Description

一种实现GSM和LTE系统间干扰处理的方法和装置 技术领域
本发明涉及无线通信技术领域，具体涉及一种实现全球移动通讯(GSM，Global System For Mobile Communication)系统和长期演进(LTE，Long Term Evolution)系统间干扰处理的方法和装置。
背景技术
随着无线通信技术的迅速发展以及无线通信业务的不断丰富，人们对无线业务以及无线通信设备的需求与日俱增，从而导致有限的频谱资源日趋匮乏。同时传统的GSM系统的用户越来越少，提供更高数据传输速率的LTE系统的用户越来越多，这使得GSM系统的频谱大量空闲，而LTE系统的频谱不够用。为了满足市场的需求，运营商正在从根本上改变他们利用现有频谱的方式，频谱重整(spectrum refarming)便是其中一种。
频谱重整是解决业务需求指数增长与频谱资源有限之间的矛盾的一种方式，利用频谱重整可以提升频谱的利用效率和灵活性，将GSM系统空闲的频谱资源借给能提供更高数据传输速率的LTE系统，包括以下几种实现方式：
1)将GSM系统的下行空闲频谱借给LTE频分复用(FDD，Frequency Division Duplexing)下行，将GSM系统的上行空闲频谱借给LTE FDD上行；
2)将GSM系统的下行空闲频谱借给时分LTE(TD-LTE，Time Division Long Term Evolution)；
3)将GSM系统的上行空闲频谱借给TD-LTE；
4)将GSM系统的上下行空闲频谱借给TD-LTE。
由此可以看出，GSM系统的上行空闲频谱可以借给LTE FDD上行，也可以借给TD-LTE。
然而，由于GSM系统用户分布的不均匀性，可能一个区域的GSM频谱空闲，而另一个区域的GSM频谱并不空闲。图1为现有技术中GSM小区上行干扰LTE小区的示意图，如图1所示，假设890～900MHz是区域A和区域B中GSM系统的频谱，在区域A中，由于GSM系统用户数大量减少，GSM系统频谱中的895～900MHz的5MHz频谱逐渐空闲；而区域B中GSM系统用户数变化较少，因此区域B中的GSM系统频谱并不空闲。当GSM系统的上行空闲频谱895～900MHz借给区域A中靠近区域B的LTE FDD小区A上行使用时，与区域B中靠近区域A的GSM小区B的上行工作频点898MHz(带宽200kHz)恰好交叠，因此，GSM小区B的上行可能对LTE FDD小区A的上行产生干扰，LTE FDD小区A的上行也可能对GSM小区B的上行产生干扰；图1中的实线箭头线表示有用信号，虚线箭头线表示干扰信号。同样，当GSM系统的上行空闲频谱895～900MHz借给区域A中靠近区域B的TD-LTE小区A使用时，GSM小区B的上行也会对TD-LTE小区A的上行产生干扰，TD-LTE小区A的上行也可能对GSM小区B的上行产生干扰。
目前，对干扰进行处理的方法是通过在区域A和区域B之间规划一个缓冲带(buffer zone)，在缓冲带内设置GSM系统和LTE系统都不能使用GSM系统的上行空闲频谱，或者部分地使用GSM系统的上行空闲频谱(即LTE小区从其工作频段中剔除与其有干扰关系的GSM小区的工作频谱)。该方案虽然解决了干扰问题，但存在频谱资源的浪费。

具体实施方式
本发明实施例中，GSM基站控制器确定时频资源干扰信息之后，将所述确定的时频资源干扰信息发送给LTE基站；所述时频资源干扰信息作为所述LTE基站进行干扰处理的依据。
下面通过附图及具体实施例对本发明做进一步的详细说明。
实施例一
本发明实施例一提供了一种实现GSM和LTE系统间干扰处理的方法，如图2所示，该方法包括以下步骤：
步骤201：GSM基站控制器确定时频资源干扰信息；
具体的，GSM基站控制器可通过以下方式中的至少之一来确定时频资源干扰信息：
方式一：GSM基站控制器根据下属小区每个上行工作频点的被干扰情况，确定被干扰的GSM小区的位置、被干扰的GSM用户、被干扰的GSM用户后续的时频资源调度信息、以及被干扰的GSM用户后续的时频资源调度信息索引，从而确定时频资源干扰信息；
方式二：GSM基站控制器接收LTE基站发送的上行被干扰指示信息，根据所述上行被干扰指示信息，确定在所述上行被干扰指示信息指示的时频资源上产生干扰的GSM用户、产生干扰的GSM用户后续的时频资源调度信息、以及产生干扰的GSM用户后续的时频资源调度信息索引，从而确定时频资源干扰信息。
其中，所述GSM基站控制器下属小区每个上行工作频点的被干扰情况，可通过以下方式之一来描述：载干比(C/I，也称为干扰保护比)、误码率(SER，Symbol Error Rate)、误比特率(BER，Bit Error Rate)；例如，GSM用户的载干比C/I低于特定门限，或者GSM用户的误码率SER 超过特定门限，或者GSM用户的误比特率BER超过特定门限，就认为该GSM用户受到了严重干扰。
所述上行被干扰指示信息包括以下至少之一：被干扰频域信息、被干扰时域信息、被干扰小区位置；
其中，所述被干扰频域信息指被干扰频域范围，可以表示为中心频点及被干扰物理资源块信息，或者一个或多个用起始频率和终止频率表示的频段，或者一个或多个用起始频率和频段宽度表示的频段；所述被干扰物理资源块信息可以用物理资源块编号和小区整个带宽包含的物理资源块数量来表示；或者，用所有物理资源块的bitmap序列来表示，例如，用1表示被干扰物理资源块，0表示没有被干扰物理资源块；
所述被干扰时域信息指被干扰时间范围，可以表示为子帧号及其所在的无线帧的起始时间，或者时隙号及其所在的无线帧的起始时间，或者起始时间、持续时间及周期，或者一个或多个用起始时间和结束时间表示的时间段，或者一个或多个用起始时间和持续时间表示的时间段；
在实际实现过程中，当所述上行被干扰指示信息同时包含被干扰频域信息和被干扰时域信息时，是指用成对的频域和时域表示的被干扰时频资源。
所述后续的时频资源调度信息包括：资源的时域调度信息和资源的频域调度信息，其中，所述时域调度信息可以表示为调度起始时间、持续时间及调度周期，或者一个或多个用调度起始时间和结束时间表示的时间段，或者一个或多个用调度起始时间和持续时间表示的时间段；所述频域调度信息可以表示为频点，或者开始频率和结束频率，或者绝对频道编号；
在实际实现过程中，所述GSM系统和LTE系统可以确定一个公共参考时间；所述起始时间和结束时间可以表示为相对于确定的公共参考时间的时间偏移；这里“后续”具体指从所述GSM用户即将被调度的时隙开始， 结束时间不定，因为GSM基站不知道该GSM用户业务什么时候结束，可以统计同类业务的GSM用户的平均服务时间，给出该时间内的GSM用户后续的时域调度信息，也可以不限制结束时间，例如以周期的形式描述GSM用户后续的时域调度信息；确定GSM用户后续时频资源调度信息，是为了让LTE基站根据该信息调整调度策略，避免该GSM用户之后再次被干扰。
所述GSM用户的标识可以用任何用于区分GSM用户的数字、字母或文字表示；所述GSM用户后续的时频资源调度信息索引与GSM用户是一一对应的，也可以用任何用于区分GSM用户的数字、字母或文字表示；例如，GSM用户1后续的时频资源调度信息索引表示为01；GSM用户2后续的时频资源调度信息索引表示为02。
所述时频资源干扰信息包括以下至少之一：产生干扰的GSM用户的标识、产生干扰的GSM用户后续的时频资源调度信息、产生干扰的GSM用户后续的时频资源调度信息索引、被干扰的GSM小区的位置、被干扰的GSM用户的标识、被干扰的GSM用户后续的时频资源调度信息、被干扰的GSM用户后续的时频资源调度信息索引。
在本发明的一个应用场景中，如果GSM基站控制器下属小区中的GSM小区A有两个GSM用户(GSM用户1和GSM用户2)在频点898MHz上的载干比C/I低于其门限值(9dB)，则被干扰的GSM小区就是GSM小区A，其位置可以用其接收天线所在位置表示，被干扰的GSM用户就是GSM用户1和GSM用户2，然后GSM小区A根据调度算法，确定所述GSM用户后续的时频资源调度信息，即在频点898MHz上GSM用户1和GSM用户2从即将被调度的时隙开始，使用频点898MHz进行上行数据发送的时间段。
在本发明的另一个应用场景中，假设上行被干扰指示信息包含被干扰频域信息、被干扰时域信息和被干扰小区位置，则确定产生干扰的GSM用 户、以及确定产生干扰的GSM用户后续的时频资源调度信息的具体实现过程如下：首先，GSM基站控制器根据被干扰频域信息确定产生干扰的频点；然后，根据被干扰小区位置，找出距离被干扰小区一定范围内使用该频点的GSM小区，即可能是干扰源的GSM小区；最后，判断这些GSM小区在产生干扰的频点的被干扰时域内是否调度了边缘用户，如果是，则被调度的边缘GSM用户就是产生干扰的GSM用户，然后GSM小区根据调度算法，确定这些产生干扰的GSM用户后续的时频域资源调度信息。
步骤202：GSM基站控制器将所述确定的时频资源干扰信息发送给LTE基站；所述时频资源干扰信息作为所述LTE基站进行干扰处理的依据。
具体的，所述LTE基站根据所述时频资源干扰信息进行干扰处理包括：

实际实现过程中，所述LTE基站在所述GSM用户后续的时频资源调度信息对应的物理资源块上不调度任何用户，是指LTE基站不分配所述GSM用户后续的时频资源调度信息对应的物理资源块给任何LTE用户。所述LTE基站不进行任何处理，是指LTE基站的调度方案不受所述时频资源干扰信息的影响，所述LTE基站按照自己原有的调度方式进行用户的调度。
在本发明的一个应用场景中，所述LTE基站根据时频资源干扰信息进行干扰处理包括：所述LTE基站在产生干扰的GSM用户后续的时频资源调度信息对应的物理资源块不调度任何用户，或者仅调度位于小区中心的用户。
在本发明的另一个应用场景中，所述LTE基站根据时频资源干扰信息进行干扰处理包括：所述LTE基站判断被干扰的GSM小区的位置是否在 LTE小区的干扰范围内，如果是，则LTE基站在被干扰的GSM用户的后续的时频资源调度信息对应的物理资源块不调度任何用户，或者仅调度位于小区中心的用户；如果否，LTE基站不进行任何处理；
实际实现过程中，LTE小区的干扰范围指的是以LTE小区的位置为中心的圆形区域；所述LTE基站判断被干扰的GSM小区的位置是否在LTE小区的干扰范围内，具体为：所述LTE基站计算被干扰的GSM小区的位置与该LTE小区的位置之间的距离；判断所述距离是否小于LTE小区干扰圆形区域的半径，如果小于，则认为被干扰的GSM小区的位置在LTE小区的干扰范围内；如果不小于，则认为被干扰的GSM小区的位置不在LTE小区的干扰范围内；
另外，所述判断操作也可以在LTE基站的上层节点进行，这时LTE的上层节点仅将被干扰的GSM小区的位置及相应的被干扰GSM用户信息发送给对其产生干扰的LTE基站；这里，所述LTE基站的上层节点可以为：移动性管理实体(MME，Mobility Management Entity)、或服务网关(S-GW，Serving GateWay)、或新增的集中式控制节点等网络实体。
在本发明的另一个应用场景中，所述LTE基站根据时频资源干扰信息进行干扰处理包括：所述LTE基站判断被干扰GSM用户后续的时频资源调度信息是否与LTE小区边缘用户后续的时频资源调度信息一致，如果是，则LTE基站在被干扰的GSM用户的后续的时频资源调度信息对应的物理资源块不调度任何用户，或者仅调度位于小区中心的用户；如果否，LTE基站不进行任何处理；
实际实现过程中，所述LTE基站可以通过以下方式判断被干扰GSM用户后续的时频资源调度信息是否与LTE小区边缘用户后续的时频资源调度信息一致：对于被干扰GSM用户的每个被干扰的上行频点，所述LTE基站计算在该频点对应的频段上LTE小区边缘用户被调度的上行子帧内， 被干扰GSM用户被调度的累积时间长度；判断所述累积时间长度与该子帧时间长度的比值是否超过设定门限值(例如门限值为70％)，如果超过，则认为被干扰GSM用户后续的时频资源调度信息与LTE小区边缘用户后续的时频资源调度信息一致；否则认为不一致。
进一步的，在GSM基站控制器将所述确定的时频资源干扰信息发送给LTE基站之后，所述方法还可以包括：
步骤203：GSM基站控制器接收LTE基站根据所述时频资源干扰信息进行干扰处理的响应消息；其中，所述响应消息包括：是否进行干扰处理的标识。实际实现过程中，进行干扰处理的标识和不进行干扰处理的标识，可以设置成任何用于区分是否进行干扰处理的字母、数字或文字等，例如，可以设置为当标识为1时表示已进行干扰处理，当标识为0时表示不进行干扰处理。
进一步的，所述方法还可以包括：
步骤204：GSM基站控制器向LTE基站发送时频资源干扰信息无效指示消息；其中，所述时频资源干扰信息无效指示消息用于指示时频资源干扰信息失效。实际实现过程中，可以提前设置时频资源干扰信息的失效条件，例如GSM用户业务结束、切换到其它小区、调度发生改变等，一旦满足失效条件，GSM基站控制器就向LTE基站发送时频资源干扰信息无效指示消息；
所述时频资源干扰信息无效指示消息包括以下至少之一：时频资源干扰信息无效的GSM用户标识、无效的GSM用户后续的时频资源调度信息、无效的GSM用户后续的时频资源调度信息索引。
实际实现过程中，上述步骤203和步骤204的执行顺序不限；步骤204可以在步骤203之后执行，也可以在步骤203之前或同时执行。
进一步的，上述实现GSM和LTE系统间干扰处理的方法中，所述GSM 基站控制器和LTE基站之间信息交互的方式包括以下至少之一：通过核心网网元、网管网元、直接接口、集中式控制节点。

步骤700：eNB发送上行被干扰指示信息给BSC；其中，eNB经过EMS1、NMS1、NMS2、EMS2将所述上行被干扰指示信息发送给BSC；
具体的，eNB下属小区当前上行被干扰情况为LTE小区的频段897.95MHz到898.13MHz间断性地被干扰，而该频段对应的恰好是GSM 系统的频点898MHz，eNB根据被干扰情况，判断可能是相邻GSM小区造成的干扰，因此确定向BSC发送上行被干扰指示信息；所述上行被干扰指示信息包括：被干扰频域信息(897.95MHz到898.13MHz)；被干扰时域信息(起始时间1为T+2ms，结束时间1为T+3ms；起始时间2为T+5ms，结束时间2为T+6ms)；被干扰小区位置(东经43度，北纬56度)。
步骤701：BSC根据上行被干扰指示信息确定时频资源干扰信息；
具体的，BSC接收到上行被干扰指示信息之后，根据上行被干扰指示信息中的被干扰频域信息确定产生干扰的频点为898MHz，然后根据被干扰小区位置，找出距离被干扰小区一定范围内使用该频点的GSM小区，这些GSM小区就是可能产生干扰的小区，假设有两个GSM小区：Cell2和Cell3，然后分别判断Cell2和Cell3在频点898MHz的被干扰时域上是否调度了边缘用户，假设判断结果为Cell2在频点898MHz的被干扰时域上调度了边缘用户，则Cell2就是产生干扰的GSM小区，在所述被干扰时域内被调度的边缘用户就是产生干扰的GSM用户；
BSC根据Cell2中在频点898MHz的被干扰时域上调度的边缘用户的时域调度信息，确定时频资源干扰信息包括：产生干扰的GSM用户3后续的时频资源调度信息：频点为898MHz，起始时间为T+2ms，持续时间为1.2ms，调度周期为3ms；产生干扰的GSM用户3后续的时频资源调度信息索引03。

具体的，eNB根据产生干扰的频点898MHz、产生干扰的GSM用户后续的时域资源调度信息及其索引，并结合下属小区的受干扰情况，确定在GSM小区产生干扰的时频资源上eNB下属小区被干扰了，因此eNB决定在GSM小区产生干扰的时频资源对应的物理资源块上仅调度位于小区中 心的用户，避免被GSM系统的干扰。
示例三
图8为该示例三的流程图，如图8所示，eNB和BSC之间通过新建接口传递信息，该示例包括以下步骤：
步骤800：eNB向BSC发送上行被干扰指示信息；
具体的，eNB根据下属小区当前上行被干扰情况：LTE CellA小区的中心频点为897.5MHz，被干扰物理资源块的bitmap序列为(1000000000000000000000000)，即第一个物理资源块被干扰，eNB及相邻eNB对被干扰频段895.43～895.61MHz设置静默期，例如静默期为T+1ms开始，静默持续时间为9.2ms，LTE基站判断静默期内测量的被干扰频段上的信号功率强度超出了功率阈值，因此判断可能是相邻GSM小区造成的；因此确定上行被干扰指示信息为：被干扰频域信息为被干扰中心频点为897.5MHz，被干扰物理资源块的bitmap序列为(1000000000000000000000000)，被干扰小区位置为(东经43度，北纬56度)。
步骤801：BSC根据上行被干扰指示信息和BSC下属小区每个上行工作频点被干扰情况确定时频资源干扰信息；
具体的，BSC接收到上行被干扰指示信息之后，根据上行被干扰指示信息中的被干扰频域信息确定产生干扰的频点为895.6MHz，则使用该频点的GSM小区就是可能产生干扰的GSM小区，假设使用该频点的GSM小区有两个：Cell4和Cell5，然后判断LTE被干扰小区位置是否在Cell4或Cell5的干扰范围内，判断结果为LTE被干扰小区位置在Cell4的干扰范围内，也在Cell5的干扰范围内，因此产生干扰的小区为Cell4和Cell5，根据Cell4和Cell5用户调度情况，确定产生干扰的GSM用户、产生干扰的GSM用户后续的时频资源调度信息及其索引。确定产生干扰的GSM小区的方法 取决于具体的实现算法，也可以根据Cell4和Cell5在频点895.6MHz上的被干扰情况，确定产生干扰的GSM小区，这里不再详述。另外BSC还根据下属小区每个上行工作频点被干扰情况，确定被干扰的GSM小区的位置、被干扰的GSM用户、被干扰的GSM用户后续的时频资源调度信息及其索引；

步骤802：BSC将时频资源干扰信息发送给eNB；
步骤803：eNB接收到时频资源干扰信息之后，进行干扰处理；
具体的，eNB根据产生干扰的频点895.6MHz及产生干扰的GSM用户的时域调度信息，并结合下属小区的受干扰情况，确定在GSM小区产生干扰的时频资源上eNB下属小区被干扰了，因此eNB决定在产生干扰的GSM用户(GSM1、GSM2)后续的时频资源调度信息对应的物理资源块上不调度任何用户，避免被GSM系统的干扰；
eNB根据被干扰的GSM小区的位置和LTE小区的干扰范围，判断被干扰的GSM小区位于LTE小区的干扰范围内，eNB在被干扰的GSM用户 (GSM3)的后续的时频资源调度信息对应的物理资源块不调度任何用户，或者仅调度位于小区中心的用户，从而避免对GSM系统产生干扰。
步骤804：BSC向eNB发送时频资源干扰信息无效指示消息；
具体的，当GSM用户1切换到其他GSM小区时，BSC向eNB发送时频资源干扰信息无效指示消息，其中时频资源干扰信息无效指示消息包含无效的GSM用户1后续的时频资源调度信息，即产生干扰的GSM用户1后续的时频资源调度信息：频点为895.6MHz，起始时间为T+0.5ms，持续时间为1ms，调度周期为10ms；eNB收到该消息后调整对下属用户的调度，例如不再限制GSM用户1后续的时域调度信息对应的物理资源块上的调度操作。

其中，时频资源干扰信息包括：被干扰的GSM小区的位置(东经40度，北纬50度)，被干扰的GSM用户的标识GSM01，GSM01后续的时频资源调度信息(绝对频道编号为40，起始时间为T+0.5ms，持续时间为1ms，调度周期为10ms)；
CCP根据时频资源干扰信息中被干扰的GSM小区的位置，确定可能对GSM小区产生干扰的LTE小区，确定方法可以是：以被干扰的GSM小区 的位置为中心，以LTE小区的干扰距离为半径画圆，位于圆内的LTE小区(即LTE小区覆盖区域的一部分或全部位于圆内)就是可能对GSM小区产生干扰的LTE小区；当然也可以采用其他的方法，这里不做限制；具体LTE小区的干扰半径可以根据网络规划要求和LTE小区的eNB类型预定义，然后将时频资源干扰信息发送给对GSM小区产生干扰且工作频段与被干扰的GSM频点有交叠的LTE小区的eNB。
步骤902：eNB接收到时频资源干扰信息之后，进行干扰处理；
具体的，eNB根据被干扰的绝对频道编号40，查找对应的被频点为898MHz，在该频点上GSM小区被干扰用户后续的时域资源调度信息对应的物理资源块上不调度任何用户。

具体的，eNB判断被干扰GSM用户1和GSM用户2后续的时频资源调度信息是否与LTE小区边缘用户后续的时频资源调度信息一致，当判断结果为一致时，eNB在被干扰的GSM用户1和GSM用户2的后续的时频资源调度信息对应的物理资源块不调度任何用户，或者仅调度位于小区中心的用户，从而避免对GSM系统产生干扰。
步骤1003：BSC向eNB发送时频资源干扰信息无效指示消息；
具体的，当GSM用户1切换到其他GSM小区时，BSC发送时频资源干扰信息无效指示消息，其中时频资源干扰信息无效指示消息包括：无效的GSM用户后续的时频资源调度信息索引01，eNB收到该消息后调整对下属用户的调度，例如不再限制GSM用户1后续的时频资源调度信息对应的物理资源块上的调度操作。
上述各个示例中，确定LTE小区干扰范围的方法为：首先根据GSM系统的干扰容忍计算干扰功率门限；然后计算接收到的LTE基站发射的信号功率高于干扰功率门限区域，该区域即LTE小区的干扰范围。LTE小区的干扰范围可以预先设置，也可以采用其他方法计算干扰范围，这里不做限 制。
另外，上述各个示例中，LTE小区的干扰距离指LTE基站到干扰范围边界的最大距离；同样的，GSM小区的干扰范围的确定方法与LTE小区类似。
