    Abstract: A preferred roaming list (PRL) carries system and acquisition records for wireless wide area network (WWAN) systems and wireless local area network (WLAN) systems, New system and acquisition records may be defined for WLAN. The PRL and system and acquisition records may be defined to be backward compatible with TIA-683-C. System and acquisition information for WLAN systems may be stored in the new system and acquisition records, respectively. Information used to perform encryption and/or authentication for WLAN systems may be stored in a separate WLAN authentication profile table. The system record for each WLAN system indicates a acquisition record and a profile record for that WLAN system, A network identifier table may also carry system records and profile records for WLAN systems. The system records carry information used for WLAN system selection and acquisition. The profile records carry information used to perform encryption and/or authentication for WLAN systems.

    Abstract: Techniques for performing system selection and acquisition are described. In one design, a terminal may obtain at least one system record for at least one system utilizing orthogonal frequency division multiplexing (OFDM) or single-carrier frequency division multiplexing (SC-FDM). Each system record may include system identification information for an associated system and an index for an associated acquisition record. The terminal may also obtain at least one acquisition record for the at least one system. Each acquisition record may include at least one value for at least one configurable system parameter, e.g., FFT size, cyclic prefix length, number of guard subcarriers, etc. The terminal may perform acquisition for the at least one system in accordance with the at least one system record and the at least one acquisition record. The system and acquisition records may be stored in a Preferred Roaming List (PRL) or a Most Recently Used (MRU) list.

    Abstract: Methods, apparatuses and computer program products for causing a subscriber station (100) to attempt to acquire one of a plurality of systems. The subscriber station (100) first detects an event that triggers use of a system acquisition schedule. The system acquisition schedule, which can be time based or sequence based, defines when to attempt to acquire a desired system. The subscriber station (100) attempts to acquire the desired system in accordance with the system acquisition schedule. The subscriber station (100) performs other functions when the system acquisition schedule does not indicate an attempt should be made to acquire the desired system. Such other functions can include attempting to acquire other systems when the system acquisition schedule does not indicate an attempt should be made to acquire the desired system.

    Abstract: A mobile station includes client circuitry for facilitating wireless communications with a wireless communications system, and a configurable system selection unit that executes a system selection and acquisition procedure. The configurable system selection unit includes a front end and a system selection core. The front end facilitates communications between the configurable system selection unit and the client circuitry. The system selection core is coupled to the front end and includes a script engine and a nonvolatile memory storing at least one script table. The script table includes a plurality of system selection event conditions and corresponding scripts that define a system selection and acquisition procedure. The script engine is adapted to detect an event condition and execute the corresponding script. The system selection core is adapted to receive a system selection script and store the received script in the script table, thereby altering the system selection and acquisition procedure.
