背景技术Background technique
随着移动通信技术的蓬勃发展，GSM(Global System of Mobile Communi-cation,全球移动通讯系统)、UMTS(Universal Mobile Telecommunications System,通用移动通信系统)、LTE(Long Term Evolution,长期演进)等通信网络应运而生。而UE(UserEquipment，用户设备)可处于上述任一通讯网络所覆盖的小区内进行通信。当UE移动至其所在小区的边缘时，为了保持UE的正常通信状态，如何控制UE进行小区切换，成为了一个关键问题。With the vigorous development of mobile communication technology, communication networks such as GSM (Global System of Mobile Communication, Global System for Mobile Communications), UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System), LTE (Long Term Evolution, Long Term Evolution) Came into being. A UE (User Equipment, user equipment) may communicate in a cell covered by any one of the above-mentioned communication networks. When the UE moves to the edge of the cell where it is located, in order to maintain the normal communication state of the UE, how to control the UE to perform cell handover becomes a key issue.
现有技术中，UE(User Equipment，用户设备)测量待切换小区的下行电平，在得到下行电平的测量数据后，将下行电平的测量数据上报至基站，之后由基站根据下行电平的测量数据进行切换判决，当判决下行电平的测量数据大于预设门限时，控制UE进行小区切换，以使UE切换到目标切换小区。In the prior art, the UE (User Equipment, user equipment) measures the downlink level of the cell to be switched, and after obtaining the measurement data of the downlink level, reports the measurement data of the downlink level to the base station, and then the base station according to the downlink level Handover decision is made based on the measured data of the downlink level, and when the measured data of downlink level is judged to be greater than the preset threshold, the UE is controlled to perform cell handover, so that the UE is handed over to the target handover cell.
在实现本发明的过程中，发明人发现现有技术至少存在以下问题：In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art:
如果目标切换小区的下行电平良好，但存在下行干扰，导致下行质量较差，则在UE切换到该目标切换小区后，由于下行质量较差，UE将无法解码，从而导致UE无法进行正常通信；如果目标切换小区的上下行链路不均衡或目标切换小区存在上行干扰，则在UE切换到该目标切换小区后，由于UE发射的信号功率衰减过大或上行质量较差，基站无法解码，从而导致UE无法进行正常通信。If the downlink level of the target switching cell is good, but there is downlink interference, resulting in poor downlink quality, after the UE switches to the target switching cell, the UE will not be able to decode due to the poor downlink quality, resulting in the UE being unable to perform normal communication ; If the uplink and downlink of the target handover cell are unbalanced or there is uplink interference in the target handover cell, after the UE is handed over to the target handover cell, the base station cannot decode the signal due to excessive power attenuation or poor uplink quality of the signal transmitted by the UE. As a result, the UE cannot perform normal communication.

实施例二Embodiment two
本发明实施例提供了一种小区切换的控制方法，现结合上述实施例一的内容，以UE当前处于UMTS小区，其各个待切换小区为GSM网络下的各个GSM小区为例，对本实施例提供的小区切换的控制方式进行详细阐述；其中UMTS小区的控制器为RNC(Radio NetworkController，无线网络控制器)，GSM小区的控制器为BSC(Base Station Controller，基站控制器)，且一个BSC可控制多个GSM小区。参见图2，本实施例提供的方法流程包括：The embodiment of the present invention provides a method for controlling cell handover. In combination with the content of the first embodiment above, taking the UE currently in a UMTS cell and each cell to be handed over to be each GSM cell under the GSM network as an example, this embodiment provides The control mode of the cell handover is described in detail; wherein the controller of the UMTS cell is RNC (Radio Network Controller, radio network controller), the controller of the GSM cell is BSC (Base Station Controller, base station controller), and a BSC can control Multiple GSM cells. Referring to Figure 2, the method flow provided by this embodiment includes:
201：RNC获取各个GSM小区的下行电平值；201: The RNC obtains the downlink level value of each GSM cell;
针对该步骤，RNC获取各个GSM小区的下行电平值，包括但不限于如下方式：For this step, the RNC obtains the downlink level value of each GSM cell, including but not limited to the following methods:
接收UE上报的各个GSM小区的下行电平值。Receive the downlink level value of each GSM cell reported by the UE.
其中，UE具体可为智能终端、多媒体设备、流媒体设备、无线调制解调器、无线本地环路台、移动台或用户单元等等，且UE可处于小区中的任意位置，其既可是静止的也可是移动的。Among them, the UE can specifically be an intelligent terminal, a multimedia device, a streaming media device, a wireless modem, a wireless local loop station, a mobile station or a subscriber unit, etc., and the UE can be located in any position in the cell, and it can be either stationary or mobile.
当UE处于UMTS小区及GSM小区的交界处时，UE测量GSM小区的下行电平值，在得到GSM小区的下行电平值后，将该下行电平值上报给RNC，即RNC获取到GSM小区的下行电平值。When the UE is at the junction of the UMTS cell and the GSM cell, the UE measures the downlink level value of the GSM cell, and after obtaining the downlink level value of the GSM cell, reports the downlink level value to the RNC, that is, the RNC acquires the GSM cell downlink level value.
202:RNC获取各个GSM小区的上、下行电平值与上、下行信号接收质量值之间的对应关系表；202: RNC obtains the corresponding relationship table between the uplink and downlink level values and uplink and downlink signal reception quality values of each GSM cell;
其中，RNC获取各个GSM小区的上、下行电平值与上、下行信号接收质量值的对应关系表，包括但不限于如下方式：Wherein, the RNC obtains the corresponding relationship table between the uplink and downlink level values of each GSM cell and the uplink and downlink signal reception quality values, including but not limited to the following methods:
接收各个GSM小区的BSC发送的各个GSM小区的上、下行电平值与上、下行信号接收质量值之间的对应关系表。A correspondence table between uplink and downlink level values and uplink and downlink signal reception quality values of each GSM cell sent by the BSC receiving each GSM cell.
进一步地，GSM小区的BSC在发送GSM小区的上、下行电平值与上、下行信号接收质量值之间的对应关系表之前，会预先收集其下各个GSM小区的上、下行电平值及上下行信号接收质量，且BSC在收集各个GSM小区的上、下行电平值及上下行信号接收质量时，会设置一个供数据采集的UE，由该UE进行各个GSM小区的下行电平及下行信号接收质量的测量及上报，而各个GSM小区的上行电平及上行信号接收质量则由BTS(Base Transceiver Station，基站收发台)测量及上报。之后BSC便可根据各个GSM小区的上、下行电平值及上下行信号接收质量为各个GSM小区生成如下表1的上、下行电平值与上、下行信号接收质量值之间的对应关系表。Further, the BSC of the GSM cell will pre-collect the uplink and downlink level values and Uplink and downlink signal reception quality, and when BSC collects the uplink and downlink level values and uplink and downlink signal reception quality of each GSM cell, it will set up a UE for data collection, and the UE will perform the downlink level and downlink level of each GSM cell The measurement and reporting of signal reception quality, and the uplink level and uplink signal reception quality of each GSM cell are measured and reported by BTS (Base Transceiver Station, base transceiver station). Afterwards, the BSC can generate the corresponding relationship between the uplink and downlink level values and the uplink and downlink signal reception quality values in Table 1 for each GSM cell according to the uplink and downlink level values and the uplink and downlink signal reception quality values of each GSM cell .
表1Table 1
其中，上述电平值及信号接收质量值均为统计数值，且均为功控补偿后的数值。Wherein, the above-mentioned level values and signal reception quality values are statistical values, and are values after power control compensation.
进一步地，上下行信号接收质量除了以表1的形式进行表征外，还可以HQI(HighQuality Identity，高质量标识)表征，其中，上行HQI＝(上行信号接收质量0的次数+上行信号接收质量1的次数+上行信号接收质量2的次数+上行信号接收质量3的次数)/上行信号接收质量0～7的总次数*100％，即上行信号接收质量0～3所占的比例；下行HQI＝(下行信号接收质量0的次数+下行信号接收质量1的次数+下行信号接收质量2的次数+下行信号接收质量3的次数)/下行信号接收质量0～7的总次数*100％，即下行信号接收质量0～3所占的比例；若以HQI表征上下行信号接收质量，则上表1可替换为下表2。Further, in addition to being characterized in the form of Table 1, the reception quality of uplink and downlink signals can also be characterized by HQI (HighQuality Identity, high-quality identification), wherein, the uplink HQI=(number of times of uplink signal reception quality 0+uplink signal reception quality 1 The number of times + the number of uplink signal reception quality 2 + the number of uplink signal reception quality 3) / the total number of uplink signal reception quality 0 to 7 * 100%, that is, the proportion of uplink signal reception quality 0 to 3; downlink HQI = (Numbers of downlink signal reception quality 0 + times of downlink signal reception quality 1 + times of downlink signal reception quality 2 + times of downlink signal reception quality 3) / total number of times of downlink signal reception quality 0 to 7 * 100%, namely downlink The ratio of signal reception quality 0 to 3; if HQI is used to characterize the reception quality of uplink and downlink signals, the above table 1 can be replaced with the following table 2.
表2Table 2
其中，上述电平值及上下行HQI均为统计数值，且均为功控补偿后的数值。Wherein, the above-mentioned level values and uplink and downlink HQI are statistical values, and both are values after power control compensation.
需要说明的是，GSM小区的BSC在向UMTS小区的RNC发送其上、下行电平值与上、下行信号接收质量值之间的对应关系表时，既可采用上述表1的形式也可采用上述表2的形式，具体采用哪种形式本实施例对此不作限定。It should be noted that, when the BSC of the GSM cell sends the correspondence table between the uplink and downlink level values and the uplink and downlink signal reception quality values to the RNC of the UMTS cell, the form of the above Table 1 can also be used. The form of the above Table 2, which form is used specifically, is not limited in this embodiment.
此外，由于UMTS小区与GSM小区属于不同通信网络，不能直接进行通信，所以BSC在发送其上、下行电平值与上、下行信号接收质量值之间的对应关系表时，需通过集中控制网元传递该上、下行电平值与上、下行信号接收质量值之间的对应关系表。其中，集中控制网元与UMTS小区的RNC及GSM小区的BSC均存在通信关系。BSC在发送其上、下行电平值与上、下行信号接收质量值之间的对应关系表时，先将该对应关系表发送给集中控制网元，再由集中控制网元将该对应关系表传递给RNC，RNC在得到该对应关系表后，便可继续执行后续处理流程。In addition, since the UMTS cell and the GSM cell belong to different communication networks and cannot communicate directly, the BSC needs to pass the centralized control network The unit transmits the correspondence table between the uplink and downlink level values and the uplink and downlink signal receiving quality values. Wherein, the centralized control network element has a communication relationship with both the RNC of the UMTS cell and the BSC of the GSM cell. When the BSC sends the corresponding relationship table between its uplink and downlink level values and uplink and downlink signal reception quality values, it first sends the corresponding relationship table to the centralized control network element, and then the centralized control network element sends the corresponding relationship table Pass it to the RNC, and after the RNC obtains the correspondence table, it can continue to execute the follow-up processing procedure.
203：RNC根据各个GSM小区的下行电平值查询各个GSM小区的上、下行电平值与上、下行信号接收质量值之间的对应关系表获取各个GSM小区的上行电平值及上、下行信号接收质量值；203: The RNC queries the correspondence table between the uplink and downlink level values of each GSM cell and the uplink and downlink signal reception quality values of each GSM cell according to the downlink level value of each GSM cell, and obtains the uplink level value and uplink and downlink level values of each GSM cell Signal reception quality value;
以获取到的某一GSM小区的下行电平值为-99分贝毫伏为例，则RNC在获取到该下行电平的数值后，便可根据该数值查询如上述步骤202中表1所示的GSM小区的上行电平值、上、下行电平值与上、下行信号接收质量值之间的对应关系表，以获取GSM小区的上行电平值、上、下行电平值对应的上、下行信号接收质量值。若信号接收质量采用上述表1的表征形式，则由表1可知，与下行电平值-99分贝毫伏对应的上行电平值为-107分贝毫伏，与上行电平值-107分贝毫伏对应的上行信号接收质量值为4.8，与下行电平值-99分贝毫伏对应的下行信号接收质量值为4.8，从而根据下行电平值得到上行电平值及上、下行信号接收质量值；Taking the obtained downlink level value of a certain GSM cell as an example of -99 decibel millivolts, after the RNC obtains the value of the downlink level, it can query according to the value as shown in Table 1 in the above step 202 Correspondence table between the uplink level value, uplink and downlink level value and uplink and downlink signal receiving quality value of the GSM cell, so as to obtain the uplink level value, uplink and downlink level value corresponding uplink and downlink level values of the GSM cell, Downlink signal reception quality value. If the signal reception quality adopts the characterization form of Table 1 above, it can be seen from Table 1 that the uplink level value corresponding to the downlink level value -99 decibels millivolts is -107 decibels millivolts, and the uplink level value -107 decibels millivolts corresponds to -107 decibels millivolts. The uplink signal reception quality value corresponding to volts is 4.8, and the downlink signal reception quality value corresponding to the downlink level value -99 decibels millivolts is 4.8, so that the uplink level value and the uplink and downlink signal reception quality values are obtained according to the downlink level value ;
此外，若信号接收质量采用上述表2的表征形式，则在获取到下行电平的数值后，便可根据该数值查询如上述步骤202中表2所示的GSM小区的上、下行电平值与上、下行信号接收质量值之间的对应关系表，以获取GSM小区的上行电平值、上、下行电平值对应的上、下行信号接收质量值。由表2可知，与下行电平值-99分贝毫伏对应的上行电平值为-107分贝毫伏，与上行电平值-107分贝毫伏对应的上行信号接收质量值为93％，与下行电平值-99分贝毫伏对应的下行信号接收质量值为93％，从而根据上、下行电平值得到上、下行信号接收质量值；In addition, if the signal reception quality adopts the characterization form of the above-mentioned Table 2, after the value of the downlink level is obtained, the uplink and downlink level values of the GSM cell as shown in Table 2 in the above step 202 can be queried according to the value Correspondence table with uplink and downlink signal reception quality values to obtain uplink and downlink signal reception quality values corresponding to the uplink level value and uplink and downlink level values of the GSM cell. It can be seen from Table 2 that the uplink level value corresponding to the downlink level value -99 decibel millivolts is -107 decibels millivolts, and the uplink signal reception quality value corresponding to the uplink level value -107 decibels millivolts is 93%, which is the same as The downlink signal reception quality value corresponding to the downlink level value -99 decibels millivolts is 93%, so that the uplink and downlink signal reception quality values are obtained according to the uplink and downlink level values;
204：RNC根据各个GSM小区的上、下行电平值及上、下行信号接收质量值进行切换判决；204: The RNC performs handover judgment according to the uplink and downlink level values and uplink and downlink signal reception quality values of each GSM cell;
针对该步骤，RNC根据各个GSM小区的上、下行电平值及上、下行信号接收质量值进行切换判决，包括但不限于如下方式：For this step, the RNC performs handover decisions according to the uplink and downlink level values and uplink and downlink signal reception quality values of each GSM cell, including but not limited to the following methods:
当RNC判断出任一GSM小区的上、下行电平值均高于第一预设门限且上、下行信号接收质量值均低于第二预设门限时，判断该任一GSM小区的上、下行电平值及上、下行信号接收质量值满足切换判决条件。When the RNC judges that the uplink and downlink level values of any GSM cell are higher than the first preset threshold and the uplink and downlink signal reception quality values are lower than the second preset threshold, judge the uplink and downlink of the any GSM cell The level value and uplink and downlink signal reception quality values meet the handover decision conditions.
其中，第一预设门限具体可为-65分贝毫伏，当然，第一预设门限的大小除上述数值外，还可为其他数值，例如，-70或-75分贝毫伏，本实施例对第一预设门限的大小不进行具体限定；第二预设门限的大小依据信号接收质量的表征形式而定，若信号接收质量直接以上述步骤202中表1的形式表征，则第二预设门限的大小具体可为4.5，当然第二预设门限的大小除上述数值外，还可为其他数值，例如，4或5，本实施例对第二预设门限的大小同样不进行具体限定；若信号接收质量以上述步骤202中表2的形式表征，则第二预设门限的大小具体可为80％，当然第二预设门限的大小除上述数值外，还可为其他数值，例如，85％或90％，本实施例对第二预设门限的大小不进行具体限定。Wherein, the first preset threshold may specifically be -65 decibel millivolts. Of course, the size of the first preset threshold may be other values besides the above-mentioned values, for example, -70 or -75 decibels millivolts. In this embodiment The size of the first preset threshold is not specifically limited; the size of the second preset threshold depends on the characterization form of the signal reception quality, if the signal reception quality is directly characterized by the form of Table 1 in the above step 202, then the second preset threshold The size of the threshold can be specifically 4.5. Of course, the size of the second preset threshold can also be other values, such as 4 or 5, in addition to the above-mentioned values. This embodiment does not specifically limit the size of the second preset threshold. If the quality of signal reception is characterized by the form of Table 2 in the above-mentioned step 202, the size of the second preset threshold can be specifically 80%, and of course the size of the second preset threshold can also be other values besides the above-mentioned values, for example , 85% or 90%, the size of the second preset threshold is not specifically limited in this embodiment.
205：如果任一GSM小区的上、下行电平值及上、下行信号接收质量值满足切换判决条件，则RNC向UE下发切换命令，以控制UE切换至该任一GSM小区。205: If the uplink and downlink level values and uplink and downlink signal reception quality values of any GSM cell meet the handover decision condition, the RNC sends a handover command to the UE to control the UE to handover to the any GSM cell.
其中，在判断该任一GSM小区满足切换判决条件后，便通过空中接口向UE下发切换命令，UE在收到切换命令后，便从UMTS小区切换至该任一GSM小区，进而保证了通信的连续性。Wherein, after judging that any GSM cell satisfies the handover decision condition, a handover command is issued to the UE through the air interface, and after receiving the handover command, the UE switches from the UMTS cell to the any GSM cell, thereby ensuring communication continuity.
此外，针对存在多个GSM小区的上、下行电平值及上、下行信号接收质量值同时满足切换判决条件时的情况，本实施例提供的方法还包括：选择上、下行电平值最优或上、下行信号接收质量值最优或上、下行电平值及上、下行信号接收质量值均最优的GSM小区作为UE的切换小区，并控制UE切换至该小区。其中，上、下行电平值最优指代上、下行电平值最大，上、下行信号接收质量值最优指代上、下行信号接收质量值最小。例如，若3个GSM小区均满足切换判决条件，以符号GSM1、GSM2及GSM3对3个GSM小区进行标识，GSM1的上、下行电平值为-85分贝毫伏及-88分贝毫伏，上、下行信号接收质量值为4及5，GSM2的上、下行电平值为-80分贝毫伏及-85分贝毫伏，上、下行信号接收质量值为3及4，GSM3的上、下行电平值为-75分贝毫伏及-80分贝毫伏，上、下行信号接收质量值为2及3为例，且若以上、下行电平值最优作为选择标准，则选择GSM3小区作为UE的目标切换小区。In addition, for the situation that the uplink and downlink level values and uplink and downlink signal reception quality values of multiple GSM cells meet the handover decision conditions at the same time, the method provided by this embodiment further includes: selecting the best uplink and downlink level values Or the GSM cell with the best uplink and downlink signal reception quality values or the best uplink and downlink signal level values and uplink and downlink signal reception quality values is used as the handover cell of the UE, and the UE is controlled to handover to this cell. Wherein, the optimal uplink and downlink level values refer to the maximum uplink and downlink level values, and the optimal uplink and downlink signal reception quality values refer to the minimum uplink and downlink signal reception quality values. For example, if all three GSM cells meet the handover decision conditions, the three GSM cells are marked with symbols GSM1, GSM2, and GSM3, and the uplink and downlink levels of GSM1 are -85 dBmV and -88 dBmV, and the uplink , Downlink signal receiving quality values are 4 and 5, GSM2 uplink and downlink level values are -80dBmV and -85dBmV, uplink and downlink signal receiving quality values are 3 and 4, GSM3 uplink and downlink level values The average value is -75dBmV and -80dBmV, and the uplink and downlink signal reception quality values are 2 and 3 as an example, and if the above and downlink level values are the best as the selection criteria, then select the GSM3 cell as the UE Target handover cell.
下面结合一个具体的例子对上述步骤201至步骤205提供的切换判决方法进行详细地解释说明。The handover decision method provided in the above step 201 to step 205 will be explained in detail below in conjunction with a specific example.
以某一UE当前处于通话状态，且处于UMTS小区边缘为例，则为了保证该UE的通信连续性，需要进行小区切换。假设与该UMTS小区邻近的GSM小区有2个,分别以符号G1和G2进行标识，且统一由BSC1进行控制，则在进行切换判决之前，BSC1便已为各个GSM小区生成了对应的上、下行电平值与上、下行信号接收质量值之间的对应关系表，并存放于自身中。当RNC在进行切换判决时，首先会经由集中控制网元获取存储在BSC1中的2个GSM小区的上、下行电平值与上、下行信号接收质量值之间的对应关系表，并根据待切换UE上报的各个GSM小区的下行电平值，查询对应的上、下行电平值与上、下行信号接收质量值之间的对应关系表，得到各个GSM小区的上行电平值及上下行信号接收质量。Taking a UE that is currently in a call state and is at the edge of a UMTS cell as an example, in order to ensure the communication continuity of the UE, cell handover is required. Assuming that there are two GSM cells adjacent to the UMTS cell, which are marked with symbols G1 and G2 respectively, and are uniformly controlled by BSC1, then BSC1 has generated corresponding uplink and downlink for each GSM cell before making a handover decision. The correspondence table between the level value and the receiving quality value of the uplink and downlink signals is stored in itself. When the RNC is making a handover decision, it first obtains the correspondence table between the uplink and downlink level values and the uplink and downlink signal reception quality values of the two GSM cells stored in BSC1 through the centralized control network element, and according to the Switch the downlink level value of each GSM cell reported by the UE, query the correspondence table between the corresponding uplink and downlink level values and the uplink and downlink signal reception quality values, and obtain the uplink level value and uplink and downlink signal of each GSM cell Receive quality.
假设待切换UE上报了G1和G2的下行电平，且G1的下行电平值为-70分贝毫伏,G2的下行电平值为-80分贝毫伏。之后，RNC根据二者的下行电平值分别查询G1和G2的上、下行电平值与上、下行信号接收质量值之间的对应关系表，并得到G1的上行电平值为-82分贝毫伏，下行信号接收质量为5，上行信号接收质量为6；G2小区的上行电平值为-88分贝毫伏，下行信号接收质量为2，上行质量为1，以第一预设门限为-85分贝毫伏，第二预设门限为4为例，则由于G1的上下行信号接收质量不满足预设门限，因此不会选择G1作为待切换UE的目标切换小区，而选择G2作为待切换UE在UMTS小区边缘处的目标切换小区。Assume that the UE to be handed over reports the downlink levels of G1 and G2, and the downlink level value of G1 is -70 decibel millivolts, and the downlink level value of G2 is -80 decibels millivolts. Afterwards, the RNC respectively inquires the correspondence table between the uplink and downlink level values of G1 and G2 and the received quality values of the uplink and downlink signals according to the downlink level values of the two, and obtains the uplink level value of G1 as -82 decibels Millivolts, downlink signal reception quality is 5, uplink signal reception quality is 6; G2 cell's uplink level value is -88dB millivolts, downlink signal reception quality is 2, uplink quality is 1, the first preset threshold is -85dBmV, and the second preset threshold is 4 as an example, since the uplink and downlink signal reception quality of G1 does not meet the preset threshold, G1 will not be selected as the target handover cell of the UE to be handed over, and G2 will be selected as the target handover cell of the UE to be handed over. Handover the target handover cell of the UE at the edge of the UMTS cell.
此外，UE当前所在的小区除本实施例示出的UMTS小区外，还可为LTE小区、GSM小区、TD-SCDMA(Time Division-Synchronous Code Division Multiple Access，时分同步码分多址)小区、CDMA(Code Division Multiple Access，码分多址)小区、Wimax(Worldwide Interoperability for Microwave Access，微波存取全球互通)小区；UE待切换的小区除本实施例示出的GSM小区外，还可以为LTE小区、UMTS小区、TD-SCDMA小区、CDMA小区、Wimax小区；即本实施例提供的小区切换的控制方法，既可实现不同通信网络间的切换，也可实现同一通信网络间的切换。而无论UE由哪个小区切换至另一小区，切换判决方式均与上述步骤201至步骤205的切换判决方式一致，此处不再赘述。例如，当UE由LTE小区切换至GSM小区或由TD-SCDMA小区切换至GSM小区时，LTE小区的控制器或TD-SCDMA小区的控制器在进行切换判决时，其切换判决方式均可采用上述步骤201至步骤205的RNC进行切换判决的方式。In addition, in addition to the UMTS cell shown in this embodiment, the cell where the UE currently resides may also be an LTE cell, a GSM cell, a TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) cell, a CDMA ( Code Division Multiple Access, code division multiple access) cell, Wimax (Worldwide Interoperability for Microwave Access, microwave access global interoperability) cell; the cell to be handed over by UE can also be LTE cell, UMTS cell, in addition to the GSM cell shown in this embodiment A cell, a TD-SCDMA cell, a CDMA cell, and a Wimax cell; that is, the cell switching control method provided in this embodiment can realize switching between different communication networks and switching between the same communication network. No matter from which cell the UE is handed over to another cell, the handover decision method is the same as the handover decision method in steps 201 to 205 above, and will not be repeated here. For example, when the UE is handed over from an LTE cell to a GSM cell or from a TD-SCDMA cell to a GSM cell, when the controller of the LTE cell or the controller of the TD-SCDMA cell makes a handover decision, the handover decision method can use the above The manner in which the RNC performs handover decision in steps 201 to 205.
需要说明的是，UE待切换小区的控制器在发送其上、下行电平值与上、下行信号接收质量值之间的对应关系表至集中控制网元后，集中控制网元可不将该对应关系转发至UE当前所在小区的控制器，而直接根据该对应关系表及上、下行电平值进行切换判决，且集中控制网元在进行切换判决时，其切换判决方式同上述步骤201至步骤205的RNC进行切换判决的方式一致，在得到判决结果后，再将判决结果发送给UE当前所在小区的控制器。It should be noted that after the controller of the cell to be handed over by the UE sends the correspondence table between its uplink and downlink level values and uplink and downlink signal reception quality values to the centralized control network element, the centralized control network element may not The relationship is forwarded to the controller of the cell where the UE is currently located, and the handover decision is made directly according to the corresponding relationship table and the uplink and downlink level values, and when the centralized control network element makes a handover decision, the handover decision method is the same as the above steps 201 to The RNC in 205 performs handover judgment in the same way, and after obtaining the judgment result, it sends the judgment result to the controller of the cell where the UE is currently located.
本实施例提供的方法，在获取待切换小区的上、下行电平值及上下行信号质量值后，根据上、下行电平值及上、下行信号接收质量值进行切换判决，因此，判决方式更加严谨，提高了小区切换的成功率，且在判断任一待切换小区的上、下行电平值及上、下行信号接收质量值满足切换判决条件后，下发切换命令控制UE切换至该待切换小区，从而保证了通信的连续性。In the method provided by this embodiment, after acquiring the uplink and downlink level values and the uplink and downlink signal quality values of the cell to be switched, the handover decision is made according to the uplink and downlink level values and the uplink and downlink signal reception quality values. Therefore, the judgment method It is more rigorous and improves the success rate of cell handover. After judging that the uplink and downlink level values and uplink and downlink signal reception quality values of any cell to be handed over meet the handover judgment conditions, a handover command is issued to control the UE to switch to the waiting cell. Cell switching ensures the continuity of communication.
