按照前述实施例中的描述, 在图 4所示的组网结构中, TDM交换机为第 一 TDM设备, 用户终端为第二 TDM设备, 网络侧网关为第一数据处理网关, 用户侧网关为第二数据处理网关。
基于图 4所描述的结构,下面分别以主叫流程和被叫流程为例对本发明数 据处理方法进行伴细描述:
一、 主叫流程:
请参阅图 5, 本发明数据处理方法另一实施例包括:
501、 用户终端摘机;
本实施例中, 用户终端作为主叫用户, 当其摘机时, 会向与其通过模拟用 户线连接的用户侧网关发送语音信号。
502、 用户侧网关向网络侧网关发送摘机信号;
当用户侧网关接收到用户终端摘机时发出的语音信号时 ,可以根据该语音 信号中的特征获知该语音信号用以表示用户终端摘机,则确定该语音信号为语 音控制信号, 具体为摘机信号。
用户侧网关获取到摘机信号之后, 需要将该摘机信号转换为控制特征信 息, 并封装入 IP报文中。
用户侧网关和网络侧网关通过 IP网络相连,可以采用传输控制协议( TCP , Transport Control Protocol )或用户数据 4艮协议( UDP, User Datagraph Protocol ), 或者其他类似网络传输协议传输数据, 本实施例中, 仅以 UDP协议为例进行 说明。
本实施例中, 使用 ΙΡ ·¾文中的 UDP payload字段作为控制字段, 在该字 段中携带控制特征信息。
用户侧网关以及网络侧网关中预先配置的 "控制特征信息与语音控制信 号" 之间的对应关系如下表所示:
表 1
Figure imgf000008_0001
上述表 1中描述的内容仅为本实施例中的具体例子,在实际应用中,具体 数值以及类型均可以进行调整, 此处不作限定。
按照上述表 1所示的内容, 用户侧网关可以获取到 "摘机"对应的控制特 征信息为 "0X1A" , 则将 "0X1A" 填入 IP报文中的 UDP payload字段, 并将 IP 文通过 IP接口, 采用 IP网络发送至网络侧网关。
本实施例中的 IP接口可以是 GE接口, 也可以是 FE接口, 或者还可以是 其他类型的 IP接口, 具体此处不作限定。

网络侧网关通过 IP接口从 IP网 ^矣收到用户侧网关发送的 IP报文之后 , 根据预先的约定, 网络侧网关读取 IP报文中预置的控制字段, 即 UDP payload 字段。
网络侧网关可以判断该 UDP payload字段中存放的数据是否为非控制数 据。 需要说明的是,本实施例中, UDP payload字段中可以存放控制特征信息, 也可以存放语音媒体数据信息,还可以存放其他类型的数据, 所以网络侧网关 获取到 UDP payload字段之后 , 则可以判断该 UDP payload字段中存放的数据 是否为非控制数据, 非控制数据是指除控制特征信息之外的其他数据,具体的 控制特征信息如前述表 1所示。
本实施例中, 网络侧网关可以通过 UDP payload字段中的内容、 字符长度 或者是通过循环冗余校验等方式以判断 UDP payload字段中存放的数据是否 为非控制数据, 可以理解的是, 网络侧网关还可以通过其他的方式判断 UDP payload字段中存放的数据是否为非控制数据, 具体此处不作限定。
网络侧网关读取出 UDP payload字段中的数值为 "0X1A" , 可以与表 1中 的控制特征信息进行匹配, 根据表 1 可以获取到对应的语音控制信号为 "摘 机" , 则网络侧网关通过 Z接口向 TDM交换机发送主叫摘机信号。
本实施例中, 网络侧网关与 TDM交换机之间可以通过模拟用户线连接。 需要说明的是,前述表 1中描述的控制特征信息仅是实际应用中的一个例 子, 由于网络传输可能会受到各种未知的干扰, 为了防止出现误检, 可以将控 制特征信息采用某种转换算法, 例如哈希算法, 转换成一组数字序列, 然后将 该数字序列填入控制字段。
此外, 出于安全性的考虑, 还可以对控制字段中的控制特征信息, 或者是 控制特征信息转换后的数字序列进行加密。
在实际应用中还可以对控制特征信息采取更多的处理方式,具体此处不作 限定。
504、 TDM交换机发送拨号音;
TDM交换机根据网络侧网关发送的信号获知主叫已摘机, 则 TDM交换 机向网络侧网关发送语音信号, 该语音信号为拨号音。
505、 网络侧网关向用户侧网关发送拨号音;
网络侧网关通过 Z接口从 TDM交换机接收到语音信号,可以根据该语音 信号中的特征获知该语音信号为语音数据信号, 具体为拨号音。
网络侧网关获取到语音信号为拨号音之后, 可以将该拨号音封装为 IP报 文, 由于该语音信号不是语音控制信号, 所以网络侧网关可以在 IP报文中的 UDP payload字段直接填写拨号音数据。
需要说明的是, 若在实际应用中, 拨号音也被设置为语音控制信号, 则具 体的处理方式按照语音控制信号的处理方式进行, 此处不作限定。
封装得到 IP报文之后 , 网络侧网关将该 IP报文通过 IP接口, 采用 IP网 络发送至用户侧网关。
506、 用户侧网关向用户终端发送拨号音;
用户侧网关通过 IP接口从 IP网 ^矣收到网络侧网关发送的 IP报文之后 , 根据预先的约定,用户侧网关读取 IP报文中预置的控制字段, 即 UDP payload 字段。
用户侧网关读取出 UDP payload字段,通过与表 1中的控制特征信息进行 比较获知该 UDP payload字段中存放的数据为非控制数据,则用户侧网关可以 进一步判断 UDP payload字段中存放的数据是否为语音数据信号,若是语音数 据信号,则用户侧网关可以将 UDP payload字段中的数据通过 Z接口发送给用 户终端, 若不是语音数据信号, 则说明该 UDP payload字段中存放的是其他类 型的数据, 则用户侧网关根据该 UDP payload字段中的数据自行进行处理, 具 体处理过程此处不作限定。 音数据信号, 则将 UDP payload字段中的数据通过 Z接口发送给用户终端。
507、 用户拨号;
用户侧网关向用户终端发送数据之后, 用户则可听到拨号音, 随后可以开 始拨号, 用户终端可以将用户拨出的号码通过语音信号发送给用户侧网关。
508、 用户侧网关收号;
用户侧网关接收到语音信号之后 ,可以获知该语音信号用以表示用户终端 拨号, 则确定该语音信号为语音控制信号, 具体为拨号信号。
本实施例中, 用户侧网关可以在本地完成收号, 并进行数图匹配后统一上 报, 也可以逐位上报, 具体此处不作限定, 仅以统一上报为例进行说明。
为了提高用户体-险,用户侧网关可以在收到用户终端发送的第一个号码之 后即停止向用户终端发送拨号音数据。
本实施例中, 用户侧网关进行数图匹配的大致过程可以为: 用户侧网关将收到的号码先存放在一个緩冲区中,并将收到的号码与数图
( digitmap ) 中的条目进行比较, 如果收到的号码与某个条目完全匹配, 则用 户侧网关可以上 4艮该号码; 若收到的号码与某个条目部分匹配, 则用户侧网关 等待用户继续输入号码, 直至收到的号码与某个条目完全匹配。
例如用户侧网关中的数图为 (1 【3, 5, 8】 xxxxxxxxx|95xxx|l 【1, 2】 x|
【2 ~ 8】 xxxxxxx ), 该数图中包含如下条目:
1 【3, 5, 8】 xxxxxxxxx: 表示第 1位为 "1", 第 2位为 "3, 5, 8" 中的 任意一个数字, 第 3位至第 11位为 "0~9" 中的任意数字;
95xxx: 表示第 1位为 "9", 第 2位为 "5", 第 3位至第 5位为 "0 ~ 9" 中的任意数字;
1 【1, 2】 X: 表示第 1位为 "Γ, 第 2位为 "1, 2" 中的任意一个数字, 第 3位为 "0~9" 中的任意一个数字;
【2 ~ 8】 xxxxxxx: 表示第 1位为 "2~8" 中的任意一个数字, 第 2位至 第 8位为 "0~9', 中的任意数字。
假设用户输入的第 1个数字为 "1", 则用户侧网关获知收号的号码与条目
"1 【3, 5, 8】 xxxxxxxxx" 以及 "1 【1, 2】 x" 部分匹配, 则将 "1" 存入緩 冲区内, 暂不上报;
用户输入的第 2个数字为 "1", 则用户侧网关获知收号的号码与条目 "1 【1, 2】 X" 部分匹配, 则将 "1" 存入緩冲区内, 暂不上报;
假设用户输入的第 3个数字为 "0", 则用户侧网关获知收号的号码与条目
"1【1, 2】x,,完全匹配, 则将 "0"存入緩冲区内, 并对緩冲区内的号码 "110" 进行上报。
需要说明的是, 上述仅以一个具体实例说明了本实施例中数图匹配的过 程, 可以理解的是, 在实际应用中, 数图的内容以及数图匹配的过程均为本领 域技术人员的公知常识, 具体此处不作限定。

请参阅图 6, 本发明数据处理方法另一实施例包括:
601、 TDM交换机发送振铃信号;
本实施例中, 用户终端作为被叫用户, 当有主叫用户呼叫该用户终端时, 主叫用户的呼叫请求会首先到达 TDM交换机, 则 TDM交换机会根据被叫号 码向与其通过模拟用户线连接的网络侧网关发送语音信号。
602、 网络侧网关向用户侧网关发送振铃信号;
当网络侧网关接收到 TDM交换机发出的语音信号时, 可以根据该语音信 号中的特征获知该语音信号用以表示 TDM交换机发送振铃信号, 则确定该语 音信号为语音控制信号, 具体为振铃信号。
网络侧网关获取到振铃信号之后 , 需要将该振铃信号转换为控制特征信 息, 并封装入 IP报文中。
网络侧网关和用户侧网关通过 IP网络相连, 可以采用 TCP协议或 UDP 协议, 或者其他类似网络传输协议传输数据, 此处不作限定, 本实施例中, 仅 以 UDP协议为例进行说明。
本实施例中, 使用 ΙΡ ·¾文中的 UDP payload字段作为控制字段, 在该字 段中携带控制特征信息。
网络侧网关以及用户侧网关中预先配置的 "控制特征信息与语音控制信 号" 之间的对应关系如前述表 1所示。
表 1中描述的内容仅为本实施例中的具体例子,在实际应用中,具体数值 以及类型均可以进行调整, 此处不作限定。
本实施例可以使用表 1 所示的内容实现网络侧网关与用户侧网关之间的 通信, 可以理解的是, 在实际应用中, 也可以采用其他的方式, 例如:
网络侧网关和用户侧网关之间传输的 IP报文可以采用某种成熟的语音控 制信令, 例如 H.248, 或媒体网关控制协议(MGCP, Media Gateway Control Protocol ), 或^舌初始化协议( SIP, Session Initiation Protocol ), 此时需要网 络侧网关以及用户侧网关具有对应信令的解析能力。
在实际应用中,网络侧网关与用户侧网关之间还可以通过更多种方式实现 通信, 具体此处不作限定, 仅以表 1所示的内容为例进行说明。

604 ~ 606、 来电显示信号发送过程;
本实施例中, 若被叫用户开通了来电显示业务, 则 TDM交换机还可以通 过网络侧网关以及用户侧网关向被叫用户终端发送来电显示信号,即主叫用户 的号码。

需要说明的是, 在实际应用中, 来电显示信号既可以作为语音控制信号, 也可以作为语音数据信号。
当来电显示信号作为语音数据信号时, 该来电显示信号由 TDM交换机产 生, 并通过网络侧网关以及用户侧网关下发至被叫用户终端; 当来电显示信号作为语音控制信号时, TDM交换机通过特征控制信息控 制用户侧网关生成, 之后由用户侧网关发送给用户终端。
本实施例中, TDM交换机通过特征控制信息控制用户侧网关生成来电显 示信号的过程大致可以为:
TDM交换机生成来电显示号码, 将该来电显示号码通过 Z接口发送至网 络侧网关, 网络侧网关可以识别并解析 TDM交换机发送的来电显示号码, 之 后打包成 IP报文发送给用户侧网关, 用户侧网关收到 IP报文后解析控制字段 获知需要发送来电显示信号, 则用户侧网关从 IP 文中读取来电显示号码, 生成来电显示信号, 并向用户终端发送该来电显示信号。

611 ~ 613、 被叫挂机过程。
若在语音通信过程中,被叫用户挂断电话, 则被叫用户终端可以发出挂机 信号 , 并经过用户侧网关以及网络侧网关到达 TDM交换机 , 由 TDM交换机 进行相应的拆线处理,挂机信号的具体传输处理过程与前述图 5所示实施例中 步骤 515 ~ 517描述的过程类似, 此处不再赘述。
本实施例中, 用户侧网关与网络侧网关可以通过 IP接口, 使用 IP网络进 行语音信号的传输, 本发明实施例的技术方案充分利用了 IP网络以实现语音 业务的拉远, 由于 IP网络具有网络成熟、 覆盖面广等特点, 因此能够有效的 降低数据传输的成本;
此外, TDM交换机可以向主叫用户终端发送反极性信号, 从而能够进行 精准计费。 上述实施例中仅以主叫流程和被叫流程对本发明数据处理方法进行了描 述, 可以理解的是, 语音业务中其他流程的处理方式与上述描述的方式类似, 此处不再赘述。

IP接收单元 701接收到 IP报文之后 ,校验单元 702会判断该 IP报文中是 否包含有控制特征信息,该控制特征信息用于指示数据处理网关所需进行的操 作, 若包含, 则获取单元 703可以根据该控制特征信息在预置的对应关系中获 取对应的语音控制信号。 需要说明的是, 第二数据处理网关中预先配置有 "控制特征信息与语音控 制信号" 之间的对应关系, 具体的对应关系可以如前述表 1所示。
本实施例中, 第二数据处理网关通过自身 Z接口与第二 TDM设备相连, 所以当获取单元 703获取到语音控制信号之后, TDM控制单元 704可以通过 自身的 Z接口,根据该确定的语音控制信号对第二 TDM设备进行语音业务控 制。
若校验单元 702确定 IP报文中不包含控制特征信息, 则解析单元 705对 IP报文进行解析得到语音数据信号, 发送单元 706可以通过 Z接口, 将解析 单元 705解析得到的语音数据信号发送至第二 TDM设备。
本实施例中, 第二数据处理网关通过 Z接口与第二 TDM设备相连, 并通 过 IP接口与 IP网络相连 ,所以 IP接收单元 701可以从 IP网络接收到 IP报文 , 获取单元 703根据 IP报文中的控制特征信息确定对应的语音控制信号, 之后 TDM控制单元 704通过 Z接口, 根据语音控制信号对第二 TDM设备进行语 音业务控制,本实施例的技术方案充分利用了 IP网络以实现语音业务的拉远, 由于 IP网络具有网络成熟、 覆盖面广等特点, 因此能够有效的降低数据传输 的成本。

该语音信号可以是语音控制信号, 也可以是语音数据信号, 其中, 语音控 制信号用于对语音业务进行控制, 语音数据信号用于传输语音业务数据。
TDM接收单元 801从第一 TDM设备接收到语音信号之后,校验单元 802 可以判断该语音信号是语音控制信号,还是语音数据信号,如果确定该语音信 号是语音控制信号,则获取单元 803在预置的对应关系中获取该语音控制信号 对应的控制特征信息。
