在实际的网络系统中, 造成链路失败的原因有多种, 但是现有技术中终端设备发 生链路失败后, 向网络侧提供的链路失败时对本小区和邻居小区的相关信息, 如测量 信息和位置信息等, 这些信息不足以使网络侧准确确定链路失败的根本原因, 因此也 不能准确地进行优化, 因此, 通过本发明实施例, 可向网络侧提供详细的信息, 如导 致链路失败的具体触发信息, 使得网络侧能准确地优化网络。
此外, 终端设备还可对导致链路失败的具体触发信息, 例如, 物理链路的问题, 介质访问控制 (MAC, Medium/MediaAccess Control ) 层的随机过程失败, 无线链路 控制 (RLC, Radio Link Contrl ) 层重传达到最大传输次数等进行分析, 获得更为具 体的导致链路失败的原因。但是在现有技术中, 终端设备没有对造成链路失败的原因 进行区分, 不能向网络侧提供具体的造成链路失败原因的信息, 因此导致网络侧不能 采用更有针对性的措施来优化网络。 因此, 通过本发明实施例, 可使得网络侧获得详 细具体的链路失败信息, 进而获得更加准确的优化网络性能。

在本发明实施例中, 造成链路失败的具体触发信息有多种, 例如, 物理链路的问 题、 介质访问控制层的随机接入问题、 上行无线链路控制层传输问题;
例如, 在用户设备在一定时间 (如 T310, 见 3GPP TS36. 331 ) 内没有收到足够多 (如 N311 个, 见 3GPP TS36. 331 ) 的链路变好的指示 (如 in-sync指示, 见 3GPP TS36. 331 ) 时, 用户设备 UE可确定链路失败的具体触发信息为物理链路的问题; 或者在用户设备接收到 MAC层随机接入过程失败的指示时,可确定链路失败的具 体触发信息为 MAC层的随机接入问题;
或者在用户设备 RLC层重传达到最大传输次数时,可确定链路失败的具体触发信 息为 RLC层传输问题。

步骤 203, 在步骤 202中确定触发了测量报告时, 该 UE可确定导致链路失败的 原因为切换配置问题;
在这种情况下,该切换配置问题可能是该 UE针对目标小区的切换参数(如小区特 定偏移量 CelllndividualOffset, 参见 TS36. 331 )设置过小, 导致该 UE在所接收到 的服务小区的信号很弱时, 该 UE还没有完成切换。

在本实施例中, 近来成功的上行传输是指: 在出现下行问题前 (如收到连续的 N310个来自底层的 out-of-sync指示), 发生成功的上行传输。
步骤 209, 在步骤 208的确定结果为存在近来成功的上行传输的情况下, 确定导 致链路失败的原因为 "覆盖空洞";
在本实施例中, 该覆盖空洞是指, 该用户设备 UE不能在上行方向上成功传输数 据包, 和 /或在下行方向上接收数据包;
在这种情况下, 该覆盖空洞仅为下行覆盖空洞, 是指不能接收下行数据包。 步骤 210, 该 UE将分析结果进行记录;
在本实施例中, 该 UE可将这种情况下的该分析结果 "覆盖空洞"记录在链路失 败报告中, 通过该报告向网络侧传送, 但不限于这种情况, 还可以将该分析结果单独 记录, 并传送给网络侧, 供网络侧分析链路失败原因或优化网络时使用;
其中, 在该物理链路的问题的情况下, 可按如下方式记录分析结果 "覆盖空洞 (物理链路的问题; 测量报告未触发; 不存在信号质量较好的邻小区; 有近来成功的 上行传输) "; 或者 "覆盖空洞 (T310 超时; 测量报告未触发; 不存在信号质量较好 的邻小区; 有近来成功的上行传输)"等方式;
其中, 该"不存在信号质量较好的邻小区; 有近来成功的上行传输"为可选信息, 可不进行记录。
步骤 211, 在步骤 208的确定结果为不存在近来成功的上行传输的情况下, 确定 导致链路失败的原因为 "覆盖空洞";
在本实施例中, 可确定为 "下行覆盖空洞, 上行未知"。
步骤 212, 该 UE将分析结果进行记录;
在本实施例中, 该 UE可将这种情况下的该分析结果 "覆盖空洞"记录在链路失 败报告中, 通过该报告向网络侧传送, 但不限于这种情况, 还可以将该分析结果单独 记录, 并传送给网络侧, 供网络侧分析链路失败原因或优化网络时使用; 其中, 在该物理链路的问题的情况下, 可按如下方式记录分析结果 "覆盖空洞 (物理链路的问题; 测量报告未触发; 不存在信号质量较好的邻小区; 没有近来成功 的上行传输) "; 或者 "覆盖空洞 (T310 超时; 测量报告未触发; 不存在信号质量较 好的邻小区; 没有近来成功的上行传输)"等方式;

由上述实施例可知, 在链路失败属于物理链路问题的情况下, 该 UE可根据上述 过程对导致链路失败的具体原因进行分析, 将分析结果上报给网络侧, 这样网络侧可 根据该 UE上报的信息对链路失败的原因进行分析, 以进行更加准确的网络优化。

步骤 311, 在步骤 303中, 在判断结果为否时, 该 UE确定导致链路失败的原因 是切换配置问题;
在本实施例中, 具体地是切换参数问题, 可能是该 UE针对目标小区的切换参数 (如小区特定偏移量 CelllndividualOffset, 参见 TS36. 331 ) 设置过小, 导致该 UE 在所接收到的服务小区的信号很弱时, 该 UE还没有完成切换。
步骤 312, 该 UE将分析结果进行记录;

步骤 315, 在步骤 307中, 在确定结果为是时, 该 UE确定导致链路失败的原因 为切换配置问题;
其中, 具体地, 该切换配置问题可能是该 UE针对目标小区的切换参数 (如小区 特定偏移量 Cel l lndividualOffset, 参见 TS36. 331 )设置过小, 导致该 UE在所接收 到的服务小区的信号很弱时, 该 UE还没有完成切换。
步骤 316, 该 UE将分析结果进行记录;
在本实施例中, 该 UE可将这种情况下的分析结果 "切换配置问题"记录在链路 失败报告中, 通过该报告向网络侧传送, 但不限于这种情况, 还可以将该分析结果单 独记录, 并传送给网络侧, 供网络侧分析链路失败原因或优化网络时使用;

步骤 317~321, 该 UE将分析结果向网络侧发送;
在本实施例中, 可将该分析结果包含在链路失败报告中向网络侧发送, 此外也可 单独发送, 此外, 可在该网络侧请求的时候再发送, 也可获得后就发送, 在具体实施 中, 可根据具体情况确定。
在上述实施例中, 需要说明的是, 步骤 306、 312、 310、 314和 316为可选步骤, 此外, 图 3所示的过程仅为本发明实施例, 对于本领域技术人员来讲, 可根据实际需 要设置各个步骤, 只要符合以下条件即可, 在触发了测量报告且未成功发送测量报告 时, 确定链路失败原因是切换配置问题; 在触发了测量报告且测量报告发送成功, 未 成功发送切换完成消息时, 确定链路失败原因是切换配置问题; 在未触发测量报告且 存在信号质量好的邻小区时, 确定链路失败的原因是切换配置问题; 在未触发测量报 告、不存在信号质量好的邻小区且在链路失败前存在近来成功的下行传输时, 确定链 路失败的原因仅是上行覆盖空洞; 在未触发测量报告、不存在信号质量好的邻小区且 在链路失败前不存在近来成功的下行传输时, 确定链路失败的原因是上行覆盖空洞, 且下行未知。
由上述实施例可知, 在链路失败属于上行 RLC传输问题的情况下, 该 UE可根据 上述过程对导致链路失败的具体原因进行分析, 将分析结果上报给网络侧, 这样网络 侧可根据该 UE上报的信息对链路失败的原因进行分析, 以进行更加准确的网络优化。

图 4是本发明实施例 5的分析链路失败原因的方法流程图。针对用户设备发生链 路失败时, 该 UE所在的基站, 如图 4所示, 该方法包括:
步骤 401, 获取用户侧发送的导致链路失败的原因的信息;
在本实施例中, 该链路失败的原因的信息可为上述实施例 1-4中所述的信息; 例如, 切换配置问题 (上行 RLC传输问题; 不能发送切换完成消息); 切换配置问题 (上行 RLC传输问题; 触发测量报告; 未成功发送测量报告); 切换配置问题(上行 RLC传输问题; 未触发测量报告; 存在信号质量较好的邻小 区);
覆盖空洞 (上行 RLC传输问题; 未触发测量报告; 不存在质量较好的邻小区; 存 在近来成功的下行传输);
覆盖空洞(上行 RLC传输问题;未触发测量报告;不存在信号质量较好的邻小区; 不存在近来成功的下行传输);
切换配置问题 (T310超时; 测量报告触发);
切换配置问题 (T310超时; 测量报告未触发; 存在信号质量较好的邻小区); 覆盖空洞 (T310 超时; 测量报告未触发; 不存在信号质量较好的邻小区; 有近 来成功的上行传输);
覆盖空洞 (T310 超时; 测量报告未触发; 不存在信号质量较好的邻小区; 没有 近来成功的上行传输);
MAC层随机接入问题。
在上述信息中, 有些信息为可选信息, 如实施例 1-4所述, 此处不再赘述。 此外, 该 UE所在的基站并非直接获得上述信息, 可以是其他基站通过空口的消 息或者基站间的消息发送给该 UE所在基站,从而使得该基站获得该链路失败的原因; 在本实施例中, 该链路失败原因的信息可通过链路失败报告发送, 此外, 也可单 独发送, 或者包含在其他消息中发送。
步骤 402, 根据获取的该导致链路失败的原因、 或者根据获取的该导致链路失败 的原因并结合自身的测量结果来确定导致链路失败的原因;
在本实施例中, 该基站获得该导致链路失败的原因后, 可利用该获得的链路失败 的原因确定导致链路失败的根本原因;
此外, 在本实施例中, 为了更加准确地确定导致链路失败的根本原因, 该基站还 可根据获得的链路失败的原因确定导致链路的根本原因并结合其自身的测量结果更 加准确地确定导致链路失败的根本原因;
在本实施例中, 该自身的测量可为 SRS测量等。
图 5是本发明实施例 6的网络优化方法流程图。 针对用户设备发生链路失败时, 该 UE所在的基站, 如图 5所示, 该方法包括:
步骤 501和步骤 502, 与图 4所示的实施例 5中的步骤 401和步骤 402类似, 此 处不再赘述。
步骤 502, 在步骤 502中, 当基站确定了导致链路失败的根本原因后, 可进行相 应的网络优化。
下面举例说明基站结合自身测量结果确定导致链路失败的根本原因和网络优化 的过程; 例 1, 切换配置问题
用户设备上报以下链路失败原因: 例如, 切换配置问题 (T310 超时; 测量报告 触发); (T310超时; 测量报告未触发); (上行 RLC问题; 不能发送切换完成消息); (上行 RLC问题; 不能成功发送测量报告) 等;
该基站自身的测量结果: 该基站根据该 UE在切换过程中的信息, 基站可以判断 出该切换是切换太早, 切换太晚或切换到错误的小区;
这样, 该基站获得该 UE上报的原因后, 与其自身的判断结果, 如切换太早, 切 换太晚或切换到错误的小区进行对比, 确定导致链路失败的根据原因, 从而决定所要 调整的参数, 达到优化网络的目的。
例如, 虽然基站能够决定导致链路失败的原因是由于切换太晚, 但是如果该基站 从 UE上报的原因是 "切换配置问题 (T310超时; 测量报告触发) ", 这样, 该基站能 够根据上述信息确定应该调整哪些参数, 例如, 具有测量配置的参数, 例如, 触发时 间 (timeToTrigger, 参见 TS36. 331 ), 从而可通过调整相应的参数对网络进行优化。
例 2, 覆盖空洞
与上述分析方法类似, 用户设备上报以下链路失败原因: 覆盖空洞 (T310超时; 测量报告未触发; 有近来成功的上行传输); 覆盖空洞(T310超时; 测量报告未触发; 没有近来成功的上行传输);
如果基站能够决定链路失败的原因在于覆盖空洞, 当该基站从该 UE获得导致链 路失败的原因时, 该基站可根据其自身的测量结果和该 UE上报的分析结果决定该覆 盖空洞是上行覆盖空洞、 还是下行覆盖空洞, 还是上行和下行覆盖空洞;
具体过程如下:
基站获取用户设备上报的导致链路失败的原因, 如上行或下行或两者的覆盖空 洞; 初始化那些在发生链路失败的位置附近的用户设备的 MDT报告流程, 该基站基于 该 MDT报告, 进一步确定覆盖空洞问题。 这样, 该基站将确定的结果通知 0AM服务器 以优化网络性能。"
例 3: MAC层随机接入问题
当用户设备上报导致链路失败的原因是 MAC层随机接入的问题,该基站获得该信 息后,能够初始化那些在发生链路失败的位置附近的用户设备的随机接入信道(RACH) 报告流程, 这样可以帮助发现随机接入问题的原因。 这样, 可根据具体的原因进行 RACH的优化, 从而对网络进行优化。
由上述实施例可知, UE 根据具体的触发信息对导致链路失败的原因进行分析, 并将分析结果向网络侧提供, 使得该基站获得该分析结果后、 可根据该分析结果、 或 者再结合自身的测量结果确定导致链路失败的根本原因,从而对网络进行更准确的优 化。

以下举具体的实例对本发明实施例的分析链路失败的原因和网络优化方法进行 说明。
例 1、 物理链路的问题:
基站可以根据该具体触发信息以及测量结果决定是切换配置问题 (如切换太早, 切换太晚, 切换到错误小区) 或覆盖空洞;
该判断方式可以利用现有技术来实现,如当测量结果显示链路失败时没有信号质 量好的邻居时, 可以判定是覆盖空洞;
根据判定结果, 该基站可以通过调整 UE针对目标小区的切换参数 (如小区特定 偏移量 CelllndividualOffset, 参见 TS36. 331 ) 来解决切换配置问题, 或通过增加 基站覆盖来解决覆盖空洞问题。
例 2, 介质访问控制层的随机接入问题:
基站可以根据该具体触发信息来判定是与 MAC 层随机接入过程有关的上行链路 问题, 如发射功率设置不正确、 物理随机接入信道(PRACH, Physical Random Access Channel ) 资源配置不适当等;
基站可以通过增加发射功率或增加物理随机接入信道的资源来优化网络性能。 例 3, 上行无线链路控制层传输问题:
该基站可以根据报告的上行无线链路控制层传输问题,就可以判定上行链路的配 置不恰当, 如上行发射功率设置不对;
基站可以通过调整用户的上行发射功率来优化网络性能。
