Description

一种室内分布式天线系统的资源管理方法、装置及系统 技术领域
本申请涉及无线通信领域的技术领域，尤其涉及一种室内分布式天线系统的资源管理方法、装置及系统。
背景技术
随着智能终端越来越普及，对无线数据业务的需求也呈爆发式的增长。据统计，约有60％的语音业务和90％的数据业务是发生在室内。因此，对于运营商而言，能够提供良好的室内覆盖是避免客户流失，提高企业效益的重要手段。由于建筑物自身的屏蔽和吸收作用，造成了无线电波较大的传输衰耗，形成了移动信号的弱场强区甚至盲区，并且建筑物诸如大型体育场馆、会展中心，大型购物商场、会议中心，由于智能终端使用密度过大，局部网络容量不能满足用户需求，无线信道发生拥塞现象。室内覆盖技术为上述问题提供了较佳的解决方案。其原理是利用室内分布式天线系统(Distributed Antenna System，简称DAS)将移动基站的信号均匀分布在室内每个角落，从而保证室内区域拥有理想的信号覆盖。
然而，相关的室内分布式天线系统解决方案存在3个重要缺陷，现在以基带处理单元(Building Base band Unit，简称BBU)+2通道射频拉远模块(Remote Radio Unit，简称RRU)和功分器(也可以使用耦合器)构建的DAS系统为例说明。
(1)1台RRU能承载的用户量和数据流量是有限的，可能导致在多用户的情况出现拥塞或者下载流量低。
(2)每个天线上的资源是均匀分布的，无法针对某一个天线的资源进行灵活的配置及动态的调整：比如天线1覆盖的区域业务量非常大，天线2覆盖的区域业务量少，天线3覆盖的区域没有业务，无法单独的动态调整资源(比如：载波资源分配、RB(Resource Block)资源块分配)，导致出现天线1业务拥塞、天线3闲置。
(3)无法实时根据用户量和业务量来实现自动功率控制，实现节能的目 的，比如发现某个或者某些天线覆盖的区域没有业务量或者信号和干扰的比值大时的情况下，可以适当降低发射功率或者关闭某些资源(比如，TDD(Time Division Duplex)时分复用的通讯系统，可以关闭某几个时隙；甚至关闭整个天线资源)来实现节能的目的。

本发明的实施方式
下文中将结合附图对本发明的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
本发明的实施例提供了一种室内分布式天线系统的资源管理方法、装置及系统，解决了相关的室内分布式天线系统中单一RRU网络容量低，且网络资源不能灵活配置的问题。
如图1所示，本发明实施例的一种室内分布式天线系统的资源管理方法，应用于基带处理模块，包括步骤11-12：
步骤11：根据室内网络覆盖量的需求，配置多个射频收发通道。
在本发明实施例中，一个基带处理模块可配置多个射频模块，每个射频模块又可配置多个射频收发通道，如图2所示，假定一个基带处理模块配置4个射频模块，每个射频模块有16个收发通道(用ANT1至ANT16表示)，则灵活实现1个至64个收发通道使用场景。当然，本发明实施例中也可配置更多的射频模块以支持大于64个通道的使用场景。与传统的DAS系统相比，本发明实施例中射频模块的数量可以灵活的配置，网络容量大幅提升。
步骤12：根据预定资源分配规则，将基带资源分配给多个所述射频收发通道，并指示多个所述射频收发通道将所述基带资源转换为射频资源发送给用户。
这里，该预定资源分配规则包括：根据每个射频收发通道所连接天线覆盖区域的业务量进行分配。根据预定资源分配规则将基带资源分配给所述射频收发通道，可以是根据每个射频收发通道所连接天线覆盖区域的业务量，将基带资源分配给多个所述射频收发通道。如某一射频收发通道所连接天线覆盖区域的业务量大，则为该射频收发通道多分配一些资源，或从天线覆盖区域业务量少的射频收发通道中调整一些资源分配给该射频收发通道，从而 实现网络资源的灵活配置。
本发明实施例的室内分布式天线系统的资源管理系统，根据预定资源分配规则将基带资源分配给多个射频收发通道，大大提升了网络容量，并实现多个射频收发通道资源的灵活配置，使网络优化更灵活和便捷。
可选地，上述步骤11，即根据室内网络覆盖量的需求，配置多个射频收发通道包括步骤111-112：
步骤111、根据室内网络覆盖量的需求，配置一个或多个射频模块。
步骤112、为每个所述射频模块配置多个射频收发通道。
在本发明实施例中，射频模块可以灵活的配置，下面以4个射频模块为例说明：
1个基带模块配置4个射频模块；每个射频模块有16个收发通道(图3中使用TRX来标示)，1个收发通道的输出端口可以通过射频线缆连接1个天线；1台设备最多支持64个天线。
本发明实施例不局限于1个收发通道仅仅连接1个天线，比如有些室内覆盖用户变化不大，不要求独立配置时，可以采用1个收发通道连接多个天线(通过功分器或者耦合器实现)。
如图3所示，根据室内覆盖面积、室内结构和可能的用户量，估算出需要天线的数目，比如n个，从而来确定需要配置的射频模块(按照每个射频模块支持16个收发通道，并且1个收发通道只连接1个天线的典型配置场景来计算)的数量：
(n/16得到的整数)+1就是需要的射频模块的数量：比如需要支持85个天线覆盖，85/16＝5.3125，则需要6个射频模块。未连接天线的收发通道输出端口可以接小负载，作为备用端口，后续如果有新的硬件布置天线的需要可以使用该备用端口。
与传统的DAS系统相比，本发明实施例的射频模块数量可以灵活的配置，网络容量大幅提升。另外，本发明实施例配置省去功分器或者耦合器(有能量损耗)，并且每个收发通道的衰减器是独立可调的，每个通道的基带资源是独立控制的，这样可以保证DAS系统中每个天线的功率和资源都是独立 配置的，从而能更好的覆盖室内用户移动或者解决覆盖不均匀分布的问题，比如大型的会展中心，每个展示区可能的参展人员数量不同、语音业务或者数据业务的数量也不同，每个天线承载的业务量差异非常大，本发明实施例可以很容易的通过调整各通道的资源分配来适应这种不均等的业务需求。
可选地，本发明实施例的室内分布式天线系统的资源管理方法，还包括：
根据与所述射频收发通道连接的天线所覆盖区域的业务量，对每个所述射频模块的射频收发通道的增益进行控制。
由于传统的DAS系统每个天线上发射信号的基带功率都是相同的，并且无法动态调整每个天线的功率(布线完成后，每个天线上的衰减就固定了)，本发明实施例可以通过基带处理模块调整每个天线的基带增益，并且每个射频模块的收发通道能实现增益的独立控制(独立的调整每个收发通道的衰减器)，可以实现业务量少，或者没有业务的天线独立降低发射功率来实现节能的目的。比如发现某个或者某些天线覆盖的区域没有业务量或者信号和干扰的比值大时的情况下，可以适当降低发射功率或者关闭某些资源(比如，时分复用的通讯系统(Time Division Duplex，TDD)，可以关闭某几个时隙；甚至关闭整个天线资源)来实现节能的目的。
可选地，本发明实施例的室内分布式天线系统的资源管理方法，还包括：
根据与所述射频收发通道连接的天线所覆盖区域的业务量，对每个所述射频收发通道的基带资源进行动态调整。
在本发明实施例中，可对每个所述射频收发通道的基带资源进行动态调整，解决有的天线下用户数据多而拥塞、有的天线下用户少而闲置的问题。另外，传统的DAS系统每个天线上发送数据相同，这样相邻天线间的用户更容易受到干扰，本发明实施例通过基带处理模块配置资源，可以实现每个天线上的数据都不相同，抗干扰能力更强，因此可以提升网络容量，同时该特性也使使用更高级的空分复用技术成为可能，便于后续网络能力进一步优化。
如图4所示，本发明实施例还提供了一种室内分布式天线系统的资源管理装置，包括：配置模块41和分配模块42。
配置模块41，设置为根据室内网络覆盖量的需求，配置多个射频收发通 道。
分配模块42，设置为根据预定资源分配规则，将基带资源分配给所述射频收发通道，并指示多个所述射频收发通道将所述基带资源转换为射频资源发送给用户。
本发明实施例的室内分布式天线系统的资源管理装置，所述配置模块41包括：第一配置子模块411和第二配置子模块412。
所述配置模块根据室内网络覆盖量的需求，配置多个射频收发通道包括：
第一配置子模块411，设置为根据室内网络覆盖量的需求，配置至少一个射频模块；
第二配置子模块412，设置为为所述射频模块配置多个射频收发通道。
本发明实施例的室内分布式天线系统的资源管理装置还包括：第一控制模块。
