    • Aspects of a method and system for dynamically programmable serial/parallel bus interface may include performing in a first communication device coupled to a communication bus, attaching communication protocol information to a data signal for each data transaction with one or more other communication devices communicatively coupled to the communication bus. The one or more other communication devices may be controlled utilizing the attached communication protocol information. The communication protocol information may be dynamically adjusted and/or adaptively adjusted. The communication bus may be a serial or parallel communication bus. The serial communication bus may be a two-wire, three-wire, or four-wire bus. The attached communication protocol information comprises a multi-wire protocol, a 3-wire protocol, a Serial Peripheral Interface (SPI) protocol, a System Power Management Interface (SPMI), or an RF Bus protocol.

    • A method and system for providing improved wireless number portability. This invention allows the mobile switching center (MSC) to use a separate database to store the number portability information gathered earlier through sending NPreq messages to the number portability database (NPDB) and various strategies for refreshing or updating the internal database. The invention enables the MSC to use the separate database to check whether a portable number is ported and what the associated location routing number (LRN) if it is ported, so that the MSC does not need to send NPreq messages to the NPDB many times for the same ported number. This invention may apply to any number of switching systems, including CDMA, GSM and UMTS mobile switching systems.
