Description

一种双连接中功率余量报告的上报方法、装置和系统 技术领域
本发明涉及移动通信的双连接技术，尤其涉及一种双连接中功率余量报告的上报方法、装置和系统。
背景技术
长期演进(LTE)系统中，用户终端(UE)当前的发射功率不能超过UE最大发射功率，一般的，UE通过功率余量报告(PHR，Power Headroom Report)上报过程将UE最大发射功率与当前上行共享信道(UL-SCH，Uplink Shared Channel)和物理上行控制信道(PUCC，Physical Uplink Control Channel)的发射功率的差别通知演进的节点B(eNB)，eNB根据这个差别进行上行调度和链路适配，进一步决定是否进行功率控制(如减小发射功率或增加发射功率，以及需要进行调整的功率大小)以满足UE当前发射功率不能超过UE最大发射功率同时达到最优接收效果的要求。PHR上报过程是通过UE发送PHR的MAC CE给网络侧来完成的。当前技术中，触发UE上报PHR有以下几种情况：路损变化超过指定门限、周期上报定时器超时、PHR的配置发生改变、激活辅服务小区(Scell，Secondary Cell)、功率控制导致的功率回退超过指定门限。当前技术中PHR的触发和发送过程如图1所示，包括：
步骤101：触发UE上报PHR；
其中，触发UE上报PHR有以下几种情况：路损变化超过指定门限、周期上报定时器超时、PHR的配置发生改变、激活Scell、功率控制导致的功率回退超过指定门限。
步骤102：UE接收eNB发送的上行授权；
步骤103：UE向eNB上报PHR；
步骤104：eNB根据PHR确定对UE进行功率调整；
步骤105：eNB向UE发送功率调整的通知消息。
在LTE系统中，UE建立呼叫的过程包括：建立UE与eNB之间的控制面链路和用户面链路的过程、以及建立eNB与核心网之间的控制面链路和用户面链路的过程。UE的呼叫过程建立后，eNB与核心网之间的控制面数据通过eNB与核心网中的移动性管理实体(MME)之间建立的连接来承载，eNB与核心网之间的用户面数据通过eNB与核心网中的服务网关(SGW)之间建立的演进无线接入承载(ERAB，E-UTRAN Radio Access Bearer)来承载；而eNB与UE之间的用户面数据采用数据无线承载(DRB，Data Radio Bearer)来承载，每个DRB都配置有标识，控制面数据则采用信令无线承载(SRB，Signalling Radio Bearer)来承载，每个SRB都配置有标识。
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。终端的多个网络节点是多个eNB，eNB之间的时延不可忽略。比如一个网络节点是宏eNB称为MeNB，另外一个网络节点是小小区eNB称为SeNB。为了方便管理和减少调度的时延，在MeNB上存在主服务小区(Pcell，Primary Cell)和Scell，在SeNB上存在主辅服务小区(PScell，Primary Secondary Cell)和Scell。
双连接中，为了更好地进行eNB间的负荷均衡，并最大程度地优化小区资源，引入分割数据无线承载，双连接中，存在分割数据无线承载和非分割数据无线承载，非分割数据无线承载可以只存在于MeNB或SeNB，一共会有三种类型的数据无线承载，其中，只存在于MeNB上的数据无线承载简称MeNB承载，只存在于SeNB上的数据无线承载简称SeNB承载，同时存在于MeNB和SeNB上的数据无线承载简称分割(split)数据无线承载。在数据无线承载同时存在于MeNB和SeNB上的背景下，如何触发PHR的上报，尚未有公开的技术。

为了更好地理解本发明，下面结合具体实施例对本发明作进一步地描述。
实施例一
本实施例中，UE与小区1建立了连接，小区1为Pcell，建立有数据无线承载1，只存在于基站1上，是MeNB承载，上行下行都通过MeNB来发送，即通过小区1来发送，实现一种双连接中功率余量报告的上报方法如图8所示，包括：
步骤801：由于业务量增加，基站1根据测量报告，给UE增加基站2的小区4，即向UE发送小区4的配置信息，小区4为PScell，同时将数据无线承载1改为分割数据无线承载，即，数据无线承载1同时存在于基站1和基站2，上行发送通过基站1发送；
步骤802：UE收到小区4的配置信息，增加小区4并将数据无线承载1改为分割数据无线承载；
步骤803：当小区1的上行资源不够时，基站1确定将数据无线承载1的上行发送转换到基站2上，给基站2发送承载修改请求，可以同时携带数据无线承载1在基站1的相关配置信息，如上行配置信息；
步骤804：基站2收到承载修改请求，给数据无线承载1预留资源，向基站1回应承载修改响应，同意修改，可以同时携带数据无线承载1在基站2的相关配置信息，如上行配置信息；
步骤805：基站1收到基站2的承载修改响应，给UE发送承载修改命令，所述承载修改命令中包括上行发送转换指示信息，用于指示将数据无线承载1的上行发送从基站1转换到基站2，所述上行发送转换指示信息可以是一个指示位，或者是数据无线承载1在基站2的相关配置中的独立的信元；
步骤806：UE收到上行发送转换指示信息，将数据无线承载1的上行发送从基站1转换到基站2，同时触发基站1和基站2的PHR上报，在后续的上行授权中向基站1和基站2发送当前激活小区如小区1和小区4的PHR；
本实施例中，在步骤806之后，数据无线承载1的上行发送从基站2转换到基站1时，也触发基站1和基站2的PHR上报。
实施例二
UE与小区1建立了连接，小区1为Pcell，建立有数据无线承载1，只存在于基站1上，是MeNB承载，上行下行都通过MeNB上小区1来发送，实现一种双连接中功率余量报告的上报方法如图9所示，包括：
步骤901：由于业务量增加，基站1根据测量报告，给UE增加基站2的小区4，即向UE发送小区4的配置信息，小区4为PScell，同时将数据无线承载1改为分割数据无线承载，即数据无线承载1同时存在于基站1和基站2，并且，由于小区1的上行资源不够了，基站1同时将数据无线承载1的上行发送转换到基站2上，表现方式可以是通过一个指示位，或者通过数据无线承载1在基站2的相关配置中的独立的信元，作为上行发送转换指示信息发送给UE；
步骤902：UE收到小区4的配置信息，增加小区4，并将数据无线承载1改为分割数据无线承载，并将数据无线承载1的上行发送从基站1转换到基站2；
步骤903：UE发现数据无线承载1的上行发送从基站1转换到基站2，于是触发基站1和基站2的PHR上报，在后续的上行授权中向基站1和基站2发送当前激活小区如小区1和小区4的PHR；
本实施例中，如果数据无线承载1变成建立在基站2上，即SeNB上，上行下行都通过SeNB上小区4来发送，将数据无线承载1改为分割数据无 线承载，同时上行发送由基站2转换到基站1的过程与上述步骤类似，不再重复描述。
上述步骤903，由于基站2是新的上行数据发送节点，因此UE可以只触发基站2的PHR，在后续的上行授权中向基站2发送当前激活小区如小区1和小区4的PHR。
实施例三
UE与小区1建立了连接，小区1即为Pcell，另外增加了基站2的小区3，建立有数据无线承载1，同时存在于基站1和基站2，是分割数据无线承载，上行发送通过基站2来发送，实现一种双连接中功率余量报告的上报方法如图10所示，包括：
步骤1001：基站1根据测量报告，由于基站2的小区3信号质量变差，基站2的小区4信号质量变好，基站1确定将小区3删除，增加小区4；
步骤1002：UE收到小区3的删除命令和小区4的增加命令，删除小区3，增加小区4，并且，数据无线承载1的上行是通过基站2来发送，但是由小区3变成了小区4，因此触发基站2的PHR上报，在后续的上行授权中向基站2发送当前激活小区如小区1和小区4的PHR；
步骤1003：基站1根据测量报告，获知小区4信号质量变差，基站1确定将小区4删除，给UE发送删除小区4的命令
步骤1004：UE收到小区4的删除命令，执行删除小区4，数据无线承载1从分割承载变成MeNB承载，上行发送也从基站2变成基站1，因此触发基站1的PHR上报，在后续的上行授权中向基站1发送当前激活小区如小区1的PHR。
上述步骤1002中，如果不删除小区3，直接增加小区4，基站2上变成小区3和小区4的载波聚合，此时，因为上行发送由小区3变成小区3加上小区4，也是发生改变了，因此也触发基站2的PHR上报，在小区3 和小区4同时进行使用的情况下，删除小区4，上行发送也是发生了改变，也触发基站2的PHR上报。
本实施例之后，数据无线承载1的上行通过MeNB发送，当MeNB上小区发生改变，也相应触发基站2的PHR上报。
以上所述，仅为本发明的较佳实施例而已，并非用于限定本发明的保护范围，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
