本发明提供的实现物理小区标识自动配置的方法, 其核心要点是, 在对 总数为 N的物理小区标识 PhyCellld进行自动配置前, 通过网管系统依序将 PhyCellld分为两组, 第一组中 PhyCellld个数为 A; 第二组中 PhyCellld个数 为 (N-A ) ; 系统的每一个 eNodeB在进行 PhyCellld自动配置时, 分散地从 第一组 A个 PhyCellld中选取一个或连续多个 PhyCellld配置使用;当 eNodeB 检测到本区使用的 PhyCellld资源与邻区使用的 PhyCellld资源可能会发生冲 突时, 从第二组未使用的 PhyCellld中再选取一个或连续多个 PhyCellld资源 替换与邻区冲突的 PhyCellld资源; 当 eNodeB发现本小区已使用的 PhyCellld 资源不足时, 则在第二组未使用的 PhyCellld 中再选择一个或连续多个 PhyCellld资源补充本小区不足的 PhyCellld资源。 The core point of the method for realizing the automatic configuration of the physical cell identifier provided by the present invention is that the PhyCellld is sequentially divided into two groups by the network management system before the automatic configuration of the physical cell identifier PhyCellld of the total number N, and the first group is PhyCellld. The number of PhyCellld in the second group is (NA); each eNodeB of the system randomly selects one or a plurality of PhyCellld configurations from the first group of PhyCelllds when performing PhyCellld autoconfiguration; The eNodeB detects that the PhyCellld resource used in this area and the PhyCellld resource used in the neighboring area may be rushed. When the eNodeB finds that the PhyCellld resource used by the cell is insufficient, the eNodeB does not use the PhyCellld resource that is in use in the second group. In the PhyCellld, one or more consecutive PhyCellld resources are selected to supplement the insufficient PhyCellld resources of the cell.
以下结合附图和具体实施例, 将本发明的上述技术方案进行更详细地解 释和说明。  The above technical solutions of the present invention will be explained and explained in more detail below with reference to the accompanying drawings and specific embodiments.
E-UTRA 系统 eNodeB群组连接如图 2所示, 其中 eNode 的全局编号 GlobaleNodeBID分别为 1 , 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16。 The E-UTRA system eNodeB group connection is shown in Figure 2, where the eNode's global number GlobaleNodeBID is 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, respectively. 15, 16.
本发明提供的实现物理小区标识自动配置的方法, 在对系统总数为 N The method for realizing physical cell identifier automatic configuration provided by the present invention, the total number of pairs of systems is N
(N=504)的物理小区标识 PhyCellld进行自动配置前, 首先通过网管系统对 N个 PhyCellld进行分组: (N=504) physical cell identifier Before PhyCellld performs automatic configuration, firstly, N PhyCelllds are grouped through the network management system:
将 PhyCellld按序分为两大组, 第一大组 PhyCellld个数为 A , 第二大组 PhyCellld个数为 504-A。  The PhyCellld is divided into two groups in order. The number of PhyCellld in the first group is A, and the number of PhyCellld in the second group is 504-A.
将第一大组再依序分为 M小组, 每小组 PhyCellld个数为 G=A/M, 对每 个小组进行编号为 0, 1, 2, 3..... M-1, 该第一大组在系统进行 PhyCellld初 始自配置时使用。  The first large group is further divided into M groups. The number of PhyCellld in each group is G=A/M, and each group is numbered 0, 1, 2, 3..... M-1, the first A large group is used when the system performs PhyCellld initial self-configuration.
将第二大组再依序分为 0+P+Q+R+S+T+ .....小组, 每类小组 PhyCellld资 源 的 个 数 分 别 为 o,p,q,r,s,t ...... , 且 满 足如 下 约 束条件 : o*0+p*P+q*Q+r*R+s*S+t*T ..... =504-A, o<p<q<r<s<t ..... , 0>P>Q>R> The second largest group is further divided into 0+P+Q+R+S+T+ ..... groups, and the number of PhyCellld resources in each group is o, p, q, r, s, t. ..... , and the following constraints are met: o*0+p*P+q*Q+r*R+s*S+t*T ..... =504-A, o<p<q <r<s<t ..... , 0>P>Q>R>
S > T ......,该第二大组在系统发生邻区 PhyCellld资源冲突或资源不足时使用。 S > T ......, the second largest group is used when the system has a neighboring PhyCellld resource conflict or insufficient resources.
在 eNodeB进行 PhyCellld资源自配置时, 从 0 , 1 , 2, 3...... M- 1小组中 选取一个小组的 PhyCellld使用 , 选取的小组组号通过将 GlobaleNodeBID对 When the PhyCellld resource self-configuration is performed on the eNodeB, select a group of PhyCellld from the 0, 1, 2, 3... M-1 group, and select the group group number by using the GlobaleNodeBID pair.
M求模得到。 M is obtained by modulo.
在 eNodeB检测到使用的 PhyCellld资源小组组号与相邻的 eNodeB使用 的 PhyCellld资源小组组号相同, 即使用的 PhyCellld资源有可能发生冲突, 则从第二大组中重新选取一小组 PhyCellld 资源替换与相邻 eNodeB相同的 PhyCellld资源小组。 或者, 在 eNodeB发现本区已使用的 PhyCellld组资源不足, 则在第二大 组中再选择一组数量合适的 PhyCellld资源进行补充。 The PhyCellld resource group group number used by the eNodeB is the same as the PhyCellld resource group group number used by the adjacent eNodeB, that is, the used PhyCellld resources may collide, and a group of PhyCellld resource replacements are reselected from the second largest group. The same PhyCellld resource group as the adjacent eNodeB. Alternatively, if the eNodeB finds that the PhyCellld group resources used in the area are insufficient, then select a suitable number of PhyCellld resources for supplementation in the second largest group.
以下为了进一步地理解本发明的上述方法, 例举一个应用实例。  In order to further understand the above method of the present invention, an application example is exemplified below.
譬如通过网管系统将 PhyCellld按序分为两大组, 第一大组 PhyCellld个 数为 360, 第二大组 PhyCellld个数 =504-360=144。  For example, PhyCellld is divided into two groups in sequence through the network management system. The first group of PhyCellld is 360, and the second largest group is PhyCellld = 504-360=144.
将第一大组分为 6小组,每小组 PhyCellld个数为 360/6=60,对每个小组 进行编号为 0, 1 , 2, 3 , 4, 5。  The first major component is 6 groups, each group has a PhyCellld number of 360/6=60, and each group is numbered 0, 1, 2, 3, 4, 5.
将第二大组分为 4+2个小组, 组号分别为 6, 7, 8, 9, 10, 11 ; 其中, 6、 7、 8、 9小组 PhyCellld资源的个数为 6, 10、 11组的个数为 60, 且满足 如下约束条件: 6*4+60*2=144。  The second largest component is 4+2 groups, and the group numbers are 6, 7, 8, 9, 10, 11 respectively; among them, the number of PhyCellld resources of groups 6, 7, 8, and 9 is 6, 10, 11 The number of groups is 60, and the following constraints are met: 6*4+60*2=144.
各个 eNodeB 上电从网管系统获取到 PhyCellld分组信息, 即系统的 PhyCellld分为 0, 1 , 2, 3 , 4, 5组; 在进行 PhyCellld初始自配置时, 从 0, 1 , 2, 3 , 4, 5组中选取一组 PhyCellld使用, 组号通过 GlobaleNodeBID对 6 求模得到, 如图 3所示。  Each eNodeB is powered on to obtain PhyCellld group information from the network management system, that is, the system's PhyCellld is divided into 0, 1, 2, 3, 4, and 5 groups; when performing PhyCellld initial self-configuration, from 0, 1, 2, 3, 4 In the 5 groups, a group of PhyCellld is selected, and the group number is obtained by GlobaleNodeBID, as shown in FIG.
实际上,上述将第一组 PhyCellld资源等分为 M小组,目的是使 PhyCellld 资源平均分配到各 eNodeB,但实际上 M小组的 PhyCellld资源也可以不相等, 譬如 GlobaleNodeBID 为 1 的 eNodeB 选取第 1~20 个 PhyCellld , GlobaleNodeBID为 2的 eNodeB选取第 21~30个 PhyCellld, …。 另夕卜, 第一 大组的 PhyCellld资源也可以不再进行分小组, eNodeB直接从第一大组中选 取任意的 PhyCellld资源作为初始分配,然后根据不同的分配算法和冲突解决 方法从第二大组选取 PhyCellld资源进行替换;或者在没有产生冲突的情况下 继续使用初始分配的 PhyCellld资源, 最终不需要从第二大组选取 PhyCellld 资源进行替换。  In fact, the first group of PhyCellld resources are equally divided into M groups, so that the PhyCellld resources are evenly distributed to each eNodeB, but in fact, the PhyCellld resources of the M group may not be equal, for example, the eNodeB with the GlobaleNodeBID of 1 selects the first one~ 20 PhyCellld, GlobaleNodeBID 2 eNodeB selects 21~30 PhyCellld, .... In addition, the first large group of PhyCellld resources may not be sub-group, and the eNodeB directly selects any PhyCellld resource from the first large group as the initial allocation, and then proceeds from the second largest according to different allocation algorithms and conflict resolution methods. The group selects the PhyCellld resource for replacement; or continues to use the initially allocated PhyCellld resource without conflict, and finally does not need to select the PhyCellld resource for replacement from the second largest group.
eNodeB 7在进行 PhyCellld自配置时发现已经使用的组 1 PhyCellld资源 不足, 则在 6, 7, 8, 9, 10, 11组中再选择数量合适的组 6 PhyCellld资源 使用, 如图 4所示。  When the PhyCellld self-configuration is performed, the eNodeB 7 finds that the used group 1 PhyCellld resources are insufficient. In the 6, 7, 8, 9, 10, and 11 groups, select the appropriate number of groups. 6 PhyCellld resources are used, as shown in Figure 4.
或者, 当 eNodeB 10检测到相邻 eNodeB 4使用了 PhyCellld组号 4, 或 者, eNodeB 11检测到相邻 eNodeB 4使用了 PhyCellld组号 5, 如图 4所示, 则 eNodeB 10重新从 6, 7, 8, 9, 10, 11组中重新选取组号为 10的一组 PhyCellld 使用, 或者, eNodeB 11重新从 6, 7, 8, 9, 10, 11组中重新选取组号为 11 的一组 PhyCellld使用, 如图 5所示。 Alternatively, when the eNodeB 10 detects that the neighboring eNodeB 4 uses the PhyCellld group number 4, or the eNodeB 11 detects that the neighboring eNodeB 4 uses the PhyCellld group number 5, as shown in FIG. Then eNodeB 10 re-selects a group of PhyCellld with group number 10 from 6, 7, 8, 9, 10, 11 groups, or eNodeB 11 re-relies from groups 6, 7, 8, 9, 10, 11 Select a group of PhyCellld with group number 11 as shown in Figure 5.
注: eNodeB检测相邻 eNodeB物理小区标识资源组是否相同的方法与本 发明无关, 故在此不进行详细描述。  Note: The method for the eNodeB to detect whether the neighboring eNodeB physical cell identity resource groups are the same is not related to the present invention, and therefore will not be described in detail herein.
