技术领域Technical Field
本公开涉及通信技术领域,尤其涉及避开问题小区的方法和相关产品。The present disclosure relates to the field of communication technology, and in particular to a method for avoiding problem cells and related products.
背景技术Background Art
随着蜂窝网络从2G演进到现在的5G,总有一些覆盖特定区域的位置或小区可能会由于网络错误配置或网络问题等与用户设备(user equipment,UE)无关的原因,导致UE的各种通信问题,例如数据停滞、无服务、掉话等。这种情况更多发生在从旧一代网络向新一代网络演进的过程中,例如目前从4G到5G演进的过程中。As cellular networks evolve from 2G to the current 5G, there are always some locations or cells covering a specific area that may cause various communication problems for user equipment (UE), such as data stagnation, no service, and dropped calls, due to network misconfiguration or network problems that are unrelated to the user equipment (UE). This situation occurs more often in the process of evolving from an old generation of networks to a new generation of networks, such as the current evolution from 4G to 5G.
UE可以通过一些方法从这种情况中恢复,例如重试或飞行模式开-关重置。但是,如果UE返回相同的地点,因为UE可能会驻留在同一个问题小区,则可能会再次发生类似的通信问题。如何降低驻留到问题小区的可能性甚至完全避开那些小区一直是有待解决的问题。The UE can recover from this situation through some methods, such as retry or airplane mode on-off reset. However, if the UE returns to the same place, similar communication problems may occur again because the UE may camp on the same problem cell. How to reduce the possibility of camping on problem cells or even avoid those cells completely has always been an unsolved problem.

在下文中,将给出本公开的实施方式的详细描述。Hereinafter, a detailed description will be given of embodiments of the present disclosure.
图1是根据实施方式的避开问题小区的方法的流程示意图。如图1所示,避开问题小区的方法包括以下内容。Fig. 1 is a schematic flow chart of a method for avoiding problem cells according to an embodiment. As shown in Fig. 1 , the method for avoiding problem cells includes the following contents.
在框102,响应于检测到满足条件,将UE驻留的第一小区的信息添加到列表,其中,该列表用于UE选择小区。At block 102, in response to detecting that a condition is met, information of a first cell where the UE is camped is added to a list, wherein the list is used for the UE to select a cell.
第一小区的信息包括以下至少一项:公共陆地移动网络(public land mobilenetwork,PLMN)相关信息、跟踪区码(tracking area code,TAC)、小区频率、物理小区标识(physical cell identity,PCI)、全球小区标识(global cell identity,GCI)、将第一小区的信息添加到列表的时间、第一定时器的时长、以及至少一个异常事件发生的次数。The information of the first cell includes at least one of the following: public land mobile network (PLMN) related information, tracking area code (TAC), cell frequency, physical cell identity (PCI), global cell identity (GCI), the time when the information of the first cell is added to the list, the duration of the first timer, and the number of times at least one abnormal event occurs.
当前列表可以包括去优先化列表和黑名单之一。在本公开的实施方式中,响应于检测到满足条件,UE驻留的第一小区的信息被添加到列表,其中,该列表用于UE选择小区。因此,借助于该列表,在驻留到可能是问题小区的小区之前,UE可以根据列表选择小区。这样,当UE回到问题小区时,可以降低驻留到问题小区的可能性,甚至可以避免那些问题小区。The current list may include one of a deprioritization list and a blacklist. In an embodiment of the present disclosure, in response to detecting that a condition is met, information of the first cell where the UE resides is added to a list, wherein the list is used for the UE to select a cell. Therefore, with the help of the list, before residing in a cell that may be a problem cell, the UE can select a cell according to the list. In this way, when the UE returns to the problem cell, the possibility of residing in the problem cell can be reduced, and those problem cells can even be avoided.
作为实施方式,检测到满足条件包括检测到第一小区发生至少一个异常事件。As an implementation manner, detecting that the condition is met includes detecting that at least one abnormal event occurs in the first cell.
异常事件可以包括以下至少一项:UE空闲模式故障、UE服务相关故障、和UE服务性能相关故障,其中,UE服务包括以下至少一项:语音呼叫、数据呼叫、短消息服务(shortmessage service,SMS)、和补充服务,UE服务性能包括以下至少一项:语音质量和吞吐量。Abnormal events may include at least one of the following: UE idle mode failure, UE service-related failure, and UE service performance-related failure, wherein UE service includes at least one of the following: voice call, data call, short message service (SMS), and supplementary service, and UE service performance includes at least one of the following: voice quality and throughput.
作为实施方式,检测到满足条件包括以下内容。As an embodiment, detecting that the condition is satisfied includes the following.
检测到第一小区发生至少一个异常事件。确定至少一个异常事件发生的次数。检测到至少一个异常事件发生的次数大于阈值。At least one abnormal event is detected to occur in the first cell. The number of times the at least one abnormal event occurs is determined. The number of times the at least one abnormal event occurs is detected to be greater than a threshold.
作为实施方式,上述列表包括去优先级列表和黑名单,并且响应于检测到满足条件,将UE驻留的第一小区的信息添加到列表包括以下内容。As an implementation manner, the above-mentioned list includes a deprioritization list and a blacklist, and in response to detecting that a condition is satisfied, adding information of the first cell where the UE camps on to the list includes the following contents.
当至少一个异常事件发生的次数大于第一阈值时,将第一小区的信息添加到去优先级列表。当上述次数大于第二阈值时,将第一小区的信息添加到黑名单,第二阈值大于第一阈值。When the number of occurrences of at least one abnormal event is greater than a first threshold, the information of the first cell is added to the deprioritization list. When the number of occurrences of at least one abnormal event is greater than a second threshold, the information of the first cell is added to the blacklist, and the second threshold is greater than the first threshold.
作为实施方式,上述列表包括去优先级列表和黑名单,并且响应于检测到满足条件,将UE驻留的第一小区的信息添加到列表包括以下内容。As an implementation manner, the above-mentioned list includes a deprioritization list and a blacklist, and in response to detecting that a condition is satisfied, adding information of the first cell where the UE camps on to the list includes the following contents.
当上述次数大于第一阈值且小于第二阈值时,将第一小区的信息添加到去优先级列表。第一小区的信息包括以下至少一项:PLMN相关信息、TAC、小区频率、PCI、GCI、将第一小区的信息添加到去优先级列表的时间、第一定时器的时长Tdepri、以及至少一个异常事件发生的次数。When the number is greater than a first threshold and less than a second threshold, the information of the first cell is added to the deprioritization list. The information of the first cell includes at least one of the following: PLMN related information, TAC, cell frequency, PCI, GCI, the time when the information of the first cell is added to the deprioritization list, the duration T depri of the first timer, and the number of times at least one abnormal event occurs.
当上述次数大于第二阈值时,从去优先级列表中移除第一小区的信息,并将第一小区的信息添加到黑名单。第一小区的信息包括以下至少一项:PLMN相关信息、TAC、小区频率、PCI、GCI、将第一小区的信息添加到黑名单的时间、第一定时器的时长Tblacklist、以及至少一个异常事件发生的次数。When the number of times is greater than a second threshold, the information of the first cell is removed from the deprioritization list, and the information of the first cell is added to a blacklist. The information of the first cell includes at least one of the following: PLMN related information, TAC, cell frequency, PCI, GCI, time when the information of the first cell is added to the blacklist, duration T blacklist of the first timer, and number of times at least one abnormal event occurs.
为了避免随机问题可能导致正常小区被去优先级或被加入黑名单的情况,使用计数器Cab来记录第一小区发生至少一个异常事件的次数。当该小区中至少一个异常事件发生的次数大于预定义第一阈值Thab-dep(用于去优先级的阈值,例如为2)或Thab-bl(用于黑名单的阈值,例如为4)时,将考虑下一动作,即将第一小区去优先级或加入黑名单。具体地,UE可以基于Cab的值决定下一动作(将第一小区去优先级或加入黑名单),如果Cab的值大于Thab-dep但小于Thab-bl,则考虑将第一小区去优先级,去优先级的动作不那么激进,否则如果Cab的值大于Thab-bl,则考虑将第一小区加入黑名单。In order to avoid the situation where a normal cell may be deprioritized or added to a blacklist due to random problems, a counter Cab is used to record the number of times at least one abnormal event occurs in the first cell. When the number of times at least one abnormal event occurs in the cell is greater than a predefined first threshold value Thab-dep (a threshold value for deprioritization, for example, 2) or Thab -bl (a threshold value for blacklisting, for example, 4), the next action will be considered, that is, deprioritizing or adding the first cell to a blacklist. Specifically, the UE may determine the next action (deprioritizing or adding the first cell to a blacklist) based on the value of Cab . If the value of Cab is greater than Thab -dep but less than Thab-bl , deprioritizing the first cell is considered, and the deprioritization action is not so aggressive. Otherwise, if the value of Cab is greater than Thab-bl , adding the first cell to a blacklist is considered.
为了降低UE再次驻留第一小区的可能性或者甚至避免UE再次驻留第一小区,第一层动作是将第一小区去优先级,这可以包括将第一小区的信息添加到去优先级列表,从而第一小区被去优先级。第二层动作是将第一小区加入黑名单,这可以包括将第一小区的信息添加到黑名单列表,从而第一小区被加入黑名单。关于如何对第一小区进行去优先级或者加入黑名单的操作,也可以参考下文中将第一小区的信息加入去优先级列表或黑名单后的操作的描述。通过第一层动作,可以降低第一小区的小区选择优先级,并降低UE驻留在第一小区的可能性。通过第二层动作,将使UE不会驻留或切换到第一小区。In order to reduce the possibility of the UE re-residence in the first cell or even avoid the UE re-residence in the first cell, the first layer action is to deprioritize the first cell, which may include adding the information of the first cell to a deprioritization list, so that the first cell is deprioritized. The second layer action is to add the first cell to a blacklist, which may include adding the information of the first cell to a blacklist, so that the first cell is added to the blacklist. For how to deprioritize or blacklist the first cell, refer to the description of the operation after adding the information of the first cell to the deprioritization list or blacklist below. Through the first layer action, the cell selection priority of the first cell can be reduced, and the possibility of the UE residing in the first cell can be reduced. Through the second layer action, the UE will not reside in or switch to the first cell.
因此,当UE第一次驻留到第一小区时,如果UE检测到第一小区是问题小区,则可以将第一小区的信息添加到去优先级列表或黑名单。当UE返回第一小区所在的相同地点时,在驻留到UE可以从其接收到信号的第一小区之前,UE可以检测去优先级列表或黑名单中是否存在第一小区的信息。当去优先级列表或黑名单中存在第一小区的信息时,UE可以选择另一小区,而不驻留到有问题的第一小区。由此,当UE回到问题小区时,可以降低驻留到问题小区的可能性,或者甚至可以避免这些问题小区。Therefore, when the UE camps on the first cell for the first time, if the UE detects that the first cell is a problem cell, the information of the first cell can be added to the deprioritization list or blacklist. When the UE returns to the same location where the first cell is located, before camping on the first cell from which the UE can receive a signal, the UE can detect whether the information of the first cell is in the deprioritization list or blacklist. When the information of the first cell exists in the deprioritization list or blacklist, the UE can select another cell instead of camping on the problematic first cell. Thus, when the UE returns to the problem cell, the possibility of camping on the problem cell can be reduced, or even these problem cells can be avoided.
作为实施方式,异常事件包括以下至少一项:UE空闲模式故障、UE服务相关故障、和UE服务性能相关故障,其中,UE服务包括以下至少一项:语音呼叫、数据呼叫、SMS、和补充服务,UE服务性能包括以下至少一项:语音质量和吞吐量。As an implementation method, the abnormal event includes at least one of the following: UE idle mode failure, UE service-related failure, and UE service performance-related failure, wherein the UE service includes at least one of the following: voice call, data call, SMS, and supplementary service, and the UE service performance includes at least one of the following: voice quality and throughput.
UE空闲模式故障可以包括以下至少一种:停止服务、服务受限、长期演进语音(Voice over long-term evolution,VoLTE)/新空口语音(Voice over new radio,VoNR)未注册、频繁服务拒绝、频繁服务丢失。UE服务相关故障可以包括以下至少一项的故障:语音呼叫(例如电路交换(circuit switching,CS)、IP多媒体子系统(IP MultimediaSubsystem,IMS)、电路交换回退(circuit switched fallback,CSFB))、数据呼叫、SMS和补充服务。数据呼叫失败可能包括无数据或数据服务不可用。SMS或补充服务的失败可以包括通过信令或IMS的SMS或补充服务的失败。UE服务性能相关故障可以包括语音质量差(如CS、VoLTE、VoNR)和低吞吐量等。UE idle mode failures may include at least one of the following: out of service, limited service, Voice over long-term evolution (VoLTE)/Voice over new radio (VoNR) unregistered, frequent service rejection, frequent service loss. UE service-related failures may include at least one of the following failures: voice calls (e.g., circuit switching (CS), IP Multimedia Subsystem (IMS), circuit switched fallback (CSFB)), data calls, SMS, and supplementary services. Data call failures may include no data or data service unavailable. Failures of SMS or supplementary services may include failures of SMS or supplementary services through signaling or IMS. UE service performance-related failures may include poor voice quality (e.g., CS, VoLTE, VoNR) and low throughput, etc.
作为实施方式,当第一小区的信息被添加到去优先级列表或黑名单时,启动第一定时器。检测到第一定时器到期时,从去优先级列表或黑名单中移除第一小区的信息。第一定时器的时长基于至少一个异常事件发生的次数。As an implementation method, when the information of the first cell is added to the deprioritization list or blacklist, a first timer is started. When the expiration of the first timer is detected, the information of the first cell is removed from the deprioritization list or blacklist. The duration of the first timer is based on the number of times at least one abnormal event occurs.
不管是将小区去优先级还是将小区加入黑名单,UE都可以用第一定时器控制将小区去优先级或者加入黑名单的时长。定时器的时长可以基于计数器的值Cab设置。计算器的值越大,对应的第一定时器时长越长。Regardless of whether the cell is deprioritized or added to the blacklist, the UE can use the first timer to control the duration of deprioritizing or adding the cell to the blacklist. The duration of the timer can be set based on the value of the counter C ab . The larger the value of the counter, the longer the corresponding first timer duration.
具体地,在第一小区的信息被添加到去优先级列表Listdepri后,即使UE断电,第一小区的信息也会保留在该去优先级列表中,从而记住该问题小区,直到第一定时器到期。当第一定时器Tdepri到期时,UE将从去优先级列表Listdepri中移除第一小区的信息,并重置第一小区的所有数据。当第一小区的信息被添加到黑名单Listblacklist时,即使UE断电,第一小区的信息也会保留在该黑名单中,从而记住该问题小区,直到第一定时器到期。当第一定时器Tblacklist到期时,UE将从黑名单Listblacklist中移除第一小区的信息。Specifically, after the information of the first cell is added to the deprioritization list List depri , even if the UE is powered off, the information of the first cell will remain in the deprioritization list, thereby remembering the problem cell until the first timer expires. When the first timer T depri expires, the UE will remove the information of the first cell from the deprioritization list List depri and reset all data of the first cell. When the information of the first cell is added to the blacklist List blacklist , even if the UE is powered off, the information of the first cell will remain in the blacklist, thereby remembering the problem cell until the first timer expires. When the first timer T blacklist expires, the UE will remove the information of the first cell from the blacklist List blacklist .
作为实施方式,在第一小区的信息被添加到黑名单后,确定在监控周期内第一小区的信息被添加到黑名单的次数。根据第一小区的信息被添加到黑名单的所述次数,更新第一定时器的时长。As an implementation, after the information of the first cell is added to the blacklist, the number of times the information of the first cell is added to the blacklist within the monitoring period is determined. According to the number of times the information of the first cell is added to the blacklist, the duration of the first timer is updated.
具体地,Tblacklist的值将基于监控周期Tmon内小区曾被添加到Listblacklist的次数,Tmon可以是一段长的时间,例如数天或数周。如果在监控周期Tmon内,该小区曾被添加到黑名单N次,则下一次第一小区的信息被添加到Listblacklist,Tblacklist的值将是(2N+1)*基值(基值待定义)。这可以进一步确保问题小区被加入黑名单较长的时间。当过了Tmon后,将重置所有小区数据。Specifically, the value of T blacklist will be based on the number of times the cell has been added to List blacklist within the monitoring period T mon , which can be a long period of time, such as days or weeks. If the cell has been added to the blacklist N times within the monitoring period T mon , the next time the information of the first cell is added to List blacklist , the value of T blacklist will be (2N+1)*base value (base value to be defined). This can further ensure that the problem cell is added to the blacklist for a longer period of time. After T mon has passed, all cell data will be reset.
作为实施方式,在将第一小区的信息添加到去优先级列表之前,确定去优先级列表中是否存在第一小区的信息。检测到去优先级列表中存在第一小区的信息时,从去优先级列表中移除第一小区的信息,并将第一小区的信息添加到黑名单。As an implementation, before adding the information of the first cell to the deprioritization list, determine whether the information of the first cell exists in the deprioritization list. When detecting that the information of the first cell exists in the deprioritization list, remove the information of the first cell from the deprioritization list and add the information of the first cell to the blacklist.
作为实施方式,在检测到第一小区发生至少一个异常事件之前,UE还检测到第一小区的信号强度大于第三阈值。As an implementation manner, before detecting that at least one abnormal event occurs in the first cell, the UE further detects that the signal strength of the first cell is greater than a third threshold.
通过在检测到第一小区发生至少一个异常事件之前检测到第一小区的信号强度大于第三阈值,可以排除由于覆盖弱或信号差导致的问题。由诸如覆盖弱或信号差等随机问题导致的通信问题可以通过移动到另一位置来克服,本申请考虑了这一因素。在检测到第一小区的信号强度大于第三阈值后,执行后续操作,例如检测到第一小区发生至少一个异常事件以及确定至少一个异常事件发生的次数。第三阈值可以是静态值或动态值,可以确定第三阈值以真实反映信号水平,当信号强度低于第三阈值时,覆盖较弱。By detecting that the signal strength of the first cell is greater than the third threshold before detecting that at least one abnormal event has occurred in the first cell, problems caused by weak coverage or poor signal can be eliminated. Communication problems caused by random problems such as weak coverage or poor signal can be overcome by moving to another location, and the present application takes this factor into consideration. After detecting that the signal strength of the first cell is greater than the third threshold, subsequent operations are performed, such as detecting that at least one abnormal event has occurred in the first cell and determining the number of times at least one abnormal event has occurred. The third threshold can be a static value or a dynamic value, and the third threshold can be determined to truly reflect the signal level. When the signal strength is lower than the third threshold, the coverage is weak.
作为实施方式,对于第一小区的不同无线接入技术(radio access technology,RAT),不同RAT中的每种RAT对应于一个第三阈值。例如,对于第三小区的不同RAT,第三阈值的值不同。As an implementation manner, for different radio access technologies (RATs) of the first cell, each of the different RATs corresponds to a third threshold. For example, for different RATs of the third cell, the value of the third threshold is different.
对于不同的RAT,例如第二代无线电话技术(2G)、第三代无线电话技术(3G)、第四代移动通信技术(4G)和第五代移动通信技术(5G),第三阈值的值不同。For different RATs, such as the second generation wireless telephone technology (2G), the third generation wireless telephone technology (3G), the fourth generation mobile communication technology (4G) and the fifth generation mobile communication technology (5G), the value of the third threshold is different.
作为实施方式,在将第一小区的信息添加到去优先级列表之后,UE还可以执行以下操作以降低重选到第一小区的可能性。检测到UE处于空闲模式时,将第一小区的选择优先级设置为最低。对与第一小区对应的参考信号接收功率(reference signal receivedpower,RSRP)的实际测量结果应用偏移,以获得处理后的测量结果。基于第一小区的选择优先级和处理后的测量结果选择小区。As an implementation, after adding the information of the first cell to the deprioritization list, the UE may also perform the following operations to reduce the possibility of reselecting to the first cell. When it is detected that the UE is in idle mode, the selection priority of the first cell is set to the lowest. An offset is applied to the actual measurement result of the reference signal received power (RSRP) corresponding to the first cell to obtain a processed measurement result. A cell is selected based on the selection priority of the first cell and the processed measurement result.
具体地,在首次将第一小区的信息添加到去优先级列表Listdepri之后,UE处于空闲模式时,UE将第一小区的选择优先级设置为最低,并应用内部偏移(Offsetidle,负值)以降低与第一小区对应的RSRP的实际测量结果。由此,在空闲模式下的小区测量期间,UE将更有可能改变到不在列表Listdepri中的其他小区。偏移Offsetidle可以是固定值或动态值。Specifically, after the information of the first cell is added to the deprioritization list List depri for the first time, when the UE is in idle mode, the UE sets the selection priority of the first cell to the lowest, and applies an internal offset (Offset idle , a negative value) to reduce the actual measurement result of the RSRP corresponding to the first cell. As a result, during the cell measurement in idle mode, the UE will be more likely to change to other cells that are not in the list List depri . The offset Offset idle can be a fixed value or a dynamic value.
此外,当UE返回第一小区所在的同一地点并且将要驻留到第一小区时,通过去优先级列表或黑名单,可以检测第一小区的信息是否在去优先级列表或黑名单中。在检测到第一小区的信息在去优先级列表中时,除了内部设置(列表中的小区的)小区重选优先级为最低以外,UE还可以对与第一小区对应的RSRP的实际测量结果应用偏移,以获得处理后的测量结果,并且基于处理后的测量结果和小区重选优先级选择小区。In addition, when the UE returns to the same location where the first cell is located and is about to camp on the first cell, it can detect whether the information of the first cell is in the deprioritization list or the blacklist through the deprioritization list or the blacklist. When it is detected that the information of the first cell is in the deprioritization list, in addition to internally setting the cell reselection priority (of the cells in the list) to the lowest, the UE can also apply an offset to the actual measurement result of the RSRP corresponding to the first cell to obtain a processed measurement result, and select a cell based on the processed measurement result and the cell reselection priority.
作为实施方式,在将第一小区的信息添加到去优先级列表之后,UE还可以执行以下操作以降低重选到第一小区的可能性。检测到UE处于无线资源控制(radio resourcecontrol,RRC)连接模式时,对第一小区的参数的实际测量结果应用用于去优先级的偏移,以获得处理后的测量结果,其中,待测量的第一小区的参数由网络配置。将携带处理后的测量结果的测量报告发送到网络,其中,该测量报告用于网络基于处理后的测量结果将UE切换到另一小区。As an implementation, after adding the information of the first cell to the de-prioritization list, the UE may also perform the following operations to reduce the possibility of reselecting to the first cell. When it is detected that the UE is in a radio resource control (RRC) connection mode, an offset for de-prioritization is applied to an actual measurement result of a parameter of the first cell to obtain a processed measurement result, wherein the parameter of the first cell to be measured is configured by the network. A measurement report carrying the processed measurement result is sent to the network, wherein the measurement report is used by the network to switch the UE to another cell based on the processed measurement result.
参考图2,图2是根据实施方式的当UE处于RRC连接模式时在LTE网络中选择另一小区的示意图。具体地,当去优先级列表中存在第一小区的信息并且UE处于RRC连接模式时,UE将用于去优先级的偏移Offsetconn应用于服务小区测量结果(以及列表中的非服务小区)。因此,UE可以触发测量报告事件(在3GPP 36.331(4G)/38.331(5G)规范中定义)并将具有处理后的测量结果的测量报告发送到网络,从而网络可以将UE切换到另一相邻小区。用于去优先级的偏移Offsetconn是负值,可以是固定值或动态值。Referring to Figure 2, Figure 2 is a schematic diagram of selecting another cell in an LTE network when the UE is in RRC connected mode according to an embodiment. Specifically, when there is information of the first cell in the deprioritization list and the UE is in RRC connected mode, the UE applies the offset Offset conn for deprioritization to the serving cell measurement result (and the non-serving cell in the list). Therefore, the UE can trigger a measurement report event (defined in the 3GPP 36.331 (4G) / 38.331 (5G) specification) and send a measurement report with the processed measurement result to the network, so that the network can switch the UE to another neighboring cell. The offset Offset conn used for deprioritization is a negative value and can be a fixed value or a dynamic value.
作为实施方式,在将第一小区的信息添加到黑名单之后,UE还可以执行以下操作以防止UE重选第一小区。检测到UE处于空闲模式时,选择与第一小区不同的另一小区。As an implementation manner, after adding the information of the first cell to the blacklist, the UE may further perform the following operations to prevent the UE from reselecting the first cell: When it is detected that the UE is in an idle mode, another cell different from the first cell is selected.
在当前小区首次被添加到Listblacklist之后,当UE处于空闲模式时,UE将立即触发小区选择。除非没有其他可用的小区,否则Listblacklist中的任何小区都不会作为小区选择候选。After the current cell is first added to the List blacklist , the UE will immediately trigger cell selection when it is in idle mode. Unless there are no other available cells, any cell in the List blacklist will not be used as a cell selection candidate.
当UE返回第一小区所在的同一地点并且将要驻留到第一小区时,通过去优先级列表或黑名单,可以检测第一小区的信息是否在去优先级列表或黑名单中。在检测到第一小区的信息在黑名单中时,UE还可以执行类似的操作,即立即触发小区选择,并且Listblacklist中的任何小区都不会作为小区选择候选。When the UE returns to the same location where the first cell is located and is about to camp on the first cell, the UE can detect whether the information of the first cell is in the deprioritization list or the blacklist by deprioritization list or blacklist. When the UE detects that the information of the first cell is in the blacklist, the UE can also perform a similar operation, that is, triggering cell selection immediately, and any cell in the blacklist will not be used as a cell selection candidate.
作为实施方式,在将第一小区的信息添加到黑名单之后,UE还可以执行以下操作以防止UE重选第一小区。检测到UE处于RRC连接模式时,对第一小区的参数的实际测量结果应用用于黑名单的偏移,以获得处理后的测量结果,其中,用于黑名单的偏移大于用于去优先级的偏移,待测量的第一小区的参数由网络配置。将携带处理后的测量结果的测量报告发送到网络,其中,该测量报告用于网络基于处理后的测量结果将UE切换到另一小区。As an implementation manner, after adding the information of the first cell to the blacklist, the UE may also perform the following operations to prevent the UE from reselecting the first cell. When it is detected that the UE is in RRC connected mode, an offset for the blacklist is applied to an actual measurement result of a parameter of the first cell to obtain a processed measurement result, wherein the offset for the blacklist is greater than the offset for deprioritization, and the parameter of the first cell to be measured is configured by the network. A measurement report carrying the processed measurement result is sent to the network, wherein the measurement report is used by the network to switch the UE to another cell based on the processed measurement result.
在首次将当前小区添加到Listblacklist之后,当UE处于连接模式时,UE将更大的负数惩罚偏移值Offsetblack应用于服务小区测量结果(以及列表中的非服务小区),从而UE可以立即触发向网络的测量报告,并等待网络将UE切换到其他小区。当UE返回第一小区所在的同一地点并且将要驻留到第一小区时,通过去优先级列表或黑名单,可以检测第一小区的信息是否在去优先级列表或黑名单中。在检测到第一小区的信息在黑名单中时,还可以执行上述相同操作。After the current cell is added to the List blacklist for the first time, when the UE is in connected mode, the UE applies a larger negative penalty offset value Offset black to the serving cell measurement result (and the non-serving cells in the list), so that the UE can immediately trigger a measurement report to the network and wait for the network to switch the UE to other cells. When the UE returns to the same location where the first cell is located and is about to reside in the first cell, it can be detected whether the information of the first cell is in the deprioritization list or blacklist by deprioritization list or blacklist. When it is detected that the information of the first cell is in the blacklist, the same operation as above can also be performed.
作为实施方式,在向网络发送携带处理后的测量结果的测量报告之后,在发送测量报告时启动第二定时器。检测到在第二定时器到期之前UE切换到另一小区或UE返回空闲模式时,停止第二定时器。检测到在第二定时器到期之前UE未切换到另一小区或未返回空闲模式时,返回空闲模式以进行小区选择。As an implementation method, after sending a measurement report carrying the processed measurement result to the network, a second timer is started when sending the measurement report. When it is detected that the UE switches to another cell or the UE returns to idle mode before the second timer expires, the second timer is stopped. When it is detected that the UE does not switch to another cell or does not return to idle mode before the second timer expires, the idle mode is returned to perform cell selection.
具体地,在发出测量报告之后,UE可以启动定时器Thandover。如果在Thandover到期之前,网络将UE切换到另一小区或UE返回空闲模式,则停止Thandover。否则,当Thandover到期时,UE将在本地改变为空闲模式,然后选择另一小区(不在Listblacklist中)进行驻留。Specifically, after sending the measurement report, the UE may start the timer T handover . If the network switches the UE to another cell or the UE returns to the idle mode before T handover expires, T handover is stopped. Otherwise, when T handover expires, the UE will change to the idle mode locally and then select another cell (not in the List blacklist ) to camp on.
此外,如果某个RAT(2G/3G/4G/5G以及未来的RAT)具有较高百分比的小区导致问题,上述同样的动作可以扩展到问题RAT。下文还描述了一种使UE能够将问题RAT去优先级或加入黑名单一段时间的方案。Additionally, if a certain RAT (2G/3G/4G/5G and future RATs) has a higher percentage of cells causing problems, the same actions described above can be extended to the problematic RAT. A scheme is also described below that enables the UE to de-prioritize or blacklist the problematic RAT for a period of time.
对于不同的RAT(例如2G/3G/4G/5G),UE保持记录每个RAT的Listdepri中的小区的的Cab值之和。如果RAT的上述总和值大于Thab-deprat(用于RAT去优先级的阈值)但小于Thab-blrat(用于RAT黑名单的阈值),则考虑RAT去优先级(即,降低RAT优先级),否则,如果上述总和值大于Thab-blrat,则考虑将RAT加入黑名单(即,禁用RAT)。替代地,UE可以具有定义的定时器,以控制将RAT去优先级或加入黑名单的时长。这些动作仅在UE处于空闲模式下进行。For different RATs (e.g. 2G/3G/4G/5G), the UE keeps a record of the sum of the C ab values of the cells in the List depri of each RAT. If the above sum of the RAT is greater than Thab -deprat (threshold for RAT deprioritization) but less than Thab -blrat (threshold for RAT blacklisting), consider RAT deprioritization (i.e., lower RAT priority), otherwise, if the above sum is greater than Thab -blrat , consider adding the RAT to the blacklist (i.e., disabling the RAT). Alternatively, the UE may have a defined timer to control the duration of deprioritizing or blacklisting the RAT. These actions are performed only when the UE is in idle mode.
当UE决定将问题RAT去优先级一段时间(Tdeprirat),UE将RAT的信息加入RAT去优先级列表(Listdeprirat,如果该列表中未存在该信息)。Listdeprirat中的RAT相关信息将包含至少以下内容:RAT加入Listdeprirat的时间、Tdeprirat值、RAT的Cab值。即使在UE重启以后,列表Listdeprirat也将保持,从而记住该问题RAT。如果自添加RAT的信息起经过了时间Tdeprirat,则UE将从列表中移除该RAT。When the UE decides to deprioritize the problem RAT for a period of time (T deprirat ), the UE adds the information of the RAT to the RAT deprioritization list (List deprirat , if the information does not exist in the list). The RAT related information in List deprirat will contain at least the following: the time when the RAT was added to List deprirat , the T deprirat value, and the Cab value of the RAT. Even after the UE is restarted, the List deprirat will be maintained to remember the problem RAT. If the time T deprirat has passed since the RAT information was added, the UE will remove the RAT from the list.
当RAT首次被添加到Listdeprirat并且UE处于空闲模式时,UE将内部设置该RAT优先级为最低。由此,UE驻留在该RAT的任何小区上的可能性降低。When a RAT is first added to the List deprirat and the UE is in idle mode, the UE will internally set the priority of this RAT to the lowest, thereby reducing the possibility of the UE camping on any cell of this RAT.
当UE决定将问题RAT加入黑名单一段时间(Tblacklistrat),UE将RAT信息添加到Listblacklistrat(如果该列表中未存在该信息)。Listblacklistrat中的RAT相关信息将包含至少以下内容:RAT加入Listblacklistrat的时间、Tblacklistrat值、RAT的Cab值。When the UE decides to add the problematic RAT to the blacklist for a period of time (T blacklistrat ), the UE adds the RAT information to the List blacklistrat (if the information does not exist in the list). The RAT related information in the List blacklistrat will include at least the following: the time when the RAT was added to the List blacklistrat , the T blacklistrat value, and the C ab value of the RAT.
即使在UE重启后,该列表仍将保留,从而记住问题RAT。在经过时间Tblacklistrat后,UE将从列表中移除该RAT,并且UE将该RAT添加到支持列表。在当前RAT被添加到Listblacklistrat并且UE处于空闲模式时,UE将立即禁用该RAT并触发小区重选,UE将不会再驻留在该RAT的小区上。This list will remain even after a UE restart, thus remembering the problem RAT. After a time T blacklistrat has passed, the UE will remove the RAT from the list and the UE will add the RAT to the supported list. When the current RAT is added to the List blacklistrat and the UE is in idle mode, the UE will immediately disable the RAT and trigger a cell reselection, and the UE will no longer camp on a cell of that RAT.
作为实施方式,当UE移动到新地点或返回第一小区所在的同一地点时,UE可以检测第二小区的信息是否存在于列表中。当第二小区的信息存在于列表中时,根据列表选择小区。As an implementation, when the UE moves to a new location or returns to the same location where the first cell is located, the UE may detect whether the information of the second cell exists in the list. When the information of the second cell exists in the list, the cell is selected according to the list.
当UE返回第一小区所在的同一地点时,第二小区可以与第一小区相同。When the UE returns to the same location where the first cell is located, the second cell may be the same as the first cell.
列表可以包括去优先级列表和黑名单。通过基于第二小区的标识(identity,ID)查询去优先级列表或黑名单,可以检测去优先级列表或黑名单中是否存在第二小区的信息。第二小区的信息包括以下至少之一:PLMN相关信息、TAC、小区频率、PCI、GCI、将目标小区的信息添加到去优先级列表或黑名单的时间、第一定时器的时长Tdepri、以及至少一个异常事件发生的次数。第二小区指的是UE将要驻留的小区。The list may include a deprioritization list and a blacklist. By querying the deprioritization list or blacklist based on the identity (ID) of the second cell, it can be detected whether the information of the second cell exists in the deprioritization list or blacklist. The information of the second cell includes at least one of the following: PLMN related information, TAC, cell frequency, PCI, GCI, the time when the information of the target cell is added to the deprioritization list or blacklist, the duration T depri of the first timer, and the number of times at least one abnormal event occurs. The second cell refers to the cell where the UE will reside.
当去优先级列表中存在第二小区的信息时,在检测到UE处于空闲模式时,将第二小区的选择优先级设置为最低,并且对与目标小区对应的RSRP的实际测量结果应用偏移,以获得处理后的测量结果。可以基于处理后的测量结果和第二小区的选择优先级来选择小区。在检测到UE处于RRC连接模式时,对目标小区的参数的实际测量结果应用用于去优先级的偏移,以获得处理后的测量结果,并且向网络发送携带处理后的测量结果的测量报告,其中,该测量报告用于网络基于处理后的测量结果将UE切换到另一小区。因此,可以降低UE驻留到该UE曾驻留过的问题小区的可能性。When the information of the second cell exists in the deprioritization list, when it is detected that the UE is in idle mode, the selection priority of the second cell is set to the lowest, and an offset is applied to the actual measurement result of the RSRP corresponding to the target cell to obtain a processed measurement result. The cell can be selected based on the processed measurement result and the selection priority of the second cell. When it is detected that the UE is in RRC connection mode, an offset for deprioritization is applied to the actual measurement result of the parameter of the target cell to obtain a processed measurement result, and a measurement report carrying the processed measurement result is sent to the network, wherein the measurement report is used for the network to switch the UE to another cell based on the processed measurement result. Therefore, the possibility of the UE residing in a problem cell where the UE has resided can be reduced.
当黑名单中存在第二小区的信息时,在检测到UE处于RRC连接模式时,对目标小区的参数的实际测量结果应用用于黑名单的偏移,以获得处理后的测量结果。向网络发送携带处理后的测量结果的测量报告,其中,该测量报告用于网络基于处理后的测量结果将UE切换到另一小区。用于黑名单的偏移大于用于去优先级的偏移。因此,可以防止UE驻留到该UE曾驻留过的问题小区。When the information of the second cell exists in the blacklist, when it is detected that the UE is in RRC connected mode, the offset for the blacklist is applied to the actual measurement result of the parameter of the target cell to obtain a processed measurement result. A measurement report carrying the processed measurement result is sent to the network, wherein the measurement report is used by the network to switch the UE to another cell based on the processed measurement result. The offset for the blacklist is greater than the offset for deprioritization. Therefore, the UE can be prevented from residing in the problem cell where the UE has resided.
参考图3和图4,图3描述了将目标小区的信息添加到去优先级列表时的操作,图4描述了将目标小区的信息添加到黑名单时的操作。3 and 4 , FIG. 3 describes an operation when adding information of a target cell to a deprioritization list, and FIG. 4 describes an operation when adding information of a target cell to a blacklist.
图3是根据实施方式的避开问题小区的方法的流程示意图。如图3所示,避开问题小区的方法包括以下内容。Fig. 3 is a schematic flow chart of a method for avoiding problem cells according to an embodiment. As shown in Fig. 3, the method for avoiding problem cells includes the following contents.
在框202,检测到目标小区的信号强度大于第三阈值。At block 202, it is detected that the signal strength of the target cell is greater than a third threshold.
在框204,检测到UE驻留的目标小区发生至少一个异常事件。At block 204, at least one abnormal event is detected to occur in the target cell where the UE is camped.
在框206,确定至少一个异常事件发生的次数大于第一阈值且小于第二阈值。At block 206 , it is determined that the number of times at least one abnormal event occurs is greater than a first threshold and less than a second threshold.
在框208,检测UE的模式,其中,UE的模式包括空闲模式和RRC连接模式。At block 208, a mode of the UE is detected, wherein the mode of the UE includes an idle mode and an RRC connected mode.
当UE处于不同模式时,可以执行将目标小区去优先级的不同操作。具体地,在检测到UE处于空闲模式时,执行框210的操作;在检测到UE处于RRC连接模式时,执行框212的操作。When the UE is in different modes, different operations for deprioritizing the target cell may be performed. Specifically, when the UE is detected to be in idle mode, the operation of block 210 is performed; when the UE is detected to be in RRC connected mode, the operation of block 212 is performed.
在框210,在检测到UE处于空闲模式时,将目标小区的选择优先级设置为最低,并且对与目标小区对应的RSRP的实际测量结果应用偏移,以获得处理后的测量结果,基于处理后的测量结果选择小区。In block 210, when it is detected that the UE is in idle mode, the selection priority of the target cell is set to the lowest, and an offset is applied to the actual measurement result of RSRP corresponding to the target cell to obtain a processed measurement result, and a cell is selected based on the processed measurement result.
在框212,在检测到UE处于RRC连接模式时,对目标小区的参数的实际测量结果应用用于去优先级的偏移,以获得处理后的测量结果,向网络发送携带处理后的测量结果的测量报告。At block 212, when it is detected that the UE is in the RRC connected mode, an offset for de-prioritization is applied to the actual measurement result of the parameter of the target cell to obtain a processed measurement result, and a measurement report carrying the processed measurement result is sent to the network.
目标小区的待测量参数由网络配置。测量报告用于网络基于处理后的测量结果将UE切换到另一小区。The parameters to be measured of the target cell are configured by the network. The measurement report is used by the network to switch the UE to another cell based on the processed measurement results.
在执行将目标小区去优先级的操作(例如框210和212的操作)时,还可以将目标小区的信息添加到去优先级列表。这样在UE返回目标小区所在的同一地点时,在驻留到UE可以从其接收信号的目标小区之前,UE可以检测目标小区的信息是否存在于去优先级列表或黑名单中。当目标小区的信息存在于去优先级列表或黑名单中时,UE可以选择另一小区而不驻留到有问题的目标小区。因此,当UE回到问题小区时,可以降低驻留到问题小区的可能性,甚至可以避开那些问题小区。When performing the operation of deprioritizing the target cell (e.g., the operation of blocks 210 and 212), the information of the target cell may also be added to the deprioritization list. In this way, when the UE returns to the same location where the target cell is located, before camping on the target cell from which the UE can receive signals, the UE can detect whether the information of the target cell exists in the deprioritization list or the blacklist. When the information of the target cell exists in the deprioritization list or the blacklist, the UE can select another cell instead of camping on the problematic target cell. Therefore, when the UE returns to the problem cell, the possibility of camping on the problem cell can be reduced, and even those problem cells can be avoided.
在框214,确定去优先级列表中是否存在目标小区的信息。At block 214, it is determined whether information of the target cell exists in the deprioritized list.
在框216,当确定去优先级列表中不存在目标小区的信息时,将目标小区的信息添加到去优先级列表。In block 216, when it is determined that the information of the target cell does not exist in the deprioritization list, the information of the target cell is added to the deprioritization list.
目标小区的信息包括以下至少之一:PLMN相关信息、TAC、小区频率、PCI、GCI、将目标小区的信息添加到去优先级列表的时间、第一定时器的时长、以及至少一个异常事件发生的次数。The target cell information includes at least one of the following: PLMN related information, TAC, cell frequency, PCI, GCI, time when the target cell information is added to the deprioritization list, duration of the first timer, and number of occurrences of at least one abnormal event.
在框218,在检测到去优先级列表中存在目标小区的信息时,将目标小区的信息从去优先级列表中移除,并且将目标小区加入黑名单。In block 218, when it is detected that the information of the target cell exists in the deprioritization list, the information of the target cell is removed from the deprioritization list, and the target cell is added to the blacklist.
在框220,当确定去优先级列表中存在目标小区的信息时,在检测到第一定时器到期时,将目标小区的信息从去优先级列表中移除,其中,第一定时器的时长基于至少一个异常事件发生的次数。In block 220 , when it is determined that the target cell information exists in the deprioritization list, the target cell information is removed from the deprioritization list upon detecting expiration of a first timer, wherein the duration of the first timer is based on the number of occurrences of at least one abnormal event.
框202-220的操作的细节可以参考图1和图2的对应描述,在此不再赘述。The details of the operations of blocks 202 - 220 may refer to the corresponding descriptions of FIG. 1 and FIG. 2 , and will not be repeated here.
图4是根据实施方式的避开问题小区的方法流程示意图。如图4所示,避开问题小区的方法包括以下内容。Fig. 4 is a schematic flow chart of a method for avoiding problem cells according to an embodiment. As shown in Fig. 4, the method for avoiding problem cells includes the following contents.
在框302,检测到目标小区的信号强度大于第三阈值。At block 302, it is detected that the signal strength of the target cell is greater than a third threshold.
在框304,检测到UE驻留的目标小区发生至少一个异常事件。At block 304, at least one abnormal event is detected to occur in the target cell where the UE is camped.
在框306,确定至少一个异常事件发生的次数大于第二阈值。At block 306 , it is determined that the number of occurrences of the at least one abnormal event is greater than a second threshold.
在框308,检测UE的模式。At block 308, a mode of the UE is detected.
当UE处于不同模式时,可以执行将目标小区加入黑名单的不同操作。具体地,在检测到UE处于空闲模式时,执行框310的操作;在检测到UE处于RRC连接模式时,执行框312和框318的操作。When the UE is in different modes, different operations of adding the target cell to the blacklist may be performed. Specifically, when the UE is detected to be in idle mode, the operation of box 310 is performed; when the UE is detected to be in RRC connected mode, the operations of boxes 312 and 318 are performed.
在框310,在检测到UE处于空闲模式时,通过将目标小区加入黑名单来选择另一小区,即选择与目标小区不同的另一小区。At block 310, upon detecting that the UE is in idle mode, another cell is selected by blacklisting the target cell, ie, another cell different from the target cell is selected.
在框312,在检测到UE处于RRC连接模式时,对目标小区的参数的实际测量结果应用用于黑名单的偏移,以获得处理后的测量结果,将携带处理后的测量结果的测量报告发送到网络。At block 312, upon detecting that the UE is in RRC connected mode, an offset for the blacklist is applied to the actual measurement result of the parameter of the target cell to obtain a processed measurement result, and a measurement report carrying the processed measurement result is sent to the network.
在框314,在发送测量报告时,启动第二定时器。At block 314, when the measurement report is sent, a second timer is started.
在框316,检测到在第二定时器到期之前UE切换到另一小区或UE返回空闲模式时,停止第二定时器。At block 316, upon detecting that the UE switches to another cell or the UE returns to idle mode before the second timer expires, the second timer is stopped.
在框318,检测到在第二定时器到期之前UE未切换到另一小区或返回空闲模式时,返回空闲模式以进行小区选择。At block 318, upon detecting that the UE does not switch to another cell or return to idle mode before the second timer expires, the UE returns to idle mode for cell selection.
用于黑名单的偏移大于用于去优先级的偏移。目标小区的待测量参数由网络配置。测量报告用于网络基于处理后的测量结果将UE切换到另一小区。The offset used for blacklisting is larger than the offset used for deprioritization. The parameters to be measured for the target cell are configured by the network. The measurement report is used by the network to hand over the UE to another cell based on the processed measurement results.
在执行将目标小区加入黑名单的操作(例如框310至框318的操作)时,还可以将目标小区的信息添加到黑名单。这样在UE返回目标小区所在的同一地点时,在驻留到UE可以从其接收信号的目标小区之前,UE可以检测目标小区的信息是否存在于去优先级列表或黑名单中。当目标小区的信息存在于去优先级列表或黑名单中时,UE可以选择另一小区而不驻留到有问题的目标小区。因此,当UE回到问题小区时,可以降低驻留到问题小区的可能性,甚至可以避开那些问题小区。When performing the operation of adding the target cell to the blacklist (e.g., the operation of box 310 to box 318), the information of the target cell can also be added to the blacklist. In this way, when the UE returns to the same location where the target cell is located, before camping on the target cell from which the UE can receive signals, the UE can detect whether the information of the target cell exists in the deprioritization list or the blacklist. When the information of the target cell exists in the deprioritization list or the blacklist, the UE can select another cell instead of camping on the problematic target cell. Therefore, when the UE returns to the problem cell, the possibility of camping on the problem cell can be reduced, and even those problem cells can be avoided.
在框320,将目标小区的信息添加到黑名单。At block 320, the target cell's information is added to the blacklist.
目标小区的信息包括以下至少之一:PLMN相关信息、TAC、小区频率、PCI、GCI、将目标小区添加到黑名单的时间、第一定时器的时长、以及至少一个异常事件发生的次数。The target cell information includes at least one of the following: PLMN related information, TAC, cell frequency, PCI, GCI, time when the target cell is added to the blacklist, duration of the first timer, and number of occurrences of at least one abnormal event.
在框322,在检测到第一定时器到期时,从黑名单中移除小区的信息。At block 322, upon detecting expiration of the first timer, the information of the cell is removed from the blacklist.
第一定时器的时长基于至少一个异常事件发生的次数。此外,第一定时器的时长可以如下动态更新。在监控周期内确定目标小区被加入黑名单的次数。根据目标小区被加入黑名单的次数,更新第一定时器的时长。The duration of the first timer is based on the number of times at least one abnormal event occurs. In addition, the duration of the first timer can be dynamically updated as follows: Determine the number of times the target cell is added to the blacklist during the monitoring period. Update the duration of the first timer according to the number of times the target cell is added to the blacklist.
框302-322的操作的细节可以参考图1和图2的对应描述,在此不再赘述。The details of the operations of blocks 302 - 322 may refer to the corresponding descriptions of FIG. 1 and FIG. 2 , and will not be repeated here.
参考图5,图5是根据其他实施例的避开问题小区的方法的示意图。如图5所示且如上文实施方式所示,UE检测到小区(图5中的阴影区域表示)的问题,将小区添加到去优先级列表,然后重选或切换到(由图5的箭头表示)另一小区。替代地,UE检测到小区(图5中的阴影区域表示)的问题,将小区加入黑名单,然后重选或切换到(由图5的箭头表示)另一小区。Referring to FIG5 , FIG5 is a schematic diagram of a method for avoiding problem cells according to other embodiments. As shown in FIG5 and as shown in the above embodiments, the UE detects a problem with a cell (represented by the shaded area in FIG5 ), adds the cell to a deprioritized list, and then reselects or switches to (represented by the arrows in FIG5 ) another cell.
