对于 Logical 0&M, 其实质主要指无线配置功能, 为一组信令, 与逻辑资源的控制 相关, 该资源由 R C控制, 包括信道, 小区等, 而物理上由 Node B实现, Node B上的 0&M的程序将影响由 RNC控制的逻辑资源, 因此 Node B需要与 RNC就这些资源信息进 行信息交互, 该过程通过 lub接口进行。 Logical O&M在当前 UMTS系统中是 NBAP协议 信令的一部分。
目前,业界正在研究一种全新的演进网络架构以满足未来十年甚至更长时间内移动 网络的应用需求, 包括系统架构演进(SAE)和接入网的长期演进(LTE)。 网络演进的 目标是希望提供一种低时延、 高数据速率、 高系统容量和覆盖、 低成本、 完全基于 IP的 网络。 由于是一种全新的网络架构, 因此现有架构的所有节点、 功能和流程都将发生实 质性的变化。
演进移动网络中, 在无线资源管理(Radio Resource Management, RRM)中增加了 一个子功能项: 小区间无线资源管理 (inter Cell R M, 小区间 RRM、 ICR)。
小区间无线资源管理信息一般包括小区的负载信息、小区的干扰信息、频率或者载 波等, 简称为 ICR信息; 但 ICR信息不局限于以上信息, 只要对 ICR控制功能起作用的信 息, 都可以称为 ICR信息。
目前, LTE对 RRM信息、 ICR信息及 Logical 0&M提出了一些新的需求,如:在 RRM 集中控制的方式下需要考虑 Logical O&M的实现;
由于功率干扰以及小区负载不均等, 需要 inter-cell RRM; Inter-Cell RRM可能是 Logical O&M的一部分;以及由于用户的移动和数据速率改变的动态性质,动态 Inter-Cell RRM也是需要的等等情况。除了小区间干扰管理和小区间负载均衡管理以外,小区间切 换也属于 ICR的范畴。
对于 UMTS R99-Rel-g, OMC提供资源和参数信息给 R C, RNC再下发给 Node B, 资源和参数信息包括小区建立参数, 系统消息等, 这些全局的无线配置允许运营商提供 全局战略或者采用更实时的 RRM算法的策略,用来控制小区的容量和覆盖范围,调整网 络以适应网络流量需求。
现有的 UMTS系统中, RRM信息的提供者(Node B或者小区)是缺省报告对应 R C 的, 而对于演进移动网络, 与某个小区相关的 ICR信息, 很有可能要向多个 ICR信息保 存者报告, 如可能是一个或者多个 RRM服务器(RRM server), 或者是相邻的多个演进 的基站(eNodeB), 或者是其它拥有 Logical O&M功能的单独节点, 现有的 UMTS系统中 的流程和信令显然不能满足上述需求。
同时,在演进移动通信系统里,一个基站可能下辖一个小区,也可能下辖多个小区。 各个小区的频率带宽通常一样。 小区的载波频率资源可以按照使用用途不同, 分 为在小区中心使用的中心频率, 在小区边缘的边缘频率。这些频率一般可以划分成多个 子载波。 譬如一个 5M带宽的载波小区, 可以按照 15KHZ的带宽为一个子载波进行细分。 在资源调度器进行资源调度的时候, 一般按照子载波为单位。
因为相邻小区可以具有相同的子载波,所以, 当相邻小区相同的子载波使用在相邻 各自小区的中心区域的时候, 不会造成小区间干扰, 但是当相同的子载波使用在相邻小 区的边缘的时候, 这些使用相同边缘频率的小区之间就会造成干扰。 因此, 每个小区在 分配边缘频率的时候, 需要清楚相邻小区的频率使用情况 (过去, 现在, 将来), 至于 这个使用情况到底有多详细, 可能不同的算法有不同的要求。 因此, 需要提供一种方法 可以避免这种资源分配重复, 在小区边缘地区造成的干扰, 需要收集准确的 ICR信息。 发明内容

实施本发明的方式 本发明实施例提供了一种演进移动网络中 ICR信息测量报告的发送方法, 如图 9所 示, 其包括 4个流程:
( A) ICR信息测量初始化流程 ICR INFORMATION MEASUREMENT INITIATION;
(B) ICR信息测量报告流程 ICR INFORMATION MEASUREMENT REPORTING; ( C ) ICR信息测量终止流程 ICR INFROMATION MEASUREMENT
TERMINATION;
(D) ICR信息测量失败流程 ICR INFROMATION MEASUREMENT FAILURE; 上述 4个流程均是围绕 ICR信息收集发起者、信息提供者、 信息保存者以及 ICR功能 控制者中的部分或者全体展开的, 首先, 对后续提及的 ICR信息收集发起者、 信息提供 者、 信息保存者以及 ICR功能控制者的概念及其之间的关系做如下介绍:
针对 ICR信息, 演进移动网络提出了 ICR信息收集发起者、 信息提供者、 信息保存 者以及 ICR功能控制者的概念, 并在演进移动网络中上升为功能实体:
演进移动系统使用 OFDMA技术, 其为小区的载波或者子载波资源的动态调整提供 了技术基础, 如某个小区可以根据周围相邻小区的负载信息, 向周围的小区租借资源; 或者某个小区根据周围相邻小区的干扰信息, 调整自己的天线角度等; 这种功能, 具体 包括小区负载管理和小区干扰管理, 我们称之为 ICR控制功能, 而具备这种控制能力的 功能实体, 我们称之为 ICR功能控制者; 顾名思义, 能够发起 ICR信息收集的功能实体 称之为 ICR信息收集发起者;提供 ICR信息的功能实体或者节点,称之为 ICR信息提供者; 而负责保存 ICR信息的功能实体或者节点, 称之为 ICR信息保存者。
ICR信息收集发起者、 信息提供者、 信息保存者以及 ICR功能控制者功能实体关系 的确定, 也会因为演进移动网络中存在的其它功能实体的不同而有所区别, 具体如下: 图 4是演进移动网络中 OMC与 eNodeB连接示意图, 如图 4所示, 演进移动网络中, 无线资源管理服务器(RRM服务器, RRM SERVER)为一个可以选择的功能实体, 其 在图中以虚线框表示, 根据演进移动网络中 RRM SERVER的存在与否, 以及当 R M SERVER存在时执行功能的不同, ICR信息收集发起者、信息提供者、信息保存者以及 ICR 功能控制者功能实体具体如下:
( 1 ) 当演进移动网络中不存在 RRM SERVER时:
对于 ICR功能控制者, 存在三种 ICR方式:
( 1.1 ) 完全集中式 ICR, 即 ICR功能控制者集中在某个单独节点, 该单独节点可放 置于 eNodeB、 RRM SERVER或者网络中的其它位置,其集中执行 ICR控制功能, 进行小 区间负载管理和小区间干扰管理, 其它 eNodeB或者小区为被管理者;
( 1.2 )完全分布式 ICR, 即 ICR功能控制者分布在各个 eNodeB上, 各个 eNodeB都具 ICR控制功能, eNodeB可以与周围与之有 ICR关系的 eNodeB互为管理者和被管理者, 进 行小区间负载管理和小区间干扰管理;
( 1.3 ) 集中与分布并存式 ICR , 即 ICR功能控制者同时存在于某个单独节点和 eNodeB上, 即演进移动网络中部分与 ICR信息相关的功能实体由该单独节点控制, 部分 eNodeB控制其自身与 ICR信息相关的功能;
对于 ICR信息收集发起者, 其可能是 eNodeB, 或者是某个单独节点, 或者是 OMC; 对于 ICR信息提供者, 其是 eNodeB或者小区;
对于 ICR信息保存者, 其可能分布在各个 eNodeB, 或者汇总在 ICR功能控制者所在 的单独节点, 或者同时存在于 eNodeB和 ICR功能控制者所在的单独节点;
( 2 ) 当演进移动网络中存在 RRM SERVER, 但是 RRM SERVER只是存放 ICR信息 的数据库时- 对于 ICR功能控制者, 存在三种 ICR方式:
(2.1 ) 完全集中式 ICR, 即 ICR功能控制者集中在某个单独节点, 该单独节点可放 置于 eNodeB、 RRM SERVER或者网络中的其它位置, 其集中执行 ICR控制功能, 进行小 区间负载管理和小区间干扰管理, 其它 eNodeB或者小区为被管理者;
(2.2)完全分布式 ICR, 即 ICR功能控制者分布在各个 eNodeB上, 各个 eNodeB都具 ICR控制功能, eNodeB可以与周围与之有 ICR关系的 eNodeB互为管理者和被管理者, 进 行小区间负载管理和小区间干扰管理;
( 2.3 ) 集中与分布并存式 ICR, 即 ICR功能控制者同时存在于某个单独节点和 eNodeB上, 即演进移动网络中部分与 ICR信息相关的功能实体由该单独节点控制, 部分 eNodeB控制其自身与 ICR信息相关的功能;
对于 ICR信息收集发起者,其可能是 eNodeB,也可能是 RRM SERVER,或者是 OMC; 对于 ICR信息提供者, 其是 eNodeB或者小区, 或者当 ICR信息收集发起者非 RRM
SERVER时, ICR信息提供者可以是 RRM SERVER;
对于 ICR信息保存者, 其是 RRM SERVER, 或者同时 eNodeB也具有保存功能;
(3 ) 当演进移动网络中存在 RRM SERVER, RRM SERVER是存放 ICR信息的数据 库, 且 RRM SERVER具有 ICR控制功能时
对于 ICR功能控制者,.其是 RRM SERVER,或者允许部分 eNodeB具有功能控制者身 份, 与该 eNodeB相关的 ICR控制功能由该 eNodeB执行;
对于 ICR信息收集发起者, 其可能是 eNodeB, 或者可能是 RRM SERVER, 或者是 OMC;
对于 ICR信息提供者, 其是 eNodeB或者小区, 或者当 ICR信息收集发起者非 RRM SERVER时, ICR信息提供者可以是 RRM SERVER;
对于 ICR信息保存者, 其是 RRM SERVER, 或者可能是 eNodeB。
针对上述对 ICR功能控制者的介绍,无论是分布式或者集中式 ICR,对于某些 eNodeB 来说, 可以要求该些 eNodeB不具备 ICR功能控制者的身份, 那么该些 eNodeB将只是 ICR 功能控制中的被管理者, 被其他具有 ICR功能控制者身份的节点或者 eNodeB管理, 参与 小区间干扰管理和小区间负载管理等功能的实现。
明确了上述 ICR信息收集发起者、 信息提供者、 信息保存者以及 ICR功能控制者的 概念及确定了各功能实体, 则可以通过本发明设计的流程对本发明的方法做进一步说 明-
( A)ICR信息测量初始化流程 ICR INFORMATION MEASUREMENT INITIATION: 该流程用来实现 ICR信息收集发起者向 ICR信息提供者发起 ICR信息测量请求,从而 触发 ICR信息测量报告流程, 其流程图如图 5所示, 包括步骤:
步骤 ( 501 )、ICR信息收集发起者向 ICR信息提供者发送 ICR信息测量初始化请求 ICR INFORMATION MEASUREMENT INITIATION REQUEST消息;
步骤 ( 502 )、 ICR信息提供者接收到 ICR INFORMATION MEASUREMENT INITIATION REQUEST消息后, 根据消息中的参数执行测量或者直接提供 ICR信息, 并 向 ICR信息收集发起者回复 ICR信息测量响应 ICR INFORMATION MEASUREMENT RESPONSE消息。
ICR INFORMATION MEASUREMENT INITIATION REQUEST消息中包含两大消 息单元- Report characteristics (报告属性) 消息单元和 ICR information (ICR信息) 消息单 元: 其中
Report characteristics消息单元用来指示测量如何进行和上报:
当 Report characteristics设置为 "on demand" (按需) 时, ICR信息提供者一般立即 上报测量信息, 发起 ICR信息测量报告流程, 除非有其他情况;
当 Report characteristics设置为 "Periodic" (周期性)时, ICR信息提供者将按照该设 置的周期和频度上报测量信息, 发起 ICR信息测量报告流程, 除非有其他情况; 当 Report characteristics设置为 "by event" (事件) 时, ICR信息提供者将判断是否 发生该事件, 如果发生则发起 ICR信息测量报告流程, 除非有其他情况;
其中 event可能为以下几种情况:
当 event为 "up threshold mode" (超过某个门限) 时, ICR信息提供者判断要测量的 值(即为小区的负载信息或者小区的干扰信息)是否超过该门限, 并决定是否在一定迟 滞时间后发起 ICR信息测量报告流程, 除非有其他情况;
当 event为 "below threshold mode" (低于某个门限) 时, ICR信息提供者判断要测 量的值是否低于该门限, 并决定是否在一定迟滞时间后发起 ICR信息测量报告流程, 除 非有其他情况;
当 event为 "increase amount threshold mode" (在一定时间增长超过某个门限) 时, ICR信息提供者判断要测量的值是否在一定时间段内增加的数量超过该门限, 若超过则 决定是否在一定迟滞时间后发起 ICR信息测量报告流程, 除非有其他情况;
当 event为 " decrease amount threshold mode" (在一定时间减少超过某个门限) 时, ICR信息提供者判断要测量的值是否在一定时间段内减少的数量超过该门限, 若超过则 决定是否在一定迟滞时间后发起 ICR信息测量报告流程, 除非有其他情况。
而 ICR information消息单元中包含有:
"ICR collector ID" ( ICR信息保存者标识) 消息单元, 该消息单元是一个或者一组 消息单元, 该消息单元的内容包括 ICR信息保存者标识, 该标识可能只是一个 ID, 譬如 整数型数字或者其他数值类型, 用以标记 ICR信息保存者的身份, 通过该标识可以帮助 ICR信息提供者建立与 ICR信息保存者之间的关系, 找到 ICR信息保存者; 该标识也可能 是一个 IP地址或者其他地址格式信息;
"ICR initiator ID " ( ICR信息收集发起者标识)消息单元,该消息单元的内容是 ICR 信息收集发起者的标识, 用来表示谁发起的 ICR信息收集;
" ICR Controler ID " ( ICR功能控制者标识)消息单元, 该消息单元的内容是 ICR功 能控制者的标识, 用来表示是谁执行 ICR控制功能;
"ICR reporter ID" (ICR信息提供者标识)消息单元, 该消息单元的内容是 ICR信息 提供者的标识, 用来表示谁是 ICR信息提供者,
"ICR Test item" ( ICR信息测量内容) 消息单元, 该消息单元的内容是小区的负载 信息或者小区的干扰信息, 其用来告诉 ICR信息测量的实际执行者和提供者, 应该测量 并报告哪类 ICR信息。

threshold mod (B) ICR信息测量报告流程 ICR INFORMATION MEASUREMENT REPORTING: 该流程用来实现 ICR信息提供者将 ICR测量信息报告给相应的 ICR信息保存者, 其 流程图如图 6所示, 包括步骤:
步骤 (601 )、 ICR信息提供者向 ICR信息保存者发送 ICR信息测量报告 ICR INFORMATION MEASUREMENT REPORTING消息;
按照上述流程 (A) 中的触发方式, 所设定的触发方式的触发条件满足后, ICR信 息提供者发起 ICR信息测量报告流程, 将测量到的有关 ICR信息报告给 ICR信息保存者, 如上所述, 该 ICR信息保存者有可能是多个网络功能实体。
在上述的 ICR INFORMATION MEASUREMENT REPORTING消息中包含: 测量的 小区的负载信息、小区的干扰信息、频率或者载波等 ICR信息; ICR信息提供者标识; ICR 信息的釆集时间等内容。
其中, 如表 3所示, 测量的小区的负载信息、小区的干扰信息、频率或者载波等 ICR 信息包含但不限于以下内容:

( C ) ICR信息测量终止流程 ICR INFROMATION MEASUREMENT TERMINATION:
该流程用于 ICR信息收集发起者结束先前请求的 ICR信息测量初始化流程, ICR信息 提供者将停止针对上次测量请求的测量报告行为, 其流程图如图 7所示, 包括步骤: 步骤 (701 )、 ICR信息收集发起者向 ICR信息提供者发送 ICR信息测量终止 ICR INFROMATION MEASUREMENT TERMINATION消息;
步骤 (702 )、 ICR信息提供者收到 ICR INFROMATION MEASURE- MENT TERMINATION消息后, 停止 ICR信息测量报告。
(D) ICR信息测量失败流程 ICR INFROMATION MEASUREMENT FAILURE: 该流程用于 ICR信息提供者告知 ICR信息测量发起者先前 ICR INFORMATION MEASUREMENT INITIATION流程中请求的 ICR信息将不再测量报告, 其流程图如图 8 所示, 包括步骤- 步骤 (801 )、 ICR信息提供者向 ICR信息收集发起者发送 ICR信息测量失败 ICR INFROMATION MEASUREMENT FAILURE消息, 告知停止 ICR信息测量报告。
本发明实施例提出的上述流程及相应步骤, 在未来演进移动网络中可以单独成立, 也可以与目前 3GPP TS25.433协议中的 COMMON MEASUREMENT流程结合使用, 将本 发明实施例中的流程与现有流程合并, 通过增加或者修改 COMMON MEASUREMENT 流程中的消息的相关消息单元, 形成演进的 COMMON MEASUREMENT流程, 来达到 本发明实施例的目的; 另外, 本发明实施例还可以通过与 3GPP TS25.433协议中的 INFORMATION EXCHANGE流程合并,通过增加或者修改 INFORMATION EXCHANGE 流程中的消息的相关消息单元, 形成演进的 INFORMATION EXCHANGE流程, 来达到 本发明实施例的目的。
另外,本发明实施例还允许由 OMC的数据操作维护或数据配置触发 ICR信息提供者 上报 ICR信息的流程, 其中, OMC的数据操作维护或数据配置均包括: 事件触发设置, 如满足一定过载条件后触发 ICR信息提供者主动上报 ICR信息; ICR信息提供者主动周期 上报 ICR信息设置。
事件触发的处理方式是设置 ICR信息的门限, 该门限的设置是通过 OMC设定, 并由 eNodeB来执行, 门限包括负载门限或者干扰门限, 其中, 负载一般可以依靠 eNodeB的 发射总功率来衡量, 干扰可以传输误码率或者信干比来衡量, 但不局限于以上参数, 可 以是 eNodeB对其控制小区的总体负载情况和干扰情况的综合判断, ICR信息提供者检测 超过该门限后主动上报给其对应的 ICR信息保存者; 同时在 OMC上存在开关, 决定是否 启动或者关闭 ICR信息提供者主动上报 ICR信息。
ICR信息提供者主动周期上报 ICR信息设置为: 设置 ICR信息提供者向 ICR信息保存 者主动周期上报 ICR信息; 设置还包括: ICR信息保存者在收到第一次 ICR信息后主动回 复收到 ICR信息的响应; 在随后收到 ICR信息后按照一定的时间周期, 周期性的返回收 到 ICR信息的响应; 或者在超过一定时间未收到 ICR信息后主动向 ICR信息提供者反馈未 收到 ICR信息的响应。
对于上述没有使用 ICR INFORMATION MEASUREMENT INITIATION流程,而 ICR 信息提供者主动上报 ICR信息, 其上报的对象, 即 ICR信息保存者一般是指该 ICR信息提 供者 (eNodeB/小区) 的相邻 eNodeB/小区, 上报的 ICR信息可以只有负载信息, 也可以 只有干扰信息, 或者二者同时包括。
上述 OMC的数据操作维护或数据配置触发 ICR信息提供者上报 ICR信息的流程对应 的 ICR信息测量报告流程 ICR INFORMATION MEASUREMENT REPORTING^ ICR信息 测量失败流程 ICR INFROMATION MEASUREMENT FAILURE与前述本发明实施例提 及的流程完全一致, 不再重复; 因为上述为采用 OMC控制的启动或者关闭 ICR信息提供 者主动上报的流程, 对于 ICR信息测量终止流程 ICR INFROMATION MEASUREMENT TERMINATION在此流程中省略; 总体流程如下所述: (Al ) OMC的数据操作维护或数据配置触发 ICR信息提供者上报 ICR信息的流程; (B) ICR信息测量报告流程;
(C1 )采用 OMC控制的启动或者关闭 ICR信息提供者主动上报的流程;
(D) ICR信息测量失败流程。 本发明实施例提供一种 ICR信息收集方法, 在基站启动、 小区建立或小区重建后, 获取与该基站或小区相关联 ICR控制节点的 ICR信息。
如图 10所示, 具体的收集过程包括以下步骤- 步骤 (101 )、 基站 1向运行中的基站 2请求基站 2的资源使用情况;
步骤 (102)、 基站 2报告自己的资源使用情况;
步骤 (103)、 向运行中的基站 n请求基站 n的资源使用情况;
步骤 (104)、 基站 n报告自己的资源使用情况。
也即,当一个基站启动或该基站所管辖的小区建立或重建后,在可以进行服务前(主 要是指可以进行业务接入前, 也就是可以分配无线资源前), 主动向周围相关基站或小 区请求这些相关基站或小区 ICR信息。 ' 如图 11所示, 具体的收集过程包括以下步骤:
步骤 (111 )、 相关基站 2发现或者探测到基站 1启动;
步骤 (112)、 基站 2主动报告自己的资源使用情况;
步骤 (113 )、 相关基站 n发现或者探测到基站 1启动;
步骤 (114)、 基站 n主动报告自己的资源使用情况。
也即, 当一个基站启动、 小区建立或小区重建后, 在可以进行服务前(主要是指可 以进行业务接入前, 也就是可以分配无线资源前), 相关基站、 小区检测到基站启动、 小区建立或小区重建, 主动向该基站报告自己的 ICR信息。
如图 12所示, 具体的收集包括以下步骤:
步骤 (121 )、 向 RRM server获取相关 ICR信息;
步骤 (122)、 RRM SERVER报告有关基站 /小区 ICR信息。
也即, 当一个基站启动、小区建立或小区重建后, 向 RRM server获取相关 ICR信息, RRM SERVER报告有关基站 /小区 ICR信息。
在 LTE系统里, 因为基站之间有 X2接口,所以以上信息可以在 X2接口上传递。而基 站与 RRM SERVER之间有 X3接口, 所以以上信息可以在 X3接口上传递。 当基站启动或小区重建后, 从该基站的历史记录中获取该基站或小区相关联 ICR控 制节点的 ICR信息。
当启动起来的基站获得周围相关基站 /小区的 ICR信息,尤其是里面的子载波信息的 状态后, 就可以利用该信息来决定本小区的资源调度, 譬如哪些资源可以在什么时间段 分配或者使用在小区中心,哪些资源可以在什么时间段分配使用到小区边缘,也就是说, 可以进行 ICR, 包括 ICIC功能了。 基站可以根据从其他相关基站 /小区获得的 ICR信息, 分析综合后, 作为自己资源分配的一个起始点 (starting point)。
ICR信息里还可以包括各个基站的 RRM算法规则, 譬如切换门限参数, 切换算法参 数。 这些配置参数, 也可以通过基站中转到相关基站或者 ICR控制节点。 这些 ICR信息 可以根据 ICR的具体目的不同区分为干扰管理信息, 负载均衡管理信息或者小区间切换 信息, 不一定在一起传递或者同时传递。 分几次传递或者怎么传递, 不影响本发明。
在演进移动网络中, 通过实施本发明, 能够使 ICR信息收集发起者、 信息提供者、 信息保存者以及 ICR功能控制者之间互相沟通, 当存在至少一个 ICR信息保存者时, 能 够将 ICR信息同时上报给多个 ICR信息保存者, 实现演进移动网络中 ICR信息的测量上 报。
当基站 /小区获得相关 /相邻基站 /小区的信息后, 就可以对如何进行资源使用做到心 中有数, 尤其是在分配子载波的时候, 避免将其他小区用在小区边缘的子载波, 自己也 拿来使用在自己的小区边缘, 这样就可以保证在小区的边缘, 相邻小区使用的子载波不 一样, 避免干扰冲突。
基站 /小区通过 ICR信息收集方法, 获得其他基站 /小区的切换算法参数, 可以解决 不同厂家基站 /小区切换参数设置不同, 如何协调的问题。
以上所述, 仅为本发明较佳的具体实施方式, 但本发明的保护范围并不局限于此, 任何熟悉本技术领域的技术人员在本发明揭露的技术范围内, 可轻易想到的变化或替 换, 包括无论未来演进移动网络中对 ICR信息测量和报告的流程的命名如何, 以及在涉 及 ICR信息测量和报告的流程中添加其他测量信息或者与其他测量控制流程合并, 都应 涵盖在本发明的保护范围之内。
