Abstract: A communication device using a current wireless network via a first access point confirms availability of a second access point before breaking the current connection. To confirm availability of the second access point, the communication device sends a power management message that causes the first access point to store packets during the power management period. After the connection to the second access point is confirmed, the second session may be put on hold using the same technique while the connection to the first access point is restored, the stored packets processed and the connection closed. Then the connection to the second access point may be reactivated and further communication made through the second access point.

Abstract: The present disclosure describes methods and apparatuses for implementing virtual dynamic library loading in embedded systems. In some aspects, a determination is made that a feature is not available in firmware executed from a first memory. Based on information associated with the feature, a portion of a second memory is allocated for code of the feature. In some cases, the portion of the second memory is allocated from a data buffer or part of a shared memory. The code of the feature is loaded to the allocated portion of the second memory and address aliasing logic is configured enable execution of the feature from the second memory. By allocating and executing firmware features from the second memory, a size of the firmware executed from the first memory can be reduced to conserve memory space and other firmware features may be dynamically loaded and executed from the second memory.
