Abstract
A multi-mode controller (MMC) manages communications on a wireless device to provide interoperability between multiple radio access technologies (RATs) or radio access protocols.
Claims20
A device for wireless communication application using radio access protocols, the radio access protocols comprising a long-term evolution protocol, the radio access protocols further comprising a code division multiple access protocol, the device comprising:
- (a) an application processor to control wireless communication application on the device;
- (b) a long-term evolution stack for communication using the long-term evolution protocol;
- (c) a code division multiple access stack for communication using the code division multiple access protocol;
- and
- (d) a multi-mode controller, comprising:
- (d1) a multi-mode controller stack to manage inter radio access protocols operation between the long-term evolution protocol and the code division multiple access protocol, the multi-mode controller stack comprising:
- (d1A) a global mode system selection module to perform global system selection, the global system selection being based on a user input, the global system selection further being based on a network location, the global system selection further being based on a channel condition;
- (d1B) a measurement and reselection module to perform measurements on an inactive radio access protocol, the measurement and reselection module further to decide whether there should be a handoff from an active radio access protocol to the inactive radio access protocol, the inactive radio access protocol being one selected from the group consisting of the long-term evolution wireless protocol and the code division multiple access wireless protocol;
- (d1C) a packet data control module to handle packet service sessions;
- and
- (d1D) a circuit switch control module to handle circuit switch control;
- (d2) an application program interface to interface the multi-mode controller stack to the application processor;
- (d3) a long-term evolution application program interface to interface the multi-mode controller stack to the long-term evolution stack;
- and
- (d4) a code division multiple access application program interface to interface the multi-mode controller stack to the code division multiple access stack.
A device for wireless communication application, comprising:
- a multi-mode controller stack to manage communication using a first radio access protocol, the multi-mode controller stack to manage communication using a second radio access protocol;
- an application program interface to interface the multi-mode controller stack to the wireless communication application;
- a first application program interface to interface the multi-mode controller stack to a first radio access protocol stack;
- and
- a second application program interface to interface the multi-mode controller stack to a second radio access protocol stack.
A system for communicating using a first radio access technology, the system further for communicating using a second radio access protocol, the system comprising:
- a multi-mode controller to manage inter radio access protocol operation between the first radio access protocol and the second radio access protocol;
- a first application program interface to interface the multi-mode controller to a first radio access protocol stack;
- and
- a second application program interface to interface the multi-mode controller to the second radio access protocol stack.
