Description

一种呼叫方法、 装置及系统
技术领域 本发明涉及通信技术领域, 尤其涉及一种呼叫方法、 装置及系统。
背景技术
在 FTTx ( Fiber to the x, 光纤到 x ) 网络中, 处于用户侧的 ONU ( Optical Network Unit, 光网络单元)设备负责提供语音业务。 用户的模拟语音信号通过 ONU转为 RTP ( Real-Time Transport Protocol, 实时传输协议 )数据流, 通过 PON 光线路终端) , 再由 OLT转发至 IP网络。
语音业务做为基础电信服务, 一些国家或者组织要求固定电话用户要有能 力建立基于语音或者文本的紧急呼叫。 但是从 FTTx网络的特点来看, 语音网关 功能下移至用户侧的 ONU设备上, 不可避免的会带来一些语音设备的可靠性问 题, 如用户误改 ONU设备的配置信息, 或者语音业务配置信息丟失、 普通语音 业务受限等问题, 在这种情况下会面临正常语音功能不可用的问题。
很多国家规定电信网络应提供应急和容灾的机制, 确保最基本的语音业务 (如火警, 急救等) 的通畅。 为了满足这种规定, 需要一种机制来确保在 ONU 设备上能提供最基本的紧急呼叫服务, 即使在 ONU处于故障或业务受限的情况 下。

步骤 205 , 判断用户的呼叫是否为紧急呼叫, 如果是, 执行步骤 210 , 否则 执行步骤 230。
终端设备可以根据本地配置的紧急逃生数图对用户的呼叫号码进行匹配, 从而判断用户的呼叫是否为紧急呼叫。
步骤 210, 向接入设备发送紧急呼叫请求。
参见图 1 , 终端设备 10可以通过向接入设备 12发送 OAM ( Operation, Administration and Maintenance, 操作、 管理和维护)报文, 或者 OMCI ( Optical Network Terminal Management and Control Interface , 光网络终端管理控制接口) 消息来携带紧急呼叫请求。

态配置的 IP地址掩码; k
否则, 该字段无效, 取 值为 0x00 当 Voice ip Mode: iadDefault
0x00时,表示 ONU的静 GW
态配置的 IAD默认网关
接入设备将紧急呼叫资源信息发送给终端设备后, 还可以将该紧急呼叫资 源设置成占用状态。 步骤 220, 根据提取的应急 MGC的配置信息向应急 MGC注册。
终端设备收到接入设备的紧急呼叫资源信息后, 提取紧急呼叫资源信息中 的应急 MGC的配置信息, 利用应急 MGC的配置信息向应急 MGC注册。
如果紧急呼叫资源信息中包含有语音接口 IP和默认网关, 则终端设备利用 下发的语音接口 IP和默认网关配置本地语音接口, 釆用配置的语音接口向应急 MGC注册;如果紧急呼叫资源信息中没有包含语音接口 IP和默认网关,终端设 备则用当前语音接口的 IP和当前默认网关向应急 MGC注册。 终端设备利用应急 MGC的配置信息向应急 MGC注册的过程,以应急 MGC 的配置信息包括应急 MGC的 IP地址、 端口号、 注册方式以及终端标识作为举 例, 具体可以包括:

终端设备可以釆用 OMCI消息或者 OAM报文上报释放紧急呼叫资源的请 求消息, 其中釆用 OMCI消息的格式 如表 5所示:
Figure imgf000010_0001
Figure imgf000010_0002
终端设备也可以釆用 OAM报文上报释放紧急呼叫资源的请求消息, OAM 报文的格式可以如表 6所示: 表 6
Figure imgf000011_0001
终端设备上报释放紧急呼叫资源的请求消息后, 可以在本地删除紧急呼叫 资源。
接入设备收到释放紧急呼叫资源的请求消息后, 可以将相应的紧急呼叫资 源的状态设置为空闲。
