Description

一种信息处理方法、 用户设备以及基站
技术领域
本发明涉及通信领域, 特别涉及一种信息处理方法、 用户设备以及基站。 背景技术
随着科技的发展, 通信技术也得到了快速的发展, 从而为人们的生活带 来了更多的便利。
例如, 以物联网为例, 物联网是指通过部署具有一定感知、 计算、 执行 和通信能力的用户设备(UE, User Equipment ), 获取物理世界的信息, 通过 基站将信息发送到网络中, 继而实现信息传输、 协同和处理, 从而实现人与 物、 物与物的互联的网络, 使得物联网可以应用在智能电网、 智能农业、 智 能交通、 以及环境检测等各个方面, 为人们的生活提供各种便利。
由于用户设备本身硬件和软件的构成各不相同, 其所处的环境也各不相 同, 与基站进行通信时的通信状况也千差万别, 具体来讲, 不同的用户设备 在同一环境下与基站的通信状况可能会不相同, 而同一设备在不同的环境下 与基站的通信状况可能也会不相同。
目前, 为了保证用户设备与基站之间的准确通信, 通常是基站增加额的 通信资源, 比如, 对所传输的信息进行重复传输等, 以保证该基站和与该基 站进行通信的用户设备之间的通信准确性, 但是, 基站在增加额外的通信资 源时, 必须要保证该基站和与该基站进行通信时通信状况最差的用户设备之 间的通信准确性, 但针对其他通信状况较好的用户设备而言, 基站所增加的 额外的通信资源就造成了资源浪费。

在具体实施过程中, 覆盖增强需求可以是精度较低的第一覆盖增强需求, 也可以是精度较高的第二覆盖增强需求, 以覆盖增强为 0db-15db之间的分级 为例,请参考图 3A和图 3B, 图 3A是本发明实施例提供的第一覆盖增强需求 的分级示意图, 图 3B 是本发明实施例提供的第二覆盖增强需求的分级示意 图。
如图 3A所示, 第一覆盖增强需求的分类为: 路径损耗 5dB, 为覆盖增 强等级 LevelO; 5dB<路径损耗 10dB ,为覆盖增强等级 Levell ;路径损耗> 10dB , 为覆盖增强等级 Level2。 以覆盖增强技术为信号重复技术为例, LevelO 对应的信号重复次数可以是 5次, Levell对应的信号重复次数可以是 10次, Level2对应的信号重复次数可以是 15次。
如图 3B所示, 第二覆盖增强需求的分类为: 路径损耗 ldB, 为覆盖增 强等级 LevelO.l ; 1(18<路径损耗 2dB , 为覆盖增强等级 Level0.2; 2(18<路径 损耗 3dB , 为覆盖增强等级 Level0.3; 3dB ~径损耗 4dB, 为覆盖增强等 级 Level0.4; 4(18<路径损耗 5dB , 为覆盖增强等级 Level0.5; ··· ···; 14dB< 路径损耗 15dB , 为覆盖增强等级 Level2.5。 以覆盖增强技术为信号重复技 术为例, LevelO.l对应的信号重复次数可以是 1次, Level0.2对应的信号重复 次数可以是 2次, Level0.3对应的信号重复次数可以是 3次, Level0.4对应的 信号重复次数可以是 4次, Level0.5对应的信号重复次数可以是 5次, ……, Level2.5对应的信号重复次数可以是 15次。
通过第一覆盖增强需求中各个等级与第二覆盖增强需求中各个等级对应 的信号重复次数的对比可以看出, 由于第二覆盖增强需求划分等级的精度较 高, 所以如果覆盖增强需求使用第二覆盖增强需求的话, 可以使覆盖增强更 有针对性, 能够进一步减少资源的浪费。
但是, 如果在随机接入过程随机接入前导发送时就直接使用第二覆盖增 强需求的话, 会造成用户设备在随机接入过程中冲突概率过大的问题, 具体 来讲, 随机接入前导序列包括三类资源, 时域、 频域和码分。 以码分为例, 如果按照第一覆盖增强需求进行分级, 那么就需要把所有的码资源分成三份, 用户设备根据自己的测量结果选择合适的码资源发起随机接入过程, 基站通 过接收到的码, 判断用户设备属于哪一个覆盖增强需求等级, 若有两个用户 设备在随机接入过程中使用的码相同, 该两个用户的随机接入过程可能就会 被无效掉, 这就是随机接入过程中的冲突问题。 覆盖增强需求等级分的越细, 码资源被划分组的也越多, 每一个组中的码也会越少, 而该组中的码资源较 少, 这个组中的用户设备选择相同的码的概率也就越大, 被无效掉的用户设 备的随机接入过程也就越多, 从而这个组中的用户设备的随机接入过程冲突 概率也就越大。
在接下来的部分中, 将根据用户设备获得覆盖增强消息的两种方式, 来 具体介绍在不影响用户设备的随机接入过程中的冲突可能性的情况, 如何在 用户设备与基站进行通信使用第二覆盖增强需求, 来进一步减少资源浪费: 第一种方式: 用户设备通过获取基站的一些系统信号如基站一直下发的 下行参考信号, 来获得用户设备的覆盖增强需求。
用户设备在通过获取基站的一些系统信号, 获得用户设备的覆盖增强需 求之后, 还需要将该覆盖增强需求上报给基站, 使得基站确定用户设备当前 的覆盖增强需求。
需要说明的是,若此时上报的覆盖增强需求是如图 3A所示的第一覆盖增 强需求, 则直接上报即可, 若此时上报的覆盖增强需求是如图 3B所示的第二 覆盖增强需求, 则需要通过如下步骤进行上报:
在第一时刻, 用户设备在随机接入过程中向基站上报第一覆盖增强需求, 第一覆盖增强需求具有第一精度; 在第一时刻之后的第二时刻, 用户设备向 基站上报第一消息, 第一消息用于指示基站基于第一消息将第一覆盖增强需 求调整为第二覆盖增强需求, 第二覆盖增强需求具有第二精度, 第二精度高 于第一精度。
具体来讲, 可以是在第一时刻, 用户设备在发送随机接入前导序列的同 时, 向基站上 第一覆盖增强需求, 第一覆盖增强需求即可以是如图 3 所示 的第一覆盖增强需求, 该第一覆盖增强需求具有第一精度, 是以 5db为一级 为覆盖增强需求进行分类的。
在第一时刻之后的第二时刻, 用户设备向基站上报第一消息, 例如可以 是通过随机接入过程中的第三消息, 也即 Msg3向基站上报第一消息, 该第一 消息中包括了将第一覆盖增强需求调整为第二覆盖增强需求的指示信息, 当 然, 用户设备也可以通过其他新定义的专有消息向基站上报第一消息, 在此 不做限制。
在基站在第二时刻接收到该用户设备上报的第一消息后, 即可以将第一 覆盖增强需求调整为第二覆盖增强需求, 第二覆盖增强需求即可以是如图 3B 所示的第二覆盖增强需求, 该第二覆盖增强需求具有第二精度, 是以 ldb为 一级对覆盖增强需求进行分类的。
在实际应用中, 第一消息可以指示由第一覆盖增强需求调整至第二覆盖 增强需求的相对值, 也即第一消息是指示用户设备在第一覆盖增强需求上进 行调整而获得第二覆盖增强需求, 例如用户设备在第一时刻上报的第一覆盖 增强需求为 LevelO, 若第一消息指示覆盖增强需求等级 2, 则基站可以确定用 户设备的第二覆盖增强需求为 Level0.2; 当然, 第一消息也可以指示由第一覆 盖增强需求调整至第二覆盖增强需求的绝对值, 也即第一消息直接指示用户 设备的第二覆盖增强需求, 例如用户设备在第一时刻上报的第一覆盖增强需 求无论是 LevelO还是 Levell , 若第一消息指示覆盖增强需求等级 2, 则基站 可以确定用户设备的第二覆盖增强需求为 Level0.2。
通过上述部分可以看出, 用户设备在向基站上报第二覆盖增强需求之后, 使得基站能够确定用户设备的覆盖增强需求为比第一覆盖增强需求的第一精 度高的第二覆盖增强需求, 并根据第二覆盖增强需求与用户设备进行通信, 从而进一步减少资源浪费。
当然, 在用户设备向基站上报第二覆盖增强需求之后, 用户设备还可以 保存第二覆盖增强需求, 以供用户设备在下一次随机接入过程中使用, 例如 可以在下一次发送随机接入前导序列的时候使用, 当然了, 在实际应用中不 限制于此, 例如还可以在发送数据信道信号或者发送控制信道信号的时候使 用, 在此就不再赘述了。 可以看出, 由于采用了保存用户设备在与基站通信 所使用的覆盖增强需求, 以供用户设备在下一次随机接入过程中使用的技术 方案, 使得用户设备在下一次随机接入过程中能够快速而准确地获得用户设 备的覆盖增强需求, 从而进一步减少资源浪费。
第二种方式: 用户设备接收基站下发的覆盖增强需求指示消息, 来获得 用户设备的覆盖增强需求。
具体来讲, 可以是用户设备向基站上报消息, 使得基站能够根据用户设 备上报的消息生成覆盖增强需求指示消息, 并且将生成的覆盖增强需求指示 消息下发给用户设备, 用户设备即可以接收该覆盖增强需求指示消息, 从而 获得用户设备的覆盖增强需求, 此处的覆盖增强需求可以只是第一覆盖增强 需求, 也可以包括第二覆盖增强需求, 在此不做限制。
需要说明的是, 用户设备向基站上报的消息, 有可能包括一些特定的上 行参考消息, 这些消息只是供基站进行测量等使用, 而不会上报其他有用的 信息, 在此不做限制。
具体来讲, 可以是用户设备在第一时刻通过随机接入前导序列向基站上 报第一覆盖增强需求, 第一覆盖增强需求具有第一精度, 第一覆盖增强需求 可以是如图 3A所示的第一覆盖增强需求,从而使得基站在第一时刻之后的第 二时刻, 根据用户设备在第一时刻与第二时刻之间上报的消息, 获得用户设 备的第二覆盖增强需求, 并生成用于指示用户设备将第一覆盖增强需求调整 为第二覆盖增强需求的覆盖增强需求指示消息, 第二覆盖增强需求具有第二 精度, 第二精度高于第一覆盖增强需求的第一精度, 第二覆盖增强需求可以 是如图 3B所示的第二覆盖增强需求。
当然, 在实际应用中, 用户设备也可以不上报第一覆盖增强需求, 只是 从第一时刻开始上报消息, 使得基站能够在第一时刻之后的第二时刻, 根据 用户设备在第一时刻与第二时刻之间上报的消息, 获得用户设备的第二覆盖 增强需求, 并生成覆盖增强需求指示消息, 该覆盖增强需求指示消息即能够 指示用户设备的覆盖增强需求为第二覆盖增强需求, 该第二覆盖增强需求可 以是如图 3B所示的第二覆盖增强需求。 需要说明的是, 基站在根据用户设备 上报的消息生成覆盖增强需求指示消息的时候, 可以不是根据第一时刻与第 二时刻之间上报的所有消息, 而只是根据其中的一部分消息, 即可以测量获 知用户设备需要的覆盖增强需求, 从而生成覆盖增强需求指示消息, 在此就 不再赘述了。
在具体实施过程中, 用户设备可以是接收基站通过随机接入响应消息 ( RAR, Random Access Response ) 下发的覆盖增强需求指示消息。 例如,请参考图 4, 图 4是本发明实施例提供的随机接入响应消息的格式 示意图,如图 4所示,每一个随机接入响应消息包括一个预留位( R, Reserved ); 请继续参考图 5 ,图 5为用于承载随机接入响应消息的媒体接入控制协议数据 单元(MAC PDU, Media Access Control Protocol Data Unit ) 包含一个媒体接 入控制帧头 (MAC header )和若干个随机接入响应消息, 一个媒体接入控制 帧头包括若干个如图 6A所示的媒体接入控制子头 (MAC subheader ), 图 6A 所示的媒体接入控制子头不包括预留信息位,最多再包括一个如图 6B所示的 媒体接入控制子头, 图 6B所属的媒体接入控制子头包括两个预留信息位。
请同时参考图 4、 图 5、 图 6A和图 6B , 如果一个媒体接入控制协议数据 单元包括 n个随机接入响应消息, 则整个媒体接入控制协议数据单元包括 M 个预留信息位, n M n+2, 其中 n为大于等于 1的整数, M为正整数。
在基站通过随机接入响应消息向用户设备传递覆盖增强需求时, 可以通 过如下两个方式:
方式一: 基于用户设备上报的第一覆盖增强需求, 基站下发覆盖增强需 求指示消息, 该覆盖增强需求指示消息可以是一个绝对值, 也即无论用户设 备上的第一覆盖增强等级为何值, 该覆盖增强需求指示消息直接指示用户设 备的第二覆盖增强需求,例如无论用户设备上报的第一覆盖增强需求是 LevelO 还是 Levell , 若基站下发的覆盖增强需求指示消息所指示的第二覆盖增强需 求等级为 5 , 则用户设备就会根据该覆盖增强需求确定覆盖增强等级是 Level0.5。
方式二: 基于用户设备上报的第一覆盖增强需求, 基站下发覆盖增强需 求指示消息, 该覆盖增强需求指示消息可以是一个相对值, 也即用户设备根 据上的第一覆盖增强等级为何值, 该覆盖增强需求指示消息直接指示用户设 备的第二覆盖增强需求, 例如用户上报的第一覆盖增强需求为 Levell , 基站 下发的覆盖增强需求指示消息为 -2 ,则用户设备根据第一增强覆盖需求与覆盖 增强需求指示消息, 可以确定自己覆盖增强需求等级是 levell 的基础上减两 个等级为 level0.4; 基站下发等级 2, 终端就认为其覆盖增强等级是 levell的 基础上加两个等级为 levell.2; 在该方式下, 一个比特的信息位, 可以指示两 个二级相对值。, 比如, 0指示覆盖增强等级加(减)一级, 1 指示覆盖增强 等级加 (减) 两级; 也可以指示覆盖增强等级调整方向, 比如, 如果基站下 发 0, 终端就认为其覆盖增强等级需要下调一个等级, 如果下发 1 , 终端就认 为其覆盖增强等级需要上调一个等级。
在具体实施过程中,如果一个媒体接入控制帧头不包括一个如图 6B所示 的媒体接入控制子头, 则整个媒体接入控制协议数据单元包括 n个预留信息 位, 最少有 1个预留信息位可以使用, 若该媒体接入控制协议数据单元包括 1 个预留信息位, 则可以通过前述所介绍的方式一或方式二来向用户设备传递 覆盖增强需求, 若该媒体接入控制协议数据单元包括 n个随机接入响应消息, 则包括 n个预留信息位, 无论这 n个随机接入响应消息对应的用户设备的覆 盖增强需求是否一样, 都可以将这 n个预留信息位联合起来使用, 如两个预 留信息位可以指示 4个第二覆盖增强需求等级的相对值或者绝对值, 或者其 中一个预留信息位指示相对值的调整方向, 另外一个预留信息位用来指示调 整值, 预留信息位更多的情况就不再赘述了, 从而向用户设备传递覆盖增强 需求。
在具体实施过程中,如果一个媒体接入控制帧头包括一个如图 6A所示的 媒体接入控制子头, 则整个媒体接入控制协议数据单元包括 n+2个预留信息 位, 最少有 3个预留信息位可以使用, 则可以通过至少 3个预留信息位联合 起来使用, 具体过程与上述过程一样, 在此就不再赘述了, 从而向用户设备 传递覆盖增强需求。
当然, 除了上述通过随机接入响应消息的预留信息位来向用户设备传递 覆盖增强需求之外, 还可以通过随机接入响应消息的新增信息位来向用户设 备传递覆盖增强需求。
可以看出, 基站将覆盖增强需求指示消息添加在随机接入响应消息并下 发给用户设备, 从而向用户设备传递第二覆盖增强需求是完全没有问题的, 用户设备在接收基站通过随机接入响应消息下发的覆盖增强需求指示消息 后, 即能够根据该覆盖增强需求指示消息, 获得覆盖增强需求。
在具体实施过程中, 在用户设备根据基站下发的随机接入响应消息下发 的覆盖增强需求指示消息, 获得覆盖增强需求之后, 用户设备还可以保存该 覆盖增强需求, 这儿可以是第一覆盖增强需求, 也可以是第二覆盖增强需求, 在此不做限制, 从而方便用户设备在下一次随机接入过程中使用, 例如可以 供用户设备在下一次发送随机接入前导序列的时候使用, 从而在用户设备下 一次随机接入过程中快速而准确地确定用户设备的覆盖增强需求。
在通过步骤 S1获得用户设备的覆盖增强需求之后, 本发明实施例提供的 信息处理方法进入步骤 S2, 即: 用户设备根据覆盖增强需求, 与基站进行通 信。
在步骤 S2中, 具体来讲, 若覆盖增强需求指示的是用户设备的覆盖增强 级别, 且用户设备与基站之间预先定义了不同的覆盖增强级别所使用的覆盖 增强技术, 则用户设备则根据该覆盖增强需求指示的覆盖增强级别, 通过对 应的覆盖增强技术与基站进行通信。 需要说明的是, 步骤 S2中的覆盖增强需 求可以是步骤 S1中介绍的第一覆盖增强需求, 也可以是第二覆盖增强需求, 在此不做限制。
例如, 若覆盖增强需求为第一等级, 则其可以指示该用户设备的覆盖增 强级别为第一等级, 并且用户设备与基站之间预先定义的在第一等级下, 所 使用的覆盖增强技术为信号重复技术, 则用户设备会按照该覆盖增强需求对 应的信号重复次数, 与基站进行通信。
信号重复技术可以是在频域资源上进行重复, 也即在同一时刻, 在频域 的多个资源上发送同一信号, 也可以是时域资源上进行重复, 也即在同一频 域资源上, 在不同的时刻 (可以是连续的时刻) 重复发送信号, 从而使得用 户设备能够与基站准确进行通信。
当然, 在实际应用中, 除了可以是信号重复技术之外, 覆盖增强技术还 可以包括放松需求技术、 功率语密度借用 (PSD boosting, Power Spectrum Density boosting )技术或功率借用 (PB , power boosting )技术等等, 放松需 求技术是指在用户设备随机接入过程不成功的情况下, 让用户设备多尝试几 次, 从而使得用户设备能够与基站准确进行通信; 功率谱密度借用技术例如 是指为用户设备分配了三个资源发送消息, 现在就用一个资源发送, 其他两 个资源空着, 这样把本来用来在三个资源上发送信息的功率, 集中到一个资 源上发送, 达到加大这一个资源上的发射功率, 从而使得用户设备能够与基 站准确进行通信; 功率借用技术例如是指基站本来要同时对用户设备 A和用 户设备 B发送信号, 现在不对用户设备 B发送信号了, 把本来发送给用户设 备的信号的功率叠加到发送给用户设备 A的信号的功率上, 加大发送给用户 设备 A的信号的发射功率, 从而使得用户设备能够与基站准确进行通信。 需 要说明的是, 本发明实施例中的覆盖增强技术不限于所介绍的几种技术, 还 可以是本领域所属的技术人员能够使用的其他技术。
也就是说, 针对同一用户设备而言, 该用户设备会根据所处环境的不同, 根据该环境下的覆盖增强需求对应的信号重复次数与基站准确进行通信, 针 对不同用户设备而言, 用户设备会根据自身的覆盖增强需求对应的信号重复 次数, 与基站准确进行通信。
在具体实施过程中, 为了保证用户设备与基站进行通信时的准确性, 如 果两个不同等级的覆盖增强需求需要通过信号重复技术获得不同的覆盖增强 补偿, 那么, 所述不同等级的覆盖增强需求对应的信号重复次数也需不同, 因此, 在覆盖增强需求为第一等级时, 覆盖增强需求对应的信号重复次数为 第一数值, 例如可以为 6; 在覆盖增强需求为高于第一等级的第二等级时, 第 二覆盖增强需求对应的信号重复次数为大于第一数值的第二数值, 例如为 7; 在覆盖增强需求为低于第一等级的第三等级时, 覆盖增强需求对应的信号重 复次数为小于第一数值的第三数值, 例如为 5。
可以看出, 由于采用了在覆盖增强需求为第一等级时, 覆盖增强需求对 应的信号重复次数为第一数值; 在覆盖增强需求为高于第一等级的第二等级 时, 第二覆盖增强需求对应的信号重复次数为大于第一数值的第二数值; 在 覆盖增强需求为低于第一等级的第三等级时, 覆盖增强需求对应的信号重复 次数为小于第一数值的第三数值的技术方案, 避免了两个不同等级的覆盖增 强需求对应的信号重复次数相同, 从而保证了用设备与基站进行通信时的准 确性。
在具体实施过程中, 若覆盖增强需求为某一指定等级的时候, 该用户设 备与基站之间的通信状况非常良好, 不需要通过信号重复技术来保证用户设 备与基站准确进行通信, 因此, 可以设置该指定等级的覆盖增强需求对应的 信号重复次数为 0, 在此就不再赘述了。
当然, 若覆盖增强需求为某个指定等级的时候, 该用户设备与基站之间 的通信状况不太良好, 需要使用覆盖增强技术来保证用户设备与基站准确进 行通信, 但是只需要通过前述介绍的覆盖增强技术中除信号重复技术之外的 其他技术与基站进行通信即可, 而不需要使用信号重复技术, 在此就不再赘 述了。 需要说明的是, 此处所介绍的某个指定等级与前述部分中信号重复次 数为 0对应的覆盖增强需求的指定等级可以相同, 也可以不相同, 在此不做 限制。
通过上述部分可以看出, 由于采用了用户设备获得覆盖增强需求, 并且 根据覆盖增强需求, 与基站进行通信的技术方案, 在保证了用户设备与基站 准确进行通信的情况下, 用户设备根据获得的覆盖增强需求与基站准确进行 通信, 避免了基站在与通信状况良好的用户设备进行通信时, 仍然增加与通 信状况较差的用户设备进行通信时同样多的通信资源的情况, 从而解决了现 有技术中在基站和用户设备进行通信时存在资源浪费的技术问题, 实现了减 少资源浪费的技术效果。
在具体实施过程中, 为了用户设备在下一次随机接入过程中, 能够快速 而准确地获得自己的覆盖增强需求, 保证与基站准确进行通信, 在用户设备 根据覆盖增强需求, 与基站进行通信之后, 本发明实施例提供的信息处理方 法还包括: 用户设备保存覆盖增强需求, 以供该用户设备在下一次随机接入 过程中使用。 需要说明的是, 这儿可以是第一覆盖增强需求, 也可以是第二 覆盖增强需求, 在此不做限制。 例如, 用户设备根据获得的覆盖增强需求, 与基站准确进行通信之后, 即保存该覆盖增强需求, 从而在用户设备下一次发起随机接入过程的时候直 接使用该覆盖增强需求即可, 例如在用户设备发起随机接入过程的时候, 通 过保存的覆盖增强需求上报随机接入前导序列, 从而保证用户设备与基站准 确进行通信。

1、 由于采用了用户设备获得覆盖增强需求, 并且根据覆盖增强需求, 与 基站进行通信的技术方案, 在保证了用户设备与基站准确进行通信的情况下, 用户设备根据获得的覆盖增强需求与基站准确进行通信, 避免了基站在与通 信状况良好的用户设备进行通信时, 仍然增加与通信状况较差的用户设备进 行通信时同样多的通信资源的情况, 从而解决了现有技术中在基站和用户设 备进行通信时存在资源浪费的技术问题, 实现了减少资源浪费的技术效果。

3、 由于采用了保存用户设备在与基站通信所使用的覆盖增强需求, 以供 用户设备在下一次随机接入过程中使用的技术方案, 使得用户设备在下一次 随机接入过程中能够快速而准确地获得用户设备的覆盖增强需求, 从而进一 步减少资源浪费。
4、 由于采用了在覆盖增强需求为第一等级时, 覆盖增强需求对应的信号 重复次数为第一数值; 在覆盖增强需求为高于第一等级的第二等级时, 第二 覆盖增强需求对应的信号重复次数为大于第一数值的第二数值; 在覆盖增强 需求为低于第一等级的第三等级时, 覆盖增强需求对应的信号重复次数为小 于第一数值的第三数值的技术方案, 避免了两个不同等级的覆盖增强需求对 应的信号重复次数相同, 从而保证了用设备与基站进行通信时的准确性。
本领域内的技术人员应明白, 本发明的实施例可提供为方法、 系统、 或 计算机程序产品。 因此, 本发明可采用完全硬件实施例、 完全软件实施例、 或结合软件和硬件方面的实施例的形式。 而且, 本发明可采用在一个或多个 其中包含有计算机可用程序代码的计算机可用存储介质 (包括但不限于磁盘 存储器、 CD-ROM、 光学存储器等)上实施的计算机程序产品的形式。

这些计算机程序指令也可存储在能引导计算机或其他可编程数据处理设 备以特定方式工作的计算机可读存储器中, 使得存储在该计算机可读存储器 中的指令产生包括指令装置的制造品, 该指令装置实现在流程图一个流程或 多个流程和 /或方框图一个方框或多个方框中指定的功能。
这些计算机程序指令也可装载到计算机或其他可编程数据处理设备上, 使得在计算机或其他可编程设备上执行一系列操作步骤以产生计算机实现的 处理, 从而在计算机或其他可编程设备上执行的指令提供用于实现在流程图 一个流程或多个流程和 /或方框图一个方框或多个方框中指定的功能的步 骤。
尽管已描述了本发明的优选实施例, 但本领域内的技术人员一旦得知了 基本创造性概念, 则可对这些实施例作出另外的变更和修改。 所以, 所附权 利要求意欲解释为包括优选实施例以及落入本发明范围的所有变更和修改。 脱离本发明实施例的精神和范围。 这样, 倘若本发明实施例的这些修改和变 型属于本发明权利要求及其等同技术的范围之内, 则本发明也意图包含这些 改动和变型在内。
