Abstract

A system for managing the activity of one or more of concurrently active wireless communication mediums being supported by at least one radio module integrated within a wireless communication device. More specifically, the present invention, in at least one embodiment, may align communication controlled by Internet protocol (EP) with operational schedules formulated for supporting wireless communication mediums and/or radio modules.

Claims

1. A method, comprising:

receiving information regarding one or more wireless communication mediums supported by at least one radio module in a wireless communication device;

formulating an operational schedule for the at least one radio module;

determining at least one wireless communication medium being used for communicating Internet protocol information from the one or more wireless communication mediums; and

adjusting maximum transfer packet size for the internet protocol communication based on at least the operational schedule for the at least one radio module supporting the at least one wireless communication medium communicating Internet protocol information.

25. A method according to claim 1, wherein the information regarding one or more wireless communication mediums includes at least one of a number of pending messages, an age of pending messages, a priority of pending messages and error rate information.

26. A method according to claim 1, wherein formulating a schedule for the at least one radio module includes assigning one or more time periods during which operation is permitted to the one or more of the wireless communication mediums.

27. A method according to claim 1, wherein adjusting the maximum transfer packet size includes adjusting the maximum transfer packet size on at least one of sent and received packets.

28. A method according to claim 27, wherein the maximum transfer packet size of a sent packet is adjusted by setting a size control variable in the Internet protocol stack.

29. A method according to claim 27, wherein the received package size is controlled by sending a wireless alert message to another device sending the Internet protocol packet to the wireless communication device.

30. A method according to claim 29, wherein the wireless alert message informs the other device to reduce the size of the Internet protocol packet.

31. A method according to claim 29, wherein the wireless alert message is sent to the other device before any Internet protocol packets have been received at the wireless communication device.

32. A method according to claim 29, wherein the wireless alert message is sent to the other device in response of not successfully receiving one or more Internet protocol packets from the another device.

2-24. -24. (canceled)

33. A computer program product comprising a computer usable medium having computer readable program code embodied in said medium, comprising:

a computer readable program code configured to receive information regarding one or more wireless communication mediums supported by at least one radio module in a wireless communication device;

a computer readable program code configured to determine at least one wireless communication medium being used for communicating Internet protocol information from the one or more wireless communication mediums; and

a computer readable program code configured to adjust maximum transfer packet size for the internet protocol communication based on at least the operational schedule for the at least one radio module supporting the at least one wireless communication medium communicating Internet protocol information.

34. A computer program product according to claim 33, wherein the information regarding one or more wireless communication mediums includes at least one of a number of pending messages, an age of pending messages, a priority of pending messages and error rate information.

35. A computer program product according to claim 33, wherein formulating a schedule for the at least one radio module includes assigning one or more time periods during which operation is permitted to the one or more of the wireless communication mediums.

36. A computer program product according to claim 33, wherein adjusting the maximum transfer packet size includes adjusting the maximum transfer packet size on at least one of sent and received packets.

37. A computer program product according to claim 33, wherein the maximum transfer packet size of a sent packet is adjusted by setting a size control variable in the Internet protocol stack.

38. A computer program product according to claim 33, wherein the received package size is controlled by sending a wireless alert message to another device sending the Internet protocol packet to the wireless communication device.

39. A computer program product according to claim 38, wherein the wireless alert message informs the other device to reduce the size of the Internet protocol packet.

40. A computer program product according to claim 38, wherein the wireless alert message is sent to the other device before any Internet protocol packets have been received at the wireless communication device.

41. A computer program product according to claim 38, wherein the wireless alert message is sent to the other device in response of not successfully receiving one or more Internet protocol packets from the another device.

42. A device comprising:
