Abstract

Re-establishing a transmission of data from a first station to a second station involves pausing transmission of data from a first station to a second station following an indication that a communication session is inactive. The first station receives an indication to the effect that the inactive session has been reestablished and that data is to be transmitted then sends only a portion of data that has not been sent.

Claims

1. A method of re-establishing a transmission of data from a first station to a second station, comprising the steps of

pausing transmission of data from said first station to said second station following an indication that a communication session is inactive;

receiving an indication to the effect that the inactive session has been reestablished and that data is to be transmitted;

sending, from said first station to said second station, only a portion of data that has not been sent during said pause in transmission.

2. A method according to claim 1, wherein said indication that said communication session is inactive is provided by receiving an indication from said second station to the effect that the communication session is inactive but still operational.

3. A method according to claim 1, wherein said indication that said communication session is inactive is provided by non-receipt at said first station of an anticipated transmission.

4. A method according to any of claims 1 to 3, wherein said transmitted data consists of transactional data and streamed data;

and

said step of sending a portion of said data comprises the steps of;

sending all transactional data that has not been already sent;

sending streamed data that has not been superseded by other streamed data.

5. A method according to claim 4, wherein said step of sending a portion of said data further comprises the step of:

amalgamating at least two messages of streamed data into a single streamed message.

6. A server for transmitting data packets to at least one terminal, wherein said server is configured to reestablish a transmission to a terminal, comprising the steps of

pausing transmission of data from the server to a terminal following an indication that a communication session is inactive;

receiving an indication to the effect that the inactive session has been reestablished and that data is to be transmitted; and

sending to said terminal only a portion of the data that has not been sent during said paused transmission.

7. A server according to claim 6, wherein said indication that said communication session is inactive is provided by receiving an indication from said terminal to the effect that the communication session is inactive but still operational.

8. A server according to claim 6, wherein said indication that said communication session is inactive is provided by non-receipt at said server of an anticipated transmission.

9. A server according to claim 6, wherein said transmitted data consists of transactional data and streamed data and said server is configured to send said data by

sending all transactional data that has not been already sent;

and

sending streamed data that has not been superseded by other streamed data.

10. A server according to claim 9, wherein said server is configured to send a portion of said data by amalgamating at least two messages of streamed data into a single streamed message.

11. A server according to claim 6, configured to transmit data packets to a plurality of terminals.

12. A server according to claim 6 configured to communicate with a terminal embodied as a mobile terminal or radio device.

13. Instructions executable by a network of computers and/or programmable data processing devices such that when executing said instructions stations connected to said network will transmit data packets over said network and said network will perform the steps of

pausing transmission of data from a first station to a second terminal following an indication that a communication session is inactive;

receiving at said first station an indication to the effect that the inactive session has been reestablished and that data is to be transmitted to said second station; and

sending from said first station to said second station only a portion of the data that has not been sent during said pause in transmission.

14. Instructions executable by a combination of a server and mobile terminal connected to said server by a radio network such that when executing and instructions said combination performs the steps of

pausing transmission of data from said server to a terminal following an indication that a communication session is inactive;

receiving at said server an indication to the effect that the inactive session has been reestablished and that data is to be transmitted to said terminal; and

sending from said server to said terminal only a portion of the data that has not been sent during said pause in transmission.

15. A computer readable medium having computer readable instructions executable by a computer such that when executing said instructions a computer will perform the steps of

pausing the transmission of data to a networked device following an indication that a communication session is inactive;

receiving an indication to the effect that the inactive session has been reestablished and that data is to be transmitted; and

sending to said previously inactive networked device only a portion of the data that has not been sent during said pause in transmission.

16. A computer readable medium having computer readable instructions according to claim 15 such that when executing said instructions a computer will perform the step of receiving an indication from a networked device to the effect that the communication session is inactive but still operational.

17. A computer readable medium having computer readable instructions according to claim 15 such that when executing said instructions a computer will perform the step of identifying the non-receipt of an anticipated transmission indicating that a communication session is active.

18. A computer readable medium having computer readable instructions according to claim 15 such that when executing said instructions a computer will perform the step of sending a portion of said data by

sending all transactional data that has not been already sent;

and

sending streamed data that has not been superseded by other streamed data.
