Abstract:
Procedimiento para originar una llamada telefónica inalámbrica, que comprende: (a) asociar (102) por lo menos: (1) un primer sistema de iniciación de llamadas con por lo menos un primer número de teléfono posible al cual se va a llamar y (2) un segundo sistema de iniciación de llamadas con por lo menos un segundo número de teléfono posible al cual se va a llamar; (b) almacenar (104) datos representativos de las asociaciones en un teléfono inalámbrico; (c) introducir (106) uno de los números de teléfono en el teléfono inalámbrico; (d) determinar (108) el sistema de iniciación de llamadas asociado con el número de teléfono introducido y (e) efectuar (110) la llamada según el sistema de iniciación de llamadas asociado; caracterizado porque: cada sistema de iniciación de llamadas incluye por lo menos uno de los elementos siguientes: (a) un número de intentos de iniciación (702) si el primer intento de iniciación resulta infructuoso, (b) una modalidad de servicio preferida (704) relativaa la tecnología que se va a utilizar, y (c) si debe esperar al servicio si no está disponible inmediatamente (706).
Abstract:
A wireless communication device selects another service provider system when the MWCD has not changed its geographic position more than a threshold level.
Abstract:
A wireless communication device has one or more predetermined patterns of key operation that are required to perform the function associated with the key. For example, activation of a power key on (114) a wireless communication device may be intentional or inadvertent. The wireless communication device requires activation of the selected key with a predetermined pattern of operation in order to qualify as an intentional act by the user. The predetermined patterns of operation may be varied in accordance with different conditions of the wireless communication device. The predetermined pattern of operation may require continuous activation for a predetermined period of time, multiple activation of the selected key within a predetermined period of time, simultaneous activation of multiple keys, sequential activation of multiple keys, or the like. The wireless communication device may also utilize a display to request confirmation by the user of a selected action.
Abstract:
One aspect of the invention provides a system, apparatus and method that allow a wireless communication device to intelligently search for and select a communication cell based on a system identifier (SID) and network identifier (NID) order of preference rather than just pilot signal strength. Generally, a mobile device scans a frequency channel associated with the highest preferred SID/NID for pilot signals at different PN offsets. The cell associated with the strongest pilot signal detected is queried to determine whether it belongs to the SID/NID sought. If the selected PN offset belongs to a cell associated with the SID/NID sought then it is used for communications. Otherwise, the SID/NID identification process is repeated for the next strongest PN offset detected on the same frequency channel. If no pilot signals meeting these criteria are found in the frequency channel, the next highest preferred SID/NID is selected and the process is repeated.

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.
