Description

一种下行信令的传输方法、 系统及装置 技术领域
本发明涉及第三代移动通信技术领域, 尤其涉及一种下行信令的传输 方法、 系统及装置。 背景技术
在包括时分同步码分多址 ( Time Division-Synchronous Code Division Multiple Access, TD-SCDMA )系统的第三代移动通信( 3rd-generation, 3G ) 系统中, 无线网络控制器( Radio Network Controller, RNC )是 3G无线网 络中的一个关键网元, RNC可以提供移动性管理、 呼叫处理、 链接管理和 切换机制等服务, 同时, RNC还具有管理用于传输用户数据的无线接入载 波、 管理和优化无线网络资源、 移动性控制和无线链路维护等功能。
RNC中包括无线网络层控制面( Radio Network Link Controller, RNLC ) 和无线网络层用户面 ( Radio Network Link Userplane, RNLU ), RNC向终 端提供一些服务流程时, 需要将提供该服务流程的多个信令按照一定的顺 序发送给终端。 如果因为网络问题, 发生丟包或重传时, 终端接收到的信 令顺序错乱, 将无法执行该流程。 例如,
在终端注册流程中, RNLU先发送下行直传信令, 然后发送无线资源 控制连接释放信令。 但是由于丟包或重传等问题, 终端接收到无线资源控 制连接释放信令之前未接收到 RNLU发送的下行直传信令, 从而导致该服 务流程无法在终端侧正常完成。
在终端分组域和电路域联合注册流程中, RNLU先发送下行直传信令, 然后发送信令链接释放信令。 但是由于丟包或重传等问题, 终端接收到信 令链接释放信令之前未收到 RNLU发送的下行直传信令, 从而导致该服务 流程无法在终端侧正常完成。
在安全模式流程中, RNLU先发送下行直传信令, 然后发送安全模式 命令信令。 但是由于丟包或重传等问题, 终端接收到安全模式命令信令之 前未收到 RNLU发送的下行直传信令, 从而导致该服务流程无法在终端侧 正常完成。
因此在现有技术中, RNLU在发送信令时按照各个信令的优先级进行 发送, 实现不同信令按照优先级顺序进行传输, 但是由于 RNLU与终端间 进行信令传输时, 可能存在丟包或重传等问题, 导致终端接收到的信令的 顺序, 与 RNC发送的信令的顺序不一致, 从而使服务流程无法在终端侧正 常完成。 发明内容
有鉴于此, 本发明实施例提供一种下行信令的传输方法、 系统及装置, 用以解决现有技术中针对需要顺序传输的信令, RNC发送该些信令的顺序 与终端接收该些信令的顺序不一致, 从而使服务流程无法在终端侧正常完 成的问题。

针对需要顺序传输的信令, 为了保证 RNC发送信令的顺序与终端接收 信令的顺序一致, 本发明实施例提供一种下行信令的传输方法, 该方法中 针对当前包含顺序传输指示信息的信令, 判断前一个非重发信令是否被终 端成功接收, 只有前一个非重发信令被所述终端成功接收时, RNC才发送 该信令。 由于本发明实施例中, 将需要顺序传输的信令中包含顺序传输指 示信息, 因此当 RNC识别到该顺序传输指示信息后, 需要判断前一个非重 发信令是否成功被终端成功接收, 从而针对需要顺序传输的信令, 保证终 端接收到的信令的顺序与 RNC发送信令的顺序一致。
下面结合说明书附图, 对本发明实施例进行详细描述。
图 1 示出了本发明实施例提供的下行信令的传输过程, 具体包括以下 步骤:
S101 : RNC针对当前待发送的信令,判断所述待发送的信令中是否包 含顺序传输指示信息。
RNC发送的信令, 由所述 RNC中的无线网络层控制面( RNLC )生成。 并且为了保证需要顺序传输的信令能够按照先后顺序进行发送并接收, 在 本发明实施例中, RNLC 中保存每个需要顺序发送的信令的信息, 并将这 些信令的信息保存在信令信息库中。 RNLC 在要生成信令时, 将该待生成 的信令与信令信息库中保存的信令信息进行匹配, 判断该待生成的信令是 否在该信令信息库中存在, 存在时, 生成包含顺序传输指示信息的信令, 否则, 生成未包含顺序传输指示信息的信令。 当 RNLC生成信令后, 将该信令发送到 RNC 中的无线网络层用户面 ( RNLU ) , 由 RNLU将每个信令发送到终端侧。
S102:当所述待发送的信令中包含所述顺序传输指示信息时,所述 RNC 判断前一个非重发信令是否被终端成功接收, 当所述前一个非重发信令被 终端成功接收时, 进行步骤 S103 , 否则, 进行步骤 S104。
在本发明实施例中, RNC判断前一个非重发信令是否被终端成功接收 包括: 所述 RNLU根据是否接收到所述终端针对所述前一个非重发信令返 回的无线链路控制确认原语( Radio Link Control ACKnowledge , RLC ACK ), 判断所述前一个非重发信令是否被终端成功接收。
S103: 所述 RNC发送所述待发送的信令。
S104: RNC重新发送所述前一个非重发信令, 直至所述前一个非重发 信令被所述终端成功接收时, 发送所述待发送的信令。
由于 RNLC生成的信令中包含顺序传输指示信息, 或, 未包含顺序传 输指示信息。 因此 RNLU接收到每个信令时, 判断待发送的信令中是否包 含顺序传输指示信息。 当 RNLU确定当前该待发送的信令中未包含顺序传 输指示信息时, 为了提高服务流程的质量, RNLU 可以根据前一个非重发 信令是否包含顺序传输指示信息, 以及该前一个非重发信令是否被终端成 功接收, 判断是否发送该未包含顺序传输指示信息的待发送的信令。
图 2示出了本发明实施例中当该待发送的信令中未包含顺序传输指示 信息时, 下行信令的传输过程, 该过程具体包括以下步骤:
S201 : RNC判断前一个非重发信令中是否包含顺序传输指示信息, 当 前一个非重发信令中包含顺序传输指示信息时, 进行步骤 S202, 否则, 进 行步骤 S204。
S202: RNC判断该前一个非重发信令是否被终端成功接收, 若是则进 行步骤 S204 , 否则进行步骤 S203。 如果 RNC直接发送该待发送的信令, 而前一个非重发信令发生丟包或 重传等问题时, 终端接收到的该前一个非重发信令和该待发送的信令的顺 序, 与 RNC的实际发送这两个信令的顺序不符, 并且当该前一个非重发信 令为实现某一服务流程的信令时, 导致终端侧针对该服务流程的质量下降。
在本发明实施例中, 当前一个非重发信令中包含顺序传输指示信息时, 说明该信令所在的服务流程中每个信令需要按照顺序进行发送, 为了保证 该服务流程在终端侧能够准确、 高效实现。 在本发明实施例中, RNC针对 前一个非重发信令, 判断该前一个非重发信令是否被终端成功接收, 直到 终端成功接收该上一时刻的信令, RNC才发送该待发送的信令。
S203: RNC重新发送该前一个非重发信令, 直至所述前一个非重发信 令被所述终端成功接收时, 发送该未包含顺序传输指示信息的待发送信令。
当上一时刻发送的信令未被终端成功接收时, RNC重新发送该上一时 刻发送的信令, 直到该上一个时刻的信令被终端成功接收时, RNC才开始 发送该待发送的信令。
S204: RNC发送该未包含顺序传输指示信息的待发送信令。
上述方案中当待发送的信令中未包含顺序传输指示信息时, RNC通过 根据前一个非重发信令是否包含顺序传输指示信息, 以及该前一个非重发 信令是否被终端成功接收, 判断是否发送该待发送的信令, 保证了包含顺 序传输指示信息的信令被终端成功接收后, 才发送其他信令。
在本发明实施例中, 为了提高下行信令的传输效率, 当 RNC确定该待 发送的信令中未包含顺序传输指示信息时, RNC也可以直接发送该待发送 的信令。
本发明实施例提供的下行信令的传输方法, RNC通过在发送需要顺序 传输的信令时, 根据前一个非重发信令是否被终端成功接收, 进行该信令 的发送, 保证终端侧接收到包含顺序传输指示信息的信令的顺序, 与 RNC 发送的顺序一致, 从而可以保证服务流程在终端侧的准确执行, 提高终端 提供服务的质量。
下面以一个具体的实施例来说明上述实现过程。
针对终端注册流程的下行信令的传输过程, 在该终端注册流程中包括 下行直传信令和无线资源控制连接释放信令, 其中, 终端必须在接收到该 下行直传信令之后, 才能接收该无线资源控制连接释放信令, 从而保证终 端注册流程在终端侧的正常实现。
并且在本发明实施例中, RNC中的 RNLC依次生成下行直传信令及无 线资源控制连接释放信令, 并按照信令生成的顺序, 依次将生成的每个信 令发送到 RNLIL 并且在 RNLC生成每个信令时, 根据自身保存的信令信 息库, 将待生成的信令与信令信息库中的信令信息进行匹配, 从而确定该 待生成的信令中是否包含顺序传输指示信息。
图 3 示出了本发明实施例提供的针对终端注册流程的下行信令的传输 过程, 该过程具体包括以下步骤:
S301 : RNLU接收 RNLC发送的下行直传信令。
在该终端注册流程中, 无线资源控制连接释放信令必须在该下行直传 信令之后被终端成功接收, 由于该下行直传信令为该终端注册流程中的第 一个信令, 因此在本发明实施例中, 针对该下行直传信令可以不要求顺序 传输,即 RNC中的 RNLC可以不将该下行直传信令保存在自身的信令信息 库中。
RNLC 生成该下行直传信令时, 将该信令与信令信息库中保存的信令 信息进行匹配, 确定该下行直传信令在该信令信息库中不存在, 因此生成 的该下行直传信令未包含顺序传输指示信息。
S302: RNLU针对当前该待发送的下行直传信令, 确认该下行直传信 令中未包含顺序传输指示信息, 判断前一个非重发信令是否包含顺序传输 指示信息, 若是, 则进行步骤 S304, 否则进行步骤 S303。
S303: RNLU向终端发送该下行直传信令。
S304: RNLU 判断前一个非重发信令是否被终端成功接收, 若是, 则 进行步骤 S303 , 否则进行步骤 S305。
当该前一个非重发信令中包含顺序传输指示信息时, 说明 RNC在上一 时刻为终端提供了服务流程, 为了提高 RNC在上一时刻提供的服务流程的 质量, RNC中的 RNLU根据该前一个发送的包含顺序传输指示信息的信令 是否被终端成功接收, 判断是否发送该待发送的信令。
S305: RNLU 重新发送前一个非重发信令, 直至所述前一个非重发信 令被所述终端成功接收时, 发送该下行直传信令。
当前一个非重发信令未被终端成功接收时, RNLU 重新发送该前一个 非重发信令, 直到终端成功接收时, RNLU才开始发送该下行直传信令。
S306: RNLU针对当前待发送的无线资源控制连接释放信令, 确认该 无线资源控制连接释放信令中包含顺序传输指示信息, 并判断发送给终端 的该下行直传信令是否被终端成功接收, 若是, 则进行步骤 S307, 否则进 行步骤 S308。
在该终端注册流程中, 由于该无线资源控制连接释放信令必须在该下 行直传信令之后被终端成功接收, 因此在本发明实施例中, 针对该无线资 源控制连接释放信令要求顺序传输,即 RNC中的 RNLC将该无线资源控制 连接释放信令保存在自身的信令信息库中。
RNLC 生成该无线资源控制连接释放信令时, 将该信令与信令信息库 中保存的信令信息进行匹配, 确定该无线资源控制连接释放信令在该信令 信息库中存在, 因此生成的该无线资源控制连接释放信令包含顺序传输指 示信息。
当终端成功接收 RNLU发送的该下行直传信令后, 针对该下行直传信 令生成 RLC ACK, 并将该 RLC ACK返回 RNLU。
S307: RNLU向终端发送该无线资源控制连接释放信令。
S308: RNLU 重新发送该下行直传信令, 直至该下行直传信令被所述 终端成功接收时, 发送该无线资源控制连接释放信令。
当 RNLU向终端发送的下行直传信令未被终端成功接收时, RNLU重 新发送该下行直传信令, 直到终端成功接收该下行直传信令时, RNLU 才 开始发送该无线资源控制连接释放信令。
在该过程中, RNC在发送无线资源控制连接释放信令时, 根据是否接 收到终端针对该下行直传信令返回的 RLC ACK, 判断该下行直传信令是否 被终端成功接收, 进行该无线资源控制连接释放信令的发送, 保证终端侧 接收到该下行直传信令和该无线资源控制连接释放信令的顺序, 与 RNC发 送这两个信令的顺序一致, 从而可以保证该终端注册流程在终端侧的准确 执行, 提高终端提供服务的质量。
并且在该过程中, 该下行直传信令中未包含顺序传输指示信息, RNC 根据上一时刻发送的信令是否包含顺序传输指示信息, 以及该前一个非重 发信令是否被终端成功接收, 判断是否发送该待发送的信令, 保证了当前 一个包含顺序传输指示信息的非重发信令被终端成功接收后, 才发送该下 行直传信令, 从而保证了该前一个发送的包含顺序传输指示信息的信令所 在的服务流程能够在终端侧准确、 高效的实现。
在该过程中, 为了提高下行信令的传输效率, RNLU 在确定该下行直 传信令中未包含顺序传输指示信息时, 也可以直接发送该下行直传信令。 釆用该方法 RNLU可以直接将该下行直传信令发送到终端侧, 无论 RNLU 在发送该下行直传信令之前发送的信令中是否包含顺序传输指示信息, 即 无论在发送下行直传信令的当前时刻的前一个非重发信令中是否包含顺序 传输指示信息, 从而实现信令的传输效率的提高。 针对终端分组域和电路域联合注册流程的下行信令的传输过程 , 在该 终端分组域和电路域联合注册流程中包括下行直传信令和信令链接释放信 令, 其中, 终端必须在接收到该下行直传信令之后, 才能接收该信令链接 释放信令, 从而保证终端分组域和电路域联合注册流程在终端侧的正常实 现。
并且在本发明实施例中, RNC中的 RNLC依次生成下行直传信令及信 令链接释放信令, 并按照信令生成的顺序, 依次将生成的每个信令发送到 RNLU。 并且在 RNLC生成每个信令时,根据自身保存的信令信息库, 将待 生成的信令与信令信息库中的信令信息进行匹配, 从而确定该待生成的信 令中是否包含顺序传输指示信息。
图 4示出了本发明实施例提供的针对终端分组域和电路域联合注册流 程的下行信令的传输过程, 该过程具体包括以下步骤:
S401 : RNLU针对当前待发送的下行直传信令, 确认该下行直传信令 中未包含顺序传输指示信息。
在该终端分组域和电路域联合注册流程中, 信令链接释放信令必须在 该下行直传信令之后被终端成功接收, 由于该下行直传信令为该终端分组 域和电路域联合注册流程中的第一个信令, 因此在本发明实施例中, 针对 该下行直传信令可以不要求顺序传输,即 RNC中的 RNLC可以不将该下行 直传信令保存在自身的信令信息库中。
RNLC 生成该下行直传信令时, 将该信令与信令信息库中保存的信令 信息进行匹配, 确定该下行直传信令在该信令信息库中不存在, 因此生成 的该下行直传信令未包含顺序传输指示信息。
S402: RNLU将该下行直传信令直接发送到终端。
在该过程中, 为了提高下行信令的传输效率, RNLU 在确定该下行直 传信令中未包含顺序传输指示信息时, 直接发送该下行直传信令。 釆用该 方法 RNLU可以直接将该下行直传信令发送到终端侧, 无论 RNLU在发送 该下行直传信令之前发送的信令中是否包含顺序传输指示信息, 而将该下 行直传信令直接发送到终端侧, 即无论在发送下行直传信令的当前时刻的 前一个非重发信令中是否包含顺序传输指示信息, 都直接发送该下行直传 信令, 从而实现信令的传输效率的提高。
S403: RNLU针对当前待发送的信令链接释放信令, 确认该信令链接 释放信令中包含顺序传输指示信息, 并判断发送给终端的该下行直传信令 是否被终端成功接收, 若是, 则进行步骤 S404, 否则进行步骤 S405。
在该终端分组域和电路域联合注册流程中, 由于该信令链接释放信令 必须在该下行直传信令之后被终端成功接收, 因此在本发明实施例中, 针 对该信令链接释放信令要求顺序传输,即 RNC中的 RNLC将该信令链接释 放信令保存在自身的信令信息库中。
RNLC 生成该信令链接释放信令时, 将该信令与信令信息库中保存的 信令信息进行匹配, 确定该信令链接释放信令在该信令信息库中存在, 因 此生成的该信令链接释放信令包含顺序传输指示信息。
当终端成功接收 RNLU发送的该下行直传信令后, 根据该下行直传信 令中包含的数据信息生成 RLC ACK, 并将该 RLC ACK返回 RNLIL
S404: RNLU向终端发送该信令链接释放信令。
S405: RNLU 重新发送该下行直传信令, 直至该下行直传信令被所述 终端成功接收时, 发送该信令链接释放信令。
当 RNLU向终端发送的下行直传信令未被终端成功接收时, RNLU重 新发送该下行直传信令, 直到终端成功接收该下行直传信令时, RNLU 才 开始发送该信令链接释放信令。
在该过程中, RNC通过在发送信令链接释放信令时, 根据是否接收到 终端针对该下行直传信令返回的 RLC ACK, 判断该下行直传信令是否被终 端成功接收, 进行该信令链接释放信令的发送, 保证终端侧接收到该下行 直传信令和该信令链接释放信令的顺序, 与 RNC发送这两个信令的顺序一 致, 从而可以保证该终端分组域和电路域联合注册流程在终端侧的准确执 行, 提高终端提供服务的质量。
并且在该过程中, 该下行直传信令中未包含顺序传输指示信息, 为了 提高下行信令的传输效率, RNLU 在确定该下行直传信令中未包含顺序传 输指示信息时, 直接发送该下行直传信令。 釆用该方法 RNLU可以直接将 该下行直传信令发送到终端侧, 无论 RNLU在发送该下行直传信令之前发 送的信令中是否包含顺序传输指示信息, 即无论在发送下行直传信令的当 前时刻的前一个发送的信令中是否包含顺序传输指示信息, 从而实现信令 的传输效率的提高。
在该过程中, 该下行直传信令中未包含顺序传输指示信息, RNC也可 以通过根据前一个非重发信令是否包含顺序传输指示信息, 以及该前一个 非重发信令是否被终端成功接收, 判断是否发送该待发送的信令。 该方法 可以保证当前一个非重发信令包含顺序传输指示信息时, 该前一个非重发 信令被终端成功接收后, 才发送该下行直传信令, 从而保证了该前一个发 送的包含顺序传输指示信息的信令所在的服务流程能够在终端侧准确、 高 效的实现。
针对安全模式流程中的下行信令的传输过程, 在该安全模式流程中包 括下行直传信令和安全模式命令信令, 其中, 终端必须在接收到该下行直 传信令之后, 才能接收该安全模式命令信令, 从而保证安全模式流程在终 端侧的正常实现。
并且在本发明实施例中, RNC中的 RNLC依次生成下行直传信令及安 全模式命令信令, 并按照信令生成的顺序, 依次将生成的每个信令发送到 RNLU。 并且在 RNLC生成每个信令时,根据自身保存的信令信息库, 将待 生成的信令与信令信息库中的信令信息进行匹配, 从而确定该待生成的信 令中是否包含顺序传输指示信息。
该针对安全模式流程的下行信令的传输过程, 与本发明实施例提供的 针对终端注册流程的下行信令的传输过程基本相同, 釆用该方法进行安全 模式流程的下行信令的传输时, 该下行直传信令中未包含顺序传输指示信 息, RNC通过根据前一个非重发信令是否包含顺序传输指示信息, 以及该 前一个非重发信令是否被终端成功接收, 判断是否发送该待发送的信令, 保证了当前一个非重发信令包含顺序传输指示信息时, 该前一个非重发信 令被终端成功接收后, 才发送该下行直传信令, 从而保证了该前一个发送 的包含顺序传输指示信息的信令所在的服务流程能够在终端侧准确、 高效 的实现。
另外, 该针对安全模式流程的下行信令的传输过程, 还可以与本发明 实施例提供的针对终端分组域和电路域联合注册流程的下行信令的传输过 程基本相同, 釆用该方法进行安全模式流程的下行信令的传输时, 为了提 高下行信令的传输效率, RNLU在确定该下行直传信令中未包含顺序传输 指示信息时, 直接发送该下行直传信令。 釆用该方法 RNLU可以直接将该 下行直传信令发送到终端侧, 无论 RNLU在发送该下行直传信令之前发送 的信令中是否包含顺序传输指示信息, 即无论在发送下行直传信令的当前 时刻的前一个非重发信令中是否包含顺序传输指示信息, 从而实现信令的 传输效率的提高。
在该针对安全模式流程的下行信令的传输过程中, RNC在发送安全模 式命令信令时, 由于该安全模式命令信令中包含顺序传输指示信息, 并且 在当前发送安全模式命令信令之前发送的为该安全模式流程中的下行直传 信令, RNC根据该安全模式流程中的下行直传信令是否被终端成功接收, 判断是否发送该安全模式流程中的安全模式命令信令。 RNC根据是否接收到终端针对该下行直传信令返回的 RLC ACK,判断 该下行直传信令是否被终端成功接收。 当 RNC接收到终端针对该下行直传 信令返回的 RLC ACK时, 确定该下行直传信令被该终端成功接收, RNC 进行该安全模式命令信令的发送。 上述实现方式可以保证终端侧接收到该 下行直传信令和该安全模式命令信令的顺序, 与 RNC发送这两个信令的顺 序一致, 从而可以保证该安全模式流程在终端侧的准确执行, 提高终端提 供服务的质量。
