以下结合附图对本发明的优选实施例进行详细说明, 应当理解, 以下 所说明的优选实施例仅用于说明和解释本发明, 并不用于限定本发明。
随着通信技术的发展, 出现了多种通信技术,例如长期演进( Long Term Evolution, LTE ) 通信技术。 所述 LTE是由第三代合作伙伴计划 (The 3rd Generation Partnership Project, 3 GPP ) 组织制定的通用移动通信系统 ( Universal Mobile Telecommunications System, UMTS )技术标准的长期演 进。 LTE 系统引入了正交频分复用 ( Orthogonal Frequency Division Multiplexing, OFDM )和多输入多输出( Multi-Input & Multi-Output, MIMO ) 等关键传输技术, 显著增加了频谙效率和数据传输速率。
LTE第一阶段技术, 于 2008年底完成标准化并在 2009年开始进行商 用网络部署(对应 3GPP R8 9版本; R8及 R9为两种不同的通信协议;)。 为满足未来无线通信市场的更高需求和更多应用, 同时还保持对 LTE较好 的后向兼容性, 3GPP 在 2010 年启动了 LTE的演进版本 LTE-Advanced ( LTE-A ) 的研究 (对应 3GPP R10及后续版本)。 LTE-A采用了载波聚合 ( Carrier Aggregation )、 上 /下行多天线增强 ( Enhanced UL/DL MIMO )、 多 点协作传输( Coordinated Multi-pomt Tx&Rx )、 中继 ( Relay )、 异构网千扰 协调增强 ( Enhanced Inter-cell Interference Coordination for Heterogeneous Network )等关键技术, 能大大提高无线通信系统的峰值数据速率、 峰值频 谱效率、 小区平均 i "效率以及小区边界用户性能, 同时也能提高整个网絡 的组网效率。
由于商用网络部署与 LTE标准技术演进的平行推进, 目前市场上广泛 存在着釆用不同版本的基站与釆用不同协议版本的终端共存的情况。 考虑 到不同协议版本功能上的差异, 基于不同协议版本的设备在功能上也会有 较大差异 (即使是基于相同的协议版本, 考虑到制造成本、 目标市场等因 素, 不同的基站、 终端在支持的功能上也可能有较大区别), 而终端在某基 站下能够发挥的最大能力取决与终端与基站能力的交集。 例如基于 3GPP R11版本技术的基站相对于基于 3GPP R9版本技术的基站而言, 采用 R11 协议版本的基站能够支持载波聚合, 8 x 8 下行 MIMO / 4 X 4 上行 MIMO 等功能, 可以提供更高的传输速率及效率。 但是, 这些功能必须要配合支 持这些功能的 R11终端才能有效的发挥。 由于根据目前的协议描述, UE在 进行小区选择、 重选时并不会考虑终端、 基站间的能力匹配问题, 基站无 法为不同能力的 UE配置不同的小区选择重选参数,终端也无法通过系统消 息获知基站的具体能力, 因此也无法做到根据设备能力有针对性的驻留。 如果大量 R9的终端驻留在了 R11基站所辖小区内, 或者大量 R11终端驻 留在了 R9基站所辖小区内, 终端和基站由于版本、 能力的不匹配会导致设 备能力无法有效发挥从而造成传输效率、 速率的下降, 对用户体验有较大 负面影响。
综合上述导致通信终端无法正常发挥通信能力、 通信质量差的原因是 通信终端驻留在不适于其发挥通信能力的小区中, 根据上述分析, 本发明 实施例提供了一种基于终端能力的小区选择重选参数确定方法、 基站、 终 端及通信系统, 以使终端尽可能的驻留在与其通信能力相适配的小区中, 从而提升通信质量及用户使用满意度。
实施例一: 如图 1 所示, 本实施例提供一种小区选择重选参数确定方法, 所述方 法包括:
步骤 S110: 依据终端能力参数设置至少两套小区选择重选参数; 步骤 S120: 发送所述至少两套小区选择重选参数;
其中, 所述至少两套小区选择重选参数中与终端的终端能力参数匹配 的一套小区选择重选参数, 用于所述终端的小区选择和 /或重选。
在具体的实现过程中, 指向所述步骤 S110至所述步骤 S120的执行主 体通常可为基站或与基站相连的网元; 具体的所述基站可为演进型基站 e肌
在所述步骤 S110中, 配置小区选择重选参数的配置设备可以预存储不 同终端的终端能力参数, 具体的依据不同类型终端所对应的通信协议不同 获取所述终端能力参数。 如根据统计数据认为活动在第一基站覆盖范围内 的终端通常包括 3种类型的终端; 所述基站 A预先通过外设或管理人员的 手动输入可获取上述 3 不同终端的终端能力参数, 在配置小区选择重选参 数时, 针对 3不同终端的终端能力参数配置 3套小区选择重选参数。
在配置完所述小区选择重选参数后, 基站 A将所述 3套小区选择重选 参数发送给在基站 A覆盖范围内的所有终端, 以便具体的某一个终端根据 自身的终端能力参数选取其中的一套终端能力参数, 进行小区重选, 从而 驻留或切换到适合其的小区内, 以尽可能的发挥通信终端的通信能力, 提 升通信质量及用户满意度。
通常在具体的实现过程中, 由于终端的类型是有限的且是可以预先知 道的, 故在配置所述小区选择重选参数时, 基站无需知道具体某一个终端 的终端能力参数; 基站将根据当前的网络配置参数以及的终端能力参数配 置小区选择重选参数。 所述网络配置参数包括基站 A覆盖形成的第一小区 的通信工参以及第二小区的工参。 第二小区可为所述第一小区的邻区或同 一地理范围下的不同频率覆盖形成的小区。
在当前的通信状况下, 基站 A发现 A类型终端在第二小区中可以更好 的发挥通信终端的通信能力, 基站 A可配置一套小区选择重选参数, 使终 端在接收到所述小区选择重选参数后, 使驻留在第一小区的 A类型终端切 换至第二小区中。 在具体配置所述重选参数时, 还可以综合考虑各小区的 负载参数, 进行负载均衡处理等。
具体的所述小区选择重选参数用于终端的小区选择和 /或重选包括: 当 终端首次进入网络时, 所述小区选择重选参数用于终端选择小区进行驻留; 当终端非首次进入网络时, 所述小区选择重选参数用于小区进行小区的重 选。
本实施例所述的小区选择重选参数确定方法, 相对于现有通信技术中 基站同一配置一种小区选择重选参数发送给终端, 显然本实施例所述的方 法有利于终端才艮据自身能力选择更适合自身通信能力发挥的小区选择重选 参数, 进而驻留在更加适合所述终端的小区中, 以提升通信质量及用户使 用满意度。
优选地, 所述步骤 S120包括:
将所述至少两套小区选择重选参数承载在 RRC消息中发送。
所述 RRC为无线资源控制协议(Radio Resource Control ); 所述 RRC 消息为无线资源控制协议消息, 是通信过程中终端与基站之间建立 RRC连 接所使用的消息。
优选地, 所述 RRC消息为 RRC重配置消息、 RRC释放消息或 RRC连 接建立拒绝消息或系统消息。
在具体的实现过程中, 所述小区选择重选参数还可承载在系统消息中 或专门为发送小区选择重选参数的专用消息中发送给终端; 终端在对应的 消息上接收所述小区选择重选参数。 将所述小区选择重选参数承载在 RRC消息中发送给终端, 实现简便, 基站与终端之间信息交互的次数少, 从而有利于降低基站的负载以及终端 的功耗。
优选地, 所述步骤 S 120还可以釆用广播或组播或专用信令发送将所述 小区选择重选参数。
所述广播信号和组播信号都是基站将一次性将同一信号发送给多个终 端; 不同的是广播信号是发送给所有能接收到所述信号的终端; 组播是发 送给指定的多个终端, 釆用广播或组播方式有利于减少基站发送的次数, 降低基站的发送负载。
所述系统消息即为所述广播信令, 所述 RRC消息为 RRC重配置消息、 RRC释放消息或 RRC连接建立拒绝消息即为所述专用信令。
如图 所示, 所述步骤 S110的实现方式有多种, 以下提供两种优选方 式:
方式一:
所述步骤 S110可包括:
步骤 S111 : 预先设置至少一个配置索引信息; 每一个所述配置索引信 息包括至少一个配置索引; 一个所述配置索引对应一种终端能力参数; 步骤 S112: 依据每一个所述配置索引信息预先配置一套小区选择重选 步骤 S113: 当终端能力参数与一个配置索引信息中至少一个或全部配 置索引相对应时, 确定所述配置索引信息所对应的一套小区选择重选参数 为所述至少两套小区选择重选参数中一套。
在具体的执行过程中, 当终端能力参数与一个配置索引信息中全部配 置索引相对应时, 确定所述配置索引信息所对应的一套小区选择重选参数 为所述至少两套小区选择重选参数中一套。 具体的如终端可对应两种终端能力, 对应了二种终端能力参数分别为 终端能力参数一及终端能力参数二。 为了简化终端能力参数一及终端能力 参数二的表示, 可分别为终端能力参数一及终端能力参数二设置一个配置 索引; 两个配置索引将构成所述配置索引信息; 综合考虑一个配置索引信 息中各种终端能力参数形成一套小区选择重选参数; 在为不同终端配置小 区选择重选参数时, 若终端的一个终端能力参数或多个终端能力参数是上 述配置索引信息所对应的, 则将对应于该配置索引信息的一套小区选择重 选参数确定向终端发送的至少两套小区选择重选参数之一。 具体如, 当终 端 A的具有终端能力参数一所表征的终端能力, 终端 B具有终端能力参数 二所表征的终端能力, 终端 C具有终端能力参数一及终端能力参数二所表 征的终端能力, 终端 D既不具有终端能力参数一所表征的终端能力, 也不 具有终端能力参数二所表征的终端能力。 根据上述步骤 S111 , 则适用于终 端 A、 终端 B及终端 C配置的小区选择重选参数可为上述同时对应于终端 能力参数一及终端能力参数二的小区选择重选参数; 而终端 D适用其他套 的小区选择重选参数。
在具体的实现过程中, 基站事先针对不同的终端能力参数根据当前的 网络配置参数, 预先配置对应的小区选择重选参数。 其中, 不同的终端能 力参数表征的是基站的不同能力或相同能力的能力程度。
基于上述方案, 所述配置索引信息为比特位图; 每一所述比特位图中 的至少一个或多个比特为对应一个终端能力参数的所述配置索引。
具体的所述比特位图中的每一个比特表示终端是否具有或支持该终端 能力参数所对应的终端能力。 具体的终端是否支持载波聚合可以用一个比 特来表示; 若支持载波聚合的频段包括 N个, 则可为每一个频段分配一个 比特, 用对应比特的两种状态表示在该频段是否支持载波聚合。 在具体的 实现过程中, 所述比特位图中的一个配置索引也可以用若干比特来表示, 如支持载波聚合的频段分为 N个; N=2n, 则可用 n个比特的组合指示支持 不同的载波聚合频段。
在具体的实现过程中所述配置索引信息还可以用其他的方式表示, 如 一个字段或包括配置索引与终端能力参数的映射表格等方式。
本实施例中将所述配置索引信息为一个比特位图; 采用比特位图来表 示配置索引信息, 信息量少, 简单易行。
方式二:
所述步骤 S110可包括:
预先根据不同的终端能力参数或终端能力参数集合设置一套或多套小 区选择重选参数; 其中, 所述终端能力参数集合包括至少一个终端能力参 数;
将终端能力参数与小区选择重选参数的对应关系包含在通信协议中; 依据所述通信协议确定至少两套小区选择重选参数;
相应地,
所述发送所述至少两套小区选择重选参数为:
依据所述通信协议发送预先配置的至少两套所述小区选择重选参数。 釆用本方式配置多套小区选择重选参数时, 通常每一个能力参数集合 仅对应一套小区选择重选参数, 而一套小区选择重选参数可能对应多个小 区选择重选参数集合。
将终端能力参数与小区选择重选参数的对应关系, 即完成了静态配置, 基站发射小区选择重选参数之前, 仅需获取通信协议直接发送即可, 从而 实现简便快捷; 对应终端侧也可以简便的根据通信协议中的对应关系, 在 接收到两套或多套小区选择重选参数之后, 选择跟自身能力相适配的一套。
优选地, 所述方法还包括:
形成指示信息; 所述指示信息用于指示每一套所述小区选择重选参数 发送所述指示信息。
所述指示信息可以与每一套小区选择重选参数同步形成, 也可以是在 形成每一套重选参数之后或之前形成。
在具体的执行过程中, 当所述小区选择重选参数是依据配置索引信息 配置形成的时候, 则形成所述指示信息可以为获取每一套所述小区选择重 选参数所对应的配置索引信息; 所述指示信息包括所述配置索引信息或为 所述配置索引信息。 所述指示信息的具体构成可为多种, 具体如比特位图 等。
发送所述指示信息可与每一套小区选择重选参数同步发送, 也可以在 发送所述小区选择重选参数之前或之后发送。

第一部分可包括第 m套小区选择重选参数的索引及对应第 m套小区选 择重选参数对应的第 m终端能力参数的索引; 第二部分可为表征小区选择 重选参数的索引与终端能力参数的索引的映射关系。 所述指示信息可为映 射关系表。
在本实施例中, 通过所述指示信息的发送可便于终端根据指示信息及 自身的终端能力参数确定一套适合于终端通信的小区选择重选参数。
具体的如, 一套所述小区选择重选参数以多个字段表示时, 可在表示 该套小区选择重选参数的字段中增加至少一个或全部比特来表示所述指示 信息; 所增加的比特表示对应于该套小区选择重选参数的终端能力参数; 这种表示方式简便, 信息量少, 且终端可以简便的获取对应于该套小区选 择重选参数的终端能力参数。
所述指示信息所指示的终端能力参数的具体构成以及与所述终端能力 参数相适配的通信参数可以通信协议的方式存储在终端以及基站中。
此外, 基站还可发送默认小区选择重选参数;

所述默认小区选择重选参数为采用现有方法配置的小区重选参数, 可 以与步骤 S110中的所述至少两套小区选择重选参数一起发送, 也可以单独 发送。 所述默认小区选择重选参数在配置的过程中没有以终端能力参数为 依据。 通过默认小区选择重选参数的发送, 方便终端的终端能力参数与步 骤 S110中的至少两小区选择重选参数相对应时选择默认的小区选择重选参 数进行小区选择或重选。
优选地,
所述依据不同终端的能力设置不同的小区选择重选参数为:

本实施例所述的终端为实施例三中所述的小区选择重选参数确定方法 提供了具体的硬件支持, 可用来实现实施例三中任意的技术方案, 能有效 的提升通信质量及用户满意度。
以下结合上述任意实施例提供几个具体应用示例。
示例一:
如图 8所示的通信系统, 包括第一基站、 第二基站、 终端 UE A1及终 端 UE B1 ; 其中, 第一基站覆盖形成了小区 CELL A1 ; 第二基站覆盖形成 了小区 CELL B1;小区 CELL A1与 CELL B1部分重叠覆盖。当前终端 UE A1 及终端 UE B1位于所述重叠覆盖区域内。 所述第一基站和所述第二基站都 可为演进型基站 eNB。
小区 CELL A1 使用频点 A且支持功能 1 ;小区 CALL Bl 使用频点 B 且不支持功能 1 ; UE A1 支持功能 1 ; UE B1 不支持功能 1 。
UE A1及 UE B1 均处于 IDLE状态, 在邻近或相同的地理位置,且目前 都驻留在 CELLA1中。
eNB 确定小区选择重选参数,并在系统消息中广播 (也可通过 RRC重配 之、 RRC释放、 RRC拒绝等消息发送给 UE)。
其中, 系统消息中除了携带普通的小区选择重选参数外, 还携带为了为 功能 1定制的小区选择重选参数: 适用于功能 1 的终端专用频率优先级。 在普通的小区选择重选参数中, CELLA1所在频点优先级低与 CELL B1所 在频点优先级。 eNB为了使得支持功能 1的 终端能够驻留在 CELL A1从 而获得更好的服务,通过每个频点的"适用于功能 1的 UE专用频率优先级" 指示 CELL A1所在频点优先级高于 CELLB1所在频点的频点优先级。
终端在 CELL A1中接收到系统消息后,判断自身具有的功能是否有专门 的小区选择重选参数, 如果有则使用与自身功能对应的专有小区选择重选 参数, 否则即使用普通的小区选择重选参数。
由于 UE A1支持功能 1 , UE A1将采用 "适用于功能 1的 UE专用频率 优先级,, (其他小区选择重选参数由于没有为功能 1配置特殊的取值, 因 此依然使用与 UE能力无关的普通的小区选择重选参数 ), 并认为 CELL A1 所在频点拥有更高的优先级, 并继续驻留在 CELL A1中; 而 UE B1由于并 不支持功能 1,因此 UE B1将使用普通的小区选择重选参数,认为 CELL B1 拥有更高的优先级, 因此 UE B1将进行小区重选并驻留在 CELL B1内。
其功能专属的小区选择重选参数还可以针对至少一个或全部载频 和 /或 至少一个或全部小区,针对不同 UE能力分别配置以下参数中的至少一个或 全部:
频点优先级( absolute priority )、 最低接收 RSRP门限( Q-RxLevMin )、 最低接收 RSRQ门限( Q-QualMm ) 、 更高优先级选择门限( threshX-High )、 更低优先级选择门 限 ( threshX-Low ) , 速度状态 因 子 ( SpeedStateScaleFactors ), 禁止接入小区 ( BlackCellList ) 、 针对频点的 offset ( q-OffsetFreq )及针对小区的 offset ( q-OffsetCell )。 其中, 对于功能 专属的小区选择重选参数中没有出现的参数, 终端仍然使用普通的小区选 择重选参数中对应参数的取值。
功能 1可以是下列功能中的一种或多种组合:
终端对 CA的支持情况 (是否支持 CA和 /或终端在那些频段( BAND ) 上支持 CA)、 终端的能力等级(ue-category, 在协议 36。 306中定义。 可以 本实施例中, 功能可定义为终端支持某 category 或者终端支持高于某一 category 的能力等级。 也可以分上下行分别定义)、 终端是否支持 SMALL CELL dual connectivity

示例二:
如图 9所示的通信系统, 包括第三基站、 第四基站、 终端 UE A2、 终 端 UE B2及终端 UE C2; 其中, 第三基站覆盖形成了小区 CELL A2; 第四 基站覆盖形成了小区 CELL B2; 小区 CELL A2与 CELL B2部分重叠覆盖。 终端 UE A2、 终端 UE B2及终端 UE C2均位于所述重叠覆盖区域内。 所述 第三基站和所述第四基站都可为演进型基站 e B。
以下是个小区的网络配置参数包括: CELL A2 使用频点 A且支持功能 1 和 功能 2及 CALL B2 使用频点 B且不支持功能 1 和 功能 2。
以下各终端的终端能力参数; UE A2 支持功能 1 和 功能 2、 UE B2 不 支持功能 1 和 功能 2及 UE C2 支持功能 1但是不支持功能 2。
终端 UE A2、 终端 UE B2及终端 UE C2均处于 IDLE状态, 且均为与 两个小区的重叠覆盖区域内, 且假设当前三个终端获得的来自两个基站的 各种信号强度都相等, 且目前都驻留在小区 A中。
形成 CELL A2的基站为支持功能 1 和 /或 功能 2的终端制定了独立的 小区选择重选参数, 并在系统消息中广播。
其中, 系统消息中携带了两套小区选择重选参数: 一套为小区选择重 选参数 A; 另一套为小区选择重选参数 B;
其中,小区选择重选参数 B中包含了 8bit的 bitmap,且协议约定 bitmap 的第一个 bit ( bit 0 )表示是否支持功能 1, 第二个 bit ( bit l )表示是否支 持功能 2, 其余 bit为保留 bit。 在示例中, bit 0 和 bit 1被设置为 1 , 表示 小区选择重选参数组适用于支持功能 1 和 /或支持 功能 2的终端 (支持任 一一个即可)。
e B为了使得支持功能 1 和或功能 2的终端能够驻留在 CELL A2从而 获得更好的服务,在小区选择重选参数 A中配置 CELLA2所在频点优先级 低于 CELL B2所在频点优先级; 而在小区选择重选参数 B中, CELL A2所 在频点的频点优先级高于 CELL B2所在频点的频点优先级。
终端在 CELL A2中接收到系统消息, 判断自身是否拥有系统消息中终 端能力 bitmap中所指示的能力。 如果终端拥有 bitmap中指示为 1的能力中 的任意一种(本实施例中功能 1和功能 2 ), 则终端使用 bitmap所对应的小 区选择重选参数; 否则, 终端使用不包含 bitmap的那一套小区选择重选参 数。
由于 UE A2支持功能 1和功能 2, UE A2将釆用小区选择重选参数 B, 并认为 CELL A2所在频点拥有更高的优先级, 并继续驻留在 CELL A2中。
UE B2由于并不支持功能 1和功能 2, 因此 UE B2将使用小区选择重 选参数 A, 认为小区 B拥有更高的优先级, 因此 UE B2将进行小区重选并 驻留在 CELL B2上。
UE C2 由于支持功能 1 , 虽然不支持功能 2, 但是由于功能 1可以与 bitmap中的功能匹配, UE C2也将采用小区选择重选参数 B, 并认为 CELL A2所在频点拥有更高的优先级, 从而继续驻留在 CELLA2中。
本示例中所述的 bitmap即可认为是实施例一至实施例六中所述的指示 消息。
小区选择重选参数 B 中除了频点优先级外, 对于至少一个或全部载频 和 /或 至少一个或全部小区,针对不同终端的能力还可以分别配置以下参数 中的至少一个或全部:
最低接收 RSRP 门限 ( Q-RxLevMin )、 最低接收 RSRQ 门限 ( Q-QualMin ) 、 更高优先级选择门限(threshX-High )、更低优先级选择 门限( threshX-Low )
速度状态因子( SpeedStateScaleFactors )、 禁止接入小区( BlackCellList ) 及 针对频点的 offset ( q-OffsetFreq )、 针对小区的 offset ( q-OffsetCell )。
示例三:
如图 10 所示的通信系统包括第五基站、 第六基站、 第七基站、 终端 UE A3、 终端 UE B3及终端 UE C3; 其中, 第五基站覆盖形成了小区 CELL A3 ; 第六基站覆盖形成了小区 CELL B3; 第七基站覆盖形成了小区 CELL C3; 小区 CELL A2、 CELL B2及 CELL C3部分重叠覆盖。 终端 UE A3、 终 端 UE B3及终端 UE C3均位于所述重叠覆盖区域内。 所述基站均可为演进 型基站 e B。
以下是小区的网络配置参数:
CELL A3 使用频点 A且支持功能 1 和 功能 2;
CALL B3 使用频点 B , 不支持功能 1 , 但不支持功能 2;
CALL C3 使用频点 不支持功能 1 和 功能 2。
以下是各终端的能力:
UE A3 支持功能 1 和 功能 2;
UE B3 不支持功能 1 和 功能 2;
UE C3 支持功能 1但是不支持功能 2。
三个终端 均处于 IDLE状态, 假设处于相同的地理位置, 且目前都驻留 在 CELL A3中。 UE对 CELL A/B/C的测量结果相同。
e B在 CELL A3中为支持功能 1 和 /或 功能 2的终端制定了独立的小 区选择重选参数, 并在系统消息中广播。 其中, 系统消息中携带了 3套小区选择重选参数: 分别是小区选择重选 参数 1、 小区选择重选参数 2及小区选择重选参数 3; 小区选择重选参数 2 及小区选择重选参数 3中对应了 8bit的 bitmap, 且协议约定 bitmap的第一 个 bit ( bit 0 )表示是否支持功能 1, 第二个 bit ( bit 1 )表示是否支持功能 2, 其余 bit为保留 bit。
在示例中, 小区选择重选参数 2中的 bit 0 和 bit 1被设置为 1 (表示该 组参数适用于同时支持功能 1和功能 2的 UE ), C组参数中的 bit 0 被设置 为 1 而 bitl被设置为 0 (表示参数组适用于支持功能 1但不支持功能 2的 UE )。
e B在小区选择重选参数 1中配置 CELL A3所在频点优先级低于 CELL B3 及 CELL C3 所在频点优先级, 为 CELL C3 配置一个专用偏移 ( q-OffsetCell ) 为 18db且不为 CELL B3配置专用的偏移 ( q-OffsetCell )。 在小区选择重选参数 2中, CELL A3所在频点的频点优先级高于 CELL B3及 CELL C3所在频点的频点优先级;
在小区选择重选参数 3 中, eNB 配置 CELL A3 所在频点优先级低于 CELL B3及 CELL C3所在频点优先级, 且为 CELL B3配置一个专用的偏 移 ( q-OffsetCell ) 18db, 且为 CELL C3配置一个专用偏移 ( q-OffsetCell ) 为 -2db。
终端在 CELL A3中接收到系统消息,判断自身是否拥有系统消息中其能 力 bitmap中所指示的能力。 如果终端拥有所有 bitmap中指示为 1的能力, 则 UE使用 bitmap所对应的小区选择重选参数;如果终端检查完所有 bitmap 后发现没有完全匹配的 bitmap, 则终端使用不包含 bitmap的那一组小区选 择重选参数。
终端 A3由于支持功能 1和功能 2, UE A3将小区选择重选参数 2, 认为 CELL A3所在频点拥有更高的优先级, 并继续驻留在 CELL A3中; UE B3由于只支持功能 1但并不支持功能 2, 因此 UE B3将使用小区选 择重选参数 3 , 认为 CELL B3及 CELL C3所在频点拥有更高的优先级并将 比较 CELL B3及 CELL C3的测量结果来选择驻留小区, 并在比较时考虑 q-OffsetCell。 由于 UE B3 对 CELL B3及 CELL C3的测量结果相同, 可知 CELL B3 测量结果 +18db 大于 CELL C3 测量结果 (由于没有配置 q-OffsetCell for cellC, 因此不加 q-OffsetCell ), 因此终端 B3选择 CELL B3 驻留。
UE C3由于不支持功能 1和功能 2,因此 UE C3将选择没有 bitmap的小 区选择重选参数,认为 CELL B3和 CELL C3所在频点拥有更高的优先级并 将比较 CELL B3和 CELL C3的测量结果来选择驻留小区,并在比较时考虑 q-OffsetCell。 由于 UE B3 对 CELL B3和 CELL C3的测量结果相同, 可知 CELL B3测量结果 -2db 小于 CELL C测量结果 +18db, 因此 UE C3选择 CELL C3驻留。
小区选择重选参数 2和 3 中除了频点优先级和小区偏移外, 对于至少 一个或全部载频 和 /或 至少一个或全部小区, 针对不同 UE能力还可以分 别配置以下参数中的至少一个或全部:
最低接收 RSRP 门限 ( Q-RxLevMin )、 最低接收 RSRQ 门限 ( Q-QualMin ) 、 更高优先级选择门限(threshX-High )、更低优先级选择 门限( threshX-Low )、 速度状态因子( SpeedStateScaleFactors )、 禁止接入小 区 ( BlackCellList )及针对频点的 offset ( q-OffsetFreq )。
其中, 小区选择重选参数 2和 3 中没有出现的参数, 终端可选用小区 选择重选参数 1中对应参数的取值。
