Embodiment Construction

[0027] As mentioned above, devices evolve over time to support multiple configurations (eg, hardware and / or software configurations). For example, some mobile stations (MSs) support communication using multiple radio access technologies (RATs) in order to expand the services available to users. For example, a multi-mode MS may support Long Term Evolution (LTE) for broadband data services and Code Division Multiple Access (CDMA) for voice services. As modem features are added to support these services, the memory footprint on the modem side also increases. However, it is desirable to limit the amount of random access memory (RAM) required in order to minimize cost. Therefore, the problem to be solved is how to limit RAM usage while maintaining features (eg, modem features).

[0028] It is presented herein that by loading only the necessary feature set (e.g., necessary to support currently available radio access technologies (RATs)) into memory at startup (e.g., referred to he...

Abstract

Methods and apparatus are provided for device configuration (e.g., feature segment loading and system selection). Certain aspects of the present disclosure generally relate to operating a user equipment (UE) in a first radio access network (RAN) with a first set of modem features that supports the first RAN, detecting a second RAN not supported by the first set of modem features, and rebooting the modem software to load a second set of modem features that supports the detected RAN. For certain aspects, the first RAN may be a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) network and the second RAN may be a Wideband-Code Division Multiple Access (W-CDMA) network or Long-Term Evolution (LTE) network. This allows features to be loaded into memory (e.g., only) when they are required to support a detected RAN, rather than loading an entire image, thereby conserving DRAM and increasing efficiency.

Description

[0001] Claiming Priority Based on 35 U.S.C. §119 [0002] This application claims the benefit of US Provisional Patent Application Serial No. 61 / 735,827 filed December 11, 2012, which is hereby incorporated by reference in its entirety. technical field [0003] In general, certain aspects of the present disclosure relate to device configuration, and more specifically, certain aspects of the present disclosure relate to methods for updating a device configuration (e.g., based on a determination that a radio access technology (RAT) is not currently supported. ) to load the method and apparatus for supporting the feature set of the RAT). Background technique [0004] Devices evolve over time to support multiple configurations (eg, hardware and / or software configurations). Often, once a device is configured, it may not be easy to adapt to changes in the device's operating environment. [0005] Furthermore, wireless communication networks are widely deployed to provide various ...
