Abstract

A method, apparatus and computer program product are provided in which the network is informed of a connection break with a device having multiple SIMs. In this regard, from the perspective of the device, information regarding a connection break with the device is provided to a network entity associated with a first network, the device communicating with the first network via a first subscription. The method may also cause the connection break to be initiated and causing another connection to be established with the device via a second subscription. From the perspective of the network, a method, apparatus and computer program product are provided in which the network receives information regarding the connection break and, based on the information, performs one or more network optimization actions.

First claim

That which is claimed:

1. A method comprising:
transmitting, by a mobile terminal and to an access point, information regarding a connection break in an ongoing connection between the mobile terminal and a first network, the access point associated with the first network, the mobile terminal associated with a plurality of subscriptions and communicating with the first network via a first subscription of the plurality of subscriptions, wherein the information comprises an indication of a repetition interval of the connection break and an indication of a duration of the connection break;
causing, at the mobile terminal and after transmitting the information, the connection break in the ongoing connection to be initiated; and
causing, at the mobile terminal and after the connection break is initiated, another connection to be established with the mobile terminal using a second subscription of the plurality of subscriptions.

2. The method of claim 1 , wherein the information further comprises an indication of at least one of a start time of the connection break or an end time of the connection break.

3. The method of claim 1 , wherein the information comprises a reason for the connection break.

4. The method of claim 1 , wherein the information comprises a request to either resume the ongoing connection following the connection break or release the ongoing connection.

5. The method of claim 1 , further comprising:
performing, by the mobile terminal, an activity related to multiple subscription operation on the another connection using the second subscription.

6. The method of claim 1 , wherein the information comprises a signaling connection release indication.

7. The method of claim 6 , wherein the signaling connection release indication comprises a cause value indicating a reason for requesting release of the ongoing connection.

8. The method of claim 1 , wherein causing the another connection to be established with the mobile terminal comprises establishing the another connection with a second network.

9. The method of claim 1 , wherein the mobile terminal includes a dual subscriber identity module configured to include the first subscription and the second subscription.

10. An apparatus comprising at least one processor and at least one memory storing program code instructions therein, the memory and program code instructions being configured to, with the processor, cause the apparatus to at least:
transmit, to an access point, information regarding a connection break in an ongoing connection between the apparatus and a first network, the access point associated with the first network, the apparatus associated with a plurality subscriptions and communicating with the first network via a first subscription of the plurality of subscriptions, wherein the information comprises an indication of a repetition interval of the connection break and an indication of a duration of the connection break;
cause, after transmitting the information, the connection break in the ongoing connection to be initiated; and
cause, after the connection break is initiated, another connection to be established with the apparatus using a second subscription of the plurality of subscriptions, wherein the apparatus includes a mobile terminal.

11. The apparatus of claim 10 , wherein the information further comprises an indication of at least one of a start time of the connection break or an end time of the connection break.

12. The apparatus of claim 10 , wherein the information comprises a reason for the connection break.

13. The apparatus of claim 10 , wherein the information comprises a request to either resume the ongoing connection following the connection break or release the ongoing connection.

14. The apparatus of claim 10 , wherein the apparatus is further caused to at least:
perform an activity related to multiple subscription operation on the another connection using the second subscription.

15. The apparatus of claim 10 , wherein the information comprises a signaling connection release indication.

16. The apparatus of claim 15 , wherein the signaling connection release indication comprises a cause value indicating a reason for requesting release of the ongoing connection.

17. The apparatus of claim 10 , wherein causing the another connection to be established comprises establishing the another connection with a second network.

18. An apparatus comprising a processor and a memory storing program code instructions therein, the memory and program code instructions being configured to, with the processor, cause the apparatus to at least:
receive, from a mobile terminal, information regarding a connection break in an ongoing connection between the mobile terminal and a first network, the apparatus associated with the first network, the mobile terminal associated with a plurality of subscriptions and communicating with the first network via a subscription of the plurality of subscriptions, wherein the information comprises an indication of a repetition interval of the connection break and an indication of a duration of the connection break; and
based on the information, perform one or more network optimization actions, wherein the apparatus comprises an access point.

19. The apparatus of claim 18 , wherein the information further comprises an indication of at least one of a start time of the connection break or an end time of the connection break.

20. The apparatus of claim 18 , wherein the information comprises a reason for the connection break.

21. The apparatus of claim 18 , wherein the information comprises a request to either resume the ongoing connection following the connection break or release the ongoing connection.
