所述 UE在开启 MRO功能后, 进而即可确定是否发生 RLF, 并在发生 RLF时, 记录 RLF信息到 RLF报告中。 其中, RLF可发生于各个阶段, 例 如, 所述 UE在切换之前发生 RLF、 所述 UE在切换过程中发生 RLF、 所述 UE在切换完成后发生 RLF。
确定 RLF的方法可以为: UE的物理层在下行 DPCCH或 F-DPCH信道 上, 连续收到 N313个" out of sync"指示后, 会启动 T313定时器。 T313到 期前,如果收到了 N315个连续的" in sync"指示,那么停止 T313;如果 T313 到期了, 就会触发" Radio Link Failure"。 具体内容详见现有技术, 此处不再 赘述。
本发明实施例在确定发生 RLF时, 记录 RLF信息单元到 RLF报告中, 其中, 所述 RLF信息单元可包括以下中的至少一者: 源服务小区的测量结 果(measResultLastServCell) , 源服务小 区 最好邻 区 的测量结果 (measResultNeighCells of best neighbouring cells) , 时间信息 ( timeH02Rlf ) , 发生无线链路失败时所在小区标识 ( failedPCellld ) , 源小区标识 ( reviousPCellld ) , 重 建无 线 资 源 连接后 所在 小 区 标识 ( reestablishmentCellld ), 连接失败类型 ( connectionFailureType )。
measResultLastServCell , 其表示 RLF发生前, 所述 UE最后所在源小 区的测量结果; 所述测量结果即所述源小区的信号质量或信号强度。
measResultNeighCells of best neighbouring cells, 其表示发生 RLF时所 述 UE所在小区的信号质量或信噪比最好的邻区的测量结果;所述测量结果 用于判断最好邻区的信号质量或信号强度。
timeH02Rlf, 其表示 RLF发生前, 所述 UE收到最后一次切换命令到 所述 UE连接失败的时间。 具体的 , 以 UTRAN网络制式向 E-UTRAN网络 制式的切换为例而言, timeH02Rlf表示 RLF发生前, 所述 UE收到最后一 次切换命令到所述 UE连接失败的时间。以 UTRAN小区到 E-UTRAN的小 区切换为例进行说明, 当所述 UE收到的切换命令是 UTRAN小区发起时, 其表示最后一次切换命令或含有 MRO启动指示切换发起到所述 UE连接失 败的时间; 当所述 UE收到的切换命令是 E-UTRAN小区发起时, 其表示 RLF发生前, 所述 UE收到最后一次切换命令到所述 UE连接失败的时间。
failedPCellld, 在所述 UE 未收到切换命令时, 其取 RLF发生时所述 UE所在小区的标识; 在所述 UE收到切换命令后, 其取切换命令中目标小 区的标 i只。
previousPCellld, 其表示下发切换命令的源小区标识, 所述切换命令使 所述 UE启动 MRO功能。
reestablishmentCellld, 其表示 UE发起重建立请求的小区的标识。
connectionFailureType , 其表示连接失败类型: HOF(Handover Failure , 切换失败)/ RLF; 如果是 HOF, 说明所述 UE未和目标小区同步成功, 或者 同步完成并完成了切换, 但是无法发送切换完成; 如果是 RLF, 说明所述 UE在目标小区发送切换完成命令成功, 并可以在目标小区发起业务后, 而 发生的连接失败。
13、 所述 UE向所述源网元上报所述 RLF报告, 以使所述源网元根据 所述 RLF ^艮告, 确定所述 UE在第一网络制式下的源小区和第二网络制式 下的目标小区间发生了过早切换、 过晚切换或切换到错误小区。 由于所述 RLF报告中记录有相应的 RLF信息单元,且对于不同的移动 性切换事件。所记录的 RLF信息单元不同,所述 UE在向所述源网元 (例如, RNC)发送 RLF报告后, 所述源网元 (例如, RNC)就可根据所述 RLF报告中 相应的 RLF信息单元确定所发生的移动性切换事件, 亦即过早切换、 过晚 切换或切换到错误小区。
下面对 RLF报告中的 RLF信息单元的用途进行相应说明。
timeHo2Rlf 可用来将过晚切换场景与过早切换、 切换到错误小区两场 景区分开。 具体地, 如果该信息单元不存在或超过了设定门限, 达到了最 大值, 则为过晚切换场景; 比如, UE在初始接入后, 在发生 RLF前 UE从 未收到触发该计时器开启的相关命令, 则该信息单元就不存在; 如果该信 息单元值小于设定门限, 则为过早切换或切换到错误小区。
previousPCellld, failedPCellld, reestablishmentCellld用来区分过早切换 和切换到错误小区。 如果 previousPcelllD和 reestablishmentCellld—样, 则 为过早切换; 口果 reestablishmentCellld 不等于 previousPCellld 和 failedPCellld则为切换到错误小区。
connectionFailureType用来区分过早切换和切换到错误小区的切换移动 性场景中切换是否完成。 如果是 HOF, 说明所述 UE未和目标小区同步成 功, 或者同步完成并完成了切换, 但是无法发送切换完成; 如果是 RLF, 说明所述 UE在目标小区发送切换完成命令成功 ,并可以在目标小区发起业 务后, 而发生的连接失败;

可选的,在所述 UE接收 MRO启动信令开启 MRO功能之前,所述 UE 可向所述源网元上报其是否支持 MRO功能, 这样, 所述源网元在获知所述 UE是否支持 MRO功能之后,即可指示支持 MRO功能的 UE开启 MRO功 能, 而并非向所有 UE指示开启 MRO功能, 使得 MRO功能的开启更具针 对性。 因而, 所述方法还可包括:

所述 UE根据所述测量控制信令或所述切换信令中的所述 MRO启动指 示, 开启 MRO功能。 其中, 所述 MRO启动指示可以为一个 MRO标志( MRO Flag ), 例如, 当所述 MRO标志的值为真(例如, True或 Enable等) 时, 表示指示 UE 开启 MRO功能。
在所述 UE开启 MRO功能后,为了节约系统资源,可在不需使用 MRO 功能时关闭 MRO功能。 因而, 可选的, 所述方法还可包括:
