技术领域
实施例涉及由无线网络中的电子设备执行的操作和通信。一些实施例涉及用于广域无线网络中无线电资源控制(RRC)参数的管理的操作。
背景技术
诸如3GPP长期演进(LTE)/高级长期演进(LTE-A)蜂窝电话网络标准(以下统称为“LTE”)之类的下一代移动网络的标准已经开始进行小小区(例如,微小区、毫微微小区或微微小区)部署的设计和实现。小小区部署可以在授权的或非授权的频谱中操作,并且通常提供几十米到公里级的操作范围;而宏小区部署通常具有几十公里的大得多的操作范围。
3GPPTR36.842讨论了多个LTE网络部署场景,包括其中不同载波频率(频率间)上的宏小区和小小区通过非理想的回程被连接的部署场景。因此,诸如演进的节点B(eNodeB或“eNB”)设备之类的网络设备必须定义哪些控制平面功能将由宏“锚”eNB执行和哪些功能将由微eNB或“协助”eNB执行。

具体实施方式
下面的描述和附图充分地示出了具体实施例,从而使得本领域的技术人员能够实施它们。其他实施例可以结合结构、逻辑、电气、过程和其他改变。一些实施例的部分和特征可以被包括在,或替代,其它实施例的这些部分和特征。权利要求中详细阐述的实施例包括这些权利要求的所有可用的等同物。
下面的技术和系统配置描述了被用来协助宏小区和小小区的操作参数的管理和协调的部署场景。具体地,下面描述了其中不同载波频率上的宏小区和小小区通过非理想的回程被连接的部署情景。下面的技术和配置被设计为通过小小区部署中的RRC参数的交换、调整和协调来更有效地操作小小区部署。
在其中不同载波频率(频率间)上的宏小区和小小区通过非理想的回程被连接的部署情景中,该部署的控制平面架构处在最初的标准开发阶段。与这些场景相关联的问题中的一个是确定哪些控制平面功能将由锚eNB执行和哪些功能将由协助eNB执行,以及这两个eNB将如何互相协调。例如,下面的技术描述了通过空闲模式和DRX参数配置的管理和部署,LTE网络中的空闲模式和DRX操作的协调场景。
在其中宏小区eNB和小小区eNB都具有到服务网关(S-GW)的单独的S1接口的情况下,没有协调,任一个UE想要知道网络上的具体UE何时是闲置(inactivity)的将是困难的。在不知道UE是否是闲置的情况下,eNB可能不能正确地释放连接或触发DRX模式。下面的技术描述了锚eNB与协助eNB之间的RRC闲置计时器控制和DRX参数交换的使用,从而使得eNB能够协调操作,例如,以便连接的UE可以功率最优化。
图1提供了多eNB网络环境100的图示,该多eNB网络环境100包括根据3GPPLTE网络标准操作的锚eNB102建立的宏小区104和协助eNB106建立的微小区/小小区108。eNB102和106建立了至少部分地重叠的覆盖区域来为用户设备(UE)110(例如,智能手机移动设备)提供网络覆盖,其中UE110被配置为通过收发器和(一根或多根)天线112来与eNB102和106进行通信。可以根据由3GPPLTE标准族建立的规范或其他建立的网络通信规范通过授权的或非授权的频谱发生网络通信。如所示出的,宏小区104的覆盖区域通常比微小区108的覆盖区域大,并且微小区108可以被部署在室内环境或被减小覆盖区域来提供附加网络覆盖和可操作性。
图2提供了3GPPLTE部署中的宏小区和微小区的用户平面架构200的图示。如所示出的,移动性管理实体通过相应的S1接口被连接至锚eNB212和协助eNB222。锚eNB212和协助eNB222各自操作包括分组数据汇聚协议(PDCP)层214和224、无线电链路控制(RLC)层216和226、和媒体访问控制(MAC)层218和228的各种协议层。锚eNB212和协助eNB222通过各自的LTE-Uu空中接口被连接至UE230。在UE230处,LTE协议栈用层2/层1协议层232和RRC协议层234的操作进行操作。
下面讨论确保各种协议参数在锚eNB和协助eNB之间被正确地同步的机制。例如,空闲模式和DRX模式操作可以取决于一个或多个参数,例如闲置计时器、功率偏好信息(PPI)的UE的指示、和不连续接收(DRX)参数。如果一个或多个这些参数不同步,则UE可能在活跃状态停留超过必要时间而浪费能量。例如,锚eNB可能不释放RRC连接直到协助eNB之后,因此,使得UE在RRC连接模式停留超过必要时间。这些操作的参数特别地可以在锚eNB和协助eNB各自具有到MME的单独的S1接口的具体的情况下被利用(例如,如图2所示出的)。
在下面的配置中,触发空闲模式、DRX模式、PPI和连接状态期间的PPI操作的功能在相应的锚eNB和协助eNB之间被划分,从而确保UE行为的简单和一致性。在现有的网络部署中,在锚eNB和协助eNB之间通常不存在针对决定RRC参数或启动空闲模式和DRX模式的协调。
在一些实施例中:
(1)UE可以将锚eNB和协助eNB通知给锚eNB和协助eNB中的一个或两者,以便它们可以互相交换信息。
(2)特定UE的RRC闲置计时器可以在锚eNB和协助eNB之间通过eNB之间的Xx(例如,X1,X2,X3)接口被交换。
(3)针对每一个UE,只有一个RRC闲置计时器可以被使用,如锚eNB和协助eNB之间所协商的。

下面提供被执行用于将设备在连接的和空闲的状态之间进行转换的操作,和DRX参数的选择和交换上的附加细节。
协调锚eNB和协助eNB的RRC闲置计时器
RRC连接释放操作可以基于由锚eNB和协助eNB维持的RRC闲置计时器被协调,从而将设备从连接状态转变至空闲状态。当UE连接至锚eNB和协助eNB两者时,仅当UE的RRC连接被两个eNB释放,它才可以移动至空闲模式。为了做到这样,锚eNB和协助eNB需要在相互之间协调RRC闲置计时器的值。存在若干方法可以实现它。
在一个示例中,RRC闲置计时器值在锚eNB和协助eNB之间被交换。这在图3中被更详细地描述,图3示出了网络与用户设备之间的流程300,流程300指示用于调整的一组新RRC参数的选择和部署。
如流程300所描述的,锚eNB302和协助eNB304被配置为建立用于空闲模式的单组RRC参数。首先,UE可以在锚eNB和协助eNB之间共享关于锚eNB和协助eNB的信息。在一些示例中,这始于由UE306将关于协助eNB304的信息传递给锚eNB302(操作312)。在其他示例中,UE可以将关于锚eNB的信息传递给协助eNB。根据这个信息,锚eNB和协助eNB304能够对另一者进行定位,并且能够使用eNB到eNB的接口进行通信。例如,公共RRC计时器的协商可以通过锚eNB和协助eNB之间的Xx(例如,X1,X2,X3)接口来完成。
接着,锚eNB和协助eNB互相协调来决定RRC闲置计时器的值。这可以包括提供从锚eNB302发送至协助eNB304的空闲模式参数请求(操作314)和响应于该参数请求从协助eNB304接收偏好的RRC参数(操作316)。根据这个信息,锚eNB302传递用于在锚eNB302和协助eNB304处使用的单个RRC参数集(操作318),该单个RRC参数集在eNB到eNB的接口上被传递。用于协调和传递单个参数集或单独的值的其他技术也可以被使用。
最后,锚eNB302将单个RRC参数集传递至UE306(操作320)。在网络设备之间可以决定只有锚eNB发送RRC连接释放消息,但是闲置计时器值在协助eNB和锚eNB之间被共享,或反之亦然。然而,在任何情况下,一个eNB可以使用参数值将RRC连接释放消息发送至UE306。
RRC闲置计时器的值可以基于两个eNB之间的协商,该协商可以选择在这些eNB处的最小的RRC闲置计时器。基于调整和协调操作,UE将更快地移动至完全的空闲模式(两个eNB的空闲模式)以节省UE电量。
锚eNB和协助eNB之间的DRX参数的选择和交换
为锚eNB和协助eNB维持单独的RRC连接的DRX状态可能导致UE在更长的时间周期内处于活跃状态(无论是锚eNB还是协助eNB),并且因此,导致在UE处的更高的设备功率消耗。在这里,单个DRX配置可以被选择用于部署在两个eNB上来减少这种情况的发生。
所选择的DRX配置可以取决于UE与锚eNB之间的和UE与协助eNB之间的流量流的QoS要求。DRX参数的协商和选择可以通过锚eNB和协助eNB之间的Xx(例如,X1,X2,X3)接口被执行。此外,如果UE如图2的用户平面架构200中所描述的与不同RRC实体连接,则经历不同设备RRC连接的DRX状态可能发生。
用于设置空闲模式计时器和DRX参数的过程本质上是相同的。因此,用于实现DRX参数同步化的过程将参考图3进行讨论。受到申请人的公开内容的启示的本领域的技术人员将意识到,空闲和DRX参数中的一个或两者可以被同步,并且如果两者都被同步,则图3的部分可以不被重复,从而节省消息。例如,如果空闲参数和DRX参数两者将在锚eNB和协助eNB之间被同步,则操作312可以不被重复。此外,参数请求314、偏好的参数316、到协助eNB318的参数集消息、和到UE320的参数集消息可以包括空闲模式和DRX参数两者。
如流程300所描述的,锚eNB302和协助eNB304被配置为建立用于DRX操作的单组RRC参数。首先,UE可以在锚eNB和协助eNB之间共享关于锚eNB和协助eNB的信息。在一些示例中,这始于由UE306将关于协助eNB304的信息传递给锚eNB302(操作312)。在其他示例中,UE可以将关于锚eNB的信息传递给协助eNB。根据这个信息,锚eNB和协助eNB304能够对另一者定位,并且能够使用eNB到eNB的接口进行通信。例如,公共RRC计时器的协商可以通过锚eNB和协助eNB之间的Xx(例如,X1,X2,X3)接口来完成。
接着,锚eNB和协助eNB互相协调来决定DRX参数的值。这可以包括提供从锚eNB302发送至协助eNB304的DRX参数请求(操作314)和响应于该参数请求从协助eNB304接收偏好的RRC参数(操作316)。根据这个信息,锚eNB302传递用于在锚eNB302和协助eNB304处使用的单个RRC参数集(操作318),该单个RRC参数集在eNB到eNB的接口上被传递。用于协调和传递单个参数集或单独的值的其他技术也可以被使用。
最后,锚eNB302将单个RRC参数集传递至UE306(操作320)。
图4描述了锚eNB同步空闲模式、DRX、或其他参数中的一个或多个的操作的流程图。在操作410处,eNB可以从UE接收关于协助eNB的消息。在操作420处,锚eNB可以发送消息,该消息询问协助eNB它的偏好的参数是什么。在操作430处,锚eNB可以从协助eNB接收偏好的参数。在操作440处,锚eNB可以确定RRC参数。在确定RRC参数时,eNB可以将协助eNB的偏好的参数的因素包括进去。在操作450处,锚eNB可以将偏好的参数发送至协助eNB。在操作460处,锚eNB可以将偏好的参数发送至UE。在一些示例中,协助eNB可以将偏好的参数发送至UE。偏好的参数可以包括DRX信息、空闲模式信息(例如,闲置计时器值)等等中的一个或多个。
向锚eNB和协助eNB提供PPI
仅将功率偏好信息(PPI)从UE发送至锚eNB和协助eNB中的一个将不会协助UE获得功率最优化的RRC配置。只有UE同时针对两个eNB处于低功率状态,UE才能节省电量。因此,在一些示例中,UE可以将PPI发送至两个eNB。可替代地,无论UE何时将PPI发送至具体eNB,该eNB可以通知另一个eNB关于该UE的PPI。此外,如果存在如图2的用户平面架构200中所示出的互相独立地操作的不同RRC实体,则经历不同RRC功率配置可能发生。
在一些示例中,图3中的锚eNB和协助eNB之间的控制消息可以包括从锚eNB和协助eNB中的一个或两者获得的PPI信息。
图5、6和7提供了PPI传输和功率优化的单个RRC参数集的选择的示例流程500、600和700。这些流程500、600和700可以被用作对图3中所描述的流程的修改,示出了最终的单组RRC参数在用户和网络设备之间可以被确定、定案和传递的附加的或替代的方式。
例如,图5示出了其中UE502将PPI传递至锚eNB504(操作510)的流程500。UE502也将PPI传递至协助eNB506(操作512)。锚eNB504和协助eNB506然后确定分别从各个eNB或从eNB中的一个(锚eNB504或协助eNB506)被传递至UE502的单个RRC参数集514。
作为另一个示例,图6示出了其中UE602将PPI传递至锚eNB604(操作610)的流程600。锚eNB604然后将PPI传递至协助eNB606(操作612)。协助eNB606然后确定单个RRC参数集614,并且将单个RRC传输集614中的这个信息传递至UE602。
作为另一个示例,图7示出了其中UE702将PPI传递至协助eNB706(操作710)的流程700。协助eNB706然后将PPI中继至锚eNB704(操作712)。锚eNB704然后确定单个RRC参数集714,并且将单个RRC参数集714中的这个信息传递至UE702。
在图5-7的示例的任一个示例中,只有一个eNB(锚eNB或协助eNB)可以被配置为发送RRC连接重新配置消息,而不是两个eNB都能发送相同的消息。这也将有助于减少通过空中交换的RRC消息参数的数量。
图8示出了由UE执行的用于调整宏小区部署和小小区部署(例如,由协助eNB操作的小小区部署)的RRC参数的技术的流程图800。在操作802处,UE将关于另一个eNB的信息传递至一个或多个协助eNB或锚eNB,从而使得eNB能够互相通信。在操作804处,UE可以从锚eNB或协助eNB接收一个或多个RRC参数。参数可以涉及RRC空闲模式计时器、DRX信息、PPI信息等等。在操作806处,UE可以使用在操作804处接收到的相同参数来在宏小区和小小区之中实现RRC层、DRX操作、或PPI操作。
