一种处理数据传输异常的方法及系统、 宏基站
本申请要求于 2013年 7月 2日提交中国专利局、 申请号为 201310274681.6、 发明名称为"一种处理数据传输异常的方法及系统、 宏基站 "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 本发明涉及移动通信技术领域, 特别涉及一种处理数据传输异常的方法 及系统、 宏基站。 背景技术 随着移动通信技术的发展和使用移动数据业务的人数的增加, 现有的宏 蜂窝的负载越来越重, 为了给用户提供更好的服务, 3GPP引入了载波聚合 ( Carrier Aggregation, CA )技术, 该技术可以利用聚合多个离散或连续的小 带宽频段以支持更高带宽的传输, 其中, 每一个被聚合的频段称为成员载波 ( Component Carrier, CC ) 。 CA技术支持用户设备 ( User Equipment, UE ) 同时使用多个成员载波进行上下行通信, 从而支持高速数据传输。 在 CA技术中, 在 UE发送数据时, 除了使用 MC ( macro, 宏基站)发送, 还可以使用 SC ( small cell, 微基站)发送。 SC指的是覆盖范围比较小, 发射 功率比较小的站点, 例如 HeNB ( Home eNB, 家庭基站) 、 ico (微基站) 、 RRH ( Radio remote head , 射频拉远)等, 其可以和 MC协同为 UE提供服务, 提供更大的吞吐量。 在协同分工中, macro提供广覆盖, 负责控制信令, SC 提供用户数据增强, 承担部分或全部的用户数据业务。
一种典型的基站协同工作的场景如图 1所示。 图 1中, 长方体为一些建筑, 在其边缘或者内部也包含了 MC。 F1为 MC 覆盖的范围, F2为 SC覆盖的范围。 可以看出, 图 1中的 UE分别与两个基站传 输数据, 使用的是 "跨站多流" 模式传输业务。 即 SC和 MC同时承担用户数 据业务的传输(即业务分流) , 以支持高速数据传输。 但是上面的协调分工方式也存在一定的缺点, 当 SC和 MC协同为 UE提供 数据分流时, 如果 UE此时在 SC的传输业务处于 DRX ( Discontinuous receiving/transmitting , 不连续接收)状态, 而正准备从 DRX进入到连续接收 状态, 此时若 UE脱离 SC的覆盖范围, 那么 UE则无法检测到 SC的信号, 无法 进行数据传输。 而现有技术在检测不到 SC的信号之后, 则执行 RRC ( Radio Resource Control, 无线资源控制) 重建立过程, 但是, 该方案仅针对只有一个小区的 处理方案, 若两个小区存在时, 若执行 RRC重建立过程会浪费资源, 因此, 现有技术还是没有很好地解决若 UE脱离 SC的覆盖范围, UE无法检测到 SC 的信号, 无法进行数据传输的问题。

S201 , 宏基站 MC接收用户设备或者第一微基站 SC发送的检测报告。 S202, MC根据检测报告, 重新选定通信节点以替代第一微基站 SC为用 户设备传输数据。
MC除了检测报告之外, 还可以参考 UE发送的测量报告、 网络负载等信 息来选择替代节点。
具体的,在 S201的实施过程中,检测报告是用来告知 MC用户设备与第一 微基站 SC之间数据传输异常。
下面介绍该检测报告的具体来源。 而首先, 在 MC接收用户设备发送的检测报告之前, MC与用户设备会建 立无线资源控制 RRC连接, 与第一微基站 SC同时为用户设备提供分流服务。
之后, 用户设备 UE和第一微基站 SC会根据第一微基站 SC的 DRX
( Discontinuous receiving/transmitting, 不连续接^ 1 ) 西己置, 进人 DRX模式。 而在进入 DRX模式之后, UE和第一微基站 SC之间会出现数据传输异常的 情况, 具体的, 有下面几种异常情况: 第一种:
用户设备与第一微基站 SC之间的数据传输异常, 具体包括:
在用户设备和第一微基站 SC进入 DRX模式之后,第一微基站 SC的下行信 号质量下降到设置的第一门限值。
此处的第一门限值具体可以由 MC设置, 也可以为协议规定等其他方式。 因为在 UE和第一微基站 SC进入了 DRX模式之后, UE会继续对 SC的下行 信号进行检测, 并且会将检测结果实时报告给 MC。
若此时 UE检测到 SC的下行信号质量下降到一定门限的时候, 那么 UE则 会使用媒体接入控制层的控制元素 MAC CE, 或者使用 RRC ( Radio Resource Control, 无线资源控制)信令, 或者使用物理层信令等等通知 MC, 让 MC获 知用户设备与第一微基站 SC之间的数据传输异常。
第二种: 用户设备与第一微基站 SC之间的数据传输异常, 具体为: 在用户设备从 DRX模式切换到连续接收模式之后, 用户设备检测不到第 一微基站 SC的下行信号。
在根据第一微基站 SC的 DRX配置, UE和第一微基站 SC进入 DRX模式之 后, UE会从第一微基站 SC的 DRX模式中唤醒, 切换到连续接收模式。 而在 UE和第一微基站 SC进入了 DRX模式, 一直到 UE切换到连续接收模 式的时候, UE—直在对第一微基站 SC的下行信号进行检测。
而当 UE切换到连续接收模式之后, UE已经不在 SC的覆盖范围, 那么 UE 则检测不到第一微基站 SC的下行信号。
此时, UE的检测报告会显示 UE和第一微基站 SC之间的数据传输异常, UE则会将该检测报告发送给 MC。 在发送该检测报告时, UE也可以使用 MAC CE, 也可以使用 RRC信令、 物理层信令等发送。 第三种: 用户设备与第一微基站 SC之间的数据传输异常, 具体为:
在用户设备和第一微基站 SC进入 DRX模式之后,第一微基站 SC检测到用 户设备发送的检测信号的质量下降到设置的第二门限值。
当根据第一微基站 SC的 DRX配置, UE和第一微基站 SC进入 DRX模式之 后, UE—直在发送检测信号供第一微基站 SC或者其他基站进行检测, 而对于 第一微基站 SC来说, 其实也是一直在检测 UE发送的检测信号。 因此,若第一微基站 SC检测到 UE发送的检测信号的质量下降到了设置的 第二门限值。 此时第一微基站 SC则会将该检测报告发送给 MC, 让 MC获知用 户设备与第一微基站 SC之间的数据传输异常。
当然, 若第一微基站 SC也同时检测不到 UE的信号, 此时第一微基站 SC 也会发送检测报告给 MC, 通知 MC UE已经不在服务区, 让 MC获知用户设备 与第一微基站 SC之间的数据传输异常。 当然,此处的第二门限值可以由 MC配置,也可以是协议规定等其他方式。 上面的三种情况都是用户设备与第一微基站 SC之间的数据传输异常情 况。 而当 MC接收到该检测报告之后, 则会执行 S202中的步骤。
其中, 通信节点为针对用户设备配置的第二微基站 SC, 或者, 为 MC。 具体的, 在重新选定通信节点的过程中, MC可以根据 UE和第一微基站 SC发送的检测报告, 邻居小区的负载情况等, 确定新的通信节点来替代第一 微基站 SC, 这个新的通信节点即为第二微基站。 如果没有符合条件的第二微 基站, MC可以将 UE所有在微基站的业务都转移到 MC。 从第二微基站 SC和 MC中确定一个作为通信节点替代第一微基站 SC为 UE继续传输数据。
当 MC选定了通信节点之后,则会将该重新选定通信节点替代第一微基站 SC的消息通知给第一微基站 SC,以便于将第一微基站 SC未传输完成的数据转 发到通信节点。 让通信节点继继续传输输未传输完成的数据。 当通信节点为选定为 MC时, 第一微基站 SC将本地未传输完成的待传输 数据转发到通信节点, 具体为: 第一微基站 SC将待传输数据转发到 MC。
当通信节点选定为第二微基站 SC时, 在 MC根据检测报告, 重新选定通 信节点以替代第一微基站 SC为用户设备传输数据之前, MC发送协商消息给 第二微基站 SC , 以便于确定第二微基站 SC为新的通信节点。 另外, MC还会将该消息通知给用户设备, 以便用户设备使用通信节点继 续传输数据。
而 MC将重新选定通信节点替代第一微基站 SC的消息通知给用户设备, 或者将通信节点的消息通知给第一微基站 SC, 这是两个独立的步骤, 两者可 以同时进行, 也可以有先后顺序, 此处不做限制。 具体的, 这里 MC会为 UE 进行重配置, 使得 UE明确用 MC或其他通信节点替代第一微基站。 综上,介绍了当用户设备与第一微基站 SC之间的数据传输异常之后, MC 可以重新选定通信节点为用户设备服务。 下面, 将对用户设备与第一微基站 SC之间的数据传输异常的各种情况以 及 MC的处理方式分别进行介绍。 下面请参看图 3 , 在用户设备与第一微基站 SC之间的数据传输异常时, 第一微基站 SC , MC以及用户设备之间的第一种处理方式:
5301 , MC与 UE建立 RRC连接。
5302, MC与第一微基站 SC同时为 UE提供分流服务。
5303 , 根据第一微基站 SC的 DRX配置, UE和第一微基站 SC进入 DRX模 式。
5304, UE继续对 SC的下行信号进行检测。
在 MC与第一微基站 SC同时为 UE提供分流服务时, UE就开始对第一微基 站 SC进行检测, 在两者进入到了 DRX模式之后, 会继续对其进行检测。
若此时 UE检测到 SC的下行信号质量下降到一定门限的时候, 那么 UE则 会使用 MAC CE, 或者使用 RRC信令, 或者使用 PHY层信令等等通知 MC。
5305, 将检测到异常的报告发送给 MC。
此时的异常结果是: 在 UE和第一微基站 SC进入 DRX模式之后,第一微基 站 SC的下行信号质量下降到设置的第一门限值。
5306, MC接收 UE发送的检测报告。
S307, MC根据检测报告, 重新选定通信节点以替代第一微基站 SC。 需要说明的是, MC重新选定通信节点, 还可以参考 UE的测量报告, 邻 居小区的负载情况等。 MC需要和重新选定的通信节点进行协商之后, 才能确 定这个通信节点能否为 UE提供服务。
S308, MC将通信节点通知给第一微基站 SC。
S309, MC将通信节点通知给 UE。
具体的, MC会将重新选定通信节点替代第一微基站 SC的消息通知给用 户设备, 以便用户设备使用通信节点继续传输数据。 具体的, 这里 MC会为 UE进行重配置, 使得 UE明确用 MC或其他通信节点替代第一微基站。 另外, 当选定的通信节点为第二微基站 SC时, MC还会将重新选定通信 节点以替代第一微基站 SC这一消息告知第二微基站 SC, 下面的过程一样。
下面请参看图 4, 在 UE与第一微基站 SC之间的数据传输异常时, 第一微 基站 SC , MC以及 UE之间的第二种处理方式:
5401 , MC与 UE建立 RRC连接。
5402, MC与第一微基站 SC同时为 UE提供分流服务。
5403 , 根据第一微基站 SC的 DRX配置, UE和第一微基站 SC进入 DRX模 式。
5404, 在 UE从 DRX模式切换到连续接收模式之后, UE检测不到第一微 基站 SC的下行信号。
