具体实施方式
下面结合附图及实施例对本公开再作进一步详细的描述。
在描述本公开实施例之前,先了解一下传统蜂窝网络及5G网络的相关信息。
传统的蜂窝网络的设计以小区为中心,也就是说,用户的接入/建立/去除、网络的覆盖、资源调度、移动性管理、信令控制、规划/优化等都是以独立小区来进行的。
而5G网络以高实时性同步协作要求为常态,面向大数据业务场景和密集节点的部署场景。从5G网络的能力指标可以看出,传统的网络架构已经无法满足5G时代的需求。如果仍采用传统的网络架构来达到5G网络的能力指标,则会使得小区内用户之间和小区之间的相互关系变得越来越复杂。同时,传统蜂窝网络公共信道的资源占用方式在5G高密度场景下已经成为网络的严重负担;并且传统蜂窝网络下的信令控制流程已无法满足5G快速、灵活变化的空口需求。从而使得传统蜂窝网络面对5G场景时,资源分配方面存在信令开销大、信令处理时延长等问题,从而造成无法满足用户更高服务需求的问题。
因此,针对5G网络中多样性的场景需要多样性的网络技术需求,5G无线网络的设计应该重新思考小区为中心的设计原则。
基于此,在本公开的各种实施例中:基站的去蜂窝单元利用所述基站自身获得的各小区资源,为UE分配相应的小区资源;基站的第一Cell_MAC单元基于为所述UE分配的小区资源,在为所述UE分配的小区资源上,为所述UE分配业务对应的无线资源;所述基站包含一个以上Cell_MAC单元;所述第一Cell_MAC单元为与为所述UE分配的小区资源对应的Cell_MAC单元。
需要说明的是,本文所用的第一、第二……仅表示不同的Cell_MAC单元,不对Cell_MAC单元的功能进行限定。
在实施例中,本实施例提供的基站1,如图1所示,该基站1包括:去蜂窝(No More Cell)单元11及第一Cell_MAC单元12;其中,
所述去蜂窝单元11,用于利用所述基站自身获得的各小区资源,为UE分配相应的小区资源;
第一Cell_MAC单元12,用于基于所述UE的传输特性,在为所述UE分配的小区资源上,为所述UE分配业务对应的无线资源;所述基站1包含一个以上Cell_MAC单元;所述第一Cell_MAC单元为与为所述UE分配的小区资源对应的Cell_MAC单元。
其中,实际应用时,所述基站1可以通过UE上报的方式、或者与其它基站交互的方式,获得各小区资源。
这里,实际应用时,针对5G网络的应用场景,本实施例的方案可以应用于宏基站+微基站的应用场景,相应地,此时,所述基站1获得的各小区资源为自身控制下的微基站对应的各小区资源。
所述去蜂窝单元11,具体用于:利用所述获得的各小区资源,基于全局或者局部最优收敛算法,为所述UE分配相应的小区资源。
在实施例中,所述去蜂窝单元11可以包括控制面信令处理模块11_1。该控制面信令处理模块11_1用于利用获得的各小区资源,基于全局或者局部最优收敛算法,为所述UE分配相应的小区簇资源;并且并基于全局或者局部最优收敛算法,并结合分配的小区簇资源,为所述UE分配相应的小区资源。
更具体地,在实施例中,如图2所示,所述控制面信令处理模块11_1可以包括:控制面信令处理子模块111以及集中调度子模块112;其中,
所述控制面信令处理子模块111,用于利用获得的各小区资源,基于全局或者局部最优收敛算法,为所述UE分配相应的小区簇资源;
所述集中调度子模块112,用于基于全局或者局部最优收敛算法,并结合分配的小区簇资源,为所述UE分配相应的小区资源。
也就是说,实际应用时,控制面信令处理子模块111以及集中调度子模块112可以合设在一起,即形成所述控制面信令处理模块11_1。
当所述UE需要进行业务时,所述去蜂窝单元11利用所述基站1自身获得的各小区资源,为UE分配相应的小区资源;相应地,第一Cell_MAC单元12基于所述UE的传输特性,在为所述UE分配的小区资源上,为所述UE分配业务对应的无线资源,以便后续利用分配的无线资源进行业务数据的传输。
其中,由于要实现所述去蜂窝单元11的功能,就要求去蜂窝单元11具有基于大数据云计算的能力。
分配的小区资源包括小区的功率、标识、信道等。
由于控制面信令处理子模块111利用获得的各小区资源,基于全局或者局部最优收敛算法,为所述UE分配相应的小区簇资源,要利用所有小区资源来分配相应的小区簇资源,数据量是海量的,所以该过程的处理速度比较慢(比如无线资源控制(RRC,Radio Resource Control)过程),而所述集中 调度子模块112是结合分配的小区簇资源,为所述UE分配相应的小区资源,数据量是比较少的,所以该过程的处理速度比较快。
在实施例中,进行所述业务过程中,所述去蜂窝单元11,还用于将来自核心网的业务数据进行传输处理;
所述第一Cell_MAC单元12,还用于利用为所述UE分配的无线资源,将传输处理后的业务数据通过空口发送给所述UE。
另外,在进行所述业务过程中,还需要传输除所述业务数据外的其它用户面数据,此时,所述第一Cell_MAC单元12,还用于将除所述业务数据外的其它用户面数据进行传输处理,并利用为所述UE分配的无线资源,将传输处理后的其它用户面数据通过空口发送给所述UE。
这里,所述传输处理是指:实现将核心网下发的用户面数据发送至所述UE所需要的各种处理,比如:压缩、加密等等。
所述业务数据可以是基于分组数据汇聚协议(PDCP,Packet Data Convergence Protocol)/无线链路控制(RLC,Radio Link Control)协议处理的用户面数据等;所述其它用户面数据可以是基于传输控制协议(TCP,Transmission Control Protocol)/因特网互联协议(IP,Internet Protocol)处理的高层用户面数据等。
如图3所示,所述去蜂窝单元11还可以包括:用户面数据包处理模块113,用于基于所述控制面信令处理子模块111的资源分配结果,将来自核心网的业务数据进行传输处理;
相应地,所述集中调度子模块112,用于基于全局或者局部最优收敛算法,并结合所述用户面数据包处理模块113的处理结果及分配的小区簇资源,为所述UE分配相应的小区资源,并将传输处理后的业务数据发送至所述第一Cell_MAC单元;
所述第一Cell_MAC单元12,用于收到所述集中调度子模块发送的业务数据后,将传输处理后的业务数据通过空口发送给所述UE。
在实施例中,在业务使用过程中,所述UE可能会发生位置移动,从而引发了小区切换,在这种情况下,当所述UE由于位置移动而发生了小区切换时,所述控制面信令处理子模块111,还用于利用获得的各小区资源,基于 全局或者局部最优收敛算法,重新为所述UE分配相应的小区簇资源;
相应地,如图4所示,所述集中调度子模块112,用于基于全局或者局部最优收敛算法,并结合重新分配的小区簇资源,为所述UE重新分配相应的小区资源;
所述第二Cell_MAC单元13,用于利用基于所述UE的传输特性,在重新为所述UE分配的小区资源上,为所述UE分配业务对应的无线资源;并利用为所述UE分配的无线资源,将传输处理后的业务数据通过空口发送给所述UE;所述第二Cell_MAC单元13为与重新为所述UE分配的小区资源对应的Cell_MAC单元。
需要说明的是:在上述实施例中,当所述控制面信令处理子模块111和集中调度子模块112合设在一起,形成所述控制面信令处理模块11_1时,由所述控制面信令处理模块11_1执行所述控制面信令处理子模块111和集中调度子模块112的功能。
从上面的描述中可以看出,本公开实施例的方案,对于基站,是一种去蜂窝(No More Cell)的设计思路,采用分层集中无线接入控制、实现跨接入点的快速/慢速资源调度、协调和切换。
具体地,以网络侧必须的无线资源管理单位(小区)为单位,集中整个网络(比如基站自身控制的所有微基站)的资源控制和协调功能,这种资源控制和协调功能主要包括无线资源管理(RRM,Radio Resource Management)和媒体访问控制(MAC,Media Access Control)的控制和协调功能,这种控制和协调作功能尤其适合应用在对跨小区的慢速控制(比如RRC流程等),比如系统信息下发、标识分配、大范围之间的移动性切换等,从而实现跨小区的空口实时性同步的实时性协作。
基于上述基站1中各单元功能的描述,可以得到如图5所示的网络架构示意图。如图5所示,基站1采用去蜂窝的基本思想,通过去蜂窝单元11将整个网络(比如基站自身控制的所有微基站)的小区资源,集中进行控制和协调,而把空口快速控制的功能下放到图5中所示基站的Cell_MAC单元,也就是说,各Cell_MAC单元主要实现两个功能:对于下面(UE),为灵活空口提供高实时性地控制,对于上面(去蜂窝单元),为大集中的控制面提供 相应的服务,以使去蜂窝单元实现自身的功能。
换句话说,基站通过去蜂窝单元,实现无线资源的集中控制和协调,这种集中控制和协调可以称为控制面的集中。
同时,去蜂窝单元的用户面数据包处理模块113,集中整个网络(比如基站自身控制的所有微基站)的数据处理功能,将业务数据集中地进行传输处理,增加对业务数据的细加工,即实现对业务数据的大数据计算,以减少数据的搬移,比如把基于PDCP/RLC协议的业务数据进行集中传输处理,从而实现业务数据的快速发送。而将除业务数据外的其它用户面数据,比如基于TCP/IP等处理的高层用户面数据的处理功能下移至相应的Cell_MAC单元,由Cell_MAC单元对除所述业务数据外的其它用户面数据进行传输处理,从而为用户提供更丰富的数据服务。
所述去蜂窝单元11利用所述获得的各小区资源,基于全局或者局部最优收敛算法,为所述UE分配相应的小区资源。换句话说,去蜂窝单元把海量小区的计算功能进行了集中,快速计算得到全局或者局部最优收敛结果,为用户提供最合适的无线资源(包括:物理资源块(PRB,Physical Resource Bulk)、功率等)服务;并在获得全局或局部(Cell级)最优收敛结果后,分散到Cell_MAC单元上,由相应的Cell_MAC单元再为所述UE分配相应的空口资源,从而实现空口资源的快速分配。因此,去蜂窝单元的计算能力可以认为是一种集中的计算能力。
另外,从链路的角度来看,如图5所示,用户链路分为集中的用户链路(图5中的
Figure PCTCN2016098804-appb-000001
所示的链路)和分散的用户链路(图5中的
Figure PCTCN2016098804-appb-000002
所示的链路);具体地,从Cell_MAC单元以上至核心网(CN)各单元模块之间的用户链路,是一种集中的用户链路,而Cell_MAC单元以下到空口采用分散的用户链路。其中,
集中的用户链路以传统的无线承载进行业务的传递,可以认为是一种半静态链路,该半静态链路只负责承载具体的业务。换句话说,当业务发生变化时,这个集中的用户链路会发生变化,业务不发生变化时,这个集中的用户链路不会发生变化,因此该用户链路可以称为是一种半静态链路。
分散的用户链路,根据用户在空口的信道状态和全网需求,实时动态地 选择合适的物理(PHY)信道把数据发送到空口,换句话说,分散的用户链路是一种动态链路。
集中和分散的用户链路基于集中的控制面、集中的用户面和集中的计算能力提供的控制、数据和计算结构,实现与空口实时性同步的实时性协作,根据5G网络各种场景选择合适的空口传输技术,从而突破传统网络架构的扁平化控制方式,实现了网络的“No More Cell”功能。
这里,需要说明的是:如图5所示,实际应用时,各Cell_MAC单元与控制面信令处理子模块、和集中调度子模块之间、以及去蜂窝单元的各模块之间存在相应的信令交互,以实现资源的分配以及数据的传输,如图5中的粗实线
Figure PCTCN2016098804-appb-000003
所示。
实际应用时,所述去蜂窝单元11、第一Cell_MAC单元12、控制面信令处理模块11_1、控制面信令处理子模块111、集中调度子模块112、以及用户面数据包处理模块113、第二Cell_MAC单元13可由基站中的中央处理器(CPU,Central Processing Unit)、微控制单元(MCU,Micro Control Unit)、数字信号处理器(DSP,Digital Signal Processor)或可编程逻辑阵列(FPGA,Field Programmable Gate Array)实现。
本公开实施例提供的基站,所述去蜂窝单元11利用所述基站1自身获得的各小区资源,为UE分配相应的小区资源;所述第一Cell_MAC单元12基于为所述UE分配的小区资源,在为所述UE分配的小区资源上,为所述UE分配业务对应的无线资源;所述基站1包含一个以上Cell_MAC单元;所述第一Cell_MAC单元12为与为所述UE分配的小区资源对应的Cell_MAC单元,如此,采用了资源集中控制和协调处理的方式,如此,能有效降低信令开销及信令处理时延,从而能有效地满足高实时性同步的实时性协作要求,提升用户体验。
另外,进行业务过程中,所述去蜂窝单元11将来自核心网的业务数据进行传输处理;所述第一Cell_MAC单元12利用为所述UE分配的无线资源,将传输处理后的业务数据通过空口发送给所述UE,如此,能有效提高数据处理速度,进一步提升用户体验。
当所述UE由于位置移动而发生了小区切换时,所述控制面信令处理子 模块111利用获得的各小区资源,基于全局或者局部最优收敛算法,重新为所述UE分配相应的小区簇资源;所述集中调度子模块112基于全局或者局部最优收敛算法,并结合重新分配的小区簇资源,为所述UE重新分配相应的小区资源;所述第二Cell_MAC单元13利用基于所述UE的传输特性,在重新为所述UE分配的小区资源上,为所述UE分配业务对应的无线资源;并利用为所述UE分配的无线资源,将传输处理后的业务数据通过空口发送给所述UE;所述第二Cell_MAC单元13为与重新为所述UE分配的小区资源对应的Cell_MAC单元,如此,能进一步地有效降低信令开销及信令处理时延,进步一步有效地实现与空口实时性同步的实时性协作。
除此以外,由于本公开实施例的基站仅需要进行软件的改动,所以具有很好地扩展性,且能够快速支持海量用户。并且,还有很好地兼容性,能够很好地兼容3G、4G等网络。
在实施例中,基于本公开实施例的基站,本实施例提供一种资源分配方法,如图6所示,该方法包括以下步骤:
步骤601:基站的去蜂窝单元利用所述基站自身获得的各小区资源,为UE分配相应的小区资源;

所述去蜂窝单元的集中调度子模块基于全局或者局部最优收敛算法,并结合分配的小区簇资源,为所述UE分配相应的小区资源。
这里,实际应用时,所述控制面信令处理子模块以及集中调度子模块可以合设在一起,即形成控制面信令处理模块。此时,对于上述过程,则是:
所述去蜂窝单元的控制面信令处理模块利用获得的各小区资源,基于全局或者局部最优收敛算法,为所述UE分配相应的小区簇资源;并基于全局或者局部最优收敛算法,并结合分配的小区簇资源,为所述UE分配相应的小区资源。
实际应用时,所述基站可以通过UE上报的方式、或者与其它基站交互 的方式,获得各小区资源。
其中,实际应用时,针对5G网络的应用场景,本实施例的方案可以应用于宏基站+微基站的应用场景,相应地,此时,所述基站获得的各小区资源为自身控制下的微基站对应的各小区资源。
步骤602:基站的第一Cell_MAC单元基于为所述UE分配的小区资源,在为所述UE分配的小区资源上,为所述UE分配业务对应的无线资源。

当所述UE需要进行业务时,所述去蜂窝单元利用所述基站自身获得的各小区资源,为UE分配相应的小区资源;相应地,第一Cell_MAC单元基于所述UE的传输特性,在为所述UE分配的小区资源上,为所述UE分配业务对应的无线资源,以便后续利用分配的无线资源进行业务数据的传输。
其中,由于要实现所述去蜂窝单元的功能,就要求去蜂窝单元具有基于大数据云计算的能力。
分配的小区资源包括小区的功率、标识、信道等。
由于控制面信令处理子模块利用获得的各小区资源,基于全局或者局部最优收敛算法,为所述UE分配相应的小区簇资源,要利用所有小区资源来分配相应的小区簇资源,数据量是海量的,所以该过程的处理速度比较慢(比如RRC过程),而所述集中调度子模块是结合分配的小区簇资源,为所述UE分配相应的小区资源,数据量是比较少的,所以该过程的处理速度比较快。

这里,所述传输处理是指:实现将核心网下发的用户面数据发送至所述UE所需要的各种处理,比如:压缩、加密等等。
所述业务数据可以是基于PDCP/RLC协议处理的用户面数据等;所述其它用户面数据可以是基于TCP/IP处理的高层用户面数据等。
在实施例中,进行业务数据传输时,该方法还可以包括:

相应地,所述集中调度子模块基于全局或者局部最优收敛算法,并结合重新分配的小区簇资源,为所述UE重新分配相应的小区资源;
所述第二Cell_MAC单元利用基于所述UE的传输特性,在重新为所述UE分配的小区资源上,为所述UE分配业务对应的无线资源;并利用为所述UE分配的无线资源,将传输处理后的业务数据通过空口发送给所述UE;所述第二Cell_MAC单元为与重新为所述UE分配的小区资源对应的Cell_MAC单元。
需要说明的是:在上述实施例中,当所述控制面信令处理子模块和集中调度子模块合设在一起,形成所述控制面信令处理模块时,由所述控制面信令处理模块执行所述控制面信令处理子模块和集中调度子模块的功能。具体 包括:

进行业务数据传输时,所述去蜂窝单元的用户面数据包处理模块基于所述控制面信令处理模块的资源分配结果,将来自核心网的业务数据进行传输处理;
相应地,所述控制面信令处理模块基于全局或者局部最优收敛算法,并结合所述用户面数据包处理模块的处理结果及分配的小区簇资源,为所述UE分配相应的小区资源,并将传输处理后的业务数据发送至所述第一Cell_MAC单元;

所述业务进行过程中,当所述UE发生小区切换时,所述控制面信令处理模块利用获得的各小区资源,基于全局或者局部最优收敛算法,重新为所述UE分配相应的小区簇资源;并基于全局或者局部最优收敛算法,并结合重新分配的小区簇资源,为所述UE重新分配相应的小区资源;
所述第二Cell_MAC单元利用基于所述UE的传输特性,在重新为所述UE分配的小区资源上,为所述UE分配业务对应的无线资源;并利用为所述UE分配的无线资源,将传输处理后的业务数据通过空口发送给所述UE;所述第二Cell_MAC单元为与重新为所述UE分配的小区资源对应的Cell_MAC单元。
