以下各实施例中所涉及的方法、 设备及系统可以适用于任意终端类型。 以下实施例中, 仅以终端类型包括窄带终端为例进行说明, 并不以此为 限。 实际应用中, 通知当前小区支持的终端类型可以是一种或一种以上, 仅 需网络侧与终端相互约定即可, 其具体实施可参照以下实施例进行。
之外, 还对覆盖增强有更高的要求, 还可以具有支持的编码调制方式的类型 更少、 支持编码调制方式更为简单、 对省电有着更高的要求等附加特点。
以下实施例中仅以通知当前小区支持窄带终端这一种终端类型为例进行 说明, 本发明实施例中, 可以通过指示信息通知当前小区支持的多种终端类 型, 其具体实施过程可参照仅通知一种终端类型的实施过程。
本发明第一实施例中, 如图 1 所示, 以基站为执行主体, 通知当前小区 支持窄带终端的网络侧实现的详细方法流程如下:
步骤 101 : 在下行信号中携带预设的指示信息, 该指示信息用于指示当前 小区支持的终端类型包括窄带终端, 该预设的指示信息由网络侧与终端预先 约定。
根据指示信息的不同, 可以有以下两种具体实施方式:
第一种具体实施方式中, 指示信息为同步序列, 即通过在同步信道中发 送预定的同步序列指示当前小区支持窄带终端。
第二种具体实施方式中, 指示信息是用于指示是否支持窄带终端的第一 指示位, 具体地, 携带该第一指示位的下行信号可以是系统消息或广播消息。
例如, 在广播信道设置 1 个比特(bit )位作为指示信息的第一指示位, 通过该广播信道发送的 MIB中, 与设置的 1个比特位对应的位置所携带的即 为指示当前小区是否支持窄带 UE的指示信息, 假设设置该比特位的值为 0, 则指示当前小区不支持窄带 UE, 设置该比特位的值为 1 , 则指示当前小区支 持窄带 UE。
针对第一种具体实施方式, 在下行信号中携带的同步序列有以下两种具 体实施方式:
第一种, 通过对下行信号的组成进行改变, 将下行信号中的部分组成部 分替换为同步序列, 通过承载在已有的物理资源上发送;
第二种, 现有的下行信号的组成不变, 在该下行信号中任意位置或设定 位置增加该同步序列, 为该同步序列分配新的物理资源, 通过该同步序列承 载在该新的物理资源上发送。
其中, 同步序列占用的已有的物理资源或者新增的物理资源可以是时域 资源、 频域资源、 码域资源中的任意一种。
针对第一种具体实施方式, 在下行信号中携带预设的同步序列时, 根据 携带同步序列的位置, 可以有以下两种实现:
第一种, 在下行信号的设定位置携带该同步序列, 即固定同步序列在下 行信号中的位置;
第二种, 不固定同步序列在下行信号中的位置, 只需下行信号中携带该 同步序列即可。
步骤 102: 发送下行信号至终端。
较佳地, 根据网络侧的配置策略对窄带 UE进行相应的配置, 窄带 UE在 接收下行信号后 , 根据预先配置的策略检测该下行信号中是否携带指示信息 , 根据该指示信息确定当前小区支持窄带 UE。
具体实施中, 接收下行信号的可以是任意类型的终端, 即网络侧与任意 终端约定指示信息的含义, 使得任意类型的终端均可以接收该下行信号, 并 且可以根据该下行信号获知当前小区支持窄带 UE; 也可以是仅窄带 UE能够 成功接收该下行信号并解析, 即网络侧仅与窄带终端约定指示信息的含义, 使得非窄带 UE不能接收该下行信号, 或者是能够接收该下行信号,在解析失 败后再行丟弃。
本发明第二实施例中, 如图 2所示, 以窄带 UE为执行主体, 通知当前小 区支持窄带 UE的详细方法流程如下, 需要说明的是,此处仅以执行主体为窄 带 UE为例进行说明, 该实施例中, 执行主体可以是任意类型的 UE, 其可以 通过下述流程获知当前小区支持的终端类型:
步骤 201 : 接收当前小区发送的下行信号。
步骤 202: 根据该下行信号中携带预设的指示信息, 确定当前小区支持的 终端类型包括窄带终端, 预设的指示信息由网络侧与终端预先约定。
具体实施中,任意类型的 UE在确定当前小区支持的终端类型后,判断自 身的终端类型是否属于当前小区所支持的终端类型, 若属于则继续接入当前 小区, 否则, 选择其它小区进行接入。
具体地, 根据网络侧的配置, 预设的指示信息为同步序列或用于指示是 否支持窄带终端的第一指示位。
具体地, 根据网络侧的配置, 若同步序列固定设置于下行信号中的预定 位置, 则窄带 UE接收该下行信号后,确定该下行信号的预定位置携带有该同 步序列, 则确定当前小区支持的终端类型包括窄带 UE。
针对上述第一实施例和第二实施例, 进一步地, 若小区中存在的覆盖增 强的需求,在通知当前小区支持窄带 UE的同时,或在通知当前小区支持窄带 UE之后, 需要通知当前小区所能支持的覆盖增强等级, 具体地, 通知当前小 区所能支持的覆盖增强等级可以有以下几种实现方式:
第一种, 在网络侧预先配置小区的覆盖增强等级与同步序列的对应关系, 其中, 不同的覆盖增强等级与不同的同步序列——对应, 该对应关系可以是 预先配置在基站的当前小区, 也可以是配置在网络侧的其它网络设备上, 由 该网络设备将配置的针对当前小区的该对应关系发送给基站。
基站通过同步序列通知当前小区支持窄带 UE的同时,也通过该同步序列 通知当前小区所能够支持的覆盖增强等级, 具体为:
根据预先配置的对应关系在下行信号中携带同步序列的具体过程为: 根据预设的覆盖增强等级与同步序列的对应关系, 选择与当前小区能够 支持的覆盖增强等级所对应的同步序列, 该对应关系中不同的覆盖增强等级 与不同的同步序列——对应;
在下行信号中携带选择的同步序列。 相应地,在终端侧, 即窄带 UE上按照网络侧的配置策略预先配置小区的 覆盖增强等级与同步序列的对应关系, 其中, 不同的覆盖增强等级与不同的 同步序列——对应。该对应关系可以是网络侧设备发送给窄带 UE的,也可以 是预置在窄带 UE上的。
窄带 UE接收下行信号后, 确定当前小区支持窄带 UE的同时, 确定当前 小区的覆盖增强等级, 具体为:
根据预设的同步序列与覆盖增强等级的对应关系, 获取与下行信号中携 带的同步序列对应的覆盖增强等级, 该对应关系中不同的覆盖增强等级对应 不同的同步序列;
将获取的该覆盖增强等级确定为当前小区能够支持的覆盖增强等级。 例如, 在预设的配置信息中将同步序列划分为 3类(A、 B、 C类), 每类 同步序列对应不同的覆盖增强等级, 假设 A、 B、 C类同步序列对应的覆盖增 强等级递增, 则 UE在接收到的下行信号中携带的同步序列属于 A类时, 确 定当前小区支持的覆盖增强等级为 1倍重复; UE在接收到的下行信号中携带 的同步序列属于 B类时, 确定当前小区支持的覆盖增强等级为 1倍重复和 8 倍重复; UE在接收到的下行信号中携带的同步序列属于 C类时, 确定当前小 区支持的覆盖增强等级为 1倍重复、 8倍重复和 64倍重复。
第二种, 在网络侧预先配置小区的覆盖增强等级与同步序列占用的物理 资源的相关信息的对应关系, 不同的覆盖增强等级对应的物理资源的相关信 息不同, 该对应关系可以是预先配置在基站的当前小区, 也可以是配置在网 络侧的其它网络设备上, 由该网络设备将配置的针对当前小区的该对应关系 发送给基站。
通过同步序列通知当前小区支持窄带 UE的同时,也通过该同步序列通知 当前小区所能够支持的覆盖增强等级, 具体为:
根据预设的覆盖增强等级与同步序列占用的物理资源的相关信息的对应 关系, 选择与当前小区能够支持的覆盖增强等级相应的同步序列占用的物理 资源的相关信息, 该对应关系中不同的覆盖增强等级与不同的物理资源的相 关信息——对应;
根据选择的物理资源的相关信息确定物理资源, 并将该同步序列承载在 该物理资源上。
其中, 物理资源的相关信息至少包括物理资源的类型信息和位置信息, 即能够唯一确定物理资源的最少信息。
其中, 物理资源为时域资源、 频域资源或码域资源。
其中, 确定的物理资源可以是承载下行信号的原有物理资源中的一部分, 也可以是在承载下行信号的原有物理资源基础上新增的物理资源。
相应地,在终端侧, 即窄带 UE上按照网络侧的配置策略预先配置小区的 覆盖增强等级与同步序列占用的物理资源的相关信息的对应关系, 其中, 不 同的覆盖增强等级与不同的物理资源的相关信息——对应。 该对应关系可以 是网络侧设备发送给窄带 UE的, 也可以是预置在窄带 UE上的。
窄带 UE接收下行信号后, 确定当前小区支持窄带 UE的同时, 确定当前 小区的覆盖增强等级, 具体为:
确定下行信号中携带的同步序列所占用的物理资源的相关信息; 根据预设的覆盖增强等级与同步序列占用的物理资源的相关信息的对应 关系, 获取与确定的物理资源的相关信息对应的覆盖增强等级, 对应关系中 该不同的覆盖增强等级与不同的物理资源的相关信息——对应;
将获取的覆盖增强等级确定为当前小区所能够支持的覆盖增强等级。 具体实施中, 预先配置小区的覆盖增强等级与同步序列占用的物理资源 的相关信息的对应关系时, 也可以预设覆盖增强等级与同步序列的对应关系, 即不同的覆盖增强等级对应的同步序列不同, 对应的同步序列占用的物理资 源的相关信息也不相同。
例如, 对应覆盖增强等级 1 , 设置相应的同步序列属于同步序列集合 1 , 该同步序列占用的物理资源属于物理资源集合 1 ; 对应覆盖增强等级 1和 2, 设置相应的同步序列属于同步序列集合 2 ,该同步序列占用的物理资源属于物 理资源集合 2; 对应覆盖增强等级 1、 2和 3 , 设置相应的同步序列属于同步 序列集合 3 , 该同步序列占用的物理资源属于物理资源集合 3。
第三种, 在网络侧预先配置小区的覆盖增强等级与同步序列密度的对应 关系, 不同的覆盖增强等级对应不同的同步序列密度, 该对应关系可以是预 先配置在基站的当前小区, 也可以是配置在网络侧的其它网络设备上, 由该 网络设备将配置的针对当前小区的该对应关系发送给基站。
通过同步序列通知当前小区支持窄带 UE的同时,也通过该同步序列通知 当前小区所能够支持的覆盖增强等级, 具体为:
根据预设的同步序列密度与覆盖增强等级的对应关系, 选择与当前小区 能够支持的覆盖增强等级所对应的同步序列密度, 该对应关系中不同的覆盖 增强等级与不同的同步序列密度一一对应;
在下行信号中携带按照选择的同步序列密度排列的同步序列。
在一个优选的实施方式中, 可以设定覆盖增强等级越高对应的同步序列 密度越高。
相应地,在终端侧, 即窄带 UE上按照网络侧的配置策略预先配置小区的 覆盖增强等级与同步序列密度的对应关系, 其中, 不同的覆盖增强等级对应 不同的同步序列密度。该对应关系可以是网络侧设备发送给窄带 UE的,也可 以是预置在窄带 UE上的。
窄带 UE接收下行信号后, 确定当前小区支持窄带 UE的同时, 确定当前 小区的覆盖增强等级, 具体为:
确定下行信号中携带的同步序列的同步序列密度;
根据预设的同步序列密度与覆盖增强等级的对应关系, 获取与确定的同 步序列密度对应的覆盖增强等级, 该对应关系中不同的覆盖增强等级与不同 的同步序列密度——对应;
将获取的覆盖增强等级确定为当前小区所能够支持的覆盖增强等级。 第一种〜第三种实现方式中, 均是釆用同步序列指示当前小区支持窄带 UE, 同时釆用该同步序列指示当前小区所能够支持的覆盖增强等级。
以下提供的第四种、 第五种实现方式中, 可以是在下行信号中携带同步 序列通知当前小区支持窄带 UE, 也可以是在下行信号中携带第一指示位通知 当前小区支持窄带 UE, 再通过其它方式通知当前小区能够支持的覆盖增强等 级。
第四种, 在网络侧预先配置小区的覆盖增强等级与第二指示位的值的对 应关系, 不同的覆盖增强等级对应不同的第二指示位的值, 该对应关系可以 是预先配置在基站的当前小区, 也可以是配置在网络侧的其它网络设备上, 由该网络设备将配置的针对当前小区的该对应关系发送给基站。
在下行信号中携带预设的指示信息通知当前小区支持窄带 UE的同时,还 包括:
根据预设的覆盖增强等级与第二指示位的值的对应关系, 选择与当前小 区能够支持的覆盖增强等级对应的第二指示位的值, 该对应关系中不同的覆 盖增强等级与不同的第二指示位的值一一对应;
在下行信号中携带第二指示位, 且该第二指示位设为选择的第二指示位 的值。
相应地,在终端侧, 即窄带 UE上按照网络侧的配置策略预先配置小区的 覆盖增强等级与第二指示位的值的对应关系, 其中, 不同的覆盖增强等级与 不同的第二指示位的值——对应。 该对应关系可以是网络侧设备发送给窄带 UE的, 也可以是预置在窄带 UE上的。
窄带 UE接收下行信号后, 确定当前小区支持窄带 UE后, 确定当前小区 的覆盖增强等级, 具体为:
确定下行信号中携带第二指示位, 并获取第二指示位的值;
根据预设的覆盖增强等级与第二指示位的值的对应关系, 选择与获取的 第二指示位的值对应的覆盖增强等级, 该对应关系中不同的覆盖增强等级与 不同的第二指示位的值——对应;
将选择的覆盖增强等级确定为当前小区所能够支持的覆盖增强等级。 第五种, 在网络侧预先配置小区的覆盖增强等级与跳频方式的对应关系, 不同的覆盖增强等级对应不同的跳频方式, 该对应关系可以是预先配置在基 站的当前小区, 也可以是配置在网络侧的其它网络设备上, 由该网络设备将 配置的针对当前小区的该对应关系发送给基站。
在下行信号中携带预设的指示信息通知当前小区支持窄带 UE的同时,还 包括:
根据预设的覆盖增强等级与跳频方式的对应关系, 选择与前小区能够支 持的覆盖增强等级相应的跳频方式, 该对应关系中不同的覆盖增强等级与不 同的 ϋ频方式——对应;
按照选择的跳频方式生成该下行信号。
相应地,在终端侧, 即窄带 UE上按照网络侧的配置策略预先配置小区的 覆盖增强等级与跳频方式的对应关系, 其中, 不同的覆盖增强等级与不同的 跳频方式——对应。该对应关系可以是网络侧设备发送给窄带 UE的,也可以 是预置在窄带 UE上的。
窄带 UE接收下行信号后, 确定当前小区支持窄带 UE后, 确定当前小区 的覆盖增强等级, 具体为:
确定下行信号釆用的跳频方式;
根据预设的覆盖增强等级与跳频方式的对应关系, 获取与确定的跳频方 式对应的覆盖增强等级, 该对应关系中不同的覆盖增强等级与不同的跳频方 式——对应;
将获取的覆盖增强等级确定为当前小区所能够支持的覆盖增强等级。 优选地, 在第二实施例中, 终端侧在确定当前小区所能够支持的覆盖增 强等级后, 还包括:
确定下行信号的强度大小;
将下行信号的强度大小与预设的阔值进行比较, 确定窄带终端成功接入 当前小区需要当前小区支持的覆盖增强等级;
若确定的当前小区所能够支持的覆盖增强等级, 能够满足确定的需要当 前小区支持的覆盖增强等级, 接入该当前小区;
否则, 选择其他小区接入。 具体实施中, 终端侧将下行信号的强度大小与预设的阔值进行比较时, 预设的阔值的个数及大小根据覆盖增强等级的级数确定。
优选地, 预设的阔值的个数为覆盖增强等级的级数减一, 预设的各阔值 的大小为当前小区处于覆盖增强等级的临界状态时对应的下行信号的强度 值。
其中, 将下行信号的强度大小与预设的阔值进行比较, 具体为: 将下行信号的强度大小, 按照预设的各阔值的大小顺次与各阔值进行比 较, 确定该下行信号的强度大小所属的由各阔值划分的范围, 该范围所对应 的覆盖增强等级即为窄带终端成功接入当前小区需要当前小区支持的覆盖增 强等级。
以覆盖增强等级的级别为 3 为例, 预设的阔值为两个, 终端侧将下行信 号的强度大小与预设的阔值进行比较, 确定窄带终端成功接入当前小区需要 当前小区支持的覆盖增强等级的具体过程如下:
将下行信号的强度大小与预设的第一阔值和第二阔值进行比较; 若下行信号的强度大小不小于第一阔值, 确定窄带终端成功接入当前小 区需要当前小区支持第一覆盖增强等级;
若下行信号的强度大小大于等于第二阔值, 且小于第一阔值, 确定窄带 终端成功接入当前小区需要当前小区支持第二覆盖增强等级;
若所述下行信号的强度大小不大于第二阔值, 确定窄带终端成功接入当 前小区需要当前小区支持第三覆盖增强等级;
其中, 第一覆盖增强等级、 第二覆盖增强等级、 第三覆盖增强等级对应 的覆盖增强能力递增。
其中, 第一阔值为当前小区处于第一覆盖增强等级与第二覆盖增强等级 之间临界状态时下行信号的强度值, 第二阔值为当前小区处于第二覆盖增强 等级与第三覆盖增强等级之间的临界状态时下行信号的强度值。
其中, 下行信号的强度大小可以是根据参考信号接收功率、 同步信号的 功率确定, 此处仅为举例, 本发明并不以此为限。 例如, 假设将覆盖增强等级划分为 3级, 分别为覆盖增强等级 1、 覆盖增 强等级 2和覆盖增强等级 3 , 按照该次序覆盖增强能力递增, 预设的阔值为 P1和 P2, P1大于 P2, 具体判断过程如下:
当下行信号强度 P大于等于 P1时, 说明 UE接入当前小区需要当前小区 能够支持覆盖增强等级 1 ;
当下行信号强度 P大于等于 P2, 且小于 P1时,说明 UE接入当前小区需 要当前小区能支持覆盖增强等级 2;
当下行信号强度 P大于 p2时, 说明 UE接入当前小区需要当前小区能支 持覆盖增强等级 3;
根据判断结果,如果 UE接入当前小区需要当前小区能够支持覆盖增强等 级 3 , 而当前小区实际仅能够支持的覆盖增强等级 2, 则确定 UE无法接入当 前小区, 选择其它小区进行接入并驻留;
根据判断结果,如果 UE接入当前小区需要当前小区能够支持覆盖增强等 级 2, 而当前小区实际仅能够支持的覆盖增强等级 1 , 则确定 UE无法接入当 前小区, 选择其它小区进行接入并驻留;
根据判断结果,如果 UE接入当前小区需要当前小区能够支持覆盖增强等 级 1 , 而当前小区实际仅能够支持的覆盖增强等级 2, 则确定 UE能够接入当 前小区, 选择当前小区进行接入并驻留。
