Abstract: A method and system provides for efficient data throughput by avoiding unnecessary data sub-packets transmission while not missing new data packets. The method and system distinguishes between a sub-packet for a current data packet and a sub-packet for a new data packet by assigning different codes to them. When a currently received sub-packet and a previously received sub-packet for a previously decoded data packet have equivalent codes, the remote station sends (506) an acknowledgement signal to the base station, preventing unnecessary sub-packets transmission. When the currently received sub-packet and the previously received sub-packet have different codes, the remote station sends (510) an acknowledgement signal, if the remote station can decode the new packet from the current sub-packet. Otherwise, the remote station sends (516) a negative acknowledgement signal to the base station, and requests more sub-packs for the current packet if the limit on number of transmission for currently received sub-packet has not reached.

Abstract: Embodiments disclosed herein relate to providing dynamic assignment of home agent and home address in wireless communications, such that a mobile node away from home may receive local access services from a visited network. In an embodiment, a mobile node accesses a visited network. The visited network authenticates the mobile node with its home network. The visited network then assigns a visited home agent and a home address for the mobile node. The mobile node subsequently performs secure binding with the visitor home agent. The mobile node proceeds with communications using the visitor home agent and home address.

Abstract: Techniques for minimizing call setup latency are disclosed. In one aspect, multiple signaling messages are encapsulated and sent as a single message thus reducing the total delay incurred by sequential transmission. In one embodiment, an encapsulation message includes a field indicating the number of messages encapsulated therein. In one example, the encapsulation is performed at a Link Access Control (LAC) layer. Alternate embodiments may perform encapsulation at an alternate layer.

Abstract: Method and apparatus for secure transmissions. Each user is provided a registration key. A long-time updated broadcast key is encrypted using the registration key and provided periodically to a user. A short-time updated key is encrypted using the broadcast key and provided periodically to a user. Broadcasts are then encrypted using the short-time key, wherein the user decrypts the broadcast message using the short-time key.

Abstract: Techniques for synchronization of stored service parameters are disclosed. In one aspect, a configuration identifier is transmitted (370) from a mobile station (106) to a base station (104), and compared with an identifier generated in the base station (380). If the identifiers match, the configuration is used for communication (390). In another aspect, the identifier is generated by selecting an identifier associated with a configuration from a configuration table (610). In yet another aspect, the identifier is generated by computing a cyclic redundancy check (CRC) of the configuration (320). Various other aspects are also presented. These aspects have the benefit of preventing attempted use of unsynchronized stored service parameters and associated call setup failures and subsequent renegotiation, with the net effect of reducing call setup time and more efficient use of system resources.

Abstract: Embodiments disclosed herein relate to a new set of radio link protocols (RLPs) configured to provide for efficient data transmission in a multi-link communication system. In an embodiment, an upper-layer packet is segmented into link-layer packets to be transmitted over a plurality of communication links, each including a first sequence number in accordance with a predetermined order. A second sequence number is further added to each link-layer packet to be transmitted for the first time. The second sequence number is configured to be in a sequence space associated with a particular communication link, and may be used for detection of missing packets.

Abstract: A method and apparatus for requesting PPP instances from a packet data services network includes a mobile station configured to send an origination message to a packet data service node (PDSN) at which it has arrived upon leaving the vicinity of another PDSN. The message informs the new PDSN of the new location of the mobile station and indicates both the number of dormant PPP instances associated with the mobile station and a service reference identifier for each such PPP instance. A flag within the message may be used to indicate whether the PPP instances are dormant (i.e., whether the mobile station is engaged in a call).
