Description

一种小区接入方法和设备
本申请要求在2014年03月13日提交中国专利局、申请号为201410093056.6、发明名称为“一种小区接入方法和设备”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明涉及无线通信技术领域,尤其涉及一种基于上下行信号覆盖不一致的小区接入方法和设备。
背景技术
随着通信技术的发展,为了实现通信系统的全面覆盖,部署的基站设备数量也越来越多。有些基站设备被部署在室内,有些基站设备被部署在热点区域,还有些基站设备被部署在高山上,也有些基站设备被部署在水边等等。
由于被部署在水边的基站设备发射以及接收到的信号受到大气、水表面反射的影响,形成了较强的反射径,而这些反射径与基站设备的直射路径叠加时,形成很强的信号(以后称这种信号为叠加信号),使得距离该基站设备较远的终端设备也能够接收到这种叠加信号,但是,受到终端设备发射功率等原因的影响,终端设备对接收到这种叠加信号的上行反馈信号无法到达该基站设备,出现基站设备的上下行信号不一致的情形。这种现象被称为湖边效应现象。
“湖边效应现象”产生的问题在于:当距离基站设备较远的终端设备受到“湖边效应现象”的影响而接入该基站设备时,终端设备的上行反馈信号不能到达该基站设备,使得终端设备随机接入该基站设备失败。
目前,为了解决基站设备的上下行信号不一致的情形,配置小区级别的小区重选偏移量。即对于受到“湖边效应现象”影响的基站设备A和与基站设备A距离较近且未受到“湖边效应现象”影响的基站设备B,为基站设备A配置小区重选偏移量,使得因为“湖边效应现象”注入的终端设备重选基站设备B,这样,导致本身基站设备A覆盖范围内的终端设备也将重选注入基站设备B,接入基站设备B的终端设备在通信过程中将受到基站设备A的干扰,使得通信质量下降。
综上所述,亟需一种小区接入方法,用于解决终端设备在“湖边效应现象”的影响下接入基站设备失败的问题,或者接入基站设备之后通信质量差的问题。

下面结合说明书附图对本发明的各个实施例进行详细描述。
实施例一:
如图1所示,为本发明实施例一提供的一种小区接入的方法的流程示意图。所述方法可以如下所述。
步骤101:终端设备接收驻留的服务小区发送的系统信息。
其中,所述系统信息中包含了小区驻留风险标识和测量信息。
在步骤101中,终端设备在接收到服务小区发送的参考信息时,选择参考信息对应的服务小区驻留。
终端设备在选择服务小区驻留的过程中,接收到参考信息中包含了受到湖边效应影响而加大反射路径的参考信息。
其中,受到湖边效应影响而加大反射路径的参考信息是由存在湖边效应风险的服务小区发送的。
当终端设备驻留的服务小区属于存在湖边风险的基站设备时,接收该驻入的基站设备发送的系统信息,其中,所述系统信息中包含了小区驻留风险标识和测量信息。
服务小区是否属于湖边效应风险服务小区的确定方法包括但不限于以下方式:
第一种方式:
首先,网络侧接收终端设备发送的接入小区失败事件信息。
其中,所述接入小区失败事件信息中包含了所述终端设备接入小区的标识信息以及所述终端设备当前所在的位置信息。
具体地,当终端设备驻留服务小区之后,请求接入该服务小区失败时,向网络侧发送接入小区失败事件信息,并通过接入小区失败事件信息告知网络侧发生接入失败小区的标识信息以及终端设备当前所在的位置信息。
其次,所述网络侧根据接收到的所述终端设备接入小区的标识信息,确定所述接入小区的位置信息。
需要说明的是,所述位置信息可以是经纬度信息以及高度信息,还可以是其他能够表示位置的信息,这里不做限定。
再次,所述网络侧在确定的所述位置信息与所述终端设备当前所在的位置信息之间的距离值大于设定第一阈值时,确定所述终端设备的接入小区发生了湖边效应。
具体地,所述网络侧计算确定的所述位置信息与所述终端设备当前所在的位置信息之间的距离值,当计算得到的距离值大于设定第一阈值时,说明终端设备在服务小区的信号覆盖范围之外,该终端设备能够接收到该服务小区发送的参考信息并驻留该服务小区,可能是受到湖边效应影响,因此,确定所述终端设备的接入小区发生了湖边效应。
最后,所述网络侧向确定发生湖边效应的服务小区发送小区驻留风险标识。
这样,标注该服务小区属于湖边效应易发生服务小区。
需要说明的是,第一阈值的取值可以取决于该服务小区的信号覆盖范围,还可以是根据实际测量得到的,也可以是根据实验数据得到的,这里不做限定。
第二种方式:
首先,网络侧接收终端设备发送的接入小区失败事件信息。
其中,所述接入小区失败事件信息中包含了所述终端设备接入小区的标识信息以及所述终端设备当前所在的位置信息。
具体地,当终端设备驻留服务小区之后,请求接入该服务小区失败时,向网络侧发送接入小区失败事件信息,并通过接入小区失败事件信息告知网络侧发生接入失败小区的标识信息以及终端设备当前所在的位置信息。
其次,所述网络侧根据所述终端设备当前所在的位置信息,确定所述位置信息上覆盖信号质量大于设定第二阈值的至少一个小区的标识信息。
具体地,所述网络侧根据所述终端设备当前所在的位置信息,确定所述位置信息上覆盖信号对应的小区的标识信息,并将确定的每一个小区的标识信息对应的小区在该位置上覆盖的信号质量进行测量,利用测量得到的每一个信号质量与设定的第二阈值进行比较, 得出信号质量大于设定第二阈值的小区的标识信息。
再次,在确定至少一个小区的标识信息对应的小区与所述终端设备接入小区的标识信息对应的小区不存在相邻关系时,确定所述终端设备的接入小区发生了湖边效应。
具体地,判断得出的信号质量大于设定第二阈值的小区与所述终端设备接入小区是否存在相邻关系,在确定至少一个小区的标识信息对应的小区与所述终端设备接入小区的标识信息对应的小区不存在相邻关系时,确定所述终端设备的接入小区发生了湖边效应。
需要说明的是,第二阈值可以是根据一个位置上信号覆盖质量确定的,还可以是根据实验数据确定,这里不做限定。
最后,向确定发生湖边效应的服务小区发送小区驻留风险标识。
需要说明的是,网络侧在确定一个服务小区是否属于容易发生湖边效应的服务小区可以采用上述方式对接收到的多个终端设备针对一个小区的接入失败事件信息进行分析确定的,还可以是通过其他方式,这里不做限定。
可选地,所述系统信息中还包含了所述服务小区预设的信号质量门限值。
步骤102:根据所述小区驻留风险标识,确定所述服务小区属于容易发生湖边效应的服务小区,并根据所述测量信息对所述服务小区的信号质量进行检测。
在步骤102中,由于容易发生湖边效应的服务小区发射的参考信号,除了一些距离较远的终端设备能够接收到参考信号之外,还存在一个距离较近的终端设备(即不受湖边效应的影响)也能够接收到该参考信号,那么对于不受湖边效应的影响的终端设备可以顺利接入该服务小区,因此,在终端设备接入服务小区之前,需要确定该终端设备接入该服务小区是否会受到湖边效应的影响。
此时,终端设备在接收到服务小区发送的测量信息和小区驻留风险标识时,根据所述小区驻留风险标识,确定所述服务小区处于容易发生湖边效应的服务小区,下一步需要对该服务小区的信号质量进行检测。
其中,所述测量信息中至少包含了小区频点信息、小区载波带宽等。
步骤103:利用检测得到的信号质量信息确定自身当前是否发生了湖边效应,若发生了湖边效应,则执行步骤104;否则,执行步骤105。
在步骤103中,所述终端设备将检测得到的信号质量信息与接收到的所述服务小区预设的信号质量门限值进行比较;并根据比较结果确定自身当前是否发生了湖边效应。
具体地,所述终端设备在确定监测得到的信号质量信息不大于接收到的所述服务小区预设的信号质量门限值时,确定自身当前尚未发生湖边效应;
所述终端设备在确定监测得到的信号质量信息大于接收到的所述服务小区预设的信号质量门限值时,确定当前发生了湖边效应。
需要说明的是,信号质量门限值可以是根据服务小区的信号在发生反射后确定的,还 可以是根据实验结果确定的,这里不做限定。
步骤104:在确定当前尚未发生湖边效应时,接入所述服务小区。
步骤105:所述终端设备在确定当前发生了湖边效应时,启动服务小区重选操作,并将所述服务小区设置为禁止自身接入的服务小区。
这样终端设备在接入服务小区之前对是否发生湖边效应进行判断,有效地使服务小区覆盖范围内的终端设备成功接入该服务小区,而使服务小区覆盖范围外因为湖边效应驻入的终端设备及时发现并禁止接入该服务小区,有效地避免了因为湖边效应导致终端设备接入失败的问题。
通过本发明实施例一的方案,终端设备接收驻留的服务小区发送的包含了小区驻留风险标识和测量信息的系统信息,根据所述小区驻留风险标识,确定所述服务小区属于容易发生湖边效应的服务小区,并根据所述测量信息对所述服务小区的信号质量进行检测;利用检测得到的信号质量信息确定所述终端设备当前是否发生了湖边效应,并在确定当前尚未发生湖边效应时,接入所述服务小区,这样终端设备在接入服务小区之前对是否发生湖边效应进行判断,有效地使服务小区覆盖范围内的终端设备成功接入该基站设备,而使服务小区覆盖范围外因为湖边效应驻留的终端设备及时发现并禁止接入该服务小区,有效地避免了因为湖边效应导致终端设备接入失败的问题,进而提高了终端设备的通信质量。

最后,所述网络侧向确定发生湖边效应的小区发送小区驻留风险标识。
这样,标注该服务小区属于湖边效应易发生服务小区。
需要说明的是,第一阈值的取值可以取决于该小区的信号覆盖范围,还可以是根据实际测量得到的,也可以是根据实验数据得到的,这里不做限定。
第二种方式:
首先,网络侧接收终端设备发送的接入小区失败事件信息。
