为了更清楚地说明本发明实施例或现有技术中的技术方案, 下面将对实 施例或现有技术描述中所需要使用的附图作一筒单地介绍, 显而易见地, 下 面描述中的附图是本发明的一些实施例, 对于本领域普通技术人员来讲, 在 不付出创造性劳动性的前提下, 还可以根据这些附图获得其他的附图。

为使本发明实施例的目的、 技术方案和优点更加清楚, 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做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。
图 1为本发明模拟终端的事件上报方法实施例流程图。本发明实施例中 模拟终端接入设备可为 SIP IAD, 模拟终端可为 SIP IAD下挂的模拟话机和 传真机等。 如图 1所示, 本实施例包括:
步骤 11 : 模拟终端接入设备感知模拟终端的线路电压变化。
步骤 12:模拟终端接入设备根据感知到的所述模拟终端的线路电压变化 信息,确定模拟终端触发的动作事件,并向服务器上报模拟终端的动作事件。 模拟终端接入设备的下行端口连接有多个模拟终端,通过与模拟终端连 接的端口的电压变化, 可感知模拟终端上的线路电压变化。 根据线路电压变 化信息, 确定模拟终端触发的动作事件, 并实时向 SIP服务器上报。
例如, 模拟话机 A摘机时, 播放信号音, 与模拟话机 A连接的端口的 电压由高变低。 在 SIP IAD感知该端口的电压由高变低时, 确定模拟话机 A 触发了摘机事件,实时将模拟话机 A的摘机事件上报给 SIP服务器。又例如, 模拟话机 B挂机时, 播放忙音, 与模拟话机 B连接的端口的电压由低变高。 在 SIP IAD感知该端口的电压由低变高时,确定模拟话机 A触发了挂机事件, 实时将模拟话机 B的挂机事件上报给 SIP服务器。
本发明实施例中 SIPIAD实时感知下挂的各模拟终端的动作事件并上报 给 SIP服务器, 因而 SIP服务器在模拟终端发生动作事件的时间段可实时获 知各模拟终端的状态变化, 从而使得 SIP服务器保存的各模拟终端的状态与 各模拟终端的实际状态始终保持一致, 进而以便于 SIP服务器可正确触发状 态类增值业务, 如立即热线、 延迟热线、 遇忙呼叫前转等业务, 也可根据模 拟终端的实际状态对模拟终端进行有效监控。
图 2为本发明模拟终端的状态信息获取方法实施例一流程图。如图 2所 示, 本实施例包括:
步骤 21: SIP服务器接收模拟终端接入设备上报的模拟终端的动作事件。 步骤 22: SIP服务器根据接收到的模拟终端的动作事件, 更新保存的模 拟终端的状态信息。
SIP服务器接收到模拟终端的动作事件后, 实时更新保存的该模拟终端 的状态信息。 例如, SIP服务器接收到模拟终端接入设备上报的模拟话机摘 机事件时, 将模拟话机 A的状态信息更新为忙状态。 又例如, SIP服务器接 收到模拟终端接入设备上报的模拟话机 B挂机事件时, 将模拟话机 B的状 态信息更新为空闲状态。由于 SIP IAD实时将模拟终端的动作事件上报给 SIP 服务器, 因此 SIP服务器在模拟终端发生动作事件的时间段可实时获知各模 拟终端的状态变化,从而可以进一步为模拟终端触发正确的业务。例如, SIP 服务器在接收到所述模拟终端接入设备上报的摘机事件时, 若接收到呼叫所 述模拟终端的呼叫请求, 为所述模拟终端触发遇忙前转业务。 又例如, 在接 收到所述模拟终端接入设备上报的摘机事件时,为所述模拟终端触发立即热 线业务。
本实施例避免了现有技术中在模拟终端发生动作事件的时间段由于模 拟终端实际状态与 SIP服务器保存的状态不一致, 可能导致的不能正确触发 相关业务的缺陷。
以下通过实施例二说明 SIP服务器如何根据保存的各模拟终端的状态信 息, 处理与状态有关的业务。
图 3A为本发明模拟终端的状态信息获取方法实施例二信令图, 图 3B 为本发明模拟终端的状态信息获取方法实施例二应用场景图。如图 3B所示, SIP综合接入设备下挂有已在 SIP服务器上注册的模拟话机 A和模拟话机 B , SIP综合接入设备上行接入 SIP服务器, SIP服务器通过网关与公共交换电 话网络( Public Switched Telephone Network, PSTN )连接。 话机 C通过程控 交换 ( Private Branch Exchange, PBX )设备接入 PSTN网络。
如图 3A所示, 本实施例包括:
步骤 la: 模拟话机 A摘机。
在初始状态时,模拟话机 A空闲, SIP服务器保存的模拟话机 A的状态 信息为 "空闲状态" , 两者一致。
步骤 2a: SIP IAD感知到与模拟话机 A连接的端口的电压由高变低。 步骤 3a: SIP IAD确定模拟话机 A触发了摘机事件, 将模拟话机 A的 摘机事件上报给 SIP服务器。
SIP IAD向 SIP服务器上报的模拟话机 A的摘机事件可通过 SIP Info信 息或 SIP Notify信息承载,但不限于以上信息。若通过 SIP Info信息承载时, SIP服务器会向 SIP IAD返回摘机事件上报成功的 SIP Info消息。
以下说明 SIP IAD通过 Info消息向 SIP服务器上报摘机事件时, SIP IAD发 送的具体消息内容:
INFO sip:#***@ 10.166.50.180:5060;user=phone SIP/2.0

10.166.56.63:5060;branch=z9hG4bK545b046dd54a216f282f6454b

Max- Forwards: 70
Content-Length: 50
Content-Type: application/HookEvent
event-type=onhookReq
SIP IAD通过以上消息中 Content-Type和 event-type向 SIP服务器上报 模拟话机的动作事件, 其中, Content-Type所指的 application/HookEvent, 将 此次消息的内容类型自定久为事件, event-type所指的 onhookReq表示此次 消息上报的事件类型为摘机事件。
步骤 4a: SIP服务器接收到 SIP IAD上报的模拟话机 A摘机事件后, 更 新模拟话机 A的状态信息为忙状态。
SIPIAD感知到模拟话机 A摘机时, 表明模拟话机 A正主动发起呼叫或 正要被动接收呼叫,因此 SIP服务器将模拟话机 A的状态信息从 "空闲状态" 更新为 "忙状态" , 从而 SIP服务器保存的模拟话机 A的状态信息与模拟 话机 A的实际状态与一致。
步骤 5a: SIP服务器为模拟话机 A触发立即热线业务。
若模拟话机 A定制了立即热线业务,在 SIP服务器接收到 SIP IAD上报 的模拟话机 A摘机事件后, 为模拟话机 A触发立即热线业务。
步骤 6a: 在接收到上报的模拟话机 A摘机事件时, SIP服务器接收到模 拟话机 B或话机 C发起的呼叫模拟话机 A的呼叫请求。 步骤 7a: SIP服务器为模拟话机 A触发遇忙前转业务。
SIP服务器接收到上报的模拟话机 A摘机事件后,将模拟话机 A的状态 更新为 "忙状态" , 与此同时接收到模拟话机 B或话机 C呼叫模拟话机 A 的呼叫请求, 由于, 此时 SIP服务器已获知模拟话机 A摘机, SIP服务器中 保存的拟话机 A状态已更新为忙状态, 在模拟话机 A定制了遇忙前转业务 的情况下, SIP服务器立即为模拟话机 A正确触发遇忙业务, 使该呼叫请求 转接到模拟话机 A设定的话机上。而在现有技术中 SIP服务器无法获知模拟 话机的摘机事件, 在模拟话机 A摘机时若模拟话机 B或终端发起呼叫模拟 话机 A的请求, SIP服务器中保存的模拟话机 A的状态仍为空闲状态, SIP 服务器向模拟话机 A发起呼叫请求。 而此时实际上模拟话机 A正处于摘机 状态, 导致呼叫失败, 从而不能为模拟话机正确触发遇忙前转业务。
步骤 8a: 模拟话机 A挂机。
步骤 9a: SIP IAD感知到与模拟话机 A连接的端口的电压由低变高。 步骤 10a: SIPIAD确定模拟话机 A触发了挂机事件, 将模拟话机 A的 挂机事件上报给 SIP服务器。
以下说明 SIP IAD通过 Info消息向 SIP服务器上报挂机事件时, SIP IAD发 送的具体消息内容:
INFO sip:#***@ 10.166.50.180:5060;user=phone SIP/2.0

Max- Forwards: 70
Content-Length: 50
Content-Type: application/HookEvent event-type=offhookReq
SIP IAD通过以上消息中 Content-Type和 event-type向 SIP服务器上报 模拟话机的动作事件, 其中, Content-Type所指的 application/HookEvent, 将 此次消息的内容类型自定久为事件, event-type所指的 offliookReq表示此次 消息上报的事件类型为摘机事件。
步骤 11a: SIP服务器接收到 SIP IAD上报的模拟话机 A挂机事件后, 更新模拟话机 A的状态信息为空闲状态。
SIPIAD感知到模拟话机 A挂机时, 表明模拟话机 A已结束主动发起的 呼叫或被动接收的呼叫, 此时可接收其它终端的呼叫请求。 因此, SIP R务 器将模拟话机 A的状态信息从 "忙状态" 更新为 "空闲状态" , 从而 SIP服 务器保存的模拟话机 A的状态信息与模拟话机 A的实际状态保持一致。
步骤 12a: 在接收到上报的模拟话机 A挂机事件后, SIP服务器接收到 模拟话机 B或话机 C发起的呼叫模拟话机 A的呼叫请求。
步骤 13a: SIP服务器向模拟话机 A发起呼叫请求, 呼叫成功。
在模拟话机 A挂机时刻, 模拟话机 B或话机 C向 SIP服务器发起了呼 叫模拟话机 A的呼叫请求, SIP服务器根据保存的模拟话机 A的空闲状态, 及时向模拟话机 A发起呼叫请求。 由于模拟话机 A实际也处于空闲状态, 因此呼叫成功。 而在现有技术中 SIP服务器无法获知模拟话机的挂机事件, 在模拟话机 A挂机时刻当模拟话机 B或终端发起呼叫模拟话机 A的请求时, 由于 SIP服务器中保存的模拟话机 A的状态仍为忙状态, SIP服务器不向模 拟话机 A发起呼叫请求。 而此时实际上模拟话机 A正处于挂机状态, 从而 没有为模拟话机正确触发呼叫业务。
本发明实施例, SIP服务器根据实时获知的模拟终端发生的摘机事件或 挂机事件, 实时更新模拟话机的状态信息。 使得在模拟终端发生的摘机事件 或挂机事件时刻, SIP服务器保存的状态信息与模拟话机的实际状态保持一 致, 从而在模拟话机发生摘机事件或挂机事件时, 可正确为模拟话机触发立 即热线或遇忙前转等状态业务。 图 4为本发明模拟终端接入设备实施例结构示意图。本实施例中模拟终 端接入设备具体可为 SIP IAD。 如图 4所示, 本实施例包括: 感知模块 41 和上报模块 42。
