Description

技术领域 Technical field
本发明涉及通信技术领域, 尤其涉及一种异频邻区确定方法、 装置及系 统、 测量方法及装置。 背景技术  The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a system, a measurement method and a device for determining an inter-frequency neighboring cell. Background technique
在通用移动通讯系统 (英文: Universal Mobile Telecommunication System, 缩写: UMTS ) 中, 多频段多载波组网的场景非常常见, 因此, 对 异频邻区的关系进行优化的迫切程度日益体现。  In the Universal Mobile Telecommunication System (UMTS), multi-band multi-carrier networking scenarios are very common. Therefore, the urgency to optimize the relationship between different-frequency neighbors is increasingly reflected.
自动邻区关系 (英文: Auto Neighbor Relation, 缩写: ANR) 特性可以 自动优化邻区关系, 是最重要的自组织网络(英文: Self-Organized Network, 缩写: SON) 特性之一。 在 UMTS异频 ANR中, 需要对可能发生漏配的异频 邻区进行测量, 根据测量结果判断某个小区是否真正的漏配邻区。  The Auto Neighbor Relation (ANR) feature automatically optimizes the neighborhood relationship and is one of the most important features of the Self-Organized Network (English: Self-Organized Network, SON). In the UMTS inter-frequency ANR, it is necessary to measure the inter-frequency neighboring area where the missed allocation may occur, and determine whether a cell actually misses the neighboring area according to the measurement result.
但是在 3GPP Release 10之前的协议中, 不支持漏配异频邻区的检测, 只 能将可能漏配邻区的频点和扰码携带在正常切换的测量控制中下发,对已配 异频邻区进行测量。 如果已配邻区满 32个, 则无法下发漏配邻区的频点和扰 码, 另一方面漏配的频点和扰码不能离散下发, 只能设置检测范围的开始和 结束范围, 检测时间长, 检测效率低, 且 UMTS异频邻区漏配可能导致掉话 和异频切换失败。 发明内容  However, in the previous protocol of 3GPP Release 10, the detection of the mismatched inter-frequency neighboring cell is not supported. Only the frequency and scrambling code of the neighboring cell may be carried in the measurement control of the normal handover. The frequency neighboring area is measured. If the number of neighboring cells is 32, the frequency and scrambling code of the neighboring zone cannot be sent. On the other hand, the frequency and scrambling code of the missing zone cannot be sent out discretely. Only the start and end ranges of the detection range can be set. The detection time is long, the detection efficiency is low, and the mismatch of the UMTS inter-frequency neighboring area may cause the call drop and the inter-frequency handover failure. Summary of the invention

实施例 1  Example 1
图 1示出根据本发明一实施例的异频邻区确定方法的流程图。 如图 1所 示, 该方法主要包括:  FIG. 1 is a flow chart showing a method for determining an inter-frequency neighboring cell according to an embodiment of the present invention. As shown in Figure 1, the method mainly includes:
步骤 110、在待优化小区的 UE的 RAB释放之后, RRC连接释放之前, RNC 向该 UE下发异频测量控制信号, 该异频测量控制信号中携带至少一个该待 优化小区的潜在邻区;  Step 110: After the RAB release of the UE of the cell to be optimized, before the RRC connection is released, the RNC sends an inter-frequency measurement control signal to the UE, where the inter-frequency measurement control signal carries at least one potential neighboring cell of the to-be-optimized cell;
步骤 120、 RNC接收该 UE返回的携带有潜在邻区的异频测量结果的异频 测量报告;  Step 120: The RNC receives an inter-frequency measurement report that is returned by the UE and carries the inter-frequency measurement result of the potential neighboring cell.
步骤 130、 RNC根据异频测量报告为该待优化小区确定异频邻区。  Step 130: The RNC determines an inter-frequency neighboring cell for the to-be-optimized cell according to the inter-frequency measurement report.
本实施例在 UE的 RAB释放完成之后和 RRC连接释放之前进行, 也就是 说, RAB释放完成之后并不立即执行 RRC释放, 二者之间设定有 20s-60s的时 间段, 在该时间段内执行上述异频邻区确定方法, 对 UE的正常切换业务没 有任何影响, 避免了 UMTS异频邻区漏配导致的掉话和异频切换失败, 降低 了掉话率并提高了异频切换成功率。 This embodiment is performed after the completion of the RAB release of the UE and before the release of the RRC connection, that is, the RRC release is not performed immediately after the RAB release is completed, and the time between the two is set to be 20s-60s. In the inter-segment, the method for determining the inter-frequency neighboring cell is performed in the time period, which has no effect on the normal handover service of the UE, and avoids the call drop and the inter-frequency handover failure caused by the mismatch of the UMTS inter-frequency neighboring cell, and reduces the dropped call. Rate and improve the success rate of inter-frequency switching.
实施例 2  Example 2
图 2示出根据本发明另一实施例的异频邻区确定方法及测量方法的流程 图。 如图 2所示, 该方法包括:  FIG. 2 is a flow chart showing a method and a method for determining an inter-frequency neighboring cell according to another embodiment of the present invention. As shown in Figure 2, the method includes:
步骤 S210、 RNC为每个待优化小区确定需要检测的潜在邻区列表。  Step S210: The RNC determines, for each cell to be optimized, a list of potential neighbors that need to be detected.
具体而言, 在 UE的 RAB释放完成之前, 或特性启动之后, 立即计算每 个待优化的 UMTS小区的潜在邻区。 潜在邻区是指在一定距离范围内, 比如 三阶邻区范围内有可能发生切换的未配置小区, 也即漏配邻区。 该潜在邻区 可以根据待优化小区的工程参数和 RNC配置数据计算得到。如果某个待优化 小区没有工程参数, 那么可以只采用 RNC配置数据计算潜在邻区。  Specifically, before the UE's RAB release is completed, or after the feature is started, the potential neighbor of each UMTS cell to be optimized is immediately calculated. A potential neighboring area refers to an unconfigured cell that may be switched within a certain distance, for example, a third-order neighboring cell, that is, a missing neighboring cell. The potential neighboring area can be calculated according to the engineering parameters of the cell to be optimized and the RNC configuration data. If there is no engineering parameter for a cell to be optimized, then the potential neighbors can be calculated using only the RNC configuration data.
如图 3所示, 该步骤 S210具体包括:  As shown in FIG. 3, the step S210 specifically includes:
步骤 S2101、 RNC根据待优化小区的工程参数计算第一候选潜在邻区。 本步骤中,利用工程参数中的经纬度信息,以待优化小区的位置为中心, 查找半径为预设的漏配距离门限 (英文: Distance Threshold)范围内的所有小 区, 并将查找到的小区记为该待优化小区的第一候选潜在邻区, 集合 {A} ; 如果某个待优化小区没有工程参数, 则对应于待优化小区的集合 {A}为空。  Step S2101: The RNC calculates a first candidate potential neighboring area according to an engineering parameter of the to-be-optimized cell. In this step, using the latitude and longitude information in the engineering parameters, centering on the location of the cell to be optimized, searching for all cells within the range of the preset distance threshold (English: Distance Threshold), and searching for the found cell For the first candidate potential neighboring cell of the to-be-optimized cell, the set {A}; if a cell to be optimized has no engineering parameters, the set {A} corresponding to the cell to be optimized is empty.
对于该漏配距离门限, 本实施例中根据基站所位于的环境来确定。 比如 基站位于城区时基站之间的距离较近, 这样漏配距离门限可以设为 1公里, 基站位于郊区时相距较远, 相应的漏配距离门限可以设置的大一些, 例如 2 或 3公里。  For the mismatch distance threshold, in this embodiment, it is determined according to the environment in which the base station is located. For example, when the base station is located in the urban area, the distance between the base stations is relatively close, so that the missing distance threshold can be set to 1 km, and the base stations are located far apart in the suburb, and the corresponding missing distance threshold can be set larger, for example, 2 or 3 kilometers.
步骤 S2102、 RNC根据待优化小区的 RNC配置数据计算第二候选潜在邻 区。  Step S2102: The RNC calculates a second candidate potential neighbor according to the RNC configuration data of the to-be-optimized cell.
具体地, 利用 RNC配置数据中的邻区信息, 查找每个待优化小区的二阶 邻区和三阶邻区, 并将查找到的邻区记为该待优化小区的第二候选潜在邻 区, 集合 {B} ; Specifically, using the neighbor information in the RNC configuration data, searching for the second order of each cell to be optimized a neighboring cell and a third-order neighboring cell, and the discovered neighboring cell is recorded as a second candidate potential neighboring cell of the to-be-optimized cell, and the set {B};
本实施例中, 对于 UMTS异频邻区, 二阶邻区和三阶邻区的查找算法包 括:  In this embodiment, for the UMTS inter-frequency neighboring cell, the second-order neighboring cell and the third-order neighboring cell search algorithm include:
一阶邻区为待优化小区的异频邻区;  The first-order neighboring cell is an inter-frequency neighboring cell of the cell to be optimized;
二阶邻区为待优化小区的同频邻区的异频邻区;  The second-order neighboring cell is an inter-frequency neighboring cell of the same-frequency neighboring cell of the to-be-optimized cell;
三阶邻区为待优化小区的同频邻区的同频邻区的异频邻区。  The third-order neighboring cell is an inter-frequency neighboring cell of the same-frequency neighboring cell of the same-frequency neighboring cell of the to-be-optimized cell.
一阶邻区、 二阶邻区、 及三阶邻区的集合构成集合 {B}。  The set of first-order neighboring regions, second-order neighboring regions, and third-order neighboring regions constitutes a set {B}.
步骤 S2103、 将集合 {A}和集合 {B}进行合并。  Step S2103: Combine the collection {A} and the collection {B}.
将第一候选潜在邻区集合 {A}和第二候选潜在邻区集合 {B}进行合并, 即取并集, 记为集合 {C}。  The first candidate potential neighbor set {A} and the second candidate potential neighbor set {B} are merged, that is, the union is taken as the set {C}.
步骤 S2104、 RNC对合并后的候选潜在邻区集合进行筛选生成潜在邻区 列表。  Step S2104: The RNC filters the merged candidate potential neighbor set to generate a potential neighbor list.
根据 RNC配置信息, 从集合 {C}中筛除已配邻区, 剩下的邻区组成了该 待优化小区的潜在邻区列表。  According to the RNC configuration information, the allocated neighboring cells are filtered out from the set {C}, and the remaining neighboring cells constitute a list of potential neighboring cells of the to-be-optimized cell.
步骤 220、在 UE的 RAB释放完成后, RNC向待优化小区内的 UE下发异频 测量控制信号, 该异频测量控制信号至少携带有对应于 UE的潜在邻区所需 要测量的扰码范围和频点范围;  Step 220: After the RAB release of the UE is completed, the RNC sends an inter-frequency measurement control signal to the UE in the cell to be optimized, where the inter-frequency measurement control signal carries at least a scrambling code range that needs to be measured corresponding to the potential neighboring area of the UE. And frequency range;
本实施例中, 与现有技术中在 UE的 RAB释放之后立即释放 RRC连接所 不同的是, 在 UE的 RAB释放业务, 包括电路交换(英文: Circuit Switch, 缩 写: CS )域 RAB释放或者分组交换(英文: Packet Switch,缩写: PS )域 RAB 释放完成之后, RNC并不立即释放 RRC连接, 而是延长一时间段再释放 UE 的 RRC连接, 该延长的时间范围可以为 20s-60s, 本实施例中优选为 30秒。 本 发明提供的方法即在该延长的时段内执行。  In this embodiment, the RRC connection is released immediately after the RAB of the UE is released in the prior art, and the RAB release service in the UE includes circuit switching (English: Circuit Switch, abbreviation: CS) domain RAB release or grouping. After the RAB release is complete, the RNC does not release the RRC connection immediately. Instead, it releases the RRC connection of the UE for a period of time. The extended time range can be 20s-60s. In the embodiment, it is preferably 30 seconds. The method provided by the present invention is performed during the extended period of time.
RNC将扰码范围和频点范围携带在异频测量控制信号中, 使得 UE能够 根据该扰码范围和频点范围对相应的潜在邻区进行专有测量。每条异频测量 控制信号最多下发 32个潜在邻区的扰码和频点。此外异频测量控制信号中还 可以携带每码片能量与噪声功率密度噪声比 Ec/NO及 RSCP。携带的潜在邻区 从潜在邻区列表中选取, 如图 4所示, 具体而言, 为每个 UE从潜在邻区列表 中挑选潜在邻区的方法为: The RNC carries the scrambling code range and the frequency range in the inter-frequency measurement control signal, so that the UE can Proprietary measurements are made on the corresponding potential neighbors based on the scrambling code range and frequency range. Each of the inter-frequency measurement control signals delivers a maximum of 32 potential neighboring regions' scrambling codes and frequency points. In addition, the inter-frequency measurement control signal can also carry the energy per-chip energy to noise power density noise ratio Ec/NO and RSCP. The potential neighboring area carried is selected from the list of potential neighboring areas, as shown in FIG. 4, specifically, the method for selecting a potential neighboring area from the list of potential neighboring areas for each UE is:
步骤 2201、 RNC判断潜在邻区列表中的潜在邻区是否不大于 32个, 是则 执行步骤 2206; 否则 RNC根据邻区优先级、 各 UE支持的频段对潜在邻区列 表中的所有潜在邻区进行轮询,为每个 UE选择出供 UE进行测量的潜在邻区, 具体执行步骤 2202;  Step 2201: The RNC determines whether the potential neighboring cell in the potential neighboring cell list is not greater than 32. If yes, step 2206 is performed; otherwise, the RNC compares all potential neighboring cells in the potential neighboring cell list according to the neighboring cell priority and the frequency band supported by each UE. Performing polling, selecting a potential neighboring area for the UE to perform measurement for each UE, and performing step 2202;
步骤 2206、 RNC将潜在邻区列表中的所有潜在邻区确定为各 UE的潜在 邻区;  Step 2206: The RNC determines all potential neighboring areas in the potential neighbor list as potential neighboring areas of each UE.
步骤 2202、 RNC根据邻区优先级对潜在邻区列表中的所有潜在邻区进行 排序; 邻区优先级指源小区 (即待优化小区) 与潜在邻区之间距离的远近顺 序, 距离越近, 优先级越高, 排序越靠前, 也可以称为邻区配置顺序。  Step 2202: The RNC sorts all potential neighboring cells in the potential neighboring cell list according to the neighboring cell priority. The neighboring cell priority refers to the distance between the source cell (that is, the cell to be optimized) and the potential neighboring cell. The closer the distance is, the closer the distance is. The higher the priority, the higher the sorting, and it can also be called the neighboring configuration order.
步骤 2203、 RNC根据各 UE支持的频段对排序后的上述潜在邻区进行筛 选, 将不支持该 UE的频段的潜在邻区筛除, 得到对应于每个 UE的潜在邻区, 如果潜在邻区的个数多于 32个, 则由于每条异频测量控制信号中最多携带 32 个, 因此对该 UE下发的异频测量控制信号会不止一条。  Step 2203: The RNC filters the sorted potential neighboring areas according to the frequency bands supported by the UE, and screens the potential neighboring areas of the frequency band that does not support the UE, and obtains a potential neighboring area corresponding to each UE, if the potential neighboring area The number of the inter-frequency measurement control signals sent by the UE is more than one, because there are more than 32 inter-frequency measurement control signals.
进一步地, 在 UE的跨 PLMN切换开关关闭的情况下, 还可以包括: 步骤 2204、RNC还可以按照该 UE支持的 PLMN对频段筛选后的上述潜在 邻区进行进一步筛选, 将不支持该 UE的 PLMN的潜在邻区筛除; 如果 UE的 跨 PLMN切换开关打开, 则不执行此步骤。  Further, in a case that the cross-PLMN switch of the UE is off, the method further includes: Step 2204: The RNC may perform further screening on the potential neighboring area after the frequency band screening according to the PLMN supported by the UE, and the UE is not supported. The potential neighbor of the PLMN is screened out; if the UE's cross-PLMN switch is turned on, this step is not performed.
进一步地, 当 UE位于 UMTS异频邻区时, 还可以包括:  Further, when the UE is located in the UMTS inter-frequency neighboring cell, the method may further include:
步骤 2205、 RNC还根据潜在邻区的覆盖优先级进行筛选, 筛除覆盖优先 级为 0的潜在邻区。 该覆盖优先级为预先设置,例如有些频点的优先级比其它频点的优先级 高, 需要先给 UE发送优先级较高的频点进行测量, 这样的小区的覆盖优先 级就比较高。 覆盖优先级越高的异频邻区越容易作为覆盖测量对象下发且 UE越容易切换到该小区。 优先级为 0代表不下发, 覆盖优先级为 1的小区被 下发给 UE的优先级高于优先级为 2的小区, 更容易作为覆盖测量对象下发, 且 UE更容易切换到覆盖优先级为 1的小区。而且, 下发测量控制时,如果多个 异频邻区是同一个频点, 则这些异频邻区的优先级均按其中的最高优先级处 理, 当异频邻区数量大于 32个时, 覆盖优先级低的邻区不会在测量控制列表 里下发。 Step 2205: The RNC also filters according to the coverage priority of the potential neighboring area, and filters out the potential neighboring area with the priority of 0. The coverage priority is set in advance. For example, the priority of some frequency points is higher than the priority of other frequency points. The UE needs to send a higher priority frequency point for measurement, and the coverage priority of such a cell is relatively high. The higher the priority of the inter-frequency neighboring cell is, the easier it is to be delivered as the coverage measurement object and the easier it is for the UE to switch to the cell. If the priority is 0, the cell with the priority of 1 is sent to the UE with a higher priority than the cell with the priority of 2. The cell is more easily delivered as the coverage measurement object, and the UE is more likely to switch to the coverage priority. A cell of 1. Moreover, when the measurement control is performed, if the multiple inter-frequency neighboring cells are the same frequency point, the priorities of the inter-frequency neighboring cells are processed according to the highest priority among them, and when the number of inter-frequency neighboring cells is greater than 32, Neighbors with low priority overrides will not be delivered in the measurement control list.
上述四个条件中, 邻区优先级所基于的距离信息、 UE所支持的频段在 UE请求建立 RRC连接的时候就会携带, RNC通过 RRC请求中携带的信息获 得。 距离信息由 UE根据工程参数信息中的经纬度信息计算得到, 移动国家 号码 (英文: Mobile Country Code, 缩写: MCC) +移动网络号码 (英文: Mobile Network Code, 缩写: MNC), 即 PLMN, 根据工程参数和 RNC的配 置参数可以得到。根据上述四个条件对潜在邻区列表中的潜在邻区进行筛选 的顺序并不限于上述顺序。  In the above four conditions, the distance information based on the priority of the neighboring cell and the frequency band supported by the UE are carried when the UE requests to establish an RRC connection, and the RNC obtains the information carried in the RRC request. The distance information is calculated by the UE according to the latitude and longitude information in the engineering parameter information, the mobile country number (English: Mobile Country Code, abbreviation: MCC) + mobile network number (English: Mobile Network Code, abbreviation: MNC), ie PLMN, according to the project Parameters and RNC configuration parameters are available. The order in which the potential neighboring cells in the list of potential neighboring cells are filtered according to the above four conditions is not limited to the above order.
由于各 UE的频点能力不同、支持的频段不同或者所属 PLMN有差异, 因 此 RNC为每个 UE选择的潜在邻区不一定完全相同。  Since each UE has different frequency point capabilities, different supported frequency bands, or different PLMNs, the potential neighbors selected by the RNC for each UE may not be identical.
此外, 当为某个 UE选择出待测量的潜在邻区后需要记录当前选择到的 次序, 下一次选择的时候直接从该次序后面的一个潜在邻区开始轮询。 当剩 余的邻区不足 32个, 再从头开始轮询, 即循环下发异频测量控制信号。  In addition, when a potential neighbor to be measured is selected for a certain UE, the currently selected order needs to be recorded, and the next selection is directly polled from a potential neighbor after the sequence. When there are less than 32 neighbors, the polling is started from the beginning, that is, the inter-frequency measurement control signal is issued cyclically.
步骤 230、 UE根据接收到的异频测量控制信号, 对该异频测量控制信号 中的潜在邻区进行异频测量,并将异频测量结果携带在异频测量报告(英文: Measurement Report ) 中返回给 RNC。  Step 230: The UE performs inter-frequency measurement on the potential neighboring area in the inter-frequency measurement control signal according to the received inter-frequency measurement control signal, and carries the inter-frequency measurement result in the inter-frequency measurement report (English: Measurement Report) Return to the RNC.
具体而言, UE接收到异频测量控制信号之后, 对各潜在邻区的扰码、 频点、 Ec/N0以及 RSCP进行检测。 Specifically, after the UE receives the inter-frequency measurement control signal, the scrambling code for each potential neighboring area, Frequency, Ec/N0 and RSCP are detected.
此外, 在步骤 230之前或之后或同步地, 本方法还可以包括:  Furthermore, before or after step 230 or synchronously, the method may further comprise:
步骤 240、 在 RNC日志中记录潜在邻区列表中每个潜在邻区被下发的次 数。  Step 240: Record, in the RNC log, the number of times each potential neighbor in the potential neighbor list is delivered.
具体地, RNC在 RNC日志中增加一个潜在邻区下发的信息块, 对每个潜 在邻区被下发的次数进行统计。  Specifically, the RNC adds a block of information sent by the potential neighboring area to the RNC log, and counts the number of times that each potential neighboring area is delivered.
步骤 250、 RNC根据接收到的异频测量报告为每个待优化小区选择异频 邻区。  Step 250: The RNC selects an inter-frequency neighboring cell for each cell to be optimized according to the received inter-frequency measurement report.
具体地, RNC或 SON master根据潜在邻区的下发次数、信号质量、扰码、 频点、 Ec/NO以及 RSCP来对潜在邻区进行排序, 并结合该待优化小区的异频 邻区列表中的空余位置为各待优化小区选择异频邻区, 例如, 某待优化小区 的异频邻区列表中的空余位置为 5, 则 RNC为该待优化小区选择排序为前 5 位的潜在邻区作为异频邻区。  Specifically, the RNC or the SON master sorts the potential neighbors according to the number of times the potential neighbors are sent, the signal quality, the scrambling code, the frequency point, the Ec/NO, and the RSCP, and combines the inter-frequency neighbor list of the to-be-optimized cell. The vacant location in the eNB is selected as the inter-frequency neighboring cell for each cell to be optimized. For example, if the vacant location in the inter-frequency neighboring cell list of the cell to be optimized is 5, the RNC selects the potential neighbors of the top 5 bits for the cell to be optimized. The area acts as an inter-frequency neighbor.
在步骤 210-250的为待优化小区确定异频邻区的过程中, 如果该待优化 小区有 UE发起呼叫, 或被呼叫, 则暂停当前的异频测量, RNC开始正常的 RAB请求连接, 并在呼叫结束之后, 重新计算该延长的异频测量时间并重新 开始异频测量的步骤。  In the process of determining the inter-frequency neighboring cell for the cell to be optimized in steps 210-250, if the cell to be optimized has a UE originating a call, or is called, the current inter-frequency measurement is suspended, and the RNC starts a normal RAB request connection, and After the call is over, the extended inter-frequency measurement time is recalculated and the inter-frequency measurement is restarted.
而且, 在上述步骤中, 如果当前待优化小区有一个 UE完成了 RAB释放, 可以让优先让该 UE测量潜在邻区。  Moreover, in the foregoing step, if one UE currently in the cell to be optimized completes the RAB release, the UE may be preferentially allowed to measure the potential neighboring cell.
RNC为待优化小区选择出异频邻区之后, 就可以释放 RRC连接, 或者等 到预设的时间段计时结束之后, 释放 RRC连接。  After the RNC selects the inter-frequency neighboring cell for the cell to be optimized, the RRC connection may be released, or after the preset time period is over, the RRC connection is released.
本实施例提供的异频邻区确定方法, 首先, 该方法在 UE的 RAB释放完 成之后及 RRC释放业务之间的时间段内进行, 对 UE的正常切换业务没有任 何影响, 避免了 UMTS异频邻区漏配导致的掉话和异频切换失败, 降低了掉 话率并提高了异频切换成功率。 其次, RNC根据 UE对潜在小区的实际测量 结果, 实现 UMTS ANR功能, 为待优化小区选择出异频邻区, 准确度高, 且 性能优越。 The inter-frequency neighboring cell determining method provided in this embodiment is first performed in the time period after the completion of the RAB release of the UE and the RRC release service, and has no effect on the normal handover service of the UE, and avoids the UMTS inter-frequency handover. Call drop and inter-frequency handover failure caused by neighboring area miss allocation reduce the call drop rate and improve the inter-frequency handover success rate. Second, the RNC actually measures the potential cell based on the UE. As a result, the UMTS ANR function is implemented, and the inter-frequency neighboring cell is selected for the cell to be optimized, which has high accuracy and superior performance.

The potential neighboring cell of the to-be-optimized cell to which the UE belongs is carried.
结合实施例 2可知, 在 UE的 RAB释放完成之后, RNC并不立即释放 RRC 连接, 而是延长 20-60s之后再释放 RRC连接。 在该延长的时间段内, RNC为 待优化小区中的各 UE选择出潜在邻区并将潜在邻区携带在异频测量控制信 号中下发给各 UE。  As shown in Embodiment 2, after the RAB release of the UE is completed, the RNC does not immediately release the RRC connection, but extends the RRC connection after extending the time of 20-60s. During the extended period of time, the RNC selects a potential neighboring cell for each UE in the cell to be optimized and carries the potential neighboring cell in the inter-frequency measurement control signal and sends it to each UE.
步骤 320、 UE根据接收到的异频测量控制信号对潜在邻区进行异频测 具体而言, 异频测量控制信号中包括为各 UE选择的潜在邻区, 以及各 潜在邻区的需要测量的扰码范围和频点范围。 然后, 各 UE根据接收到的异 频测量控制信号对潜在小区的扰码、 频点、 Ec/NO以及 RSCP进行异频测量。  Step 320: The UE performs inter-frequency measurement on the potential neighboring area according to the received inter-frequency measurement control signal. Specifically, the inter-frequency measurement control signal includes a potential neighboring area selected for each UE, and needs to be measured by each potential neighboring area. Scrambling code range and frequency range. Then, each UE performs inter-frequency measurement on the scrambling code, frequency point, Ec/NO, and RSCP of the potential cell according to the received inter-frequency measurement control signal.
步骤 330、 UE将异频测量结果携带在异频测量报告中发送至 RNC, 该异 频测量报告用于 RNC为待优化小区确定异频邻区。  Step 330: The UE carries the inter-frequency measurement result in the inter-frequency measurement report and sends the result to the RNC, where the inter-frequency measurement report is used by the RNC to determine the inter-frequency neighboring cell for the cell to be optimized.
UE将对潜在小区的扰码、 频点、 Ec/NO以及 RSCP的异频测量结果携带 在异频测量报告中返给 RNC, 以供 RNC为待优化小区选择异频邻区。  The UE carries the inter-frequency measurement result of the scrambling code, the frequency point, the Ec/NO and the RSCP of the potential cell in the inter-frequency measurement report and returns it to the RNC, so that the RNC selects the inter-frequency neighboring area for the cell to be optimized.
根据本实施例提供的异频邻区测量方法, UE在不依赖于标准 ANR的情 况下就能够完成对漏配邻区的测量,为 RNC提供准确的测量结果以便于 RNC 实现 UMTS ANR功能。  According to the inter-frequency neighboring cell measurement method provided by the embodiment, the UE can complete the measurement of the missing neighboring cell without relying on the standard ANR, and provide the RNC with accurate measurement results to facilitate the RNC to implement the UMTS ANR function.
