1 02、 对所述中断检测指令指示的目标 MBMS 会话进行流量中断 检测;
1 0 3、 当检测到所述目标 MBM S 会话流量中断时, 译放所述目标 MBMS会话占用资源。
本发明实施例提供的一种会话处理方法, 通过获取中断检测指 令, 对所述中断检测指令指示的目标 MBMS会话进行流量中断检测, 当检测到所述目标 MBMS会话流量中断时, 释放所述目标 MBMS会话 占用资源。 本发明实施例解决了现有技术中当某个 MBM S会话连续一 段时间都没有正常工作时, 所述 MBMS会话将继续占用网元的资源的 问题, 实现了因会话流量中断产生残留会话时, 能够主动释放残留 会话占用的资源, 节约网络资源。
本发明实施例提供的一种会话处理方法, 一种实现方式以网元 MBMS GW处理 MBMS残留会话为例进行说明, 其中, 网络维护人员预 先在所述 MBMS GW上为所有已建立的 MBMS会话配置相同的第一门限 值, 并通过对所述 MBMS GW 下发中断检测指令, 以便所述 MBMS GW 对所有 MBMS会话产生的流量进行实时检测, 并对 MBMS 残留会话进 行相关处理, 如图 2所示, 具体步骤如下:
2 01、 所述 MBMS GW获取输入的中断检测指令, 所述中断检测指 令包含 MBMS GW管理的目标 MBMS会话对应相同的第一门限值。
其中, 所述获取输入的中断检测指令具体为获取网络维护人员 输入的中断检测指令。 本发明实施例是以网元 MBMS GW 为粒度进行 MBMS 残留会话的处理, 所述 MBMS GW管理的所有目标 MBMS 会话都 配置相同的第一门限值。
所述 MBMS GW在获取到中断检测指令后, 启动所述中断检测指 令指示的目标 MBMS会话对应的定时器, 并将所述目标 MBMS会话对 应的预设计数器清零。 其中, 一个会话对应一个定时器和预设计数 器, 具体如步骤 2 02。
2 02、 所述 MBMS GW启动所述中断检测指令指示的所述 MBMS GW 管理的目标 MBMS会话对应的定时器, 并将所述所有目标 MBMS会话 对应的预设计数器清零。
其中, 所有目标 MBMS 会话都有属于各自的定时器和预设计数 器。 所述所有目标 MBMS会话对应的定时器的规定时间都相同, 例如 设为 1 分钟。 因为本实施例是以 MBMS GW为粒度进行第一门限值的 配置, 所有目标 MBMS会话配置相同的第一门限值, 所以下面以一个 目标 MBMS会话为例进行说明。
其中为每个会话设置一个定时器的作用, 是为了避免将出现较 短时间间隔中断的正常会话误判为残留会话。 例如, 如果不设置定 时器, 则每次检测的时间间隔可能为 1 秒, 甚至更短, 此时, 一些 正常会话也可能出现较短时间间隔的中断, 而这类中断不属于造成 残留会话的中断, 也不需要释放此类中断对应会话占用的资源。 可 见, 通过设置定时器 (例如, 可以为该定时器设定 1 分钟的定时时 间, 当然, 根据实际应用需求的不同, 也可以设置成不同的定时时 间 ), 可以避免将出现此类较短时间间隔中断的正常会话误判为残留 会话。
2 03、 当所述目标 MBMS 会话对应的定时器到达规定时间时, 所 述 MBMS GW获取所述目标 MBMS会话产生的流量。
获取的所述目标 MBMS会话产生的流量, 是在所述定时器到达所 述规定时间点时的总流量。 例如, 当所述目标 MBMS会话对应的定时 器的规定时间为 1 分钟时, 1 分钟过后, 所述 MBMS GW获取所述目 标 MBMS会话在 1分钟过后的这个时间点, 产生的总流量值。
2 04、 当本次获取的所述目标 MBMS 会话产生的流量大于前次获 取的所述目标 MBMS会话产生的流量时, 所述 MBMS GW将所述预设计 数器的值清零;
当本次获取的所述目标 MBMS 会话产生的流量大于前次获取的 所述目标 MBMS会话产生的流量时, 说明在本次启动所述定时器的这 段规定时间内, 所述目标 MBMS会话有数据通过, 并没有中断, 则将 所述 MBMS GW将所述预设计数器的值清零。
2 05、 当本次获取的所述目标 MBMS 会话产生的流量等于前次获 取的所述目标 MBMS会话产生的流量时, 所述 MBMS GW将所述预设计 数器的值增加一, 或者将所述预设计数器的值增加一个单位时长, 所述一个单位时长的取值为所述定时器从零到达所述规定时间的时 长。
当本次获取的所述目标 MBMS 会话产生的流量等于前次获取的 所述目标 MBMS会话产生的流量时, 说明在本次启动所述定时器的这 段规定时间内, 所述目标 MBMS会话没有数据通过, 暂时产生了数据 中断, 则所述 MBMS GW将所述预设计数器的值增加一或者增加一个 单位时长。
可选的, 将所述预设计数器的值增加一, 此时所述预设计数器 的值用于表示会话中断次数;
可选的, 将所述预设计数器的值增加一个单位时长, 此时所述 预设计数器的值用于表示会话中断时长。 2 06、 当所述预设计数器的值小于第一门限值时, 所述 MBMS GW 重启所述定时器, 跳转执行步骤 2 0 3。
可选的, 当上述步骤 2 05 中将所述预设计数器的值增加一时, 所述第一门限值可以设置为表示中断次数的门限值;
可选的, 当上述步骤 2 05 中将所述预设计数器的值增加一个单 位时长时, 所述第一门限值可以设置为表示中断时长的门限值。
在所述预设计数器的值经过增加一或者增加一个单位时长, 或 者清零后, 仍然小于第一门限值时, 则说明所述目标 MBMS会话的中 断次数或者中断时长小于所述第一门限值, 重启所述定时器, 继续 执行步骤 2 03 , 进行所述目标 MBMS会话的流量检测, 以便当检测到 所述目标 MBMS会话流量中断时, 释放所述目标 MBMS会话占用资源, 具体如步骤 2 07。
2 07、 当所述预设计数器的值等于第一门限值时, 所述 MBMS GW 译放所述目标 MBMS会话占用资源。
可选的, 所述第一门限值可以设置为表示中断次数的门限值, 当所述预设计数器的值等于第一门限值时, 说明所述目标 MBMS会话 的中断次数达到了规定的第一门限值, 已经形成 MBMS残留会话, 为 了不浪费网络中的资源, 所述 MBMS GW释放所述目标 MBMS会话占用 资源。
可选的, 所述第一门限值还可以设置为表示中断时长的门限值, 利用所述预设计数器的中断时长与所述第一门限值进行比较, 例如, 当所述定时器的规定时间为 1分钟, 所述第一门限时长为 1 44 0分钟 ( 24 小时)时, 当所述预设计数器的值为 1 44 0分钟时, 则所述 MBMS GW释放所述目标 MBMS会话占用资源。
另外, 当所述预设计数器的值等于第一门限值, 所述 MBMS GW 译放所述目标 MBMS会话占用资源的同时, 要通知上下行网元译放所 述目标 MBMS会话占用资源, 如图 2所示, 在执行步骤 2 07之后, 执 行步骤 2 08。
2 08、 所述 MBMS GW通知上下行网元释放所述目标 MBMS会话占 用资源。
具体为所述 MBMS GW通过 Session Termination Request 会话 终止申请消息通知上行网元 BM-SC 译放所述目标 MBMS 会话占用资 源, 通过 MBMS Session S t op 多媒体广播多播服务会话停止消息通 知下行网元 MME/SGSN释放所述目标 MBMS会话占用资源。
可选的, 可对被释放占用资源的目标 MBMS会话进行记录, 或者 生成日志, 此处不做限定。
另外, 可选的, 如果网络维护人员输入的中断检测指令中还包 含第二门限值时, 且所述第二门限值小于所述第一门限值, 则如图 3所示, 在执行步骤 206之前, 执行步骤 209。
209、 当所述预设计数器的值等于所述第二门限值时, 所述 MBMS GW上 ^艮所述目标 MBMS会话的中断告警。
对于长时间没有数据通过的目标 MBMS会话, 所述 MBMS GW将上 报所述目标 MBMS会话的中断告警, 便于网络维护人员及时地获知所 述中断的目标 MBMS会话, 并根据需要进行相关处理。
可选的, 所述第二门限值还可以设置为表示中断时长的门限值, 利用所述预设计数器的中断时长与所述第二门限值进行比较。
可选的, 当网络维护人员输入停止中断检测指令时, 所述 MBMS GW将会停止对所有目标 MBMS会话的中断检测。
本发明实施例的另一种实现方式, 以网元 MBMS GW处理 MBMS残 留会话为例进行说明,其中,通过 BM-SC向所述 MBMS GW下发的 MBMS 会话对应信令, 为目标 MBMS会话配置中断检测指令, 以及各自的第 一门限值, 如图 4所示, 具体步骤如下:
400、 上行网元 BM-SC 向 MBMS GW 发送目标 MBMS 会话对应 diameter 信令, 所述 diameter 信令中携带中断检测指令, 所述中 断检测指令包含所述目标 MBMS会话对应的第一门限值;
401、 所述 MBMS GW获取所述 BM-SC发送的目标 MBMS会话对应 所述 diameter信令, 所述 d i ame t er信令中携带中断检测指令, 所 述中断检测指令包含所述目标 MBMS会话对应的第一门限值; 402、 所述 MBMS GW启动所述中断检测指令指示的所述目标 MBMS 会话对应的定时器, 并将所述目标 MBMS 会话对应的预设计数器清 令。
在本实现方式中, 所述 MBMS GW对获取到具有中断检测指令的 MBMS会话进行中断检测, 与上一实现方式不同, 本方式中只对具有 中断检测指令的 MBMS会话进行中断检测, 而上一实现方式则是对所 述 MBMS GW 管理的所有 MBMS 会话进行中断检测, 并且在本方式中 MBMS 会话都有对应的第一门限值, 具有中断检测指令的 MBMS 会话 的第一门限值可能不同, 而上一实现方式中所述 MBMS会话的第一门 限值都相同, 因此, 本实现方式是以 MBMS会话为粒度进行中断检测 的, 更适用于不同的 MBMS会话。 并且所有目标 MBMS会话都有属于 各自的定时器和预设计数器, 所述所有目标 MBMS会话对应的定时器 的规定时间都相同, 下面就以一个 MBMS会话为例进行说明。
其中为每个会话设置一个定时器的作用, 是为了避免将出现较 短时间间隔中断的正常会话误判为残留会话。 例如, 如果不设置定 时器, 则每次检测的时间间隔可能为 1 秒, 甚至更短, 此时, 一些 正常会话也可能出现较短时间间隔的中断, 而这类中断不属于造成 残留会话的中断, 也不需要释放此类中断对应会话占用的资源。 可 见, 通过设置定时器 (例如, 可以为该定时器设定 1 分钟的定时时 间, 当然, 根据实际应用需求的不同, 也可以设置成不同的定时时 间 ), 可以避免将出现此类较短时间间隔中断的正常会话误判为残留 会话。
步骤 401 中的 diameter信令是所述 MBMS GW与所述 BM-SC之间 基于 Diameter链路发送的信令, 对所述 diameter信令进行私有扩 展, 并将所述中断检测指令携带在所述 diameter信令中, 所述中断 检测指令包含所述目标 MBMS会话对应的第一门限值。
403、 当所述目标 MBMS 会话对应的定时器到达规定时间时, 所 述 MBMS GW获取所述目标 MBMS会话产生的流量。
获取的所述目标 MBMS会话产生的流量, 是在所述定时器到达所 述规定时间点时的总流量。 例如, 当所述目标 MBMS会话对应的定时 器的规定时间为 1 分钟时, 1 分钟过后, 所述 MBMS GW获取所述目 标 MBMS会话在 1分钟过后的这个时间点, 产生的总流量值。
4 04、 当本次获取的所述目标 MBMS 会话产生的流量大于前次获 取的所述目标 MBMS会话产生的流量时, 所述 MBMS GW将所述预设计 数器的值清零;
当本次获取的所述目标 MBMS 会话产生的流量大于前次获取的 所述目标 MBMS会话产生的流量时, 说明在本次启动所述定时器的这 段规定时间内, 所述目标 MBMS会话有数据通过, 并没有中断, 则将 所述 MBMS GW将所述预设计数器的值清零。
4 05、 当本次获取的所述目标 MBMS 会话产生的流量等于前次获 取的所述目标 MBMS会话产生的流量时, 所述 MBMS GW将所述预设计 数器的值增加一, 或者将所述预设计数器的值增加一个单位时长, 所述一个单位时长的取值为所述定时器从零到达规定时间的时长。
当本次获取的所述目标 MBMS 会话产生的流量等于前次获取的 所述目标 MBMS会话产生的流量时, 说明在本次启动所述定时器的这 段规定时间内, 所述目标 MBMS会话没有数据通过, 暂时产生了数据 中断, 则所述 MBMS GW将所述预设计数器的值增加一或者增加一个 单位时长。
可选的, 将所述预设计数器的值增加一, 此时所述预设计数器 的值用于表示会话中断次数;
可选的, 将所述预设计数器的值增加一个单位时长, 此时所述 预设计数器的值用于表示会话中断时长。
4 06、 当所述预设计数器的值小于第一门限值时, 所述 MBMS GW 重启所述定时器, 跳转执行步骤 4 0 3。
可选的, 当上述步骤 4 05 中将所述预设计数器的值增加一时, 所述第一门限值可以设置为表示中断次数的门限值;
可选的, 当上述步骤 4 05 中将所述预设计数器的值增加一个单 位时长时, 所述第一门限值可以设置为表示中断时长的门限值。 在所述预设计数器的值经过增加一或者增加一个单位时长, 或 者清零后, 仍然小于第一门限值时, 则说明所述目标 MBMS会话的中 断次数或者中断时长小于所述第一门限值, 重启所述定时器, 继续 执行步骤 403, 进行所述目标 MBMS会话的流量检测, 以便当检测到 所述目标 MBMS会话流量中断时, 释放所述目标 MBMS会话占用资源, 具体如步骤 407。
407、 当所述预设计数器的值等于第一门限值时, 所述 MBMS GW 译放所述目标 MBMS会话占用资源。
可选的, 所述第一门限值可以设置为表示中断次数的门限值, 当所述预设计数器的值等于第一门限值时, 说明所述目标 MBMS会话 的中断次数达到了规定的第一门限值, 已经形成 MBMS残留会话, 为 了不浪费网络中的资源, 所述 MBMS GW释放所述目标 MBMS会话占用 资源。
可选的, 所述第一门限值可以设置为表示中断时长的门限值, 利用所述预设计数器的中断时长与所述第一门限值进行比较, 例如, 当所述定时器的规定时间为 1分钟, 所述第一门限时长为 1440分钟 ( 24 小时)时, 当所述预设计数器的值为 1440分钟时, 则所述 MBMS GW释放所述目标 MBMS会话占用资源。
另外, 当所述预设计数器的值等于第一门限值, 所述 MBMS GW 译放所述目标 MBMS会话占用资源的同时, 要通知上下行网元译放所 述目标 MBMS会话占用资源, 如图 4所示, 在执行步骤 407之后, 执 行步骤 408。
408、 所述 MBMS GW通知上下行网元释放所述目标 MBMS会话占 用资源。
具体为所述 MBMS GW通过 Session Termination Request 会话 终止申请消息通知上行网元 BM-SC 译放所述目标 MBMS 会话占用资 源, 通过 MBMS Session S t op 多媒体广播多播服务会话停止消息通 知下行网元 MME/SGSN释放所述目标 MBMS会话占用资源。
可选的, 可对被释放占用资源的目标 MBMS会话进行记录, 或者 生成日志, 此处不做限定。
另夕卜, 可选的, 如果所述上行网元 BM-S C发送的所述目标 MBMS 会话对应信令中, 还包含第二门限值时, 且所述第二门限值小于所 述第一门限值, 则在执行步骤 4 06之前,如图 5所示,执行步骤 4 09。
4 09、 当所述预设计数器的值等于所述第二门限值时, 所述 MBMS GW上 ^艮所述目标 MBMS会话的中断告警。
对于长时间没有数据通过的目标 MBMS会话, 所述 MBMS GW将上 报所述目标 MBMS会话的中断告警, 便于网络维护人员及时地获知所 述中断的目标 MBMS会话, 并根据需要进行相关处理。
可选的, 所述第二门限值还可以设置为表示中断时长的门限值, 利用所述预设计数器的中断时长与所述第二门限值进行比较。
可选的, 当网络维护人员输入停止中断检测指令时, 所述 MBMS GW将会停止对所有目标 MBMS会话的中断检测。
本发明实施例也可应用于当 BM- S C 因为异常导致复位, 丟失已 经建立的 MBMS 会话时, 若要释放 MBMS 会话占用资源, 所述 BM-S C 将无法向 MBMS GW发出请求时, 则可以应用上述实施例由所述 MBMS GW进行 MBMS会话的检测, 并且当 MBMS会话连续一段时间没有正常 工作时, 释放所述 MBMS 会话占用资源, 并通知下行网元 MME / S G SN 译放所述 MBMS会话占用资源。
