摘要： A forward link (FL) RLP and a reverse link (RL) RLP that are different in design are used for data transmission on the forward and reverse links, respectively. The asymmetric RLP designs may be quantified by, e.g., different feedback mechanisms and/or different data transmission mechanisms used for these RLPs. The FL RLP may utilize a negative acknowledgment (NAK)-based feedback mechanism whereas the RL RLP may utilize an acknowledgment (ACK)-based feedback mechanism. The NAK-based FL RLP may transmit each RLP frame once in sequential order and retransmit RLP frames out of sequence when not received correctly. The ACK-based RL RLP may transmit RLP frames in sequential order, one frame at a time until the frame is received correctly or the maximum number of transmissions have been attempted. Timers with adaptive values computed based on actual traffic conditions may be used to facilitate data transmission by the NAK-based FL RLP.

摘要： The disclosure is directed to methods and apparatuses for seamless and efficient wireless handoffs of an access terminal between access points in a communication network. The access points include memory configured to buffer packets received from a network for the access terminal, a processor configured to queue one of the packets for over the air transmission to the access terminal and fragment the data in the queued packet into multiple frames, and a transmitter configured to transmit the framed data over the air to the access terminal. The processor is further configured to maintain an indicator relating to the portion of the data in the queued packet that remains to be transmitted.

摘要： Methods of handing off an access terminal in a meshed wireless system is disclosed. Data that is received by an access point in the meshed wireless system may be routed to an access terminal via a downstream serving access point. The access point may also be configured to communicate a connection state of the access terminal to a target access point if a handoff of the access terminal from the serving access point to the target access point is requested.

摘要： Methods, apparatus, systems and computer program products are defined that provide for in-order deliver of data packets during hand-off. The aspects provide for in-order delivery at Forward Link Serving eBS/Data Attachment Point (FLSE/DAP) switch and Reverse Link Serving eBS/Data Attachment Point (RLSE/DAP) switch. As such, present aspects provide for significant improvement in the throughput of applications, such as applications relying on Transmission Control Protocol (TCP), during handoff, in such networks as Ultra Mobile Broadband (UMB) and the like.

摘要： Methods and systems enable receiving on mobile devices credits, tokens or coupons from mobile TV broadcast service providers. Credits may be delivered via direct unicast messages such as SMS or e-mail, or via broadcast provisioning messages. Subscription response messages may be used to deliver credits to mobile devises which transmit a request for service. Broadcast service providers may push credits to mobile devices by transmitting a solicited pull message or a credit grant push message. Credits may be sent to mobile devices within a credit response message or a long term decryption key message. Credits may be used a purchase transaction, with the broadcast service provider controlling redemption of credits by sending an a long term decryption key message via a unicast network or a short term decryption key message via the broadcast network to cause mobile devices to decrement their stored credits.

摘要： Techniques for performing location logging and location and time based filtering are described. In one design of location logging, a terminal periodically determines its location, e.g., during its paging slots. The terminal determines whether there is a change in its location and stores its location if a change in location is detected. In one design of location and time based filtering, the terminal obtains a location and time criterion with a target area and a time period. The terminal determines its location during the time period, e.g., based on the location log. The terminal evaluates the location and time criterion based on the target area and its location during the time period, e.g., based on at least one sector ID for the target area and one or more sector IDs for its location. The terminal determines whether to download and/or present broadcast information based on the result of the evaluation.

摘要： Methods and systems enable receiver devices to receive electronic coupons from mobile TV broadcast service providers. Coupon templates may be broadcasted to mobile devices. Coupon templates may be used to communicate with coupon managers to receive digitally signed coupons. Coupon managers may use received data to create digitally signed coupons for delivery to receiver devices via a unicast networks. Digitally signed coupons may also be broadcasted to receiver devices. A receiver device may verify received electronic coupons using the digital signature to identify those coupons intended for them. The electronic coupons may be redeemed at a point of sale. Merchants may locally verify coupons using their digital signature. Coupon digital signatures may be generated using a chain of X.509 certificates leading to a root X.509 coupon-signing authority to enable recipients to confirm that coupons originated from a trustworthy entity.
