Description

非授权载波的测量上报方法和终端及配置方法和基站 技术领域
本申请涉及但不限于通信领域，尤其涉及一种非授权载波的测量上报方法和终端及配置方法和基站。
背景技术
在移动通信系统中，小区重选和切换是其重要的功能。为了顺利实现小区重选，UE(User Equipment，终端)需要对不同小区的信号质量进行测量，以便选择合适的小区进行驻留。当UE在某个小区与网络建立连接之后，UE仍然需要对其相邻小区的信号质量进行测量，以便选择合适的小区进行切换，满足移动性要求。
长期演进(LTE，Long Term Evolution)系统中，在连接态下，测量的具体过程是：网络侧将测量控制消息发送给UE，其中，该测量控制消息中包括测量标识、测量对象、报告配置以及测量的其他相关属性。测量对象包含了测量对象属性(如载频、邻区列表等)，报告配置包含了报告配置属性(如事件触发或周期上报、触发的事件定义(A1、A2…)、上报次数等)。UE根据测量控制消息中的测量对象、报告配置去执行测量和评估，并根据测量结果生成测量报告上报给网络侧。对于事件触发的测量任务，当测量对象满足事件的准入条件(比如测量对象信号质量优于门限)的持续时间等于或大于TTT(Time To Trigger，触发时间)时才被认为是满足事件触发条件的测量对象。当有测量对象满足事件的触发条件后，上报测量报告给网络侧。
为了向移动用户提供更高的数据速率，高级长期演进系统(Long Term Evolution Advance，简称LTE-A)提出了载波聚合技术(Carrier Aggregation，简称CA)，其目的是为具有相应能力的UE提供更大宽带，提高UE的峰值速率。LTE中，系统支持的最大下行传输带宽为20MHz，载波聚合是将两个或者更多的分量载波(Component Carriers，简称CC)聚合起来支持大于20MHz，最大不超过100MHz的传输带宽。引入载波聚合技术后，处于连接状态的UE可以同时通过多个分量载波(CC，Component Carriers)与源基站 进行通信，引入CA技术后，还引入了主服务小区(Pcell，Primary Cell)和辅服务小区(Scell，Secondary Cell)。
由于频谱资源的匮乏，以及移动用户的大流量业务的激增，采用高频点如3.5GHz进行热点覆盖的需求日益明显，采用低功率的节点成为新的应用场景，为的是增加用户吞吐量和增强移动性能。但是由于高频点的信号衰减比较厉害，小区的覆盖范围比较小，并且与现有的小区不共站点，目前不少公司和运营商都倾向于寻求一种新的增强方案，双连接(Dual Connectivity)就是其中之一。双连接下终端可以同时与两个以上的网络节点保持连接，但是控制面连接只与其中一个小区比如宏小区有连接。终端的多个服务节点是多个基站，基站之间的时延不可忽略。比如，一个网络节点是宏基站称为MeNB，另外一个网络节点是小小区基站称为SeNB。
随着数据业务的快速增长，在不久的将来，授权频谱将不能承受如此巨大的数据量；所以LTE运营商考虑在非授权频谱资源(Unlicensed Carrier)中部署LTE，通过非授权频谱来分担授权载波中的数据流量。非授权载波(免授权频谱)是指在满足政府部门(如，国家无线电管理委员会)有关规定(无线电管制)下，不需要授权就能直接使用的频谱(或载波)。例如，微波炉、遥控玩具飞机、无线鼠标、无线键盘、高保真无线上网(Wireless Fidelity，WiFi)等都使用了非授权载波。在有的情况下，非授权载波需要通过竞争才能使用。如果基站(包括WiFi接入点)没有竞争到资源，则不能使用非授权载波。非授权载波和授权载波可以通过载波聚合的方式使用，也可以通过双连接的方式使用，非授权载波一般作为数据传输的补充，即授权载波作为主服务小区，非授权载波作为辅服务小区。
非授权载波资源有很大的特殊性和随机性，在此场景下，需要终端上报接收到的所有信号强度指示(RSSI，Received Signal Strength Indication)，在一定程度反映了非授权载波上的忙闲程度，辅助基站进行资源管理，如载波信道选择等，上报的内容包含采样RSSI的平均值，以及采样RSSI高于某指定门限的比例值，但是由于非授权载波环境下，非授权载波上的导频资源需要通过竞争才能获取使用，包括基站(eNB)发送的用于终端进行RRM(Radio Resource Management，无线资源管理)测量的指定相关信号，如CRS (Cell-specific Reference Signal，小区专有导频)、CSI-RS(Channel State Information-Reference Signal，信道状态信息测量导频)等，如果资源竞争失败，用于测量的指定相关信号则无法发送，终端无法测量到非授权载波上的导频信号强度和质量。如果只是上报上述RSSI的平均值/高于某指定门限的比例值的内容，基站仍然不能获得足够准确可靠的测量结果作为参考，导致基站不能根据可靠准确的测量报告进行合理的判决，严重时会产生通话中断或者用户通讯服务体验下降。
针对相关技术中的上述问题，目前尚未有效的解决方案。

本发明的实施方式
下文中将参考附图并结合实施例来详细说明本申请。需要说明的是，在 不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
实施例一
在本实施例中提供了一种非授权载波的测量上报方法，图1是根据本发明实施例的非授权载波的测量上报方法的流程图，如图1所示，该方法包括如下步骤：
步骤S102，接收基站发送的测量控制消息，其中，测量控制消息中携带指示信息，指示信息用于指示需要测量的非授权载波；
步骤S104，在指示信息指示的非授权载波上测量来自不同目标小区的多个导频信号，并将导频信号的测量结果上报给空口协议层层三；
步骤S106，在空口协议层层三记录与导频信号的测量结果分别对应的时间戳；
步骤S108，对记录的时间戳中两两相邻的时间戳之间的时间差值进行操作，其中，操作的结果用于指示基站在非授权载波上的占用情况以及终端能够接收测量到的导频信号情况；
步骤S110，上报操作的结果给基站。
可选地，在本实施例中，上述非授权载波的测量上报方法可以但不限于应用于LTE系统，还可以适用于所有需要通过竞争抢占才能使用非授权载波上无线资源的通讯系统。辅助基站(eNB)通过终端(UE)上报的非授权载波的测量的结果获取终端侧的无线状况，从而为终端做出更合理的无线资源选择决策。如获取到对非授权载波的占用情况，以实现通过被占用和相对空闲的时间图，来决策是否进行无线承载的增删。
可选地，在本实施例中，在接收基站发送的测量控制消息之前，上述方法还可以包括但不限于：UE在进行网络配置的某段时间内信号强度指示(RSSI，Received Signal Strength Indication)的测量过程中，收到基站(eNB)发射的导频信号经过物理层层一过滤后向空口协议层层三上报n个结果，分 别为R0，R1….Rn-1，其中，R0为非授权载波上收到eNB发射的导频信号经过物理层层一过滤后向空口协议层层三上报的第一个测量结果的时间，假设此时的时间为T0；R1为非授权载波上收到eNB发射的导频信号经过物理层层一过滤后向层三上报的第二个测量结果的时间，假设此时的时间为T1，以此类推，收到Rn-1的时间为Tn-1。
需要说明的是，由于eNB受到LBT(Listen Before Talk，先听后说)机制的约束，因而，基站发送上述用于测量的导频信号的时间是不确定的，从而导致UE测量到导频信号并上报给层三的时间在时间轴上也是不确定且是非周期的。因此，在本实施例中，上述物理层上报的测量结果中两两相邻的时间戳之间的时间差值，即，相邻两个时间戳之间的时间差值为：T1-T0，T2-T1，…Tn-1-Tn-2，时间差值的数值可以相同，也可以不相同。
上述时间差值从一定程度上可以反映出基站作为发送端，可以竞争获取到非授权载波资源的概率。比如，如果这些时间差值都很大，则表示基站侧竞争繁忙，基站可以竞争到非授权载波资源的概率也就较低，反之则表示基站侧无线资源(如非授权载波资源)较空闲。此外，如果这些时间差值的动态范围很大，则表示基站可以成功竞争到非授权载波资源的随机性很大，反之则比较规律。也就是说，基于时间差值，基站不仅可以获取终端侧的无线状况，还可以更加准确地分析出基站在所述非授权载波上的占用情况。
可选地，在本实施例中，终端所驻留的小区与非授权载波所覆盖的待测小区不同。其中，非授权载波所覆盖的待测小区与终端小区可以进行聚合，其中，上述聚合可以包括但不限于以下至少之一：载波聚合、双连接。
可选地，在本实施例中，上述对记录的时间戳中两两相邻的时间戳之间的时间差值进行操作可以包括但不限于以下至少之一：
1)、对时间差值进行取平均值操作，将时间差值的平均值作为操作的结果；例如，基于上述基站发射的n个导频信号为示例，时间差值的平均值为：Mean{(T1-T0)，(T2-T1)，……(Tn-1-Tn-2)}＝(Tn-1-T0)/(n-1)；
2)、对时间差值进行取方差值操作，将时间差值的方差值作为操作的结果；例如，基于上述基站发射的n个导频信号为示例，时间差值的方差值为：VAR{(T1-T0)，(T2-T1)，……(Tn-1-Tn-2)}；
3)、对时间差值进行统计操作，将时间差值小于或等于第一预定阈值的低延时采样数量作为操作的结果；例如，基于上述基站发射的n个导频信号为示例，第一预定阈值为Thresh-1，则统计上述时间差值中超过基站配置的第一预定阈值Thresh-1的个数。
需要说明的是，终端对测量到的导频信号经过物理层层一过滤后，将上报层三这些导频信号的测量结果，如有效采样值，并将获取到的每一个有效采样值的时间记录为与对应的一个导频信号的时间戳。
通过本申请提供的实施例，终端接收基站发送的测量控制消息，并根据测量控制消息中用于指示需要测量的非授权载波的指示信息的指示测量非授权载波上的多个导频信号，并将导频信号的测量结果上报给层三；在层三记录与导频信号的测量结果分别对应的时间戳；对记录的时间戳中两两相邻的时间戳之间的时间差值进行操作，以得到用于指示基站在非授权载波上的占用情况的操作的结果，并将该操作的结果上报给基站。从而便于基站结合终端上报的操作结果做出更加准确可靠的决策，进而解决相关技术中基站无法准确做出合理的判决所导致的掉话问题。
作为一种可选的方案对记录的时间戳中两两相邻的时间戳之间的时间差值进行操作包括以下至少之一：
1)、对时间差值进行取平均值操作，将时间差值的平均值作为操作的结果。
结合以下示例进行说明，例如，终端驻留在小区1，小区1的工作频点是f1，在小区1上发起无线资源控制协议(RRC，Radio Resource Control)连接建立，RRC连接建立过程完成后，终端进入连接态。进一步，终端接收到基站发送的测量控制消息中的指示信息指示测量非授权载波，其中，非授权载波的频点是f2。
假设在T1时物理层上报f2的信号给层三，并记录下时间戳T1；在T2时物理层上报f2的信号给层三，并记录下时间戳T2，其中，T2与T1的时间差值是80ms。在T3时物理层上报f2的信号给层三，并记录下时间戳T3；T3与T2的时间差值是40ms。在T4时物理层上报f2的信号给层三，并记录下时间戳T4；T4与T3的时间差值是40ms。在T5时物理层上报f2的信号 给层三，并记录下时间戳T5；T5与T4的时间差值是40ms。
在测量控制消息所指示的对f2进行RSSI测量的测量结束时刻到达时，终端将所有物理层上报的f2在RSSI测量后得到的时间差值进行取平均值操作。即，一共收到5个导频信号的时间戳，有4个时间差值，分别为80ms，40ms，40ms，40ms，平均值为50ms，则可以上报上述操作的结果平均值50ms。此外，计算高于指定门限值Thresh的比例，假设此时为4/5＝0.8，则还可以向基站上报高于指定门限值Thresh的比例0.8，以及RSSI的平均值。
2)、对时间差值进行取方差值操作，将时间差值的方差值作为操作的结果。
假设在T1时物理层上报f2的信号给层三，并记录下时间戳T1；在T2时物理层上报f2的信号上报给层三，并记录下时间戳T2，其中，T2与T1的时间差值是30ms。在T3时物理层上报f2的信号上报给层三，并记录下时间戳T3；T3与T2的时间差值是50ms。在T4时物理层上报f2的信号上报给层三，并记录下时间戳T4；T4与T3的时间差值是55ms。在T5时物理层上报f2的信号上报给层三，并记录下时间戳T5；T5与T4的时间差值是35ms。在T6时物理层上报f2的信号上报给层三，并记录下时间戳T6；T6与T5的时间差值是70ms。
在测量控制消息所指示的对f2进行RSSI测量的测量结束时刻到达时，终端将所有物理层上报的f2在RSSI测量后得到的时间差值进行取方差值操作。即，一共收到6个导频信号的测量时间，有5个时间差值，分别为30ms，50ms，55ms，35ms，70ms，方差值为257.5ms，则可以上报上述操作的结果方差值257.5ms。此外，计算高于指定门限值Thresh的比例，假设此时为4/6＝0.67，则还可以向基站上报高于指定门限值Thresh的比例0.67，以及RSSI的平均值。
3)、对时间差值进行统计操作，将时间差值小于或等于第一预定阈值的低延时采样数量作为操作的结果。
假设在T1时物理层上报f2的信号上报给层三，并记录下时间戳T1；在T2时物理层上报f2的信号上报给层三，并记录下时间戳T2，其中，T2与T1的时间差值是30ms。在T3时上报给层三，并记录下时间戳T3；T3与T2 的时间差值是50ms。在T4时上报给层三，并记录下时间戳T4；T4与T3的时间差值是55ms。在T5时物理层上报f2的信号上报给层三，并记录下时间戳T5；T5与T4的时间差值是35ms。在T6时上报给层三，并记录下时间戳T6；T6与T5的时间差值是70ms。
在测量控制消息所指示的对f2进行RSSI测量的测量结束时刻到达时，终端将所有物理层上报的f2在RSSI测量后得到的时间差值进行取方差值操作。即，一共收到6个导频信号的时间戳，有5个时间差值，分别为30ms，50ms，55ms，35ms，70ms，其中低于或等于第一预定阈值50ms的个数为3。此外，计算高于指定门限值Thresh的比例，假设此时为4/6＝0.67，则还可以向基站上报高于指定门限值Thresh的比例0.67，以及RSSI的平均值。
通过本申请提供的实施例，通过上述至少一种操作获取对多个物理层上报给层三的测量结果中两两相邻的时间戳之间的时间差值进行操作的结果，将上述操作的结果上报给基站，以使基站利用更加准确可靠的结果做出更加准确的决策。
作为一种可选的方案，对记录的时间戳中两两相邻的时间戳之间的时间差值进行操作包括：
重复执行以下步骤，以得到时间差值集合，直至到达测量控制消息所指示的对导频信号进行测量的测量结束时刻或者评估时间窗关闭时刻：获取与当前测量结果对应的当前时间戳；获取在当前时间戳之后得到的下一个测量结果对应的下一个时间戳；获取当前时间戳与下一个时间戳的时间差值，并将时间差值记录到时间差值集合中；将下一个时间戳作为下一个当前时间戳；
对时间差值集合中的时间差值进行操作。
结合以下示例进行说明，假设终端当前测量到f2的RSSI上报给层三当前时间戳为T3，并记录下时间戳T3；则获取在T3之后的下一个时间戳T4，并获取T4与T3的时间差值，即，40ms。然后，将T3之后的下一个时间戳T4作为下一个当前时间戳，获取T4之后的下一个时间戳T5，以此类推，直至到达测量控制消息所指示的对导频信号进行RSSI测量的测量结束时刻。
通过本申请提供的实施例，通过获取相邻两次时间戳之间的时间差值，从而实现通过时间差值获取基站对非授权载波的占用情况，即，作为发送端 竞争到非授权载波资源的概率，以及成功竞争获取到非授权载波资源的规律性。
作为一种可选的方案，在指示信息指示的非授权载波上测量来自不同目标小区的多个导频信号包括：
根据测量控制消息测量导频信号的信号强度或质量；
在测量到的信号强度或质量大于第二预定阈值时，判断出测量到导频信号。
通过本申请提供的实施例，通过根据测量控制消息中指示信息的指示测量待测量的非授权载波的导频信号的信号强度或质量，在测量到的信号强度或质量大于一定阈值后，判断出测量到该导频信号。从而实现利用测量时间获取相邻导频信号的测量时间的时间差值来提高基站进行决策的准确性及可靠性。
结合以下实施方式进行描述。假设基站有提供了两个小区的覆盖，小区1(部署在授权载波上)工作频点是f1，小区3(部署在非授权载波上)工作频点是f2。小区1和小区3可以进行载波聚合。对于小区1与非授权载波的小区3通过双连接的方式进行聚合。
作为一种可选的实施方式，终端驻留在小区1上，并在小区1上发起RRC连接建立，RRC连接建立过程完成后，UE进入连接态，小区1即为PCell。
由于业务的需要，基站需要给UE配置载波聚合，网络侧发送含有测量控制消息信息的RRC消息给UE，其中包含一个测量任务是：测量非授权载波f2的RSSI的测量任务1，测量对象是载频f2，周期上报，上报1次。上报内容包含RSSI的平均值、RSSI高于指定门限比如Thresh的比例、收到的相邻两个导频信号的时间戳的时间差平均值。
终端收到该测量任务，立刻开始测量f2的RSSI，和相关导频信号的测量。
如图2所示，终端在非授权载波上测量到多个导频信号：
T1时，终端将测量到的f2的RSSI上报给层三，并记录下时间戳T1；
T2时，终端将测量到的f2的RSSI上报给层三，记录下时间戳T2，T2 与T1时间差值是80ms；
T3时，终端将测量到的f2的RSSI上报给层三，记录下时间戳T3，T3与T2时间差值是40ms；
T4时，终端将测量到的f2的RSSI上报给层三，记录下时间戳T4，T4与T3时间差值是40ms；
T5时，终端将测量到的f2的RSSI上报给层三，记录下时间戳T5，T5与T4时间差值是40ms；
达到测量RSSI的测量结束时刻，终端将所有物理层上报的f2的RSSI进行平均，另外，计算RSSI高于指定门限比如Thresh的比例，此时为4/5＝0.8，先后收到两个导频的测量结果(如有效采样值)的时间差值的平均值，一共收到5个导频相关有效采样值，有4个时间差值，分别为80ms，40ms，40ms，40ms，平均值为50ms，上报上述三个结果(RSSI的平均值、RSSI高于指定门限比如Thresh的比例0.8、收到的相邻两个导频信号的时间戳的时间差平均值50ms)给基站。
如果需要上报多次，上述步骤进行重复。
作为另一种可选的实施方式，终端驻留在小区1上，并在小区1上发起RRC连接建立，RRC连接建立过程完成后，UE进入连接态，小区1即为PCell。
由于业务的需要，基站需要给UE配置载波聚合，网络侧发送含有测量控制消息信息的RRC消息给UE，其中包含一个测量任务是：测量非授权载波f2的RSSI的测量任务1，测量对象是载频f2，周期上报，上报1次。上报内容包含RSSI的平均值、RSSI高于指定门限比如Thresh的比例、收到的相邻两个导频信号的时间戳的时间差方差值。
终端收到测量任务，立刻开始测量f2的RSSI，和相关导频信号的测量。
如图3所示，终端在非授权载波上测量到多个导频信号：
T1时，终端将测量到的f2的RSSI上报给层三，并记录下时间戳T1；
T2时，终端将测量到的f2的RSSI上报给层三，记录下时间戳T2，T2与T1时间差是30ms；
T3时，终端将测量到的f2的RSSI上报给层三，记录下时间T3，T3与 T2时间差是50ms；
T4时，终端将测量到的f2的RSSI上报给层三，记录下时间T4，T4与T3时间差是55ms；
T5时，终端将测量到的f2的RSSI上报给层三，记录下时间T5，T5与T4时间差是35ms；
T6时，终端将测量到的f2的RSSI上报给层三，记录下时间T6，T6与T5时间差是70ms。
达到测量RSSI的测量结束时刻，终端将所有物理层上报的f2的RSSI进行平均，另外，计算RSSI高于指定门限比如Thresh的比例此时为4/6＝0.67，先后收到两个导频的测量结果(如有效采样值)的时间差值的平均值，一共收到6个导频相关有效采样值，有5个时间差值，分别为30ms，50ms，55ms，35ms，70ms，方差值为257.5ms，上报上述三个结果(RSSI的平均值、RSSI高于指定门限比如Thresh的比例0.67或67％、收到的相邻两个导频信号的时间戳的时间差方差值257.5ms)给基站。
作为又一种可选的实施方式，终端驻留在小区1上，并在小区1上发起RRC连接建立，RRC连接建立过程完成后，UE进入连接态，小区1即为PCell。
由于业务的需要，基站需要给UE配置载波聚合，网络侧发送含有测量控制消息信息的RRC消息给UE，其中包含一个测量任务是：测量非授权载波f2的RSSI的测量任务1，测量对象是载频f2，周期上报，上报1次。上报内容包含RSSI的平均值、RSSI高于指定门限比如Thresh的比例、收到的相邻两个导频信号的时间戳的时间差值中低于或等于eNB配置的门限(此时为50ms)的个数。
终端收到测量任务，立刻开始测量f2的RSSI，和相关导频信号的测量。
如图3所示，终端在非授权载波上测量到多个导频信号：
T1时，终端将测量到的f2的RSSI上报给层三，并记录下时间戳T1；
T2时，终端将测量到的f2的RSSI上报给层三，记录下时间戳T2，T2与T1时间差是30ms；
T3时，终端将测量到的f2的RSSI上报给层三，记录下时间T3，T3与 T2时间差是50ms；
T4时，终端将测量到的f2的RSSI上报给层三，记录下时间T4，T4与T3时间差是55ms；
T5时，终端将测量到的f2的RSSI上报给层三，记录下时间T5，T5与T4时间差是35ms；
T6时，终端将测量到的f2的RSSI上报给层三，记录下时间T6，T6与T5时间差是70ms。
达到测量RSSI的测量结束时刻，终端将所有物理层上报的f2的RSSI进行平均，另外，计算RSSI高于指定门限比如Thresh的比例此时为4/6＝0.67，先后收到两个导频的测量结果(如有效采样值)的时间差值的平均值，一共收到6个导频相关有效采样值，有5个时间差值，分别为30ms，50ms，55ms，35ms，70ms，其中低于或等于指定门限(50ms)的个数为3，如图3所示，上报上述三个结果(RSSI的平均值、RSSI高于指定门限比如Thresh的比例67％、收到的相邻两个导频信号的时间戳的时间差值中低于或等于eNB配置的门限(此时为50ms)的个数3)给基站。
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根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，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，本申请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设备(可以是手机，计算机，服务器，或者网络设备等)执行本申请各个实施例所述的方法。

步骤S406，根据操作的结果执行资源配置操作，其中，资源配置操作包括以下至少之一：小区切换、小区重选、重配无线承载。
可选地，在本实施例中，上述非授权载波的配置方法可以但不限于应用于LTE系统，还可以适用于所有需要通过竞争抢占才能使用非授权载波上无线资源的通讯系统。辅助基站(eNB)通过终端(UE)上报的非授权载波的测量的结果获取终端侧的无线状况，从而为终端做出更合理的无线资源选择决策。其中，上述基站可以包括但不限于：当前基站或目标基站。
需要说明的是，在基站侧可以做的动作依赖于基站内部各种具体的策略实现，比如基于终端上报的测量结果，进行移动性小区切换(包括同频小区切换、异频小区切换、异系统切换)，数据无线承载的资源重配，载波聚合辅小区重选等等。通过结合本实施例中记载的终端上报的操作的结果进行综合评估处理，以使基站作出更加准确可靠的决策，从而保持终端正在进行的业务能够连续，用户通讯性能体验维持，系统资源效率能够保持高效等。
可选地，在本实施例中，根据操作的结果执行资源配置操作包括以下至少之一：
在操作的结果指示目标小区的无线资源空闲时，将终端当前的源非授权载波上辅服务小区切换到目标非授权载波上辅服务小区；
在操作的结果指示目标小区的无线资源空闲时，为终端重配无线承载；
在操作的结果指示目标小区的无线资源忙碌或者负荷重时，对终端进行源非授权载波上辅服务小区的删除或者去激活；或者，在操作的结果指示目标小区的无线资源空闲或负荷轻时，对终端进行非授权载波上辅服务小区的添加或者激活。
需要说明的是，上述小区切换可以包括但不限于以下至少之一：同频小区切换、异频小区切换、异系统切换。上述小区重选是载波聚合辅小区重选。 其中，在本实施例中，上述终端驻留的小区为主小区，非授权载波所覆盖的测量小区为辅小区，主小区和辅小区将进行聚合，聚合的方式包括以下至少之一：载波聚合、双连接。
实施例三
在本实施例中还提供了一种非授权载波的测量上报终端，该终端用于实现上述实施例及可选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。
图5是根据本发明实施例的非授权载波的测量上报终端的示意图，如图5所示，该终端包括：
接收单元502，设置为接收基站发送的测量控制消息，其中，测量控制消息中携带指示信息，指示信息用于指示需要测量的非授权载波；
测量单元504，设置为在指示信息指示的非授权载波上测量来自不同目标小区的多个导频信号，并将导频信号的测量结果上报给空口协议层层三；
记录单元506，设置为在空口协议层层三记录与导频信号的测量结果分别对应的时间戳；
操作单元508，设置为对记录的时间戳中两两相邻的时间戳之间的时间差值进行操作，其中，操作的结果用于指示基站在非授权载波上的占用情况以及终端能够接收测量到的导频信号情况；
上报单元510，设置为上报操作的结果给基站。
可选地，在本实施例中，上述非授权载波的测量上报终端可以但不限于应用于LTE系统，还可以适用于所有需要通过竞争抢占才能使用非授权载波上无线资源的通讯系统。辅助基站通过终端上报的非授权载波的测量的结果获取终端侧的无线状况，从而为终端做出更合理的无线资源选择决策。如获取到对非授权载波的占用情况，以实现通过被占用和相对空闲的时间图，来决策是否进行无线承载的增删。
可选地，在本实施例中，在接收基站发送的测量控制消息之前，还可以 包括但不限于终端在进行网络配置的某段时间内信号强度指示(RSSI，Received Signal Strength Indication)的测量过程中，收到基站发射的导频信号经过物理层层一过滤后向空口协议层层三上报n个结果，分别为R0，R1….Rn-1，其中R0为非授权载波上收到基站发射的导频信号经过物理层层一过滤后向空口协议层层三上报的第一个测量结果的时间，假设此时的时间为T0；R1为非授权载波上收到基站发射的导频信号经过物理层层一过滤后向层三上报的第二个测量结果的时间，假设此时的时间为T1，以此类推，收到Rn-1的时间为Tn-1。
需要说明的是，由于eNB受到LBT(Listen Before Talk，先听后说)机制的约束，因而，基站发送上述用于测量的导频信号的时间是不确定的，从而导致终端测量到导频信号并上报给层三的时间在时间轴上也是不确定且是非周期的。因此，在本实施例中，上述物理层上报的测量结果中两两相邻的时间戳之间的时间差值即，相邻两个时间戳之间的时间差值为T1-T0，T2-T1，…Tn-1-Tn-2，时间差值的数值可以相同，也可以不相同。
上述时间差值从一定程度上可以反映出基站作为发送端，可以竞争获取到非授权载波资源的概率。比如，如果这些时间差值都很大，则表示基站侧竞争繁忙，基站可以竞争到非授权载波资源的概率也就较低，反之则表示基站侧无线资源(如非授权载波资源)较空闲。此外，如果这些时间差值的动态范围很大，则表示基站可以成功竞争到非授权载波资源的随机性很大，反之则比较规律。也就是说，基于时间差值，基站不仅可以获取终端侧的无线状况，还可以更加准确地分析出基站在所述非授权载波上的占用情况。
可选地，在本实施例中，终端所驻留的小区与非授权载波所覆盖的待测小区不同。其中，非授权载波所覆盖的待测小区与终端小区可以进行聚合，其中，上述聚合可以包括但不限于以下至少之一：载波聚合、双连接。
可选地，在本实施例中，上述对记录的时间戳中两两相邻的时间戳之间的时间差值进行操作可以包括但不限于以下至少之一：
1)、对时间差值进行取平均值操作，将时间差值的平均值作为操作的结果；例如，基于上述基站eNB发射的n个导频信号为示例，时间差值的平均值为：Mean{(T1-T0)，(T2-T1)，……(Tn-1-Tn-2)}＝(Tn-1-T0)/(n-1)；
2)、对时间差值进行取方差值操作，将时间差值的方差值作为操作的结果；例如，基于上述基站eNB发射的n个导频信号为示例，时间差值的方差值为：VAR{(T1-T0)，(T2-T1)，……(Tn-1-Tn-2)}；
3)、对时间差值进行统计操作，将时间差值小于或等于第一预定阈值的低延时采样数量作为操作的结果；例如，基于上述基站发射的n个导频信号为示例，第一预定阈值为Thresh-1，则统计上述时间差值中超过基站配置的第一预定阈值Thresh-1的个数。
需要说明的是，终端对测量到的导频信号经过物理层层一过滤后，将上报层三这些导频信号的测量结果，如有效采样值，并将获取到的每一个有效采样值的时间记录为与对应的一个导频信号的时间戳。
通过本申请提供的实施例，终端接收基站发送的测量控制消息，并根据测量控制消息中用于指示需要测量的非授权载波的指示信息的指示测量非授权载波上的多个导频信号，并将导频信号的测量结果上报给层三；在层三记录与导频信号的测量结果分别对应的时间戳；对记录的时间戳中两两相邻的时间戳之间的时间差值进行操作，以得到用于指示基站在非授权载波上的占用情况的操作的结果，并将该操作的结果上报给基站。从而便于基站结合终端上报的操作结果做出更加准确可靠的决策，进而解决相关技术中基站无法准确做出合理的判决所导致的掉话问题。
作为一种可选的方案，操作单元508包括以下至少之一：
第一操作模块，设置为对时间差值进行取平均值操作，将时间差值的平均值作为操作的结果；
结合以下示例进行说明，例如，终端驻留在小区1，小区1的工作频点是f1，在小区1上发起无线资源控制协议(RRC，Radio Resource Control)连接建立，RRC连接建立过程完成后，终端进入连接态。进一步，终端接收到基站发送的测量控制消息中的指示信息指示测量非授权载波，其中，非授权载波的频点是f2。

在测量控制消息所指示的对f2进行RSSI测量的测量结束时刻到达时，终端将所有物理层上报的f2在RSSI测量后得到的时间差值进行取方差值操作。即，一共收到6个导频信号的测量时间，有5个时间差值，分别为30ms，50ms，55ms，35ms，70ms，方差值为257.5ms，则可以上报上述操作的结果方差值257.5ms。此外，计算高于指定门限值Thresh的比例，假设此时为4/6＝0.67，则还可以向基站上报高于指定门限值Thresh的比例0.67，以及RSSI的平均值。

在测量控制消息所指示的对f2进行RSSI测量的测量结束时刻到达时，终端将所有物理层上报的f2在RSSI测量后得到的时间差值进行取方差值操作。即，一共收到6个导频信号的时间戳，有5个时间差值，分别为30ms，50ms，55ms，35ms，70ms，其中低于或等于第一预定阈值50ms的个数为3。此外，计算高于指定门限值Thresh的比例，假设此时为4/6＝0.67，则还可以向基站上报高于指定门限值Thresh的比例0.67，以及RSSI的平均值。
通过本申请提供的实施例，通过上述至少一种操作获取对多个物理层上报给层三的测量结果中两两相邻时间戳之间的时间差值进行操作的结果，将上述操作的结果上报给基站，以使基站利用更加准确可靠的结果做出更加准确的决策。
作为一种可选的方案，操作单元508包括：
处理模块，设置为重复执行以下步骤，以得到时间差值集合，直至到达测量控制消息所指示的对导频信号进行测量的测量结束时刻或者评估时间窗关闭时刻：获取与当前测量结果对应的当前时间戳；获取在当前时间戳之后得到的下一个测量结果对应的下一个时间戳；获取当前时间戳与下一个时间戳的时间差值，并将时间差值记录到时间差值集合中；将下一个时间戳作为下一个当前时间戳；
第四操作模块，设置为对时间差值集合中的时间差值进行操作。
结合以下示例进行说明，假设终端当前测量到f2的RSSI上报给层三当前时间戳为T3，并记录下时间戳T3；则获取在T3之后的下一个时间戳T4，并获取T4与T3的时间差值，即，40ms。然后，将T3之后的下一个时间戳T4作为下一个当前时间戳，获取T4之后的下一个时间戳T5，以此类推，直至到达测量控制消息所指示的对导频信号进行RSSI测量的测量结束时刻。
