Description

业务中断的処理方法及其装置 技术领域
本发明涉及通信技术领域, 尤其涉及一种业务中断的处理方法及相关装置。 背景技术
随着通信技术的发展,语音通话业务和视频业务等实时业务因其便捷性、实 时性已成为人们日常生活中必不可少的通信手段。然而,在实时业务的进行过程 中, 难免遇到因设备限制、 质量限制、设备故障或者其它原因, 包括有线或者无 线通信中的传输设备限制、无线通信中的无线信道质量下降, 而需要中断用户设 备正在进行的实时业务的情况, 降低了用户的主观感受和使用体验。
在当前的全球数字移动电话( Global System for Mobile, GSM )通信系统中, 语音通话业务主要因切换而中断,其中切换按其触发因素又可分为两大类:一是 基于质量因素的切换, 比如将用户设备从质量差的小区切换到质量好的小区;二 是基于容量因素的切换, 比如将用户设备从全速率信道切换到半速率信道, 以便 接入更多的用户设备。
在第二代移动通讯技术(2nd Generation, 2G ) 的 GSM系统中, 现有的切 换方式均属于硬切换, 即,用户设备在切换过程中首先需要从原小区的无线链路 上断开, 然后才能在新小区的无线链路上建立连接继续通话。 在切换过程中, 语 音数据会不可避免地丢失,且用户设备与基站的信令交互也需要占用语音数据的 传输带宽, 同样会造成语音数据的丢失。如果是在用户语音通话过程中产生的语 音数据丢下,则会带来通话用户主观听觉感受上带来明显的断续感以及平均意见 分 ( Mean Opinion Score, MOS ) 的下降。 发明内容

下面将结合本发明实施例中的附图, 对本发明实施例中的技术方案进行清 楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而不是全 部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳 动前提下所获得的所有其他实施例, 都属于本发明保护的范围。
请参见图 1 , 是本发明实施例提供的一种业务中断的处理方法的流程示意 图。本发明实施例中的实时业务主要包括对信息传输的即时性要求较高且对信息 传输的延迟和抖动较为敏感的业务, 主要包括但不限于: 语音通话、 视频点播 ( Video On Demand, VOD )、 网络电话( Voice Over Internet Protocol, VOIP )和 远程教学等业务。 具体的, 所述方法包括:
S101 : 在需要中断用户设备正在进行的实时业务的数据帧传输时, 检测端 若检测到所述实时业务的数据帧的数据帧等级满足预置的中断延迟条件,所述检 测端发送第一控制指令给中断执行端,以便于所述中断执行端收到所述第一控制 指令后延迟中断所述实时业务的数据帧的传输。
所述的第一控制指令为用于指示所述中断执行端延迟中断所述实时业务的 数据帧的传输的指令。
在所述 S101中, 实时业务的中断原因可以包括但不限于以下情况: 由于当 前服务的设备质量限制需要将业务切换到其他质量更优的设备上;或者, 出于业 务整体分配布局等原因需要将正在进行的业务切换到其他设备上继续进行; 或 者,由于设备出现故障需要将正在进行中的实时业务切换到其它能够提供正常服 务的设备上。
根据上述情况则可确定是否需要执行对所述实时业务的中断操作。而所述实 时业务的数据帧的数据帧等级则可以根据该实时业务的数据帧的强度等特征来 进行确定。数据帧等级可以根据需要设置为高等级的第一等级和低等级的第二等 级,通过判断数据帧等级是否为第一等级或第二等级来判断所述实时业务的数据 帧的数据帧等级是否满足预置的中断延迟条件。
若所述实时业务中数据帧的数据帧等级为第一等级,满足中断延迟条件,需 要延迟中断,向中断执行端发送第一控制指令,使所述实时业务的数据帧继续传 输, 直至实时业务的数据帧满足预设的中断触发条件后再执行中断操作。
而若所述实时业务的数据帧的数据帧等级为第二等级,则可以直接执行中断 操作。 具体的, 例如, 在所述 S101中, 若用户当前正在通话中, 根据语音数据帧 的振幅以及频率等参数确定为大能量人声时,显然该数据帧为重要数据帧,若中 断则会使得用户的通话中断。 而如果语音数据帧为小能量非人声,则基本可以确 定该数据帧不重要,则可直接发起中断,以切换到其他设备上进行所述实时业务, 此时不会中断不会影响用户的语音通话。
进一步的,也可以先根据中断的发起原因设置关于中断的优先级,如果需要 中断用户设备正在进行的实时业务的中断等级为预设的高优先级中断时,例如因 为当前承载实时业务的设备发生故障无法进行有效通信需要执行中断等高优先 级的中断时, 也可直接进行中断操作。 如果不为高优先级的中断, 则执行所述
S101。
S102: 在继续传输所述实时业务的数据帧的过程中, 所述检测端若检测到 所述实时业务的数据帧的数据帧等级满足预置的中断触发条件,则所述检测端发 送第二控制指令给所述中断执行端,以便于所述中断执行端收到所述第二控制指 令后中断所述实时业务。
具体的, 所述 S102中满足中断触发条件包括: 当继续传输所述实时业务的 数据帧的时长达到预设的时长阈值时,如从开始延迟中断开始计时的计时器计时 结束时, 满足中断触发条件, 此时需要发送第二控制指令给中断执行端;
或者当检测到继续传输的所述实时业务的数据帧出现至少一帧等级为所述 第二等级的数据帧时,满足中断触发条件,此时需要发送第二控制指令给中断执 行端;
或者判断继续传输所述实时业务的数据帧的时长是否达到预设的时长阈值; 若未到达所述时长阈值,进一步判断继续传输所述实时业务的数据帧的过程中是 否出现至少一帧等级为预设的第二等级的数据帧,若出现至少一帧等级为预设的 第二等级的数据帧,满足所述中断触发条件,此时需要发送第二控制指令给中断 执行端。
可根据计时器的计时来判断继续传输数据帧的时长是否到达预设的时长阈 值, 判断语音通话数据帧的数据帧等级的方法可以根据能量大小等方式进行确 认, 对应的第一等级和第二等级也可以根据能量大小设置, 大于某一能量值, 则 为第一等级, 否则为第二等级。 需要说明的是,在上述整个过程中,所述检测端和中断执行端可以均设置在 基站( Base Transceiver Station, BTS ) 中, 执行上述的对实时业务的数据帧的等 级判定、 中断延迟以及中断操作等步骤。 在其他实施例中, 所述检测端和中断执 行端也可以均设置在基站控制器(Base Station Controller, BSC )上, 执行对实 时业务的数据帧的等级判定、 中断延迟以及中断操作等步骤; 或者, 所述检测端 设置在 BSC中执行对实时业务的数据帧的等级判定等步骤, 而所述中断执行端 则设置在 BTS 中执行中断延迟以及中断操作等步骤; 或者所述检测端设置在 BTS 中执行对实时业务的数据帧的等级判定等步骤, 而所述中断执行端则设置 在 BSC中, 在 BTS和 BSC进行信息交互, BSC接收到 BTS发送的第一控制命 方式执行中断延迟以及中断操作等步骤。
本发明实施例通过识别需要中断的实时业务的数据帧的重要性,能够在需要 中断实时业务但实时业务传输的数据帧又处于重要数据帧时,延迟中断该实时业 务的数据帧的传输,重新选择中断时机,使得中断过程发生在非重要数据帧的位 置, 从而最大限度的降低中断过程对实时业务质量的负面影响。
请参见图 2,是本发明实施例提供的另一种业务中断的处理方法的流程示意 图。 本发明实施例的中断处理方法应用在语音通话、视频点播等实时业务中, 用 于确定中断时机以对这些实时业务进行中断处理, 首先, 在本发明实施例中, 所 述实时业务的数据帧的数据帧等级至少分为第一等级和第二等级;是否满足预置 的中断延迟条件是根据所述实时业务的数据帧的数据帧等级是否为第一等级或 者第二等级进行判断。 具体的, 本发明实施例所述的方法包括:
可选的, S201 : 所述检测端实时检测用户设备正在进行的所述实时业务的 数据帧的数据帧等级。
在所述 S201中, 检测端可对用户设备进行的如语音通话等实时业务进行实 时检测, 以便于在需要中断该实时业务时, 能够及时准确地进行数据帧等级的判 断。可以包括实时检测实时业务当前数据帧的帧等级, 以便于仅根据当前数据帧 确定是否延迟中断,或者包括实时检测实时业务当前数据帧的帧等级,并且记录 已经处理完毕的数据帧等级以便得到包括当前数据帧的连续两帧或者多帧的数 据帧等级,然后再根据包括当前数据帧的连续两帧或者多帧的帧等级确定是否延 迟中断。
语音通话业务等实时业务的数据帧的帧等级可根据该数据帧的能量大小、和 /或是否为用户发出的声音来进行确认, 其中, 判定是否为用户发出的声音则可 以根据该数据帧的频率进行确定。 例如, 可以根据数据帧为: 大能量人声、 小能 量人声、 大能量非人声、 小能量非人声划分数据帧等级为重要的第一等级, 以及 普通的第二等级等。
S202: 在需要中断所述用户设备正在进行的所述实时业务的数据帧传输时, 若当前数据帧的数据帧等级为所述第一等级或者所述实时业务已连续传输至少 两帧等级为所述第一等级的数据帧,则满足所述预置的中断延迟条件,所述检测 端发送所述第一控制指令给所述中断执行端。
即若当前的数据帧等级为预设的第一等级或者包括当前数据帧在内的连续 至少两个数据帧等级为第一等级,则满足预置的中断延迟条件,发送所述第一控 制指令给所述中断执行端以延迟中断, 使实时业务的数据帧继续传输。
实时业务的中断原因可以包括以下情况:由于当前服务的设备质量限制需要 将业务切换到其他质量更优的设备上;或者出于业务整体分配布局等原因需要将 正在进行的业务切换到其他设备上继续进行;或者由于设备出现故障需要将正在 进行中的实时业务切换到其它能够提供正常服务的设备上。
在检测数据帧的数据帧等级时,同时根据与当前数据帧连续的已经处理完毕 的数据帧的数据帧等级,可以较为准确地确定需要中断时的所述实时业务的数据 帧是否为用户正在通话等对应的重要数据帧。
检测端在所述 S201中一直检测实时业务的数据帧的等级, 在需要中断该实 时业务的数据帧的传输时,可以直接根据检测的结果判断是否延迟中断,还是直 可以设置在 BSC, 或者分别设置在 BTS和 BSC中执行相应的步骤, 本发明实施 例以检测端和中断执行端均设置在 BTS中实现来进行说明, 当然, 在其他的实 施例中, 所述业务中断的处理方法也可以在其它具有与 BTS相同或相似功能的 网络设备中实现, 本发明对此不做限定。
具体的,是否中断用户设备正在进行的实时业务的判断过程为:对于语音通 话业务,用户在通过其用户设备与其它用户通话时,为了保证语音通话的持续性 和通话质量,需要对语音通话业务进行中断处理, 以便于将本次通话业务从质量 差的小区切换到质量好的小区承载。 首先用户设备和 BTS分别测量收集无线信 道质量: 用户设备通过测量由 BTS发出的、 经过信道、 到达用户设备时的信号 质量变化情况, BTS 则测量相反方向的信号质量变化情况得到测量报告, 之后 用户设备和 BTS在预置的每个时间周期例如 480ms将测量报告上报给 BSC, 由 BSC 处理测量报告, 以根据处理结果和预置的切换判决算法决定当前时刻是否 需要触发切换, 即决定是否需要中断该用户设备的语音通话业务, 若是, 则通知 BTS进行是否立即中断的判决以及处理。
当 BSC通过切换算法判决生成切换命令(用于中断用户设备的语音通话业 务)并下发给 BTS时, 所述 BTS即确定需要中断用户设备正在进行的语音通话 业务。
检测到需要中断实时业务时, BTS执行下述步骤:
BTS通过其内部的检测端和中断执行端进行第一控制指令和第二控制指令 的传输完成延迟中断以及中断操作。 在 S201中实时检测用户设备正在进行的语 音通话业务的数据帧等级。 若 BTS确定所述语音通话业务的当前数据帧的数据 帧等级为所述第一等级,或者所述实时业务已连续传输至少两帧等级为所述第一 等级的数据帧, 说明当前正处于重要语音数据帧段。 此时, BTS需要对 BSC发 送的切换命令进行延迟, 即不中断用户设备正在进行的实时业务的数据帧的传 输, BTS 可以同时启动切换延迟计时器开始计时, 在延迟计时器计时过程中继 续传输所述语音通话业务的语音数据。
在需要中断用户设备正在进行的语音通话业务时, 若 BTS确定当前的所述 语音通话业务的语音数据帧的等级为第二等级、或者所述实时业务已连续传输至 少两帧等级为所述第二等级的数据帧,说明当前正处于非重要语音数据帧段,可 以中断, 则向用户设备发起切换流程, 使用户设备完成切换。
S203 : 在继续传输所述实时业务的数据帧的过程中, 所述检测端若检测到 所述实时业务的数据帧的数据帧等级满足预置的中断触发条件,则所述检测端发 送第二控制指令给所述中断执行端,以便于所述中断执行端收到所述第二控制指 令后中断所述实时业务。
具体的, 所述 S203中满足中断触发条件包括: 当继续传输所述实时业务的 数据帧的时长达到预设的时长阈值时,满足所述中断触发条件,需要发送第二控 制指令给所述中断执行端;
或者所述检测端检测到继续传输的所述实时业务的数据帧出现至少一帧等 级为所述第二等级的数据帧时,满足所述中断触发条件,需要发送第二控制指令 给所述中断执行端;
或者判断继续传输的所述实时业务的数据帧的时长是否达到所述预设的时 长阈值;若未到达所述时长阈值,进一步判断继续传输所述实时业务的数据帧的 过程中是否出现至少一帧等级为所述第二等级的数据帧;若出现至少一帧等级为 所述第二等级的数据帧,满足所述中断触发条件,需要发送第二控制指令给所述 中断执行端。
BTS 可根据计时器的计时来判断继续传输语音数据的时长是否到达预设的 时长阈值, 在继续传输语音通话业务的过程中, BTS 判断语音通话业务的数据 帧等级的方法同样是根据数据帧的能量等特征进行识别。
本发明实施例通过识别需要中断的实时业务的数据帧,能够在需要中断实时 业务但实时业务当前帧为重要数据帧时,延迟中断实时业务,重新选择中断时机, 使得中断过程发生在非重要数据帧的位置,从而最大限度的降低中断过程对实时 业务质量的负面影响。
再请参见图 3 ,是本发明实施例的再一种实时业务中断的处理方法的流程示 意图,与上述图 2对应的实施例的不同之处在于,本发明实施例是在确定需要中 断用户设备当前正在进行的实时业务时,触发业务中断的流程,并不是实时检测 用户设备当前正在进行的实时业务的数据帧等级。具体的,本实施例的所述方法 包括:
S301 : 在需要中断所述用户设备正在进行的所述实时业务的数据帧传输时, 所述检测端检测所述用户设备当前正在进行的所述实时业务传输的数据帧的数 据帧等级。
语音通话业务等实时业务的数据帧的数据帧等级可根据该数据帧的能量大 小、 和 /或是否为用户发出的声音来进行确认, 其中, 判定是否为用户发出的声 音则可以根据该数据帧的频率进行确定。例如,可以根据数据帧为:大能量人声、 小能量人声、 大能量非人声、 小能量非人声划分数据帧等级为重要的第一等级, 以及普通的第二等级等。
实时业务的中断原因可以包括以下情况:由于当前服务的设备质量限制需要 将业务切换到其他质量更优的设备上;或者出于业务整体分配布局等原因需要将 正在进行的业务切换到其他设备上继续进行;或者由于设备出现故障需要将正在 进行中的实时业务切换到其它能够提供正常服务的设备上。
根据上述情况即可确定是否执行对所述实时业务的中断操作。
S302: 若正在进行的所述实时业务传输的数据帧的数据帧等级为预设的所 述第一等级,则满足所述预置的中断延迟条件,所述检测端发送所述第一控制指 令给所述中断执行端。
S303 : 在继续传输所述实时业务的数据帧的过程中, 所述检测端若检测到 所述实时业务的数据帧的数据帧等级满足预置的中断触发条件,则所述检测端发 送第二控制指令给所述中断执行端,以便于所述中断执行端收到所述第二控制指 令后中断所述实时业务。
具体的, 所述 S303中满足中断触发条件包括: 当继续传输所述实时业务的 数据帧的时长达到预设的时长阈值时,满足所述中断触发条件,需要发送第二控 制指令给所述中断执行端;
或者包括:检测到继续传输的所述实时业务的数据帧出现至少一帧等级为所 述第二等级的数据帧时,满足所述中断触发条件,需要发送第二控制指令给所述 中断执行端;
或者包括:判断继续传输的所述实时业务的数据帧的时长是否达到所述预设 的时长阈值;若未到达所述时长阈值,进一步判断继续传输所述实时业务的数据 帧的过程中是否出现至少一帧等级为所述第二等级的数据帧;若出现至少一帧等 级为所述第二等级的数据帧,满足所述中断触发条件,需要发送第二控制指令给 所述中断执行端。 能, 当然也可以设置在 BSC中实现相应的功能, 也可以分别设置在 BTS和 BSC 中实现相应的功能, 本发明实施例以检测端和中断执行端在 BTS中实现来进行 说明, 当然, 在其他的实施例中, 所述业务中断的处理方法也可以在其它具有与 BTS相同或相似功能的网络设备中实现, 本发明对此不做限定。 具体的,是否中断用户设备正在进行的实时业务的判断过程为: 用户在通过 其用户设备与其它用户通话时,为了保证语音通话的持续性和通话质量,需要对 语音通话业务进行中断处理,以便于将本次通话业务从质量差的小区切换到质量 好的小区 7 载。 首先用户设备和 BTS分别测量收集无线信道质量: 用户设备测 量由 BTS发出、 经过信道、 到达用户设备时的信号质量变化情况, BTS测量相 反方向的信号质量变化情况得到测量报告, 之后用户设备和 BTS在预置的每个 时间周期例如 480ms将测量报告上报给 BSC, 由 BSC处理测量报告, 以根据处 理结果和预置的切换判决算法决定当前时刻是否需要触发切换。即决定是否需要 中断该用户设备的语音通话业务, 若是, 则通知 BTS进行是否立即中断的判决 以及处理。
BSC 通过切换算法判决生成切换命令(中断用户设备的语音通话业务的命 令)并下发给 BTS, 当 BTS接收到切换命令时, 确定需要中断用户设备正在进 行的语音通话业务, BTS 识别所述语音通话业务的语音数据当前语音数据帧的 等级。 在本发明实施例中, BTS只能检测在接收到 BSC下发的切换命令时的语 音通话业务的数据帧等级。
检测到需要中断实时业务时, BTS执行下述步骤:
BTS通过其内部的检测端和中断执行端之间进行第一控制指令和第二控制 指令的传输完成延迟中断以及中断操作。 在 S302中, BTS检测识别出所述语音 通话业务当前语音数据帧的等级为第一等级, 说明当前正处于重要语音数据帧 段。 此时, BTS 需要延迟中断, 以继续用户设备正在进行的实时业务的数据帧 的传输, BTS 可以启动计时器开始计时, 在计时过程中继续传输所述语音通话 业务的语音数据。
而若 BTS识别出所述语音通话业务的语音数据当前语音数据帧的等级为第 二等级,说明当前正处于非重要语音数据帧段,可以进行中断所述用户设备的当 前正在进行的实时业务的数据帧的传输,将切换命令发送给用户设备,使用户设 备完成切换。
本发明实施例通过识别需要中断的实时业务当前数据帧的等级,能够在需要 中断实时业务但实时业务当前帧为重要数据帧时,延迟直中断该实时业务的数据 帧的传输, 重新选择中断时机, 使得中断过程发生在非重要数据帧的位置, 从而 最大限度的降低中断过程对实时业务质量的负面影响。
请参见图 4,是本发明实施例提供的再一种实时业务中断的处理方法的流程 示意图, 本方法实施例中的所述实时业务包括语音通话、视频点播、 网络电话以 及远程教学等业务。本发明实施例的所述实时业务的数据帧的数据帧等级包括第 一等级和第二等级,是否满足预置的中断延迟条件是根据所述实时业务的数据帧 的数据帧等级是否为第一等级或者第二等级进行判断。在需要中断用户设备正在 进行的实时业务之前,还包括为各类中断预设优先级。本发明实施例的所述方法 包括:
可选地, S401 : 检测端判断对所述用户设备正在进行的实时业务的中断的 优先级;
具体的,在需要中断用户设备正在进行的实时业务之前,还包括为各类中断 预设优先级, 其中, 包括预设高优先级的中断, 以及低优先级的中断; 如果需要 中断用户设备正在进行的实时业务的中断等级为预设的高优先级中断时,例如因 为当前承载实时业务的设备发生故障无法进行有效通信需要执行中断等高优先 级的中断时, 也可直接进行中断操作, 即执行下述 S402 , 否则, 执行下述 S403。
可选地, S402: 若所述中断为预设的高优先级, 检测端发送第二控制指令 给所述中断执行端。
针对一些优先级为高优先级的中断,例如当前承载实时业务的设备发生故障 无法进行有效通信需要执行中断时,则需要直接发送第二控制指令以快速中断所 述实时业务以完成切换。检测端中可以维护一个优先级映射表,为由于各种原因 引起的中断设置并记录对应的优先级,具体可设置两个优先级即高优先级和低优 先级, 当中断的优先级为高优先级时, 直接向用户设备发送中断命令, 为低优先 级时, 则根据当前数据帧的数据帧等级确定是否直接执行中断还是延迟中断。
可选地, S403 : 检测端检测所述实时业务的数据帧的数据帧等级。
其中, 当所述实时业务为语音通话业务时,检测所述实时业务当前数据帧的 数据帧等级, 包括: 提取所述语音通话业务中当前语音数据帧的语音编码参数; 将所述语音编码参数与预设的特征条件进行比较,若所述语音编码参数符合所述 特征条件时, 则所述语音数据帧的等级为第一等级, 否则, 所述语音数据帧的等 级为第二等级。 S404: 检测端若检测到所述实时业务的数据帧的数据帧等级满足预置的中 断延迟条件,所述检测端发送第一控制指令给中断执行端,以便于所述中断执行 端收到所述第一控制指令后延迟中断所述实时业务的数据帧的传输。
S405: 在继续传输所述实时业务的数据帧的过程中, 所述检测端若检测到 所述实时业务的数据帧的数据帧等级满足预置的中断触发条件,则所述检测端发 送第二控制指令给所述中断执行端,以便于所述中断执行端收到所述第二控制指 令后中断所述实时业务。
即在继续传输过程中,传输数据满足预置的中断触发条件时,向所述用户设 备发送中断命令, 以中断所述实时业务, 执行切换等操作。
可选地, S406: 若检测到所述实时业务当前传输的数据帧的数据帧等级为 所述第二等级,或所述实时业务连续至少两个数据帧等级为所述第二等级,则满 足预置的中断延迟条件, 则所述检测端发送所述第二控制指令给所述中断执行 端。
即在当前数据帧等级或者连续至少两个数据帧等级为不重要的普通帧时,例 如能量小的数据帧时, 则直接中断该实时业务, 以进行切换等操作。
具体的, 请参见图 5 , 是本发明实施例的在继续传输实时业务的数据帧时的 中断处理方法的其中一种流程示意图, 所述方法包括:
S3001 : 检测端判断所述实时业务的数据帧的继续传输时长是否达到预设的 时长阈值;
在所述检测端发送第二控制指令给所述中断执行端之前,还包括预设时长阈 值的步骤, 以便于执行所述 S3001。在所述 S3001中可通过计时器计时方式判断 继续传输的时长是否达到计时器所设的时长阈值,即在接收到切换命令等需要中 断用户设备的实时业务, 而确定需要延迟中断、继续传输所述实时业务时开始计 时。
S3002: 当所述数据帧的继续传输时长达到所述预设的时长阈值时, 满足所 述中断触发条件, 所述检测端发送所述第二控制指令给所述中断执行端。
具体的, 请参见图 6, 是本发明实施例的在继续传输实时业务的数据帧时的 中断处理方法的其中另一种方法流程示意图, 所述方法包括:
S3011 : 检测端检测继续传输的所述实时业务的数据帧是否出现至少一帧等 级为预设的第二等级的数据帧;
具体的,可以为检测到一帧非重要帧就触发后续的中断;或者为检测到一定 数量的连续非重要帧才触发后续的中断。
S3012: 当检测到继续传输的所述实时业务的数据帧出现至少一帧等级为预 设的第二等级的数据帧时,满足所述中断触发条件,所述检测端发送所述第二控 制指令给所述中断执行端。
具体的, 请参见图 7, 是本发明实施例的在继续传输实时业务的数据帧时的 中断处理方法的其中再一种流程示意图, 所述方法包括:
S3021 : 检测端判断继续传输所述实时业务的数据帧的时长是否达到预设的 时长阈值;在所述检测端发送第二控制指令给所述中断执行端之前,还包括预设 时长阈值的步骤, 以便于执行所述 S3021。在所述 S3021中同样可以通过计时器 计时的方式判断。
S3022: 若未到达所述时长阈值, 检测端进一步判断继续传输所述实时业务 的数据帧的过程中是否出现至少一帧等级为预设的第二等级的数据帧; 具体的, 可以检测到一帧非重要帧就触发后续的中断;或者为检测到一定数量的连续非重 要帧才触发后续的中断。
S3023 : 若出现至少一帧等级为预设的第二等级的数据帧, 满足所述中断触 发条件, 所述检测端发送所述第二控制指令给所述中断执行端。
再请参见图 8 ,是本发明实施例的对语音通话业务的数据帧等级判定的其中 一种方法流程示意图; 所述方法包括:
S3031 : 检测端提取所述语音通话业务中当前语音数据帧的语音编码参数; 所述语音编码参数包括频率参数和 /或能量参数, 其中, 所述频率参数包括线谱 频率、 自适应码本和固定码本中的一个或多个,所述能量参数包括自适应码本增 益和 /或固定码本增益。
其中,所述线谱频率、 自适应码本和固定码本中的一个或多个主要用于有效 地区分人声和非人声,所述线谱频率表征气流经过声带后在整个口腔内共振的频 率共振峰, 而所述自适应码本则表征人声带振动频率。 而所述自适应码本增益和 /或固定码本增益则主要用于标识语音能量值。
S3032: 检测端将所述语音编码参数与预设的特征条件进行比较, 若所述语 音编码参数符合所述特征条件时, 则所述语音数据帧的等级为第一等级, 否则, 所述语音数据帧的等级为第二等级。
所述特征条件可以为一个能量和 /或频率值判决门限, 根据语音通话业务中 当前语音数据帧的上述语音编码各类参数所表征的能量和 /或频率与预设的能量 和 /或频率值判决门限进行比较, 以判定所述语音数据帧的等级为第一等级还是 为第二等级。
具体的,在移动通信系统中,语音通话业务的语音数据经过语音编码压缩以 后, 以 20ms—帧的语音数据帧形式在无线链路中传输, 当前 GSM系统中的语 音编码算法都是基于线性预测原理, 压缩编码后的语音编码参数基本可分为五 类:线谱频率( Linear Spectrum frequency, LSF )、自适应码本( Adaptive Codebook, AC )、 自适应码本增益 (Adaptive Codebook Gain, ACG )、 固定码本(Fixed Codebook, FC )、 固定码本增益( Fixed Codebook Gain, FCG )。 该 5类语音编 码参数分别表征这 20ms—帧的语音数据帧中语音的不同频率和能量特征, 经过 重新解码这 5类语音编码参数, 能够重新得到原始的语音波形。从语音波形上比 较容易识别语音的重要性,基本根据能量即可大致区分,但由于解码参数需要一 定的运算量,为了识别重要性而对每一帧语音数据帧都进行解码则成本太高,故 本发明实施例主要是基于语音编码参数进行语音通话数据帧的数据帧等级的快 速识别, 而不用进行语音编码参数解码。
所述语音编码参数包括频率参数和 /或能量参数。
所述频率参数包括线谱频率和 /或自适应码本, 所述能量参数包括自适应码 本增益和 /或固定码本增益。
具体的, LSF和 AC这两类参数能有效的区分人声和非人声, 其中 AC表征 人声带振动频率, 而 LSF表征气流经过声带后在整个口腔内共振的频率共振峰, 当人声出现时, LSF会变得不稳定(值变化较为剧烈)、 而 AC则会相对稳定(值 变化较小); 而当人声消失时, 则 AC会变得不稳定, 而 LSF会相对稳定。
而 ACG和 FCG这两类参数主要表征语音能量, 能量较大时重要帧的概率 较高, 能量较小时则重要性概率较低。
BTS提取当前语音数据帧的 LSF和 AC中的任意一个或两个, 并提取 ACG 和 FCG中的任意一个或两个。 假设在本发明实施例中, BTS提取了当前语音数 据帧的 LSF、 AC、 ACG和 FCG这四类语音编码参数。
BTS将所述语音编码参数与预设的特征条件进行比较, 特征条件是针对不 同的语音编码参数分别预设的, BTS将上述四类语音编码参数分别与其预设的 特征条件进行比较, 得到比较结果, 经过 4类参数的分别比较后, 再进行组合判 断, 即可判断出当前语音数据帧是表示大能量人声, 还是表示小能量人声, 还是 表示大能量非人声,还是表示小能量非人声,进一步能确定出当前语音数据帧的 等级,若将语音数据帧分为两级,则表示小能量非人声的语音数据帧为第二等级, 其余为第一等级。则对于表示小能量非人声的语音数据帧,则就是切换影响较小 的语音通话业务部分。
进一步具体的,本发明还提供了一种计算机存储介质,所述计算机存储介质 存储有程序, 该程序执行时包括图 1到图 8任一实施例的方法步骤。
通过上述实施例的描述可知, 本发明具有以下优点:
本发明实施例通过识别需要中断的实时业务的数据帧的等级,能够在需要中 断实时业务但实时业务当前帧为重要数据帧时,延迟中断所述实时业务,重新选 择中断时机,使得中断过程发生在非重要数据帧的位置,从而最大限度的降低中 断过程对实时业务质量的负面影响。
下面以中断执行端对本发明实施例业务中断的处理方法进行详细描述。 图 9是本发明实施例的再一种业务中断的处理方法的流程示意图, 具体的, 本发明实施例的所述方法包括:
S501 : 中断执行端接收检测端发送的第一控制指令或第二或者指令; 所述第一控制指令为在需要中断用户设备正在进行的实时业务的数据帧传 输时,所述检测端检测到所述实时业务的数据帧的数据帧等级满足预置的中断延 迟条件后由所述检测端发送给所述中断执行端;
所述第二控制指令为在继续传输所述实时业务的数据帧的过程中,所述检测 端检测到所述实时业务的数据帧的数据帧等级满足预置的中断触发条件后由所 述检测端发送给所述中断执行端;
S502: 所述中断执行端收到所述第一控制指令后延迟中断所述实时业务; S503 : 所述中断执行端收到所述第二控制指令后中断所述用户设备正在进 行的所述实时业务。 所述检测端和中断执行端可以均设置在 BTS中, 执行对实时业务的数据帧 的等级判定、 中断延迟以及中断操作等步骤。 在其他实施例中, 所述检测端和中 断执行端也可以均设置在 BSC上, 执行对实时业务的数据帧的等级判定、 中断 延迟以及中断操作等步骤; 或者, 所述检测端设置在 BSC中执行对实时业务的 数据帧的等级判定等步骤, 而所述中断执行端则设置在 BTS中执行中断延迟以 及中断操作等步骤; 或者所述检测端设置在 BTS中执行对实时业务的数据帧的 等级判定等步骤, 而所述中断执行端则设置在 BSC中, 通过 BTS和 BSC之间 的交互, BSC接收到第一控制指令或者第二控制指令后, 由 BSC通过发送延迟 其中, 当所述中断执行端设置在基站控制器 BSC中时,所述 S502具体可以 包括:所述中断执行端收到所述第一控制指令后向基站 BTS发送延迟中断命令, 以使所述基站 BTS延迟中断该基站 BTS服务的所述用户设备正在进行的所述实 时业务; 所述 S503具体可以包括: 所述中断执行端收到所述第二控制指令后向 基站 BTS发送中断指令, 以使所述基站 BTS中断该基站 BTS服务的所述用户 设备正在进行的所述实时业务。
也就是说, 当 BSC作为中断执行端执行中断延迟或者中断操作时, BSC可 以通过发指令给 BTS, 以控制 BTS来完成实时业务的延迟中断和中断操作。
本发明实施例通过识别需要中断的实时业务的数据帧的等级,能够在需要中 断实时业务但实时业务当前帧为重要数据帧时,延迟中断所述实时业务的数据帧 的传输, 重新选择中断时机, 使得中断过程发生在非重要数据帧的位置, 从而最 大限度的降低中断过程对实时业务质量的负面影响。
下面对本发明实施例的相关装置进行详细说明。
请参见图 10,是本发明实施例提供的一种业务中断的检测端的结构示意图, 所述检测端包括: 处理模块 11、 中断模块 12, 其中:
处理模块 11 , 用于在需要中断用户设备正在进行的实时业务的数据帧传输 时,若检测到所述实时业务的数据帧的数据帧等级满足预置的中断延迟条件,发 送第一控制指令给中断执行端,以便于所述中断执行端收到所述第一控制指令后 延迟中断所述实时业务。
实时业务的中断原因可以包括以下情况:由于当前服务的设备质量限制需要 将业务切换到其他质量更优的设备上;或者, 出于业务整体分配布局等原因需要 将正在进行的业务切换到其他设备上继续进行;或者, 由于设备出现故障需要将 正在进行中的实时业务切换到其它能够提供正常服务的设备上。
在上述情况下确定需要中断所述实时业务后, 所述处理模块 11在所述实时 业务中数据帧的数据帧等级为第一等级,向中断执行端发送第一控制命令以延迟 发起中断操作,继续传输所述数据帧。所述实时业务数据帧的数据帧等级可以在 需要中断所述实时业务之前进行确认,也可以在需要中断所述实时业务之后进行 确认。
中断模块 12, 用于在继续传输所述实时业务的数据帧的过程中, 若检测到 所述实时业务的数据帧的数据帧等级满足预置的中断触发条件,则发送第二控制 指令给所述中断执行端,以便于所述中断执行端收到所述第二控制指令后中断所 述实时业务。
并且, 所述中断模块 12还用于检测到继续传输的所述实时业务的数据帧出 现至少一帧等级为所述第二等级的数据帧时,满足所述中断触发条件,发送所述 第二控制指令给所述中断执行端。
所述第一控制指令用于指示中断执行端延迟中断,而第二控制指令则指示中 断执行端执行中断。
所述中断模块 12判定是否满足中断触发条件, 可通过判断: 继续传输所述 实时业务的数据帧的时长到达预设的时长阈值时,如计时器计时完成时,满足中 断触发条件;或者, 当检测到所述数据帧的继续传输过程中连续出现至少两帧数 据帧等级为第二等级的数据帧时, 满足中断触发条件; 或者, 判断所述数据帧的 继续传输时长是否达到所述时长阈值;若未到达所述时长阈值,则在所述时长阈 值内,当检测到所述数据帧的继续传输过程中连续出现至少两帧数据帧等级为第 二等级的数据帧时, 满足所述中断触发条件。
具体的,本发明实施例中的实时业务主要包括对信息传输的即时性要求较高 且对信息传输的延迟和抖动较为敏感的业务, 主要包括但不限于: 语音通话、视 频点播、 网络电话和远程教学。
所述检测端和中断执行端可以均设置在 BTS中。 在其他实施例中, 所述检 测端和中断执行端也可以均设置在 BSC上; 或者, 所述检测端设置在 BSC, 而 所述中断执行端则设置在 BTS中; 或者所述检测端设置在 BTS中, 而所述中断 执行端则设置在 BSC中, 通过 BTS与 BSC之间进行交互, 在 BSC接收到第一 控制命令或者第二控制命令后, 由 BSC通过发送延迟中断命令或者中断命令给 BTS的方式执行中断延迟以及中断操作等。
下面以实时业务为语音通话业务、数据帧为语音数据、数据帧为语音数据帧、 中断命令为切换命令作为一种示例, 来说明本发明实施例的技术方案。
同样, 确定是否确定中断用户设备正在进行的实时业务的数据帧传输包括: 假设某一用户设备在与其它用户设备的通话过程中,为了保证语音通话的持 续性和通话质量,需要对语音通话业务进行中断处理,将该用户设备从质量差的 小区切换到质量好的小区。则首先用户设备和 BTS分别测量收集两个方向上的无 线信道质量: 用户设备测量由 BTS发出、 经过信道、 到达用户设备时的信号质量 变化情况, BTS测量相反方向的信号质量变化情况, 之后用户设备和基站以一定 周期, 如每 480ms ( millisecond, 毫秒)将测量报告上报一次给 BSC , 由 BSC处 理测量报告,以根据处理结果和预置的切换判决算法决定当前时刻是否需要触发 切换。 BSC通过切换算法判决生成切换命令并下发给 BTS , 即决定是否需要中断 该用户设备的语音通话业务, 若是, 则通知 BTS进行是否立即中断的判决以及处 理, 当 BTS接收到切换命令时, 也即当需要中断用户设备正在进行的语音通话业 务时。
具体的,在一段语音中,丢失不同的语音数据帧对用户主观感受的影响是不 同的。 例如, 在用户对话的间隙本身就没有话音, 这时如果丢掉了一些普通语音 数据帧,这时的语音数据帧包含的主要是一些背景噪声,对用户主观感受的影响 并不明显,但如果在用户正在通话时丢失了语音数据帧,就会造成语句的丢失或 者可懂性变差,这时对用户主观感受的影响就会非常明显。根据对用户主观感受 的影响不同,可以将语音数据帧分成不同的等级, 比如分为第一等级和第二等级 两等, 也可以分为三等, 四等等更多等级, 具体可以基于能量、 频率、 振幅等进 行区别划分。
本发明实施例以将语音数据帧分为两个等级为例进行说明,其中第一等级表 明语音数据帧为携带了人声的重要语音数据帧,而第二等级表明语音数据帧为携 带了背景噪声等非人声的非重要语音数据帧。等级为第一等级的重要语音数据帧 的丢失会造成主观感受的明显下降,而等级为第二等级的非重要语音数据帧的丢 失对主观感受的影响较小。 其它情况可以同理类推, 在此不赘述。
若所述语音通话业务的语音数据的等级为第二等级,说明当前正处于非重要 语音数据帧段, 可以进行切换, 那么所述中断模块 12则可直接发送第二控制命 令给中断执行端。
而若所述语音通话业务的语音数据当前语音数据帧的等级为第一等级,说明 当前正处于重要语音数据帧段。 所述处理模块 11进行延迟处理, 发送第一控制 命令给中断执行端以延迟中断, 所述处理模块 11还可以启动切换延迟计时器开 始计时, 所述语音数据继续传输, 而所述中断模块 12则在所述语音数据的继续 传输过程中判断是否满足预置的中断触发条件。
进一步可选的,所述实时业务的数据帧的数据帧等级至少可以分为第一等级 和第二等级;是否满足预置的中断延迟条件则可以根据所述实时业务的数据帧的 数据帧等级是否为第一等级或第二等级进行判断。
在本发明实施例中,所述检测端还可以通过第一预置模块存储预设的时长阈 值; 所述中断模块 12具体用于在检测到继续传输的所述实时业务的数据帧的时 长达到所述预设的时长阈值时,满足所述中断触发条件,发送所述第二控制指令 给所述中断执行端。 或者:
所述中断模块 12具体用于当检测到继续传输的所述实时业务的数据帧出现 至少一帧等级为所述第二等级的数据帧时,满足所述中断触发条件,发送所述第 二控制指令给所述中断执行端。 或者:

所述判断单元,用于判断继续传输的所述实时业务的数据帧的时长是否达到 所述预设的时长阈值;若未到达所述时长阈值,进一步判断继续传输所述实时业 务的数据帧的过程中是否出现至少一帧等级为所述第二等级的数据帧;
所述中断单元,用于若出现至少一帧等级为所述第二等级的数据帧,满足所 述中断触发条件, 发送所述第二控制指令给所述中断执行端。
进一步具体的, 请参见图 11 , 是图 10的业务中断的处理装置中的处理模块 11的其中一种具体结构示意图, 所述处理模块 11包括: 检测单元 111 , 用于实时检测用户设备正在进行的所述实时业务的数据帧的 数据帧等级;
第一判断单元 112, 用于判断是否需要中断用户设备正在进行的实时业务; 第一处理单元 113 ,用于在需要中断所述用户设备正在进行的所述实时业务 的数据帧传输时,若当前数据帧的数据帧等级为所述第一等级或者所述实时业务 已连续传输至少两帧等级为所述第一等级的数据帧,则满足所述预置的中断延迟 条件, 发送所述第一控制指令给所述中断执行端。
即所述检测单元 111 一直检测用户设备进行实时业务时每一个数据帧的数 据帧等级。
所述第一判断单元 112 可以在接收到其他设备发送的例如切换命令等要求 中断所述用户设备的实时业务命令时,确定需要中断用户设备正在进行的实时业 务,也可以为直接根据上述所提出的几种需要中断实时业务的情况判断确定是否 需要中断所述用户设备的实时业务。
所述第一处理单元 113则可以在所述数据帧的数据帧等级为第一等级时,控 制延迟执行中断操作, 继续传输所述数据帧。
进一步的, 再请参见图 12, 是图 10的业务中断的处理装置中的处理模块 1 的其中另一种具体结构示意图, 所述处理模块 1包括:
第二判断单元 114, 用于判断是否需要中断用户设备正在进行的实时业务; 识别单元 115 ,用于在需要中断所述用户设备正在进行的所述实时业务的数 据帧传输时,检测所述用户设备当前正在进行的所述实时业务传输的数据帧的数 据帧等级;
第二处理单元 116,用于若所正在进行的所述实时业务传输的数据帧的数据 帧等级为预设的所述第一等级,则满足所述预置的中断延迟条件,发送所述第一 控制指令给所述中断执行端。
本发明实施例中, 所述处理模块 11先通过所述第二判断单元 114确定是否 接收到中断用户设备的实时业务的命令,如接收到相应的命令,再通过所述识别 单元 115以及所述第二处理单元 116完成数据帧的等级的识别以及处理。
同样,所述第二判断 114可以在接收到其他设备发送的例如切换命令等要求 中断所述用户设备的实时业务命令时,确定需要中断用户设备正在进行的实时业 务 ,也可以直接根据上述所提出的几种需要中断实时业务的情况判断确定是否需 要中断所述用户设备的实时业务。

所述通知模块 15则用于若所述中断不为预设的高优先级, 通知所述处理模 块 11。
所述处理模块 11具体用于在所述判断模块 14判断结果为所述中断为预设的 低优先级时,检测所述实时业务的数据帧等级以执行若所述实时业务的数据帧等 级满足预置的中断延迟条件, 则延迟中断, 继续传输所述实时业务的数据帧; 或者用于通知所述中断模块执行若所述实时业务当前数据帧等级为预设的 第二等级、或者所述实时业务在预设时间阈值范围内已连续出现至少两次等级为 第二等级的数据帧, 则中断所述用户设备正在进行的所述实时业务。
所述中断模块 12 还用于当继续传输所述数据帧满足预置的中断触发条件 时, 执行对所述用户设备正在进行的实时业务的中断操作。
针对一些优先级为高优先级的中断,例如当前承载实时业务的设备发生故障 无法进行有效通信需要执行中断时, 则需要直接发送中断命令以快速进行切换。 可以维护一个优先级映射表,针对由于各种原因引起的中断设置记录对应的优先 级, 具体可设置两个优先级即高优先级和低优先级, 当所述判断模块 14根据所 述优先级映射表判断当前中断的优先级为高优先级时,则直接通过所述中断模块 12执行中断操作, 向所述用户设备发送中断命令, 为低优先级时, 则通知所述 处理模块 11以根据实时业务的数据帧进行相应处理,以及所述中断模块 12判断 确定继续传输所述实时业务的数据帧是否满足预置的中断触发条件,并在满足中 断触发条件时, 执行对所述用户设备正在进行的实时业务的中断操作。
进一步的, 再请参见图 13 , 对于语言通话业务, 本发明实施例的所述业务 中断的处理装置还可以包括: 提取模块 6, 比较模块 7。
提取模块 6, 用于当所述实时业务为语音通话业务时, 提取所述语音通话业 务中当前语音数据帧的语音编码参数; 所述语音编码参数包括频率参数和 /或能 量参数, 其中, 所述频率参数包括线谱频率、 自适应码本和固定码本中的一个或 多个, 所述能量参数包括自适应码本增益和 /或固定码本增益。

比较模块 7, 用于将所述语音编码参数与预设的特征条件进行比较, 若所述 语音编码参数符合所述特征条件时,则所述语音数据帧的等级为第一等级,否则, 所述语音数据帧的等级为第二等级。
所述特征条件可以为一个能量和 /或频率值判决门限, 根据语音通话业务中 当前语音数据帧的上述语音编码各类参数所表征的能量和 /或频率与预设的能量 和 /或频率值判决门限进行比较, 以判定所述语音数据帧的等级为第一等级还是 为第二等级。
具体的,在移动通信系统中,语音通话业务的语音数据经过语音编码压缩以 后, 以 20ms—帧的语音数据帧形式在无线链路中传输, 当前 GSM系统中的语 音编码算法都是基于线性预测原理, 压缩编码后的语音编码参数基本可分为五 类: LSF、 AC、 ACG、 FC、 FCG。 该 5类语音编码参数分别表征这 20ms—帧 的语音数据帧中语音的不同频率和能量特征, 经过重新解码这 5 类语音编码参 数, 能够重新得到原始的语音波形。 从语音波形上比较容易识别语音的重要性, 基本根据能量即可大致区分,但由于解码参数需要一定的运算量,为了识别重要 性而对每一帧语音数据帧都进行解码则成本太高,故本发明实施例主要是基于语 音编码参数进行语音通话的数据帧的数据帧等级的快速识别,而不用进行语音编 码参数解码。 所述语音编码参数包括频率参数和 /或能量参数。
所述频率参数包括线谱频率和 /或自适应码本, 所述能量参数包括自适应码 本增益和 /或固定码本增益。
具体的, LSF和 AC这两类参数能有效的区分人声和非人声, 其中 AC表征 人声带振动频率, 而 LSF表征气流经过声带后在整个口腔内共振的频率共振峰, 当人声出现时, LSF会变得不稳定(值变化较为剧烈)、 而 AC则会相对稳定(值 变化较小); 而当人声消失时, 则 AC会变得不稳定, 而 LSF会相对稳定。
而 ACG和 FCG这两类参数主要表征语音能量, 能量较大时重要帧的概率 较高, 能量较小时则重要性概率较低。
BTS提取当前语音数据帧的 LSF和 AC中的任意一个或两个, 并提取 ACG 和 FCG中的任意一个或两个。 假设在本发明实施例中, BTS提取了当前语音数 据帧的 LSF、 AC、 ACG和 FCG这四类语音编码参数。
BTS将所述语音编码参数与预设的特征条件进行比较, 特征条件是针对不 同的语音编码参数分别预设的, BTS将上述四类语音编码参数分别与其预设的 特征条件进行比较, 得到比较结果, 经过 4类参数的分别比较后, 再进行组合判 断, 即可判断出当前语音数据帧是表示大能量人声, 还是表示小能量人声,还是 表示大能量非人声,还是表示小能量非人声,进一步能确定出当前语音数据帧的 等级,若将语音数据帧分为两级,则表示小能量非人声的语音数据帧为第二等级, 其余为第一等级。则对于表示小能量非人声的语音数据帧,则就是切换影响较小 的语音通话业务部分。
通过上述实施例的描述可知, 本发明具有以下优点:
本发明实施例通过识别需要中断的实时业务当前数据帧的等级,能够在需要 中断实时业务但实时业务当前帧为重要数据帧时,延迟中断所述实时业务的数据 帧的传输, 重新选择中断时机,使得中断过程发生在非重要数据帧的位置, 从而 最大限度的降低中断过程对实时业务质量的负面影响。
