200810067046.X,发明名称为"传输时间间隔的调整方法和装置"的中国专利 申请的优先权, 其全部内容通过引用结合在本申请中。
技术领域
本发明实施例涉及移动通信领域,尤指高速上行分组接入信道的传输时 间间隔调整技术。
背景技术
第三代合作伙伴计划 ( 3rd Generation Partnership Project, 简称" 3GPP" ) 的 R6版本引入了高速上行分组接入(High Speed Uplink Packet Access, 简称 "HSUPA") , 可以实现上行的高速数据传输。 其主要特点之一就是空口采 用传输时间间隔 (Transmission Timing Interval, 简称" ΤΤΓ) 为 10ms或 2ms 的短帧。 当业务承载在 HSUPA信道上时, 将 HSUPA信道的 TTI配置为 2ms可 以比将 ΤΉ配置为 10ms的情况提供更高的上行峰值速率。
在现有的方案中, 当业务承载在 HSUPA信道上时, 其 ΤΉ配置是固定 的, 一旦配置后就不会发生变化。也就是说要么一直就是 2ms, 要么是一直 就是 10ms。然而,发明人发现现有方案至少存在如下问题:固定配置 HSUPA 信道的 ΤΉ, 会造成基站的信道资源的浪费或影响业务的业务质量 QoS。 发明内容
本发明实施例解决的主要技术问题是提供了传输时间间隔的调整方法、
ΤΉ调整装置和无线网络控制器,可以根据当前 ΤΉ和业务实际流量动态调 整 HSUPA信道的 ΤΉ, 使得 ΤΉ既满足数据传输的需求, 同时也可以尽可 能地提高基站信道资源的利用率。
本发明实施例提供了一种传输时间间隔 ΤΉ的调整方法, 主要包括: 获取高速上行分组接入 HSUPA信道的当前业务流量; 比较所述获取的当前业务流量与预设的门限的大小关系; 根据当前传输时间间隔 ΤΉ及所述比较结果调整所述 HSUPA信道的 本发明实施例还提供了一种 ΤΉ调整装置, 主要包括:

本发明一实施例提供了一种传输时间间隔 ΤΉ的调整方法, 如图 1所示, 该方法主要包括:
S 101, 获取高速上行分组接入 HSUPA信道的当前业务流量。
其中, HSUPA信道的当前业务流量可以用单位时间内正确接收的业务 量表示。例如, 预先设置一个测量周期, 并获取在该测量周期内正确接收的 业务量, 则 HSUPA信道的当前业务流量可表示为在该测量周期内正确接收 的业务量与该预设测量周期的商: HSUPA信道当前业务流量 =测量周期内正 确接收的业务量 /测量周期。
S102, 比较获取的当前业务流量与预设的门限的大小关系。
此外, 该预设的门限可以是一个门限值也可以是两个不同的门限值。为 了避免产生乒乓现象, 可以根据当前的 ΤΉ而采用不同的门限值进行比较。 例如: 如果 HSUPA信道当前的 ΤΉ是 2ms, 可采用第一门限进行比较; 如果 HSUPA信道当前的 ΤΉ是 10ms,则可采用第二门限进行比较。该第一门限和 第二门限的具体取值可以根据实际的需要设置。一般情况下,第一门限值小 于第二门限值。
S103, 根据当前传输时间间隔 ΤΉ和比较结果调整 HSUPA信道的 ΤΉ。 如果 HSUPA信道当前的 ΤΉ是 2ms, 并且当前业务流量小于第一门限, 则将 HSUPA信道的 TTI调整为 10ms;如果 HSUPA信道当前的 TTI是 10ms, 并 且当前业务流量大于所述第二门限, 则可将 HSUPA信道的 ΤΉ调整为 2ms。
由此可以看出, 本发明实施例提供的 ΤΉ的调整方法, 根据当前的 ΤΉ 和 HSUPA当前业务流量对 ΤΉ进行调整, 从而可以根据业务实际流量动态 调整 HSUPA信道的 ΤΉ, 使得 ΤΉ既满足数据传输的需求, 同时也可以尽 可能地提高基站信道资源的利用率。
HSUPA信道的当前业务流量一般是由层二来获取, 而比较获取的当前 业务流量与预设的门限的大小关系可以由层二或者层三来完成,根据当前传 输时间间隔 ΤΉ和比较结果调整所述 HSUPA信道的 ΤΉ一般是由层三来完 成, 下面将对各种情况进行详细描述。
本发明一实施例提供了一种 ΤΉ的调整方法, 如图 2所示, 该方法可以 包括:
S201 , 获取 HSUPA信道的当前业务流量。
例如,预先设置一个测量周期, 并获取在该测量周期内正确接收的业务 量, 则 HSUPA信道的当前业务流量为在该测量周期内正确接收的业务量与 测量周期的商: HSUPA信道当前业务流量 =测量周期内正确接收的业务量 / 测量周期。
S202, 比较获取的当前业务流量与预设的门限的大小关系。
该预设的门限可以是一个门限值也可以是两个不同的门限值。为了避免 产生乒乓现象, 可以根据当前的 ΤΉ而采用不同的门限值进行判断。 例如: 如果 HSUPA信道当前的 ΤΉ是 2ms,采用第一门限进行比较;如果 HSUPA 信道当前的 ΤΉ是 10ms, 则采用第二门限进行比较。 而第一门限和第二门 限的具体取值可以根据实际的需要设置,一般情况下,第一门限值小于第二 门限值。
由于 HSUPA信道当前的 ΤΉ不同时, 采用的门限值可以是不同的, 那 么其比较的过程也有所不同。 例如, 如果 HSUPA信道当前的 ΤΉ为 2ms, 则判断当前业务流量是否小于第一门限, 而如果 HSUPA信道当前的 ΤΉ为 10ms, 则判断当前业务流量是否大于第二门限。
上述的比较过程可以由层二的无线链路控制 RLC实体或者媒介接入控 制 MAC实体来完成。
S203, 生成第一测量报告。
当比较结果为当前业务流量小于第一门限(当前 ΤΉ为 2ms)或当前业 务流量大于第二门限 (当前 ΤΉ为 10ms) 时, 可以根据该比较结果生成第 一测量报告,并由层二上报给层三。该第一测量报告的内容可以为当前业务 流量与预设流量门限的比较结果本身;也可以为触发信息,用于触发层三调 整 ΤΉ。 其中该触发信息为根据该比较结果生成的, 用于触发层三进行 ΤΉ 调整的信息。
S204, 对 ΤΉ进行调整。
层三在收到层二上报的第一测量报告后, 对 ΤΉ进行调整。例如, 如果
HSUPA信道当前的 ΤΉ是 2ms, 并且当前业务流量小于第一门限, 则将 HSUPA信道的 TTI调整为 10ms; 而如果 HSUPA信道当前的 TTI是 10ms, 并且当前业务流量大于第二门限, 则将 HSUPA信道的 ΤΉ调整为 2ms。
进一步地, 可以通过无线承载 RB重配置消息对 HSUPA信道的 ΤΉ进 行调整, 也就是层三根据层二的第一测量报告发送无线承载 RB重配置消息 对 HSUPA信道的 TTI进行调整。
本发明另一实施例还提供了一种 ΤΉ的调整方法, 如图 3所示, 该方法 可以包括:
S301 , 获取 HSUPA信道的当前业务流量。
S302, 比较获取的当前业务流量与预设的门限的大小关系。
其中, S301-S302的过程与 S201-S202中的相应描述基本一致, 此处不 再赘述。
S303, 在预设的第一触发周期内, 判断比较结果是否保持不变, 如果是 执行 S304, 如果否, 不对当前 ΤΉ进行调整。
进一步地,为了进一步提高比较结果的准确性,可以在比较结果为当前 业务流量小于第一门限(当前 ΤΉ为 2ms)或当前业务流量大于第二门限(当 前 ΤΉ为 10ms) 时, 不立即调整 ΤΉ, 而是等待一段时间, 在这段时间内 继续按照上述方法获取 HSUPA信道的当前业务流量和比较获取的当前业务 流量与预设的门限的大小关系,可以将该等待的时间称为第一触发周期, 该 第一触发周期长度大于或等于测量周期,例如,可以设置为测量周期的整数 倍。 如果当前的 ΤΉ为 2ms, S302中比较结果为当前业务流量小于第一门 限, 则在预设的第一触发周期内, 继续执行 S301-S302, 并判断比较结果是 否保持不变, 如果是, 执行 S304, 如果否, 不对当前 ΤΉ进行调整;
如果当前的 ΤΉ为 10ms, S302中比较结果为当前业务流量大于第二门 限, 则在预设的第一触发周期内, 继续执行 S301-S302, 并判断比较结果是 否保持不变, 如果是, 执行 S304, 如果否, 不对当前 ΤΉ进行调整。
5304, 生成第一测量报告。
此处生成第一测量报告的过程和方式和 S203基本相同,此处不再赘述。
5305, 对 ΤΉ进行调整。
此处对 ΤΉ进行调整的过程和方式和 S204基本相同, 此处不再赘述。 由于在对 ΤΉ进行调整时, 可能会导致业务流量的改变, 为了避免 ΤΉ 调整过程中流量测量的不准确而导致的误报,本发明实施例还提供了另一种 ΤΉ的调整方法, 如图 4所示, 该方法可以包括:
S401 , 获取 HSUPA信道的当前业务流量。
S402, 比较获取的当前业务流量与预设的门限的大小关系。
5403, 在预设的第一触发周期内, 判断比较结果是否保持不变, 如果是 执行 S404, 如果否, 不对当前 ΤΉ进行调整。
5404, 生成第一测量报告。
5405, 对 ΤΉ进行调整。
其中, S401-S405的过程与 S301-S305的相应描述基本一致, 此处不再 赘述。
5406, 在预设的挂起周期到达后, 重复 S401-S405。
也就是说,在对 ΤΉ进行调整后,等待一段时间再进行获取当前业务流 量及其后续步骤。此处, 可以将该等待的时间称为挂起周期。在该预设的挂 起周期内,停止当前业务流量的获取以及后续步骤, 当该预设的挂起周期到 达后, 重复执行 S401-S405。 另外, 需要说明的是, 上述实施例中的预设的第一门限、第二门限、 测 量周期、 第一触发周期以及挂起周期等参数可以在业务建立时预先配置好。
由此可以看出, 上述图 2-图 4所描述的实施例提供的 ΤΉ的调整方法, 可以根据当前的 ΤΉ和 HSUPA当前业务流量对 ΤΉ进行调整, 从而可以根 据业务实际流量动态调整 HSUPA信道的 ΤΉ, 使得 ΤΉ既满足数据传输的 需求, 同时也可以尽可能地提高基站信道资源的利用率。
上述图 2-图 4所描述的实施例中的 ΤΉ调整方法, 由层二获取 HSUPA 当前业务流量, 并由层二将该当前业务流量与预设的门限比较,而将该当前 业务流量与预设的门限比较的过程也可以由层三完成,本发明一实施例提供 了另一种 ΤΉ的调整方法, 如图 5所示, 该方法可以包括:
5501 , 层二获取 HSUPA信道的当前业务流量。
HSUPA信道的当前业务流量可以表示为单位时间内正确接收的业务 量。例如, 预先设置一个测量周期, 并获取在该测量周期内正确接收的业务 量, 则 HSUPA信道的当前业务流量可表示为在该测量周期内正确接收的业 务量与测量周期的商: HSUPA信道当前业务流量 =测量周期内正确接收的业 务量 /测量周期。 该获取当前业务流量的过程可以由层二的 RLC或者 MAC 实体完成。
5502, 将获取的当前业务流量上报给层三。
在层二获取了 HSUPA信道的当前业务流量, 将获取的当前业务流量上 报给层三。可以在测量周期到达时直接将获取的 HSUPA信道当前业务流量 上报, 也可以在预设的上报周期到达时, 再将获取的 HSUPA信道当前业务 流量上报。该上报周期大于或等于一个测量周期,一般情况下为测量周期的 整数倍。
5503, 比较当前业务流量与预设的门限的大小关系。
该比较过程可以由层三 (如无线资源控制 RRC实体) 完成, 层三根据 层二的上报获取到 HSUPA信道的当前业务流量后, 比较获取的当前业务流 量与预设的门限的大小关系。
由于 HSUPA信道当前的 ΤΉ不同时, 采用的门限值可以是不同的, 那 么其判断的过程也有所不同。 例如, 如果 HSUPA信道当前的 ΤΉ为 2ms, 则判断当前业务流量是否小于第一门限, 而如果 HSUPA信道当前的 ΤΉ为 10ms, 则判断当前业务流量是否大于第二门限。
S504, 对 ΤΉ进行调整。
如果 HSUPA信道当前的 ΤΉ是 2ms, 并且当前业务流量小于第一门限, 则将 HSUPA信道的 TTI调整为 10ms; 如果 HSUPA信道当前的 TTI是 10ms, 并 且当前业务流量大于所述第二门限, 则可将 HSUPA信道的 ΤΉ调整为 2ms。
进一步地, 可以通过无线承载 RB重配置消息对 HSUPA信道的 ΤΉ进 行调整, 也就是层三发送无线承载 RB重配置消息对 HSUPA信道的 ΤΉ进 行调整。
为了进一步提高比较结果的准确性, 可以在 S503中的比较结果为当前 业务流量小于第一门限(当前 ΤΉ为 2ms)或当前业务流量大于第二门限(当 前 ΤΉ为 10ms) 时, 不立即上报, 而是在预设的第二触发周期内, 判断比 较结果是否保持不变。 下面将结合实施例具体说明。
本发明实施例提供了另一种 ΤΉ的调整方法, 如图 6所示, 该方法可以 包括:
S601 , 层二获取 HSUPA信道的当前业务流量。
S602, 将获取的当前业务流量上报给层三。
5603, 比较当前业务流量与预设的门限的大小关系。
其中, S601-S603的过程与 S501-S503中的相应描述基本一致, 此处不 再赘述。
5604, 在预设的第二触发周期内, 判断比较结果是否保持不变, 如果是 执行 S605, 如果否, 不对当前 ΤΉ进行调整。
可以在 S603中的比较结果为当前业务流量小于第一门限 (当前 ΤΉ为 2ms)或当前业务流量大于第二门限(当前 ΤΉ为 10ms) 时, 不立即对 TTI 进行调整, 而是在预设的第二触发周期内, 判断比较结果是否保持不变。
在没有设置上报周期的情况下,该第二触发周期大于或等于一个测量周 期, 一般情况下为测量周期的整数倍; 在设置了上报周期的情况下, 该第二 触发周期大于或等于该上报周期, 例如, 可以设置为该上报周期的整数倍。
S605, 对 ΤΉ进行调整。
此处对 ΤΉ的调整过程与 S504中的描述基本一致, 此处不再赘述。 由于在对 ΤΉ进行调整时, 可能会导致业务流量的改变, 为了避免 ΤΉ 调整过程中流量测量的不准确而导致的误报,本发明实施例还提供了另一种 ΤΉ的调整方法, 如图 7所示, 该方法可以包括:
5701 , 层二获取 HSUPA信道的当前业务流量。
5702, 将获取的当前业务流量上报给层三。
S703, 比较当前业务流量与预设的门限的大小关系。
5704, 在预设的第二触发周期内, 判断比较结果是否保持不变, 如果是 执行 S705, 如果否, 不对当前 ΤΉ进行调整。
5705, 对 ΤΉ进行调整。
其中, S701-S705的过程与 S501-S503中的相应描述基本一致, 此处不 再赘述。
5706, 在预设的挂起周期到达后, 重复 S701-S705。
也就是说,在对 ΤΉ进行调整后,等待一段时间再进行获取当前业务流 量及其后续步骤。此处, 可以将该等待的时间称为挂起周期。在该预设的挂 起周期内,停止当前业务流量的获取以及后续步骤, 当该预设的挂起周期到 达后, 重复执行 S701-S705。
需要说明的是, 图 5-图 7所描述的实施例中的预设的第一门限、第二门 限、测量周期、上报周期、第二触发周期以及挂起周期等参数可以在业务建 立时预先配置好。 由此可以看出, 本发明实施例提供的 ΤΉ的调整方法, 根据当前 ΤΉ 和 HSUPA当前业务流量对 ΤΉ进行调整, 从而可以根据业务实际流量动态 调整 HSUPA信道的 ΤΉ, 使得 ΤΉ既满足数据传输的需求, 同时也可以尽 可能地提高基站信道资源的利用率。
本发明一实施例提供了一种 ΤΉ调整装置, 如图 8所示, 该 ΤΉ调整装 置可以包括:
获取单元 801, 用于获取 HSUPA信道的当前业务流量, 具体获取的过 程可以参照前述方法实施中的相关描述。
比较单元 802, 用于比较获取单元 801获取的当前业务流量与预设的门 限的大小关系。
其中, 该预设的门限可以是一个门限值也可以是两个不同的门限值。而 为了避免产生乒乓现象, 可以根据当前的 ΤΉ而采用不同的门限值进行判 断。 例如: 如果 HSUPA信道当前的 ΤΉ是 2ms, 采用第一门限进行比较; 如果 HSUPA信道当前的 ΤΉ是 10ms, 则采用第二门限进行比较, 而第一 门限和第二门限的具体取值可以根据实际的需要设置,一般情况下,第一门 限值小于第二门限值。
由于 HSUPA信道当前的 ΤΉ不同时, 采用的门限值可以是不同的, 那 么其比较的过程也有所不同。 例如, 如果 HSUPA信道当前的 ΤΉ为 2ms, 则判断当前业务流量是否小于第一门限, 而如果 HSUPA信道当前的 ΤΉ为 10ms, 则判断当前业务流量是否大于第二门限。
无线资源控制实体 803, 用于根据当前 ΤΉ以及比较单元 802的比较结 果调整 HSUPA信道的 ΤΉ。
如果 HSUPA信道当前的 ΤΉ是 2ms, 并且当前业务流量小于第一门限, 则将 HSUPA信道的 TTI调整为 10ms; 如果 HSUPA信道当前的 TTI是 10ms, 并 且当前业务流量大于所述第二门限, 则可将 HSUPA信道的 ΤΉ调整为 2ms。 该无线资源控制实体可以通过 RB重配置消息对 HSUPA信道的 ΤΉ进 行调整。
进一步地,为了提高比较结果的准确性,本发明实施例还提供了另一种 ΤΉ调整装置, 如图 9所示, 该 ΤΉ调整装置可以包括:
获取单元 901, 用于获取 HSUPA信道的当前业务流量, 具体获取的过 程可以参照前述方法实施中的相关描述。
比较单元 902, 用于比较获取单元 401获取的当前业务流量与预设的门 限的大小关系, 其比较过程可以参考上述方法实施例中的相应描述。
第一报告单元 903, 用于根据比较单元 902的比较结果生成第一测量报 告。
该第一测量报告的内容可以为当前业务流量与预设流量门限的比较结 果本身; 也可以为触发信息, 用于触发调整 ΤΉ。
无线资源控制实体 904, 用于根据当前 ΤΉ以及第一报告单元 903生成 的的第一测量报告调整 HSUPA信道的 ΤΉ。 该调整 ΤΉ的过程可参考上述 方法实施例中的相关描述。
进一步地, 为了提高比较结果的准确性, 该 ΤΉ调整装置还可以包括: 第一触发单元 905, 用于在预设的第一触发周期内, 判断比较单元 902 的比较结果是否保持不变, 如果是触发第一报告单元 903根据比较单元 902 的比较结果生成第一测量报告。
此外, 由于在对 ΤΉ进行调整时, 可能会导致业务流量的改变, 为了避 免 ΤΉ调整过程中流量测量的不准确而导致的误报,该 ΤΉ调整装置还可以 包括: 挂起单元 906, 用于在预设的挂起周期到达后, 通知获取单元 901 继续获取当前业务流量。也就是说, 在该预设的挂起周期内, 停止当前业务 流量的获取以及后续步骤, 当挂起周期到达时,重复当前业务流量的获取以 及后续步骤。 需要说明的是, 本实施例中的预设的第一门限、 第二门限、 测量周期、 第一触发周期以及挂起周期等参数可以在业务建立时由无线资源控制实体 预先配置好。
本发明实施例还提供了一种 ΤΉ调整装置, 如图 10所示, 该 ΤΉ调整 装置可以包括:

无线资源控制实体 1004, 用于根据当前 ΤΉ以及比较单元 1003的比较 结果, 调整 HSUPA信道的 ΤΉ。 该调整 ΤΉ的过程可参考上述方法实施例 中的相关描述。
其中,第二报告单元 1002可以在测量周期到达时直接将获取的 HSUPA 信道当前业务流量上报,也可以在预设的上报周期到达时,那么该第二报告 单元还可以包括:
上报控制子单元 10021, 在预设的上报周期到达时, 通知第二报告单元 1002将获取的 HSUPA信道当前业务流量上报。该上报周期大于或等于一个 测量周期, 一般情况下为测量周期的整数倍。
进一步地, 为了提高比较结果的准确性, 该 ΤΉ调整装置还可以包括: 第二触发单元 1005,用于在预设的第二触发周期内,判断比较单元 1003 的比较结果是否保持不变, 如果是, 则触发无线资源控制实体 1004对 ΤΉ 进行调整,如果否,不对当前 ΤΉ进行调整。在没有设置上报周期的情况下, 该第二触发周期大于或等于一个测量周期, 一般情况下为测量周期的整数 倍; 在设置了上报周期的情况下, 该第二触发周期大于或等于该上报周期, 例如, 可以设置为该上报周期的整数倍。
由于在对 ΤΉ进行调整时, 可能会导致业务流量的改变, 为了避免 ΤΉ 调整过程中流量测量的不准确而导致的误报, 该 ΤΉ调整装置还可以包括: 挂起单元 1006, 在预设的挂起周期到达后, 通知获取单元 1001继续获 取当前业务流量。也就是说, 在该预设的挂起周期内, 停止当前业务流量的 获取以及后续步骤。
