实施例一、 能力信息上报方法。 该方法的流程如附图 1所示。
图 1中, S100、 建立业务的移动交换中心向终端发送是否支持宽带自适 应多速率能力的指示信息。 该指示信息用于通知终端是否向移动交换中心 上报宽带自适应多速率能力信息。 该指示信息可以表示出建立业务的移动 交换中心是否支持宽带自适应多速率能力, 该指示信息也可以表示出移动 交换中心是否允许终端上报宽带自适应多速率能力的指示信息, 因此, 上 述移动交换中心是否支持宽带自适应多速率能力的指示信息也可以称为是 否允许终端上报宽带自适应多速率能力的指示信息。 下述实施例中筒称为 指示信息。
在 S100中, 建立业务的移动交换中心可以主动向终端发送指示信息。 移动交换中心主动发送指示信息即: 建立业务的移动交换中心在没有接收 到相关请求的情况下, 向终端发送指示信息。 这里的相关请求为用于请求 上报能力信息的请求, 也即用于请求上述指示信息的请求。
S100中的建立业务的移动交换中心也可以被动的向终端发送指示信 息, 即移动交换中心在接收到终端发送来的请求上报能力信息后, 根据该 请求上报能力信息向终端发送移动交换中心是否支持宽带自适应多速率能 力的指示信息。
不论移动交换中心是主动向终端发送指示信息 , 还是被动向终端发送 指示信息, 移动交换中心均可以在终端向移动交换中心发送 Setup (建立) 消息或发送 Call Confirm (呼叫确认) 消息之前, 向终端发送指示信息。 移 动交换中心可以利用向终端发送的现有消息中的现有字段来实现指示信息 的发送, 移动交换中心也可以利用新增的消息向终端发送指示信息。 在利用现有消息中的现有字段向终端发送指示信息时, 一个具体的例 子为: 移动交换中心利用连接管理服务接受消息或者加密模式命令中的现 有字段的空闲比特来携带指示信息, 并向终端发送连接管理服务接受消息 或者加密模式命令。
在利用新增的消息向终端发送指示信息时, 移动交换中心可以直接向 终端发送该新增消息, 即新增消息单独发送, 也就是说, 该新增消息不会 携带在其它消息的信元中。 移动交换中心也可以将新增消息作为独立的信 元携带在移动交换中心向终端发送的其它消息中, 并向终端发送该其它消 息, 即在其它消息中增加新信元以携带该新增消息。 另外, 移动交换中心 还可以将新增消息携带在移动交换中心向终端发送的其它消息的原有信元 中。 为方便描述, 上述增加的新信元和携带新增消息的原有信元均可以称 为是否支持宽带自适应多速率能力的指示信息专用信元, 在本实施例中简 称为指示信息专用信元。 需要说明的是, 指示信息专用信元可以仅携带上 述新增消息, 也可以携带上述新增消息和其它信息, 指示信息专用信元仅 是为了后续描述方便对携带新增消息的信元冠以的一种名称而已。 本实施 例不限制移动交换中心向终端发送指示信息的具体实现方式。
移动交换中心主动向终端发送指示信息的一个具体例子为: 在终端为 主叫终端的情况下, 移动交换中心可以在向终端发送 Connection Management (连接管理, CM )服务接受消息或者加密模式命令之前主动向 终端发送指示信息; 移动交换中心也可以在向终端发送 CM服务接受消息或 者加密模式命令的同时主动向终端发送指示信息, 即移动交换中心可以将 指示信息携带在 CM服务接受消息或者加密模式命令的指示信息专用信元 中, 并向终端发送。
移动交换中心主动向终端发送指示信息的另一个具体例子为: 在终端 为被叫终端的情况下, 移动交换中心可以在向终端发送建立消息之前主动 向终端发送指示信息; 移动交换中心也可以在向终端发送建立消息的同时 主动向终端发送指示信息, 即移动交换中心将指示信息携带在建立消息的 指示信息专用信元中, 并向终端发送该建立消息。
移动交换中心被动向终端发送指示信息的一个具体例子为: 移动交换 中心在接收到终端发送来的请求上报能力信息之后、 且在终端向移动交换 中心发送建立消息或呼叫确认消息之前, 移动交换中心向终端发送指示信 息。 同样的, 移动交换中心可以在向终端发送 CM服务接受消息或者加密模 式命令或者建立消息之前被动向终端发送指示信息; 移动交换中心也可以 在向终端发送 CM服务接受消息或者加密模式命令或者建立消息的同时被 动向终端发送指示信息。
终端向移动交换中心发送的请求上报能力信息可以通过终端向移动交 换中心发送的现有消息的现有字段发送, 也可以利用新增消息向移动交换 中心发送。
在终端利用现有消息的现有字段向移动交换中心发送请求上报能力信 息时, 一个具体例子为: 终端利用连接管理服务请求消息中的现有字段的 空闲比特来携带请求上报能力信息, 并向移动交换中心发送连接管理服务 请求消息。
在终端利用新增消息向移动交换中心发送请求上报能力信息时, 终端 可以直接发送该新增消息, 终端也可以将新增消息作为独立的信元携带在 终端向移动交换中心发送的现有消息中, 并向移动交换中心发送该消息, 即在终端向移动交换中心发送的现有消息中增加新信元, 以携带该新增消 息, 这里的现有消息如连接管理服务请求消息等。 另外, 终端也可以将请 求上报能力信息携带在终端向移动交换中心发送的其它消息的原有信元 中。 为方便描述, 终端向移动交换中心发送的消息中的携带新增消息的信 元可以称为请求上报能力信息专用信元。 同样的, 请求上报能力信息专用 信元可以仅携带新增消息, 也可以携带新增消息和其它信息。 本实施例不 限制终端向移动交换中心发送请求上报能力信息的具体实现方式。 移动交换中心接收到终端发送来的请求上报能力信息后, 移动交换中 心可以在其支持宽带自适应多速率的情况下, 向终端发送表示允许上报宽 带自适应多速率能力的指示信息, 此时的指示信息还可以表示出移动交换 中心支持宽带自适应多速率能力。 如果移动交换中心不支持宽带自适应多 速率, 则移动交换中心可以不向终端发送指示信息。 当然, 在移动交换中 心不支持宽带自适应多速率的情况下, 移动交换中心也可以向终端发送表 示不允许上报宽带自适应多速率能力的指示信息, 此时的指示信息还可以 表示出移动交换中心不支持宽带自适应多速率能力。
需要特别说明的是, 在移动交换中心不支持宽带自适应多速率的情况 下, 移动交换中心可能不能有效识别终端发送来的请求上报能力信息, 移 动交换中心可以直接丢弃接收到的请求上报能力信息。 这样, 移动交换中 心不会向终端发送是否支持宽带自适应多速率能力的指示信息。 终端在发 送了请求上报能力信息后, 如果在发送 Setup消息或发送 Call Confirm消息 时, 仍没有接收到移动交换中心发送来的指示信息, 则终端可以确定出移 动交换中心不允许上报宽带自适应多速率能力信息, 从而终端不会向移动 交换中心上 宽带自适应多速率能力信息。
本实施例还可以可选的包括 S110: 移动交换中心接收终端根据指示信 息上报的宽带自适应多速率能力信息。 终端上报的宽带自适应多速率能力 信息为: 终端确定出接收到的指示信息表示移动交换中心允许上报宽带自 适应多速率能力后, 向移动交换中心上 >¾的宽带自适应多速率能力信息。 这里的终端为支持宽带自适应多速率能力的终端。
需要说明的是, 如果终端接收到移动交换中心发送来的指示信息, 且 确定出接收到的该指示信息表示移动交换中心不允许上报宽带自适应多速 率能力信息 , 则终端不会向移动交换中心上 ^艮宽带自适应多速率能力信息 , 从而避免了在移动交换中心不支持宽带自适应多速率能力的情况下, 因终 端上报宽带自适应多速率能力信息而引起的呼叫失败现象。 在 S 1 10中, 终端向移动交换中心发送的宽带自适应多速率能力信息可 以通过终端向移动交换中心发送的现有消息的现有字段发送, 也可以利用 新增消息向移动交换中心发送。
在终端利用现有消息的现有字段向移动交换中心发送宽带自适应多速 率能力信息时, 一个具体例子为: 终端利用建立消息中的现有字段的空闲 比特来携带宽带自适应多速率能力信息, 并向移动交换中心发送建立消息。
在终端利用新增消息向移动交换中心发送宽带自适应多速率能力信息 时, 终端可以直接发送该新增消息, 终端也可以将新增消息作为独立的信 元携带在终端向移动交换中心发送的现有消息中, 并向移动交换中心发送 该消息, 即在终端向移动交换中心发送的现有消息中增加新信元, 以携带 该新增消息, 这里的现有消息如建立消息或者呼叫确认消息等。 另外, 终 端也可以将宽带自适应多速率能力信息携带在终端向移动交换中心发送的 其它消息的原有信元中。 为方便描述, 终端向移动交换中心发送的消息中 的携带新增消息的信元可以称为宽带自适应多速率能力信息专用信元。 同 样的, 宽带自适应多速率能力信息专用信元可以仅携带新增消息, 也可以 携带新增消息和其它信息。 本实施例不限制终端向移动交换中心发送宽带 自适应多速率能力信息的具体实现方式。
移动交换中心接收终端上报的宽带自适应多速率能力信息的一个具体 的例子为: 移动交换中心接收终端发送来的建立消息, 并从建立消息的承 载能力信元的 SPEECH VERSION字段中获取终端上报的宽带自适应多速率 能力信息。 移动交换中心接收终端上报的宽带自适应多速率能力信息的另 一个具体的例子为: 移动交换中心接收终端发送来的建立消息或者呼叫确 认消息, 并从消息携带的新增信元中获取终端上报的宽带自适应多速率能 力信息。 本实施例不限制移动交换中心从终端发送来的消息中获取终端上 报的宽带自适应多速率能力信息的具体实现方式。
从上述针对实施例一的描述可知 , 通过使移动交换中心向终端发送指 示信息, 使终端可以根据移动交换中心发送来的信息明确获知是否需要向 移动交换中心上报宽带自适应多速率能力信息, 另外, 由于实施例一中的 移动交换中心只有在支持宽带自适应多速率能力的情况下才会接收到终端 上报的宽带自适应多速率能力信息, 因此, 实施例一能够在不需要对基站 控制器进行升级的情况下, 避免呼叫失败现象。 在采用 MSC资源池^^术时, 尽管一个 BSC可以连接到 MSC资源池中的任意一个 MSC, 但是, 由于指示 信息是由呼叫中的移动交换中心向终端下发的, 因此, 实施例一可以针对 一个具体的呼叫为终端正确指示出是否向移动交换中心上报宽带自适应多 速率能力, 从而避免了采用 MSC资源池技术时, 终端要么都上报宽带自适 应多速率能力信息而引起的呼叫失败现象、 以及终端要么都不上报宽带自 适应多速率能力信息而引起的不能有效利用终端的宽带自适应多速率能力 的现象; 另外, 由于实施例一中的指示信息是从移动交换中心向终端发送 的, 因此,避免了通过 Packet SI Status消息下发 SI3时由于基站控制器不支持 Packet SI Status消息而导致的呼叫失败现象。
实施例二、 能力信息上 方法。 该方法的流程如附图 2所示。
图 2中, S200、 在建立电路域业务过程中, 基站控制器将移动交换中心 是否支持宽带自适应多速率能力的指示信息通过层三信令向终端发送。 这 里的指示信息用于通知终端是否向移动交换中心上报宽带自适应多速率能 力信息, 该指示信息可以表示出移动交换中心是否支持宽带自适应多速率 能力。
基站控制器可以通过预先设置信息等方式获知与其连接的移动交换中 心是否支持宽带自适应多速率能力。
基站控制器可以利用建立电路域业务过程中现有的层三信令中的空闲 比特位来发送上述指示信息, 基站控制器也可以利用新增的消息向终端发 送指示信息, 即基站控制器将新增的消息携带在层三信令的指示信息专用 信元中, 并向终端发送该层三信令。 基站控制器利用现有消息中的字段发送指示信息的一个具体的例子 为: 基站控制器将指示信息携带在立即指配消息的空闲比特中, 并向终端 发送立即指配消息。
基站控制器在利用新增的消息向终端发送指示信息时, 基站控制器可 以将新增的消息作为独立的信元携带在基站控制器向终端发送的层三信令 中, 并向终端发送该层三信令。 该独立的信元可以称简称为指示信息专用 信元。 本实施例不限制基站控制器在建立电路域业务过程中利用层三信令 向终端发送指示信息的具体实现方式。
在利用新增的消息向终端发送指示信息时, 基站控制器可以直接向终 端发送该新增消息, 即该新增消息为层三信令且该层三信令为新增的信令; 基站控制器也可以将新增消息作为独立的信元携带在基站控制器向终端发 送的现有层三信令中, 并向终端发送, 即在现有层三信令中增加新信元以 携带该新增消息, 现有层三信令如立即指配消息。 另外, 基站控制器还可 以将新增消息携带在基站控制器向终端发送的现有层三信令的原有信元 中。 为方便描述, 上述增加的新信元和携带新增消息的原有信元均可以称 为是否支持宽带自适应多速率能力的指示信息专用信元, 在本实施例中简 称为指示信息专用信元。 需要说明的是, 指示信息专用信元可以仅携带上 述新增消息, 也可以携带上述新增消息和其它信息, 指示信息专用信元仅 是为了后续描述方便对携带新增消息的信元冠以的一种名称而已。 本实施 例不限制基站控制器向终端发送指示信息的具体实现方式。
在基站控制器通过层三信令向终端发送指示信息后, 终端判断出接收 到的指示信息表示移动交换中心允许上 >¾宽带自适应多速率能力信息, 则 终端向移动交换中心上报宽带自适应多速率能力信息, 终端可以利用现有 消息的现有字段向移动交换中心发送宽带自适应多速率能力信息, 终端也 可以利用新增消息向移动交换中心发送; 如果终端判断出接收到的指示信 息表示移动交换中心不允许上报宽带自适应多速率能力信息, 则终端不会 向移动交换中心上报宽带自适应多速率能力信息, 从而避免了在移动交换 中心不支持宽带自适应多速率能力的情况下, 因终端上报宽带自适应多速 率能力信息而引起的呼叫失败现象。
从上述针对实施例二的描述可知, 基站控制器通过利用层三信令向终 端发送指示信息, 使终端可以根据基站控制器发送来的层三信令明确获知 是否需要向移动交换中心上报宽带自适应多速率能力信息, 从而实施例二 能够避免呼叫失败现象; 另外, 由于指示信息是基站控制器通过层三信令 向终端发送的, 因此, 即便是终端处于分组传输模式时建立语音业务, 实 施例二中的基站控制器也能够将指示信息成功发送至终端, 从而避免了通 过 Packet SI Status消息下发 SI3时由于基站控制器不支持 Packet SI Status消息 而导致的呼叫失败现象。
实施例三、 能力信息上报方法。 该方法的流程如附图 3所示。
图 3中, S300、 终端将宽带自适应多速率能力信息携带在消息的新增信 元中, 并向移动交换中心发送该消息。 这里的新增信元能够被支持宽带自 适应多速率能力的移动交换中心识别, 且不能够被不支持宽带自适应多速 率能力的移动交换中心识别。 这里的终端为支持宽带自适应多速率能力的 终端。
在 S300中 , 终端可以在接收到基站控制器或者移动交换中心发送来的 移动交换中心是否支持宽带自适应多速率能力的指示信息, 且根据该指示 信息判断出允许上报宽带自适应多速率能力信息后, 再将宽带自适应多速 率能力信息携带在消息的新增信元中, 并向移动交换中心发送该消息。 另 外, 终端也可以在没有接收到基站控制器和移动交换中心发送来的指示信 息的情况下, 主动的将宽带自适应多速率能力信息携带在消息的新增信元 中, 并向移动交换中心发送该消息。
上述消息中的新增信元可以仅携带宽带自适应多速率能力信息, 也可 以携带宽带自适应多速率能力信息和其它信息。 上述新增信元可以称为宽 带自适应多速率能力信息专用信元, 同样的, 本实施例中的宽带自适应多 速率能力信息专用信元并不是特指该信元中仅携带宽带自适应多速率能力 信息。
不论是终端主动发送上述携带新增信元的消息, 还是被动的根据接收 到的指示信息发送上述携带新增信元的消息, 终端向移动交换中心发送的 消息可以是建立消息或者呼叫确认消息等。 当然, 终端也可以利用向移动 交换中心发送的其他消息携带上述新增信元 , 本实施例不限制携带上述新 增信元的具体消息名称。
从上述针对实施例三的描述可知 , 终端通过利用携带有新增信元的消 息向移动交换中心上 ^艮宽带自适应多速率能力信息, 由于移动交换中心在 不支持宽带自适应多速率能力信息的情况下, 移动交换中心不能够有效识 别该新增信元, 从而会丢弃该新增信元, 因此, 实施例三能够避免呼叫失 败现象; 在终端主动发送携带有新增信元的消息的情况下, 不但不需要对 基站控制器进行升级, 而且,还避免了通过 Packet SI Status消息下发 SI3时由 于基站控制器不支持 Packet SI Status消息而导致的呼叫失败现象。
实施例四、 能力信息上 方法。 该方法的流程如附图 4所示。
图 4 中, S400、 基站控制器通过与移动交换中心进行信令交互确定本 次业务对应的移动交换中心。到 S410。 S400中的信令可以为七号信令, S400 中的移动交换中心可以为移动交换中心资源池中的移动交换中心。
在 S400中 , 基站控制器通过与移动交换中心进行信令交互确定本次业 务对应的移动交换中心的方式有多种, 一个具体的例子为: 基站控制器在 发送建链请求消息时, 即需要确定出接收建链请求消息的移动交换中心, 基站控制器可以将接收建链请求消息的移动交换中心确定为本次业务对应 的移动交换中心。 这种确定移动交换中心的方法可以很好的适用于建链请 求消息不会被接收方拒绝的情况。 上述建链请求消息为 BSC建立七号信令 链路过程中向 MSC发送的包含 Complete L3 message (完成层三信息) 的 Connect Request (建链请求, CR )消息。 另一个具体的例子为: 基站控制 器在接收到 Connect Confirm (建链确认, CC )消息时, 将发送建链确认消 息的移动交换中心确定为本次业务对应的移动交换中心。 第二个例子不仅 能够适用于建链请求消息不被接收方拒绝的应用场景, 而且, 还能够很好 的适用于建链请求消息有可能被接收方拒绝的应用场景。 本实施例中的基 站控制器也可以通过其它信令的交互来确定本次业务对应的移动交换中 心, 本实施例不限制基站控制器确定本次业务对应的移动交换中心的具体 实现方式。
S410、 基站控制器根据预设置信息或本次业务对应的移动交换中心发 送来的消息判断本次业务对应的移动交换中心是否支持宽带自适应多速 率。 到 S420。
S410 中的预设置信息可以表示出各移动交换中心是否支持宽带自适应 多速率。 例如, 预设置信息可以包括: 移动交换中心标识与是否支持宽带 自适应多速率信息的对应关系; 再例如, 预设置信息可以包括: 支持宽带 自适应多速率的移动交换中心列表和不支持宽带自适应多速率的移动交换 中心列表。 本实施例不限制预设置信息的具体表示方式。
在移动交换中心发送来的消息中携带有是否支持宽带自适应多速率信 息的情况下, 基站控制器可以在接收到移动交换中心发送来的消息时, 从 该消息携带的信息获知移动交换中心是否支持宽带自适应多速率。
是否支持宽带自适应多速率信息可以携带在移动交换中心向基站控制 器发送的现有消息的现有字段中; 移动交换中心也可以新增消息, 以携带 该是否支持宽带自适应多速率信息, 且该新增消息可以单独向基站控制器 发送, 也可以携带在移动交换中心向基站控制器发送的现有消息的新增的 独立信元中, 并向基站控制器发送该现有消息。 本实施例不限制移动交换 中心向基站控制器发送是否支持宽带自适应多速率信息的具体实现方式。
S420、 基站控制器向终端发送移动交换中心是否支持宽带自适应多速 率能力的指示信息。 该指示信息用于通知终端是否向本次业务对应的移动 交换中心上报宽带自适应多速率能力信息。 基站控制器可以通过点对点消 息向终端发送移动交换中心是否支持宽带自适应多速率能力的指示信息。 本实施例中的终端可以包括: 本次业务的主叫终端和 /或被叫终端。
基站控制器在向终端发送移动交换中心是否支持宽带自适应多速率能 力的指示信息时, 基站控制器可以利用现有点对点消息中的现有字段来发 送该指示信息, 也可以利用新增消息来发送该指示信息, 例如, 基站控制 器将新增消息 AMR-WB Notify (通知) 消息携带在基站控制器向终端发送 的现有点对点消息的新增信元中;再例如 ,基站控制器将新增消息 AMR- WB Notify消息携带在基站控制器向终端发送的现有点对点消息的原有信元中。 为方便描述, 上述新增信元和原有信元可以简称为指示信息专用信元, 同 样的, 该专用信元可以仅携带移动交换中心是否支持宽带自适应多速率能 力的指示信息, 也可以携带移动交换中心是否支持宽带自适应多速率能力 的指示信息和其它信息。
在基站控制器通过点对点消息向终端发送指示信息后, 终端判断出接 收到的指示信息表示允许上报宽带自适应多速率能力信息, 则终端向移动 交换中心上 >¾宽带自适应多速率能力信息, 如终端利用建立消息或者呼叫 确认消息等向移动交换中心上报宽带自适应多速率能力信息; 如果终端判 断出接收到的指示信息表示不允许上报宽带自适应多速率能力信息, 则终 端不会向移动交换中心上报宽带自适应多速率能力信息 , 从而避免了在移 动交换中心不支持宽带自适应多速率能力的情况下, 因终端上报宽带自适 应多速率能力信息而引起的呼叫失败现象。
另外, 如果终端不支持宽带自适应多速率能力, 则终端可能不能有效 识别点对点消息中的指示信息, 终端可以丢弃该指示信息, 如终端丢弃接 收到的 AMR-WB Notify消息。
从上述针对实施例四的描述可知 , 基站控制器通过确定本次业务对应 的移动交换中心, 并判断该移动交换中心是否支持宽带自适应多速率能力, 从而基站控制器可以在判断出移动交换中心支持宽带自适应多速率能力 时, 向终端发送允许上报宽带自适应多速率能力的指示信息, 在判断出移 动交换中心不支持宽带自适应多速率能力时, 向终端发送不允许上报宽带 自适应多速率能力的指示信息, 使终端可以根据基站控制器发送来的信息 明确获知是否需要向移动交换中心上报宽带自适应多速率能力信息 , 从而 实施例四能够避免呼叫失败现象; 另外, 由于上述指示信息是基站控制器 通过点对点消息向终端发送的, 因此, 实施例四能够避免通过 Packet SI Status消息下发 SI3时由于基站控制器不支持 Packet SI Status消息而导致的呼 叫失败现象。 由于基站控制器能够先确定出本次呼叫对应的移动交换中心, 然后, 再针对该移动交换中心通过点对点的消息通知终端, 因此, 实施例 四能够很好的适应于 MSC资源池技术。
实施例五、 能力信息上 方法。 该方法的流程如附图 5所示。
图 5中, S500、 终端接收移动交换中心或者基站控制器发送来的消息。 S500 中的消息中可以携带有移动交换中心支持宽带自适应多速率能力 的指示信息, 也可以不携带该指示信息。
在携带有移动交换中心支持宽带自适应多速率能力的指示信息的消息 为移动交换中心发送来的消息的情况下, 终端接收到的该消息可以是终端 在向移动交换中心发送 Setup消息或发送 Call Confirm消息之前接收到的消 息。 移动交换中心向终端发送携带有移动交换中心支持宽带自适应多速率 能力的指示信息的内容如上述实施例一中的记载, 在此不再重复说明。
在携带有移动交换中心支持宽带自适应多速率能力的指示信息的消息 为基站控制器发送来的消息的情况下 , 终端接收到的消息可以是基站控制 器在建立电路域业务过程中发送的层三信令, 也可以是基站控制器通过与 移动交换中心进行信令交互确定出终端的本次业务对应的移动交换中心后 向终端发送的消息。 在终端接收到的消息携带有移动交换中心支持宽带自适应多速率能力 的指示信息的情况下, 终端接收到的消息可以是移动交换中心或基站控制 器主动发送来的消息, 也可以是移动交换中心应终端发送的请求上报能力 信息而向终端发送的消息。 具体如上述实施例二和实施例四的描述, 在此 不再重复说明。
S510、 终端如果从接收到的上述消息中获取到移动交换中心支持宽带 自适应多速率能力的指示信息, 则终端向移动交换中心上报宽带自适应多 速率能力信息, 否则, 终端不向移动交换中心上 "¾宽带自适应多速率能力 信息。
该指示信息可以表示出移动交换中心是否支持宽带自适应多速率能 力, 该指示信息也可以表示出移动交换中心是否允许终端上报宽带自适应 多速率能力的指示信息。
终端在上>¾宽带自适应多速率能力信息时, 上"¾的宽带自适应多速率 能力信息可以通过终端向移动交换中心或者基站控制器发送的现有消息的 现有字段来发送, 也可以利用新增消息向移动交换中心或者基站控制器来 发送。 终端可以直接发送该新增消息, 终端也可以将新增消息作为独立的 信元携带在现有消息中发送。 具体的例子如上述各实施例的描述, 在此不 再重复说明。
从上述针对实施例五的描述可知, 终端通过在接收到指示信息后才向 移动交换中心上报宽带自适应多速率能力信息, 从而避免了呼叫失败现象。

525、 Setup消息经过 BSC传输至 MSC。
实施例九、 移动交换中心。 该移动交换中心如附图 9所示。
图 9中的移动交换中心包括: 第一指示信息发送模块 900, 可选的还可 以包括: 接收模块 910。
第一指示信息发送模块 900, 用于在移动交换中心建立业务过程中, 向 终端发送移动交换中心是否支持宽带自适应多速率能力的指示信息。 该指 示信息可以表示出其所在的移动交换中心是否支持宽带自适应多速率能 力, 也可以表示出是否允许终端向移动交换中心上报宽带自适应多速率能 力。
第一指示信息发送模块 900可以主动向终端发送指示信息。 第一指示信 息发送模块 900主动发送指示信息即: 第一指示信息发送模块 900在没有接 收到相关请求的情况下, 向终端发送指示信息。 这里的相关请求为用于请 求上报能力信息的请求, 也即用于请求上述指示信息的请求。
第一指示信息发送模块 900也可以被动的向终端发送指示信息, 即第一 指示信息发送模块 900在接收到终端发送来的请求上报能力信息后 , 根据该 请求上报能力信息向终端发送移动交换中心是否支持宽带自适应多速率能 力的指示信息。 第一指示信息发送模块 900可以在其所在的移动交换中心支 持宽带自适应多速率的情况下, 向终端发送表示允许上报宽带自适应多速 率能力的指示信息, 此时的指示信息还可以表示出移动交换中心支持宽带 自适应多速率能力。 如果第一指示信息发送模块 900所在的移动交换中心不 支持宽带自适应多速率, 则第一指示信息发送模块 900可以不向终端发送指 示信息。 当然, 在第一指示信息发送模块 900所在的移动交换中心不支持宽 带自适应多速率的情况下, 第一指示信息发送模块 900也可以向终端发送表 示不允许上报宽带自适应多速率能力的指示信息, 此时的指示信息还可以 表示出移动交换中心不支持宽带自适应多速率能力。
需要特别说明的是, 在第一指示信息发送模块 900所在的移动交换中心 不支持宽带自适应多速率的情况下, 第一指示信息发送模块 900可能不能有 效识别终端发送来的请求上报能力信息, 第一指示信息发送模块 900可以直 接丢弃接收到的请求上报能力信息。 这样, 第一指示信息发送模块 900不会 向终端发送移动交换中心是否支持宽带自适应多速率能力的指示信息。 终 端在发送了请求上报能力信息后, 如果在发送 Setup消息或发送 Call Confirm 消息时, 仍没有接收到移动交换中心发送来的指示信息, 则终端可以确定 出移动交换中心不允许上报宽带自适应多速率能力信息, 从而终端不会向 移动交换中心上报宽带自适应多速率能力信息。
不论第一指示信息发送模块 900是主动向终端发送指示信息, 还是被动 向终端发送指示信息 , 第一指示信息发送模块 900均可以在终端向移动交换 中心发送 Setup消息或发送 Call Confirm消息之前, 向终端发送指示信息。 第 一指示信息发送模块 900可以利用向终端发送的现有消息中的现有字段来 实现指示信息的发送 , 第一指示信息发送模块 900也可以利用新增的消息向 终端发送指示信息。
在利用现有消息中的现有字段向终端发送指示信息时, 一个具体的例 子为: 第一指示信息发送模块 900利用连接管理服务接受消息或者加密模式 命令中的现有字段的空闲比特来携带指示信息, 并向终端发送连接管理服 务接受消息或者加密模式命令。 在利用新增的消息向终端发送指示信息时, 第一指示信息发送模块 900 可以直接向终端发送该新增消息; 第一指示信息发送模块 900也可以将新增 消息作为独立的信元携带在移动交换中心向终端发送的其它消息中, 并向 终端发送该其它消息, 即在其它消息中增加新信元以携带该新增消息。 另 外 , 第一指示信息发送模块 900还可以将新增消息携带在移动交换中心向终 端发送的其它消息的原有信元中。 本实施例不限制第一指示信息发送模块 900向终端发送指示信息的具体实现方式。
第一指示信息发送模块 900主动向终端发送指示信息、 以及第一指示信 息发送模块 900被动向终端发送指示信息的具体例子如上述实施例一中的 描述, 在此不再重复说明。
接收模块 910, 用于接收终端根据上述指示信息上报的宽带自适应多速 率能力信息。 终端上报的宽带自适应多速率能力信息为: 终端确定出接收 到的指示信息表示移动交换中心允许上报宽带自适应多速率能力后, 向移 动交换中心上报的宽带自适应多速率能力信息。
需要说明的是, 如果终端接收到移动交换中心发送来的指示信息, 且 确定出接收到的该指示信息表示移动交换中心不允许上报宽带自适应多速 率能力信息, 则终端不会向移动交换中心上 ^艮宽带自适应多速率能力信息, 从而避免了在移动交换中心不支持宽带自适应多速率能力的情况下, 因终 端上报宽带自适应多速率能力信息而引起的呼叫失败现象。
接收模块 910接收终端上报的宽带自适应多速率能力信息的一个具体 的例子为: 接收模块 910接收终端发送来的建立消息, 并从建立消息的承载 能力信元的 SPEECH VERSION字段中获取终端上报的宽带自适应多速率能 力信息。 接收模块 910接收终端上报的宽带自适应多速率能力信息的另一个 具体的例子为: 接收模块 910接收终端发送来的建立消息或者呼叫确认消 息, 并从消息携带的新增信元中获取终端上报的宽带自适应多速率能力信 息。 本实施例不限制接收模块 910从终端发送来的消息中获取终端上报的宽 带自适应多速率能力信息的具体实现方式。
实施例十、 基站控制器。 基站控制器如图 10所示。
图 10中的基站控制器包括: 第二指示信息生成模块 1000和第二指示信 息发送模块 1010。
第二指示信息生成模块 1000, 用于在建立电路域业务过程中, 将移动 交换中心是否支持宽带自适应多速率能力的指示信息携带在层三信令中。 这里的指示信息用于通知终端是否向移动交换中心上报宽带自适应多速率 能力信息, 该指示信息可以表示出移动交换中心是否支持宽带自适应多速 率能力。
第二指示信息生成模块 1000可以通过预先设置信息等方式获知与其所 在的基站控制器连接的移动交换中心是否支持宽带自适应多速率能力。
第二指示信息生成模块 1000可以利用建立电路域业务过程中现有的层 三信令中的空闲比特位来携带上述指示信息, 第二指示信息生成模块 1000 也可以利用新增的消息来携带上述指示信息, 即第二指示信息生成模块
1000将新增的消息携带在层三信令的指示信息专用信元中。
第二指示信息生成模块 1000利用现有消息中的字段携带上述指示信息 的一个具体的例子为: 第二指示信息生成模块 1000将指示信息携带在立即 指配消息的空闲比特中。
第二指示信息生成模块 1000在利用新增的消息携带上述指示信息时, 第二指示信息生成模块 1000可以将新增的消息作为独立的信元携带在基站 控制器向终端发送的层三信令中。 该独立的信元可以称简称为指示信息专 用信元。 本实施例不限制第二指示信息生成模块 1000利用层三信令来携带 上述指示信息的具体实现方式。
第二指示信息发送模块 1010, 用于向终端发送上述层三信令。 上述指 示信息用于通知终端是否向移动交换中心上报宽带自适应多速率能力信 息。 在第二指示信息生成模块 1000利用新增的消息来携带上述指示信息 时, 第二指示信息发送模块 1010可以直接向终端发送该新增消息, 即该新 增消息为层三信令且该层三信令为新增的信令; 第二指示信息生成模块
1000也可以将新增消息作为独立的信元携带在基站控制器向终端发送的现 有层三信令中 , 第二指示信息发送模块 1010向终端发送该现有层三信令, 即第二指示信息生成模块 1000在现有层三信令中增加新信元以携带该新增 消息, 现有层三信令如立即指配消息, 第二指示信息发送模块 1010发送立 即指配消息。 另外, 第二指示信息生成模块 1000还可以将新增消息携带在 基站控制器向终端发送的现有层三信令的原有信元中, 并由第二指示信息 发送模块 1010发送该层三信令。
在第二指示信息发送模块 1010向终端发送携带有指示信息的层三信令 后, 终端判断出接收到的指示信息表示移动交换中心允许上报宽带自适应 多速率能力信息 , 则终端向移动交换中心上 ^艮宽带自适应多速率能力信息 , 终端可以利用现有消息的现有字段向移动交换中心发送宽带自适应多速率 能力信息, 终端也可以利用新增消息向移动交换中心发送; 如果终端判断 出接收到的指示信息表示移动交换中心不允许上报宽带自适应多速率能力 信息, 则终端不会向移动交换中心上报宽带自适应多速率能力信息, 从而 避免了在移动交换中心不支持宽带自适应多速率能力的情况下, 因终端上 报宽带自适应多速率能力信息而引起的呼叫失败现象。
实施例十一、 终端设备。 该终端设备如附图 11所示。
图 11中的终端设备包括: 第一生成模块 1100和第一上报模块 1110。 第一生成模块 1100 , 用于将宽带自适应多速率能力信息携带在消息的 新增信元中。
第一生成模块 1100可以在终端设备接收到基站控制器或者移动交换中 心发送来的移动交换中心是否支持宽带自适应多速率能力的指示信息, 且 根据该指示信息判断出允许上报宽带自适应多速率能力信息后, 再将宽带 自适应多速率能力信息携带在消息的新增信元中。另外,第一生成模块 1 100 也可以在基站控制器没有接收到基站控制器和移动交换中心发送来的指示 信息的情况下, 主动的将宽带自适应多速率能力信息携带在消息的新增信 元中。
上述消息中的新增信元可以仅携带宽带自适应多速率能力信息, 也可 以携带宽带自适应多速率能力信息和其它信息。 上述新增信元可以称为宽 带自适应多速率能力信息专用信元, 同样的, 本实施例中的宽带自适应多 速率能力信息专用信元并不是特指该信元中仅携带宽带自适应多速率能力 信息。
第一上 模块 1110, 用于向移动交换中心发送上述消息。
不论是第一生成模块 1100主动将宽带自适应多速率能力信息携带在消 息的新增信元中, 还是被动的根据接收到的指示信息宽带自适应多速率能 力信息携带在消息的新增信元中, 第一上 模块 1110向移动交换中心发送 的消息可以是建立消息或者呼叫确认消息等。 当然, 第一生成模块 1100也 可以利用向移动交换中心发送的其他消息携带上述新增信元, 本实施例不 限制携带上述新增信元的具体消息。
实施例十二、 基站控制器。 该基站控制器如附图 12所示。
图 12中的基站控制器包括: 确定模块 1200、 判断模块 1210和第三指 示信息发送模块 1220。
确定模块 1200, 用于通过其所在的基站控制器与移动交换中心进行信 令交换确定本次业务对应的移动交换中心。 这里的信令可以为七号信令 , 这里的移动交换中心可以为移动交换中心资源池中的移动交换中心。
在本实施例中, 确定模块 1200通过其所在的基站控制器与移动交换中 心进行信令交换确定本次业务对应的移动交换中心的方式有多种, 一个具 体的例子为: 基站控制器在发送建链请求消息时, 即需要确定出接收建链 请求消息的移动交换中心, 确定模块 1200可以将接收建链请求消息的移动 交换中心确定为本次业务对应的移动交换中心。 确定模块 1200这种确定移 动交换中心的方式可以很好的适用于建链请求消息不会被接收方拒绝的情 况。 上述建链请求消息为 BSC建立七号信令链路过程中向 MSC发送的包 含 Complete L3 message (完成层三信息 ) 的 Connect Request (建链请求, CR )消息。另一个具体的例子为:基站控制器在接收到 Connect Confirm (建 链确认, CC )消息时, 确定模块 1200将发送建链确认消息的移动交换中心 确定为本次业务对应的移动交换中心。 第二个例子不仅能够适用于建链请 求消息不被接收方拒绝的应用场景, 而且, 还能够很好的适用于建链请求 消息有可能被接收方拒绝的应用场景。 本实施例中的确定模块 1200也可以 通过其它信令的传输来确定本次业务对应的移动交换中心, 本实施例不限 制确定模块 1200确定本次业务对应的移动交换中心的具体实现方式。
判断模块 1210, 用于根据预设置信息或移动交换中心发送来的消息判 断该移动交换中心是否支持宽带自适应多速率。
这里的预设置信息可以表示出各移动交换中心是否支持宽带自适应多 速率。 例如, 预设置信息可以包括: 移动交换中心标识与是否支持宽带自 适应多速率信息的对应关系; 再例如, 预设置信息可以包括: 支持宽带自 适应多速率的移动交换中心列表和不支持宽带自适应多速率的移动交换中 心列表。 本实施例不限制预设置信息的具体表示方式。
在移动交换中心发送来的消息中携带有是否支持宽带自适应多速率信 息的情况下, 判断模块 1210可以在基站控制器接收到移动交换中心发送来 的消息时, 从该消息携带的信息获知移动交换中心是否支持宽带自适应多 速率。
第三指示信息发送模块 1220,用于根据判断模块 1210的判断结果向该 业务的主叫终端和 /或被叫终端发送移动交换中心是否支持宽带自适应多速 率能力的指示信息。 这里的指示信息用于通知终端是否向移动交换中心上 报宽带自适应多速率能力信息。 第三指示信息发送模块 1220可以通过点对 点消息向终端发送移动交换中心是否支持宽带自适应多速率能力的指示信 息。 本实施例中的终端可以包括: 本次业务的主叫终端和 /或被叫终端。
第三指示信息发送模块 1220在向终端发送移动交换中心是否支持宽带 自适应多速率能力的指示信息时, 第三指示信息发送模块 1220可以利用现 有点对点消息中的现有字段来发送该指示信息, 也可以利用新增消息来发 送该指示信息, 例如, 第三指示信息发送模块 1220将新增消息 AMR-WB Notify (通知)消息携带在基站控制器向终端发送的现有点对点消息的新增 信元中,并发送;再例如,第三指示信息发送模块 1220将新增消息 AMR-WB Notify消息携带在基站控制器向终端发送的现有点对点消息的原有信元中, 并发送。
在第三指示信息发送模块 1220通过点对点消息向终端发送指示信息 后, 终端判断出接收到的指示信息表示允许上报宽带自适应多速率能力信 息, 则终端向移动交换中心上报宽带自适应多速率能力信息, 如终端利用 建立消息或者呼叫确认消息等向移动交换中心上报宽带自适应多速率能力 信息; 如果终端判断出接收到的指示信息表示不允许上报宽带自适应多速 率能力信息, 则终端不会向移动交换中心上 ^艮宽带自适应多速率能力信息, 从而避免了在移动交换中心不支持宽带自适应多速率能力的情况下, 因终 端上报宽带自适应多速率能力信息而引起的呼叫失败现象。
另外, 如果终端不支持宽带自适应多速率能力, 则终端可能不能有效 识别点对点消息中的指示信息, 终端可以丢弃该指示信息, 如终端丢弃接 收到的 AMR-WB Notify消息。
实施例十三、 终端设备。 该终端设备如附图 13所示。
图 13中的终端设备包括: 接收模块 1300和第二上报模块 1310。
接收模块 1300,用于接收移动交换中心或者基站控制器发送来的消息。 接收模块 1300接收到的消息中可以携带有移动交换中心支持宽带自适 应多速率能力的指示信息, 也可以不携带该指示信息。 在接收模块 1300接收到的携带有移动交换中心支持宽带自适应多速率 能力的指示信息的消息为移动交换中心发送来的消息的情况下, 接收模块 1300接收到的该消息可以是终端设备在向移动交换中心发送 Setup消息或 发送 Call Confirm消息之前接收到的消息。移动交换中心向终端设备发送携 带有移动交换中心支持宽带自适应多速率能力的指示信息的内容如上述实 施例一中的记载, 在此不再重复说明。
在接收模块 1300接收到的携带有移动交换中心支持宽带自适应多速率 能力的指示信息的消息为基站控制器发送来的消息的情况下, 接收模块 1300接收到的消息可以是基站控制器在建立电路域业务过程中发送的层三 信令, 也可以是基站控制器通过与移动交换中心进行信令交互确定出终端 的本次业务对应的移动交换中心后向终端设备发送的消息。
在接收模块 1300接收到的消息携带有移动交换中心支持宽带自适应多 速率能力的指示信息的情况下, 接收模块 1300接收到的消息可以是移动交 换中心或基站控制器主动发送来的消息, 也可以是移动交换中心应终端设 备发送的请求上报能力信息而向终端发送的消息。 具体如上述实施例二和 实施例四的描述, 在此不再重复说明。
第二上报模块 1310, 用于如果从接收模块 1300接收到的消息中获取到 移动交换中心支持宽带自适应多速率能力的指示信息, 则向移动交换中心 上报宽带自适应多速率能力信息, 否则, 不向移动交换中心上报宽带自适 应多速率能力信息。 该指示信息可以表示出移动交换中心是否支持宽带自 适应多速率能力, 该指示信息也可以表示出移动交换中心是否允许终端上 报宽带自适应多速率能力的指示信息。
第二上报模块 1310在上报宽带自适应多速率能力信息时, 上报的宽带 自适应多速率能力信息可以通过终端设备向移动交换中心或者向基站控制 器发送的现有消息的现有字段来发送, 也可以利用新增消息向移动交换中 心或者向基站控制器来发送。 第二上报模块 1310可以直接发送该新增消息 , 第二上报模块 1310也可以将新增消息作为独立的信元携带在现有消息中发 送。 具体的例子如上述各实施例的描述, 在此不再重复说明。
在上述实施例一至实施例十三中都涉及到 MS向 ^«(上"¾宽带自适应 多速率能力信息, MS可以利用现有的方法向 MSC上报宽带自适应多速率能 力信息 , 如 MS利用向 MSC发送的 Setup消息或者 Call Confirm消息中的 Bear Capability IE中的 Speech Veersion字段来上报宽带自适应多速率能力信息。 MS也可以利用在新增消息的方式向 MSC上报宽带自适应多速率能力信息, 如 MS不使用 Setup消息和 Call Confirm消息中的 Bear Capability IE上报宽带 自适应多速率能力信息, 而是将 AMR-WB能力信息做为向 MSC发送的 Setup 或 Call Confirm消息中的一个新增信元。 该新增信元可以继承原有的 Bearer Capability IE的结构, 也可以与 Bearer Capability IE的结构不同, 如将 Speech Version字段作为一个单独的 IE等。
终端利用 Setup消息上报宽带自适应多速率能力信息时, Setup消息的一 个具体结构的例子如表 1所示。
表 1
Figure imgf000034_0001
Figure imgf000035_0001
表 1中 , AMR-WB Capability信元为新增信元, 用于携带 MS向 MSC上报 的宽带自适应多速率能力信息, 这个 AMR-WB Capability信元的 IEI (信元 标识)可以预先由网络分配, AMR-WB Capability信元可以采用原 Speech Version的描述方式, 也可以采用 Bearer capability IE的描述方式, 当然, 也 可以采用其它描述方式。 AMR-WB Capability信元描述方式的一个具体的例 子如表 2所示。
表 2 8 7 6 5 4 3 2 1
