Abstract:
Methods and systems are disclosed that provide refresh procedure to ensure successful subscriber identity module activation during active data and voice calls. A request to update a subscription data on a network application housed on a Universal Integrated Circuit Card (UICC) is processed by a mobile equipment (ME) and is forwarded to the UICC smart card. The UICC smart card updates the requested parameters on the network application and probes the ME to read the updated parameters. The ME polls its services to check if the network application can be refreshed. If the network application was not previously activated, the voting mechanism on refresh procedure is skipped and the ME proceeds with refreshing the network application for updating its copy of the subscription information.
Abstract:
This disclosure provides systems, methods, and apparatus for refreshing information stored on a smart storage device. In one aspect a smart storage device is provided that is configured to be coupled to a wireless communications apparatus operating in a wireless communications network. The smart storage device includes a memory configured to store network access information for accessing services of the network. The smart storage device further includes a controller configured to send a message to the wireless communications apparatus including data notifying the wireless communications apparatus of an update to the network access information. The data further includes a command that the wireless communications apparatus suspend an active operation of the wireless communications apparatus and initiate updating information managed by the wireless communications apparatus based on one or more conditions. The updating of the information is based on at least a portion of the updated network access information. Other aspects, embodiments, and features are also claimed and described.
Abstract:
Aspects of the present disclosure are directed to a polling interval negotiation scheme between a universal integrated circuit card (UICC) and a wireless terminal. A wireless terminal and a UICC are communicating at a first polling interval. The wireless terminal may send a proposed polling interval to the UICC. The wireless terminal determines a response of the UICC to the proposed polling interval, and communicates with the UICC at a second polling interval based on the response of the UICC.
Abstract:
Methods and apparatus for initializing a SIM card may include sending a request to read a file from the SIM card. In addition, the methods and apparatus may include receiving a SIM version identifier for the file from the SIM card and determining whether the SIM version identifier matches a cached version identified in a cache. When the SIM version identifier matches the cached version identifier, the methods and apparatus may include accessing the file from the cache.
