为了满足垂直行业对延迟、移动性、可靠性、位置精度等方面的需求,需要对如何在接入网(RAN)支持垂直业务进行增强。一种方式为,基于网络切片(slicing)为不同需求的多个业务提供更低时延,更有目标性,更大的灵活性和更高的可扩展性服务。更具体地说,RAN侧的slicing可以使得应用程序提供商可以参与定制RAN的设计、部署和操作,更好地支持应用程序提供商的业务。
由于移动的原因,终端设备可以执行小区选择或小区重选,基于信道质量执行小区选择或小区重选时,选择或重选的小区可能不支持终端设备需求的切片(UE intended slice),而终端设备当前所在 的小区可能支持终端设备需求的切片,基于切片进行小区选择或重选,终端设备可能选择到支持终端设备需求的切片的小区,但同时可能导致终端设备失去覆盖范围,因此,如何兼顾终端设备的切片需求和终端设备的覆盖范围是一项急需解决的问题。

在另一些实施例中,若候选小区不满足切片条件(即条件3.2成立),但是小区的信道质量较优(即条件3.1不成立),此情况下,终端设备可以回退至基于第二准则执行小区选择或重选。
例如,若候选小区不支持切片,或候选小区不支持终端设备需求的切片,或候选小区支持的切片和终端设备需求的切片不匹配,但小区的信道质量大于或等于网络设备的切片对应的第一小区选择或重选门限,此情况下,终端设备可以回退至基于第二准则执行小区选择或重选。
又例如,若候选小区不支持切片,或候选小区不支持终端设备需求的切片,或候选小区支持的切片和终端设备需求的切片不匹配,候选小区的信道质量大于或等于网络设备的切片对应的第一小区选择或重选门限的时长大于或等于第一时长,此情况下,终端设备可以回退至基于第二准则执行小区选择或重选。

例如,若候选小区支持切片,或候选小区支持终端设备需求的切片,或候选小区支持的切片和终端设备需求的切片匹配,并且候选小区的信道质量大于或等于网络设备的切片对应的第一小区选择或重选门限,或者候选小区的信道质量大于或等于网络设备的切片对应的第一小区选择或重选门限的时长大于或等于第一时长,但是候选小区不支持第一准则,此情况下,终端设备可以回退至基于第二准则执行小区选择或重选。
在本申请另一些实施例中,如图4所示,所述S210还包括:
S215,在基于所述第一准则的小区选择或重选结果满足第三条件的情况下,在根据所述第一准则所确定的候选小区中确定小区选择或重选的目标小区。
可选地,在一些实施例中,根据所述第一准则所确定的候选小区可以包括终端设备测量的所有小区,或者,也可以包括满足第一准则中的部分条件的小区,本申请对此不作限定。
在本申请一些实施例中,根据第一准则所确定的候选小区进一步执行小区选择或重选确定目标小区时可以参考候选小区的信道质量,波束数量,频点优先级、候选小区的切片信息中的至少一项。
在一些实施例中,所述小区选择或重选的目标小区满足以下条件中的至少一种:
信道质量高于第二小区选择或重选门限、信道质量最优、波束数量最多、对应的频点优先级最高、支持切片、支持终端设备需求的切片信息、支持的切片信息与所述终端设备需求的切片信息匹配。
例如,根据第一准则执行小区选择或重选时可以首先根据切片对应的第一小区选择或重选门限执行小区选择或重选,在不存在信道质量大于或等于所述第一小区选择或重选门限的小区时,再根据第二小区选择或重选门限执行小区选择或重选。
作为示例,终端设备可以选择信道质量大于第二小区选择或重选门限的候选小区中选择信道质量最优的小区作为目标小区。
作为示例,终端设备可以选择候选小区中的信道质量大于第二小区选择或重选门限,并且支持终端设备需求的切片的小区作为目标小区。
又例如,在小区的信道质量不满足第一小区选择或重选门限的情况下,终端设备可以根据结合切片信息进行选择,例如,在信道质量不满足第一小区选择或重选门限的候选小区中,选择支持切片,或者支持终端设备需求的切片,或者支持的切片和终端设备需求的切片匹配的小区作为目标小区,从而能够满足终端设备的切片需求。
在本申请一些实施例中,小区的信道质量可以为小区的测量结果,例如参考信号接收功率(Reference Signal Receiving Power,RSRP)、参考信号接收质量(Reference Signal Receiving Quality,RSRQ)、信号干扰噪声比(Signal to Interference plus Noise Ratio,SINR)、信道质量指示(Channel Quantity Indicator,CQI)、信号噪声比(Signal to Noise Ratio,SNR)等。
在本申请另一些实施例中,小区的信道质量也可以是根据小区的测量结果进行调整得到的信道质量信息,例如可以将小区的测量结果加上特定调整量,确定为小区的信道质量信息。可选地,该特定调整量可以根据小区的切片信息确定。
例如,若小区支持终端设备需求的切片信息,则对应的调整量可以为第一调整量,或者,若小区不支持终端设备需求的切片信息则对应的调整量为第二调整量,其中,所述第一调整量大于第二调整量。
举例说明,若候选小区中的第一小区的信道质量为X1,对应的调整量为delt1,则该第一小区的目标信道质量为X1+delta1,第一小区的信道质量为X2,对应的调整量为delta2,则该第二小区的目标信道质量为X2+delta2,其中,第一小区支持终端设备小区的切片信息,第二小区不支持终端设备小区的切片信息,第一小区的信道质量X1低于第二小区的信道质量X2,但是,delta1大于delta2,若X1+delta1大于X2+delta2,则可以选择第二小区作为目标小区,否则,选择第二小区作为目标小区。
本申请实施例通过结合小区的切片信息对小区的信道质量信息进行微调,进一步在结合信道质量信息进行小区选择或重选时,相当于同时考虑终端设备的切片需求和小区的信道质量,有利于满足终端设备的切片需求和覆盖范围。
