Abstract

The disclosure pertains to the field of dual access handling. More particularly the disclosure relates to methods of handling more than one connection, each connection corresponding to a respective subscriber identity and connecting a wireless device to a respective wireless network, as well as to a corresponding wireless device and to a computer program. This object is obtained by a method, performed in a wireless device 1, of handling multi access of more than one connection, each connection corresponding to a respective subscriber identity and connecting the wireless device to a respective wireless network. The method comprises detecting S 1, for a first connection corresponding to a first subscriber identity, a change in connection properties, and determining S 2, for at least one of the other subscriber identities, a set of updated network capabilities, based on the changed connection properties of the first connection.

First claim

1 - 24 . (canceled)

25 . A method, performed in a wireless device, of handling multi access of more than one connection, each connection corresponding to a respective subscriber identity and connecting the wireless device to a respective wireless network, the method comprising:
detecting, for a first connection corresponding to a first subscriber identity, a change in connection properties; and determining, for at least one of the other subscriber identities, a set of updated network capabilities, based on the changed connection properties of the first connection.

26 . The method of claim 25 , wherein the detecting comprises detecting a transition from idle connection state to active connection state, or vice versa, of the first connection.

27 . The method of claim 25 , wherein the detecting comprises detecting a handover or handover request of the first connection.

28 . The method of claim 25 , wherein the determining comprises determining combinations of network capabilities feasible for connections in multi access mode.

29 . The method of claim 25 , wherein the determining comprises using a lookup table with combinations of network capabilities feasible for connections in multi access mode.

30 . The method of claim 25 , wherein the connection properties comprise at least one of: connection state, frequency bandwidth, carrier frequency, modulation, and power level.

31 . The method of claim 25 , further comprising:
setting, for each subscriber identity, an initial set of network capabilities.

32 . The method of claim 31 , wherein the initial set is equal to the network capabilities of the wireless device.

33 . The method of claim 25 , wherein the subscriber identity is a Subscriber Identity Module (SIM).

34 . The method of claim 25 , further comprising:
activating a second connection corresponding to a second subscriber identity using the respective determined set of updated network capabilities.

35 . The method of claim 25 , further comprising:
terminating at least one active connection based on the determined set of updated network capabilities.

36 . The method of claim 25 , wherein the subscriber identities have different priorities.

37 . The method of claim 25 , further comprising:
reporting at least one determined set of updated network capabilities to a respective communication network.

38 . The method of claim 25 , further comprising:
denying a handover request of a second connection corresponding to a second subscriber identity if not complying with the respective determined set of updated network capabilities.

39 . The method of claim 25 , wherein network capabilities comprises at least one of the following parameters: supported radio access technology, carrier frequency, MIMO capabilities, UE category, Radio Link Protocol parameters, radio parameters, measurement parameters, inter-RAT parameters.

40 . A wireless device, configured for handling multi access of more than one connection corresponding to a respective subscriber identity, the wireless device comprising:
at least two subscriber identities; a radio communication interface for communication with at least one communication network; and processing circuitry configured to cause the wireless device:
to detect, for a first connection corresponding to a first subscriber identity, a change in connection properties of the radio communication interface, and
to determine, for at least one of the other subscriber identities, a set of updated network capabilities, based on the changed connection properties of the first connection.

41 . The wireless device of claim 40 , wherein the processing circuitry is further configured to set, for each subscriber identity, an initial a set of network capabilities.

42 . The wireless device of claim 40 , wherein the subscriber identity is a Subscriber Identity Module (SIM).

43 . The wireless device of claim 40 , wherein the processing circuitry is further configured to activate a second connection corresponding to a second subscriber identity using the respective determined set of updated network capabilities.

44 . The wireless device of claim 40 , wherein the processing circuitry is further configured to terminate at least one active connection based on the determined set of updated network capabilities.

45 . The method of claim 40 , wherein the subscriber identities have different priorities.

46 . The wireless device of claim 40 , wherein the processing circuitry is further configured to report the at least one determined set of updated network capabilities to a respective communication network.

47 . The wireless device of claim 40 , wherein the processing circuitry is further configured to deny a handover request of a second connection corresponding to a second subscriber identity if not complying with the determined set of updated network capabilities.

48 . A non-transitory computer-readable medium comprising, stored thereupon, a computer program comprising computer program code that, when executed in a wireless device configured to support multi access of more than one connection, each connection corresponding to a respective subscriber identity and connecting the wireless device to a respective wireless network, causes the wireless device to:
detect, for a first connection corresponding to a first subscriber identity, a change in connection properties; and determine, for at least one of the other subscriber identities, a set of updated network capabilities, based on the changed connection properties of the first connection
