Abstract

A telecommunications system for receiving from a telecommunications unit a request for data from a target network address may include a request completion unit configured to receive the request for data from the telecommunications unit and to transmit a request for the data to the target address. The request completion unit may be further configured, on receiving the data from the target address, to transmit the data to the telecommunications unit via the radio link. The request completion unit, if it is determined that the request to the target address is not satisfied, may be configured to attempt to establish communication with the target address, and, if it is determined that such communication is possible, transmit an indication via the radio link to the telecommunications unit.

Claims

1. A telecommunications system for receiving from a telecommunications unit via a radio link a request for data from a target network address, the system comprising:

a request completion unit configured to receive the request for data from the telecommunications unit and to transmit a request for the data to the target address, and further configured, on receiving the data from the target address, to transmit the data to the telecommunications unit via said radio link;

and wherein the request completion unit, if it is determined that the request to the target address is not satisfied, is configured to;

i. attempt to establish communication with the target address, and

ii. if it is determined that such communication is possible transmit an indication via said radio link to the telecommunications unit.

2. A telecommunications system as claimed in claim 1, wherein said request completion unit is configured to attempt to establish communication by repeating the transmission of the request to the target address.

3. A telecommunications system as claimed in claim 2, wherein said request completion unit is configured such that determination that such communication is possible is made on receipt of the said data from the target address and transmitting the data to the telecommunications unit as said indication.

4. A telecommunications system as claimed in claim 1, wherein said request completion unit is configured such that attempting to establish communication comprises polling the target address to determine whether communication can be made with the target address.

5. A telecommunications system as claimed in claim 1, wherein an internet protocol link can be supported between the telecommunications unit and the target address.

6. A telecommunications system as claimed in claim 5, wherein an internet protocol link adapted for use over a radio link can be supported between the telecommunications system and the telecommunications unit.

7. A telecommunications system as claimed in claim 1, wherein the telecommunications unit is a mobile telephone.

8. A telecommunications system as claimed in claim 1, wherein the telecommunications unit is a cellular telecommunications system.

9. A telecommunications system as claimed in claim 1, wherein the data comprises hypertext transfer protocol data.

10. A telecommunications system as claimed in claim 1, wherein the target address is a universal resource locator address.

11. A telecommunications system as claimed in claim 1, wherein the request completion unit is configured to re-establish a connection with the telecommunications unit in order for the said indication to be carried to the telecommunications unit.

12. A telecommunications system as claimed in claim 1, wherein the said indication is sent by means of a data push facility.

13. A telecommunications system as claimed in claim 1, wherein the telecommunications unit is capable of alerting a user of the telecommunications unit that the said data is available.

14. A method for operating a radio telecommunications network, comprising:

receiving by radio from a telecommunications unit a request for data from a target network address at a unit intermediate said telecommunications unit and said target address;

transmitting a request for the data to the target address;

on receiving the data from the target address, transmitting the data to the telecommunications unit; and

at said intermediate unit, if it is determined that the request to the target address is not satisfied;

i. attempting to establish communication with the target address, and

ii. if it is determined that such communication is possible transmitting an indication to the telecommunications unit.

15. A request completion unit comprising:

a receiver configured to receive a request for data from a target network address, said request being received from a telecommunications unit via a radio link;

a transmitter configured, on receiving the data from the target address to transmit the data to the telecommunications unit via said radio link; and

a processor configured to;

i. attempt to establish communication with the target address, and

ii. if it is determined that such communication is possible to cause the transmitter to transmit an indication via said radio link to the telecommunications unit.

16. A unit as claimed in claim 15, wherein an internet protocol link can be supported between the telecommunications unit and the target address.

17. A unit as claimed in claim 15, wherein the data comprises hypertext transfer protocol data.

18. A unit as claimed in claim 15, wherein the target address is a universal resource locator address.

19. A unit as claimed in claim 15, wherein the processor is configured to cause re-establishing of a connection with the telecommunications unit in order for the said indication to be carried to the telecommunications unit.

20. A unit as claimed in claim 15, wherein the said indication is sent by means of a data push facility.

21. A request completion unit as claimed in claim 15, said unit being incorporated in a network unit.

22. A request completion unit comprising:

receiving means for receiving a request for data from a target network address, said request being received from a telecommunications unit via a radio link;

transmitting means for, on receiving the data from the target address, transmitting the data to the telecommunications unit via said radio link; and

processing means for, if it is determined that the request to the target address is not satisfied,

i. attempting to establish communication with the target address; and

ii. if it is determined that the communication as possible causing said transmitting means to transmit an indication via the radio link to the telecommunications unit.

23. A telecommunications system comprising:

a telecommunications unit configured to send a request for data from a target network address, via a radio link; and

a request completion unit comprising;

a receiver configured to receive said request via said radio link;

a transmitter configured, on receiving the data from the target address to transmit the data to the telecommunications unit via said radio link; and

a processor configured, if it is determined that the request to the target address is not satisfied, to;

i. attempt to establish communication with the target address, and

ii. if it is determined that such communication is possible cause said transmitter to transmit an indication via said radio link to said telecommunications unit.

24. A telecommunications system comprising:

request means for receiving, via a radio link, a request for data from a target network address, said request being received from a telecommunications unit and for transmitting a request for the data to the target address; and

response means for, on receiving the data from the target address, transmitting the data to the telecommunications unit via said radio link and wherein the request means comprises completion means for if it is determined that the request to the target address is not satisfied,

i. attempting to establish communication with the target address, and

ii. if it is determined that such communication is possible transmitting an indication via said radio link to said telecommunications unit.

25. A computer readable medium having computer executable components encoded therein comprising:

a first computer executable component configured to cause a request completion unit to receive via a radio link from a telecommunications unit a request for data from a target network address;

a second computer executable component configured when loaded in said request completion unit to transmit a request for data to the target address; and

a third computer executable component configured, on receiving the data from the target address to cause the data to be transmitted to the telecommunications unit, and if it is determined that the request to the target address is not satisfied to

i. attempt to establish communication with the target address, and
