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： An apparatus and method of transmitting a Redirect message in a wireless communication system is described. A Redirect message is generated comprising an 8 bit MessageID field, a 16 bit StayAwayDuration field wherein the StayAwayDuration field indicates the units of second for which an access terminal will not make an access attempt at the sector sending this message, an 8 bit NumChannel field wherein the NumChannel indicates the number of channel records included in the message, an 8 bit RedirectReason field wherein the RedirectReason reflect the redirect reason and a Channel field wherein the Channel field indicates the channel that the access terminal should reacquire. The Redirect message is transmitted over a communication link.

摘要： Methods and apparatus for communicating between an access terminal (AT) and an Access Point (AP) are described. For communications over the air link, between an AP and an AT a PN (Pseudo-random Noise) code based address is used as an AP identifier, e.g., address. The PN code based address may be based on Pilot PN code based signals received from an AP. Thus, the PN based AP address may be determined from pilot signals received from an AP. The PN based AP address may be a shortened version of a PN code corresponding to an AP, a full PN code corresponding to an AP, or a value which can be derived in a known manner from a PN code corresponding to an AP.
