Abstract

A method of co-ordinating the time of execution of a plurality of applications all hosted by the same communications device, each application requiring a network connection for completion of a predetermined task, the method comprising for each task: determining one or more task completion conditions including one or more network conditions for said network connection required to complete said task; retrieving stored data indicating for a predetermined period of time, one or more network characteristics for an available network connection; processing said task completion conditions to determine if said one or more network characteristics retrieved for said predetermined period of time match said one or more network conditions for said network connection required to complete said task; and in the event of a match in between the network characteristics of a connection available for a predetermined period of time and the network conditions required for said network connection to complete said task, scheduling said task for execution in said predetermined period of time; and reducing the predetermined period of time by the duration of the network connection required to complete a scheduled task.

Claims

1-39. -39. (canceled)

40. A method of scheduling a data transmission over a wireless network connection in a communications network, said data transmission being required for completion of one or more predetermined tasks by an application hosted on a communications device in said communications network, the method comprising, for each task using at least one computer to:

(a) determine one or more conditions required for said data transmission to enable said application to complete said task;

(b) determine one or more network conditions required for said wireless network connection to support said data transmission and enable said application to complete said task;

(c) predict when said one or more network conditions in said communications network will meet the requirements imposed by the one or more conditions for said data transmission to complete said task by;

retrieving stored data indicating timing information for said one or more network characteristics for an available network connection; and

processing said timing information to predict when said one or more network conditions for said network connection required to complete said task match said task completion conditions; and

(d) scheduling said data transmission in accordance with the predicted one or more network conditions.

41. A method as in claim 40, wherein said prediction of said one or more network conditions is automatically performed when an application is configured to perform a task requiring repeated data transmission.

42. A method as in claim 40, wherein said timing information comprises a duration of said network conditions above one or more threshold criteria.

43. A method as in claim 40, wherein said timing information comprises a duration of said network conditions above one or more threshold criteria, and one said threshold criterion comprises a predetermined period of time.

44. A method as in claim 40, wherein said stored data comprises data aggregated from a plurality of network connections established by a plurality of said communications devices.

45. A method as in claim 40, wherein said stored data comprises data aggregated from a plurality of network connections established by a plurality of said communications devices and wherein said aggregated data is derived from data in a shared memory store, said data being contributed to said shared memory store by a plurality of said communications devices in said communications network.

46. A method in claim 40, wherein the shared memory is accessible by a plurality of mobile communications devices in said communications network.

47. A method as claimed in claim 40, wherein the network characteristics of each connection available to said mobile communications device is stored in a shared memory populated using data derived from network connections established by a plurality of said communications devices in said communications network, and wherein the method further comprises:

passing data from said shared memory to the communications device hosting the application performing the predetermined task, whereby said prediction of said one or more network conditions is performed by the mobile communications device.

48. A method as in claim 40, wherein the shared memory is accessible by a plurality of mobile communications devices in said communications network, and the method further comprises:

using a network server aggregate the data stored in said shared memory in accordance with one or more predetermined conditions for aggregation;

passing said aggregated data to the communications device hosting the application performing the predetermined task;

processing said aggregated data on the mobile communications device to automatically predict when network conditions are available for completion of said task.

49. A method as in claim 40 wherein the shared memory is accessible by a plurality of mobile communications devices in said communications network and the method further comprises:

using a network to server aggregate the data stored in said shared memory in accordance with one or more predetermined conditions for aggregation;

said server processing said aggregated data to predict said timing information for said one or more network conditions; and

said server passing said predicted timing information to the communications device hosting the application performing the predetermined task;

wherein the mobile communications device determines from said passed predicted timing information when to schedule said task on an available network connection.

50. A communications device comprising components arranged to implement the method of claim 40.

51. A network server comprising:

a data aggregator arranged to aggregate network characteristics of connections established with a plurality of communication devices in a communications network;

one or more data processors arranged to populate a shared memory with said aggregated network characteristics for said connection associated with predetermined periods of time, the data being arranged to be provided to a forecasting component arranged to predicting when one or more network conditions in said communications network will meet one or more requirements imposed by one or more conditions for data transmission by a mobile communications device operating in said communications network to complete a task by;

retrieving stored data indicating timing information for said one or more network characteristics for an available network connection; and

processing said timing information to predict when said one or more network conditions for said network connection required to complete said task match said task completion conditions.

52. A communications system comprising a plurality of communications devices each communications device being arranged to co-ordinate the time of execution of a plurality of applications supported by said respective communications device each application requiring a network connection for completion of a predetermined task, wherein each communications device comprises:

means to determine one or more task completion conditions including one or more network conditions for said network connection required to complete said task;
