随着无线通信技术的进步和社会经济的发展， 各行各业对无线频谱资源 的需求越来越大， 造成了无线频谱资源的稀缺性。 应用于铁路通信数字移动 通信系统（GSM for Railways, GSM-R ) 系统无线频谱只有 4M带宽， 无线频 谱资源就显得更加珍贵。
随着铁路路网建设的不断发展， 铁路专用移动通信系统成为现代化铁路 的神经中枢， 同时也对系统的安全性、 可靠性及高效运营提出了更高的要求。 GSM-R网络无线覆盖也需要通过冗余方式提高可靠性，交织冗余覆盖方式（每 个基站都能覆盖到相邻的基站， 保证一个基站故障时， 相邻基站的信号仍然 能够支持业务）在 GSM-R网络建设中得到广泛应用。
铁路通信对于网络的可靠性要求非常高， 交织冗余覆盖方式可以提高网 络的可靠性。
在铁路链型覆盖的典型场景下， 常用 S2 ( Sector 2 )组网方式实现铁路链 型覆盖， 其中， 所述 S2组网方式具体实现为： 小区包含 2个载频， 小区天线 沿铁路线向两边打， 两边的信号相同 （小区的形成示意图如图 1所示）， 理论 上多个小区满足交织冗余覆盖 S2组网， 形成的交织冗余覆盖铁路链可以是图 2所示的结构。
在铁路链型覆盖场景下、 如图 2所示， 交织冗余覆盖的邻区关系如下： 小区 1的邻区有： 小区 2和小区 3 (由于图 2左侧没有画完整， 实际小区 1的左侧还有 2个邻区）； 小区 2的邻区有： 小区 1、 小区 3和小区 4 (由于图 1左侧没有画完整， 实际小区 2的左侧还有 1个邻区）；
小区 3的邻区： 小区 1、 小区 2、 小区 4和小区 5;
小区 4的邻区： 小区 2、 小区 3、 小区 5和小区 6;
以下小区的邻区依次类推： 除了铁路线两头的小区外， 其他小区都会存 在前后各 2个邻区， 单方向上每个小区都有 2个邻区。
如图 3所示： S2组网方式（每个小区需要 2个频点）， GSM-R网络要求 相邻小区不能同频 （频点相同 ) 和邻频 （频点相邻）， GSM-R 频率间隔为 200KHz,那么，满足上述条件的前提下，要实现铁路链型覆盖最少需要 2.2MHz ( 200k*ll=2.2M )连续频语。
在上述 2.2MHz以及频率间隔为 200KHz的前提下，铁路链型覆盖的频点 规划可以是： 频谱中间第 "1" 个至第 "11" 个频点分为 "ABC" 3组， 每组 2个频点 (如表 1所示）：

表 1
每个小区单向上有 2个邻区， 不能同邻频； 如果小区 1为 A组频点（fl、 β ): 小区 2不能使用 "Α" 组频点 （使用 Α组频点则会导致小区 1和小区 2 同频， 会导致两个小区的干扰过大）和与 "A" 组频点相邻的频点， 小区 2能 使用 "B" 组频点 （f5、 f7 );
同理， 小区 3不能和小区 1和小区 2同邻频， 小区 3只能使用 "C" 组频 点 （©、 fll );
小区 4可以复用小区 1的频点（两个小区不互为邻区）， 小区 5可以使用 复用小区 2频点， 这样在一条交织冗余覆盖链上各小区频点的复用方式就可 以是： ABCABC ... ... , 在该复用方式下至少需要 2.2MHz连续频谱才能形成 一条交织冗余覆盖链。 综上所述， 如果相隔距离近的两个小区使用相同或者是相邻的频点， 则 会导致小区的同邻频干扰比较大。 如果按照上述图 2所示的交织冗余组网方 式， 则会出现频谱利用率低， 链型 S2组网场景下， 最少需要 2.2M频谱才能 实现交织冗余覆盖， 应用受限的问题。 发明内容

现有技术所提供的铁路链型覆盖的典型场景下， 任一小区的邻区不能同 频或者邻频， 所以会导致交织冗余组网方式的频谱利用率低。
针对上述问题本发明提供一种实现交织冗余覆盖的装置， 该装置包括： 间隔距离确定模块， 用于根据预设的干扰距离间隔值， 确定两个相隔小 区之间的间隔距离， 所述两个间隔小区的间隔距离不小于所述干扰距离间隔 值时， 小区同邻频干扰小于预设的干扰阔值；
多站点共小区设置模块， 用于根据所述间隔距离在所述两个间隔小区之 间设置一个包括至少两个位置组的多站点共小区； 所述多站点共小区和所述 两个间隔小区中的两两相邻小区交织实现链型冗余覆盖， 而且多站点共小区 内两两相邻的位置组交织实现链型冗余覆盖。
在本发明实施例中， 链型覆盖条件下 （铁路、 公路等场景）， 使用包括多 个位置组的多站点共小区技术来实现小区的交织冗余覆。 从而扩大各小区的 间隔距离。 从而增大同频复用小区的距离， 进一步实现减小小区间的同频干 扰的效果。
为了更清楚的说明本发明的方案， 首先介绍一下本发明所应用的多站点 共小区技术， 通过以下多站点共小区技术形成的小区为多站点共小区， 具体 形成包括：
把多个不同物理站址的位置组 (subsite)设置为一个逻辑小区， 这样的小区 也称为级联小区。 位置组指归属于一个 BBU的多个 RRU/RFU在物理上覆盖 的某一个区域。 在高铁覆盖、 隧道覆盖或者室内覆盖等场景下， 级联小区可 以减少切换次数、 提高覆盖效率、 改善用户感受。
级联小区指一个 BBU下的多个位置组在物理上分属不同站址， 但是逻辑 上属于同一个小区。
级联小区承载在多个位置组上， 每个位置组的物理配置、 载波数、 频点 等小区参数均相同。 一个级联小区只有一个主位置组， 负责小区的管理和业 务的控制。 其它位置组为从位置组， 从位置组在主位置组的控制下完成可服 务载波的选择， 信道激活等小区服务功能。
移动台初始接入位置组时， 所有位置组分别计算移动台的上行信噪比 (Signal Noise Ratio), 并上报给主位置组， 主位置组经过判决， 选择信噪比最 佳的位置组作为服务位置组。
所有位置组会不断计算移动台的上行信噪比， 并上报给主 Subsite进行判 决， 当相邻位置组上报信噪比优于服务位置组上报的信噪比时， 触发位置组 切换。 MS在位置组间发生切换时， 釆取先连接新位置组， 再断开老位置组的 方式， 不中断业务， 实现无缝切换， 保证业务质量。
为使本发明实施例的目的、 技术方案和优点更加清楚， 下面将结合本发 明实施例中的附图， 对本发明实施例中的技术方案进行清楚、 完整地描述， 显然， 所描述的实施例是本发明一部分实施例， 而不是全部的实施例。 基于 本发明中的实施例， 本领域普通技术人员在没有作出创造性劳动前提下所获 得的所有其他实施例， 都属于本发明保护的范围。
实施例一、 本发明实施例提供一种实现交织冗余覆盖的装置， 该装置包 括（如图 4所示 )··
间隔距离确定模块 401 , 用于根据预设的干扰距离间隔值， 确定两个相隔 小区之间的间隔距离， 所述两个间隔小区的间隔距离不小于所述干扰距离间 隔值时， 小区同邻频干扰小于预设的干扰阔值；
多站点共小区设置模块 402 ,用于根据所述间隔距离在所述两个间隔小区 之间设置一个包括至少两个位置组的多站点共小区； 所述多站点共小区和所 述两个间隔小区中的两两相邻小区交织形成冗余覆盖链， 而且多站点共小区 内两两相邻的位置组交织实现链型冗余覆盖。
在本发明实施例中， 在链型覆盖场景下， 交织是指： 多站点共小区中各 站点的覆盖范围有交错区域； 冗余是指： 链型区域上的每一个点都至少有两 个站址的无线信号覆盖； 则所述交织冗余覆盖是指： 在链型覆盖的场景下， 站点交替排列， 每个覆盖点都至少有两个站址的无线信号覆盖， 提高可靠性。
为了保证每个覆盖点都有两个频点覆盖， 并且最大限度的节约资源， 则 所述多站点共小区设置模块 402将多站点共小区内两两相邻的位置组交织实 现链型冗余覆盖包括：
根据一预设规则确定两个目标位置组的交织覆盖区域， 其中， 所述两个 目标位置组之间间隔一个位置组， 所述预设规则为所述两个目标位置组的交 织冗余覆盖的区域面积大于零小于预设的冗余覆盖阔值。
虽然上述实施例中， 多站点共小区设置模块 402 中只出现了两个小区之 间的间隔小区为多站点共小区， 但是上述多站点共小区之间位置组的规划方 式适用于本发明方案中所提到的任一多站点共小区。
在本发明实施例所提供的上述三个小区 （该处的小区是上述方案中的提 到的多站点共小区和普通的小区总称） 只是现有覆盖链中一个最小的组成单 元， 在实际应用中可以在这个最小单元的两端增加新的小区从而实现足够长 度的链型覆盖网， 所以能够达到其他小区也实现同邻频干扰的目的， 本发明 实施例中还进一步的限定所述两个相隔小区的具体情况， 所以在该装置中： 所述间隔距离确定模块 401 还用于将所述两个相隔小区中的至少一个小 区设置为包括至少两个位置组的多站点共小区。
为了形成一条完整的覆盖链， 本发明实施例所提供的装置还包括： 覆盖链扩展模块 403 , 当添加新的多站点共小区时， 用于将所述新的多站 点共小区与所述两个相隔小区中的多站点共小区相邻交织， 使所述新的多站 点共小区添加到所述冗余覆盖链中。
另外， 因为小区间的同邻频干扰会受到两个小区之间的间隔距离影响， 所以本发明的方案利用多站点共小区技术增大小区间的间隔距离之后， 则可 以将相隔一个小区的两个相隔小区设置相同或相邻的频点 （现有技术中使用 普通小区布网， 间隔一个小区的两个相隔小区距离太近不能使用相同或相邻 的频点）， 从而能够有效的增大链型冗余覆盖的频谱利用率。 则本发明所提供 的装置还包括：
第一频点设置模块 404 ,用于将所述冗余覆盖链中任意两个交织小区的频 点设置为不相邻且不相同的频点。
基于本发明实施例所提供方案以及 S2 组网中相邻小区不能同邻频的要 求， 则本发明实施例中个小区频点的最优化规划可以是间隔一个小区的两个 相隔小区规划为相同或相邻的频点 , 所以本发明实施例中：
所述第一频点设置模块 404 ,还用于将所述冗余覆盖链中， 中间间隔一个 小区的两个相隔小区的频点分别设置为第一频点和第二频点， 并将间隔小区 之间的中间小区的频点设置为第三频点， 其中， 所述第一频点与第二频点为 相同或相邻的频点； 所述第三频点为与所述第一频点和第二频点都不相邻也 不相同的频点。
在本发明实施例中， 链型覆盖条件下 （铁路、 公路等场景）， 使用包括多 个位置组的多站点共小区技术来实现小区的交织冗余覆。 从而扩大各小区的 间隔距离。 从而增大同频复用小区的距离， 进一步实现减小小区间的同频干 扰的效果。
另外， 因为本发明所提供的方案中， 利用包括多个位置组的多站点共小 区代替现有技术中的普通小区， 从而使各小区 （即多站点共小区）之间的距 离增大。 因为小区间的同邻频干扰会受到两个小区之间的间隔距离影响， 所 以本发明的方案在增大小区间的间隔距离之后， 则可以将相隔一个小区的两 个小区设置相同或相邻的频点， 从而能够有效的增大链型冗余覆盖的频谱利 用率。
实施例二、 本发明实施例还提供一种实现交织冗余覆盖的方法， 该方法 包括（如图 5所示）：
步骤 501 ,根据预设的干扰距离间隔值， 确定两个相隔小区之间的间隔距 离， 所述两个间隔小区的间隔距离不小于所述干扰距离间隔值时， 小区同邻 频干扰小于预设的干扰阔值；
因为在一条交织冗余的覆盖链中， 覆盖链的两端可以是直接使用普通小 区， 所以本发明实施例所提供的覆盖链中最小的组成单元（三个交织小区） 中应该至少包括两个多站点共小区， 所以在本发明实施例中， 所述两个相隔 小区中的至少一个小区为包括至少两个位置组的多站点共小区。
步骤 502 ,根据所述间隔距离在所述两个间隔小区之间设置一个包括至少 两个位置组的多站点共小区； 所述多站点共小区和所述两个间隔小区中的两 两相邻小区交织形成冗余覆盖链， 而且多站点共小区内两两相邻的位置组交 织实现链型冗余覆盖。
在本发明实施例所提供的上述三个小区 （该处的小区是上述方案中的提 到的多站点共小区和普通的小区总称） 只是现有覆盖链中一个最小的组成单 元， 在实际应用中可以在这个最小单元的两端增加新的小区从而实现足够长 度的链型覆盖网， 所以能够达到其他小区也实现同邻频干扰的目的， 本发明 实施例中还进一步的限定所述两个相隔小区的具体情况， 所以在本发明实施 例中：
当添加新的多站点共小区时， 将所述新的多站点共小区与所述两个相隔 小区中的多站点共小区相邻交织， 使所述新的多站点共小区添加到所述冗余 覆盖链中。 述冗余覆盖链中任意两个交织小区的频点为不相邻且不相同的频点。
进一步， 因为本发明所提供的方法利用多站点共小区技术， 所以增加了 相隔小区之间的距离， 进而使得只是间隔一个小区的两个间隔小区即可适用 相同或者是相邻的频点。 所以所述冗余覆盖链中， 中间间隔一个小区的两个 相隔小区的频点分别为第一频点和第二频点， 间隔小区之间的中间小区的频 点为第三频点， 则所述第一频点与第二频点为相同或相邻的频点； 所述第三 频点是与所述第一频点和第二频点都不相邻也不相同的频点。 为了保证每个覆盖点都有两个频点覆盖， 并且最大限度的节约资源， 多 站点共小区内两两相邻的位置组交织实现链型冗余覆盖包括：
根据一预设规则确定两个目标位置组的交织覆盖区域， 其中， 所述两个 目标位置组之间间隔一个位置组， 所述预设规则为所述两个目标位置组的交 织冗余覆盖的区域面积大于零小于预设的冗余覆盖阔值。
为了详细说明本发明方案的具体实现， 以下结合具体的应用场景对本发 明所提供的方法作进一步详细的说明：
在本实施例中， 多站点共小区至少包含 2个位置组（只有一个位置组为 普通小区）， 每个多站点共小区具体包含几个位置组需要根据实际情况来决 定。 并且多站点共小区内两两相邻的位置组进行交织冗余覆盖； 当其中一个 位置组故障时， 其相邻的位置组信号可以覆盖故障位置组所覆盖的区域， 支 撑业务正常开展。
根据图 5所述的方法， 在进行多站点共小区实现交织冗余覆频率规划时， 具体实现可以是：
以第一个多站点共小区为起点， 所述第一个多站点共小区的频点规划为 Fl ( F1可能包含一个或多个频点）；
第二个多站点共小区由于与第一个多站点共小区相邻， 不能为 F1的同邻 频，那么第二个多站点共小区的频点规划为 F2( F2可能包含一个或多个频点 ), F2中任何一个频点都不能与 F1中任何一个频点同邻频；
第三个多站点共小区与第二个多站点共小区是邻区关系， 与第一个多站 点共小区存在一定的距离； 那么第三个小区的频点规划为 F3 ( F3可能包含一 个或多个频点 ):
F3中任何一个频点都不能与 F2中任何一个频点同邻频， F3中一个或者 多个频点可以与 F1中一个或者多个频点同邻频。
在该实施例中， 如果 F1包含的频点数多， 那么就使 F3为 F1的子集； 如 果 F3包含的频点数多， 那么就使 F1为 F3的子集。
如图 6所示的组网结构， 多站点共小区 1和多站点共小区 2互为邻区； 多站点共小区 1和多站点共小区 3不互为邻区可以同频复用； 其间隔为多站 点共小区 2覆盖距离， 多站点共小区至少 2个普通小区交织覆盖距离， 图 6 中多站点共小区 2有 6个位置组（在具体的应用环境中位置组的数量可以根 据实际的需求进行调整）， 理论上 6个位置组可以达到 6个普通小区交织覆盖 距离。
S2组网方式（每个小区需要 2个频点）， GSM-R网络要求相邻小区不能 同频（频点相同 )和邻频（频点相邻）， GSM-R频率间隔为 200KHz; 那么， 最少需要 1.4MHz ( 200k*7=1.4M )连续频谱（如图 7所示）， 两端第 "0" 个 频点作为隔离保护不使用。
在该实施例中可以将频点规划为： 将频谱中间第 "Γ 个至第 "7" 个频 点分为 "AB" 2组， 每组 2个频点 （S2组网要求）： 每个多站点共小区单向 上有 1 个邻区， 不能同邻频； 根据上述规划方法则多站点共小区交织冗余组 网频点分配可以是表 2所示的情况：
Figure imgf000014_0001
表 2
在该实施例中如果多站点共小区 1为 A组频点 （fl、 β ), 则多站点共小 区 2与多站点共小区 1相邻， 不能使用 Α组频点（同频）， 也不能使用相邻频 点， 多站点共小区 2能使用 B组频点 （f5、 f7 );
多站点共小区 3与多站点共小区 2相邻， 不能使用 B组频点（同频）， 也 不能使用相邻频点， 多站点共小区 3与多站点共小区 1 的间隔较大， 可以复 用多站点共小区 1的频点 A组频点 （fl、 B );
同理， 多站点共小区 4可以复用多站点共小区 2频点， 每两个相隔一个 多站点共小区的小区可以复用同一组频点： 在该实例中形成的交织冗余覆盖 链中各多站点共小区的频点使用可以是 AC AC方式。
利用上述方法实现的铁路交织冗余覆盖链路在 S2组网场景下，需要 1.4M 频谱， 现有技术需要 2.2M; 相比现有技术， 本发明此时节约了 0.8M频谱。 可见本发明实施例所提供的方法能够快速有效的节约交织冗余覆盖链的频谱 资源。
实施例三、 本发明本发明还提供另一种实现交织冗余覆盖的装置（如图 8 所示）， 用于执行前述各个实施例中的实现交织冗余覆盖的方法， 包括至少一 个处理器 801 (例如 CPU ), 至少一个网络接口 802或者其他通信接口， 存储 器 803 , 和至少一个通信总线 804, 用于实现这些装置之间的连接通信。 处理 器 801用于执行存储器 803 中存储的可执行模块， 例如计算机程序。 存储器 803可能包含高速随机存取存储器（ RAM: Random Access Memory ), 也可能 还包括非不稳定的存储器（ non-volatile memory ), 例如至少一个磁盘存储器。 通过至少一个网络接口 802 (可以是有线或者无线）实现该系统网关与至少一 个其他网元之间的通信连接， 可以使用互联网， 广域网， 本地网， 城域网等。
在一些实施方式中， 本发明所提供的装置中的存储器存储了程序 8031 , 程序可以被处理器执行， 这个程序包括： 根据预设的干扰距离间隔值， 确定 两个相隔小区之间的间隔距离， 所述两个间隔小区的间隔距离不小于所述干 扰距离间隔值时， 小区同邻频干扰小于预设的干扰阔值； 根据所述间隔距离 在所述两个间隔小区之间设置一个包括至少两个位置组的多站点共小区； 所 述多站点共小区和所述两个间隔小区中的两两相邻小区交织形成冗余覆盖 链， 而且多站点共小区内两两相邻的位置组交织实现链型冗余覆盖。
本申请实施例中的上述一个或多个技术方案， 至少具有如下的技术效果： 在本发明实施例中， 链型覆盖条件下 （铁路、 公路等场景）， 使用包括多 个位置组的多站点共小区技术来实现小区的交织冗余覆盖。 因为多站点共小 区可以扩大小区覆盖面积， 所以间隔一个多站点共小区的两个小区即可在满 足干扰条件的情况下设置为同频复用小区， 进而使得本发明实施例所提供的 装置和方法能够有效的节约无线频谱资源。
另外， 因为本发明所提供的方案中， 利用包括多个位置组的多站点共小 区代替现有技术中的普通小区， 从而使各小区 （即多站点共小区）之间的距 离增大。 因为小区间的同邻频干扰会受到两个小区之间的间隔距离影响， 所 以本发明的方案在增大小区间的间隔距离之后， 则可以将相隔一个小区的两 个小区设置相同或相邻的频点， 从而能够有效的增大链型冗余覆盖的频谱利 用率。
