摘要： A method supports scalable and reliable multicast in a wireless network with a large bandwidth-delay product. In this method, acknowledgement packets from different receivers experiencing the same number of data packets lost are assigned the same time slots. This method can be combined with other loss recovery techniques, such as forward error correction (FEC) recovery, proactive protection, feedback suppression and collision detection. Scalability is achieved as bandwidth usage relates only to the number of packet s transmitted, rather than the number of receivers.

摘要： Cryptographically Protected Prefixes (CPPs) are used to create IP addresses preventing any correlation between a CPP IP address (54) and a host's geographic location. An IP address is subdivided into address prefixes of multiple segments. Each segment is encrypted with a cryptographic key known only to a subset of routers in the access network domain (or Privacy Domain). Therefore, each router obtains the information it needs to forward a packet of information, but not any additional information.
摘要翻译：密码保护前缀（CPP）用于创建IP地址，以防止CPP IP地址（54）和主机的地理位置之间的任何相关性。 IP地址被细分为多个段的地址前缀。每个段都使用仅在接入网络域（或隐私域）中的路由器的一部分已知的加密密钥进行加密。因此，每个路由器获得转发一个信息包所需的信息，但没有任何附加信息。

摘要： Methods, components, and systems for efficient authentication, either through a digital signature or message authentication codes, and verification of a digital stream sent from a source to a receiver via zero or more intermediaries, such that the source or intermediary (or both) can remove certain portions of the data stream without inhibiting the ability of the ultimate receiver to verify the authenticity and integrity of the data received. According to the invention, a source may sign an entire data stream once, but may permit either itself or an intermediary to efficiently remove certain portions of the stream before transmitting the stream to the ultimate recipient, without having to re-sign the entire stream. Applications may include the signing of media streams which often need to be further processed to accommodate the resource requirements of a particular environment. Another application allows an intermediary to choose an advertisement to include in a given slot.

摘要： Active scanning method in a wireless network for fast determining available access points (106, 806) using inter-AP (Access Point) communication is described. In the scanning method, a mobile station (102, 802) sends Probe Request for Proxy frame to the current AP (104, 804) serving the mobile station (102, 802). In response to the Probe Request for Proxy frame, the current AP (104, 804) send Proxy Probe Request packet to the appropriate APs (106, 806). In response to the Proxy Probe Request packet, the neighbor APs (106, 806) send Probe Response frame to the mobile station (102, 802) on its operating channel. Since the mobile station (102, 802) moves to the channel being examined after sending the Probe Request for Proxy frame, it receives the Probe Response frame if it is in the coverage area of the neighbor AP (106, 806). The content of Probe Response frame provides the mobile station (102, 802) with the information to be used in handoff decision and network join procedures. Thus, the mobile station (102, 802) neither has to move to the channel to be examined nor send Probe Request frame on that channel. This enables active scan to be initiated even when the neighbor AP (106, 806) is operating in PCF (Point Coordination Function) and the network is in CFP (Contention Free Period), during which unassociated mobile stations (including the scanning mobile station) cannot send packets.
摘要翻译：描述了使用AP（接入点）通信来快速确定可用接入点（106,806）的无线网络中的主动扫描方法。在扫描方法中，移动站（102,802）向服务于移动站（102,802）的当前AP（104,804）发送用于代理帧的探测请求。响应于针对代理帧的探测请求，当前AP（104,804）向适当的AP发送代理探测请求分组（106,806）。响应于代理探测请求分组，相邻AP（106,806）在其操作信道上向移动台（102,802）发送探测响应帧。由于移动站（102,802）在发送代理探测请求帧之后移动到被检查的信道，所以如果它在邻居AP（106,806）的覆盖区域内，它接收探测响应帧。探测响应帧的内容为移动台（102,802）提供要用于切换决策和网络连接过程的信息。因此，移动台（102,802）既不必移动到要检查的信道，也不在该信道上发送探测请求帧。即使当相邻AP（106,806）在PCF（点协调功能）中操作并且网络处于CFP（无争用周期））时，也可以启动主动扫描，在此期间，未关联的移动站（包括扫描移动站）无法发送数据包。

摘要： In a fast active scanning wireless network apparatus and method for quick determination of available access points (20), information about a candidate set of available access points (20) is obtained, and a candidate access point is identified from the candidate set. A mobile station (10) then queries the candidate access point with a probe request that designates the candidate access point as a sole responder. The probe request prevents other access points from contending for the medium of communication between the mobile station and the designated sole responder access point by excluding the attempt by other access points (20) to transmit probe responses. The apparatus and method thus increases the probability of a fast and successful probe request from the mobile station and subsequent response from the designated access point (20). The designated access point may also respond with a probe response of high priority, preventing intervention of communication.
摘要翻译：在用于快速确定可用接入点（20）的快速主动扫描无线网络装置和方法中，获得关于可用接入点（20）的候选集合的信息，并且从候选集合识别候选接入点。然后，移动站（10）用指定候选接入点的探测请求作为唯一响应者来查询候选接入点。探测请求通过排除其他接入点（20）发送探测响应的尝试来防止其他接入点竞争移动台和指定的唯一响应者接入点之间的通信介质。因此，装置和方法增加了来自移动台的快速和成功的探测请求的概率以及从指定接入点（20）的后续响应。指定的接入点也可以以高优先级的探测响应进行响应，防止通信干扰。

摘要： Packet communication method and system in which a packet destined for a terminal is provided service according to a service table indexed by packet classification and the terminal's power mode. The service table may specify for a connection a predetermined quality of service or discarding the packet. For a power mode having an alerting (i.e., paging) mechanism, the service may include alerting the terminal. The service table may also include a network edge point's own service requests and service requests from terminals, provisioning servers, and handoff sources. For a multicast or broadcast packet, as each terminal may be in a different power mode, the associated service in the service table may therefore be different for each terminal. In that case, the packet is provided with service so that any given terminal is provided with at least the quality of service specified in the service table. Thus, a multicast or broadcast packet is discarded when the service specified for all terminals is "discard." Each terminal is alerted, however, if the associated service includes alerting the terminal. During handoff, a part of service table associated with the terminal can be transferred from the handoff source to the handoff destination.
摘要翻译：分组通信方法和系统，其中根据由分组分类索引的服务表和终端的功率模式，向目的地为终端的分组提供服务。服务表可以为连接指定预定的服务质量或丢弃该分组。对于具有警报（即寻呼）机制的电力模式，该服务可以包括提醒终端。服务表还可以包括来自终端，配置服务器和切换源的网络边缘点自己的服务请求和服务请求。对于多播或广播分组，由于每个终端可能处于不同的功率模式，因此对于每个终端，服务表中的相关联的服务可能是不同的。在这种情况下，分组被提供服务，使得给定终端至少提供服务表中规定的服务质量。因此，当为所有终端指定的服务为“丢弃”时，组播或广播分组被丢弃。然而，每个终端被警告，如果相关联的服务包括警告终端。在切换期间，与终端相关联的服务表的一部分可以从切换源传送到切换目的地。

摘要： A method and communication system for supporting dormant mode are described. Li one embodiment, the communication system comprises a wireless station operable in a power savings mode and group of access points. Each group of access points comprises one or more access points with at least one group of access points having at least two access points. Ranges for the one or more access points in each of the groups define a paging area for each group, wherein one access point uses a paging channel for paging the wireless station when the wireless station is in the power savings mode and is in the paging area associated with the one access point. The wireless station performs a handoff procedure when the one access point is not in the same group of access points as the access point associated with the wireless station prior to the wireless station entering the power savings mode and does not perform a handoff procedure when the one access point is in the same group of access points as the access point associated with the wireless station prior to the wireless station entering the power savings mode.
