### 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**: 一种用于用户设备UE的无线通信方法<br>**公开性判断**: 直接公开`[0002] The embodiments described herein relate generally to data communications...`<br>`[0025] In a further aspect, there is provided a computer-implemented method for providing data communication to and from a vehicle.`<br>`[0046] In a yet further aspect, there is provided a system for data communication across a plurality of communication links to and from a vehicle, involving at least one mobile device on the vehicle.`对比文件全文描述了一种为车辆及其上移动设备(即UE)提供数据通信的系统和方法。其技术领域、发明内容及具体实施方式均围绕“data communication to and from a vehicle”展开,这明确公开了涉及用户设备(移动设备)的无线通信方法。该特征在对比文件中与其在目标专利中同为通信方法的基础框架,作用相同。
**技术特征B**: 从基站接收数据传输<br>**公开性判断**: 直接公开`[0090] ...vehicle 1 variously enters and exits the range of various cellular networks provided by respective signal towers.`<br>`[0091] ...vehicle 1 variously enters and exits the range of various network access points (e.g., cellular, WiFi, etc.) through which communication links may be established.`<br>`[0144] FIG. 2 depicts a communication system... which may be in communication with signal towers associated with carriers A, B, and C.`对比文件多次描述了车辆(及其上的设备)通过蜂窝网络信号塔(即基站)接收数据。信号塔(signal towers)是基站的具体表现形式。该特征在对比文件中用于建立通信链路以接收数据,与目标专利中从基站接收数据的作用相同。
**技术特征C**: 将所述数据传输存储在所述UE的应用处理器AP的存储器中<br>**公开性判断**: 隐含公开`[0194] ...a mobile device 802a ... 802n on the vehicle (e.g., with a data source 832 or a data recipient 834) may be communicated across an adaptive bonded communication link...`<br>`[0195] ...data being transmitted to a mobile device 802 on the vehicle from a data source 832 across a network 850 may first be received at the second utility 102... The first utility 100 then reassembles the received data and transmits the data to the mobile device 802.`<br>`[0200] The vehicle data communication subsystem 806 may be configured to communicate data between first utility 100 and a mobile device 802.`对比文件明确指出移动设备(UE)在车辆上通过通信系统接收数据(如来自数据源的数据)。接收到的数据必然需要存储在移动设备的某个位置以供处理和使用。虽然未明确提及“应用处理器(AP)的存储器”,但移动设备(如智能手机、平板电脑)均包含应用处理器及其关联的存储器(如系统内存、闪存)用于存储和处理应用程序数据。本领域技术人员可以毫无疑义地确定,通过无线网络接收到的数据传输后,会被存储在UE的存储器中,这是数据被使用的必要前提。因此,该技术特征被对比文件隐含公开。
**技术特征D**: 由所述UE的所述AP至少部分地基于调制解调器缓冲区的大小来识别上行链路许可<br>**公开性判断**: 隐含公开`[0106] Data communications may be distributed over the available communication links based on one or more factors including, e.g., ... available bandwidth (measured and/or predicted), bandwidth usage (measured and/or predicted)...`<br>`[0222] ...adaptive link management subsystem 818 may be configured to control the distribution of data communications over the available communication links forming a bonded communication link.`<br>`[0229] ...the system may employ various techniques (e.g., including various algorithms and heuristics) to differentiate between bulk transfers ... and interactive transfers ... For example, techniques may involve monitoring the duration of connections, port numbers used, transport protocols used, frequency/size of packets, contents of packets, amongst other factors.`对比文件描述了基于可用带宽、数据使用情况等因素来分配和管理通信链路。管理数据流量的过程(如判断是批量传输还是交互式传输)本质上涉及对数据量(可类比为缓冲区中的数据量)的监控和评估。虽然未明确使用“调制解调器缓冲区”和“上行链路许可”的术语,但其“自适应链路管理子系统”(adaptive link management subsystem)根据数据通信需求和链路特性动态分配链路资源的过程,在逻辑上等同于一个实体(可类比为系统中的控制模块,该模块的功能可能由AP或与AP协同的模块实现)基于当前待发送数据的情况(这必然与缓冲区状态相关)来决定如何使用上行链路资源(即识别上行链路许可)。本领域技术人员可以合理推断出,为了实现这种动态、自适应的链路分配,系统需要知晓待发送数据的状态,而这与基于缓冲区大小来识别上行链路许可是相通的。
**技术特征E**: 由所述AP至少部分地基于所识别的上行链路许可来确定是否向所述调制解调器发送数据<br>**公开性判断**: 隐含公开`[0200] The vehicle data communication subsystem 806 may be configured to communicate data between first utility 100 and a mobile device 802.`<br>`[0222] The adaptive link management subsystem 818 may be configured to ... control the distribution of data communications over the available communication links...`<br>`[0229] ...the system may employ various techniques ... to differentiate between bulk transfers ... and interactive transfers ...`对比文件描述了车辆数据通信子系统(vehicle data communication subsystem)在车辆上的第一设施(first utility 100)和移动设备之间通信数据。同时,自适应链路管理子系统控制着数据在可用链路上的分发。结合对特征D的论述,既然系统能够基于数据状态(隐含缓冲区状态)来识别和分配上行资源(隐含上行链路许可),那么负责与应用层交互的实体(可类比为AP)自然会基于这个资源分配结果(即所识别的上行链路许可)来决定何时、向哪个底层通信模块(可类比为调制解调器)发送多少数据,以实现流量控制和管理。例如,当系统判定当前链路资源紧张或分配给某类数据的带宽有限时,AP就会暂缓或减少向调制解调器发送相应数据。
**技术特征F**: 以及当所识别的上行链路许可超过阈值时由所述AP发送所述数据<br>**公开性判断**: 隐含公开`[0106] Data communications may be distributed over the available communication links based on one or more factors...`<br>`[0222] ...adaptive link management subsystem 818 may be configured to control the distribution of data communications over the available communication links...`<br>`[0240] 1. Monitor the lifetime of a connection and the size of the data transferred. For example, the first 100 KB of each TCP flow could be given high priority, and any subsequent bytes could be treated as a bulk transfer and thus be low priority.`对比文件描述了基于多种因素和规则进行数据分发和优先级管理。其中提到了监控连接时长和数据传输大小,并为不同类型的数据设置优先级。这里的“优先级”和“分配的资源量”可以理解为一个动态的“许可”机制。虽然没有明确的“阈值”一词,但“第一100KB给予高优先级”这类规则本身就隐含了阈值判断(即数据量是否超过100KB)。因此,可以合理推断,当系统识别出的可用于发送某类数据的资源(上行链路许可)满足一定条件(例如,资源量超过某个保证该数据能被优先或及时发送的临界值,即“阈值”)时,负责数据提交的实体(可类比为AP)就会执行发送操作。
**技术特征G**: 识别所述上行链路许可包括从所述调制解调器接收上行链路许可<br>**公开性判断**: 隐含公开`[0144] ...modems 1 ... x, which may be in communication with signal towers associated with carriers A, B, and C.`<br>`[0222] The adaptive link management subsystem 818 may be configured to form and maintain adaptive bonded communication links. In particular, adaptive link management subsystem 818 may be configured to identify available communication links (e.g., based on link availability data received from first utility 100)...`对比文件描述了调制解调器(modems)与信号塔通信以建立链路。自适应链路管理子系统需要识别可用通信链路,其依据可能包括从第一设施(first utility 100,位于车辆上,可能集成或连接着调制解调器)接收到的链路可用性数据。本领域技术人员可以合理推断,调制解调器作为直接与无线网络交互的硬件,能够感知网络侧的调度和资源分配情况(如下行控制信令中的上行授权信息)。位于车辆上的控制实体(如第一设施中的管理模块,其功能可由AP或与AP紧密协作的模块承担)可以从调制解调器接收这些关于上行链路可用性的信息,从而“识别上行链路许可”。这符合无线通信系统中应用层/高层从物理层/底层获取资源状态信息的常规架构。
**技术特征H**: 识别所述上行链路许可包括由所述AP确定上行链路许可<br>**公开性判断**: 隐含公开`[0106] Data communications may be distributed over the available communication links based on one or more factors including, e.g., costs involved with using particular communication links ..., available bandwidth ..., bandwidth usage ..., priority level of the communication, type of communication, user preferences ..., user status, network conditions ...`<br>`[0220] ...adaptive link management subsystem 818 may be configured to interoperate with the user profile subsystem 820 and/or the database 870 in controlling the distribution of data communications over the available communication links.`对比文件详细描述了基于成本、带宽、用户优先级、业务类型、网络状况等多种复杂因素,通过自适应链路管理子系统(可能位于云端或车辆端)来智能分配通信链路。这个过程不仅仅是接收底层信息,更是一个主动的、基于策略的决策过程。虽然该子系统可能不直接称为“AP”,但其决策逻辑和功能可以视作一个集中的资源管理器。在车辆端的实现中,这个管理功能的一部分很可能由车辆上的主处理器(即AP)来执行或参与执行。AP可以根据应用程序的需求、用户配置、缓存的数据量(隐含缓冲区状态)以及从网络侧或调制解调器反馈的链路状况,综合判断并“确定”当前应该使用多少上行资源,即确定上行链路许可。这体现了AP在流量控制中的主动性。
**技术特征I**: 所述数据包括与数据传输相关联的传输控制协议TCP数据或TCP确认ACK反馈<br>**公开性判断**: 直接公开`[0032] The plurality of communication links may include communication links utilizing at least one of (i) the transmission control protocol and (ii) the user datagram protocol.`<br>`[0240] 1. Monitor the lifetime of a connection and the size of the data transferred. For example, the first 100 KB of each TCP flow could be given high priority...`对比文件明确指出了通信链路可使用传输控制协议(TCP)。并且,在描述流量监控和优先级管理的例子中,直接提到了“TCP flow”。TCP流中自然包含TCP数据和TCP确认(ACK)反馈报文。因此,对比文件直接公开了所述数据包括TCP数据或TCP ACK反馈。
**技术特征J**: 所述数据包括传输控制协议TCP确认ACK反馈、蜂窝车联网C‑V2X数据、虚拟现实VR数据、扩展现实XR数据、超可靠低延迟通信ULLC数据或任何特定的业务类型/模式<br>**公开性判断**: 隐含公开`[0071] ...video streaming, or have a minimum packet loss requirement.`<br>`[0073] Additionally, there may be other data services for a vehicle (such as, e.g., security video, telemetry data, vehicle control data, television data, payment or other financial transaction data, etc.)...`<br>`[0225] For example, a user may be watching a video and requesting video data be transmitted...`<br>`[0254] ...latency requirement <100 ms`对比文件列举了多种需要通过其系统传输的数据类型和服务,包括视频流(可对应VR/XR数据)、安全视频、遥测数据、车辆控制数据(可对应C-V2X数据的部分范畴)、电视数据、支付数据等。同时,它还特别强调了某些服务对低延迟(latency requirement <100 ms)和低丢包率的要求,这对应了超可靠低延迟通信(URLLC,目标专利中为ULLC,应为笔误或同义)场景。虽然未明确使用“C-V2X”、“VR”、“XR”、“ULLC”这些标准术语,但所描述的数据类型和应用场景(车辆相关数据、视频流、低延迟关键数据)完全覆盖了这些术语所指代的内涵。本领域技术人员可以毫无困难地将对比文件中的具体示例映射到这些更上层的业务类型/模式分类中。
**技术特征K**: 为了确定是否从所述AP向所述调制解调器发送数据,所述AP被配置为:至少基于所述调制解调器缓冲区的一个或多个阈值来管理从所述AP到所述调制解调器的数据流量<br>**公开性判断**: 隐含公开`[0229] ...the system may employ various techniques (e.g., including various algorithms and heuristics) to differentiate between bulk transfers (e.g., background operating system updates or file downloads) and interactive transfers (e.g., foreground applications involving user input or output to the user, or basic services required by many applications such as a DNS service).`<br>`[0240] 1. Monitor the lifetime of a connection and the size of the data transferred. For example, the first 100 KB of each TCP flow could be given high priority, and any subsequent bytes could be treated as a bulk transfer and thus be low priority.`<br>`[0242] 3 . Parse the application layer protocol (e.g. HTTP), and prioritize the requests/responses that are smaller than a certain size.`对比文件描述了系统使用多种技术来区分批量传输和交互式传输,并基于数据大小(如100KB)、连接时长、协议类型等设置优先级规则。这些规则的核心是依据数据流的特征(大小、类型)来决定其处理优先级,这本质上是一种流量管理策略。虽然未提及“调制解调器缓冲区”这一具体组件,但流量管理的目的是为了避免网络拥塞、保证关键业务质量,其效果必然体现在控制提交给底层通信模块(调制解调器)的数据速率和时机上。而依据数据大小(如“小于特定大小”)进行判断的规则,正是基于“阈值”的管理思想。因此,本领域技术人员可以合理推断,负责执行这些应用层流量策略的实体(即AP),会被配置为基于一个或多个类似的“阈值”规则,来管理其向调制解调器发送数据的流量。
**技术特征L**: 所述数据包括与由所述调制解调器识别的指定应用相对应的任何所识别的应用数据<br>**公开性判断**: 直接公开`[0073] Additionally, there may be other data services for a vehicle (such as, e.g., security video, telemetry data, vehicle control data, television data, payment or other financial transaction data, etc.) which must be delivered and/or received at the vehicle.`<br>`-0225] For example, a user may be watching a video and requesting video data be transmitted from a data source 832 across the Internet.`<br>`[0240] ...to differentiate between bulk transfers (e.g., background operating system updates or file downloads) and interactive transfers (e.g., foreground applications involving user input or output to the user...`对比文件明确列出了多种具体的应用数据,如安全视频、遥测数据、车辆控制数据、电视数据、支付数据、视频流数据、操作系统更新、文件下载、用户交互数据等。这些数据都是由车辆上或为用户服务的特定应用(如安全监控应用、车机系统应用、娱乐应用、支付应用等)产生或消费的。虽然未明确描述“由调制解调器识别”这一动作,但在通信系统中,底层模块(如调制解调器或与其关联的分类器)根据数据包特征(如端口号、协议类型、IP地址等)识别其所属应用或业务类型,是实现优先级管理和流量控制的基础步骤。因此,对比文件直接公开了数据包括各种指定的应用数据。
**技术特征M**: 当所识别的上行链路许可为0时,由所述AP发送所述数据<br>**公开性判断**: 隐含公开`[0229] ...the system may employ various techniques ... to differentiate between bulk transfers ... and interactive transfers ...`<br>`[0240] 2. Monitor the port numbers and frequencies/sizes of packets sent back and forth. Interactive SSH sessions typically run over TCP port 22, and will tend to contain small packets (<100 bytes) sent to the server as the user types keyboard commands, with varying sizes of return packets (anywhere between 5 and 1000 bytes) containing responses to those commands.`<br>`[0242] 3 . Parse the application layer protocol (e.g. HTTP), and prioritize the requests/responses that are smaller than a certain size.`对比文件强调了对交互式传输(如SSH会话、小尺寸HTTP请求/响应)的优先级保障。交互式传输,特别是像TCP ACK、SSH命令响应、小HTTP请求这类数据,通常数据量很小但对实时性要求高。在目标专利中,特征M的上下文(结合说明书[0124]-[0127]段)是为了解决即使在上行资源紧张(许可为0)时,也要保证TCP ACK等关键小数据包的发送,以避免下行链路阻塞。对比文件通过优先级规则(例如,为小包或特定端口数据赋予高优先级)来实现类似目的:即使总体带宽受限(相当于上行许可紧张),系统也会优先保障这些关键的小数据包能够被发送出去。因此,可以合理推断,在对比文件的系统中,当资源管理器(功能上对应AP)识别出可用于某类低优先级大数据量的上行许可可能为0或极低时,它仍然会基于优先级规则,允许(即“发送”)那些高优先级的、小尺寸的交互式数据(如TCP ACK)。这隐含了“上行许可为0时仍发送特定数据”的逻辑。
