## 特征比对表格

技术特征描述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**:所述方法包括:在多模式便携式用户终端与服务的无线局域网之间建立链路。<br>**《直接公开》**[0022] “A wireless unit can also be called a subscriber station, subscriber unit, mobile station, mobile, remote station, remote terminal, access terminal, **user terminal**, user agent, or user equipment.”<br>[0013] “In an embodiment, a system is designed to provide nomadic cellular services including voice over **I.E.E.E. 802.11**.”<br>[0024] “The OCS is responsible of translating between SIP and IOS protocols. It functions as a SIP Server for the **wireless unit** and as a CDMA BSC for the MSC.”<br>[0067] “An inter-AP handoff trigger is generated when the link quality of the **current AP** degrades, and there is reason to believe that moving to a different AP improves performance. The communication link comprises the **wireless terminal-AP link**, and the AP-OCS link.”对比文件明确公开了一个无线终端(user terminal/wireless terminal)在IEEE 802.11 WLAN环境中操作。该终端与WLAN接入点(AP)之间存在无线链路(wireless terminal-AP link),该链路用于承载蜂窝语音等服务。因此,本领域技术人员能够毫无疑义地得出对比文件公开了在用户终端与服务的WLAN之间建立链路的技术特征。
**技术特征B**:经由所述建立的无线局域网链路建立呼叫。<br>**《直接公开》**[0015] “Key cellular features supported include, but are not limited to: **Voice services** using Enhanced Variable Rate Codec (EVRC) (MO and MT)”<br>[0013] “In an embodiment, a system is designed to provide nomadic cellular services including **voice over I.E.E.E. 802.11**.”<br>[0032] “The wireless terminal exchanges **voice packets** with the MGW using the EVRS/RTP/UDP/IP protocol…”对比文件明确其系统设计用于通过IEEE 802.11网络提供语音服务(voice over 802.11),并描述了无线终端通过WLAN链路交换语音分组。这直接对应于经由WLAN链路建立(语音)呼叫。因此,该技术特征被对比文件直接公开。
**技术特征C**:监视服务的蜂窝电话网络。<br>**《直接公开》**[00188] “During a voice call in **802.11 operation mode**, the **wireless terminal should monitor both networks (802.11, CDMA)**.”<br>[00194] “During an 802.11 call, the user terminal should periodically monitor both the 802.11 and the **CDMA networks**, using the separated hardware.”对比文件多次明确指出,当无线终端在802.11模式(即WLAN模式)下进行语音呼叫时,它应同时监视(monitor)802.11和CDMA网络。这直接公开了在WLAN呼叫期间“监视服务的蜂窝电话网络”这一技术特征。
**技术特征D**:将在所述服务的蜂窝电话网络内识别所述用户终端的信息转发给所述服务的无线局域网。<br>**《隐含公开》**[0037] “Primarily the cellular subscription will be used to manage services. This implies that the **cellular ESN and MSI along with AKEY** will be used.”<br>[0038] “An Obiwan capable terminal, when operating in the WLAN environment, will use SIP for call processing signaling. **It will tunnel the cellular subscription using SIP signaling infrastructure.**”<br>[0039] “The OCS will store the mapping between the internet address (TCP/IP address and port or UDP/IP address and port) and **the cellular subscription** in persistent redundant storage.”对比文件公开了无线终端使用蜂窝订阅信息(如ESN、IMSI)进行服务管理,并在WLAN环境中通过SIP信令基础设施“隧道传输”(tunnel)该蜂窝订阅信息。隧道传输意味着将蜂窝身份信息封装在WLAN网络使用的协议(如SIP)中发送。虽然未明确说明“转发给服务的无线局域网”,但为了在WLAN环境下提供蜂窝服务,终端必须向网络侧(包括OCS)提供其蜂窝身份以进行认证和路由,而这一过程必然通过其连接的WLAN AP(即服务的WLAN)进行。因此,本领域技术人员通过合理推理可以得出,终端需要将其蜂窝身份信息通过WLAN链路转发出去,即隐含公开了该技术特征。
**技术特征E**:响应于蜂窝服务器控制器检测到所述服务的无线局域网丢失与所述用户终端的链路,接收由蜂窝服务器控制器发起的硬越区切换命令。<br>**《未公开》**[00199] “In step 501, the **wireless terminal has detected that the receive power of the 802.11 system falls below a predefined threshold**. As a result, the wireless terminal sends a power measurement report signaling message to the OCS, tunneled over the 802.11 network.”<br>[00200] “In step 502, based on a **wireless terminal report** that it has crossed a network specified threshold for signal strength, the OCS recommends a hard handoff to a CDMA network.”对比文件描述的硬越区切换触发机制是由**无线终端**检测WLAN链路质量(如接收功率低于阈值)并主动向OCS发送测量报告,OCS基于此报告发起切换。目标专利特征E强调的是由**蜂窝服务器控制器(CSC/OCS)主动检测**到WLAN链路丢失,然后发起命令。对比文件未公开OCS主动检测WLAN链路丢失的步骤,其切换触发源于终端的报告。因此,该技术特征未被对比文件公开。
**技术特征F**:基于接收到所述硬越区切换命令,执行到所述服务的蜂窝电话网络的硬越区切换。<br>**《直接公开》**[00205] “In step 506, the MSC ... sends a Handoff Command to the OCS...”<br>[00205] “In step 507, the OCS sends the **Universal Handoff Direction Message (UHDM)** to the wireless terminal ... These messages are tunneled over the 802.11 network.”<br>[00208] “In step 510, the wireless terminal tunes to CDMA mode and kick start its protocol stack to Active call state. The wireless terminal then tunes to its allocated traffic channel...”对比文件明确描述了无线终端通过WLAN接收到OCS发送的通用越区切换方向消息(UHDM,即一种硬越区切换命令),然后执行动作:调谐到CDMA模式、启动协议栈并调谐到分配的业务信道。这直接对应于“基于接收到硬越区切换命令,执行到蜂窝网络的硬越区切换”。
**技术特征G**:其中执行所述硬越区切换进一步包括:在公共控制信道消息中接收蜂窝网络资源分配。<br>**《未公开》**[00205] “In step 507, the OCS sends the Universal Handoff Direction Message to the wireless terminal ... These messages are **tunneled over the 802.11 network**.”对比文件中,包含资源分配的UHDM是通过WLAN网络(802.11)隧道传输给终端的,而不是通过蜂窝网络的**公共控制信道**(如寻呼信道)发送的。目标专利明确限定在“公共控制信道消息”中接收分配。因此,该具体限定技术特征未被对比文件公开。
**技术特征H**:响应于所述公共控制信道消息,而调谐到所述蜂窝网络中的所分配的业务信道。<br>**《未公开》**[00208] “In step 510, the wireless terminal tunes to CDMA mode and kick start its protocol stack to Active call state. The wireless terminal then tunes to its allocated traffic channel...”对比文件公开了终端调谐到分配的业务信道,但如前所述(特征G),其触发消息(UHDM)并非通过蜂窝公共控制信道接收。因此,该特征中“响应于所述公共控制信道消息”这一具体限定未被公开。
**技术特征I**:响应于与服务的基站收发器建立业务信道连接,而向所述服务的基站收发器发送越区切换完成消息。<br>**《直接公开》**[00209] “In step 511, the wireless terminal sends a **Handoff Completion Message** to the target BSS.”<br>[00211] “In step 513, the target BSS sends a Handoff Complete message to the MSC to notify it that the wireless terminal has successfully completed the hard handoff.”对比文件明确描述了无线终端在调谐到CDMA模式并建立连接后,向目标基站子系统(BSS,包含BTS)发送“越区切换完成消息”(Handoff Completion Message)。这直接对应于目标专利的特征I。
**技术特征J**:经由所述服务的蜂窝电话网络继续所述呼叫。<br>**《直接公开》**[00213] “... the wireless terminal has successfully completed the hard handoff.”<br>结合[00188] “After the handoff procedure is completed, the user terminal employs a native IS-2000 IxRTT signaling protocol stack in the signaling plain, as well as a native IS-2000 IxRTT voice processing at the traffic plain.”对比文件描述了完整的从WLAN到CDMA的硬越区切换流程,并在切换完成后,终端使用原生的CDMA(IxRTT)协议栈进行信令和语音处理。这意味着呼叫在切换后通过蜂窝网络(CDMA)继续。本领域技术人员能够毫无疑义地得出此结论。
**技术特征K**:其中在所述用户终端与所述服务的无线局域网之间建立所述呼叫包含:以从包括分组数据、因特网语音协议和视频电话的群组中选出的格式建立呼叫。<br>**《直接公开》**[0013] “... including **voice over I.E.E.E. 802.11**.”<br>[0032] “The wireless terminal exchanges voice packets with the MGW using the EVRS/**RTP**/UDP/IP protocol...”对比文件明确说明通过802.11网络提供语音服务(voice over 802.11),并描述了使用RTP/UDP/IP协议栈传输语音分组,这属于“因特网语音协议(VoIP)”的范畴。因此,对比文件直接公开了以VoIP格式建立呼叫,该格式属于权利要求K所述群组中的一种。
**技术特征L**:其中在所述用户终端与所述服务的无线局域网之间建立所述呼叫包含:与从包括IEEE 808.11、蓝牙和IEEE 802.15网络的群组中选出的无线局域网建立所述呼叫。<br>**《未公开》**全文多处提及“802.11”或“WLAN”,例如[0013]。未提及“蓝牙(Bluetooth)”或“IEEE 802.15”。对比文件仅公开了与IEEE 802.11网络建立连接和呼叫。对于权利要求L中限定的“蓝牙”和“IEEE 802.15”网络类型,对比文件没有提及。因此,该技术特征未被公开。
**技术特征M**:其中执行到所述蜂窝网络的所述硬越区切换包含:将所述呼叫交给从包括码分多址、全球移动通信系统和通用移动电信系统的群组中选出的蜂窝网络。<br>**《直接公开》**[0013] “... seamless call hand-off between the 802.11 and a **CDMA IxRTT network**, for example.”<br>[00188] “After the handoff procedure is completed, the user terminal employs a native **IS-2000 IxRTT** signaling protocol stack...”对比文件具体、明确地描述了从802.11 WLAN到CDMA网络(具体为IxRTT)的硬越区切换。CDMA(码分多址)属于权利要求M所述群组中的一种。因此,该技术特征被直接公开。
**技术特征N**:其中同时监视服务的蜂窝网络包含:监视所述蜂窝网络中的所述服务的基站收发器;并且中转发在所述蜂窝网络内识别所述用户终端的信息包含:转发从包括用户终端电子序列号、移动设备标识符、国际移动订户身份和移动身份号码的群组中选出的信息。<br>**《隐含公开》****监视BTS部分**:[00194] “The wireless terminal should maintain a list of the 4 strongest **Pilot channels** received and their associated PN offset, receive power and **BASE_ID**.” (Pilot信道由BTS发射)<br>**转发身份信息部分**:[0037] “... the **cellular ESN and MSI** along with AKEY will be used.” [0038] “It will tunnel the **cellular subscription** using SIP signaling infrastructure.”1. **监视BTS**:对比文件要求终端维护接收到的多个最强导频信道列表,导频信道由蜂窝基站(BTS)发射,监视导频信道即意味着监视发射该信道的BTS。这隐含公开了“监视服务的基站收发器”。<br>2. **转发身份信息**:对比文件明确终端使用ESN和IMSI(MSI的一种)作为蜂窝订阅信息,并通过SIP隧道传输该订阅信息。ESN和IMSI均属于权利要求N所述群组中的信息。虽然未明确描述“转发给服务的无线局域网”这一动作,但结合特征D的推理,隧道传输订阅信息必然包含转发身份信息的过程。因此,该技术特征被隐含公开。
**技术特征O**:其中监视所述蜂窝网络中的所述服务的基站收发器包含:在从包括小区和登记区(小区群组)的群组中选出的蜂窝网络区域内定位所述用户终端。<br>**《隐含公开》**[00194] “The wireless terminal should maintain a list of the 4 strongest Pilot channels received and their associated PN offset, receive power and **BASE_ID**.”<br>[00195] “The wireless terminal should therefore acquire the Paging channel of the target cell and obtain the **BASE_ID** from the System Parameters message.”BASE_ID用于识别特定的基站或小区。无线终端获取并报告BASE_ID,意味着网络侧(如OCS)可以据此知道终端当前位于哪个蜂窝小区(Cell)内。这隐含了在蜂窝网络区域(具体为“小区”)内定位用户终端。因此,该技术特征被隐含公开。
**技术特征P**:其中在所述公共控制信道消息中接收蜂窝网络资源分配包含:接收从包括寻呼消息、短消息服务消息和多播短消息服务消息的群组中选出的公共控制信道消息。<br>**《未公开》**[00205] “In step 507, the OCS sends the Universal Handoff Direction Message to the wireless terminal ... These messages are **tunneled over the 802.11 network**.”如特征G所述,对比文件中携带资源分配的UHDM是通过WLAN隧道传输的,并未提及通过蜂窝网络的“寻呼消息、SMS消息或多播SMS消息”这些特定类型的公共控制信道消息来发送。因此,该具体限定技术特征未被公开。
**技术特征Q**:其进一步包括:在监视所述服务的蜂窝网络之前,在所述蜂窝网络中登记所述用户终端。<br>**《未公开》**对比文件描述了终端在WLAN环境中使用蜂窝订阅信息,并提及OCS存储互联网地址与蜂窝订阅的映射[0039]。但未明确描述一个在“监视蜂窝网络之前”发生的、独立的、向蜂窝网络进行“登记”的步骤。终端在WLAN模式下可能通过OCS以某种方式向蜂窝网络注册其位置,但具体步骤和时机未明确。因此,该技术特征未被公开。
