摘要： A system and method are provided for distributing wireless network access parameters in a multi-mode communications user terminal (UT). The method includes: establishing a link between a UT and a first communications network (i.e., a cellular network); accessing a parameters server via the first network; downloading access parameters for a wireless, second communications network (i.e., a Wireless Local Area Network); and, using the downloaded access parameters to establish a wireless link between the UT and the second communications network. The downloaded access parameters may include information such as a security key, Service Set IDentifier (SSID), traffic channel allocation, and optimization parameters including transmit power, quality of service (QoS) settings, and operational mode. Alternately, the database may cross-reference UT ID to parameters such as QoS, IP address, gateway information, subnet mask, Domain Name Server (DNS) information, or geographical location.

摘要： A user terminal establishes a session with a first access point (AP0) and obtains a token associated with modem configuration information used for radio communication. The user terminal thereafter establishes a connection with a second access point (AP1) by sending the token. AP1 receives the token, obtains the modem configuration information associated with the token, and initializes an air interface protocol stack with the modem configuration information to obtain a modem-specific protocol stack for the user terminal. AP1 sends a response indicating successful connection setup. The user terminal and AP1 thereafter communicate in accordance with the modem-specific protocol stack. AP1 may attempt to fetch the session for the user terminal from AP0. If this is successful, then AP1 updates the protocol stack with the session information to obtain a complete protocol stack for the user terminal. The user terminal and AP1 thereafter communicate with the complete protocol stack.

摘要： A system and method are provided for mobile Internet Protocol (IP) addressing, in a multi-mode wireless communications access terminal (AT). The method provides an AT with an IP address (ATA), and a care-of-address (CoA) in each of a plurality of networks. In one aspect, the AT selects a first network for transmission, from the plurality of networks. The AT sends an IP packet to a correspondent node (CN) via a first mobile node (MN) external device. Regardless of the network selected, the AT is able to use the ATA as a source address. Sending the IP packet to the CN may include creating a tunnel between the first MN and the HA. The IP packet is sent to the HA using the first CoA as a tunnel source address, and the HA sends the IP packet to the CN using the ATA as the source address.

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.
