Abstract

Embodiments comprise measures, including methods, apparatus and computer program products, for use in access network selection in a telecommunications system. The telecommunications system comprises, at least, a mobile telephony radio access network. At one or more network nodes of the mobile telephony radio access network a preference, to offload at least some data communication in the mobile telephony radio access network to a further radio access network other than the mobile telephony radio access network, is identified. In response to this identification, an indication of the identified offloading preference is caused to be transmitted, via the mobile telephony radio access network, to at least one user equipment.

Claims

1. A method for use in access network selection in a telecommunications system comprising at least a mobile telephony radio access network, the method comprising:

monitoring, by circuitry of a network node of the mobile telephony radio access network, a traffic volume within the mobile telephony radio access network;

determining, by the circuitry, whether the traffic volume exceeds a predetermined threshold;

identifying, by the circuitry and based on the determining, a preference to offload specific internet protocol (IP) flows of data communication in the mobile telephony radio access network to an available local area network;

transmitting, by the circuitry to a user equipment via the mobile telephony radio access network, an indication of the identified preference, the indication including at least one condition that, when satisfied, the user equipment is to offload the data communication; and

offloading, by the user equipment when the at least one condition is satisfied, the specific IP flows of the data communication without offloading other IP flows of the data communication.

2. The method according to claim 1, wherein said data communication further comprises any of:

a bearer between said user equipment and said mobile telephony radio access network,

a packet data network (PDN) connection between said user equipment and said mobile telephony radio access network, and

communication associated with at least a first public land mobile network (PLMN).

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

determining, by the circuitry, a prioritization of at least a first part of the data communication in the mobile telephony radio access network for offloading over at least a second part of the data communication in the mobile telephony radio access network, wherein

the identifying of the preference is based on the prioritization.

4. The method according to claim 3, wherein the prioritization is at least one of:

indicative of an authorization of said at least first part to be offloaded;

indicative of a prohibition on said at least second part being offloaded; and

based at least in part on an identity of the user equipment.

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

receiving, by the circuitry, an offload interest notification from the user equipment, wherein

the circuitry transmits the indication in response to receipt of the offload interest notification.

6. The method according to claim 5, wherein said indication comprises a single bit indication in a System Information Block (SIB) Information Element (IE).

7. The method according to claim 1, wherein when the at least one condition is satisfied, the user equipment initiates a process to offload the data communication to the available local area network.

8. The method according to claim 1, wherein

the data communication corresponds to a particular data radio bearer, and

the method further comprises authorizing, by the circuitry, the particular data radio bearer for data offloading.

9. An apparatus for use in access network selection in a telecommunications system comprising at least a mobile telephony radio access network, the apparatus configured for use in a network node of the mobile telephony radio access network, the apparatus comprising:

circuitry configured to

monitor a traffic volume within the mobile telephony radio access network;

determine whether the traffic volume exceeds a predetermined threshold;

identify, based on whether the traffic volume exceeds the predetermined threshold, a preference to offload specific internee protocol (IP) flows of data communication in the mobile telephony radio access network to an available local area network; and

transmit, to a user equipment via the mobile telephony radio access network, an indication of the identified preference, the indication including at least one condition that, when satisfied, the user equipment is to offload the data communication, wherein

the user equipment offloads, when the at least one condition is satisfied, the specific IP flows of the data communication without offloading other IP flows of the data communication.

10. The apparatus according to claim 9, wherein the network node comprises one or more of the following:

a base station,

a node B,

an evolved node B,

an access point,

a radio network controller, and

a base station controller.

11. An apparatus for use in access network selection in a telecommunications system comprising at least a mobile telephony radio access network, the apparatus configured for use in a user equipment within the mobile telephony radio access network, the apparatus comprising:

circuitry configured to receive, from a network node of the mobile telephony radio access network, an indication of an identified preference to offload specific Internet protocol (IP) flows of data communication in the mobile telephony radio access network to an available local area network, wherein

the network node monitors a traffic volume within the mobile telephony radio access network and determines whether the traffic volume exceeds a predetermined threshold,

the indication of the identified preference is identified by the network node based on whether the traffic volume exceeds the predetermined threshold,

the indication includes at least one condition that, when satisfied, the user equipment is to offload the data communication, and

the circuit is further configured to offload, when the at least one condition is satisfied, the specific IP flows of the data communication without offloading other IP flows of the data communication.

12. The apparatus according to claim 11, wherein the circuitry is configured to, in response to receipt of said indication, offload at least a part of the data communication from the mobile telephony radio access network to the available local area network.

13. The apparatus according to claim 11, wherein the circuitry is configured to:

determine a prioritization of at least a first part of the data communication in the mobile telephony radio access network for offloading over at least a second part of the data communication in the mobile telephony radio access network; and

transmit the prioritization to the network node.

14. The apparatus according to claim 11, wherein the circuitry is further configured to:

receive an offload interest query from the network node;

transmit an offload interest notification to the network node in response to the offload interest query;

detect said available local area network; and

transmit the offload interest notification in response to detection of the available local area network.

15. The apparatus according to claim 11, wherein the circuitry is further configured to transmit a confirmation of offload of the at least some data communication, the confirmation identifying the available local area network to which the at least some data communication is offloaded.

16. The apparatus according to claim 11, wherein the circuitry is further configured to receive, via the mobile telephony radio access network, an update to and/or a cancellation of the identified preference.
