Abstract

Aggregating multiple modems in a communication device into a radio-frequency-link aggregation group increases the limited data bandwidth of RF data transmission between a communication device and its operator network. An aggregation controller in the communication device monitors the availability of its modems and selects modems to be used in a radio-frequency-link aggregation group. The aggregation controller also selects an aggregation algorithm. A radio-frequency-link aggregation module in the communication device distributes data to modems in the radio-frequency-link aggregation group in accordance with the aggregation algorithm. A connectivity service in the communication device notifies the operator network of the modems in the radio-frequency-link aggregation group and acknowledges that the operator network agrees to handle transmission from the radio-frequency-link aggregation group.

Claims

1. A communication device comprising:

at least two modems,

an application processor configured to distribute data from an application residing on the communication device to said at least two modems for RF transmission;

an aggregation controller configured to select from the at least two modems to form a set of selected modems for a radio-frequency-link aggregation group;

a connectivity module configured to

send, to an operator network, subscription information and modem identifiers for the selected modems in the radio-frequency-link aggregation group, wherein the subscription information enables the operator network to bill an account associated with the selected modems;

monitor availability of the at least two modems for the radio-frequency-link aggregation group; and

acknowledge that the operator network, connected to radio frequency links of the radio-frequency-link aggregation group, has agreed to handle aggregated data from the radio-frequency-link aggregation group; and

an aggregation module configured to receive data from the application and distribute data to the selected modems in accordance with an aggregation algorithm; and

wherein said selected modems are configured to send distributed data received from the application processor over a radio frequency link to a radio frequency node in the operator network.

2. The communication device of claim 1 further comprising:

a load balancing module configured to analyze, responsive to the aggregation algorithm, a transmission capacity of the selected modems and distribute the data from the application according to the aggregation algorithm and the transmission capacity of the selected modems.

3. The communication device of claim 2 wherein the aggregation algorithm is based on a type of application or a type of data being transmitted.

4. A communication device comprising:

a plurality of modems;

an aggregation controller means for selecting an aggregation algorithm and a set of selected modems for a radio-frequency-link aggregation group, the set of selected modems selected from the plurality of modems;

means for monitoring availability of each of the plurality of modems for the radio-frequency-link aggregation group;

means for acknowledging that an operator network, connected to radio frequency links of the radio-frequency-link aggregation group, has agreed to handle aggregated data from the radio-frequency-link aggregation group;

connectivity means for sending, to an operator network, subscription information and modem identifiers of the modems in the radio-frequency-link aggregation group from the communication device, wherein the subscription information enables the operator network to bill an account associated with the selected modems; and

an aggregation means, responsive to the aggregation controller means, for distributing data that is received from an application to the selected modems selected by the aggregation controller means whereby a data transmission rate from the communication device is increased.

5. The communication device of claim 4 wherein said aggregation means comprises:

a load balancing means for analyzing the transmission capacity of the selected modems and distributing the data from the application according to the selected aggregation algorithm and the transmission capacity of the selected modems.

6. The communication device of claim 5 wherein the aggregation algorithm is based on a type of the application providing the data for transmission or the type of data being transmitted.

7. The communication device of claim 4 wherein the subscription information sent by said connectivity means has one subscription identifier that is the same for all of the selected modems.

8. The communication device of claim 4 wherein the subscription information sent by said connectivity means has a different subscription identifier for each of the selected modems and one account number for the communication device.

9. A method for aggregating multiple modems of a communication device into a radio-frequency-link aggregation group to increase the bandwidth of the radio frequency data transmission from the communication device, said method comprising:

selecting an aggregation algorithm and a set of selected modems from the multiple modems to make up the radio-frequency-link aggregation group;

sending, to an operator network, subscription information, modem identifiers, and radio-frequency-link information for the selected modems from the communication device wherein the subscription information enables the operator network to bill an account associated with the selected modems;

distributing data, received from an application program, to the selected modems for data transmission from the communication device whereby the data transmission rate from the communication device is increased; and

detecting a radio frequency link failure at a failed modem in the set of selected modems;

said selecting includes removing the failed modem from the set of selected modems and choosing a new set of selected modems; and

resending modem identifiers corresponding to the new set of selected modems.

11. The method of claim 10 wherein distributing data includes:

distributing data to each of the selected modems in the radio-frequency-link aggregation group based on the aggregation algorithm selected.

12. The method of claim 9 wherein subscription information for the selected modems includes a subscription identifier and all of the selected modems have a same subscription identifier.

13. The method of claim 9 wherein subscription information for the selected modems includes a subscription identifier and each of the selected modems has a different subscription identifier.

14. A non-transitory, tangible computer readable storage medium, encoded with processor readable instructions to perform a method for aggregating multiple modems of a communication device into a radio-frequency-link aggregation group, said method comprising:

selecting an aggregation algorithm and a set of selected modems from the multiple modems to make up the radio-frequency-link aggregation group;

sending, to an operator network, subscription information, modem identifiers, and radio-frequency-link information for the selected modems from the communication device wherein the subscription information enables the operator network to bill an account associated with the selected modems;
