A multi-mode controller (MMC) manages communications on a wireless device to provide interoperability between multiple radio access technologies (RATs) or radio access protocols.

Apparatus and system for multi-mode wireless communication

An apparatus supporting MTC in an LTE environment including an LTE modem and a CDMA modem. The LTE modem accesses a first wireless network and executes first data transactions, where the first wireless network comports with LTE standards. The CDMA modem is operationally coupled to the LTE modem, and accesses a second wireless network and executes second data transactions, where the second wireless network comports with one or more CDMA-based standards. The CDMA modem includes an inter-radio access technology (IRAT) API element and an inter-process communication (IPC) module. The IRAT API element is configured to send/receive IRAT messages via function calls to/from the LTE modem, where the IRAT messages remain the same regardless of interface requirements for the LTE modem. The IPC module is coupled to the IRAT API element, and is configured to generalize the function calls to enable the CDMA modem to interoperate with the LTE modem.
