图 4 为根据本发明在分组域内的终端实现电路域会话的方法流程 图。 实施本发明的方式
为使本发明的目的、 技术方案和优点更加清楚, 下面结合附图对本 发明作进一步的详细描述。
如图 2所示, 实现本发明的系统主要包括: 电路域网络 211、 分组 域网络 212、 PDSN 206、 AN 205以及 MSC ( plus ) 210。 其中, 电路域 网络 211包括: SMC 204、 HLR 203、 MSC/VLR 202以及 BSS 201。 分 组域网络 212包括: IMS SMC 209、 HSS 208以及 S-CSCF 207。 电路域 网络中的 MSC/VLR 202和分组域网络中的 S-CSCF 207通过 MSC( plus ) 210相连, 该 MSC ( plus ) 210为实现电路域网络和分组域网络间的控 制信令转发的移动交换功能实体, 在电路域内, 该 MSC ( plus ) 210的 功能与普通 MSC的功能相同; 在分组域内, 该 MSC ( plus ) 210的功能 与可以终结呼叫的 AS和 BCCF/MGW的功能相同。
基于上述网络框架, 当 MS在电路域内进行业务时, MS可以通过 电路域的短消息中心 (SMC ) 向分组域内的多媒体短消息中心 (IMS SMC )发送表示其自生在电路域内的短消息; 然后由多媒体短消息中心 通知 MSC ( plus )该 MS在电路域内; 当 S-CSCF需要向该 MS发送分 组会话时, 将该会话触发到 MSC ( plus )上。
当 MS在分组域内进行业务时, 可以同时监听电路域网络, 判断电 路域内是否有对自己的寻呼消息。 然而, 当 MS正在进行的分组域内会 话, 如: VT业务等对实时性的要求比较高时, 就有可能存在由于 MS 自身资源不足, 而无法对电路域网络进行监听的问题。 此时, 为了解决 上述问题, 可以釆取由 MS向电路域发起一个位置登记过程, 然后由电 路域记录该 MS在分组域进行业务。 当电路域中出现以该 MS为被叫的 会话, 如: VOIP呼叫时, 可以由电路域的 MSC/VLR将该会话路由到 MSC ( plus ), 然后可以由该 MSC ( lus )向分组域内的该 MS发送该会 话, 也可以使用 CSI业务方式通知该 MS进入电路域, 在电路域内进行 该会话如: 接听呼叫。
下面详细说明上述当 MS在电路域内时实现分組域会话的方法, 该 方法流程如图 3所示, 具体包括如下步骤:
步骤 301: MS通过 BSS在 MSC/VLR上进行电路域位置登记。 这里, 该 MS在电路域内进行的业务可以是该 MS作为主、 被叫进 行的语音业务或短消息业务等, 也可以只是在电路域内进行了位置登 记, 但没有进行业务连接。
步骤 302: 由该 MS向电路域的 SMC发送表示其自身在电路域内的 短消息。
其中, 在上述步骤 301和步骤 302中, 只是给出了 MS向 SMC发 送短消息的一种情形, 即在 MS进行初始电路域位置登记, 如开机时向 SMC发送短消息。 另外, 当该 MS 由分组域进入电路域后, 也需要向 SMC发送表示其在电路域内的短消息。
步骤 303: SMC将该短消息转发至 IMS SMCc
步骤 304: IMS SMC通知 MSC ( lus )。
在实际操作过程中, 为了实现上述步骤 302至步骤 304, 可以预先 设置一个特定标识, 并将该特定标识置于由 MS向 SMC所发送短消息 的目的号码位置, 而且该特定标识可以是 MSC ( plus )地址, 也可以是 一个特定号码或特定字符串, 其中该字符串可以是数字、 字母或它们的 组合等。 这样, 当 SMC接收到目的号码为上述特定号码的短消息时, 将该短消息直接转发给 IMS SMC。 IMS SMC接收到该短消息后, 识别 该短消息的目的号码为预先设定的特定标识, 将该短消息的发送端号码 通知 MSC( plus )。这里,为了使电路域内的 SMC和分组域内的 IMS SMC 能够识别出特定标识,可以在 SMC和 IMS SMC分别设置上述特定标识, 当 SMC和 IMS SMC接收到相应的短消息时,只需判断在预先约定的位 置处的标识, 如目的号码位置是否与自身设置的标识一致, 如果是, 则 判定需要通知 MSC ( plus ); 否则, 判定为普通短消息, 进行正常的转 发处理。
而且在上述步驟 304 中, IMS SMC 可以通过 SIP协议, 即订阅 ( SUBSCRIBE )机制通知 MSC ( plus ), 也可以通过其它方式通知 MSC ( lus )。
步骤 305: 当 S-CSCF需要与 MS进行分组域会话时,将该会话触发 到 MSC ( plus )上, 然后由 MSC ( plus )向电路域内的该 MS转发该会 话或通知该 MS进入分组域进行该会话。
在本步骤中, 当 S-CSCF将会话触发到 MSC ( plus )上之后, MSC
( plus )可以采取两种方式使得处于电路域内的该 MS实现分组域会话。 第一种: 直接将会话转发给电路域内的相应 MS, 通过电路域来承载该 分组域会话, 从而使得该 MS完成本次会话, 如 VOIP呼叫等。 此时, MSC ( plus )相当于普通的 MSC。 第二种: 当分组域呼叫, 如 VT等无 法使用电路域网络进行承载时, 可以由 MSC ( plus ) 向 IMS MSC发送 通知, 然后由 IMS MSC使用标准的 SMC接口协议向 SMC发送约定好 的某种特殊格式的短消息, 再由 SMC将该短消息转发至 MS。 当 MS接 收到该短消息后, 根据短消息中的主叫标识, 如预先设定的某一特定号 码; 以及业务类型等信息, 判断是否断掉当前的电路域连接来进行本次 分组域会话, 如果是, 则向 SMC发送表示进行本次分組域会话的应答 消息, 并断掉当前的电路域连接, 转到分组域, 根据短消息中的 MSC
( plus )地址以及呼叫标识, 通知 MSC ( plus )该 MS 已经接入分组域 网络, MSC ( plus ) 向 S-CSCF发起 redirect, 然后 S-CSCF将会话下发 给该 MS, 由该 MS进行本次分组域会话。 上述实施例阐述了当 MS在电路域内时, 接收分组域会话的过程。 该过程需要 MS向分组域发送表示其自身在电路域内的短消息, 如果分 组域存在对该 MS的分组域会话时, 可以将该会话触发到 MSC ( plus ) 上, 然后由 MSC ( plus )通过电路域实现相应的分组域业务, 或者由 MSC ( plus )通知电路域内的该 MS进入分组域进行该会话。
以上说明了当 MS在电路域内时, 实现分组域会话的方法, 下面详 细说明当 MS在分组域内时实现电路域会话的方法。 通常, 在资源充足 的情况下, 在分组域内的 MS可以同时监听电路域网絡, 判断电路域内 是否有寻呼自身的会话请求, 如果有 , 则直接切换到电路域内进行相应 的电路域会话, 也可以直接通过 MSC ( plus )将电路域会话, 如 VOIP 呼叫等直接转发给该 MS, 由该 MS在分组域内, 即利用分组域的承载 完成本次电路域会话。 然而, 当 MS在自身资源不足的情况下, 则无法 监听电路域网络。 例如: 当 ] IS正在分组域内进行视频业务时, 由于视 频业务对实时性要求比较高, 通常占用的系统资源比较多, 以致 MS无 法亲自监听电路域网络。 此时, 可以采取由 MS向 MSC ( plus )发送其 自身处于分组域内的短消息, 从而使电路域会话, 如寻呼消息等可以通 过分组域网絡下发给该 MS。
在上述方案中, 出于性能的考虑, 也可以在分组域网絡中设置专门 的 IMS MSC,该 IMS MSC可以直接与电路域的 MSC/VLR和 HLR相连, 并且该 IMS MSC还与 MSC ( plus )相连, 从而使得 MS可以直接通过 该 IMS MSC向 MSC ( plus )发送短消息, 而无需通过电路域的 SMC转 发。
下面说明当 MS在分组域内时实现电路域会话的方法, 其流程如图 4所示, 具体包括如下步骤:
步驟 401: 当 MS在分组域内进行位置登记后, 向 MSC ( plus )发 送表示其自身在分组域内的短消息。
其中, 向移动交换功能实体发送通知的步骤包括: 当 MS在分组域 注册后, 通过第三方注册流程通知所述 MSC ( plus ), 并且 MSC ( plus ) 通过 SUBSCRIB机制从 MS获取关于该 MS是否在分组域内的状态信 息。 并且 MS是通过 AN、 PDSN和 S-CSCF向 MSC ( plus )发送其自身 当前在分组域内的短消息的。
步骤 402: 会话发起端的 MSC/VLR使用标准的电路域路由方式将 会话路由到 MSC ( plus
步骤 403: MSC ( plus )根据接收到的上述步骤 401 中所述的 MS 在电路域内的短消息判定该 MS当前处于电路域内, 从而向该 MS发起 诸如 VOIP呼叫等会话, 并通过 S-CSCF、 PDSN和 AN将该会话发送至 MS, 或者由该 MSC ( plus )使用 CSI业务方式通知 MS进入电路域, 使该 MS在电路域内进行本次会话。
例如:在上述流程中,当电路域内有向该 MS发送的短消息时, SMC 可以将该短消息转发至 MSC ( plus ), 然后由 MSC ( plus )使用标准的 分组短消息业务将该短消息下发给 MS。
总之, 以上所述仅为本发明的较佳实施例而已 , 并非用于限定本发 明的保护范围。
