Abstract

Embodiments of the invention provide the ability to use policy defined by the operator to control the interfaces on which data is sent and received by a device. The policy can be dynamically updated by the operator, by pushing new policy to the device for implementation. The policy can define that the device should switch certain data between two or more available interfaces at certain times, or may define when certain data may be sent or received over a particular interface. Advantageously, the device may receive new policy from the operator in order to help with the operator'"'"'s own operational objectives. For example, the operator may be engaging in traffic shaping or other traffic limitation, for example to ease congestion or enforce service agreements.

Claims

1. A method of traffic shaping in a mobile communications network, comprising:

determining that a traffic shaping condition is met; and

in response to the determination, initiating traffic shaping measures;

characterised in that the traffic shaping measures comprise;

sending a configuration update to a mobile device wirelessly connected to the mobile communications network via a first physical networked interface, the configuration update comprising a policy generating entity defined policy that indicates, to the mobile device, one or more data transfer adaptation rules including one or more data characteristics, the data characteristics relating to data the transfer of which through the first physical networked interface is to be adapted.

2. A method according to claim 1, wherein the data characteristics relate to data that is to be transferred from the mobile device via a second physical networked interface on the device.

3. A method according to claim 1, wherein the data characteristics relate to data that is to be blocked from being transferred through the first physical interface to the mobile communications network.

4. A method according to claim 3 wherein the data characteristics define one or more of:

i) a particular type of data;

ii) a period of time for which the transfer of data is to be adapted;

iii) a location at which the transfer of data is to be adapted; and

iv) data associated with a particular application that requests or generates data.

5. A method according to claim 1 wherein the policy generating entity is a service provider running a server with which the mobile device interacts by transmitting data relating to a service, and a service provider defined policy is transmitted from the server to the mobile device as the policy generating entity defined policy when the service provider wishes to vary characteristics of the data transferred from the mobile device to the server.

6. A method according to claim 1 wherein the policy generating entity is a network operator, and a network operator defined policy is transmitted from the network operator as the policy generating entity defined policy when the network operator is engaging in traffic shaping or other traffic limitation measures, the policy defining data characteristics of data traffic that the network operator wishes to limit.

7. A method according to claim 6 wherein the data traffic that is limited includes traffic control data, and traffic relating to the data that the device may otherwise have tried to access.

8. A method according to claim 6 wherein the network operator defined policy is transmitted dynamically to the mobile device so as to support operational objectives of the network operator at a defined period of time.

9. A method according to claim 1, wherein the policy generating entity defined policy is an XML file comprising policy condition definitions and policy action definitions.

10. A method according to claim 2, wherein the first physical networked interface comprises a cellular interface and the second physical networked interface comprises a wireless communication interface in accordance with a wireless communications standard.

11. A method according to claim 10, wherein the wireless communication interface comprises a WIFI interface.

12. A method according to claim 2 wherein the data transfer through the second networked interface is in addition to the data transfer through the first physical networked interface.

13. A method according to claim 2 wherein the data characteristics include a criterion to determine whether to initiate a connection using the second physical networked interface, the criterion include at least one of energy requirement to transmit or receive, expected duration of transmission or reception, and quality of service.

14. A method according to claim 1 wherein the defined policy specifies that the mobile device can allow message traffic to be transmitted but that prevents transfer of attachment data.
