Problems solved by technology

For both methods, retrieving the session from the session holding access point or receiving session information from the user terminal incurs a delay
Additionally, sending session information from a session-holding access point or user terminal to a new access point consumes system resources

Embodiment Construction

[0023] The word "exemplary" as used herein means "serving as an example, instance, or illustration." Any embodiment or design described herein as "exemplary" need not be construed as being preferred or advantageous over other embodiments or designs.

[0024] Figure 1 shows a wireless communication network 100 with multiple access points that support communication for multiple user terminals. For simplicity, only one user terminal 110 and three access points 120a (AP0), 120b (AP1) and 120c (AP2) are shown in FIG. Typically, an access point is a fixed station used to communicate with user terminals, and may also be called a base station, a base transceiver system (BTS), a node B, or some other terminology. A user terminal (UT) may be fixed or mobile, and may also be called an access terminal (AT), a mobile station (MS), a user equipment (UE), a wireless device, a handset, or some other terminology. The user terminal can communicate with one or more access points on the forward link ...

Abstract

A user terminal establishes a session with a first access point (AP 0 ) 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 (AP 1 ) by sending the token. AP 1 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. AP 1 sends a response indicating successful connection setup. The user terminal and AP 1 thereafter communicate in accordance with the modem-specific protocol stack. AP 1 may attempt to fetch the session for the user terminal from AP 0 . If this is successful, then AP 1 updates the protocol stack with the session information to obtain a complete protocol stack for the user terminal. The user terminal and AP 1 thereafter communicate with the complete protocol stack.

Description

[0001] Cross reference of related applications [0001] This application requires the rights and interests of the U.S. Provisional Application No. 60 / 638,471 filed on December 22, 2004, entitled "CONNECTION SETUP USING FLEXIBLE PROTOCOLCONFIGURATION CDMA", and this provisional application is fully incorporated herein for reference. Technical field [0001] The present invention relates generally to communication, and more specifically, to a technique for establishing a connection in a communication system. Background technique [0002] In a communication system, in order to obtain various services such as voice and packet data, user terminals communicate with access points. Typically, a session is established for the user terminal in order to facilitate communication. As an integral part of session establishment, user terminals and access points can negotiate various configurable protocols and select parameters for these protocols. Generally, a session is considered to be a collecti...
