技术特征描述及公开性判断对比文件原文引用公开性论述
**技术特征A**:《隐含公开》<br>包括:由在所述UE处的边缘启用器客户端EEC生成在所述UE上操作的应用客户端的性能配置文件[0027] "Server 106A calculates CSQI of various application client(s) in accordance with the detected and received channel parameters (e.g., latency, packet loss, jitter, bandwidth, etc.)"<br><br>[0030] "The received CSQI's allow an application client to display visual indication(s) of network conditions of the client device (self) and other client devices"<br><br>[0041] "client device 102A may transmit a PW message to server 106A, and a CSQI flag within the PW message may be marked as 'on'"对比文件公开了服务器基于通道参数为应用客户端计算CSQI,并且应用客户端可以显示网络状况信息。虽然对比文件没有明确使用"性能配置文件"的术语,但服务器根据通道参数计算CSQI并将其发送给客户端的过程,实际上涉及对应用客户端网络性能状态的记录和管理。结合[0041]中CSQI标志和PW消息的机制,可以隐含地认为存在对应用客户端性能状态的配置管理。
**技术特征B**:《隐含公开》<br>由所述EEC基于所述UE的性能的经验数据修改所述性能配置文件[0027] "Server 106A may determine CSQI's based on algorithms taking into account channel parameters directly measured by the server and/or channel parameter reports (e.g., RTCP SR/RR/XR) received from client devices 102"<br><br>[0031] "When connection quality becomes poor (e.g., falls below a configurable threshold), the service may switch to a lower bitrate codec. As another example, when connection quality improves (e.g., increases above a configurable threshold), the service may switch to a higher bitrate codec."对比文件公开了服务器基于通道参数(包括直接测量参数和客户端报告的参数)计算CSQI,并可根据质量变化(质量变差或变好)动态调整编解码器和比特率。这种基于实际测量数据(经验数据)进行适应性调整的过程,可以隐含地认为是基于经验数据修改性能配置的行为。
**技术特征C**:《直接公开》<br>经由无线网络向边缘数据网络发送对所述应用客户端的一个或多个性能指示符的调整的指示,对所述一个或多个性能指示符的所述调整至少部分地基于所述应用客户端的UE修改的性能配置文件[0031] "Depending on the CSQI value range (e.g., excellent, good, poor, bad, etc.), the application client and/or server 106A may perform predetermined remedial actions. For example, when connection quality becomes poor (e.g., falls below a configurable threshold), the service may switch to a lower bitrate codec."<br><br>[0029] "Server 106A may then transmit the CSQI's to respective client devices 102A and 102B."对比文件直接公开了服务器可以根据CSQI值范围执行预设的补救措施,例如当连接质量变差时切换到较低比特率编解码器。服务器向客户端发送CSQI并执行相应的调整操作,这实质上就是向客户端发送性能指示符调整指示的过程。调整至少部分基于CSQI(性能配置文件的应用)。
**技术特征D**:《直接公开》<br>和根据一个或多个调整的性能指示符,经由所述无线网络与所述边缘数据网络传送应用数据业务,以向所述应用客户端提供边缘服务[0031] "When connection quality becomes poor (e.g., falls below a configurable threshold), the service may switch to a lower bitrate codec. As another example, when connection quality improves (e.g., increases above a configurable threshold), the service may switch to a higher bitrate codec."<br><br>[0003] "Push-to-Talk (PTT) platforms involve providing PTT functionality...through clients on client devices."对比文件直接公开了基于CSQI(性能指示符)进行编解码器和比特率的调整,并据此传送音频数据业务。PTT平台本身就是通过客户端设备提供功能的通信平台,这与目标专利中"向应用客户端提供边缘服务"的描述实质相同。
**技术特征E**:《隐含公开》<br>还包括:经由所述无线网络从所述边缘数据网络接收对所述应用客户端的所述一个或多个性能指示符的指示[0029] "Server 106A may then transmit the CSQI's to respective client devices 102A and 102B."<br><br>[0030] "The received CSQI's allow an application client to display visual indication(s) of network conditions"对比文件公开了服务器向客户端设备发送CSQI,客户端接收CSQI。虽然对比文件主要描述服务器发送CSQI给客户端,但结合[0030]中客户端显示网络状况指示的功能,可以隐含地认为客户端从网络侧接收性能指示符的指示。
**技术特征F**:《隐含公开》<br>还包括:接收指示对所述应用客户端的边缘服务支持的边缘服务支持消息[0034] "In an embodiment, the CSQI trigger event includes a user launching the PTT application, a user bringing a PTT application to the foreground of the client device, a user moving to a contact list tab in the PTT application, a user selecting a contact from the contact list, client device 102A receiving a predictive wakeup message from the server, combinations thereof, or the like."<br><br>[0041] "client device 102A may transmit a PW message to server 106A, and a CSQI flag within the PW message may be marked as 'on'"对比文件公开了客户端接收预测唤醒消息等触发事件消息。虽然这些消息不是直接命名为"边缘服务支持消息",但CSQI触发和PW机制暗示了服务端对客户端功能的支持,可以隐含地认为是边缘服务支持的指示。
**技术特征G**:《直接公开》<br>其中,发送所述调整的所述指示包括:至少部分地基于所述边缘服务支持消息,发送所述调整的所述指示[0034] "In response to the CSQI trigger event, the application client may transmit a request for a first CSQI of the first client device to a server... In response to the CSQI trigger, server 106A may transmit an acknowledgment (ACK) and beginning audio quality tests with client device 102A"<br><br>[0031] "the application client and/or server 106A may perform predetermined remedial actions"对比文件直接公开了客户端在接收到CSQI触发事件后发送CSQI请求,服务器响应并进行音频质量测试,然后执行补救措施(如调整编解码器)。这个过程就是基于触发/支持消息来发送性能指示符调整指示的过程。
**技术特征H**:《直接公开》<br>还包括:至少基于对所述应用客户端的所述UE修改的性能配置文件的更新,发送对所述应用客户端的所述一个或多个性能指示符的第二调整的指示[0031] "When connection quality becomes poor (e.g., falls below a configurable threshold), the service may switch to a lower bitrate codec. As another example, when connection quality improves (e.g., increases above a configurable threshold), the service may switch to a higher bitrate codec."<br><br>[0048] "During the PTT call session, server 106A may perform periodic connection quality tests with participants...An interval between connection quality tests may be configured by the server."对比文件直接公开了服务器周期性地执行连接质量测试,并根据质量变化动态调整编解码器和比特率。这种周期性的测试和调整就是基于性能配置文件的更新进行多次(第二、第三等)调整指示发送的过程。
**技术特征I**:《隐含公开》<br>还包括:至少部分地基于所述UE修改的性能配置文件,向所述无线网络的网络设备发送对无线电资源性能指示符的调整的指示,其中,所述应用数据业务根据调整的无线电资源性能指示符经由所述无线网络的所述网络设备被传送[0017] "A server may adapt to call quality variation by adjusting one or more parameters, such as codec and/or bit-rate in response to changes to CSQI during the call, which advantageously optimizes (or at least improves) user experience."<br><br>[0031] "the application client and/or server 106A may perform predetermined remedial actions"对比文件隐含公开了服务器可以根据CSQI变化调整编解码器和比特率等参数。虽然没有明确提及向网络设备发送无线电资源调整指示,但编解码器和比特率的调整必然会涉及无线网络资源的使用调整。
**技术特征J**:《直接公开》<br>其中,发送所述调整的所述指示包括:发送第一调整的性能因子的指示,以指示所述应用数据业务的处理将由所述UE执行、将由所述边缘数据网络执行、或将在所述UE和所述边缘数据网络之间分割[0050] "When server 106A detects change(s) in CSQI's for one or more participants (e.g., client devices) of the call session (block 602), server 106A may adapt codecs and/or bit-rates based on the detected change and improve quality of service."<br><br>[0031] "Codec adaptation can be either application client or server initiated based on system configuration."对比文件直接公开了编解码器/比特率自适应可以由应用客户端或服务器发起。PTT通话会话中,音频数据的处理可以由客户端或服务器执行,这实质上就是数据处理在UE和服务器之间分配的实现。
**技术特征K**:《直接公开》<br>还包括:监测所述应用客户端的执行,以生成所述经验数据[0026] "Each of the packets may include a transmission time stamp indicating a transmission time of a respective packet as well as a sequence number identifying a position of the respective packet within the packet sequence. A recipient of the packet sequence (e.g., a client device or the server) may use the transmission time stamps and sequence numbers of the packets to estimate end-to-end latency, packet loss parameters of a channel between the client device and the server."<br><br>[0027] "Server 106A may determine CSQI's based on algorithms taking into account channel parameters directly measured by the server and/or channel parameter reports (e.g., RTCP SR/RR/XR) received from client devices 102."对比文件直接公开了通过数据包的传输时间戳和序列号监测网络通道质量(延迟、丢包等),以及客户端设备向服务器发送RTCP报告(包含通道参数)。这些过程就是监测应用客户端执行以生成经验数据的实现。
**技术特征L**:《隐含公开》<br>其中,所述UE修改的性能配置文件指示,对于所述应用客户端,至少部分地基于可用网络服务质量性能参数、当前无线电链路质量参数、UE热参数、UE处理器负载参数、UE存储可用性参数、UE存储器可用性参数、边缘资源可用性参数、应用数据时间敏感性参数、预测变化参数、预测服务质量变化参数、预测用户行为参数、安全参数、隐私参数或其任意组合,对所述一个或多个性能指示符的调整[0032] "This information (e.g., correlating channel parameters and/or CSQI with CellID and/or time of day) may then be used to perform heuristic algorithms to predict network conditions. For example, historic CSQI data can be used heuristically to predict network conditions based on geographic area (e.g., based on CellIDs), time of day, etc."<br><br>[0027] "Server 106A may determine CSQI's based on algorithms taking into account channel parameters directly measured by the server and/or channel parameter reports (e.g., RTCP SR/RR/XR) received from client devices 102"对比文件隐含公开了性能配置可以基于多种参数调整,包括网络参数(通道参数)、地理位置(CellID)、时间因素等预测性参数。虽然没有明确提及UE热参数、处理器负载、存储器可用性等参数,但CSQI的计算考虑了多种通道参数,这可以隐含地对应于性能配置文件的多元参数调整机制。
**技术特征M**:《隐含公开》<br>其中,发送所述调整的所述指示包括:至少部分地基于所述UE修改的性能配置文件,发送调整的帧速率性能指示符的指示[0031] "when connection quality becomes poor...the service may switch to a lower bitrate codec...When the connection gets better...server 106A may indicate to one or more client devices to increase the codec and/or bit-rate appropriately."对比文件隐含公开了基于连接质量调整编解码器和比特率。虽然没有明确提及"帧速率",但编解码器的切换直接影响视频/音频的帧处理速率,可以隐含地认为是帧速率调整的指示。
**技术特征N**:《隐含公开》<br>其中,发送所述调整的所述指示包括:至少部分地基于所述UE修改的性能配置文件,发送调整的分辨率性能指示符的指示[0050] "lowering a codec and/or bitrate may include changing a codec from AMR 7 (e.g., having a bit-rate of about 12 kbps) to AMR 3 (e.g., having a bit-rate of about 3 kbps)"对比文件隐含公开了编解码器调整。AMR编解码器会影响音频的采样率和质量,这可以类比于分辨率的调整。虽然主要涉及音频编解码器,但可以隐含地推断存在分辨率/质量级别的调整机制。
**技术特征O**:《直接公开》<br>其中,发送所述调整的所述指示包括:至少部分地基于所述UE修改的性能配置文件,发送调整的比特率性能指示符的指示[0031] "when connection quality becomes poor (e.g., falls below a configurable threshold), the service may switch to a lower bitrate codec. As another example, when connection quality improves (e.g., increases above a configurable threshold), the service may switch to a higher bitrate codec."<br><br>[0050] "lowering a codec and/or bitrate may include changing a codec from AMR 7 (e.g., having a bit-rate of about 12 kbps) to AMR 3 (e.g., having a bit-rate of about 3 kbps)"对比文件直接公开了基于连接质量动态调整比特率,从12kbps的AMR 7切换到3kbps的AMR 3。这明确公开了比特率性能指示符的调整指示。
