其中,所述目标主小区包括主小区组的主小区和辅小区组的主小区。
在系统支持至少两次条件切换尝试的情况下,启动第一定时器或启动第一定时器和计数器,并根据所启动的统计器件的统计值与预设阈值的关系,来确定条件切换结果,进而使得终端能够根据该条件切换结果,准确地获知条件切换是否失败,并在确定最终条件切换失败后,发起RRC连接重建过程等。
进一步地,确定所述条件切换结果为最终条件切换失败之后,执行以下至少一项行为:
回退到应用原主小区组的主小区或辅小区的配置的状态,或者应用原辅小区组的主小区或辅小区的配置的状态,或者应用原服务小区的配置的状态;
记录失败信息;
上报失败信息;
发起RRC连接重建过程;
在源无线接入技术RAT与所切换的目标RAT不同时,发起源RAT所定义的相关过程;
删除所有的条件切换配置信息。
其中,上报失败信息的具体过程与上述系统支持一次条件切换尝试中的上报过程相同,此处不再赘述。
下面结合图2对系统支持至少两次条件切换尝试的实现流程进行说明。
如图2所示,该实现流程包括:
步骤S11:源节点给一个或多个目标节点发送切换请求信息。
步骤S12:目标节点给源节点反馈切换确认消息。
步骤S13:源节点给UE发送条件切换的配置信息。
步骤S14:UE收到条件切换的配置信息后,持续评估候选小区是否满足 条件,在满足条件后,UE会选择一个相应的配置信息,开始进行后续的过程。
需要说明的是,在步骤3和步骤4进行的过程中,终端会启动一个或多个用于检测最终条件切换结果的定时器timer(如,t30x)以及零个或至少一个用于检测最终条件切换结果的计数器counter(如,N3xx),timer和counter的启动时刻可能为以下几种情况之一:
a.接收到至少一个候选小区的条件切换的配置信息的时刻;
b.应用至少一个候选小区的条件切换的配置信息的时刻;
c.在评估出至少一个候选小区满足条件切换后,触发条件切换的时刻。
对于上述timer,启动单个的情况下可能为以下几种配置之一,启动多个timer的情况下可以包括但不限于以下配置的任意组合,且对于每种类型的timer,也可以启动多个:
1.定时器配置为用于一个UE,该定时器可用于最终条件切换失败(Handover failure,HOF)的检测,单次条件切换失败不停止计时;也可以用于单次条件切换失败的检测,在定时器超时且单次条件切换失败发生后,发起新的条件切换,并重置定时器。
2.定时器配置为用于一个命令,即每个条件切换的配置信息均有一个独立的定时器,不同条件切换的配置信息的定时器的计时时长可以相同也可以不同。
3.定时器配置为用于多个条件切换的配置信息,即若干个条件切换的配置信息共用一个定时器,例如,该定时器可用于单次条件切换失败的检测,在定时器超时且单次条件切换失败发生后,发起新的条件切换,并重置定时器。
对于上述counter配置为用于一个UE,即每个UE应用一个counter。此counter可用于最终HOF的检测,在单次条件切换失败时,counter的计数值+1。
另外,在用于HO failure的timer(如,t30x)运行时,执行以下至少一项行为:
在检测到目标主小区后,启动无线链路监测RLM的测量,并采用RLM计数器,禁止启动RLM的定时器;
在收到随机接入过程失败指示时,不触发无限链路恢复过程(如,RRC连接重建);
在收到RLC达到最大重传次数的指示时,触发无线链路失败;
其中,所述目标主小区包括主小区组的主小区和辅小区组的主小区。
上述RLM计数器包括同步计数器(如,N310)和非同步计数器(如N311),上述RLM的定时器可以为t310。
上述后续的过程包括以下至少一项:
应用第一条件切换配置信息,所述第一条件切换配置信息为满足切换条件的条件切换配置信息;
删除至少一个第二条件切换配置信息,所述第二条件切换配置信息为条件切换配置信息中除第一条件切换配置信息之外的条件切换配置信息;
停止对至少一个第二条件切换配置信息中切换条件是否满足的评估;
在选择的目标小区发起接入过程。
步骤S15:UE向选择的目标小区发起接入过程。
此时,UE会获取定时器的计时时长,对于单次条件切换过程,如果在定时器超时之前(计时时长未达到第一预设阈值),条件切换成功,则控制定时器停止计时;如果定时器超时(计时时长达到第一预设阈值),则确定条件切换失败。
其中,在UE判断出满足以下至少一项时,确定条件切换成功:
成功接入目标小区;
成功收到小区无线网络临时标识C-RNTI加扰的物理下行控制信道PDCCH传输;
成功应用基站下发的目标小区的配置(如,目标小区的UE专属信令);
成功应用基站广播的系统信息(如,目标小区的系统消息SIB1和SIB2中的至少一项);
成功发送基站请求发送的终端辅助信息(如,向目标小区发送的UE辅助信息)。
进一步地,若发生单次条件切换失败,则UE在满足触发条件的目标小区配置中选择一个配置(如,另外一个目标小区配置)再次发起条件切换过 程,用于单次切换的定时器进行重置(如果配置一个timer用于每次新的单次条件切换过程)或者重新启动一个定时器(如果独立配置一个timer用于该次新的条件切换过程)。
对于用于检测最终HOF的检测的定时器或计数器:
1.如果启动且只启动了用于最终HOF检测的timer,在其超时之前,成功完成了条件切换过程,该timer停止计时,在其超时之前,未成功完成条件切换,则在定时器超时后触发HOF,最终切换失败。
2.如果启动且只启动了用于最终HOF检测的counter,在其达到最大值之前,成功完成了条件切换过程,该counter停止计数.在其达到最大值之前,未成功完成条件切换,则在counter达到最大值之后触发HOF,最终切换失败。
3.如果同时启动了用于最终HOF的检测的timer和counter,在timer超时和counter达到最大值之前,成功完成了条件切换过程,则timer和counter停止。若一直未成功完成条件切换过程,则在timer超时或counter达到最大值之后触发HOF,最终切换失败。
上述所述timer或counter的最大值可以为预先配置,即时配置或协议规定。
需要说明的是,对于多次条件切换的过程,可以有两个timer,例如t30x和t30y,其中该t30x用于判断1次条件切换尝试失败,t30y用于判断整个多次条件切换的失败;或者有1个timer(t30x)和1个counter(n30x),其中,t30x用于判断1次条件切换尝试失败,n30x用于判断整个多次条件切换的失败。
若最终切换失败,UE的行为为以下一项或多项任意组合:
回退到应用原主小区组的主小区或辅小区的配置的状态,或者应用原辅小区组的主小区或辅小区的配置的状态,或者应用原服务小区的配置的状态;
记录失败信息;
上报失败信息;
发起RRC连接重建过程;
在源无线接入技术RAT与所切换的目标RAT不同时,发起源RAT所定 义的相关过程;
删除所有的条件切换配置信息。
本公开实施例中,对于多次条件切换的过程,可以用两个定时器或者用一个定时器和一个计数器,来确定条件切换结果,例如,可以用t30x和t30y来确定条件切换结果,其中,t30x用于判断1次条件切换尝试的失败,t30y用于判断整个多次条件切换的失败,又例如,可以用t30x和计数器n30x来确定条件结果,其中,t30x用于判断1次条件切换尝试的失败,n30x用于判断整个多次条件切换的失败。

接口单元508为外部装置与终端500连接的接口。例如,外部装置可以包括有线或无线头戴式耳机端口、外部电源(或电池充电器)端口、有线或无线数据端口、存储卡端口、用于连接具有识别模块的装置的端口、音频输入/输出(I/O)端口、视频I/O端口、耳机端口等等。接口单元508可以用于接收来自外部装置的输入(例如,数据信息、电力等等)并且将接收到的输入传输到终端500内的一个或多个元件或者可以用于在终端500和外部装置之间传输数据。
存储器509可用于存储软件程序以及各种数据。存储器509可主要包括存储程序区和存储数据区,其中,存储程序区可存储操作系统、至少一个功能所需的应用程序(比如声音播放功能、图像播放功能等)等;存储数据区可存储根据手机的使用所创建的数据(比如音频数据、电话本等)等。此外,存储器509可以包括高速随机存取存储器,还可以包括非易失性存储器,例如至少一个磁盘存储器件、闪存器件、或其他易失性固态存储器件。
处理器510是终端的控制中心,利用各种接口和线路连接整个终端的各个部分,通过运行或执行存储在存储器509内的软件程序和/或模块,以及调用存储在存储器509内的数据,执行终端的各种功能和处理数据,从而对终端进行整体监控。处理器510可包括一个或多个处理单元;可选的,处理器510可集成应用处理器和调制解调处理器,其中,应用处理器主要处理操作系统、用户界面和应用程序等,调制解调处理器主要处理无线通信。可以理解的是,上述调制解调处理器也可以不集成到处理器510中。
终端500还可以包括给各个部件供电的电源511(比如电池),可选的, 电源511可以通过电源管理系统与处理器510逻辑相连,从而通过电源管理系统实现管理充电、放电、以及功耗管理等功能。
另外,终端500包括一些未示出的功能模块,在此不再赘述。
需要说明的是,在本文中,术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含,从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素,而且还包括没有明确列出的其他要素,或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下,由语句“包括一个……”限定的要素,并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
通过以上的实施方式的描述,本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现,当然也可以通过硬件,但很多情况下前者是更佳的实施方式。基于这样的理解,本公开的技术方案本质上或者说对相关技术做出贡献的部分可以以软件产品的形式体现出来,该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中,包括若干指令用以使得一台终端(可以是手机,计算机,服务器,空调器,或者网络设备等)执行本公开各个实施例所述的方法。
上面结合附图对本公开的实施例进行了描述,但是本公开并不局限于上述的具体实施方式,上述的具体实施方式仅仅是示意性的,而不是限制性的,本领域的普通技术人员在本公开的启示下,在不脱离本公开宗旨和权利要求所保护的范围情况下,还可做出很多形式,均属于本公开的保护之内。
