在本实施例中, 终端设备可通过发送上述连接重建信息, 使得网络侧根据该连接 重建信息进行相应的失败原因分析或连接重建过程优化。
在本实施例中, 该连接重建信息包括的信息可为以下几种情况:
第一, 在将上述①-⑥种信息都统称为预定名称的一种信息时, 如统称为连接新 建的信息, 这样, 该连接重建信息为该 "连接新建的信息"。 只要发生上述①-⑥中的 任意一种或一种以上的情况, 即可将 "连接新建的信息"向网络侧发送, 以使网络侧 根据该信息进行相应分析和优化。这样,该信息可通过 1个比特发送,可以节省信令。
第 2, 将上述①-⑥中的一部分信息统称为预定名称的一种信息时, 该连接重建 信息包括该预定名称的一种信息、以及处理该部分信息以外的其他信息中的一个或一 个以上信息。

步骤 201, 终端设备在发生无线链路失败或切换失败后, 连接重建过程发生失败 后, 重新成功连接到网络;
在本实施例中, 该终端设备进行 RRC连接重建, 其中该 RRC连接重建过程与现有 技术类似, 此处不再赘述。
步骤 202, 该终端设备向网络侧报告该连接重建信息; 其中, 该连接重建失败信息可在 RLF报告中向网络侧发送, 但不限于此, 还可利 用其他消息向网络侧发送;
该连接重建信息为连接重建失败信息, 如上所述, 可为上述相关信息中的一种或 几种, 以下举例说明:
例如, 在该终端设备在连接重建过程中向网络侧发送连接重建请求后, 收到网络 侧返回的连接重建拒绝 (RRC Connection Reestabl ishment Reject) 消息时, 该连 接重建失败信息可为连接重建请求被拒绝。
例如, 在连接重建过程中, 首先进行小区选择, 并且计时器 T311在初始化 RRC 连接重建过程时启动, 当该终端设备选择到一个合适的小区 (如 E-UTRA小区) 或者 选择到另一个接入技术 (RAT)的小区时, 该计时器 T311停止, 如果该计时器 T311超 时, 表明该终端设备没有合适的小区可选, 连接重建失败, 这样, 该终端设备向网络 侧发送的连接重建失败信息可为在初始的小区选择过程中在预定时间内没有选到合 适的小区; (在 RRC连接重建中, 该连接重建失败信息可为 T311超时)。
例如, 在连接重建过程中, 在初始的小区选择过程中选择到合适的小区时, 启动 计时器 T301, 在向网络侧发送 RRC重建连接请求 (RRC Connection Reestabl ishment Request ) 消息后, 如果在预定时间内 (T301超时) 还没有收到网络侧返回的重建连 接响应 ( RRC Connection Reestabl ishment Response ) 消息, 或者在预定时间内 (计 时器 T301超时) 还未向网络侧发送 RRC连接重建请求消息, 表明连接重建失败, 这 样,该终端设备向网络侧发送的连接重建失败信息可为在预定时间内未收到连接重建 响应消息; (在 RRC连接重建中, 该连接重建失败信息可为 T301超时)。
例如, 在连接重建过程中, 如果在初始的小区选择过程中选择到合适的小区时, 但预定时间未超时前(如 T301记时期间), 选择的小区变得不合适, 表明连接重建失 败,这样,该终端设备向网络侧发送的连接重建失败信息可为选择的小区变得不合适; 其中, 具体判断选择的小区变得不合适可根据所选择小区的信号强度或质量, 基于预 定准则来判断, 该判断过程与现有技术类似, 此处不再赘述。
例如, 在连接重建过程中, 如果在初始的小区选择过程中选择了属于其他接入技 术 (Radio Access Technology) 的小区, 表明连接重建失败, 这样, 该终端设备向 网络侧发送的连接重建失败信息可为在初始的小区选择过程中选择了与当前网络的 接入技术不同的其他小区。 在上述实施例中,终端设备可使用发送该连接重建信息的消息中的 6个比特来承 载上述信息。
此外, 为了节省信令, 在本实施例中, 该连接重建信息还可采用其他方式方式, 例如, 预先将上述 6种信息都统称为 "进行连接新建的信息", 这样, 在该终端设备 确定发生了步骤 201的情况时, 在步骤 202中向网络侧上报的该连接重建信息为 "进 行连接新建的信息", 这样可占用尽量少的比特。 这样, 网络侧可根据上述信息进行 失败原因分析、 和 /或连接重建过程优化。
例如,预先将计时器 T301超时和 T301计时期间所选小区变得不合适进行命名为 新的信息 " RRC连接重建过程信令交互不成功", 这样, 在步骤 201 中, 终端设备确 定发生了上述两种情况其中之一或之二,在步骤 202中向网络侧发送的连接重建信息 为 " RRC连接重建过程信令交互不成功"; 例如, 预先将计时器 T311超时和选择了其 他接入技术的小区命名为"预定时间内无法选择合适的小区",如当前的 E-UTRA小区, 这样, 在步骤 201 中, 终端设备确定发生了上述两种情况其中之一或之二, 在步骤 202 中向网络侧发送的连接重建信息为 "预定时间内无法选择合适的小区"。 以上仅 为例举, 但不限于上述情况, 对于本领域技术人员来讲, 可根据实际情况来确定。
由上述步骤可知, 在连接重建过程失败后, 终端设备将该连接重建信息向网络侧 报告, 这样, 网络侧在获得该原因后, 可准确确定导致 RLF或 H0F失败的原因、 和 / 或连接重建失败原因、 和 /或进行连接重建过程优化。
在本实施例中, 在终端设备侧, 还可包括以下步骤:
步骤 203, 记录该连接重建信息;
在本实施例中,在发生连接重建失败后,可在任意时刻记录该连接重建失败信息, 例如, 可在发生连接重建失败时 (即在执行离开 RRC— C0NNECTDE的操作之前), 记录 该连接重建失败信息, 当然在此后的任意时刻记录该原因也可以。
在网络侧, 包括如下步骤:
步骤 204, 接收终端设备上报的连接重建信息;
在本实施例中,该终端设备可向其重新连接到网络所在服务小区的基站上报上述 连接重建信息。
步骤 205, 根据该连接重建信息确定导致无线链路失败或切换失败的原因、 和 / 或连接重建失败原因、 和 /或进行连接重建过程优化; 在本实施例中,该服务小区基站可基于该连接重建信息确定 RLF或 H0F失败的原 因, 以下举例说明:
例如, 当接收到的连接重建信息终端设备的连接重建请求被拒绝时, 网络侧可确 定导致 RLF或 H0F的原因不是移动性问题; 其中, 移动性问题可包括切换参数等设置 不合适, 如该切换参数可包括触发测量报告的时间 (TimeToTrigger), 小区特有偏置 (CelllndividualOffset ) 等参数;
例如, 当该连接重建信息是在初始的小区选择过程中没有选到合适的小区, 即计 时器 T311超时时, 网络侧可确定导致 RLF或 H0F的原因是发生该 RLF或 H0F的位置 存在覆盖空洞,例如该覆盖空洞是指该终端设备所在服务小区在内的所有能为该终端 提供服务的小区无法覆盖或无法服务用户的区域;
例如,在该连接重建信息是在初始的小区选择过程中选择了与当前网络的接入技 术不同的其他小区时,网络侧可确定导致 RLF或 H0F的原因是该终端设备成功连接到 网络所在的小区与其他小区的切换设置不合适, 例如当前小区为 E-UTRAN小区, 如果 接收到上述信息,则确定导致 RLF或 H0F的原因是切换到其他 RAT小区件的切换设置 不合适;
例如, 在该连接重建信息是在预定时间内未收到连接重建响应消息 (即计时器 T301超时) 或者选择的小区变得不合适时, 在从发生 RLF或 H0F到发送该连接重建 信息或无线链路失败报告的时间小于预设值,网络侧从 RLF报告中的测量结果获知在 发生 RLF或 H0F时该终端设备成功连接到网络时所在小区信号较好时, 在确定导致 RLF或 H0F的原因时, 将该终端设备成功连接到网络时所在服务小区看作是终端设备 能够成功建立连接的小区, 此时忽略 RLF 报告中重建小区的信息 (如重建小区标识 Reestablishment Cell Id); 在这种情况下, 根据不同的情况来确定使用的时间, 其 中, 在该连接重建信息包含在 RLF报告中发送时, 发送该连接重建信息的时间就是发 送 RLF报告的时间; 在该连接重建信息不包含在 RLF报告中发送时, 如果发送该连接 重建信息的时间与发送该 RLF报告的时间相同,即发送该连接重建信息的时间就是发 送 RLF报告的时间; 在该连接重建信息不包含在 RLF报告中发送时, 如果发送该连接 重建信息的时间与发送该 RLF报告的时间不同时,可根据具体的情况来定使用发送该 连接重建信息或无线链路失败报告的时间。对于这种情况, 以下将结合附图 4举例进 行说明, 此处不再赘述; 或者, 对于这种情况, 在收到上述连接重建信息时, 不将该终端设备发送的无线 链路失败报告作为判定无线链路失败或切换失败的原因的依据; 其中, 在该连接重建 信息包含在该 RLF报告中时, 在判断无线链路失败或切换失败的原因时, 不将该 RLF 报告中除了该连接重建信息以外的信息作为判断依据,即不将与现有技术中相同的信 息作为判断依据; 另外, 在该连接重建信息不包含在该 RLF报告中时, 此时 RLF报告 中包含的信息与现有技术类似, 这样, 在判断无线链路失败或切换失败的原因时, 不 将该 RLF报告中的信息作为判断依据。
在本实施例中,该服务小区基站还可基于该连接重建信息确定导致连接重建失败 原因;
例如, 在该连接重建信息是在预定时间内未收到连接重建响应消息时, 可确定导 致连接重建失败的原因是上行链路或下行链路存在问题;
例如, 在该连接重建信息是选择的小区变得不合适时, 还可进一步确定导致连接 重建失败的原因下行链路存在问题。
在本实施例中, 该服务小区基站还可基于该连接重建信息进行连接重建过程优 化。例如,可根据该连接重建信息优化小区选择的参数(如小区选择的信号强度参数, 小区选择的信号质量参数, 参见 TS36. 331 vl l. 1. 0), 和 /或随机接入过程的参数(如 随机接入信号的选择, 随机接入资源的分配, 随机接入信号的发送功率等, 参见 TS36. 331 vl l. 1. 0)。
由上述实施例可知, 通过本发明实施例, 网络侧可根据连接重建信息确定 FLF或 H0F的原因、 和 /或连接重建失败原因、 和 /或进行连接重建过程优化。
在网络侧, 还可包括以下步骤:
步骤 206, 将收到的该连接重建信息发送给目标基站;
步骤 207, 该目标基站接收到该连接重建信息后, 根据该连接重建信息确定导致 无线链路失败或切换失败的原因、和 /或连接重建失败原因、和 /或进行连接重建过程 优化;
其中具体的方法如步骤 205中所述, 此处不再赘述。
在上述实施例中, 该服务小区基站可不进行步骤 205, 步骤 205为可选步骤; 同 理, 步骤 206和 207也为可选步骤, 只是在网络侧需要进行失败原因分析或优化时执 行。 在本实施例中, 还可包括以下步骤:
在终端设备侧:
步骤 208, 记录成功连接到网络时终端设备所属小区的标识信息;
在本实施例中, 该标识信息可包括小区全网唯一的标识 (如 CellGloballd EUTRA)、 或者物理小区标识 (PhyCellld) 和载波频率 (ARFCN-ValueEUTRA) ;
在本实施例中, 在该终端设备成功建立连接后的任意时刻记录。
步骤 209, 向网络侧报告该标识信息;
其中, 向该终端设备所在小区基站发送该标识信息, 终端设备可在成功连接到网 络后的任意时刻发送该标识信息, 或者该步骤 209可与步骤 202同时执行, 即将步骤 202和 209合并为一个步骤。
在网络侧:
步骤 210, 接收该标识信息;
其中, 该服务小区基站接收该标识信息。
步骤 211, 向目标基站发送该标识信息;
在本实施例中, 该目标基站是指判断造成 RLF或 H0F原因的基站、 和 /或确定导 致连接重建失败原因和 /或进行连接重建过程优化的基站;
该服务小区基站可在任意时刻发送该标识信息, 也可与步骤 206同时发送, 也可 将步骤 206和步骤 211合并为一个步骤执行;
其中基站间的信息发送可由 TS36. 423vl L 2. 0 中定义的 RLF 指示 ( RLF indication) 消息和 /或 HO报告 (HO Report ) 消息完成, 但不限于上述消息, 还可 采用其他消息发送;
此外, 该服务小区基站通过一跳或一跳以上向该目标基站发送该信息; 上述步骤 208-211为可选步骤,该标识信息在该服务小区基站接收到的连接重建 信息是在预定时间内未收到连接重建响应消息 (即计时器 T301超时) 或者选择的小 区变得不合适时, 在确定导致 RLF或 H0F的原因时, 将该终端设备成功连接到网络时 所在服务小区看作是终端设备能够成功建立连接的小区,而忽略 RLF报告中重建小区 的信息 (如重建小区标识 Reestablishment Cell Id);
在上述实施例中, 在终端侧, 步骤 203和 208执行的顺序可任意, 不限于本发明 实施例的顺序, 在网络侧, 步骤 205、 步骤 206、 210的执行的顺序可任意, 不限于 实施例的顺序。此外, 对于步骤 202、 209可合并执行; 步骤 206、 211也可合并执行。 由上述本实施例可知, 终端设备在发生 RLF或 H0F后, 连接重建过程失败后, 成 功连接到网络时, 向所在服务小区基站发送连接重建信息, 当该服务小区的基站接收 到该信息后, 根据该原因确定导致 RLF或 H0F的原因、或者确定导致连接重建失败原 因、 或者进行连接重建优化; 或者该基站收到该信息后发送给目标基站, 由目标基站 进行判断。 此外, 终端设备还可记录上述连接重建信息, 以及所在服务小区的标识信 息;并且还可将该标识信息通知服务小区基站;该服务小区基站接收到该标识信息后, 可向网络侧的目标基站发送该标识信息。
在上述实施例 2中, 以终端设备发生 RLF或 H0F后, 进行连接重建且重建失败为 例进行的说明, 对于终端设备发生 RLF或 H0F后, 未进行连接重建, 直接连接到网络 的情况, 与实施例 2的不同之处在于: 在步骤 201中, 在发生 RLF或 H0F后, 未进行 连接重建, 而成功连接到网络; 此外, 在步骤 202-207中的连接重建信息为未进行连 接重建的信息; 在步骤 205和 207中, 网络侧可根据该信息确定导致 H0F或 RLF的原 因并非是移动性问题(如切换参数设置不合适)、和 /或根据该连接重建信息进行连接 重建过程优化, 如上述实施例所述。 对于与实施例 2相同的步骤此处不再赘述。
图 3是本发明实施例 3的报告连接重建失败原因的方法流程图。与实施例 2类似, 可包括步骤 301至 307, 与实施例 2所述的步骤 201-207类似, 步骤 308与步骤 206、 步骤 310与步骤 211类似, 此处不再赘述, 其中步骤 308为可选步骤; 步骤 306和步 骤 310可合并。
另外, 如图 3所示, 与实施例 2的不同之处在于, 在网络侧生成该终端设备所在 服务小区的标识信息, 不需要终端设备发送。
如图 3所示, 包括:
步骤 309, 生成该终端设备所在服务小区的标识信息;
其中, 该终端设备在所在小区成功建立 RRC连接后, 该小区的基站即可生成该小 区的标识信息, 可根据现有的任何一种技术生成, 此处不再赘述。
步骤 310, 将该标识信息向目标基站发送。
在上述实施例 3中, 与实施例 2类似, 步骤 308至 310为可选步骤。
在上述实施例 3中, 以终端设备发生 RLF或 H0F后, 进行连接重建且重建失败为 例进行的说明, 对于终端设备发生 RLF或 H0F后, 未进行连接重建, 直接连接到网络 的情况, 与实施例 3的不同之处在于: 在步骤 301中, 在发生 RLF或 H0F后, 未进行 连接重建, 而成功连接到网络; 此外, 在步骤 302-307中的连接重建信息为未进行连 接重建的信息; 在步骤 305和 307中, 网络侧可根据该信息确定导致 H0F或 RLF的原 因并非是移动性问题(如切换参数设置不合适)、 和 /或进行连接重建过程优化。 对于 与实施例 2相同的步骤此处不再赘述。
图 4是本发明实施例 4的报告连接重建信息的小区示意图。 其中以 T301超时为 例进行说明本发明实施例。
如图 4所示, 终端设备从小区 A切换到小区 B。 该终端设备在切换完成后很短时 间内发生了 RLF或在切换过程中发生了 H0F。 然后该终端设备初始化 RRC连接重建过 程并在小区选择过程中将小区 A选择为合适小区, 这样, RLF报告中的重建小区标识 ( Reestabl ishment Cel l Id) 为小区 A的标识信息, 并且该重建小区标识可通过 RLF 报告向网络侧发送。
在完成 RRC连接重建过程之前, T301超时 (在预定时间内未收到连接重建响应 消息), 然后该终端设备重新连接到服务小区, 如小区 (:, 并且该新建小区的标识也 通过 RLF报告向网络侧发送。
在重新连接到小区 C后,该终端设备向小区 C的基站发送连接重建信息,即 T301 超时, 例如通过 RLF报告向小区 C发送;
小区 C的基站接收到该信息后,若进一步判断从 RLF或 H0F发生到连接重建信息 或 RLF报告发送所经历的时间小于某个门限值、 且该终端设备在小区 C按照 RRC 连 接建立过程成功建立的连接、在终端设备发生 RLF或 H0F时小区 C有较好的信号质量, 则网络侧忽略 RLF报告中连接重建的小区标识, 即小区 A的标识, 确定如果终端设备 在 RRC连接重建过程中选择小区(:, 这个过程就能成功, 因此, 最终确定造成 RLF或 H0F的原因是切换到错误的小区, 即从小区 A切换到小区 B是错误的, 应该切换到小 区 (:。 但是, 如果根据现有的协议, 就会判定造成 RLF或 H0F的原因是从小区 A到小 区 B的切换太早了。
由上述实施例可知,网络侧可根据终端设备发送的连接重建信息准确地确定导致 RLF或 H0F的原因, 以进一步进行网络参数的优化。
此外, 如果网络侧根据收到的连接重建信息知道用户重建失败的原因是 T301超 时或选择的小区不再合适时, 则不将该终端设备发送的 RLF报告作为判断 RLF或 H0F 失败原因的依据。
图 5是本发明实施例 5的报告连接重建信息的小区示意图。 其中以 T301超时为 例进行说明本发明实施例。
如图 5所示, 终端设备从小区 A切换到小区 B。 该终端设备在切换完成后很短时 间内发生了 RLF或在切换过程中发生了 H0F。 然后该终端设备初始化 RRC连接重建过 程并在小区选择过程中将小区 C选择为合适小区, 这样, RLF报告中的重建小区标识 (Reestablishment Cell Id) 为小区 C的标识信息, 并且该重建小区标识可通过 RLF 报告向网络侧发送。
在完成 RRC连接重建过程之前, T301超时 (在预定时间内未收到连接重建响应 消息), 然后该终端设备重新连接到服务小区, 如小区 D, 并且该新建小区的标识也 通过 RLF报告向网络侧发送。 其中, 如前所述, 在预定时间内未收到连接重建响应消 息可包括两种情况: 1 ) 在发送连接重建请求后, 未收到网络侧返回的连接重建响应 消息; 2) 在预定时间内未能发送该连接重建请求。
在重新连接到小区 D后,该终端设备向小区 D的基站发送连接重建信息,即 T301 超时, 例如通过 RLF报告向小区 D发送;
小区 D的基站接收到该信息后,若进一步判断从 RLF或 H0F发生到 RLF报告发送 所经历的时间小于某个门限值、 且该终端设备在小区 D按照 RRC 连接建立过程成功 建立的连接、且在终端设备发生 RLF或 H0F时小区 D有较好的信号质量, 则网络侧忽 略连接重建的小区标识, 即小区 C的标识, 确定如果终端设备在 RRC连接重建过程中 选择小区0, 这个过程就能成功, 因此, 最终确定造成 RLF或 H0F的原因是切换到错 误的小区, 即从小区 A切换到小区 B是错误的, 应该切换到小区0。
由上述实施例可知,网络侧可根据终端设备发送的连接重建信息准确地确定导致 RLF或 H0F的原因、 连接重建失败原因、 连接重建过程优化。
此外, 如果网络侧根据收到的连接重建信息知道用户重建失败的原因是 T301超 时或选择的小区不再合适时,则不将该 RLF报告作为判断 RLF或 H0F失败原因的依据。
