Description
本申请实施例涉及通信领域,尤其涉及一种小区频域带宽切换的方法、相关装置以及设备。
长期演进(long term evolution,LTE)***为了确保终端性能,每个传输时间间隔(Transmission Time Interval,TTI)都需要发送小区公共参考信号(cell-specific reference signal,CRS),而终端设备收到CRS后,可以将CRS用于时频偏跟踪、信道质量指示(Channel Quality Indication,CQI)测量、信道估计等。而CRS发送的频域带宽同主信息块(Master Information Block,MIB)中配置的小区带宽一致。因此,为了提高容量,在有用信号和噪声不变的情况下,需要提高频域带宽。更大的发射带宽提供了更大的容量,但网络负载较低时,不需要很大的带宽也可以满足容量诉求,此时大带宽提升了能耗。
目前,为了解决网络负载较低时,大带宽带来的能耗问题,可以将用户从当前频带切换到异频小区,然后重新配置原始小区带宽为较小带宽,再重新将用户切换回原始小区。
然而,由于需要一个单独的异频小区,当无异频小区覆盖时,无法利用异频小区进行带宽切换,其次,在去激活、重配小区、再激活小区强制切换成更小的带宽可能导致服务中断的问题,由此降低服务质量。
发明内容
本申请实施例提供了一种小区频域带宽切换的方法、相关装置以及设备,用于完成小区频域带宽切换,并且在频域带宽切换的过程中不会导致服务中断的问题,由此提升服务质量。
第一方面,本申请提供了一种小区频域带宽切换的方法。该方法可以由网络设备执行,或者也可以由配置于网络设备中的芯片执行,本申请对此不作限定。该方法包括:网络设备将终端设备从第一小区转移至第二小区,第二小区是基于第二频域带宽资源建立的,而第二频域带宽资源是在第一小区对应的第一频域带宽资源中确定的,然后网络设备基于第一小区建立第三小区,第三小区对应的第三频域带宽资源与第一频域带宽资源存在交集,交集为第一频域带宽资源以及第三频域带宽资源中具有相同频域带宽资源的集合,最后网络设备将终端设备从第二小区转移至第三小区。
在该实施方式中,由于第二频域带宽资源是在第一小区对应的第一频域带宽资源中确定的,因此将终端设备从第一小区转移至基于第二频域带宽资源建立的第二小区,不会导致服务中断的问题,其次,再将终端设备从第二小区转移至基于第一小区建立的第三小区,由于第一频域带宽资源以及第三频域带宽资源中具有相同频域带宽资源,但不完全相同,由此对终端设备而言,可以完成小区频域带宽切换,并且在频域带宽切换的过程中不会导致服务中断的问题,由此提升服务质量。
在本申请的一种可选实施方式中,当第一小区的小区负载小于第一阈值时,网络设备在第一频域带宽资源中确定第二频域带宽资源,且停止在第二频域带宽资源上调度终端设备,然后网络设备基于第二频域带宽资源建立第二小区,该第二小区禁止被小区外终端设备接入,小区外终端设备不属于第一小区对应的服务区域。或者,当第一小区的小区负载大于第二阈值时,网络设备在第一频域带宽资源中确定第二频域带宽资源,且停止在第二频域带宽资源上调度终端设备,然后网络设备基于第二频域带宽资源建立第二小区,该第二小区禁止被小区外终端设备接入,小区外终端设备不属于第一小区对应的服务区域。
在该实施方式中,当第一小区的小区负载小于第一阈值时,即不需要很大的带宽也可以满足容量诉求,因此可以将带宽减小,因此在第一频域带宽资源中确定第二频域带宽资源,此时第二频域带宽资源属于高带宽资源,并且在停止调度终端设备的第二频域带宽资源上建立第二小区,并且其他小区终端设备也无法接入第二小区,保证第二小区的第二频域带宽资源不被占用,由此提升本方案的可靠性。其次,当第一小区的小区负载大于第二阈值时,即当前带宽可能无法满足容量诉求,因此需要将带宽增大,因此在第一频域带宽资源中确定第二频域带宽资源,此时第二频域带宽资源属于较低带宽资源,并且在停止调度终端设备的第二频域带宽资源上建立第二小区,并且其他小区终端设备也无法接入第二小区,保证第二小区的第二频域带宽资源不被占用,进一步地提升本方案的可靠性。
在本申请的一种可选实施方式中,在网络设备将终端设备从第一小区转移至第二小区之前,网络设备还需要向终端设备发送第一消息,该第一消息指示终端设备对第二小区的信道资源进行异频测量,终端设备对第二小区的信道资源进行异频测量后得到第一异频测量结果,并且当第一异频测量结果大于或等于第三阈值时,网络设备会接收到终端设备发送的第一异频测量结果。具体地,第二小区的信道资源包括但不限于主信息块(Master Information Block,MIB),***信息块(System Information Blocks,SIB),物理下行控制信道(Physical Downlink Control Channel,PDCCH),物理下行共享信道(Physical Downlink Shared Channel,PDSCH)以及物理上行共享信道(Physical Uplink Shared Channel,PUSCH),具体第二小区的信道资源此处不做限定。
在该实施方式中,网络设备通过第一消息指示终端设备对新建的第二小区进行异频测量,通过异频测量后得到第一异频测量结果判断第二小区是否能够对终端设备提供正常的服务,在第一异频测量结果大于或等于第三阈值时,即第二小区能够对终端设备提供正常的服务,此时终端设备才会向网络设备发送第一异频测量结果,使得网络设备进行将终端设备从第一小区转移至第二小区的步骤,以保证在转移终端设备过程中服务不会中断,进一步地提升服务质量,并且提升本方案的可行性。
在本申请的一种可选实施方式中,在网络设备基于第一小区建立第三小区之后,且网络设备将终端设备从第二小区转移至第三小区之前,网络设备还会向终端设备发送第二消息,该第二消息指示终端设备对第三小区的信道资源进行异频测量,终端设备对第三小区的信道资源进行异频测量后得到第二异频测量结果,并且当第二异频测量结果大于或等于第四阈值时,网络设备会接收到终端设备发送的第二异频测量结果。具体地,第三小区的信道资源与第二小区的信道资源类似,包括但不限于MIB,SIB,PDCCH,PDSCH以及PUSCH,具体第三小区的信道资源此处不做限定。
在该实施方式中,网络设备通过第二消息指示终端设备对基于第一小区建立的第三小区进行异频测量,通过异频测量后得到第二异频测量结果判断第三小区是否能够对终端设备提供正常的服务,在第二异频测量结果大于或等于第四阈值时,即第三小区能够对终端设备提供正常的服务,此时终端设备才会向网络设备发送第二异频测量结果,使得网络设备进行将终端设备从第二小区转移至第三小区的步骤,以保证在转移终端设备过程中服务不会中断,进一步地提升服务质量,并且提升本方案的可行性。

在该实施方式中,由于第二频域带宽资源是在第一小区对应的第一频域带宽资源中确定的,因此终端设备从第一小区转移至基于第二频域带宽资源建立的第二小区,也能被提供服务,其次,再将终端设备从第二小区转移至基于第一小区建立的第三小区,由于第一频域带宽资源以及第三频域带宽资源中具有相同频域带宽资源,但不完全相同,因此终端设备完成小区频域带宽切换,并且没有导致服务中断,由此提升服务质量。
在本申请的一种可选实施方式中,在终端设备从第一小区转移至第二小区之前,终端设备还可以接收网络设备发送的第一消息,然后根据第一消息对第二小区的信道资源进行异频测量,得到第一异频测量结果,当第一异频测量结果大于或等于第三阈值时,终端设备向网络设备发送第一异频测量结果。具体地,第二小区的信道资源包括但不限于MIB,SIB,PDCCH,PDSCH以及PUSCH,具体第二小区的信道资源此处不做限定。

为了更好地理解本申请实施例公开的一种小区频域带宽切换的方法、相关装置以及设备,下面先对本发明实施例使用的通信***的***架构进行描述。请参阅图1,图1为本申请实施例中通信***的***架构示意图,如图1所示,该***可以包括一个或多个终端设备,分组核心网(Evolved Packet Core,EPC)以及演进型通用移动通信***陆地无线接入网(Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network,E-UTRAN)。具体地,E-UTRAN包括一个或多个eNB,还可以包括多播协调实体(Multicast Coordination Entity,MCE),并且多个eNB之间可以通过回程(backhaul)(例如X2接口)连接,例如eNB 1与eNB 2之间通过X2接口连接,eNB 1与eNB 3之间通过X2接口连接,以及eNB 2与eNB 3之间通过X2接口连接。而MCE可以为演进型多媒体广播/多播业务(Evolved Multimedia Broadcast/Multicast Services,eMBMS)分配时频无线资源,并且为eMBMS确定无线配置,MCE可以是独立于eNodeB的实体,也可以是eNodeB的一部分。其次,eNodeB提供终端设备到EPC的接入,因此eNodeB连接到EPC,EPC具体可以通过链路(例如S1接口)与eNodeB连接,而EPC可以包括但不限于移动性管理实体(Mobility Management Entity,MME),服务网关(Serving Gateway,S-GW)以及公用数据网网关(Public Data Network Gateway,P-GW),MME是处理UE和EPC之间信令的控制节点,提供承载和连接管理,而所有终端设备的网络协议(Internet Protocol,IP)包均通过S-GW进行发送,S-GW与P-GW进行连接,P-GW为终端设备提供IP地址分配以及其它功能。终端设备能够通过LTE网络和毫米波(millimeter wave,mmW)***进行信号通信,因此终端设备可以通过LTE链路和一个或者多个eNB进行通信,此外也可以通过mmW链路与其它连接点(connection point,CP)或基站进行通信。
在LTE***中,为了确保终端性能,由于每个TTI都需要发送CRS,而CRS发送的频域带宽同MIB中配置的小区带宽一致。因此,为了提高容量,在有用信号和噪声不变的情况下,需要提高频域带宽。更大的发射带宽提供了更大的容量,但网络负载较低时,不需要很大的带宽也可以满足容量诉求,此时大带宽提升了能耗。目前,为了解决网络负载较低时,大带宽带来的能耗问题,可以将用户从当前频带切换到异频小区,然后重新配置原始小区带宽为较小带宽,再重新将用户切换回原始小区。然而,由于需要一个单独的异频小区,当无异频小区覆盖时,无法利用异频小区进行带宽切换,其次,在去激活、重配小区、再激活小区强制切换成更小的带宽可能导致服务中断的问题,由此降低服务质量。
为了解决上述问题,本申请实施例提供了一种小区频域带宽切换的方法,用于完成小区频域带宽切换,并且在频域带宽切换的过程中不会导致服务中断的问题,由此提升服务质量。
下面对本申请实施例使用的小区频域带宽切换的方法进行详细描述,由于小区频域带宽切换需要小区A以及小区B的同时工作,因此终端设备需要对小区A以及小区B的信道资源进行异频测量,对小区A以及小区B的信道资源进行异频测量后得到的异频测量结果满足小区频域带宽切换条件的情况下,才能将终端设备从小区A切换到小区B,本申请实施例中仅使用原始小区的频域带宽资源,因此,为了满足小区频域带宽切换条件,本申请实施例需要在原始小区的频域带宽资源上发送小区A以及小区B的空口信号,为了尽量避免小区A以及小区B之间信号互相影响,采用频分的形式分别发送小区A以及小区B的信 号。对于频域带宽资源而言,需要在原始小区的频域带宽资源中确定小区A所使用的频域带宽资源,同时禁止原始小区中的终端设备接入小区A,在满足小区频域带宽切换条件后,将原始小区中的终端设备转移至小区A,完成切换后,基于原始小区的频域带宽资源建立频域带宽资源有交集但不完全相同的小区B,在满足小区频域带宽切换条件后,将小区A终端设备转移至小区B,通过这个过程,完成小区频域带宽切换,在频域带宽切换的过程中不会导致服务中断的问题,由此提升服务质量。
由于本申请实施例可以完成将小区频域带宽从大带宽切换至小带宽,也可以完成将小区频域带宽从小带宽切换至大带宽,下面分别对两种情况进行介绍。
一、大带宽切换至小带宽
为了便于理解,以第一小区对应的第一频域带宽资源为20兆(M),第二小区对应的第二频域带宽资源为5M,第三小区的对应的第三频域带宽资源为10M作为示例进行介绍,前述示例不应理解为本申请的限定。请参阅图2,图2为本申请实施例中小区频域带宽切换的方法一个实施例示意图,如图2所示,小区频域带宽切换的方法包括如下步骤。
S101、当第一小区的小区负载小于第一阈值时,则网络设备在第一频域带宽资源中确定第二频域带宽资源,且停止在第二频域带宽资源上调度终端设备。
本实施例中,由于第一小区对应的第一频域带宽资源为20M,当第一小区的小区负载小于第一阈值时,不需要很大的频域带宽也可以满足容量诉求,即20M的第一频域带宽资源并未被完全利用,因此可以通过减少频域带宽资源以达到节能的效果。由此,网络设备在第一频域带宽资源中确定第二频域带宽资源,此时第二频域带宽资源为高带宽资源,即网络设备闭塞20M中高端5M资源块(Resource Block,RB),并且停止在第二频域带宽资源上调度终端设备,即停止在闭塞的5M RB上调度终端设备。进一步地,网络设备还需要打孔第二频域带宽资源的CRS。
具体地,本实施例中第一阈值可以为60%或者50%等,具体第一阈值需要根据第一小区的具体第一频域带宽资以及第一小区的具体小区负载的实际情况灵活确定。
为了便于理解,请参阅图3,图3为本申请实施例中确定第二频域带宽资源一个实施例示意图,如图3所示,A1指示第一小区,A2指示第一频域带宽资源,A3指示第二频域带宽资源,在第一小区A1对应的第一频域带宽资源A2上闭塞第二频域带宽资源A3对应的RB,由此确定第二频域带宽资源A3,并且停止在第二频域带宽资源A2上调度终端设备,以及打孔第二频域带宽资源A3的CRS。可以理解的是,图3的示例仅用于理解本方案,不应理解为本申请的限定。
S102、网络设备基于第二频域带宽资源建立第二小区,其中,第二小区禁止被小区外终端设备接入,小区外终端设备不属于第一小区对应的服务区域。
本实施例中,网络设备在第二频域带宽资源的位置新建立一个独立的异频小区,该异频小区即为第二小区,并且禁止第二小区被小区外终端设备接入,即不允许不属于第一小区对应的服务区域外的终端设备接入。此时第二小区的第二频域带宽资源为高频率5M,即第二频域带宽资源的范围可以为15M至20M。
具体地,第二小区包括但不限于MIB,SIB,PDCCH,PDSCH以及PUSCH等信道资源,具体第二小区具体的信道资源此处不做限定。
进一步地,由于临近小区物理小区标识(Physical Cell Identification,PCI)MOD3相同,那么CRS发送的载波会产生同频干扰,为了避免第一小区与第二小区相互干扰,第二小区的PCI MOD3与第一小区需要错开,并且第一小区不在此5M频谱内调度,从而避免两个小区间相互干扰。
为了便于理解,请参阅图4,图4为本申请实施例中建立第二小区一个实施例示意图,如图4所示,B1指示第一频域带宽资源,B2指示第二频域带宽资源,B3指示第二小区,在第一频域带宽资源B1上通过步骤S101的方式确定第二频域带宽资源B2,并且停止在第二频域带宽资源B2调度终端设备,进一步地,基于第二频域带宽资源B2建立第二小区B3。可以理解的是,图4的示例仅用于理解本方案,不应理解为本申请的限定。
S103、网络设备向终端设备发送第一消息。
本实施例中,网络设备通过步骤S102建立第二小区之后,需要确定第二小区能够对终端设备提供正常的服务,因此终端和设备还需要对处于第一小区对应的服务区域中的所有终端设备发送第一消息,第一消息指示第一小区对应的服务区域中的所有终端设备对第二小区的信道资源进行异频测量。
S104、终端设备根据第一消息对第二小区的信道资源进行异频测量,得到第一异频测量结果。
本实施例中,终端设备接收到步骤S103中网络设备所发送的第一消息之后,由于第一消息指示第一小区对应的服务区域中的所有终端设备对第二小区的信道资源进行异频测量,因此终端设备对第二小区的信道资源进行异频测量,并得到第一异频测量结果。具体地,终端设备对第二小区的MIB,SIB,PDCCH,PDSCH以及PUSCH等信道资源进行异频测量,得到第一异频测量结果。
进一步地,终端设备得到第一异频测量结果之后,需要判断第二小区是否能够对终端设备提供正常的服务,由于第一异频测量结果可以指示第二小区的信道资源的信号强度,因此第一异频测量结果小于第三阈值时,即反映第二小区的信道资源的信号较弱,可能出现对终端设备提供服务出现中断的问题,此时执行后续步骤。其次,第一异频测量结果大于或等于第三阈值时,即反映第二小区的信道资源的信号较强,不会出现服务出现中断的问题,此时执行步骤S105。可以理解的是,具体第三阈值需要根据第二小区的具体第二频域带宽资以及第二小区的具体信道资源的信号强度的实际情况灵活确定。
S105、当第一异频测量结果大于或等于第三阈值时,则终端设备向网络设备发送第一异频测量结果。
本实施例中,在第一异频测量结果大于或等于第三阈值时,即第二小区的信道资源的信号较强,不会出现服务出现中断的问题,因此终端设备向网络设备发送步骤S104得到的第一异频测量结果。
S106、网络设备将终端设备从第一小区转移至第二小区。
本实施例中,网络设备接收到步骤S105所发送的第一异频测量结果之后,可以确定第二小区的信道资源的信号较强,即第二小区能够为终端设备提供服务,并不会出现服务出现中断的问题,此时网络设备将终端设备从第一小区转移至第二小区。
S107、网络设备基于第一小区建立第三小区。
本实施例中,由于步骤S106中网络设备将终端设备从第一小区转移至第二小区,此时第一小区内无终端设备,因此可以对第一小区的带宽进行调整,此时将第一小区的第一频域带宽资源重新配置为第三频域带宽资源,并且第一频域带宽资源以及第三频域带宽资源中具有相同频域带宽资源,然后在第三频域带宽资源的位置新建立一个小区,该小区即为第三小区,并且禁止第三小区被小区外终端设备接入,即不允许不属于第二小区对应的服务区域外的终端设备接入。具体地,第三频域带宽资源需包括支持发送CRS的RB。由于本实施例中在20M的第一频域带宽资源中已经基于高端5M频域带宽资源建立第二小区,此时可分配的第一频域带宽资源为15M,此时将可分配的第一频域带宽资源15M重新配置为10M,即第三频域带宽资源为10M。可以理解的是,前述示例仅用于理解本方案,不应理解为本申请的限定。
具体地,第三小区包括但不限于MIB,SIB,PDCCH,PDSCH以及PUSCH等信道资源,具体第三小区具体的信道资源此处不做限定。
进一步地,由于PCI MOD3相同,那么CRS发送的载波会产生同频干扰,为了避免第二小区与第三小区相互干扰,第二小区的PCI MOD3与第三小区需要错开,从而避免两个小区间相互干扰。
为了便于理解,请参阅图5,图5为本申请实施例中基于第一小区建立建立第三小区一个实施例示意图,如图5所示,C1指示第二小区,C2指示第二频域带宽资源,C3指示第一频域带宽资源,C4指示第三频域带宽资源,C5指示第三小区,通过步骤S102的方式在第二频域带宽资源C2上建立第二小区C1之后,需要在第一频域带宽资源C3中确定第三频域带宽资源C4,并且基于第三频域带宽资源C4建立第三小区C3。可以理解的是,图5的示例仅用于理解本方案,不应理解为本申请的限定。
S108、网络设备向终端设备发送第二消息。
本实施例中,网络设备通过步骤S107建立第三小区之后,需要确定第三小区能够对终端设备提供正常的服务,因此终端和设备还需要对处于第二小区对应的服务区域中的所有终端设备发送第二消息,第二消息指示第二小区对应的服务区域中的所有终端设备对第三小区的信道资源进行异频测量。
S109、终端设备根据第二消息对第三小区的信道资源进行异频测量,得到第二异频测量结果。
本实施例中,终端设备接收到步骤S108中网络设备所发送的第二消息之后,由于第二消息指示第二小区对应的服务区域中的所有终端设备对第三小区的信道资源进行异频测量,因此终端设备对第三小区的信道资源进行异频测量,并得到第二异频测量结果。具体地,终端设备对第三小区的MIB,SIB,PDCCH,PDSCH以及PUSCH等信道资源进行异频测量,得到第二异频测量结果。
进一步地,终端设备得到第二异频测量结果之后,需要判断第三小区是否能够对终端设备提供正常的服务,由于第二异频测量结果可以指示第三小区的信道资源的信号强度,因此第二异频测量结果小于第四阈值时,即反映第三小区的信道资源的信号较弱,可能出现对终端设备提供服务出现中断的问题,此时执行后续步骤。其次,第二异频测量结果大于或等于第四阈值时,即反映第三小区的信道资源的信号较强,不会出现服务出现中断的 问题,此时执行步骤S110。可以理解的是,具体第四阈值需要根据第三小区的具体第三频域带宽资以及第三小区的具体信道资源的信号强度的实际情况灵活确定。
S110、当第二异频测量结果大于或等于第四阈值时,则终端设备向网络设备发送第二异频测量结果。
本实施例中,在第二异频测量结果大于或等于第四阈值时,即第三小区的信道资源的信号较强,不会出现服务出现中断的问题,因此终端设备向网络设备发送步骤S109得到的第二异频测量结果。
S111、网络设备将终端设备从第二小区转移至第三小区。
本实施例中,网络设备接收到步骤S110所发送的第二异频测量结果之后,可以确定第三小区的信道资源的信号较强,即第三小区能够为终端设备提供服务,并不会出现服务出现中断的问题,此时网络设备将终端设备从第二小区转移至第三小区。进一步地,再去激活第二小区。由此能够在不影响下小区服务性能的情况下,完成小区频域带宽切换,减少频域带宽,由此降低能耗损失,并且在频域带宽切换的过程中不会导致服务中断的问题,由此提升服务质量。
二、小带宽切换至大带宽
为了便于理解,以第一小区对应的第一频域带宽资源为15M,第二小区对应的第二频域带宽资源为5M,第三小区的对应的第三频域带宽资源为20M作为示例进行介绍,请参阅图6,图6为本申请实施例中小区频域带宽切换的方法另一实施例示意图,如图6所示,小区频域带宽切换的方法包括如下步骤。
S201、当第一小区的小区负载大于第二阈值时,则网络设备在第一频域带宽资源中确定第二频域带宽资源,且停止在第二频域带宽资源上调度终端设备。
本实施例中,由于第一小区对应的第一频域带宽资源为15M,当第一小区的小区负载大于第二阈值时,即当前带宽可能无法满足容量诉求,因此需要将带宽增大以满足容量需求。由此,网络设备在第一频域带宽资源中确定第二频域带宽资源,此时第二频域带宽资源属于较低带宽资源,即网络设备闭塞15M中高端5M RB,并且停止在第二频域带宽资源上调度终端设备,即停止在闭塞的5M RB上调度终端设备。进一步地,网络设备还需要打孔第二频域带宽资源的CRS。
具体地,本实施例中第二阈值可以为60%或者70%等,具体第二阈值需要根据第一小区的具体第一频域带宽资以及第一小区的具体小区负载的实际情况灵活确定。
为了便于理解,请参阅图7,图7为本申请实施例中确定第二频域带宽资源另一实施例示意图,如图7所示,D1指示第一小区,D2指示第一频域带宽资源,D3指示第二频域带宽资源,在第一小区D1对应的第一频域带宽资源D2上闭塞第二频域带宽资源D3对应的RB,由此确定第二频域带宽资源D3,并且停止在第二频域带宽资源D2上调度终端设备,以及打孔第二频域带宽资源D3的CRS。可以理解的是,图7的示例仅用于理解本方案,不应理解为本申请的限定。
S202、网络设备基于第二频域带宽资源建立第二小区,其中,第二小区禁止被小区外终端设备接入,小区外终端设备不属于第一小区对应的服务区域。
本实施例中,网络设备在第二频域带宽资源的位置新建立一个独立的异频小区,该异 频小区即为第二小区,并且禁止第二小区被小区外终端设备接入,即不允许不属于第一小区对应的服务区域外的终端设备接入。此时第二小区的第二频域带宽资源为高频率5M,即第二频域带宽资源的范围可以为15M至20M。具体地,第二小区包括但不限于MIB,SIB,PDCCH,PDSCH以及PUSCH等信道资源,具体第二小区具体的信道资源此处不做限定。
进一步地,由于PCI MOD3相同,那么CRS发送的载波会产生同频干扰,为了避免第一小区与第二小区相互干扰,第二小区的PCI MOD3与第一小区需要错开,并且第一小区不在此5M频谱内调度,从而避免两个小区间相互干扰。
为了便于理解,请参阅图8,图8为本申请实施例中建立第二小区另一实施例示意图,如图8所示,E1指示第一频域带宽资源,E2指示第二频域带宽资源,E3指示第二小区,在第一频域带宽资源E1上通过步骤S201的方式确定第二频域带宽资源E2,并且停止在第二频域带宽资源E2调度终端设备,进一步地,基于第二频域带宽资源E2建立第二小区E3。可以理解的是,图8的示例仅用于理解本方案,不应理解为本申请的限定。
S203、网络设备向终端设备发送第一消息。

本实施例中,当第一异频测量结果大于或等于第三阈值时,则终端设备向网络设备发送第一异频测量结果的方式与步骤S105类似,在此不再赘述。

本实施例中,网络设备将终端设备从第一小区转移至第二小区的方式与步骤S106类似,在此不再赘述。
S207、网络设备基于第一小区建立第三小区。
本实施例中,由于步骤S206中网络设备将终端设备从第一小区转移至第二小区,此时第一小区内无终端设备,因此可以对第一小区的带宽进行调整,此时将第一小区的第一频域带宽资源重新配置为第三频域带宽资源,并且第一频域带宽资源以及第三频域带宽资源中具有相同频域带宽资源,然后在第三频域带宽资源的位置新建立一个小区,该小区即为第三小区,并且禁止第三小区被小区外终端设备接入,即不允许不属于第二小区对应的服务区域外的终端设备接入。具体地,第三频域带宽资源需包括支持发送CRS的RB。由于第一小区以及第二小区所处于的原始小区中的频域带宽总资源为20M,而本实施例中在15M的第一频域带宽资源中已经基于高端5M频域带宽资源建立第二小区,此时第一小区以及第二小区所处于的原始小区中可分配的频域带宽总资源为15M,此时将可分配的频域带宽总资源从10M重新配置为15M,即第三频域带宽资源为15M。可以理解的是,前述示例仅用于理解本方案,不应理解为本申请的限定。
具体地,第三小区包括但不限于MIB,SIB,PDCCH,PDSCH以及PUSCH等信道资源,具体第三小区具体的信道资源此处不做限定。
进一步地,由于PCI MOD3相同,那么CRS发送的载波会产生同频干扰,为了避免第二小区与第三小区相互干扰,第二小区的PCI MOD3与第三小区需要错开,从而避免两个小区间相互干扰。
为了便于理解,请参阅图9,图9为本申请实施例中基于第一小区建立建立第三小区另一实施例示意图,如图9所示,F1指示第二小区,F2指示第二频域带宽资源,F3指示第一频域带宽资源,F4指示第三频域带宽资源,F9指示第三小区,通过步骤S102的方式在第二频域带宽资源F2上建立第二小区F1之后,需要在第一频域带宽资源F3中确定第三频域带宽资源F4,并且基于第三频域带宽资源F4建立第三小区F3。可以理解的是,图9的示例仅用于理解本方案,不应理解为本申请的限定。
S208、网络设备向终端设备发送第二消息。
本实施例中,网络设备向终端设备发送第二消息的方式与步骤S108类似,在此不再赘述。
S209、终端设备根据第二消息对第三小区的信道资源进行异频测量,得到第二异频测量结果。
本实施例中,终端设备根据第二消息对第三小区的信道资源进行异频测量,得到第二异频测量结果的方式与步骤S109类似,在此不再赘述。
S210、当第二异频测量结果大于或等于第四阈值时,则终端设备向网络设备发送第二异频测量结果。
本实施例中,当第二异频测量结果大于或等于第四阈值时,则终端设备向网络设备发送第二异频测量结果的方式与步骤S110类似,在此不再赘述。
S211、网络设备将终端设备从第二小区转移至第三小区。
本实施例中,网络设备将终端设备从第二小区转移至第三小区的方式与步骤S111类似,在此不再赘述。
