    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: Techniques for performing automatic call origination for multiple wireless networks are described. A terminal automatically originates a call and supports fallback in case of call origination failure. The terminal selects the most preferred wireless network for the call based on network availability and network selection information (512). The terminal attempts origination of the call on the selected wireless network (514). If the call origination fails, then the terminal may select an alternate wireless network based on network availability and the network selection information and may attempt origination of the call on the alternate wireless network (518). If a VoIP call is preferred over a circuit-switched voice call, then the terminal may first attempt origination of a VoIP call on a packet-switched wireless network. If the VoIP call fails, then the terminal may attempt origination of a circuit-switched voice call on a circuit-switched wireless network.

    Abstract: A mobile station includes processing circuitry and a memory storing a preferred roaming list and system priority data. The processing circuitry is adapted to detect a communications event for a currently selected wireless communications system and update an entry in the system priority data to reflect the occurrence of the detected communications event. The use of stored statistical information improves the efficiency of the system selection and acquisition process. In operation, a group of wireless communications systems is selected from the preferred roaming list in accordance with a predetermined system acquisition procedure. The group is reprioritized using the priority data and the mobile station attempts to the selected wireless communications system having the highest priority in the reprioritized group. The reprioritization may include sorting the group using the priority data and removing systems from the group that do not meet certain priority criteria.

    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 call origination scheme (300) for a wireless telephone lists the number of silent redials to make (302), preferred mode (analog, digital, and so on) (304), and so on. Each telephone number which can be dialed by the wireless telephone is associated (102) with a scheme, and data representative of this association (104) are stored in the telephone. When a number is entered into the telephone (106), as be depressing a sequence of keys on a keypad, the telephone determines (108) the scheme associated with that number and places the call (110) according to that scheme.
