摘要： A roaming emulator provides a tool for emulating system determination for monitoring the operation of a wireless communication device (WCD) during system determination. A signal monitoring program and service selection protocol are stored, and a signal emulation module provides a signal emulation output in accordance with a predetermined set of data. A processing module performs a simulation of a service selection procedure based on the service selection protocol and performed in accordance with the signal monitoring program and the signal emulation output. A result of the service selection is provided by an output module. The emulator can provide emulated system scanning based on geographical or market location, and can emulate scenarios when channels from neighboring systems or markets “bleed” into the RF environment of the WCD.

摘要： A network operator identifier is used to uniquely identify each network operator to support international roaming. The network operator identifier includes (1) a Mobile Country Code (MCC) that identifies the country in which a network operator belongs and (2) a Network Operator Code (NOC), which may be a Mobile Network Code (MNC), that distinguishes network operators within a given MCC. Each network operator is assigned a unique combination of MCC and NOC that distinctly identifies the network operator, and the network operator identifier can be stored in a single entry in a preferred roaming list. The base stations of each network operator broadcast the network operator identifier in signaling messages. A mobile station receives a signaling message from a base station, obtains the network operator identifier, searches its preferred roaming list for an entry with the network operator identifier, and determines whether or not the current CDMA network is accessible.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
