具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
面对5G网络的各种需求，本发明实施例提出一种以用户为中心的协议 栈架构。该协议栈架构在继承4G协议栈架构优点的基础上，把小区(cell)和用户终端(UE)分离，实现以小区为单位的无线资源管理系统按照用户的空口需求提供恰当的无线资源的目的，以多层次集中分布(MLCD，Multi-level centralized and distributed)方式对小区级别和用户终端级别的计算分别进行分类，在匹配云技术大数据计算能力特点的基础上，实现5G以用户为中心的网络目标。
图1为本发明实施例以用户为中心的协议栈架构的示意图，如图1所示，UE1至UEn分别表示处于该基站覆盖区域内的第1用户终端至第n用户终端，n为大于1的自然数；Cell_controller表示小区控制模块，Cell_1至Cell_n分别表示第1小区至第n小区，Cell_2表示第2小区；从图1中可以看出，对于处于同一基站的覆盖区域内的每个用户终端，均可以使用各个小区的无线资源，也就是实现了小区和用户终端的分离。
在传统的无线通信网络中，无法根据用户的空口环境提供灵活空口(Hybrid PHY)，并且对于用户终端的小区切换流程，存在信令开销大、信令处理时延长等技术问题；针对上述技术问题，在上述记载的以用户为中心的新型协议栈架构的基础上，本发明实施例提出了一种配置无线资源的方法及基站和用户终端，能够极大地简化用户终端移动时的切换的信令流程时延，在兼容传统的切换方案的前提下进行了创新。
本发明实施例中，结合以用户为中心的协议栈架构，将小区和用户分离，结合MCD的管理方式，通过快速调度的方式改变空口链路，并且确保基站与核心网之间的高层链路不修改，从而降低了用户终端移动时由配置无线资源而产生的信令时延，提高了用户终端与基站之间的链路的可靠性。
第一实施例
本发明第一实施例提供了一种配置无线资源的方法，图2为本发明实施例的配置无线资源的方法的流程示意图，如图2所示，该流程包括：
步骤201：基站获取UE的实时位置信息，所述基站所覆盖的区域包括至少两个小区。
在实际实施时，UE可以实时获取自身的位置信息，并将自身的位置信息上报至相应的基站，如此，网络侧设备如基站便可以获取UE的实时位置信息；UE可以采用多种方式获取自身的位置信息，这里不再赘述。
这里，对基站的类型不作限制，例如，基站可以是3G网络的基站，也可以是4G网络中的演进型基站(eNB，Evolved Node B)。
步骤202：所述基站基于所述实时位置信息确定所述UE进行跨小区的移动时，利用自身的MAC层协议实体向所述UE的MAC层协议实体发送实现小区切换的无线资源配置信令。
可以理解的是，基站的覆盖区域至少包括两个小区；UE在上述基站的覆盖区域内移动时，可以在一个小区内移动，也可以从上述基站的覆盖区域的一个小区移动至另一个小区。
在现有技术中，当UE从一个小区移动至另一个小区时，会控制UE启动小区切换流程，基站向UE通过RRC信令发送小区切换命令，使UE的服务小区从一个小区切换至另一小区，例如，在长期演进(LTE，Long Term Evolution)系统的小区切换方案中，UE到核心网的整个链路的切换均采用RRC信令进行控制；这里，UE进行的跨小区的移动可以是在同一个基站的覆盖区域内的跨小区的移动，还可以是在两个不同基站间进行的跨小区的移动。
可以看出，在现有的小区切换方案中，UE到核心网的整个链路的切换均在一套信令控制下实现。
相对地，在本发明实施例中，当UE在从同一个基站的覆盖区域的一个小区移动至另一个小区时，基站利用自身的MAC层协议实体向所述UE的MAC层协议实体发送实现小区切换的无线资源配置信令，并保持基站与核 心网之间的无线链路不变。
当UE从在两个不同的基站间进行跨小区的移动时，即，UE从一个基站的小区移动至另一个基站的小区时，利用自身的MAC层协议实体向所述UE的MAC层协议实体发送实现小区切换的无线资源配置信令，并利用RRC信令发起对基站与核心网之间的无线链路的切换。
可以看出，本发明实施例通过MAC层协议实体的快速空口控制，大大降低了UE触发切换过程的频率，降低了空口信令的处理时延，提高了空口的可靠性，简化了信令流程的复杂程度。
本步骤中，在向所述UE的MAC层协议实体发送实现小区切换的无线资源配置信令前，还可以配置所述UE的服务小区；进一步地，还可以为UE配置上述服务小区能够使用的无线资源，也就是说，在上述记载的所配置的服务小区能够使用的无线资源中，选取无线资源配置给UE；例如，基站所覆盖的区域包括小区1、小区2和小区3，在向所述UE发送无线资源配置信令前，可以将小区1、小区2或小区3配置为UE的服务小区；也可以将小区1、小区2或小区3中的无线资源配置给UE。
这里，服务小区能够使用的无线资源可以是服务小区能够使用的信道资源等等。
可以理解的是，在上述基站所覆盖的区域中，至少一个小区与UE之间存在无线链路(RL，Radio Link)，服务小区与UE之间的无线链路不仅可以传输信令，也可以传输用户数据，而其他小区与UE之间的无线链路不能传输用户数据。
具体地，上述记载的配置所述UE的服务小区包括：获取UE与基站之间的信道状态数据，基于所述的信道状态数据配置UE的服务小区。
进一步地，UE与基站之间的信道状态数据可以包括UE与基站所覆盖的区域中的每个小区之间的信道状态数据；信道状态数据可以包括以下参 数中的至少一种：信道状态信息(CSI，Channel State Information)、参考信号接收功率(RSRP，Reference Signal Receiving Power)、接收的信号强度指示(RSSI，Received Signal Strength Indication)、信干噪比(SINR，Signal to Interference plus Noise Ratio)、信道质量指示(CQI，Channel Quality Indicator)。
在实际实施时，UE可以实时监测UE与基站之间的信道状态数据，并向基站上报相应的信道状态数据，这里，UE与基站之间的信道状态数据可以是UE对应的各种空口质量监测参数。
这里，对基于所获取的信道状态数据配置UE的服务小区的实现方式不作限制，例如，可以在所获取的各个小区与UE之间的无线链路中，选取信道质量最好的无线链路，将选取的无线链路对应的小区配置为UE的服务小区。
本步骤中，在向所述UE的MAC层协议实体发送实现小区切换的无线资源配置信令之前，还可以将与所述UE建立无线链路的各个小区组成UE的激活小区集合；可以看出，UE的激活小区集合的小区的个数大于等于1。
下面分两种情况说明向UE发送无线资源配置信令的实现方式。
第一种情况：为UE配置的服务小区在UE的激活小区集合中。
基站向UE的MAC层协议实体发送的无线资源配置信令为：重配置所述UE与为所述UE配置的服务小区之间的无线链路的信令；这里，重配置所述UE与为所述UE配置的服务小区之间的无线链路的目的在于：使所述UE与为所述UE配置的服务小区之间的无线链路可以传输信令和用户数据。
例如，基站所覆盖的区域包括小区1、小区2和小区3，这三个小区与UE之间均存在无线链路，小区1为UE的初始服务小区，小区2是为UE配置的服务小区，可以理解的是，小区1与UE之间的无线链路可以用于传 输信令和用户数据，小区2与UE之间的无线链路不能用于传输用户数据；此时，基站需要向UE发送重配置小区2与UE之间的无线链路的信令，以使小区2与UE之间的无线链路可以传输信令和用户数据。
进一步地，若为UE配置的服务小区在UE的激活小区集合中，且为UE配置的服务小区并非UE的初始服务小区，则在UE的激活小区集合中删除UE的初始服务小区，进而实现对UE的激活小区集合的更新。
例如，基站所覆盖的区域包括小区1、小区2和小区3，这三个小区与UE之间均存在无线链路，即，小区1、小区2和小区3均在UE的激活小区集合中；区1为UE的初始服务小区，小区3是为UE配置的服务小区，此时，需要在UE的激活小区集合中删除小区1。
第二种情况：为UE配置的服务小区不在UE的激活小区集合中。
基站向UE的MAC层协议实体发送的无线资源配置信令为：建立UE与为UE配置的服务小区之间的无线链路的信令；建立UE与为UE配置的服务小区之间的无线链路的目的在于：使UE与为UE配置的服务小区之间的无线链路可以传输信令和用户数据。
例如，基站所覆盖的区域包括小区1、小区2和小区3，其中，小区1、小区2与UE之间均存在无线链路，小区3与UE之间不存在无线链路；小区1为UE的初始服务小区，小区3是为UE配置的服务小区，此时，基站需要向UE发送建立小区3与UE之间的无线链路的信令，以使小区3与UE之间的无线链路可以传输信令和用户数据。
需要说明的是，对于上述任意一种情况，在为UE配置的服务小区并非UE的初始服务小区，可以删除UE述UE的初始服务小区之间的无线链路。
步骤203：UE确定自身进行跨小区的移动时，利用自身的MAC层协议实体接收实现小区切换的无线资源配置信令。
示例性地，UE的MAC层协议实体确定接收到的无线资源配置信令是 重配置UE与为UE配置的服务小区之间的无线链路的信令时，将UE与为UE配置的服务小区之间的无线链路配置为具有以下功能：传输信令及用户数据；
UE的MAC层协议实体确定接收到的无线资源配置信令是建立UE与为UE配置的服务小区之间的无线链路的信令时，向UE配置的服务小区发送建立无线链路的请求，以使所建立的无线链路可以传输信令和用户数据
本发明实施例中，基站在向UE发送无线资源配置信令时，无线资源配置信令可以由基站的无线资源控制(RRC，Radio Resource Control)层协议实体生成，也可以由基站的媒介访问控制(MAC，Medium Access Control)层协议实体生成，下面分别进行说明。
1)基站的RRC层协议实体生成无线资源配置信令，将生成的无线资源配置信令发送至基站的MAC层协议实体，之后，基站的MAC层协议实体向UE的MAC层协议实体发送无线资源配置信令，UE的MAC层协议实体确认接收无线资源配置信令后，向UE的RRC层协议实体转发无线资源配置信令，从而实现基站和UE的RRC层协议实体之间的通信。
2)基站的MAC层协议实体向UE的MAC层协议实体发送无线资源配置信令，UE的MAC层协议实体确认接收无线资源配置信令，实现基站和UE的MAC层协议实体之间的通信。
进一步地，在UE基于接收的无线资源配置信令进行资源配置后，如果需要UE发起上行同步过程，基站和UE的MAC层协议实体通过交互完成上行同步控制过程。
可以看出，本发明实施例中，通过基站和UE的MAC层协议实体的快速空口控制，降低了配置无线资源时的信令时延。
需要说明的是，在UE从一个基站的覆盖区域移动至另一个基站的覆盖区域时，需要启动小区切换流程；小区切换流程可以沿用现有的小区切换 流程，这里不再赘述。
应用本发明第一实施例的配置无线资源的方法，基站获取用户终端UE的实时位置信息，所述基站所覆盖的区域包括至少两个小区；所述基站基于所述实时位置信息确定所述UE进行跨小区的移动时，向所述UE的MAC层协议实体发送实现小区切换的无线资源配置信令；如此，通过MAC层的快速空口控制，降低了UE触发切换过程的频率，降低了为UE配置无线资源时的空口信令的处理时延，提高了空口的可靠性，简化了信令流程的复杂程度。
另外，本发明实施例可以支撑各种高实时性协作化需求的方案，具有很好的扩展性，能够快速支撑海量用户，兼容性好，能够兼容3G/4G/5G网络。
第二实施例
为了能更加体现本发明的目的，在本发明第一实施例的基础上，进行进一步的举例说明。
在传统的小区切换方案中，当UE跨小区移动时，都要进行小区切换，并启动相应的小区切换流程。
图3为本发明实施例中配置无线资源的架构示意图，如图3所示，核心网(CN，Core Network)可以与至少一个基站进行通信，这里的基站可以是云基站(Cloud BS)；UE到基站的整个无线链路分为半静态链路(Semi-static link)、以及实时映射链路(Real-time Mapping Link)，其中，Semi-static link表示CN和基站之间的无线链路，对应着UE在MAC层以上的数据链路，Real-time Mapping Link表示基站与UE间的链路，对应着UE在空口的无线链路；基于对UE到基站的整个无线链路的两级划分方式，本发明实施例中可以分别采用RRC级别(RRC-level)的切换方案和MAC级别(MAC-level)的切换方案；这里，RRC级别的切换方案负责对Semi-static  link进行切换控制，MAC级别的切换方案负责Real-time Mapping Link在MAC层和物理层(PHY，Physical Layer)的空口的快速切换控制。
参照图3，在同一个Cloud BS的覆盖区域可以包括n个小区，n为大于1的自然数，这n个小区表示为Cell1至Celln；图3中，UEZ表示一个用户终端，当UEZ在通过一个基站覆盖的区域内的所有小区之间移动时，只需要进行MAC级别的实时映射(Real-time Mapping)切换方案，不需要进行RRC级别的Semi-static link的切换，即不需要对半静态链路做任何改变；只有UEZ从一个基站的覆盖区域内的小区移动到另一个基站的覆盖区域内的小区时，才需要网络侧触发RRC级别的Semi-static link的切换；在进行Semi-static link的切换的同时，MAC级别的Real-time Mapping Link的切换也需要同步完成，以实现用户在空口数据的交互。这里，RRC级别的Semi-static link的切换的方案可以沿用传统的LTE系统已有的高层信令控制流程和数据链路切换过程，但是，Real-time Mapping Link的切换需要采用MAC级别的切换方案；相对地，在现有的LTE系统的切换方案中，不需要区分Semi-static link和Real-time Mapping Link，所有链路在一套信令控制下进行切换。
在本发明实施例配置无线资源的方案中，针对UE的逻辑信道(logic channel)到传输信道-物理信道(transport channel-physical channeled)的映射采用实时映射的方式；具体地说，当UE进行跨小区的移动时，如果UE没有超出半静态链路能够支撑的范围(UE在移动过程中始终处于同一个基站的覆盖区域内)，只需要用实时映射的方式进行无线资源配置即可，不需要启动如4G协议栈的小区切换过程。
结合图3，网络侧设备(基站)的MAC层协议实体的通过UEZ上报的各种空口质量监测参数，并结合自身的运算，给UEZ配置本传输时间间隔(TTI，Transmission Time Interval)服务小区以及相应服务小区内能够使用 的无线资源(radio resource)，从而实现了逻辑信道首先到小区上，再到小区内载波，再到载波上承载的传输信道-物理信道的快速映射，在同一个基站内不需要像传统LTE协议栈要么只能进行小区切换才能实现小区间(inter cell)的调度(未采用载波聚合(CA，Carrier Aggregation)技术)，要么需要inter-cell MAC进行自组织(self organization)的方式实现小区间的调度(采用CA技术)。
可以看出，本发明实施例的无线资源配置方法降低了UE触发小区切换过程的频率，降低了空口信令的处理时延，提高了空口的可靠性，简化了信令流程的复杂程度，实现了了5G灵活空口的灵活控制。
下面结合附图，对UE在一个基站覆盖的区域内的所有小区之间移动时配置无线资源的方法进行详细说明。
图4为本发明实施例中配置无线资源的信令流程的第一示意图，如图4所示，该信令流程包括：
步骤a：基站(Base Station)RRC层协议实体生成无线资源配置信令，向基站MAC层协议实体发送无线资源配置信令，这里，无线资源配置信令可以以指示信令(Ho Ind)的形式进行发送。
步骤b：基站和UE的MAC层协议实体通过混合自动重传请求(HARQ，Hybrid Automatic Repeat reQuest)过程完成无线资源配置信令的收发和确认。
这里，在基站到UE的下行(DL)方向，基站和UE的MAC层协议实体可以通过物理下行控制信道命令(PDCCH order，Physical Downlink Control Channel order)、PDCCH或物理下行共享信道(PDSCH，Physical Downlink Shared Channel)实现信令的发送，在UE到基站的上行(UL)方向，可以通过物理上行链路控制信道(PUCCH，Physical Uplink Control Channel)或物理上行共享信道(PUSCH，Physical Uplink Shared Channel) 实现信令的发送。
步骤c：UE的MAC层协议实体在接收到无线资源配置信令后，向UE的RRC层协议实体发送无线资源配置请求(HO Req)。
步骤d：UE的RRC层协议实体接收到无线资源配置请求后，向UE的MAC层协议实体发送无线资源配置指示，这里，无线资源配置指示可以以指示信令(Ho Ind)的形式进行发送。
步骤e：UE的MAC层协议实体收到无线资源配置指示后，如果需要与基站进行上行同步，则向基站的MAC层协议实体发送上行同步信令(参见图4中的UL Time Alignment)。
步骤f：基站的MAC层协议实体向基站RRC层协议实体发送无线资源配置信令的确认应答信息(HO Ack)。
图5为本发明实施例中配置无线资源的信令流程的第二示意图，如图5所示，S_PHY(Source PHY)表示UE的初始服务小区的物理层协议实体，S_Intra Cell MAC(Source IntraCell MAC)表示UE的初始服务小区的MAC层协议实体，D_PHY(Destination PHY)表示为UE配置的服务小区的物理层协议实体，D_Intra Cell MAC(Destination IntraCell MAC)表示为UE配置的服务小区的MAC层协议实体，InterCell MAC表示小区间的MAC层协议实体，PDCP(Packet Data Convergence Protocol)/RLC(Radio Link Control)表示基站的分组数据汇聚协议/无线链路控制协议层实体，RRC表示基站的RRC层协议实体。
结合图5，可以分别针对两种实际场景来执行相应的步骤，这两种实际场景为场景1和场景2，其中，场景1中，为UE配置的服务小区(D_Cell)属于UE的激活小区集合(Cell Set)；在场景2中，为UE配置的服务小区(D_Cell)不属于UE的激活小区集合(Cell Set)。
针对场景1，向UE发送重配置所述UE与为所述UE配置的服务小区 之间的无线链路的信令，更新UE的激活小区集合，把UE的初始服务小区(S_Cell)从UE的激活小区集合删除。
针对场景2，需要UE与为所述UE配置的服务小区完成上下行同步，以实现UE与为所述UE配置的服务小区之间的数据传输。
参照图5，本发明实施例中配置无线资源的信令交互流程包括步骤1至步骤14；这里，对于场景1，执行步骤1至步骤6，对于场景2，执行步骤1、以及步骤7至步骤14。
图5所示的配置无线资源的信令交互流程包括以下步骤：
步骤1：基站的RRC层协议实体向InterCell MAC发送无线资源配置信令，无线资源配置信令的形式为指示信令(HO Ind)。
本步骤中，无线资源配置信令携带了用于指示D_Cell是否已经存在于UE的Cell Set中的指示信息；如果D_Cell已经存在于UE的Cell Set中，则该指示信息为场景1需要的信令指示信息；如果D_Cell不存在于UE的Cell Set中，则该指示信息为场景2需要的信令指示信息。
步骤2：InterCell MAC向D_IntraCell MAC(Destination IntraCell MAC：目的小区内MAC功能实体)发送更新UE的激活小区集合(Cell Update of UE)的指示消息。
也就是说，Cell Update of UE的指示消息用于指示更新UE的激活小区集合。
步骤3：D_IntraCell MAC基于所接收的指示消息，向D_PHY发送PDCCH order，D_IntraCell MAC发送的PDCCH order的具体格式可以由D_IntraCell MAC进行重新定义，D_IntraCell MAC发送的PDCCH order用于指示D_PHY通过PDCCH向UE发送无线资源配置信令。
步骤4：D_PHY通过PDCCH向UE发送无线资源配置信令，也就是说，D_PHY通过空口UE发送无线资源配置信令。
步骤5：InterCell MAC向基站的RRC层协议实体发送已完成无线资源配置的确认信息，InterCell MAC向基站的RRC层协议实体发送的确认信息的形式为确认应答信息(HO ACK)。
步骤6：基站的RRC层协议实体收到确认信息后，分别向InterCell MAC、S_Intra Cell MAC和S_PHY发送无线链路删除(RL Delete)消息，以释放在S_Intra Cell MAC和S_PHY上建立的UE上下文信息。
步骤7：InterCell MAC向S_Intra Cell MAC发送HO Info指示消息，用于S_Intra Cell MAC启动无线资源配置信令流程。
步骤8：基站的RRC层协议实体分别向InterCell MAC、D_Intra Cell MAC和D_PHY发送无线链路建立(RL Setup)消息，以在D_Intra Cell MAC和D_PHY上建立UE上下文信息。
步骤9：S_Intra Cell MAC向S_PHY发送PDCCH order；
本步骤中，PDCCH order的具体格式可以由S_IntraCell MAC进行重新定义，PDCCH order用于指示S_PHY通过PDCCH向UE发送无线资源配置信令。
进一步地，S_Intra Cell MAC还可以向S_PHY发送PDSCH order，PDSCH order用于指示S_PHY通过PDSCH向UE发送无线资源配置信令。
步骤10：S_PHY通过PDCCH向UE发送无线资源配置信令，也就是说，S_PHY通过空口UE发送无线资源配置信令。此时可以根据HO Info指示消息的大小决定是否需要使用PDSCH进行发送，如果是几个比特的指示消息，可以通过定义PDCCH Order的新格式完成；如果需要几十个字节，甚至更大的数据长度，则使用PDCCH+PDSCH和正常的HARQ过程发送；
这里的MAC PDU表示MAC层协议数据单元。
步骤11：UE从空口收到PDCCH或者PDCCH+PDSCH发送的无线资源配置信令后，向D_PHY和D_IntraCell MAC上发起上下行同步过程，该 过程可以是传统的随机接入过程，也可以是简化的随机接入过程，也或者不需要随机接入过程的其他同步过程。
步骤12：D_IntraCell MAC在完成上述上下行同步过程后向InterCell MAC发送已完成无线资源配置的确认信息，D_IntraCell MAC向InterCell MAC发送的确认信息的形式为确认应答信息(HO ACK)。
步骤13：InterCell MAC向基站的RRC层协议实体转发已完成无线资源配置的确认信息，InterCell MAC向基站的RRC层协议实体发送的确认信息的形式为确认应答信息(HO ACK)。
步骤14：基站的RRC层协议实体收到确认信息后，分别向InterCell MAC、S_Intra Cell MAC和S_PHY发送无线链路删除(RL Delete)消息，以释放在S_Intra Cell MAC和S_PHY上建立的UE上下文信息。
在图5中，步骤4、10、11中发送的信息是Uu口发送的消息(Msg in Uu)，步骤1、6、8、14中信令发送流程是基站内的信令交互流程(Interactive Msg in BaseStation)，步骤2、3、5、7、9、11、12、13中发送的信令为基站内传输的信令(Signaling in BaseStation)。
