Abstract

A system and method facilitate modifying behavior of an application coupled to a device and a server based on bandwidth. The method determines a first bandwidth state. A change is then detected from the first bandwidth state to a second bandwidth state. Subsequently, the behavior of an application is changed based on bandwidth parameters of the second bandwidth state.

Claims

1. A wireless device having a central processing unit (CPU) and a plurality of modems, each said modem being for use in establishing a different type of wireless connection, in which the CPU is coupled to:

a connection manager configured to;

monitor use of the plurality of modems in order to determine whether the wireless device has a wireless connection with a wireless local area network (WLAN) or a mobile communication network, a wireless connection with the WLAN having a first bandwidth state associated therewith and a wireless connection with the mobile communication network having a second, different, bandwidth state associated therewith; and

in response to a change in the use of the plurality of modems, notify an application executing on the wireless device of the change;

wherein the application is configured to;

establish a communication operation with a server remote from the wireless device based on capabilities associated with whichever of the first or second bandwidth state has been determined for the wireless connection and at least one rule for use in controlling communication between the application and the server; and

in response to said notification, modify the communication operation on the basis of said change.

2. The system of claim 1, wherein the connection manager is configured to communicate data indicative of the determined first or second bandwidth state associated with the wireless connection to the application.

3. The system of claim 2, wherein the application is configured to modify the communication operation based on the determined first or second bandwidth state associated with the wireless connection.

4. The system of claim 3, wherein said modification comprises enabling synchronization of information between the wireless device and the server when the wireless connection is determined to be in the first bandwidth state.

5. The system of claim 3, wherein said modification comprises disabling synchronization of information between the wireless device and the server when the wireless connection is determined to be in the second bandwidth state.

6. A method for controlling communication between an application executing on a wireless device and a server remote from the wireless device, the wireless device comprising a plurality of modems for use in establishing a different type of wireless connection, the method comprising:

maintaining at least one rule for use in controlling communication between the application and the server;

monitoring use of the plurality of modems in order to determine whether the wireless device has a wireless connection with a wireless local area network (WLAN) or a mobile communication network, a wireless connection with the WLAN having a first bandwidth state associated therewith and a wireless connection with the mobile communication network having a second, different, bandwidth state associated therewith;

establishing a communication operation of the application executing on the wireless device based on capabilities associated with whichever of the first or second bandwidth state has been determined for the wireless connection and said at least one rule;

in response to a change in the use of the plurality of modems, notifying the application of the change; and

in response to said notification, causing the application to modify the communication operation on the basis of said change.

7. The method of claim 6 further comprising communicating data indicative of the determined first or second bandwidth state associated with the wireless connection to the application.

8. The method of claim 7 further comprising modifying the communication operation based on the determined first or second bandwidth state associated with the wireless connection.

9. The method of claim 8, wherein said modification comprises enabling synchronization of information between the wireless device and the server when the wireless connection is determined to be in the first bandwidth state.

10. The method of claim 8, wherein said modification comprises disabling synchronization of information between the wireless device and the server when the wireless connection is determined to be in the second bandwidth state.

11. A non-transitory machine-readable storage medium having stored thereon data representing sets of instructions which, when executed by a machine, cause the machine to:

monitor use of a plurality of modems associated with a wireless device, each said modem being for use in establishing a different type of wireless connection on the wireless device;

determine whether the wireless device has a wireless connection with a wireless local area network (WLAN) or a mobile communication network on the basis of the monitored use of the plurality of modems, a wireless connection with the WLAN having a first bandwidth state associated therewith and a wireless connection with the mobile communication network having a second, different, bandwidth state associated therewith;

establish a communication operation of an application executing on the wireless device and a server remote from the wireless device based on capabilities associated with whichever of the first or second bandwidth state has been determined for the wireless connection and at least one rule for use in controlling communication between the application and the server;

in response to a change in the use of the plurality of modems, notify an application on the wireless device of the change; and

in response to said notification, cause the application to modify the communication operation on the basis of said change.

12. The non-transitory machine-readable storage medium of claim 11, wherein the sets of instructions, when executed by the machine, further cause the machine to communicate data indicative of the determined first or second bandwidth state associated with the wireless connection to the application.

13. The non-transitory machine-readable storage medium of claim 12, wherein the sets of instructions, when executed by the machine, further cause the machine to modify the communication operation based on the determined first or second bandwidth state associated with the wireless connection.

14. The non-transitory machine-readable storage medium of claim 13, wherein said modification comprises enabling synchronization of information between the wireless device and the server when the wireless connection is determined to be in the first bandwidth state.

15. The non-transitory machine-readable storage medium of claim 13, wherein said modification comprises disabling synchronization of information between the wireless device and the server when the wireless connection is determined to be in the second bandwidth state.
