本申请涉及无线通信技术领域,尤其涉及一种多制式网络控制方法以及网管设备。
无线通信系统的能耗支出在网络运营成本中的占比较高,尤其是在当前全球移动通讯系统(global system for mobile communication,GSM)、通用移动通信系统(universal mobile telecommunications system,UMTS)、长期演进(long term evolution,LTE)网络等多种制式网络并存的情况下,如何更经济地利用不同网络提供服务,减少运营成本,已成为是业界关注的热点。
现有技术中,针对不同制式网络制定相应的节能策略,当相应制式网络满足关断条件时,关断该制式网络的小区,进而达到节能的目的。但是,随着GUL频谱重整(refarming),多制式网络射频共模的比例不断提升,而现有的不同制式网络的节能策略之间是相互独立的,导致现有的节能策略难以生效,节能效果不明显。例如,当GSM网络的1800MHz频段G1800与LTE网络的1800MHz频段L1800共射频(radio frequency,RF)模块时,若G1800不满足相应的关断条件,即使L1800满足相应的关断条件也不能关断。

具体地,在步骤S201中,所述网管设备获取所述网管设备管理的基站的配置文件,从所述配置文件中获取所述基站的工程参数以及所述基站的配置参数。由于现有通信网络中存在分离主控站点(物理基站),在此类站点中不同的逻辑基站配置文件也相互独立,但不同逻辑基站中的小区可能会共用射频(radio frequency,RF)模块。因此,需要针对逻辑基站中的小区共用射频模块的场景进行识别,建立起站点与逻辑基站间的关系,进而建立逻辑小区与射频模块的映射关系,从而使得所述网管设备能够从获得的基站的配置文件中,确定每个逻辑小区对应的实际基站。
具体实施中,所述网管设备从获得的基站配置文件中识别基站的名称、基站的标识、 基站各小区的标识,以及小区对应的射频模块的柜框槽号,建立不同制式网络小区与射频模块的柜框槽号的映射关系,以判断不同制式网络小区是否物理共站以及共RF模块,进而获得较好的节能效果。

4、从基站配置文件获取射频模块柜框槽号:a、对于ANTCFGMODE(天线配置方式)为ANTENNAPORT(天线端口)的配置方式,从基站配置文件<SECTOREQM>(扇区设备)元素中读取各扇区设备(SECTOREQMID)发射天线端口(ANTTYPE等于2或3)对应的RF模块柜框槽号;b、对于ANTCFGMODE(天线配置方式)为BEAM(波束)的配置方式,RRUCN(RRU柜号)、RRUSRN(RRU框号)、RRUSN(RRU槽号)分别表示RF模块对应的柜框槽号;
5、根据获取到的基站信息、小区信息以及RF模块对应的柜框槽号,建立LTE网络小区与RF模块的映射关系。

对于4G网络(如LTE网络),所述网管设备还可以通过基站配置文件,确定小区是否支持语音业务(VoLTE业务),可以用参数“Support VoLTE”表示。具体地,所述网管设备通过查看命令eNodeB级算法开关ENODEBALGOSWITCH,查看eNodeB级算法开关中的参数EUTRAN支持VoIP能力开关EutranVoipSupportSwitch,如果设置为“ON”,则该eNodeB下所有LTE小区均支持Volte业务。

一个具体的实施方式中,由于宏小区相对于室内小区功耗较大,为了进一步提高节能效果,所述网管设备确定的第二类频段对应的小区为宏小区。
一个具体的实施方式中,当所述第二类频段对应的小区中存在多远程射频单元RRU共小区时,所述第一类频段对应的小区中存在多RRU共小区,以保证网络覆盖一致,进而保证所述第二类频段关断后的网络性能。
一个具体的实施方式中,当所述基站支持的多种网络制式包括2G网络、3G网络以及4G网络时,所述基站支持的2G网络对应的第一类频段以及第二类频段满足以下条件中的任意一种:
a、所述基站支持的2G网络对应的第一类频段的频率低于所述第二类频段的频率,所述基站支持的2G网络对应的第二类频段中不存在4G网络的电路域回落的频点或邻小区;或者,
b、所述基站支持的2G网络对应的第一类频段的频率低于所述基站支持的2G网 络对应的第二类频段的频率,且所述基站支持的2G网络对应的第一类频段中存在4G网络的电路域回落的频点或邻小区;或者,
c、所述基站支持的2G网络对应的第一类频段的频率低于所述基站支持的2G网络对应的第二类频段的频率,所述基站支持的2G网络对应的第一类频段中不存在4G网络的电路域回落的频点或邻小区,所述基站支持的2G网络对应的第二类频段中不存在4G网络的电路域回落的频点或邻小区,但所述基站支持的3G网络对应的第一类频段中存在4G网络的电路域回落的频段的频点或邻小区。
例如,对于所述基站支持的GSM网络,GMS网络包括1800MHz频段G1800和900MHz频段G900,所述GSM网络对应的第一类频段为G900,所述GSM网络对应的第二类频段为G1800,其中,G1800中不存在4G网络的CSFB的频点或邻小区;或者,所述GSM网络对应的第一类频段为G900,所述GSM网络对应的第二类频段为G1800,其中,G900中存在4G网络的CSFB的频点或邻小区;或者,所述GSM网络对应的第一类频段为G900,所述GSM网络对应的第二类频段为G1800,其中,G900以及G1800中均不存在4G网络的CSFB的频点或邻小区,所述基站支持的UMTS网络对应的第一类频段中存在4G网络的CSFB的频点或邻小区。
也就是说,以下任意一种场景下所述基站支持的GSM网络不能够关断:i、G1800对应的小区中存在4G网络的CSFB的频点或邻小区,即G1800对应的小区“CSFB Target”不为NULL,且同站(地理同站或共RF模块)G900对应的小区“CSFB Target”为NULL,且同站的UMTS网络对应的小区中不存在4G网络的CSFB的频点或邻小区,“CSFB Target”为NULL;ii.G1800对应的小区为非宏小区;iii、不存在G1800。

进一步地,当所述基站支持的多种网络制式包括2G网络、3G网络以及4G网络时,若所述基站支持的4G网络不支持语音通话业务,所述基站支持的3G网络支持4G网络的电路域回落,则所述基站支持的3G网络对应的第一类频段中存在4G网络的电路域回落的频点或邻小区;或者,所述基站支持的2G网络对应的第一类频段中存在4G网络的电路域回落的频点或邻小区。
例如,对于所述基站支持的UMTS网络,UMTS网络包括900MHz频段U900和2100MHz频段U2100。所述网管设备根据所述基站支持的UMTS网络的工程参数以及配置参数,分别将U900以及U2100中小区个数最多的频点确定为所述基站支持的UMTS网络对应的第一类频段,如果U2100对应的小区中支持U900的终端设备的比例不足90%,则U2100不能作为所述基站支持的UMTS网络对应的第二类频段,将U900以及U2100中除所述基站支持的UMTS网络对应的第一类频段外的其他频点确定为所述基站支持的UMTS网络对应的第二类频段,即所述基站支持的UMTS网络对应的工作频段只可以做频段内的载波关断。
如果U900或者U2100不存在,则将U900以及U2100中除所述基站支持的UMTS网络对应的第一类频段外的其他频点确定为所述基站支持的UMTS网络对应的第二类频段,即所述基站支持的UMTS网络对应的工作频段只可以做频段内的载波关断;如果U900或者U2100不存在,且频段内只有1个频点,则所述基站支持的UMTS网络 无法进行节能优化。
进一步地,当U900中存在U2100的共覆盖小区时,如果所述网管设备根据所述基站支持的UMTS网络的工程参数以及配置参数,确定同站(地理共站/共RF模块)LTE小区不支持Volte,且同站UMTS小区的参数“CSFB Target”不全为NULL,说明所述基站支持的UMTS网络支持从LTE网络到UMTS网络(L2U)的CSFB,此时U900或U2100中的第一类频段对应的小区的参数“CSFB Target”必须非NULL,即所述U900或U2100中的第一类频段对应的小区支持L2U CSFB,U2100整个频段才能作为所述基站支持的UMTS对应的第二类频段,否则,同站存在不被关断的GSM小区的参数“CSFB Target”必须非NULL(比如G900,或者存在不参与关断的G1800),即所述基站所支持的GSM网络对应的第一类频段中存在L2U CSFB的频点或邻小区,否则将U900对应的第一类频段替换为同频段的小区个数次多的频点。如果逐个替换后所述U900中的第一类频段对应的小区依然不能支持L2U CSFB,则所述基站支持的UMTS网络对应的工作频段只可以做频段内的载波关断。
当U900中不存在U2100的共覆盖小区时,如果所述网管设备根据所述基站支持的UMTS网络的工程参数以及配置参数,确定同站(地理共站/共RF模块)LTE小区不支持Volte,且同站UMTS小区“CSFB Target”不全为NULL,说明所述基站支持的UMTS网络支持从LTE网络到UMTS网络(L2U)的CSFB,此时U900或U2100中的第一类频段对应的小区“CSFB Target”必须非NULL,即所述U900或U2100中的第一类频段对应的小区支持L2U CSFB,U2100整个频段才能作为所述基站支持的UMTS对应的第二类频段,否则,同站存在不被关断的GSM小区“CSFB Target”必须非NULL(比如G900,或者存在不参与关断的G1800),即所述基站所支持的GSM网络对应的第一类频段中存在L2U CSFB的频点或邻小区,否则将U900对应的第一类频段替换为同频段的小区个数次多的频点。如果逐个替换后所述U900中的第一类频段对应的小区依然不能支持L2U CSFB,则保留原有U900对应的第一类频段,将U2100对应的第一类频段替换为同频段的小区个数次多的频点,直到替换后所述U2100中的第一类频段对应的小区支持L2U CSFB。
其中,所述基站支持的UMTS网络对应第二类频段的关断优先级为高频点的优先级大于低频点的优先级。
一个可能的实施方式中,若所述基站支持的4G网络对应的工作频段为第一频段和第二频段,所述第一频段对应的频率小于1GHz,所述第二频段的频率大于所述第一频段的频率,则所述第一频段为所述基站支持的4G网络对应的第一类频段,所述第二频段为所述基站支持的4G网络对应的第二类频段。
