Description

小区重选优先级确定方法及装置、终端及存储介质 技术领域
本公开涉及一种小区重选过程中的频率优先级冲突解决技术，尤其涉及一种小区重选优先级确定方法及装置、终端(User Equipment，UE)及存储介质。
背景技术
当终端(User Equipment，UE)处于空闲态或非激活态时，需要持续地进行小区重选，以便驻留在优先级更高或者信号质量更好的小区。网络侧通过设置不同频率优先级，达到控制UE驻留的目的，并且UE将在某个频率上选择信号质量最好的小区，以便更好地为其提供服务。
小区重选可以分为同频小区重选和异频小区重选，同频小区重选主要用于解决无线覆盖问题，而异频小区重选既可以用于解决无线覆盖问题，也可以用于负载均衡。
在R17中，提出了支持基于切片的小区重选，基站通过系统信息块(System Information Block，SIB)消息或者无线资源控制释放(Radio Resource Control Release，RRC Release)消息下发切片/切片组及对应的频率优先级信息，UE的接入层(Access Stratum，AS)接收非接入层(Non-Access Stratum，NAS)指示的预期切片/切片组信息，并基于基站下发的切片重选信息执行切片重选，从而能够实现切片感知的小区重选，尽快重选到支持终端预期切片的小区驻留。
网络切片可以为特定用户提供一个完整的端到端虚拟网络。通过将网络资源划分为多个网络切片，5G网络切片可以为具有不同服务需求(如通信延迟、可靠性、容量、隔离以及其他功能)的用户提供差异化服务。运 营商网络将不但可以服务于以尽力而为(Best Effort)传输为通信需求特征的信息消费类业务，也可以满足以确定性传输为通信需求的生产控制类服务，为通信需求迥异的服务分配逻辑上或者物理上隔离的网络资源。一个网络切片由无线接入网(Radio Access Network，RAN)部分和核心网(Core Network，CN)部分组成。网络切片的实现依赖于不同切片的流量由不同的协议数据单元(Protocol Data Unit，PDU)会话(session)处理的原则。网络可以通过调度和提供不同的L1/L2配置来实现不同的网络切片。每个切片由单一网络切片选择辅助信息(Single Network Slice Selection Assistance Information，S-NSSAI)唯一标识，由切片/服务类型(Slice/Service Type，SST)和切片微分标识(Slice Differentiator，SD)等组成，NSSAI包括一个或多个S-NSSAI。

请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统， 该无线通信系统可以包括：若干个终端11以及若干个基站12。
其中，终端11可以是指向用户提供语音和/或数据连通性的设备。终端11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，终端11可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、终端(user device)、或用户终端(user equipment，UE)。或者，终端11也可以是无人飞行器的设备。或者，终端11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，终端11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是任一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，MTC系统。
其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(Central Unit，CU)和至少两个分布单元(Distributed Unit，DU)。集中单元中设置有分组数据汇聚协议 (Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站12的具体实现方式不加以限定。
基站12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，终端11之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to Pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
本公开实施例涉及的执行主体包括但不限于：蜂窝移动通信系统中的终端(UE，User Equipment)，以及蜂窝移动通信的基站等。
针对包含有小区切片的小区重选情形，目前协议中的频率重选方案是：重选频率优先级的确定，在不引入切片迭代的基础上，考虑所有NAS层提供的切片的切片特定频率优先级，以及Legacy频率优先级。
目前所支持的重选优先级确定方式如下：
重选优先级确定规则(Rule)1为支持高优先级切片的频率的相对频率优先级高于仅支持低优先级切片的频率的相对频率优先级。
Rule2为对于支持同一优先级切片/切片组的多个频率，其相对频率优先级是根据网络配置的切片特定频率优先级(sliceSpecificFrequencyPriority)确定。
如果网络侧没有为支持该切片的频率配置切片特定频率优先级，则在该频率在该切片中与其它频率之间的相对频率优先级为中作为最低相对频率优先级。
Rule3为支持切片的频率的相对频率优先级比不支持切片的频率的相对频率优先级高。对于不支持切片的多个频率之间的相对频率优先级，根据网络配置的legacy频率优先级(CellReselectionPriority)确定。
对于支持多切片的频率，按照上述重选优先级确定规则(Rule)确定的相对频率优先级可能会发生冲突，以下举例说明。
假设：切片优先级Slice1>Slice2；网络侧配置的支持切片的频率的频率优先级Slice1(F1>F2)，Slice2(F2>F3>F1)；本公开实施例中，网络侧配置的支持切片的频率的频率优先级是由网络侧配置的切片特定频率优先级确定的。其中，网络侧配置的切片特定频率优先级包括支持切片的频率的频率优先级。
根据Rule1确定的相对频率优先级为(F1，F2)>F3，而根据Rule2确定的相对频率优先级为F1>F2，F2>F3>F1；
这样，根据rule2确定的相对频率优先级F3>F1，与根据rule1确定的相对频率优先级F1>F3冲突。
另外，作为冲突的另一示例，假设：切片优先级Slice1>Slice2；
网络配置的切片相关的频率的频率优先级Slice1(F1>F2)，Slice2(F2>F1)；
根据Rule1确定的相对频率优先级为F1、F2均为高优先级，根据Rule2确定的相对频率优先级为F1>F2，F2>F1；
这样，F1和F2之间的相对频率优先级仍然无法确定。
本公开实施例正是针对上述实际的技术问题，通过下述技术方案进行相应的解决。以下详细阐述。
图2是根据一示例性实施例示出的小区重选优先级确定方法的流程示意图，如图2所示，本公开实施例的小区重选优先级确定方法由终端执行，包括以下处理步骤：

按照基于网络侧配置的所述频率优先级配置中的第一频率优先级配置确定的至少两个所述频率之间的相对频率优先级，与按照基于网络侧配置的所述频率优先级配置中的第二频率优先级配置确定的至少两个所述频率之间的相对频率优先级冲突。

所述第二频率优先级配置包括：网络侧配置的支持第二切片和/或第二切片组的不同频率之间的频率优先级。
本公开实施例中，所述频率优先级配置是由网络侧通过SIB消息和/或专有信令提供的，终端通过接收SIB消息和/或专有信令而获得前述的频率优先级配置。
步骤202，响应于基于至少两个所述频率优先级策略确定的至少两个相对频率优先级冲突，确定至少一个所述频率优先级策略，并基于确定的所述频率优先级策略确定冲突的所述频率之间的所述相对频率优先级。
确定至少一个所述基于协议确定的所述第二频率优先级确定准则，并按照该所述基于协议确定的所述第二频率优先级确定准则确定冲突的所述频率之间的所述相对频率优先级，包括：
基于支持的切片优先级确定至少两个所述频率之间的所述相对频率优先级，作为一种实现方式，支持高优先级切片的频率的相对频率优先级高于支持低优先级切片的频率的相对频率优先级；或者，作为一种实现方式，支持高优先级切片的频率的相对频率优先级高于仅支持低优先级切片的频率的相对频率优先级；或
忽略基于网络侧配置的至少两个所述频率之间的所述频率优先级确定所述至少两个所述频率之间的所述相对频率优先级；或
基于支持的切片优先级确定至少两个所述频率之间的所述相对频率优 先级，并对未确定的至少两个所述频率之间的所述相对频率优先级，基于网络侧配置的至少两个所述频率之间的所述频率优先级进行确定。
确定至少一个所述基于网络侧配置的频率优先级配置，并基于该所述基于网络侧配置的频率优先级配置确定冲突的所述频率之间的所述相对频率优先级，包括：
响应于两个切片和/或两个切片组的切片优先级不同，基于所述网络侧配置的支持所述高优先级的所述切片和/或所述切片组的不同频率之间的频率优先级确定至少两个所述频率之间的所述相对频率优先级；或
响应于两个切片和/或两个切片组的切片优先级相同，终端选择其中一个所述切片和/或切片组，基于所述网络侧配置的支持所述切片和/或切片组的不同频率之间的频率优先级确定至少两个所述频率之间的所述相对频率优先级。
本公开实施例中，具体地，确定所述频率之间的相对频率优先级冲突，包括：根据第一频率优先级确定准则确定的两个以上频率之间的相对频率优先级，与根据第二频率优先级确定准则确定的两个以上频率之间的相对频率优先级存在冲突。作为一种示例，所述第一频率优先级确定准则包括：按照支持的切片优先级确定频率的相对频率优先级，即基于支持的切片优先级确定至少两个所述频率之间的所述相对频率优先级；
作为一个实施例，所述第一频率优先级确定准则包括：
支持高优先级切片的频率的相对频率优先级高于支持低优先级切片的频率的相对频率优先级。

所述第二频率优先级确定准则包括：支持同一切片/切片组或同一优先 级切片/切片组的多个频率之间的相对频率优先级由网络侧配置确定。
本公开实施例中，终端基于频率优先级确定策略解决相对频率优先级冲突的多个频率之间的相对频率优先级。以切片优先级Slice1>Slice2，网络配置的切片的相关频率的频率优先级Slice1(F1>F2)、Slice2(F2>F3>F1)为例，此时，根据第一频率优先级确定准则，确定频率优先级为(F1，F2)>F3；根据第二频率优先级确定准则，确定频率优先级为F1>F2，F2>F3>F1，此时，根据第二频率优先级确定准则确定的频率优先级F3>F1与根据第一频率优先级确定准则确定的频率优先级F1>F3冲突。
此时，终端侧需要在频率优先级确定策略中选择出相应的频率优先级确定准则，以所选择的频率优先级确定准则来确定相对频率优先级。上述示例中，若终端选择第一频率优先级确定准则来确定频率之间的相对频率优先级，则可以明确确定相对频率优先级的顺序为：F1>F3。
本公开实施例中，针对基于频率优先级确定准则导致相对频率优先级冲突的情况，按照所确定的频率优先级策略确定所述相对频率优先级冲突的频率之间的相对频率优先级，包括：按照第一频率优先级确定准则确定所述频率之间的相对频率优先级；或者，忽略按照第二频率优先级确定准则确定的所述频率之间的相对频率优先级；或者，先按照第一频率优先级确定准则确定所述频率之间的相对频率优先级，对于第一频率优先级确定准则未确定的所述频率之间的相对频率优先级，按照第二频率优先级确定准则确定。
以切片优先级Slice1>Slice2，网络配置的切片特定频率优先级Slice1(F1>F2)、Slice2(F2>F1)为例，根据第一频率优先级确定准则，确定相对频率优先级为F1，F2均为高优先级，根据第二频率优先级确定准则，确定相对频率优先级为F1>F2，F2>F1，频率F1和F2之间的相对频率优先级无法明确，导致F1和F2之间的相对频率优先级冲突。
此时，终端侧需要在频率优先级确定策略中确定相应的频率优先级确定策略，以确定优先级冲突的频率之间的相对频率优先级。上述示例中，若终端选择按照支持的高优先级切片Slice1对应的频率的频率优先级来确定频率之间的相对频率优先级，则可以明确确定相对频率优先级的顺序为：F1>F2。
针对基于频率优先级配置导致相对频率优先级冲突的情况，按照所选择的策略确定所述相对频率优先级冲突的频率之间的相对频率优先级，包括：两个切片或切片组的优先级不同的情况下，以高优先级切片或切片组下配置的频率A和频率B的频率优先级确定频率A和频率B的相对频率优先级；或者，两个切片或切片组的优先级相同的情况下，所述终端在两个切片或切片组中选择一个切片或切片组下配置的频率A和频率B的频率优先级确定频率A和频率B的相对频率优先级。
本公开实施例中，终端通过所选择的频率优先级确定策略，为相对频率优先级冲突的频率确定出最终的相对频率优先级，并作为小区重选时驻留小区的依据。
本公开实施例的技术方案中，可以应用于切片或切片组中，文中所描述的以切片或切片组，均为可以包含切片和/或切片组的情况。
本公开实施例避免了小区重选时的错乱情况的发生，提升了终端在切片或切片组中小区驻留的合理性，以及终端在切片或切片组中的接入性能。
以下通过具体示例，进一步阐明本公开实施例的技术方案的实质。
当终端按照第一频率优先级确定准则确定频率间的相对频率优先级与按照第二频率优先级确定准则确定的频率间的相对频率优先级之间发生冲突时，在频率优先级确定准则中确定相应的频率优先级确定准则，按照所确定的频率优先级确定准则确定相对频率优先级冲突的频率之间的相对频率优先级。
这里，相对频率优先级之间发生冲突包括按照第一频率优先级确定准则和第二频率优先级确定准则所确定的频率A和频率B间的相对频率优先级关系不同，如出现以下三种相对频率优先级情形中的至少两种：频率A>频率B、频率A<频率B、频率A＝频率B，则意味着按照频率优先级确定准则A和频率优先级确定准则B所确定的相对频率优先级之间冲突。
本公开实施例中，作为一种示例，所述第一频率优先级确定准则包括：按照支持的切片优先级确定频率的相对频率优先级，即基于支持的切片优先级确定至少两个所述频率之间的所述相对频率优先级；
作为一个实施例，所述第一频率优先级确定准则包括：
支持高优先级切片的频率的相对频率优先级高于支持低优先级切片的频率的相对频率优先级。
作为一个实施例，所述第一频率优先级确定准则包括：
支持高优先级切片的频率的相对频率优先级高于仅支持低优先级切片的频率的相对频率优先级。
第二频率优先级确定准则为：支持同一切片/同一优先级切片的多个频率之间的相对频率优先级由网络侧配置确定。
当按照上述第一频率优先级确定准则与按照上述第二频率优先级确定准则确定的频率间的相对频率优先级之间发生冲突的情况下，终端采用以下任一方式确定频率间的相对频率优先级。
1、终端按照上述第一频率优先级确定准则确定频率间的相对频率优先级。
2、终端忽略根据上述第二频率优先级确定准则确定的频率间的相对频率优先级。
3、终端先按照上述第一频率优先级确定准则确定频率间的相对频率优先级，对于上述第一频率优先级确定准则没有确定的频率间的相对频率优 先级，按照上述第二频率优先级确定准则确定。
例如，以切片优先级Slice1>Slice2，网络配置的切片特定频率优先级Slice1(F1>F2)、Slice2(F2>F3>F1)为例，此时，根据第一频率优先级确定准则，确定相对频率优先级为(F1，F2)>F3；根据第二频率优先级确定准则，确定相对频率优先级为F1>F2，F2>F3>F1，此时，根据第二频率优先级确定准则确定的相对频率优先级F3>F1与根据第一频率优先级确定准则确定的相对频率优先级F1>F3冲突。若终端选择按照高优先级切片Slice1对应的频率的频率优先级来确定相对频率优先级，则可以明确确定频率之间的相对频率优先级的顺序为：F1>F2。
当终端按照第一频率优先级配置确定频率间的相对频率优先级与按照第二频率优先级配置确定的频率间的相对频率优先级之间发生冲突时，在频率优先级配置中确定相应的频率优先级配置，按照所确定的频率优先级配置确定相对频率优先级冲突的频率之间的相对频率优先级。
这里，相对频率优先级之间发生冲突包括按照第一频率优先级配置和第二频率优先级配置所确定的频率A和频率B间的相对频率优先级关系不同，如出现以下三种相对频率优先级情形中的至少两种：频率A>频率B、频率A<频率B、频率A＝频率B，则意味着按照频率优先级配置A和频率优先级配置B所确定的相对频率优先级之间冲突。
本公开实施例中，作为一种示例，第一频率优先级配置为：网络配置的针对切片或切片组A的不同频率之间的频率优先级。
第二频率优先级配置为：网络配置的针对切片或切片组B的不同频率之间的频率优先级。
当按照上述第一频率优先级配置与按照上述第二频率优先级配置确定的频率间的相对频率优先级之间发生冲突的情况下，终端采用以下任一方式确定频率间的相对频率优先级。
1、如果两个切片或切片组的切片优先级不同，终端以支持的高优先级切片或切片组下配置的频率A和频率B的优先级确定频率A与频率B的相对频率优先级。
2、如果两个切片或切片组的切片优先级相同，终端实现决定基于哪个切片或切片组下配置的频率A与频率B的优先级确定频率A与频率B的相对频率优先级。
本公开实施例中，在未声明或未明确记载的情况下，通过频率优先级确定策略如频率优先级配置和/或频率优先级确定准则确定的频率优先级是指相对频率优先级。
