Description

一种资源分配方法及装置 技术领域
本发明涉及移动通信技术领域,尤其涉及一种资源分配方法及装置。
背景技术
日益增长的用户容量需求与有限的频谱资源是目前移动通信网络建设的主要问题之一。目前,各运营商的授权频带资源有限,可提供的容量也有限,尤其当移动通信网络从2G、3G发展至4G后,用户的吞吐量显著提高,容量需求呈指数倍增长,更突显出了有限频谱资源与不断增长的用户容量需求间的矛盾。另外,目前尚处于研究阶段的5G技术,提出了更高的吞吐量要求,对网络资源的需求更大,使用更苛刻。
在传统移动通信网络中采用的扩容以提高网络容量的手段已经不适宜现有的移动通信网络的发展,采用扩容可在一定程度上增加网络的容量,但是由于基站性能、频带资源的制约,扩容可达到的容量效果有限。目前,各运营商及移动通信设备厂家针对用户容量的井喷式增加,主要是考虑提高资源的利用率,现有两个主要的研究方向:1)扩展频带,较多地将目光放到了5G的非授权频段,利用非授权频带充足的带宽资源来补充授权频带,为用户带来更高的吞吐量体验,诸如LTE-U、LAA技术等;2)资源复用,提高资源的复用程度达到提高资源利用率的目的,诸如MU-MIMO,同频组网,以及5G内提出的小区虚拟化。
小区虚拟化技术是5G提出的一个全新概念,其打破现有移动通信网络中基站与小区之间的固定关系,采用虚拟小区作为基本的小区单元,该虚拟小区与基站没有任何指定关系。引入小区虚拟化技术,通过虚拟小区划分和集中式资源管理分配,达到资源复用的目的。现有的小区虚拟化技术主要涉及以下方面:1)以用户为中心的小区虚拟化,围绕每个用户生成一个小区簇,小区簇内有多个小区,通过多点协作、天线技术等使得一个小区可在多个小区簇内,从而实 现小区资源的复用。该技术目前尚需借助多点协作、天线技术来将同一小区的资源用于不同的用户。2)小区分裂。将物理小区的资源视为一个整体集中式管理,统一进行资源分配,并通过小区分裂技术形成多个虚拟小区,各虚拟小区均可使用集中式管理的物理小区资源,实现资源复用,资源的复用程度由虚拟小区的分裂数目决定。该技术可涉及多个物理小区,如共小区技术;也可涉及单个物理小区,如OneCell技术。该技术采用集中式的资源管理分配,可根据覆盖区域内用户的业务需求变化来分配资源,充分使用已有资源来提高资源的利用率,且可减少用户流动过程中的信令交互,减少系统资源的占用。相比之下,小区分裂技术的实现更为简单,且能实现资源较高程度的复用,可显著提高吞吐量,在小区分裂中对单个小区执行小区分裂,资源的复用程度更高,网络容量的提升效果更明显。
目前对单个小区的小区分裂技术,较多地研究应用在近端+远端的基站架构上,利用基站远端设备间的隔离来实现资源复用,小区分裂的程度受限于近端与远端间的交互接口。现有主要研究如何最大程度地划分虚拟小区实现资源复用,并没有考虑用户业务情况,也没有考虑对实际用户期望达到的资源复用效果。

图1示意性示出了本发明一个实施例的一种资源分配方法的流程图。参照图1,本发明实施例提供的资源分配方法具体包括以下步骤:
S101、根据物理小区内用户的业务信息,将所述物理小区划分为一个以上的虚拟小区。
本发明实施例针对的情形为同一物理小区的虚拟小区的划分,具体的,所述网络侧设备在物理小区与用户间设置虚拟层,所述虚拟层为虚拟资源所在的层,所述网络侧设备在所述虚拟层为用户进行虚拟资源分配,其中,物理小区、用户和虚拟层三者的关系如图2所示。
本实施例中,网络侧设备根据用户业务分布信息将虚拟层划分为多个不重叠的区域,每个区域标记为一个虚拟小区。所述网络侧设备的初始虚拟小区划分,是根据用户初始业务分布信息,将满足一定条件的一片连续覆盖区域划分为一个虚拟小区,所述虚拟小区的覆盖区域互不重叠。参见图2,所述虚拟层被划分为了虚拟小区1~虚拟小区5共5个虚拟小区,这5个虚拟小区的覆盖区域互不重叠。
其中,用户业务分布信息包括但不限于用户数目、用户的位置、用户的业务类型、用户的物理资源需求和用户的虚拟资源需求等信息。在本发明的一个具体的实施例中,所述用户的虚拟资源需求,为根据用户业务需求所需为用户分配的最小虚拟资源数目。
具体的,所述根据用户业务分布信息对所述虚拟层进行虚拟小区划分包括:
根据所述物理小区内用户的业务信息,将满足第一预设条件的所述物理小区中的一个连续覆盖区域划分为一个虚拟小区。
所述预设条件至少包括下述条件之一:所述连续覆盖区域内的用户数量达到第一预设阈值,或,所述连续覆盖区域内用户的虚拟资源需求总量达到第二 预设阀值。
可理解的,所述第一预设阈值和第二预设阀值可根据实际应用场景进行具体设定,对此本发明实施例不做具体限定。
S102、建立所述物理小区的物理资源与每个虚拟小区的虚拟资源之间的映射关系。其中,所述虚拟资源为虚拟小区可分配的资源,每个虚拟小区对应有一个虚拟资源。
在本发明实施例中,步骤S103具体通过以下步骤实现:

将所述各虚拟小区对应用户的虚拟资源需求总量分别与预设的第一资源门限和预设的第二资源门限进行比较,其中,所述预设的第一资源门限大于所述预设的第二资源门限;
当虚拟资源需求总量大于所述第一资源门限的第一类虚拟小区的数量大于预设的第一调整门限值时,对所述第一类虚拟小区进行小区分裂,所述第一类虚拟小区为虚拟资源需求总量大于所述第一资源门限的虚拟小区;
当虚拟资源需求总量小于所述第二资源门限的第二类虚拟小区的数量大于预设的第二调整门限值时,对所述第二类虚拟小区进行小区合并,所述第二类虚拟小区为虚拟资源需求总量小于所述第二资源门限的第二类虚拟小区。
当所述第一类虚拟小区的数量大于零,且小于或等于所述预设的第一调整门限值时,所述方法还包括:
依次获取所述第一类虚拟小区中边缘用户的虚拟资源需求;
当所述边缘用户的虚拟资源需求小于或等于与所述边缘用户所在虚拟小区相邻的虚拟小区的资源需求余量时,将所述边缘用户划分至所述相邻的虚拟小区,并更新所述相邻的虚拟小区的资源需求余量,所述资源需求余量为所述第一资源门限减所述相邻的虚拟小区当前用户的虚拟资源需求总量后剩余的虚拟资源量,在本发明的实施例中,并不仅仅限于与所述边缘用户所在虚拟小区相邻的虚拟小区,在所述边缘用户所在虚拟小区周围的虚拟小区都可以实现上述步骤;
当所述第一类虚拟小区相对所述预设的第一资源门限超出的资源需求量小于或等于零时,停止获取当前第一类虚拟小区中边缘用户的虚拟资源需求,并相应的调整所述虚拟小区的数量。
