发明名称 Apparatus and method for internetworking interface in multimode wireless communication
摘要 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.

主权项 1. An apparatus, comprising: an LTE modem, configured to access a first wireless network, wherein said first wireless network comports with LTE radio access technology (RAT) standards; and a code division multiple access (CDMA) modem, operationally coupled to said LTE modem, coupled to and configured to access a second wireless network, wherein said second wireless network comports with one or more CDMA-based RAT standards, said CDMA modem comprising: an inter-radio access technology application programming interface element, configured to send/receive a plurality of IRAT messages via a plurality of function calls to/from said LTE modem, wherein said IRAT messages are compatible with said first wireless network and an interface requirement for said LTE modem, and wherein said plurality of function calls comprises system acquisition for said second wireless network, second wireless network data stack management, first wireless network system handoff, and connection management, and wherein one of said plurality of function calls comprises a request initiated from said LTE modem to request operations only over a CDMA network, and wherein said request directs operation of both circuit voice service and packet service over said CDMA network; and an inter-process communication module, coupled to said IRAT API element, configured to generalize said plurality of function calls to enable said CDMA modem to interoperate with said LTE modem, wherein said inter-process communication module is coupled to said LTE modem through an application processor.
