摘要： An improved method and system for determining round-trip time (RTT) during a radio link protocol (RLP) wireless communication link. The RTT estimate is negotiated by both sides of the RLP communication link without the need for the 3-way handshake generally required for RLP synchronization. The method includes techniques used by both sides of the RLP communication link to dynamically update and refine their initial, negotiated RTT estimates.

摘要： A method and system for a handoff in a broadcast communication system is disclosed. A subscriber-assisted handoff is impractical in a broadcast communication system due to e.g., a high signaling load, a difficulty to synchronize the broadcast transmission. On the other hand, the small number of broadcast channels enables the subscriber station to perform the handoff autonomously. While performing a handoff between broadcast transmissions, a disruption of service occurs due to lack of synchronization among the broadcast transmissions. To reduce the service disruption, upon detecting a need for handoff, the lower layers inform the application layer about the forthcoming handoff. The application layer thus may take measures to reduce or prevent the disruption.

摘要： Techniques for retransmitting data via RLP in a CDMA (e.g., cdma2000) system with a first retransmission mechanism provided by the RLP and a second retransmission mechanism provided by an HARQ-CF. In one method, missing RLP frames are first detected (e.g., by a receiver RLP). A dynamic timer is then maintained (e.g., by a receiver HARQ-CF) for each RLP frame detected to be missing. The dynamic timers are event-driven and have variable time durations. Each dynamic timer is updated based on events known to the receiver HARQ-CF. Fixed timers with fixed time durations may also be maintained (e.g., by the receiver RLP) for the missing RLP frames. Whether or not a missing RLP frame is lost is determined based on the dynamic timer and the fixed timer (if any) maintained for the RLP frame. A NAK may be issued for retransmission of each RLP frame deemed to be lost.

摘要： Method and apparatus for data packet communications in a communication system. Packets are received at a gateway having an Internet Protocol (IP) destination address and Network Access Identifier (NAI). The gateway maps the received NAI to a local network, such as supported by a Network Address Translator (NAT). The gateway then converts the destination address to a NAT address of the local network. The gateway also adds a port number that allows the NAT to identify the target recipient. The mapping within the gateway is created and maintained as Mobile Stations send registration requests upon arrival within a local network. In one embodiment, the registration request is a Session Initiation Protocol (SIP) registration.

摘要： A novel method and apparatus for transmitting voice traffic and data traffic over a circuit-switched network and a packet-switched network are presented. A new service option is introduced that allows a circuit-switched network to strip off IP/UDP/RTP header information from an internet protocol packet that may or may not be carrying multimedia payloads. Selectively eliminating the reliability measures in the RLP layer allows the circuit-switched network to reduce the delay associated with data traffic, and thus satisfy the more stringent delay requirements of voice traffic.
