    Abstract: 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.

    Abstract: A system for providing a dynamic multi-mode service acquisition capability to a subscriber station is provided. The subscriber station is capable of operating in two or more modes of operation. A time to scan condition is indicated while the subscriber station is operating in a current mode of operation having active and inactive states. Responsive thereto, the system stores state information for the current mode of operation, and attempts at least a partial acquisition of communications services in accordance with another mode of operation. The at least partial acquisition attempt is scheduled to be initiated while the subscriber station is operating in the inactive state in the current mode of operation, and completed before the subscriber station transitions back to the active state in the current mode of operation. If the acquisition attempt is successful, the subscriber station transitions to the new mode of operation, maintaining appropriate registration. If unsuccessful, the subscriber station uses the stored state information to resume operating in the current mode of operation.

    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.
