接入方法、终端及网络侧设备
相关申请的交叉引用
本申请主张在2019年9月10日在中国提交的中国专利申请号No.201910853421.1的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及无线通信技术领域,尤其涉及一种接入方法、终端及网络侧设备。
背景技术
对于窄带通信系统,由于其系统带宽有限,因此能够用于随机接入的带宽也有限,从而会导致系统的容量受限。例如,窄带物联网(Narrow Band Internet of Things,NB-IoT)系统,其单载波带宽只有180KHz,为了提升NB-IoT系统的容量,可以给NB-IoT小区配置多个载波,即一个小区包括一个锚点(anchor)载波(也可以称为主载波)和若干个非锚点(non-anchor)载波(或称为辅载波),每个载波的带宽为180KHz。每个小区只能有一个anchor载波,anchor载波可以承载同步信号、广播信道、控制信道和数据信道,终端(User Equipment,UE)需要在anchor载波上接收和监控这些信息。Non-anchor载波只承载控制和数据信道、不承载同步和广播信道。因此空闲态的UE只能驻留在anchor载波上,随机接入的过程也只能在anchor载波上进行。终端只能在anchor载波(180KHz)上发起随机接入,这会导致需要支持海量连接的NB-IoT系统的容量受限。

具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚,下面将结合本公开实施例的附图,对本公开实施例的技术方案进行清楚、完整地描述。显然,所描述的实施例是本公开的一部分实施例,而不是全部的实施例。基于所描述的本公开的实施例,本领域普通技术人员所获得的所有其他实施例,都属于本公开保护的范围。
请参阅图1,图1为本公开实施例一提供的一种接入方法的流程示意图,该方法应用于终端,包括以下步骤:
步骤11:当驻留于第一小区的终端需要发起随机接入时,根据与所述第一小区关联的目标小区的相关信息,向所述目标小区发起随机接入。也就是说,如果所述终端驻留于第一小区且需要发起随机接入,则根据与所述第一小区关联的目标小区的相关信息,向所述目标小区发起随机接入。
需要说明的是,本公开实施例中所述的“关联”具体可以是指覆盖范围存在重叠,也就是说所述目标小区的覆盖范围与所述第一小区的覆盖范围存在重叠部分,并且在本公开实施例中,所述终端在发起随机接入时位于所述目标小区和所述第一小区的覆盖重叠区域内。
本公开实施例中,驻留于第一小区的终端可以向与该第一小区关联的另一小区,也即目标小区,发起随机接入。从而解决了由于第一小区的带宽有限导致的容量受限的问题,提升了所述第一小区对应的通信系统的容量。
另外,本公开实施例主要适用于所述终端需要从空闲态向连接态切换的场景。
下面举例说明上述接入方法。
可选的,所述目标小区的带宽大于所述第一小区的带宽。
也就是说,驻留在较窄的载波(例如NB-IoT载波)上的终端,可以在较宽的载波(例如NR载波)上发起随机接入。
本公开实施例中,所述终端可以为NB-IoT终端,所述第一小区可以为NB-IoT系统小区(其能用于随机接入的带宽只有180KHz),所述目标小区可以为新空口(New Radio,NR)系统小区(其能用于随机接入的带宽最小为5MHz)。当然,所述终端并不仅限于NB-IoT终端,所述第一小区也可以为其他的窄带通信系统小区,所目标小区也可以为除NR系统小区以外的宽带通信系统小区,例如长期演进(Long Term Evolution,LTE)系统小区等等,此处不再详细列举。
进一步可选的,可选的,所述目标小区的带宽和所述第一小区的带宽为用于随机接入的带宽。也就是说,本公开实施例中,所述目标小区中能够用于随机接入的带宽大于所述第一小区中能够用于随机接入的带宽。
可选的,所述目标小区的相关信息包括以下至少之一:
频率信息;
小区标识信息;
随机接入相关的信息。
本公开实施例中,小区标识信息可以是物理小区标识(Physical Cell Identifier,PCI)。所述随机接入相关的信息包括接入参数信息和接入资源信息中的至少一种。
可选的,所述向所述目标小区发起随机接入的步骤之前,还包括:
所述终端获取与所述第一小区关联的至少一个第二小区;
所述终端从所述至少一个第二小区中确定所述目标小区。
具体的,获取的是所述至少一个第二小区的相关信息,该相关信息包括频率信息和/或小区标识信息,当然也可以包括随机接入相关的信息。
进一步可选的,所述从所述至少一个第二小区中确定所述目标小区的步骤之前,还包括:
所述终端获取所述第一小区的信号强度和/或质量相关信息的预设门限和/或默认(default)第二小区;
所述预设门限为:用于从所述至少一个第二小区中确定所述目标小区的 判断门限;
所述默认第二小区为所述至少一个第二小区中的一个。
具体的,所述信号强度和/或质量相关信息可以是参考信号接收功率(Reference Signal Received Power,RSRP)。其他的可选实施方式中,所述信号强度和/或质量相关信息还可以是参考信号接收质量(Reference Signal Received Quality,RSRQ)或者接收信号强度(Received Signal Strength,RSS)或者信号与干扰加噪声比(Signal to Interference plus Noise Ratio,SINR)。当然,所述信号强度和/或质量相关信息还可以同时包括RSRP、RSRQ、RSS和SINR中的两个或者两个以上的组合。
本公开实施例中,所述预设门限是根据网络侧部署情况和/或确定目标小区的判断过程确定。
另外,所述默认第二小区是根据网络部署情况确定,例如可以是与所述第一小区共站部署的第二小区。设置默认第二小区的目的是减少终端的测量工作量,例如如果默认第二小区与第一小区共站部署,那么如果终端测量到第一小区的信号强度和/或质量相关信息(例如RSRP)大于一个门限值,就可以认为终端当前所处位置位于默认第二小区的覆盖范围内,或者说终端所能接收到的默认第二小区的下行信号强度满足接入条件。也可以这么说,如果默认第二小区与第一小区共站部署,那么如果终端测量到第一小区的信号强度和/或质量相关信息(例如RSRP)大于一个门限值,就可以认为如果终端对默认第二小区进行测量的话,测量到的信号强度和/或质量相关信息一定满足接入门限。
可选的,所述目标小区的相关信息、所述预设门限和所述默认第二小区中的至少之一是通过所述第一小区广播的系统消息下发。
也就是说,所述目标小区的相关信息可以所述第一小区广播的系统消息下发,所述预设门限也可以通过所述第一小区广播的系统消息下发,同样的,所述默认第二小区也可以通过所述第一小区广播的系统消息下发。
需要说明的是,如果所述目标小区是与所述第一小区关联的多个第二小区中的一个,那么所述目标小区的相关信息是与其他第二小区的相关信息一起通过所述第一小区的系统消息下发的,也就是说,所有与所述第一小区关 联的第二小区的相关信息都携带在所述第一小区的系统消息里。另外,如果所述第一小区的系统消息里携带了多个第二小区的相关信息,那么在确定目标小区后,可以根据目标小区的PCI在所述第一小区的系统消息中获取对应的随机接入相关的信息。
另外,如果与所述第一小区关联的第二小区只有一个的话,可以不需要在第一小区的系统消息里指示默认第二小区。也即,如果所述系统消息里只携带一个第二小区的相关信息,那么该第二小区就是目标小区,不需要指示该第二小区为默认第二小区。
可选的,所述从所述至少一个第二小区中确定所述目标小区的步骤包括:
若测量到所述第一小区的信号强度和/或质量相关信息大于或等于所述预设门限,所述终端将所述默认第二小区作为所述目标小区。
本公开实施例中,首先根据网络部署情况,确定一个第一小区的信号强度和/或质量相关信息的预设门限,该预设门限的确定原则是:如果终端测量到第一小区的信号质量信息大于或等于该预设门限,就可以认为默认第二小区是终端适合接入的小区。从而,如果测量到所述第一小区的信号强度和/或质量相关信息大于或等于所述预设门限,终端就不需要执行对第二小区的测量了,降低了终端的测量工作量。
可选的,所述从所述至少一个第二小区中确定所述目标小区的步骤包括:
若测量到所述第一小区的信号强度和/或质量相关信息小于所述预设门限,所述终端对所述至少一个第二小区进行测量并获取对应的信号强度和/或质量相关信息测量值;
所述终端从所述至少一个第二小区中选择信号强度和/或质量相关信息测量值最高的第二小区作为所述目标小区;或者,所述终端从所述至少一个第二小区中筛选出信号强度和/或质量相关信息测量值满足接入门限的第二小区,并从筛选出的第二小区中随机选择一个(第二小区)作为所述目标小区。
也就是说,终端通过测量来选择目标小区有以下两种方式:
一、选择信号强度和/或质量相关信息(例如RSRP)测量值最高的第二小区作为目标小区。
二、先筛选出信号强度和/或质量相关信息(例如RSRP)测量值满足接入门限的第二小区,如果有多个第二小区的信号强度和/或质量相关信息(例如RSRP)测量值满足接入门限,那么就从中随机选择一个作为目标小区。
当然,若测量到所述第一小区的信号强度和/或质量相关信息小于所述预设门限,为了降低终端的测量工作量,也可以不对默认第二小区进行测量,只对其他的第二小区进行测量,并根据测量结果从其他的第二小区中选择目标小区。
在其他的可选实施方式中,所述第一小区的信号强度和/或质量相关信息的预设门限可以为多个,与所述第一小区关联的第二小区也为多个。终端先测量得到所述第一小区的信号强度和/或质量相关信息测量值,然后根据所述第一小区的信号强度和/或质量相关信息测量值所满足的预设门限确定目标小区,也可以说,根据所述第一小区的信号强度和/或质量相关信息测量值所处的目标范围确定目标小区。多个预设门限对应多个信号强度和/或质量相关信息测量值的取值范围,所述目标范围为其中的一个。
具体的,如果所述第一小区的信号强度和/或质量相关信息测量值所处的目标范围只对应一个第二小区,则将该第二小区确定为目标小区。如果所述第一小区的信号强度和/或质量相关信息测量值所处的目标范围对应两个或者两个以上的第二小区,随机选择其中的一个作为目标小区,或者对这两个或两个以上的第二小区进行测量,并根据测量结果选择其中的一个作为目标小区。例如,从该两个或两个以上的第二小区中选择信号强度和/或质量相关信息测量值最高的第二小区作为所述目标小区;或者,从该两个或两个以上的第二小区中筛选出信号强度和/或质量相关信息测量值满足接入门限的第二小区,并从筛选出的第二小区中随机选择一个作为所述目标小区。
举例来说,所述第一小区的信号强度和/或质量相关信息(具体为RSRP)的预设门限有两个,RSRP1和RSRP2。与所述第一小区关联的第二小区有6个,小区A、小区B、小区C、小区D、小区E和小区F。如果第一小区的信号强度和/或质量相关信息测量值大于或等于RSRP2,那么对应小区A;如果第一小区的信号强度和/或质量相关信息测量值小于RSRP2且大于或等于RSRP1,那么对应小区B和小区C;如果第一小区的信号强度和/或质量相关 信息测量值小于RSRP1,那么对应小区D、小区E和小区F。因此,如果第一小区的信号强度和/或质量相关信息测量值大于或等于RSRP2,那么小区A即为目标小区。如果第一小区的信号强度和/或质量相关信息测量值小于RSRP2且大于或等于RSRP1,那么先对小区B和小区C进行测量,并得到对应的信号强度和/或质量相关信息测量值,然后从中选择信号强度和/或质量相关信息测量值较高的小区B作为目标小区;如果第一小区的信号强度和/或质量相关信息测量值小于RSRP1,那么先对小区D、小区E和小区F进行测量,并得到对应的信号强度和/或质量相关信息测量值,然后从中选择信号强度和/或质量相关信息测量值最高的小区E作为目标小区。
本公开实施例中的多个预设门限具体可以根据网络部署情况确定。设置多个预设门限,然后通过对第一小区的测量得到第一小区的信号强度和/或质量相关信息测量值,并判断该信号强度和/或质量相关信息测量值属于哪个范围(由预设门限确定),最后根据该信号强度和/或质量相关信息测量值所属的范围判断是否需要对第二小区进行测量,以及需要对哪些第二小区进行测量。从而,可以降低终端的测量工作。
根据上述可知,本公开实施例中,也可以不设置默认第二小区,直接根据终端的测量结果确定目标小区。一个预设门限可以对应多个第二小区,也就是说一个由预设门限确定的范围可以对应多个第二小区。
请参阅图2,图2是本公开实施例二提供的一种接入方法的流程示意图,该方法应用于网络侧设备,包括以下步骤:
步骤21:所述网络侧设备下发目标小区的相关信息,所述目标小区的相关信息用于驻留于第一小区的终端向所述目标小区发起随机接入,所述目标小区与所述第一小区相关联。
本公开实施例中,所述网络侧设备为所述第一小区对应的网络侧设备。
需要说明的是,本公开实施例中所述的“关联”具体可以是指覆盖范围存在重叠,也就是说所述目标小区的覆盖范围与所述第一小区的覆盖范围存在重叠部分,并且在本公开实施例中,所述终端在发起随机接入时位于所述目标小区和所述第一小区的覆盖重叠区域内。
本公开实施例中,驻留于第一小区的终端可以向与该第一小区关联的另 一小区,也即目标小区,发起随机接入,从而解决了由于第一小区的带宽有限导致的容量受限的问题,提升了所述第一小区对应的通信系统的容量。
另外,本公开实施例主要适用于所述终端需要从空闲态向连接态切换的场景。
下面举例说明上述随机接入方法。
可选的,所述目标小区的带宽大于所述第一小区的带宽。
可选的,所述目标小区的带宽和所述第一小区的带宽为用于随机接入的带宽。
本公开实施例中,所述终端可以为NB-IoT终端,所述第一小区可以为NB-IoT系统小区,相应的,所述网络侧设备可以为NB-IoT系统的网络侧设备。所述目标小区可以为新空口(New Radio,NR)系统小区。当然,所述终端并不仅限于NB-IoT终端,所述第一小区也可以为其他的窄带通信系统小区,所目标小区也可以为除NR系统小区以外的宽带通信系统小区,例如长期演进(Long Term Evolution,LTE)系统小区等等,此处不再详细列举。
可选的,所述目标小区的相关信息包括以下至少之一:
频率信息;
小区标识信息;
随机接入相关的信息。
可选的,所述下发目标小区的相关信息的步骤包括:
所述网络侧设备下发至少一个第二小区的相关信息,所述至少一个第二小区均与所述第一小区关联,所述目标小区为所述至少一个第二小区中的一个。
可选的,所述方法还包括:
所述网络侧设备下发所述第一小区的信号强度和/或质量相关信息的预设门限和/或默认第二小区;
所述预设门限为:用于从所述至少一个第二小区中确定所述目标小区的判断门限;
所述默认第二小区为所述至少一个第二小区中的一个。
可选的,所述至少一个第二小区的相关信息、所述预设门限和所述默认 第二小区中的至少之一是通过所述第一小区广播的系统消息下发。
也就是说,网络侧设备可以通过所述第一小区(也即终端的驻留小区)的系统消息下发所述至少一个第二小区的相关信息,也可以通过所述第一小区的系统消息下发所述预设门限,还可以通过所述第一小区的系统消息下发所述默认第二小区。
本公开实施例提供的是与上述实施例一对应的、具有相同发明构思的技术方案,且能达到相同的技术效果,详细可参阅上述实施例一,此处不再赘述。
本公开实施例三提供一种接入方法,如图3所示,该接入方法适用于以下场景:一NB-IoT终端当前驻留于一NB-IoT系统小区,与该NB-IoT系统小区关联的有三个NR小区(也即NR系统小区):与该NB-IoT系统小区共站的NR小区1,以及覆盖范围与该NB-IoT系统小区存在重叠的NR小区2和NR小区3。由于NB-IoT系统部署在低频(例如900MHz),而NR系统部署在中频(例如2.6GHz),因此NB-IoT系统小区的覆盖范围大于NR小区。
首先,网络侧设备在NB-IoT系统小区的系统消息中携带以下信息:
三个NR小区的频率信息、PCI和接入参数;
NB-IoT系统小区的RSRP门限,该RSRP门限用于选择目标小区;
NR小区1为默认的接入小区。
然后,当NB-IoT终端需要发起随机接入时,测量NB-IoT系统小区的RSRP。
最后,根据NB-IoT系统小区的RSRP测量值确定随机接入的目标小区。如果NB-IoT系统小区的RSRP测量值大于或等于RSRP门限,则表示NB-IoT终端在NR小区1的覆盖范围内,此时NB-IoT终端不需要测量NR小区,直接在NR小区1(默认的接入小区)发起随机接入。如果NB-IoT系统小区的RSRP测量值小于RSRP门限,则表示NB-IoT终端可能在NR小区2或NR小区3的覆盖范围内,此时NB-IoT终端开启对NR小区的测量,测量NR小区2和NR小区3的RSRP。如果NB-IoT终端测量到NR小区2的RSRP值较高(例如NB-IoT终端位于地点B),则在NR小区2发起随机接入;如果NB-IoT终端测量到NR小区3的RSRP值较高(例如NB-IoT终端 位于地点A),则在NR小区3发起随机接入。
本公开实施例四提供一种接入方法,如图4所示,该接入方法适用于以下场景:一NB-IoT终端当前驻留于一NB-IoT系统小区,与该NB-IoT系统小区关联的NR小区只有一个,这是由于NR系统和NB-IoT系统部署在同一个频段上且该NR小区与NB-IoT终端当前驻留的NB-IoT系统小区共站,因此它们的覆盖范围相同。
首先,网络侧设备在NB-IoT系统小区的系统消息中携带以下信息:
NR小区的频率信息、PCI和接入参数。
然后,NB-IoT终端需要发起随机接入时,不需要测量NR小区,直接在系统消息指示的NR小区发起随机接入。
