    Abstract: The present invention provides a scalable and reliable feedback suppression method for receiving and transmitting data block. The method comprises receiving at least one initial data packet of the data block which is sent by the transmitter to the multicast group of receivers; and sending at least one NAK packet indicating packet loss to the transmitter by at least one receiver of the multicast group, wherein the at least one NAK packet is sent in a single uplink time slot dedicated to said multicast group of receivers, and wherein the NAK packet is identical for all receivers of said multicast group.

    Abstract: A call flow is provided in a wireless communication system to enable quality of service (QoS) parameters to be retrieved and provided to a base station when a wireless device requests service. The QoS parameters may include or represent a QoS profile associated with the wireless device, a QoS profile associated with a user of the wireless device, or a QoS policy for a session involving the wireless device. The base station uses the QoS parameters to control access to the system by the wireless device. Another call flow is provided to transfer the QoS parameters from the base station to a packet control function for storage when a packet data session associated with the wireless device becomes dormant. If the packet data session is later reactivated, the QoS parameters are provided from the packet control function back to the base station.

    Abstract translation: 在无线通信系统中提供呼叫流程，以便当无线设备请求服务时，检索服务质量（QoS）参数并将其提供给基站。 QoS参数可以包括或表示与无线设备相关联的QoS简档，与无线设备的用户相关联的QoS简档，或者涉及无线设备的会话的QoS策略。 基站使用QoS参数来控制无线设备对系统的访问。 当与无线设备相关联的分组数据会话变为休眠时，提供另一个呼叫流程以将QoS参数从基站传送到分组控制功能以用于存储。 如果分组数据会话稍后重新激活，则QoS参数从分组控制功能提供回基站。

    Abstract: Content can be advantageously customized by use of an accompanying rich media file that characterizes segments in the content file. To perform such customization, the rich media file undergoes parsing (e.g., examination) to identify a location for an overlay in the least one segment of the content file. Thereafter, an overlay is inserted into the at least one content segment. In practice, the overlay is inserted to block objectionable material in the content segment, but the overlay can be inserted to add material, such as to insert an advertisement or a sub-title for example. Inserting the overlay can include physically overlaying a cover layer onto one or more frames of the content segment to add information or block objectionable material in the content segment.

    Abstract translation: 可以通过使用表征内容文件中的段的伴随的富媒体文件来有利地定制内容。 为了执行这样的定制，富媒体文件经历解析（例如，检查）以在内容文件的至少一个段中标识覆盖的位置。 此后，将覆盖物插入至少一个内容段。 在实践中，插入覆盖以阻止内容段中的令人讨厌的材料，但是可以插入覆盖以添加材料，例如插入广告或子标题。 插入覆盖可以包括将覆盖层物理地覆盖到内容段的一个或多个帧上，以在内容段中添加信息或阻止令人不快的材料。

    Abstract: In general, to provide acknowledgment information by a first wireless device, the first wireless device sends repeated instances of acknowledgment information in respective first and second frame structures, in response to receipt of first information from a second wireless devalue. In addition, the first wireless device also sends further acknowledgment information in the second frame structure that is responsive to second information received from the second wireless device.

    Abstract: In the context of IEEE 802.11 WLAN networks, enhancement to the Relaxed Deterministic Backoff (R-DEB) for random access of shared (Medium Access Control MAC) method. For all available candidate resource slots, a busy index is calculated that reflects the level of use/occupation in the past and infers a probability of use in the future by another concurring device. The method assumes the use of a sub-set of resource slots for transmission, and updates this set by replacing resource slots for which collisions are frequent with a not currently used candidate resource for which the busy index is the lowest. Passive Spoofing/overhearing of all resources for clear channel assessment (CCS) is used for resource monitoring purposes.

    Abstract translation: 在IEEE 802.11 WLAN网络的上下文中，对用于共享（媒体访问控制MAC）方法的随机接入的轻松确定性后退（R-DEB）的增强。 对于所有可用的候选资源时隙，计算反映过去使用/占用水平的繁忙索引，并推测未来由另一个同步设备使用的概率。 该方法假设使用资源时隙子集进行传输，并通过将忙碌索引最低的未使用的候选资源替换为频繁冲突的资源时隙来更新该集合。 用于明确渠道评估（CCS）的所有资源的被动欺骗/监听被用于资源监控。

    Abstract: A communications system includes a wireless telephony network and a wireless Local Area Network (LAN), both accessible by a mobile communications device (16). To facilitate transitioning of the mobile communications device to the wireless LAN from the wireless telephony network, the wireless LAN includes a beacon transmitter, which generates a synchronization channel having a pattern unique to the wireless LAN. The Wireless LAN synchronization channel is received at a first receiver in the mobile communications device together with a synchronization channel from the wireless telephony. The wireless LAN synchronization channel enables the mobile communication device to synchronize with, for transitioning to, the wireless LAN.
