Description

一种实现5G信号平稳显示的方法
本申请要求于2020年4月21日提交中国专利局、申请号为202010315915.7、发明名称为“一种实现5G信号平稳显示的方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，具体涉及一种实现5G信号平稳显示的方法。
 背景技术
5G是新一代移动通信技术，存在两种组网方案，NSA（非独立组网）和SA（独立组网），二者之间有着明显的区别。NSA（非独立组网）组网是基于现有的4G基础设施上部署的，部分的业务和功能继续依赖4G网络，其优势是可以节省建设成本，实现快速覆盖。NSA通过改造4G基站来传输5G信号，前期铺设速度快、成本低，可以尽快使得5G普及开来，让尽可能多的用户享受到。而SA需要建造独立基站，实现大规模的覆盖需要的时间成本较高，但是SA具备更高的速率和更低的延时等特性。未来在向SA发展的过程中，NSA必定会有一个长时间的过渡期，因此NSA的组网在5G网络建设初期是大部分运营商考虑的首选，即在全面覆盖SA组网之前，NSA组网的网络会长期存在于现网当中，与SA的网络共存。这也意味着，NSA/SA双模将会是行业主流趋势。因此，在未来的双模5G时代，双模5G手机才可以提供更完善的5G网络体验。
目前部署的大多数5G网络是NSA制式的eMBB网络，依托于成熟的LTE网络覆盖，同时又能发挥双连接ENDC中gNB（5G基站）的高吞吐量。为了区别于LTE网络，于是需要在终端连接上ENDC（5G ENDC系统架构如图1所示）网络时，在UI（用户设备）界面显示当前网络为5G。在4G网络，RRC（无线资源控制）释放，也依旧显示4G，但是ENDC网络中gNB与终端之间不存在RRC控制链路，因此LTE的RRC连接释放，会导致SCG释放。在终端移动过程中，网络环境不断变化，如果此时用户正在使用5G手机，但是LTE的RRC变为Idle（空闲态）了，可能UI会显示为4G，用户会发现5G信号不稳定，会在4G和5G之间频繁变化，导致用户认为终端5G信号不佳，可能用户投诉终端厂商或者运营商，对产品质量和品牌口碑造成一定的影响。

 本发明的实施方式
在ENDC初始接入过程中，MN (MN：Master Node，ENDC网络中eNB充当MN角色)检查当前终端如果允许接入双连接网络，则通过MN下发测量配置和测量上报的event，当终端测量到LTE的5G邻区满足B1 event后上报测量配置给MN，MN通知SN(SN：Secondary Node，ENDC网络中gNB充当SN角色)。当前UE满足接入条件,于是SN通过X2接口将SN的RRC重配置和承载配置消息发送给MN，MN打包一起发送给终端（ENDC网络中终端与gNB不存在RRC连接，NR空口控制消息依旧通过LTE小区进行传递）。终端根据下发的SN网络配置，然后在信道上接收SN的MIB（Master Information Block，主系统信息块）消息并尝试发起RACH随机接入过程，如果返回RACH的Result是Success的，则表明终端已成功接入5G NR的SN网路（5G辅小区）。
其中，规范TS38.331 5.7.3.3定义了多种SCG Failure的类型，此时MCG（主小区组）会下发RRC重配释放SCG（辅小区组），当RRC重建成功会重新根据邻区情况决定是否添加SCG。终端在双连接网络下，会根据5G信号显示算法决定是否显示5G，终端显示5G的前提下，遇到网络异常或者无数据传输均会释放SCG。NSA网络小区切换导致SCG释放，然后重新建立SCG的情况包含以下几种：MN切换，伴随SN改变；MN切换，伴随SN不变；MN切换，伴随SN变更；MN切换，伴随SN添加（原来是LTE单连接，或者从其它RAT切换到MN）；MN切换，伴随SN释放。其中，主节点用MN表示，辅节点用SN表示。
其中，终端无数据业务进行时，网络定时器超时后会主动释放MCG的RRC连接，因此会释放SCG。当终端出现释放SCG承载时，目前一般通过单一的定时器来判断，即当网络释放SCG承载以后，启动定时器,如果定时器超时以后，双连接还没有建立（即SCG没有完成添加），即显示为4G，定时器时间设置过长，可能不能真实反映网络注册情况，定时器设置过短，就会导致信号频繁变化，比如出现5G->4G->5G的信号跳变过程。因此，本发明实施例设置三个定时器，依次对5G信号进行判断。
本申请实施例提供一种实现5G信号平稳显示的方法，包括：双连接网络切换主节点，释放辅小区组承载，开启第一定时器，显示5G信号；判断所述第一定时器超时，检测无线资源控制处于空闲态，开启第二定时器，显示5G信号；判断所述第二定时器超时，检测无线资源控制处于连接态，查询数据无线承载的数量，根据所述数量显示信号类型；检测无线资源控制处于空闲态，查询5G小区信息数据库，根据5G小区信息显示信号类型。
如图2所示，该实现5G信号平稳显示的方法的具体流程可以如下：
101、双连接网络切换主节点，释放辅小区组承载，开启第一定时器，显示5G信号。
例如，在双连接网络下，用户终端移动的过程中，NSA小区切换会导致SCG承载释放。此时开启第一定时器T1，终端界面继续显示5G信号。
其中，如果第一定时器T1没有超时，双连接重新建立，则终端界面继续显示5G信号。
102、判断所述第一定时器超时，检测无线资源控制处于空闲态，开启第二定时器，显示5G信号。
例如，判断第一定时器T1超时后，检测RRC的状态，如果RRC处于空闲态，即双连接还没有建立，此时开启第二定时器T2，终端界面继续显示5G信号。
其中，判断第一定时器T1超时后，检测RRC的状态，如果RRC处于连接态，此时查询数据无线承载（DRB）的数量，根据DRB的数量显示信号的类型。如果查询到DRB的数量为1，即此时只存在一个DRB承载，则终端界面显示4G信号，如果查询到DRB的数量为2，即此时存在两个DRB承载，SCG添加完成，则终端界面显示5G信号。
其中，数据无线承载包括主小区组承载和辅小区组承载，主小区组为4G小区，辅小区组承载为5G小区，终端根据当前是否存在两个DRB承载，可以知道当前是否存在SCG网络连接。
其中，Modem中存在数据库1（drb_db）本地存储DRB的列表，并根据SCG和MCG的网络变化及时更新数据库1：RRC重配消息中drb-ToAddModList字段包含的drb-identity与LTE的DRB承载索引不同时，将其添加到数据库1中；RRC重配消息中drb-ToRelelaseList包含的drb-identity与NR的DRB承载索引相同时时，将其从数据库1中删除。数据库1除了存储DRB列表以外，还存储一个DRB数量的字段num，用于记录当前数据库中总的DRB数。
103、判断第二定时器超时，检测无线资源控制处于连接态，查询数据无线承载的数量，根据所述数量显示信号类型。
例如，判断第二定时器T2超时后，检测无线资源控制的状态，如果无线资源控制处于连接态，此时查询DRB的数量，根据DRB的数量显示信号的类型。如果查询到DRB的数量为1，即此时只存在一个DRB承载，则终端界面显示4G信号，如果查询到DRB的数量为2，即此时存在两个DRB承载，SCG添加完成，则终端界面显示5G信号。
其中，如果第二定时器T2没有超时，双连接重新建立，则终端界面继续显示5G信号。
104、检测无线资源控制处于空闲态，查询5G小区信息数据库，根据5G小区信息显示信号类型。
例如，判断第二定时器T2超时后，检测无线资源控制的状态，如果无线资源控制处于空闲态，则查询5G小区信息数据库，根据5G小区信息显示信号类型。
其中，在RRC处于空闲态时，触发小区重选到的目标小区，即重选的MCG小区支持双连接网络，则查询5G小区信息数据库，如果5G小区信息数据库中包含一组5G小区的MIB消息，则开启第三定时器T3，终端界面显示5G信号。
其中，判断第三定时器T3是否超时，如果判断第三定时器T3超时后，则查询此时DRB的数量，根据DRB的数量显示数据类型。如果查询到的DRB的数量为0，即此时RRC为空闲态，则终端界面显示4G信号；如果查询到DRB的数量为1，即此时RRC为连接态，只存在一个DRB承载，则终端界面显示4G信号；如果查询到DRB的数量为2，即此时RRC为连接态，存在两个DRB承载，SCG添加完成，则终端界面显示5G信号。
其中，在RRC处于空闲态时，触发小区重选到的目标小区，即重选的MCG小区不支持双连接网络时，则5G小区信息数据库为空，终端界面显示4G信号。
其中，用户设备在每接入一个MCG小区，网络都会通过RRC重配消息下发测量控制，如果MCG的小区支持双连接网络，则会继续下发RRC重配消息添加SCG，随机接入前要先获取5G小区的MIB消息，包含的PCI（物理小区标识）和Frequency（频率）先缓存起来，如果RACH（随机接入信道）成功以后，则将这两个内容的值存储到5G小区信息数据库（nrinfo_db）中，该数据库只能存储一组数据。如果MCG小区未发生变化，即使RRC释放了，5G小区信息数据库不更新。小区重选后，若系统消息中upperLayerIndication的字段为true即支持双连接网络，获取到5G小区的MIB消息中的Frequency和PCI都不一致时，则更新5G小区信息数据库为获取的内容值；若新的测控信息中无5G小区信息时，则清空5G小区信息数据库。小区重选后，若系统消息中upperLayerIndication的字段为false即不支持双连接网络，则清空5G小区信息数据库。
其中，如果第三定时器T3没有超时，双连接重新建立，则终端界面继续显示5G信号。
其中，对于每一定时器的时间设置，可以自定义调整，三个定时器的时间之和一般不超过25秒。
如图3所示，本申请实施例提供了一种实现5G信号平稳显示的方法的工作流程图。
请参阅图3，双连接网络下，终端在移动过程中，出现RRC直接释放或者SCG释放后，启动第一定时器T1，终端设备继续显示5G信号，接着判断T1是否超时，若T1没有超时，双连接重新建立，则终端显示5G信号。若T1超时，则检测RRC的状态。如果RRC处于连接态，查询此时DRB的数量，根据DRB的数量显示信号的类型，如果查询到DRB的数量为1，即此时只存在一个DRB承载，则终端界面显示4G信号，如果查询到DRB的数量为2，即此时存在两个DRB承载，SCG添加完成，则终端界面显示5G信号。如果RRC处于空闲态，即双连接还没有建立，此时开启第二定时器T2，终端界面继续显示5G信号。
然后判断第二定时器T2是否超时，如果第二定时器T2没有超时，双连接重新建立，则终端界面继续显示5G信号。如果判断第二定时器T2超时后，检测RRC的状态，如果RRC处于连接态，此时查询DRB的数量，根据DRB的数量显示信号的类型，如果查询到DRB的数量为1，即此时只存在一个DRB承载，则终端界面显示4G信号，如果查询到DRB的数量为2，即此时存在两个DRB承载，SCG添加完成，则终端界面显示5G信号。如果RRC处于空闲态，则查询5G小区信息数据库，根据5G小区信息显示信号类型，如果5G小区信息数据库为空，则终端界面显示4G信号；如果5G小区信息数据库中包含一组5G小区的MIB消息，则开启第三定时器T3，终端界面显示5G信号。
最后判断第三定时器T3是否超时，如果判断第三定时器T3超时后，则查询此时DRB的数量，根据DRB的数量显示数据类型，如果查询到DRB的数量为2，即此时RRC为连接态，存在两个DRB承载，SCG添加完成，则终端界面显示5G信号，如果查询到的DRB的数量不为2，则无论此时RRC为何状态，终端界面显示4G信号。
如图4所示，本申请实施例提供了一种5G信号分类上报的流程示意图；终端执行上述实现5G信号平稳显示的方法后，获取到当前5G的状态，再根据注册的频段是FR1/FR2/仅4G三种情况，分类上报信号图标，注册FR1频段，上报显示5G Basic（基带），注册FR2，上报显示5G UWB（超宽带），如果未注册5G，则上报Null。RILD根据这个上报的mask，决定是否显示5G，并通过AP侧的接口，传递到UI系统进行信号图标更新。
为了更好地实施以上方法，本申请实施例还可以提供一种实现5G信号平稳显示的装置，该实现5G信号平稳显示的装置应用于终端设备。

（2）检测单元502

例如，判断单元501在判断第一定时器T1超时后，检测单元502检测RRC的状态，检测RRC此时处于连接态还是空闲态；判断单元501在判断第二定时器超时后，检测单元502检测此时RRC的状态，检测RRC是处于连接态还是空闲态。
（3）查询单元503
查询单元503，用于查询数据无线承载的数量以及查询5G小区信息数据库。
例如，查询单元503包括两个查询子单元，查询子单元1用于在判断第二定时器超时且RRC处于连接态时，查询DRB的数量，根据DRB的数量显示信号的类型；查询子单元2用于在判断第二定时器超时且RRC处于空闲态时，查询5G小区信息数据库，根据5G小区信息显示信号类型。
（4）显示单元504
显示单元504，用于显示信号的类型。
例如，双连接网络下，用户设备在切换MCG小区，释放SCG承载时，第一定时器开启，此时终端设备的显示单元继续显示5G信号；如果第一定时器没有超时，则显示单元继续显示5G信号；判断第一定时器超时且RRC处于空闲态时，开启第二定时器，显示单元显示5G信号；判断第一定时器超时且RRC处于连接态时，如果查询到DRB的数量为1，则显示单元显示4G信号，如果查询到DRB的数量为2，则显示单元显示5G信号。如果第二定时器没有超时，则显示单元继续显示5G信号；判断第二定时器超时且RRC处于连接态时，如果查询到DRB的数量为1，则显示单元显示4G信号，如果查询到DRB的数量为2，则显示单元显示5G信号；判断第二定时器超时且RRC处于空闲态时，如果5G小区信息数据库中包含一组5G小区的MIB消息，则开启第三定时器，显示单元显示5G信号，如果5G小区信息数据库为空，则显示单元显示4G信号。如果第三定时器没有超时，则显示单元继续显示5G信号；判断第三定时器超时，如果查询到DRB的数量为2，则显示单元显示5G信号，如果查询到DRB的数量不为2，则显示单元显示4G信号。
