| 技术特征描述以及公开性判断结果 | 对比文件原文引用 | 公开性论述 |
| 技术特征A《直接公开》 | [0025] “The SIP UE should be able to have both IP connectivity (PS domain) and voice connectivity (CS domain) simultaneously... act upon the (SIP) information in order to establish circuit switched connection via CS domain whenever so required.” | 对比文件明确公开了用户设备（UE）配置为同时执行电路交换（CS）会话（语音连接）并根据会话控制协议（SIP）发送和接收消息（IP连接），与特征A实质相同。 |
| 技术特征B《直接公开》 | [0092] “the MGCF 40 sends a SIP INVITE request to the conference server 20. The INVITE request contains a local descriptor of the media resource. Furthermore, the MGCF 40 converts the E.164 number to a Telephone Uniform Resource Locator (Tel URL), which corresponds to the conference-URI that identifies the focus 24 in the conference server 20.” <br> [0142]-[0143] “the MGCF will eventually establish a new SIP session attempt towards the S-CSCF_A addressed by the routing number... The S-CSCF_A which receives the SIP session establishment, i.e. INVITE method, from the MGCF may be the same that is controlling the (main) SIP session... After the S-CSCF_A has received the INVITE from the MGCF, it will resolve based on the used routing number... the original SIP session.” | 对比文件中的网络控制节点（会议服务器/S-CSCF）接收特定的会话控制消息（INVITE）。该消息包含用于建立特定分组交换连接的信息（Tel URL/E.164路由号码）。该分组交换连接（会议SIP对话/新SIP对话）能够支持对网络节点的特定分组服务（IMS会议/语音服务）。该信息以适合于会话控制协议的格式编码（SIP中的Tel URL/p-header/SDP）。 |
| 技术特征C《直接公开》 | [0092] “In step 6, the conference server 20 reserves the media resources from the conference media mixer in the MGW 50... The descriptor of the reserved media resources is then sent back to the MGCF 40 in a SIP 200 response.” <br> [0143] “After the S-CSCF_A has received the INVITE from the MGCF, it will resolve based on the used routing number... the original SIP session.” | 对比文件中的控制器（会议服务器/S-CSCF）从特定会话控制消息中获取信息（Tel URL/路由号码），并基于所获取的信息建立特定分组交换连接（预留媒体资源建立会议会话，或解析路由号码绑定新SIP对话）。 |
| 技术特征D《直接公开》 | [0143] “After the S-CSCF_A has received the INVITE from the MGCF, it will resolve based on the used routing number... the original SIP session.” <br> [0107] “The CS bearer and the SIP dialog are tied together in the conference server 20 which is adapted to handle and synchronize actually two SIP dialogs that both are related to the CS session of the host terminal MS-A 15. A dynamic routing number pool and allocation can be arranged.” | 对比文件明确公开了使用路由号码/会话标识符将分组交换连接（SIP对话/会议会话）绑定至电路交换会话（CS承载），与特征D实质相同。 |
| 技术特征E《直接公开》 | [0002] “In IMS, the Session Initiation Protocol (SIP) is used as the main session control protocol...” | 对比文件明确指定SIP为IMS中的会话控制协议，与特征E相同。 |
| 技术特征F 未公开 | [0118] “The state is XML-coded inside a SIP NOTIFY message.” <br> [0106] “SIP/SDP (Session Description Protocol) extension are used to carry CS specific information...” | 对比文件使用XML、SDP扩展或p-header承载信息，未使用或暗示message/sipfrag类型。 |
| 技术特征G 未公开 | [0118] “The state is XML-coded inside a SIP NOTIFY message.” <br> [0106] “SIP/SDP extension are used to carry CS specific information... The conference routing or phone number is then carried in the response.” | 对比文件承载的是状态数据或参数，并非完整的会话控制消息（如SIP响应/请求）嵌入在另一类型的消息中，未公开或隐含公开此特征。 |
| 技术特征H《直接公开》 | [0092] “the MGCF 40 sends a SIP INVITE request to the conference server 20.” <br> [0138] “An INVITE method which establishes SIP dialog between IMS subscriber A and B is sent in step 1 by IMS subscriber A's UE 15.” | 对比文件明确公开了特定的会话控制消息为邀请消息（INVITE），与特征H相同。 |
| 技术特征I《直接公开》 | [0118] “the conference server always sends a NOTIFY message to the subscribed mobile terminal MS-A 15 when the state of the conference changes.” | 对比文件明确公开了特定的会话控制消息为通告消息（NOTIFY），与特征I相同。 |
| 技术特征J《直接公开》 | [0118] “For subscription, the mobile terminal MS-A 15 may subscribe the state of the conference session. A SIP SUBSCRIBE request is sent... the conference server always sends a NOTIFY message...” | 对比文件明确公开了控制器（UE）订购（SUBSCRIBE）所述通告消息（NOTIFY），与特征J相同。 |
| 技术特征K 未公开 | [0133] “The registration procedure is modified... During the registration procedure, the IMS subscriber A's UE 15 had possibly issued a REGISTER method...” <br> [0118] “For subscription, the mobile terminal MS-A 15 may subscribe the state of the conference session...” | 对比文件未提及互联网多媒体系统集中式服务（ICS）。订阅发生在会议建立过程中，并非在到ICS的注册之后立即执行，未公开或隐含公开此特征。 |
| 技术特征L《直接公开》 | [0027] “The SIP session may then remain active during the circuit-switched call.” <br> [0118] “the conference server always sends a NOTIFY message to the subscribed mobile terminal MS-A 15 when the state of the conference changes.” | 对比文件公开了在建立分组交换连接（SIP对话）后，通过该连接向网络节点/用户设备发送和接收会话控制消息（如NOTIFY），与特征L相同。 |
| 技术特征M《直接公开》 | [0019] “A terminal device for providing a connection to an IP-based network via a circuit-switched network, said terminal device comprising: communicating means for receiving a temporary routing number delivered to said user terminal; and establishing means for establishing a circuit-switched call leg from said user terminal to said IP-based network using said routing number.” <br> [0022] “A server device for providing a connection from an IP-based network to a circuit-switched network, said server device comprising communicating means for receiving from said circuit-switched network a connection request via a data path and for delivering via said data path a temporary routing number for said circuit-switched network.” | 对比文件明确公开了设备可以是用户设备（终端装置），网络节点是被配置为在CS接入网络上提供分组交换服务（IMS服务）的网络控制节点（服务器装置），与特征M相同。 |
| 技术特征N《直接公开》 | [0022] “A server device for providing a connection from an IP-based network to a circuit-switched network...” <br> [0019] “A terminal device for providing a connection to an IP-based network via a circuit-switched network...” | 对比文件明确公开了设备可以是网络控制节点（服务器装置），网络节点是用户设备（终端装置），与特征N相同。 |
