本发明目的的实现、 功能特点及优点将结合实施例， 参照附图做进一 步说明。 具体实施方式
应当理解， 此处所描述的具体实施例仅仅用以解释本发明， 并不用于 限定本发明。
参照图 1 , 本发明实施例定位移动终端死机问题的方法， 包括： 步驟 10、 存储信令数据到预设的存储空间；
本实施例中， 可在手机等移动终端中开辟一段能保存可供分析使用的 信令数据的存储空间如 flash空间， 也可以外置一存储空间， 用于保存信令 数据， 该存储空间必须是在移动终端出现死机后仍然可以被定位装置读取 的存储空间。 当移动终端处于开机状态时， 移动终端与其它终端或设备之 间会建立连接， 并有信令数据的交互， 当移动终端接收到信令数据时， 将 该信令数据存放于已设置的存储空间。
以 2M的 Flash为例写存储空间的具体实施方式如下： 将有限的 2M Flash空间等分为两块， 每块大小为 1M。 设定往哪个块 写的全局变量 MsgTraceFlashAreaFlag , 初始状态下 MsgTraceFlashAreaFlag 等于 0 , 写块 1 时 MsgTraceFlashAreaFlag 等于 1 , 写块 2 时 MsgTraceFlashAreaFlag 等于 2。 设定表示剩余 flash 空间大小的全局变量 Remain , 如果所要存储的信令数据大于 1M , 将做丟弃处理， 读取 MsgTraceFlashAreaFlag 的值， 根据所读到的值来判断往哪一块空间写。 如 果 MsgTraceFlashAreaFlag值为 0, 表示是移动终端开机的初始状态， 将信 令数据往块 1上写。 如果 MsgTraceFlashAreaFlag值为 1 , 表示是将信令数 据往块 1上写。 如果 MsgTraceFlashAreaFlag值为 2, 表示是将信令数据往 块 2上写。 读取 Remain的值， 根据所读到的值与信令数据的长度对比以判 断剩余的 Flash空间是否足够存下当前的信令数据，如果信令数据长度小于 Remain的值， 直接将信令数据写入当前块， 如果信令数据长度等于 Remain 的值， 直接将信令数据写入当前块， 然后将 MsgTraceFlashAreaFlag置为另 一存储块的标志， 将地址指针置为另一存储块的起始地址。 如果信令数据 长度大于 Remain 的值， 将信令数据写入另一存储块， 然后将 MsgTraceFlashAreaFlag置为另一存储块的标志。 至此， 信令数据就成功存 到 Flash空间。
步驟 11、 移动终端死机或关机后， 预设的定位装置读取所述存储空间 内的信令数据；
如移动终端出现死机或正常关机后， PC等定位装置通过在存放信令数 据的存储空间中取出信令数据。
步驟 12、 所述定位装置分析所述信令数据以定位死机问题。
定位装置对取出的信令数据进行分析以定位手机死机问题。 PC对信令 数据进行解析得到的信息如下所示， 如此就可以恢复移动终端死机前的信 令现场。
Figure imgf000007_0001
本实施例的定位移动终端死机问题的方法不仅适用于移动终端， 实际 上， 只要是具有读写存储空间功能的设备的死机问题定位都适用于本实施 例的方法。
参照图 2, 在一实施例中， 步驟 10可进一步包括：
步驟 101、 提取移动终端内预设类型的信令数据；
步驟 102、 将所述信令数据写入所述存储空间。
上述预设类型的信令数据包括移动终端内指针信令所指向的数据。 移动终端在收发信令数据时， 首先决定存储哪些类型的信令数据， 由 于存储空间的容量有限， 通常不建议存放所有的信令数据， 而是预设某一 种或多种对复现信令现场有用的信令数据进行存储。 特别是对于信令数据 中的指针内容， 需要将所述指针内容所指向的数据存放也一起保存于存储 空间中。
在上述实施例中， 步驟 12进一步包括： 对所述信令数据进行解析。 由于存储空间中保存的信令数据可能包括指针内容所指向的数据存 放， 因此在读取存储空间的信令数据时， 在将存储空间的数据从二进制转 化为移动终端的信令数据的同时， 还需要将原指针内容所指向的数据也进 行还原。 参照图 3 , 提出本发明定位移动终端死机问题的方法又一实施例， 在 上述实施例中， 在步驟 10之前， 还包括：
步驟 9、 当所述存储空间容量不足时， 删除之前存储的信令数据。 由于存储空间的容量有限， 应对所述存储空间进行重复利用， 即信令 数据存满存储空间后再从头开始， 覆盖原有信令数据， 存放新的信令数据， 以便节约存储空间。
参照图 4, 本发明实施例定位移动终端 10死机问题的系统， 包括移动 终端 10和定位装置 20, 其中，
所述移动终端 10, 用于存储信令数据到预设的存储空间；
所述定位装置 20, 用于移动终端 10死机或关机后， 读取所述存储空 间内的信令数据； 以及分析所述信令数据以定位死机问题。
本实施例中，可在手机等移动终端 10中开辟一段能保存可供分析使用 的信令数据的存储空间如 flash空间， 也可以外置一存储空间， 用于保存信 令数据， 该存储空间必须是在移动终端 10出现死机后仍然可以被定位装置 20 (如安装有分析软件的 PC )读取的存储空间。 当移动终端 10处于开机 状态时， 移动终端 10与其它终端或设备之间会建立连接， 并有信令数据的 交互， 当移动终端 10接收到信令数据时， 存储模块 10将该信令数据存放 于已设置的存储空间。
以 2M的 Flash为例写存储空间的具体实施方式如下：
将有限的 2M Flash空间等分为两块， 每块大小为 1M。 设定往哪个块 写的全局变量 MsgTraceFlashAreaFlag , 初始 ^夫态下 MsgTraceFlashAreaFlag 等于 0 , 写块 1 时 MsgTraceFlashAreaFlag 等于 1 , 写块 2 时 MsgTraceFlashAreaFlag 等于 2。 设定表示剩余 flash 空间大小的全局变量 Remain , 如果所要存储的信令数据大于 1M , 将做丟弃处理， 读取 MsgTraceFlashAreaFlag 的值， 根据所读到的值来判断往那一块空间写。 如 果 MsgTraceFlashAreaFlag值为 0, 表示是移动终端 10开机的初始状态， 将 信令数据往块 1上写。 如果 MsgTraceFlashAreaFlag值为 1 , 表示是将信令 数据往块 1上写。 如果 MsgTraceFlashAreaFlag值为 2, 表示是将信令数据 往块 2上写。 读取 Remain的值， 根据所读到的值与信令数据的长度对比以 判断剩余的 Flash空间是否足够存下当前的信令数据，如果信令数据长度小 于 Remain 的值， 直接将信令数据写入当前块， 如果信令数据长度等于 Remain的值， 直接将信令数据写入当前块， 然后将 MsgTraceFlashAreaFlag 置为另一存储块的标志， 将地址指针置为另一存储块的起始地址。 如果信 令数据长度大于 Remain 的值， 将信令数据写入另一存储块， 然后将 MsgTraceFlashAreaFlag 置为另一存储块的标志。 至此， 信令数据就成功存 到 Flash空间。
如移动终端 10出现死机或正常关机后， PC等定位装置 20通过在存放 信令数据的存储空间中取出信令数据， 并对取出的信令数据进行分析以定 位手机死机问题。 PC对信令数据进行解析得到的信息如下所示， 如此就可 以恢复移动终端 10死机前的信令现场。
需要注意的是，本实施例的移动终端 10可以是其它任何具有读写存储 参照图 5 , 在一实施例中， 移动终端 10包括：
提取模块 11 , 用于提取移动终端 10内预设类型的信令数据； 写入模块 12, 用于将所述信令数据写入所述存储空间。
上述预设类型的信令数据包括移动终端 10内指针信令所指向的数据。 移动终端 10在收发信令数据时， 首先决定存储哪些类型的信令数据， 由于存储空间的容量有限， 通常不建议存放所有的信令数据， 而是由提取 模块 11 提取某一种或多种对复现信令现场有用的信令数据给写入模块 12 写入存储空间。 特别是对于信令数据中的指针内容， 需要将所述指针内容 所指向的数据也一起存放于存储空间中。
在上述实施例中， 定位装置 20用于对所述信令数据进行解析。
由于存储空间中保存的信令数据可能包括指针内容所指向的数据存 放， 因此定位装置 20在读取存储空间的信令数据时， 在将存储空间的数据 从二进制转化为移动终端 10的信令数据的同时， 还需要将原指针内容所指 向的数据也进行还原。
参照图 6,本发明另一个实施例中的定位移动终端 10死机问题的装置， 其移动终端 10除包含上述实施例中的提耳 4莫块 11和写入模块 12外， 还可 以包括： 删除模块 13 , 用于当所述存储空间容量不足时， 删除之前存储的 信令数据。
由于存储空间的容量有限， 应对所述存储空间进行重复利用， 即信令 数据存满存储空间后再从头开始， 删除模块 13覆盖原有信令数据， 以便写 入模块 12存放新的信令数据， 节约存储空间。
以上所述仅为本发明的优选实施例， 并非因此限制本发明的专利范围 , 凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换， 或直 接或间接运用在其他相关的技术领域， 均同理包括在本发明的专利保护范 围内。
