Abstract: A wireless device receives a request to originate a data call, e.g., from the user or a higher layer application. If origination control is not to be applied, then the wireless device originates the data call immediately. Otherwise, the origination of the data call is controlled based on prior data call origination attempts that are applicable to the data call. For example, the wireless device may originate the data call immediately if (1) the most recent origination attempt was successful or (2) the most recent origination attempt was unsuccessful but a predetermined time period has elapsed since this unsuccessful origination attempt. If the most recent origination attempt was unsuccessful and the predetermined time period has not elapsed, then the wireless device may (1) wait until this predetermined time period elapses and then originate the data call or (2) reject the data call.

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 select the 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: 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. The terminal attempts origination of the call on the selected wireless network. 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. 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: 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 is adapted to avoid unusable wireless communications systems during system acquisition. The mobile station includes processing circuitry and a memory storing a preferred roaming list and system avoidance data. The system avoidance data identifies unusable systems and includes corresponding avoidance criteria. The processing circuitry is adapted to select a system from the preferred roaming list in accordance with a predetermined system acquisition procedure. The selected system is skipped if corresponding avoidance criteria is satisfied. If the selected system is usable, the mobile station may attempt to acquire and register with the selected system. The processing circuitry is further adapted to add systems to the system avoidance data in response to a communications failure, and remove systems from the system avoidance data when corresponding avoidance criteria is no longer satisfied. The avoidance criteria may include a time period during which the corresponding system is unusable.

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: In a mobile station having an acquired wireless communications system, the mobile station performs preliminary searches for more desirable wireless communications systems in between paging channel and quick paging channel assigned slots, while successfully monitoring the mobile station's assigned slots. The mobile station then analyzes the preliminary search results and attempts to acquire the more desirable wireless communications systems that meets preliminary search criteria. The mobile station includes a communications transceiver that facilitates wireless communications with a local base station and processing circuitry adapted to control a slotted operation mode of the mobile station. The processing circuitry is adapted to instruct the communications transceiver to listen for incoming messages from the acquired communications system during slot modes and listen for candidate communications systems during slot-off modes. The preliminary searches include performing tests on the signal received on a candidate communications system channel. The tests may include measuring the signal strength, calculating the ratio Ec/Io and demodulating a synchronization signal.

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.

Abstract: Methods, devices and computer program products are disclosed that allow for wireless communication devices to operate more robustly in the slotted mode of operation in the event of network system loss. Specifically, present aspects require the wireless device to move to or remain in the slotted mode of operation as opposed to immediately entering into a system determination/acquisition mode upon failing to acquire an active set pilot during a slotted wake-up. By moving to the slotted mode of operation or providing for additional slotted-wake-ups, a number of attempts at acquiring the active set pilot can be performed before declaring the system as lost, thereby allowing for fading channel conditions to prevail without the need to re-acquire the lost system or otherwise acquire another system. Since the performance of the slotted mode is less power intensive than acquiring or re-acquiring a system, a substantial power savings is realized.
