Abstract

A method and intermediate network node provide a service requested by a mobile terminal in a wireless communications network. The intermediate network node has a processing unit and a memory containing instructions executable by the processing unit. The intermediate network node receives a first request for a service from the mobile terminal, and receives application software configured to be executed at the intermediate network node to provide the mobile terminal with at least part of the requested service. The intermediate network node provides the mobile terminal with the at least part of the requested service. A subsequent request related to the service of the mobile terminal terminates at the intermediate network node, and provides the mobile terminal with at least part of the service requested in the subsequent request on behalf of a provider of the service.

Claims

1. A method of a network node of a Radio Access Network of providing a service to a mobile terminal in a wireless communications network, the method comprising:

receiving a first request for the service from the mobile terminal;

in response to the first request received from the mobile terminal, communicating with a server providing the requested service;

receiving an application software from the server providing the requested service, the application software configured to be executed at the network node to provide the mobile terminal with at least part of the requested service, wherein the application software is provided by the server responsive to the communicating;

providing the mobile terminal with said at least part of the requested service by executing the application software at the network node responsive to the first request;

receiving a second request related to the service from the mobile terminal wherein the second request is subsequent to the first request; and

providing, from the network node, the mobile terminal with at least part of the service requested in said second request on behalf of a provider of said service by executing the application software at the network node, wherein the second request terminates at the network node.

2. The method according to claim 1, wherein the step of communicating with the server further comprises:

submitting to the server an identifier of the network node.

3. The method according to claim 1, further comprising:

preloading, at the network node, data associated with the requested service.

4. The method according to claim 3, wherein the step of providing the mobile terminal with the at least part of the service requested comprises:

providing the mobile terminal with the preloaded data.

5. The method according to claim 1, further comprising:

receiving, at the network node, instructions on how to generate data associated with the requested service locally at the network node to be supplied to the mobile terminal.

6. The method according to claim 5, wherein the instructions on how to generate data is received from the server.

7. The method according to claim 5, wherein the instructions on how to generate data are received from the mobile terminal.

8. The method according to claim 5, wherein the step of providing the mobile terminal with the requested service comprises:

providing the mobile terminal with the locally generated data.

9. The method according to claim 3, further comprising:

receiving, at the network node, instructions on how to obtain the data associated with the requested service at the network node.

10. The method according to claim 1, further comprising:

determining what data the mobile terminal is likely to request in said subsequent request; and

preloading or locally generating the data which is most likely to be requested in said subsequent request.

11. The method according to claim 1, further comprising:

detecting whether a handover of the mobile terminal is to be made to another network node of the Radio Access network; and

transferring the application software, and any preloaded data or any locally generated data to said another network node.

12. The method according to claim 1, further comprising:

acquiring, at the network node, a position of the mobile terminal; and

adapting the requested data provided to the mobile terminal on the basis of the acquired position of the mobile terminal.

13. The method according to claim 1, further comprising:

receiving from the mobile terminal an indication that no further requests for the service will be made; and

uninstalling the application software in response to the received indication that no further requests will be made.

14. The method according to claim 1, further comprising:

receiving a request for the service from a further mobile terminal;

providing, by executing the application software, the further mobile terminal with at least part of the service requested on behalf of the provider of the service.

15. The method of claim 1 wherein the network node is a network base station node of the Radio Access Network.

16. The method of claim 11 wherein said network node and said another network node are network base station nodes.

17. A network node of a Radio Access Network for providing a service to a mobile terminal, comprising a processing unit and a memory, said memory containing instructions executable by said processing unit, whereby said network node is configured to perform operations to:

receive a first request for the service from the mobile terminal;

communicate with a server providing the service in response to the request received from the mobile terminal;

receive application software from the server providing the requested service, the application software configured to be executed at the network node to provide the mobile terminal with at least part of the requested service, wherein the application software is provided by the server responsive to the communicating;

provide the mobile terminal with said at least part of the requested service by executing the application software responsive to the first request;

receiving a second request related to the service from the mobile terminal wherein the second request is subsequent to the first request; and

provide the mobile terminal with at least part of the service requested in said second request on behalf of a provider of said service by executing the application software, wherein the second request terminates at the network node.

18. The network node of claim 17 wherein the network node and said another network node are network base station nodes.

19. The network node according to claim 18, further configured to:

submit to the server an identifier of the node.

20. The network node according to claim 18, further configured to:

preload data associated with the requested service.

21. The network node according to claim 20, further configured to:

provide the mobile terminal with the preloaded data.

22. The network node according to claim 18, further configured to:

receive instructions on how to generate data associated with the requested service locally at the network node to be supplied to the mobile terminal.

23. The network node according to claim 22, wherein the instructions on how to generate data are received from the server.

24. The network node according to claim 22, wherein the instructions on how to generate data are received from the mobile terminal.

25. The network node according to claim 22, further configured to:

provide the mobile terminal with the locally generated data.

26. The network node according to claim 20, further configured to:

receive instructions on how to obtain the data associated with the requested service.

27. The network node according to claim 18, further configured to:

determine what data the mobile terminal is likely to request in said subsequent request; and

preload or locally generate the data which is most likely to be requested in said subsequent request.

28. The network node according to claim 18, further configured to:
