的大小(Minimum desired buffer size for the UE)；1个字节标识的失去X2-U序列号报告范围的数量(Number of lost X2-U Sequence Number ranges reported)；失去X2-U序列号的开始范围(Start of lost X2-U Sequence Number rang)以及失去X2-U序列号的结束范围(End of lost X2-U Sequence Number range)；预设0-4字节的备用扩展字段。
发送所述X2状态报告的预设时机可以分为：计时时间到达定时时间、不连续报文段的个数的记录值达到预设个数、接收到无线链路控制RLC协议层反馈的成功接收所述数据报文的状态报告三种情况。
本发明实施例一中，发送所述X2状态报告的预设时机为：计时时间到 达定时时间；
则所述步骤100包括：
在接收主基站发送的X2数据报文的过程中，进行总接收时间的记录；
实时将总接收时间与定时时间进行比较，得到接收时间是否到达定时时间的比较结果。
在实施例一中，在接收X2数据报文的过程中开始计时，并实时的将计时时间与定时时间进行比对，当计时时间达到定时时间时，就向主基站发送X2状态报告；其中，当计时时间达到定时时间，向主基站发送X2状态报告时，辅基站会重新进行X2数据报文的接收计时，此计时过程是循环进行的。
为了保证能顺利实现辅基站的定时，本发明实施例一的所述方法，在所述步骤100之前，所述方法还包括：
接收所述主基站发送的添加所述辅基站的请求；
根据辅基站自身的资源分配情况，判断所述请求是否为允许被接受；
若所述请求允许被接受，则建立针对所述请求的状态报告定时器，并设置所述报告定时器的预设时间，所述预设时间为状态报告定时器的定时时间。
结合上述实施例，如图3所示，本发明实施例一的实现方式为：
步骤1.1，MeNB发送SeNB添加请求；
步骤1.2，SeNB如果判断资源可以接纳，则会进行实例建立并且配置状态报告定时器，可选地，所述配置状态报告定时器的定时时间默认为5ms；
步骤1.3，SeNB向MeNB反馈应答消息；
步骤1.4，MeNB将X2数据以X2数据报文格式持续发送给SeNB；
步骤1.5，SeNB检测X2序列号是否连续，如果不连续则记录非连续报文段的个数，并下发报文给RLC(Radio Link Control)协议层；同时，SeNB实时判断状态报告定时器是否超时；
步骤1.6，等待状态报告定时器超时，SeNB会按照表2中的格式发送X2 状态报告给MeNB。
本发明实施例二中，发送所述X2状态报告的预设时机为：不连续报文段的个数的记录值达到预设个数；
则所述步骤100包括：
将所述不连续报文段的个数的记录值与所述预设个数进行比较，得到不连续报文段的个数是否达到所述预设个数的比较结果。
在实施例二中，当记录得到不连续报文段的个数达到了预设值，辅基站便需要向主基站发送X2状态报告；其中，当不连续报文段的个数达到预设值，向主基站发送X2状态报告时，辅基站会重新进行X2数据报文不连续报文段个数的计数，此计数过程是循环进行的。
如图4所示，本发明实施例二的实现方式为：
步骤2.1，MeNB发送SeNB添加请求；
步骤2.2，SeNB如果判断资源可以接纳，则会进行实例建立并且配置状态报告定时器，可选地，所述配置状态报告定时器的定时时间默认为5ms；
步骤2.3，SeNB向MeNB反馈应答消息；
步骤2.4，MeNB将X2数据以X2数据报文格式持续发送给SeNB；
步骤2.5，SeNB检测X2序列号是否连续，如果不连续则记录非连续报文段的个数，并下发报文给RLC协议层；同时，SeNB实时判断记录的非连续报文段个数是否大于等于4个；
步骤2.6，当记录的非连续报文段个数大于等于4个时，SeNB会按照表2中的格式发送X2状态报告给MeNB(在X2状态报告中携带的丢失段最大为256)。
本发明实施例三中，发送所述X2状态报告的预设时机为：接收到无线链路控制RLC协议层反馈的成功接收所述数据报文的状态报告；
则所述判断向主基站发送X2状态报告的预设时机是否到达的步骤包括：
实时监测是否接收到RLC协议层反馈的成功接收所述数据报文的状态报 告。
辅基站在接收到RLC协议层反馈的状态报告时，则证明X2数据报文已成功被终端接收，此时辅基站需要通知主基站将成功被接收的X2数据报文删除。
如图5所示，本发明实施例三的实现方式为：
步骤3.1，MeNB发送SeNB添加请求；
步骤3.2，SeNB如果判断资源可以接纳，则会进行实例建立并且配置状态报告定时器，可选地，所述配置状态报告定时器的定时时间默认为5ms；
步骤3.3，SeNB向MeNB反馈应答消息；
步骤3.4，MeNB将X2数据以X2数据报文格式持续发送给SeNB；
步骤3.5，SeNB检测X2序列号是否连续，如果不连续则记录非连续报文段的个数，并下发报文给RLC协议层；同时，实时检测是否收到RLC反馈的状态报告；
步骤3.6，当SeNB收到RLC反馈的状态报告时，会按照表2中的格式发送X2状态报告给MeNB。
应用上述方法的辅基站既可以只通过实施例一、实施例二或实施例三的方式上报所述X2状态报告；也可以实施例一和实施例二并存、实施例一和实施例三并存或者实施例二和实施例三并存的方式上报所述X2状态报告；同时也可以同时包括实施例一、实施例二和实施例三中所述的方式上报所述X2状态报告；选用哪种组合方式，可根据实际需求状况进行制定。
本文上述方案，状态报告的时长配置可以根据不同系统的实现进行，这样可以使得定时器时长更加合理；且状态报告定时发送充分利用目前协议规定的格式进行，不会造成链路中存在大量状态报告的情况，不会占用过多的X2链路带宽。
对应于上述方法，如图6所示，本发明实施例还提供一种控制双连接X2状态报告发送的装置，应用于辅基站，包括：
