技术领域technical field

本发明涉及移动通信领域，特别涉及移动通信网络的网络规划和网络优化技术。The invention relates to the field of mobile communication, in particular to the network planning and network optimization technology of the mobile communication network.

背景技术Background technique

随着以通信技术和计算机技术为标志的高科技的发展，人们的生活发生了日新月异的巨大变化，人与人之间的信息传递越来越密切、方式也越来越多样化。蜂窝移动通信的发展给用户带来极大的便利，目前其发展已经经历了三代，分别是八十年代初以频分多址(Frequency Division Multiple Access，简称“FDMA”)技术为基础的第一代模拟移动通信系统，九十年代初以时分多址(Time Division Multiple Access，简称“TDMA”)技术为基础的第二代数字蜂窝移动通信系统，以及目前新一代的移动和个人通信系统，即以码分多址(Code Division Multiple Access，简称“CDMA”)技术为基础的第三代移动和个人通信系统。第三代移动和个人通信系统的研究和发展成为电信领域的一个热点，形成了三个主要的世界标准，宽带码分多址(WidebandCode Division Multiple Access，简称“WCDMA”)就是其中最具潜力的技术之一。With the development of high technology marked by communication technology and computer technology, people's lives have undergone tremendous changes with each passing day, and the information transmission between people is getting closer and more diverse. The development of cellular mobile communication has brought great convenience to users. At present, its development has gone through three generations. They are the first in the early 1980s based on Frequency Division Multiple Access (FDMA) technology. The first-generation analog mobile communication system, the second-generation digital cellular mobile communication system based on Time Division Multiple Access (TDMA) technology in the early 1990s, and the current new generation of mobile and personal communication systems, namely A third-generation mobile and personal communication system based on Code Division Multiple Access (CDMA) technology. The research and development of the third-generation mobile and personal communication systems has become a hot spot in the field of telecommunications, and three major world standards have been formed, among which Wideband Code Division Multiple Access (WCDMA) is the most promising One of the techniques.

在所有的蜂窝移动通信技术中，切换都是及其重要的组成部分，具体的说，当用户设备(User Equipment，简称“UE”)离开一个小区进入另外一个小区时，该UE所接收到的原来小区的信号必然越来越弱，而它所接收到的正在进入小区的信号也就将越来越强。为了保持UE的通信质量，必需将对该UE的接续由原来的基站切换到新进入的信号较强的基站。In all cellular mobile communication technologies, handover is an extremely important part. Specifically, when a user equipment (User Equipment, referred to as "UE") leaves a cell and enters another cell, the UE receives The signal of the original cell must become weaker and weaker, and the signal it receives entering the cell will also become stronger and stronger. In order to maintain the communication quality of the UE, it is necessary to switch the connection of the UE from the original base station to the newly entered base station with stronger signal.

目前主要有以下三种切换策略。At present, there are mainly three switching strategies as follows.

第一种是网络控制切换，用于最初的蜂窝移动通信系统；第二种是UE辅助切换，用于诸如全球移动通信系统(Global System for mobileCommunication，简称“GSM”)、IS-95系统等更新的系统、以及WCDMA系统，在这种切换策略中，UE和基站分别对前向和反向信道的质量，诸如接收场强指示(Receiving Signal Strength Indicator，简称“RSSI”)、信号干扰比(Signal to Interference Ratio，简称“SIR”)、误比特率(Bit Error Rate，简称“BER”)等进行测量，并分别将测量结果上报给网络侧，网络侧根据测量结果进行切换判决，在目标小区的信号质量符合要求时进行切换。因此，在UE辅助切换的策略中，UE需要不断检测目标小区的信号质量。还有一种是UE控制切换。The first is network-controlled handover, which is used in the original cellular mobile communication system; the second is UE-assisted handover, which is used for updates such as Global System for mobile Communication (GSM for short), IS-95 system, etc. systems, and WCDMA systems, in this handover strategy, the UE and the base station respectively check the quality of the forward and reverse channels, such as the receiving field strength indicator (Receiving Signal Strength Indicator, referred to as "RSSI"), signal-to-interference ratio (Signal to Interference Ratio, referred to as "SIR"), Bit Error Rate (Bit Error Rate, referred to as "BER"), etc., and report the measurement results to the network side respectively, and the network side makes a handover decision based on the measurement results, and the target cell Switch when the signal quality meets the requirements. Therefore, in the UE-assisted handover strategy, the UE needs to continuously detect the signal quality of the target cell. There is another kind of handover controlled by UE.

根据进行切换的源小区和目标小区的不同，小区间的切换可以分为同频小区之间的切换、异频小区之间的切换、以及异系统邻区之间的切换。在系统发展的初期，由于频点单一，通常采用同频切换，但随着用户数的不断增多和网络的演进，单个频点往往不能满足容量的要求，需要叠加新的频点，由此便引入了不同频点间的测量与切换。并且，考虑到对现有GSM网络的利用，还引入了异系统间的检测和切换。According to the difference between the source cell and the target cell for handover, inter-cell handover can be divided into handover between same-frequency cells, handover between different-frequency cells, and handover between neighboring cells of different systems. In the initial stage of system development, due to the single frequency point, same-frequency handover is usually used, but with the increasing number of users and the evolution of the network, a single frequency point often cannot meet the capacity requirements, and new frequency points need to be superimposed. The measurement and switching between different frequency points are introduced. Moreover, considering the utilization of the existing GSM network, detection and switching between different systems are also introduced.

另外，当UE处于空闲或非小区专用信道状态(非CELL-DCH)时，UE驻留小区的变更通过小区重选过程完成，同样需要对目标小区进行检测，在符合要求时进行小区重选。In addition, when the UE is in an idle or non-cell-dedicated channel state (non-CELL-DCH), the change of the UE's camping cell is completed through the cell reselection process. It is also necessary to detect the target cell and perform cell reselection when it meets the requirements.

在现有技术中，当UE远离源小区，需要进行切换时，或处于空闲/非CELL-DCH状态，需要进行小区重选时，首先由网络侧向UE广播或发送测量邻区列表，为其确定目标小区，之后，由UE对目标小区的质量进行检测。目标小区的测量主要在压缩模式下进行。压缩模式在蜂窝移动通信中应用十分普遍，例如，在CDMA系统中，移动终端进行异频硬切换前，网络侧会要求UE进行异频检测，在异频检测中，由UE发起对邻近异频小区公共导频信道(Common Pilot Channel，简称“CPICH”)的信噪比(Ec/No)或接受信号码功率(RSCP)的测量，以得到异频小区的信道质量，该测量需要在压缩模式下进行。In the prior art, when the UE is far away from the source cell and needs to be handed over, or is in an idle/non-CELL-DCH state and needs to perform cell reselection, the network first broadcasts or sends the measured neighbor list to the UE for its The target cell is determined, and then the quality of the target cell is detected by the UE. The measurement of the target cell is mainly carried out in compressed mode. Compressed mode is widely used in cellular mobile communications. For example, in a CDMA system, before a mobile terminal performs inter-frequency hard handover, the network side will require the UE to perform inter-frequency detection. The measurement of the signal-to-noise ratio (Ec/No) or received signal code power (RSCP) of the common pilot channel (Common Pilot Channel, referred to as "CPICH") to obtain the channel quality of the inter-frequency cell, this measurement needs to be performed in compressed mode next.

又例如，当UE的源小区为CDMA系统小区，而所切换的目标小区为GSM系统小区时，在进行从CDMA系统小区到GSM系统小区的异系统切换之前，网络侧同样会要求UE进行异系统测量，为系统间切换判决提供必要的信息。此时，由于GSM系统的频率不相同，也需要启动压缩模式测量邻近GSM小区的频率信号。其测量该过程大致为三个阶段：For another example, when the UE's source cell is a CDMA system cell and the handover target cell is a GSM system cell, the network side will also require the UE to perform an inter-system handover before performing an inter-system handover from a CDMA system cell to a GSM system cell. Measurements provide necessary information for inter-system handover decisions. At this time, since the frequency of the GSM system is different, it is also necessary to start the compressed mode to measure the frequency signal of the adjacent GSM cell. It measures the process roughly in three stages:

第一个阶段，UE发起对邻近GSM小区广播信道RSSI的测量；第二个阶段，UE选择其中8个RSSI最强的基站，捕获同步突发(SynchronizationBurst，简称“SB”)，解码出基站识别码(Base Station Identify Code，简称“BSIC”)和GSM小区观察时间差信息；第三个阶段，成功获得BSIC后不断的重新确认BSIC的值，以免BSIC发生变化，并更新GSM小区观察时间差信息。In the first stage, the UE initiates the measurement of the RSSI of the broadcast channel of the adjacent GSM cell; in the second stage, the UE selects eight base stations with the strongest RSSI, captures a Synchronization Burst ("SB"), and decodes the base station identification Code (Base Station Identify Code, referred to as "BSIC") and GSM cell observation time difference information; in the third stage, after successfully obtaining BSIC, the value of BSIC is continuously reconfirmed to prevent BSIC from changing, and the GSM cell observation time difference information is updated.

在实际应用中，上述方案存在以下问题：现有技术中对相邻小区进行检测的方法对UE的通信存在副作用，且该方法十分依赖网络规化，无法自行检测到网络侧的邻区列表中遗漏的相邻小区。In practical application, the above solution has the following problems: the method of detecting adjacent cells in the prior art has side effects on UE communication, and this method is very dependent on network planning, and cannot automatically detect neighbor cells on the network side. Missed neighboring cells.

造成这种情况的主要原因在于，UE要通过压缩模式进行小区间测量与切换，首先需要通过网络侧为其确定目标小区，现有技术主要通过网络侧向UE广播或发送测量邻区列表进行确定。然而这一方法对网络规划即配置依赖程度较大，使得网络规划和优化工作量太大，而对于邻区列表中遗漏的相邻小区，无法进行切换或检测。The main reason for this situation is that if UE needs to perform inter-cell measurement and handover in compressed mode, it first needs to determine the target cell for it through the network side. In the existing technology, the network side broadcasts or sends the measurement neighbor list to the UE to determine. . However, this method relies heavily on network planning, that is, configuration, which makes the workload of network planning and optimization too large, and handover or detection cannot be performed for adjacent cells that are missing in the neighbor list.

通过比较可以发现，本发明的技术方案与现有技术的主要区别在于，通过UE对邻区信号进行测量，并根据UE所上报的测量结果，判断是否有网络规划中非邻区的小区的信号质量达到邻区信号质量的要求，如果有，则该小区为UE服务小区的漏配邻区。利用UE实现了一种自动检测漏配邻区的功能，从而减少了网规优化的工作量，为专用信道的UE的通话质量提供了保证。Through comparison, it can be found that the main difference between the technical solution of the present invention and the prior art is that the UE measures the signal of the adjacent cell, and judges whether there is a signal of a non-adjacent cell in the network planning according to the measurement result reported by the UE. The quality meets the signal quality requirements of neighboring cells. If yes, the cell is a missed neighbor cell of the serving cell of the UE. The UE implements a function of automatically detecting missing adjacent cells, thereby reducing the workload of network planning and optimization, and guaranteeing the call quality of UEs with dedicated channels.

网络侧仅通知处于非小区专用信道状态的UE进行测量，使得接收到通知的UE可以有更多的时间用于执行对邻区的测量，尤其是异频、异系统的小区测量，并且进行小区搜索的过程不会影响到服务质量。The network side only notifies UEs in the non-cell-dedicated channel state to perform measurements, so that the UEs that receive the notification can have more time to perform measurements on neighboring cells, especially inter-frequency and inter-system cell measurements, and perform cell measurements. The search process does not affect the quality of service.

UE测量的邻区是同频邻区或异频邻区或异系统邻区，适用的邻区类型较为广泛。The neighboring cell measured by the UE is the same-frequency neighboring cell or a different-frequency neighboring cell or a different-system neighboring cell, and a wide range of neighboring cell types are applicable.

网络侧向UE下发测量结果的上报条件，UE仅在测量结果符合该上报条件时，将该测量结果上报给网络侧，避免了UE上报较多的无效值，从而节约了系统的空口资源，并且也减小了网络侧对测量结果的处理负担。The network side sends the reporting condition of the measurement result to the UE, and the UE reports the measurement result to the network side only when the measurement result meets the reporting condition, which avoids the UE reporting many invalid values, thereby saving the air interface resources of the system. In addition, the processing load on the measurement result on the network side is also reduced.

网络侧随机选择小区中部分的UE对邻区进行测量，避免了过多的UE因同时处于漏配邻区的检测和上报状态而导致的重复报告。The network side randomly selects some UEs in the cell to measure neighboring cells, which avoids repeated reports caused by too many UEs being in the detection and reporting state of missing neighboring cells at the same time.

由网络侧控制UE的测量时间，避免了由于UE始终处于漏配邻区的检测状态而导致损耗过多电池的情况。The measurement time of the UE is controlled by the network side, which avoids excessive battery consumption due to the UE being always in the detection state of missing neighboring cells.

具体实施方式Detailed ways

为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述。In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

本发明核心在于，网络侧通知UE对邻区信号进行测量，并根据UE所上报的测量结果，判断是否存在信号质量超过预设门限，且在网络规划中未被规化为邻区的小区，如果有，则判定该小区为UE服务小区的漏配邻区，可以进一步将该小区添加为该服务小区的邻区。从而实现了自动检测漏配邻区的功能，减少了网规优化的工作量，为UE的通话质量提供了保证。The core of the present invention is that the network side notifies the UE to measure the signal of the neighboring cell, and judges whether there is a cell whose signal quality exceeds the preset threshold and is not planned as a neighboring cell in the network planning according to the measurement result reported by the UE. If so, it is determined that the cell is a missing neighboring cell of the serving cell of the UE, and the cell may be further added as a neighboring cell of the serving cell. In this way, the function of automatically detecting missing adjacent cells is realized, the workload of network planning optimization is reduced, and the call quality of UE is guaranteed.

下面根据发明原理对本发明第一实施方式漏配邻区的检测方法进行说明。The method for detecting missing adjacent cells in the first embodiment of the present invention will be described below according to the principle of the invention.

在本实施方式中，参与漏配邻区检测的UE为处于非CELL-DCH状态的UE，所检测的邻区为同频/异频邻区。网络侧在需要对服务小区进行同频/异频邻区的漏配检测时，首先对漏配邻区检测参数进行配置。In this embodiment, the UEs that participate in the detection of missing adjacent cells are UEs in the non-CELL-DCH state, and the detected adjacent cells are intra-frequency/inter-frequency adjacent cells. When the network side needs to perform the missing configuration detection of the same-frequency/inter-frequency neighboring cells for the serving cell, it first configures the missing configuration detection parameters of the neighboring cells.

具体的配置过程如图1所示，在步骤110中，网络侧首先判断漏配邻区检测功能是否打开，如果是则进入步骤120，反之则结束本流程。The specific configuration process is shown in Figure 1. In step 110, the network side first judges whether the missing neighbor cell detection function is enabled, and if so, enters step 120, otherwise, ends the process.

在步骤120中，网络侧对要求UE检测的频点范围进行配置。对于异频小区的漏配检测，即配置所需检测的异频频点范围，对于同频小区的漏配检测，其频点范围即该频点本身。In step 120, the network side configures the range of frequency points that the UE is required to detect. For the missing configuration detection of inter-frequency cells, that is, configure the range of inter-frequency frequency points that need to be detected. For the missing configuration detection of same-frequency cells, the frequency point range is the frequency point itself.

接着进入步骤130，网络侧进一步设定漏配邻区检测结果上报条件，上报条件包含CPICH Ec/No或CPICH RSCP的第一绝对值以及迟延触发时间，如果UE对小区的测量结果为在该迟延触发时间内的CPICH Ec/No或CPICHRSCP大于该第一绝对值，则该测量结果满足上报条件。Then enter step 130, the network side further sets the reporting condition of the detection result of the missing adjacent cell, the reporting condition includes the first absolute value of CPICH Ec/No or CPICH RSCP and the delay trigger time, if the measurement result of the UE to the cell is within the delay If the CPICH Ec/No or CPICH RSCP within the trigger time is greater than the first absolute value, the measurement result meets the reporting condition.

接着进入步骤140，网络侧预先设置随机因子，随机因子是一个数值，例如如预先设置一个0.8的值作为随机因子，以便随机选择进行漏配邻区检测的UE。Then enter step 140, the network side presets a random factor, the random factor is a value, for example, a value of 0.8 is preset as the random factor, so as to randomly select UEs for missing neighbor cell detection.

在完成对各邻区检测参数的配置后，网络侧通过下发系统广播消息通知处于非CELL-DCH状态的UE对本服务小区的邻区信号进行测量，该系统广播消息中包含以上所配置的所有漏配邻区检测参数。由于网络侧仅通知处于非CELL-DCH状态的UE进行邻区信号测量，从而进行小区搜索的过程并不会影响到CELL-DCH状态的UE的通信质量。After completing the configuration of each neighbor cell detection parameter, the network side notifies the UE in the non-CELL-DCH state to measure the signal of the neighbor cell of the serving cell by sending a system broadcast message. The system broadcast message contains all the parameters configured above. Missing adjacent cell detection parameters. Since the network side only notifies the UE in the non-CELL-DCH state to perform neighbor cell signal measurement, the process of cell search will not affect the communication quality of the UE in the CELL-DCH state.

在UE侧，接收到该系统广播消息的UE随机地根据漏配邻区检测参数对邻区相关信号进行测量，并将满足上报条件的测量结果上报网络侧。On the UE side, the UE receiving the system broadcast message randomly measures the neighbor cell-related signals according to the missing neighbor cell detection parameters, and reports the measurement results that meet the reporting conditions to the network side.

具体地说，如图2所示，当处于非CELL-DHC状态的UE需要变更其驻留小区时，读取系统广播消息，检查当前网络侧是否下发了漏配邻区检测的系统广播消息，在检测到该系统广播消息时，进入步骤210，UE首先产生一个随机数，与系统广播消息中的随机因子相比较，根据比较结果来决定是否需要对邻区信号进行测量。在本实施方式中，如果UE产生的随机数大于该随机因子时，则说明该UE需要对邻区信号进行测量，否则该UE不需要对邻区信号进行测量。比如说，系统广播消息中的随机因子为0.8，UE在检测到该系统广播消息时生成一个0至1范围内的随机数，例如为0.9，那么，该UE则需要对邻区信号进行测量。Specifically, as shown in Figure 2, when a UE in a non-CELL-DHC state needs to change its cell, it reads the system broadcast message and checks whether the current network side has issued a system broadcast message for detection of missing adjacent cells , when the system broadcast message is detected, enter step 210, the UE first generates a random number, compares it with the random factor in the system broadcast message, and decides whether to measure neighboring cell signals according to the comparison result. In this embodiment, if the random number generated by the UE is greater than the random factor, it means that the UE needs to measure the signal of the neighboring cell; otherwise, the UE does not need to measure the signal of the neighboring cell. For example, the random factor in the system broadcast message is 0.8, and when the UE detects the system broadcast message, it generates a random number ranging from 0 to 1, such as 0.9, then the UE needs to measure the signals of neighboring cells.

如果UE不需要对邻区信号进行测量，则进入步骤220，按正常流程发起小区重选的过程；如果UE需要对邻区信号进行测量，则进入步骤230。If the UE does not need to measure signals of neighboring cells, it proceeds to step 220, and initiates a cell reselection process according to a normal procedure; if the UE needs to measure signals of neighboring cells, it proceeds to step 230.

通过将所产生的随机数与网络侧下发的随机因子相比较，随机地选择部分UE对邻区信号进行测量，避免了过多的UE同时进行漏配邻区检测，导致不必要的资源浪费。By comparing the generated random number with the random factor sent by the network side, some UEs are randomly selected to measure the signal of the neighboring cell, which avoids unnecessary waste of resources caused by too many UEs performing missing neighbor cell detection at the same time .

在步骤230中，UE对同频频点以及该系统消息中所配置的异频频点范围内的邻区信号进行测量。具体地说，UE根据该同频频点以及该异频频点范围进行小区搜索，搜索相关小区扰码，测量频点范围内小区的CPICH Ec/No和CPICH RSCP，并对测量结果进行滤波。In step 230, the UE measures signals of adjacent cells within the range of the same-frequency frequency point and the different-frequency frequency point configured in the system message. Specifically, the UE performs cell search according to the same frequency point and the different frequency point range, searches for relevant cell scrambling codes, measures CPICH Ec/No and CPICH RSCP of cells within the frequency point range, and filters the measurement results.

接着进入步骤240，UE根据网络侧所配置的上报条件，判断该测量结果是否需要上报网络侧。具体地说，根据网络侧所配置的上报条件，如果UE的测量结果为在迟延触发时间内的CPICH Ec/No或CPICH RSCP大于第一绝对值，则判定该测量结果满足上报条件，进入步骤250，通过随机接入信道(Random Access CHannel，简称“RACH”)报告将该测量结果上报网络侧，由于UE仅在测量结果符合上报条件时，将该测量结果上报给网络侧，避免了UE上报较多的无效值，从而节约了系统的空口资源，并且也减小了网络侧对测量结果的处理负担；反之，如果UE的测量结果为在迟延触发时间内的CPICH Ec/No和CPICH RSCP不大于第一绝对值，则判定该测量结果不满足上报条件，进入步骤260，UE进一步判断当前是否已达到网络侧预先设置的测量时间，如果是则进入步骤270，UE停止对服务小区的邻区信号进行测量，避免了由于UE始终处于漏配邻区的检测状态而导致损耗过多电池的情况；反之则返回步骤230，继续对频点范围内的小区信号进行测量。Then enter step 240, the UE judges whether the measurement result needs to be reported to the network side according to the reporting condition configured by the network side. Specifically, according to the reporting condition configured on the network side, if the measurement result of the UE is that the CPICH Ec/No or CPICH RSCP within the delay trigger time is greater than the first absolute value, then it is determined that the measurement result meets the reporting condition, and enter step 250 , report the measurement result to the network side through a random access channel (Random Access CHannel, referred to as "RACH") report, because the UE reports the measurement result to the network side only when the measurement result meets the reporting conditions, avoiding the UE reporting Many invalid values, thus saving the air interface resources of the system, and also reducing the processing burden of the measurement results on the network side; on the contrary, if the measurement results of the UE are that the CPICH Ec/No and CPICH RSCP within the delay trigger time are not greater than If the first absolute value is the first absolute value, it is determined that the measurement result does not meet the reporting conditions, and the UE proceeds to step 260. The UE further determines whether the measurement time preset by the network side has been reached, and if so, proceeds to step 270. The measurement is performed to avoid excessive battery consumption due to the UE being in the detection state of missing neighboring cells all the time; otherwise, return to step 230 and continue to measure cell signals within the frequency range.

在另一侧，网络侧在下发漏配邻区检测的系统广播消息后，等待接收来自非CELL-DCH状态的UE的RACH报告，当收到UE的RACH报告时，根据报告中的测量结果判定当前是否存在漏配的邻区。On the other side, after sending the system broadcast message for detection of missing adjacent cells, the network side waits to receive the RACH report from the UE in the non-CELL-DCH state. When receiving the RACH report from the UE, it judges according to the measurement results in the report Whether there are currently missing adjacent cells.

具体地说，如图3所示，网络侧在接收到来自UE的RACH报告时，进入步骤310，根据UE上报的测量结果判断网络规划中非邻区的小区的信号质量是否达到邻区信号质量的要求，如果是，则判定该小区为UE服务小区的漏配邻区，进入步骤320；反之则判定当前不存在漏配的邻区，结束本流程。Specifically, as shown in Figure 3, when the network side receives the RACH report from the UE, it enters step 310, and judges whether the signal quality of the non-neighboring cell in the network planning reaches the signal quality of the neighboring cell according to the measurement result reported by the UE. If yes, it is determined that the cell is a missing neighbor cell of the serving cell of the UE, and proceeds to step 320; otherwise, it is determined that there is no missing neighbor cell, and the process ends.

在步骤320中，向话务统计上报漏配小区。In step 320, the missing cell is reported to traffic statistics.

接着进入步骤330，网络侧进一步判断该漏配的同频/异频小区的测量结果是否大于同频/异频切换门限，且该小区自动更新功能是否打开。如果是则进入步骤340，将该小区自动添加到服务小区的同频/异频邻区中；反之则结束本流程。Then enter step 330, the network side further judges whether the measurement result of the missing same-frequency/different-frequency cell is greater than the same-frequency/different-frequency handover threshold, and whether the automatic update function of the cell is enabled. If yes, go to step 340, and automatically add the cell to the same-frequency/different-frequency neighboring cells of the serving cell; otherwise, end this procedure.

其中，本实施方式中UE的服务小区为WCDMA系统小区。Wherein, in this embodiment, the serving cell of the UE is a WCDMA system cell.

下面对本发明第二实施方式的漏配邻区的检测方法进行说明。The method for detecting a missing adjacent cell according to the second embodiment of the present invention will be described below.

在本实施方式中，参与漏配邻区检测的UE为处于非CELL-DCH状态的UE，所检测的邻区为异系统邻区。网络侧在需要对服务小区进行异系统邻区的漏配检测时，首先对漏配邻区检测参数进行配置。In this embodiment, the UE participating in the detection of the missing neighbor cell is a UE in the non-CELL-DCH state, and the detected neighbor cell is a neighbor cell of a different system. When the network side needs to detect the missing configuration of neighboring cells of different systems on the serving cell, it first configures the detection parameters of missing neighboring cells.

具体的配置过程如图4所示，在步骤410中，网络侧首先判断漏配邻区检测功能是否打开，如果是则进入步骤420，反之结束本流程。The specific configuration process is shown in Figure 4. In step 410, the network side first judges whether the missing neighbor cell detection function is enabled, and if so, enters step 420, otherwise ends the process.

在步骤420中，网络侧对要求UE检测的异系统频点范围进行配置。In step 420, the network side configures the frequency point range of the different system that the UE is required to detect.

接着进入步骤430，网络侧进一步设定漏配邻区检测结果上报条件，上报条件包含广播控制信道(Broadcast Control Channel，简称“BCCH”)RSSI的第二绝对值、以及迟延触发时间，如果UE的测量结果为在该迟延触发时间内的BCCH RSSI大于该第二绝对值，则该测量结果满足上报条件。Then enter step 430, and the network side further sets the reporting conditions of the detection result of missing adjacent cells. The reporting conditions include the second absolute value of the broadcast control channel (Broadcast Control Channel, referred to as "BCCH") RSSI and the delay trigger time. If the measurement result is that the BCCH RSSI within the delayed trigger time is greater than the second absolute value, then the measurement result meets the reporting condition.

接着进入步骤440，网络侧预先设置随机因子，以便随机选择进行漏配邻区检测的UE。Then enter step 440, where the network side presets a random factor so as to randomly select UEs for missing neighbor cell detection.

在完成对邻区检测参数的配置后，网络侧通过下发系统广播消息通知处于非CELL-DCH状态的UE对本服务小区的邻区信号进行测量，该系统广播消息中包含以上所配置的所有漏配邻区检测参数。由于网络侧仅通知处于非CELL-DCH状态的UE进行邻区信号测量，从而进行小区搜索的过程并不会影响到CELL-DCH状态的UE的通信质量。After completing the configuration of the neighbor cell detection parameters, the network side notifies the UE in the non-CELL-DCH state to measure the signal of the neighbor cell of the serving cell by sending a system broadcast message. The system broadcast message contains all the leaks configured above. Configure neighbor detection parameters. Since the network side only notifies the UE in the non-CELL-DCH state to perform neighbor cell signal measurement, the process of cell search will not affect the communication quality of the UE in the CELL-DCH state.

在UE侧，接收到该系统广播消息的UE随机地根据漏配邻区检测参数对邻区相关信号进行测量，并将满足上报条件的测量结果上报网络侧。On the UE side, the UE receiving the system broadcast message randomly measures the neighbor cell-related signals according to the missing neighbor cell detection parameters, and reports the measurement results that meet the reporting conditions to the network side.

具体地说，如图5所示，当处于非CELL-DHC状态的UE需要变更其驻留小区时，读取系统广播消息，检查当前网络侧是否下发了漏配邻区检测的系统广播消息，在检测到该系统广播消息时，进入步骤510，UE首先产生一个随机变量，与系统广播消息中的随机因子相比较，如果所产生的随机变量大于消息中的随机因子，则进入步骤520，按照现有技术发起小区重选的过程；反之，则进入步骤530。通过将所产生的随机数与网络侧下发的随机因子相比较，随机地选择部分UE对邻区信号进行测量，避免了过多的UE同时进行漏配邻区检测，导致不必要的资源浪费。Specifically, as shown in Figure 5, when a UE in a non-CELL-DHC state needs to change its cell, it reads the system broadcast message and checks whether the current network side has issued a system broadcast message for missing neighbor cell detection , when the system broadcast message is detected, enter step 510, UE first generates a random variable, compares it with the random factor in the system broadcast message, if the generated random variable is greater than the random factor in the message, then enters step 520, The process of initiating cell reselection according to the prior art; otherwise, enter step 530 . By comparing the generated random number with the random factor sent by the network side, some UEs are randomly selected to measure the signal of the neighboring cell, which avoids unnecessary waste of resources caused by too many UEs performing missing neighbor cell detection at the same time .

在步骤530中，UE对系统消息中所配置的异系统频点范围内的邻区信号进行测量。具体地说，UE根据该异系统频点范围，进行异系统小区的搜索，并解码BSIC，测量BCCH RSSI。In step 530, the UE measures signals of neighboring cells within the range of different system frequency points configured in the system message. Specifically, the UE searches for different-system cells according to the different-system frequency point range, decodes BSIC, and measures BCCH RSSI.

接着进入步骤540，UE根据网络侧所配置的上报条件，判断该测量结果是否需要上报网络侧。具体地说，根据网络侧所配置的上报条件，如果UE的测量结果为在迟延触发时间内的BCCH RSSI大于第二绝对值，则判定该测量结果满足上报条件，进入步骤550，通过RACH报告将该测量结果上报网络侧，由于UE仅在测量结果符合上报条件时，将该测量结果上报给网络侧，避免了UE上报较多的无效值，从而节约了系统的空口资源，并且也减小了网络侧对测量结果的处理负担；反之，如果UE的测量结果为在迟延触发时间内的BCCH RSSI不大于第二绝对值，则判定该测量结果不满足上报条件，进入步骤560，UE进一步判断当前是否已达到网络侧预先设置的测量时间，如果是则进入步骤570，UE停止对服务小区的邻区信号进行的测量，避免了由于UE始终处于漏配邻区的检测状态而导致损耗过多电池的情况；反之则返回步骤530，继续对异系统频点范围内的小区进行测量。Then enter step 540, the UE judges whether the measurement result needs to be reported to the network side according to the reporting condition configured on the network side. Specifically, according to the reporting condition configured on the network side, if the measurement result of the UE is that the BCCH RSSI within the delay trigger time is greater than the second absolute value, then it is determined that the measurement result meets the reporting condition, and enter step 550, and report the The measurement result is reported to the network side. Since the UE reports the measurement result to the network side only when the measurement result meets the reporting conditions, the UE is prevented from reporting many invalid values, thereby saving the air interface resources of the system and reducing the The processing burden of the measurement result on the network side; on the contrary, if the measurement result of the UE is that the BCCH RSSI within the delay trigger time is not greater than the second absolute value, it is determined that the measurement result does not meet the reporting condition, and enters step 560, and the UE further judges that the current Whether it has reached the measurement time preset by the network side, if yes, enter step 570, the UE stops measuring the signal of the neighboring cell of the serving cell, and avoids excessive battery loss due to the fact that the UE is always in the detection state of missing neighboring cells otherwise, return to step 530, and continue to measure cells within the frequency range of the different system.

在另一侧，网络侧在下发漏配邻区检测的系统广播消息后，等待接收来自非CELL-DCH状态的UE的RACH报告，当收到UE的RACH报告时，根据报告中的测量结果判定当前是否存在漏配的异系统邻区，如果有，则用添加同频/异频邻区的类似方法，将该异系统小区自动添加到服务小区的异系统邻区中。On the other side, after sending the system broadcast message for detection of missing adjacent cells, the network side waits to receive the RACH report from the UE in the non-CELL-DCH state. When receiving the RACH report from the UE, it judges according to the measurement results in the report Whether there are currently missing inter-system neighboring cells, and if so, use a similar method of adding same-frequency/inter-frequency neighboring cells to automatically add the inter-system cell to the inter-system neighboring cells of the serving cell.

在本实施方式中UE的服务小区为WCDMA系统小区，异系统为GSM系统，异系统小区为GSM系统小区。In this embodiment, the serving cell of the UE is a WCDMA system cell, the other system is a GSM system, and the other system cell is a GSM system cell.

其中，网络侧在现有技术的基础上还包含收发模块和检测模块，收发模块用于通知UE对邻区信号进行测量，并接收该UE上报的测量结果；检测模块用于根据UE上报的测量结果判断是否有网络规划中非邻区的小区的信号质量超过预设门限。Among them, the network side also includes a transceiver module and a detection module on the basis of the existing technology. The transceiver module is used to notify the UE to measure the signal of the neighboring cell and receive the measurement result reported by the UE; As a result, it is judged whether the signal quality of any non-adjacent cell in the network planning exceeds the preset threshold.

UE在现有技术的基础上还包含测量模块、上报模块和判断模块，测量模块用于在接收到通知时对本UE的邻区信号进行测量；上报模块用于将测量模块的测量结果上报给网络侧；判断模块用于判断测量模块的测量结果是否满足网络侧下发的上报条件。On the basis of the existing technology, the UE also includes a measurement module, a reporting module and a judgment module. The measurement module is used to measure the neighboring cell signal of the UE when receiving the notification; the reporting module is used to report the measurement results of the measurement module to the network. side; the judgment module is used to judge whether the measurement result of the measurement module satisfies the reporting condition issued by the network side.

具体地说，在需要进行漏配邻区检测时，网络侧通过收发模块把漏配邻区的检测参数发送给处于CELL-DCH状态的UE，通知其对检测参数指示的范围内的邻区信号进行测量。UE接收到该通知后，通过测量模块对所指示的范围内的邻区信号进行测量，并通过判断模块判断该测量结果是否满足网络侧下发的上报条件，如果满足，则指示上报模块将该测量结果上报给网络侧。网络侧通过收发模块接收来自UE的测量结果，由检测模块根据测量结果判断是否有网络规划中非邻区的小区的信号质量超过预设门限，如果有，则判定该小区为UE服务小区的漏配邻区。由于本实施方式通过利用UE实现了自动检测漏配邻区的功能，从而减少了网规优化的工作量，为专用信道的UE的通话质量提供了保证。Specifically, when it is necessary to detect missing neighboring cells, the network side sends the detection parameters of missing neighboring cells to the UE in the CELL-DCH state through the transceiver module, and notifies it of the neighboring cell signals within the range indicated by the detection parameters. Take measurements. After receiving the notification, the UE uses the measurement module to measure the signals of neighboring cells within the indicated range, and uses the judging module to judge whether the measurement result satisfies the reporting conditions issued by the network side, and if so, instructs the reporting module to send the The measurement results are reported to the network side.
