Description

切换方法和设备 技术领域
本发明涉及通信领域, 尤其涉及通信领域中切换方法和设备。 背景技术
高速上行分组接入( high speed uplink packet access, 简称为 "HSUPA" ) 是第三代移动通信伙伴计戈' j ( 3rd Generation Partnership Proj ect, 筒称为 "3GPP" ) 的第 6版本(Release6, 简称为 "R6" ) 引入的技术, 该技术是上 行链路方向(从移动终端到无线接入网络的方向)针对分组业务的优化和演 进。 HSUPA利用自适应编码、 物理层混合重传、 基于基站 (Node B ) 的快 速调度和 2ms传输时间间隔( Transmission Time Interval, 简称为 "ΤΤΓ )短 帧传输等机制, 实现了在最高数据传输速率、 小区吞吐量以及延迟方面的增 强。
虽然 HSUPA引入 2ms TTI的传输方式能够进一步降低传输延迟, 但是 基于 2ms TTI 的短帧传输方式不适合用户设备 ( User Equipment, 简称为 "UE" )在小区的边缘工作, 因此降低了 UE在小区的覆盖范围。 特别是当 UE总发射功率达到了最大发射功率一段时间时,应进行 2ms TTI到 10ms TTI 的切换来增强上行覆盖范围, 具体流程如下:
( 1 ) 网络通过测量控制消息为 UE配置 6d事件;
( 2 )在 UE发射功率达到最大允许发射功率并持续一段时间后, UE将 向网络上报测量报告;
( 3 ) 无线网络控制器 (Radio Network Controller, 简称为 "RNC" ) 收 到此测量报告后, 判断该 UE上行发射功率是否已经功率受限, 并发送重配 置消息 (可包括无线承载重配置消息, 传输信道重配置消息等)给 UE进行 TTI长度的重配;
( 4 ) UE收到此重配消息后, 在网络侧给定的时间点执行该重配消息, 从而完成 2ms TTI到 10ms TTI的切换。
由于上述现有技术通过 UE上报 6d事件, 并且由 R C通过 6d事件判 断 UE功率受限, 再发起重配消息配置 UE进行 TTI切换, 因此, UE切换 到 10ms TTI的传输方式时延 4艮长。 发明内容
为此, 本发明实施例的主要目的是减少切换传输时间间隔的时延。 为了实现上述以及其他目的, 本发明实施例提供了一种切换方法。 所述 切换方法包括:

基于上述技术方案, 本发明实施例通过基站直接通知用户设备进行传输 时间间隔的切换,避免了基站通过无线网络控制器来通知用户设备进行传输 时间间隔的切换, 由此能够减少切换传输时间间隔的时延, 从而能够实现快 速地进行传输时间间隔的切换。 附图说明

其中, 用户设备(UE ) 包括但不限于移动电话、 便携式计算机、 个人 数字助理 (PDA )、 便携式游戏机和便携式多媒体机。
当 UE接收到基站要求 UE切换传输时间间隔的切换指示信息时, 例如 基站要求 UE从 2ms TTI切换到 10ms TTI时, UE根据接收到的切换指示信 息向基站发送对切换指示信息进行确认的切换确认信息, 以确认接收到该切 换指示信息并将进行传输时间间隔的切换, 随后 UE切换传输时间间隔, 如 从 2ms TTI切换到 10ms TTI。 由此, UE能够减少切换传输时间间隔的时延, 从而能够快速地进行传输时间间隔的切换。
在上述实施例的步骤 S110 中, 基站可通过下发高速共享控制信道命令 ( High-Speed Shared Control Channel order, 简称为 "HS-SCCH order" )或其 他合适的方式来承载切换指示信息。

当设置命令类型为 ^, ^, 。^= "001 " 时, 可以设置命令内容 χ。^ 或 x。 来承载指示信息,或同时设置命令内容 ^和 x。^2来承载指示信息。 当设置命令类型 为除了 "000" 和 "001 " 之外的任意二进制 组合时,可以设置命令内容 或 J ^或 Λ:。 r43或这些命令内容 、 Xord,2 ^ XonU的任意组合来承载指示信息。
例如, 可以设置 X。diJ, X。dt2, X。di3= "001 " 且 X ,尸 " Γ , 用来指示 UE切 换传输时间间隔; 设置 XodtJ' x喊 2' x喊 3= "001 " 且 x。w尸 "0" , 用来指示 UE 不进行传输时间间隔的切换。
在该实施例中, 基站利用 HS-SCCH order来承载要求 UE切换传输时间 间隔的切换指示信息, 不仅充分地利用了现有资源, 提高了资源利用率, 而 且操作简单, 易于实现, 并且与现有技术的兼容性比较好。
在上述实施例的步骤 S 120 中, UE 可通过在增强专用物理控制信道 ( E-DCH Dedicated Physical Control Channel, 简称为 "E-DPCCH" , 其中 Enhanced Dedicated Transport ChanneK增强专用传输信道)简称为 "E-DCH" ) 上发送与当前传输时间间隔中禁止使用的传输块相对应的传输格式合并指 示( E-DCH Transport Format Combination Indicator E-DCH,简称为 "E-TFCI" ) 来承载切换确认信息。
例如, 当基站要求 UE从 2ms TTI切换到 10ms TTI时, 当前传输时间间 隔为 2ms, 在 E-TFCI与传输块大小的任意一个对应表格中, 至少有一个传 输块被禁止使用, 被禁止使用的传输块的大小为 N/A。 表 1和表 2分别示出 了在 2ms TTI的情况下 E-TFCI与传输块大小的对应表格。 在表 1 中, 当 E-TFCI=120 时, 对应的传输块大小为 N/A, 该传输块被禁止使用。 在表 2 中, 当 E-TFCI=101时, 对应的传输块大小为 N/A, 该传输块被禁止使用, 或当 E-TFCI=102, 对应的传输块大小为 N/A , 该传输块也被禁止使用。 表 1

29 1884 59 6438 89 13848 1 19 21774 因此, 当 UE接收到来自基站的切换指示信息时, 例如基站要求 UE从 2ms TTI切换到 10ms TTI时, UE可以在 E-DPCCH信道上发送与 2ms TTI 中禁止使用的传输块相对应的 E-TFCI , 例如采用表 1中的 E-TFCI= 120, 或 采用表 2中的 E-TFCI=101或 102, 以向基站确认接收到该切换指示信息, 并告诉与该 UE通信的所有基站 (包括服务小区内的基站和非服务小区的基 站 ) UE将从 2ms TTI切换到 10ms TTI。 由于基站向 UE发送切换指示信息 之后才接收到与禁止使用的传输块相对应的 E-TFCI, 因此基站不会误认为 E-DPCCH信道发送的该 E-TFCI错误。
此时, UE停止增强专用物理数据信道 ( E-DCH Dedicated Physical Data Channel, 简称为 "E-DPDCH" )的数据发送, 并为了防止基站误检测或者没 有检测到 E-DPCCH 信道,可以把停止的 E-DPDCH 信道的功率分配给 E-DPCCH信道使用, 从而可以进一步保证基站能够正确地解调 E-DPCCH 信道。 UE可在 E-DPCCH信道上连续的 TTI内多次发送相同的 E-TFCI, 以 保证基站正确接收, 此时不需要基站进行 ACK/NACK ( Acknowlegdement
(反馈确认), 简称为 "ACK" , Non- Acknowlegdement (反馈非确认), 简 称为 "NACK" ) 反馈。 发送次数优选地考虑使得 UE 在某个连接帧号
( Connection Frame Number, 简称为 "CFN" ) 的开始位置连续发送五个子 帧或五的倍数个子帧, 然后在下一个 CFN边界切换到 10ms TTI。 基站只要 在某个 CFN中收到与禁止使用的传输块相对应的 E-TFCI, 则默认为 UE在 下一个 CFN切换到 10ms TTI。 由此, UE能够快速地完成传输时间间隔的切 换, 从而能够快速地提高上行覆盖范围。
在本发明实施例的步骤 S120中, UE还可以通过在 E-DPDCH信道的媒 体接入控制头 (Medium Access Control, 简称为 "MAC" ) 或调度信息中加 入指示符来承载切换确认信息。 在此情况下, 如图 2所示, 根据本发明实施 例的切换方法在步骤 S120之后还可包括步骤 S121,, 获取基站对切换确认 信息进行反馈的反馈信息, 其中, 步驟 S130包括步骤 S131 , 当接收到基站 的所述反馈信息后, 在下一个连接帧号进行传输时间间隔的切换。
例如, 当基站要求 UE从 2ms TTI切换到 lOms TTI时, E-DPDCH信道 的 MAC头或者调度信息可包括承载切换确认信息的指示符, 以确认接收到 该切换指示信息并将进行传输时间间隔的切换。 该指示符可以分为两个部 分, 即包括消息的类型和内容, 或者只包含几个比特。 例如该指示符 P包括 1个比特, 可以定义?= "1" 表示进行切换, 定义 P= "0" 表示不切换。
UE还可以在 E-DPDCH信道上连续的 TTI的 MAC头或者调度信息中加 入指示符, 以保证基站正确接收。 在此情况下, UE 需要等待基站进行 ACK/NACK反馈。 当 UE收到基站最后一个 ACK/NACK反馈后, 将在下一 个 CFN从 2ms TTI切换到 10ms TTI。 由此, UE能够快速地完成传输时间间 隔的切换, 从而能够快速地提高上行覆盖范围。
在本发明实施例的步骤 S130 中, 进行传输时间间隔的切换包括: 获取 切换传输时间间隔的重配资源并在下一个连接帧号进行传输时间间隔的切 换, 其中, UE 进行传输时间间隔切换的重配资源可以由无线网络控制器 ( RNC )通过广播下发给 UE, 优选地, UE进行传输时间间隔切换的重配资 源可以作为默认资源保存在该 UE中, 由此更快捷地完成传输时间间隔的切 换, 提高上行覆盖范围。
在本发明的另一实施例中, 切换传输时间间隔的切换方法在步骤 S110 之前还可以包括步驟 S100, 上报用户设备的最大传输功率与专用物理控制 信道功率的比值, 用户设备的所述最大传输功率与专用物理控制信道功率的 比值用于基站来确定用户设备的上行发射功率是否受限, 其中步驟 S110可 以包括步骤 S111 :接收基站在确定用户设备的上行发射功率受限时发送的切 换指示信息, 如图 3所示。 优选地, 基站通过 UE上报的用户设备最大传输功率与专用物理控制信 道功率的比值( UE Power Headroom, 简称为 "UPH" ) 来确定 UE的上行发 射功率是否受限。 基站根据 UE提供的 UPH可计算出 UE的最大发射功率, 若此最大发射功率超过了 RNC给 UE配置的最大功率,则可认为 UE功率受 限, 由此需要 UE从 2ms TTI切换到 10ms TTI以增强上行覆盖范围。
本发明实施例还提供了一种切换方法, 如图 4所示, 该切换方法包括: 步骤 S210, 向用户设备发送要求该用户设备切换传输时间间隔的切换 指示信息; 以及
步驟 S220, 接收该用户设备对该切换指示信息进行确认的切换确认信 息。
由于基站直接通知用户设备进行传输时间间隔的切换, 避免了基站通过 无线网络控制器来通知用户设备进行传输时间间隔的切换, 由此能够减少切 换传输时间间隔的时延, 从而能够实现快速地进行传输时间间隔的切换。
在上述实施例的步骤 S220 中 , 基站接收的切换确认信息可以由用户设 备在增强专用物理控制信道上通过与当前传输时间间隔中禁止使用的传输 块相对应的传输格式合并指示来发送, 或可以由用户设备通过在增强专用物 理数据信道的媒体接入控制头或调度信息中加入指示符来发送。 当基站接收 到用户设备通过在增强专用物理数据信道的媒体接入控制头或调度信息中 加入指示符发送的切换确认信息时 , 本发明实施例的切换方法在步骤 S220 之后还可包括步骤 S230, 向用户设备发送对该切换确认信息进行反馈的反 馈信息。 当用户设备收到该反馈信息后, 用户设备在下一个 CFN进行传输 时间间隔的切换。
如图 5所示, 在本发明的另一实施例中, 用于切换传输时间间隔的切换 方法在步驟 S210之前还可以包括步骤 S200 , 接收用户设备上报的最大传输 功率与专用物理控制信道功率的比值,其中, 步驟 S210可以包括步骤 S211 : 根据改最大传输功率与专用物理控制信道功率的比值确定该用户设备的上 行发射功率受限后向该用户设备发送要求该用户设备切换传输时间间隔的 切换指示信息。 在该步骤 S211 中, 基站可通过下发高速共享控制信道命令 ( High-Speed Shared Control Channel order, 简称为 "HS-SCCH order" )或其 他合适的方式来承载切换指示信息。
在本发明的再一实施例中, 用于切换传输时间间隔的切换方法在步驟 S220之后还可以包括步骤 S240 , 向无线网络控制器发送用户设备已经切换 传输时间间隔的切换完成信息。 UE 完成传输时间间隔的切换后, 基站可以 将 UE已经切换传输时间间隔的切换完成信息通知给无线网络控制器, 从而 为在切换后的传输时间间隔中的通信做好准备。 优选的是基站通过下发 NBAP ( Node B Application Part )信令来承载该切换完成信息。
因此, 根据本发明实施例的切换方法和切换方法能够有效地减少切换传 输时间间隔的时延, 从而能够快速地完成传输时间间隔的切换, 实现快速地 提高用户设备的上行覆盖范围。 并且, 本发明实施例能够充分地利用网络资 源, 并采用多种不同的方式将切换确认信息方便且快捷地发送给基站。
