Wireless Communications Device and Methods for Handling Communications with Two or More Networks

A method, performed by a wireless communications device comprising at least two Subscriber Identity Modules (SIMs) and at least two independent receiver chains and at least two independent transmitter chains, for handling communication with two or more wireless communications networks, the method comprising:

• registering with a first wireless communications network associated with a first SIM of the wireless communications device by providing, to a first network node associated with the first wireless communications network, one or more first capabilities of the wireless communications device associated with the at least two independent receiver chains and the at least two independent transmitter chains;
• registering with a second wireless communications network associated with a second SIM of the wireless communications device by providing, to a second network node associated with the second wireless communications network, one or more second capabilities of the wireless communications device associated with the at least two independent receiver chains and the at least two independent transmitter chains;
• upon being connected to the first wireless communications network and using the one or more first capabilities for a service, transmitting a first request to the first network node to disable a set of capabilities from the one or more first capabilities provided to the first network node;
• connecting to the second network node and using the set of capabilities for a service in the second wireless communications network once the first network node accepts the first request and disables the set of capabilities, such that the wireless communications device is connected to the first network node with reduced capabilities without the set of capabilities, and the wireless communications device is connected to the second network node using the set of capabilities;
• and
• when the wireless communications device has disconnected from the second network node and continues to be connected to the first network node using the reduced capabilities, managing a re-enabling procedure of the capabilities by:
• triggering a second request to the first network node to re-enable the set of capabilities for communication with the first network node based on whether a first a first condition for triggering the re-enablement is fulfilled, or
• not triggering the second request to the first network node to re-enable the set of capabilities for communication with the first network node based on whether a second condition for not triggering the re-enablement is fulfilled.

A wireless communications device comprising at least two Subscriber Identity Modules (SIMs) and at least two independent receiver chains and at least two independent transmitter chains, configured for handling communication with two or more wireless communications networks, the wireless communications device being further configured to:

• register with a first wireless communications network associated with a first SIM of the wireless communications device, by providing, to a first network node associated with the first wireless communications network, one or more first capabilities of the wireless communications device associated with the at least two independent receiver chains and the at least two independent transmitter chains;
• register with a second wireless communications network associated with a second SIM of the wireless communications device, by providing, to a second network node associated with the second wireless communications network, one or more second capabilities of the wireless communications device associated with the at least two independent receiver chains and the at least two independent transmitter chains;
• upon being connected to the first wireless communications network and using the one or more first capabilities for a service, transmit a first request to the first network node to disable a set of capabilities from the one or more first capabilities provided to the first network node;
• connect to the second network node and using the set of capabilities for a service in the second wireless communications network once the first network node accepts the first request and disables the set of capabilities, such that the wireless communications device is connected to the first network node with reduced capabilities without the set of capabilities, and the wireless communications device is connected to the second network node using the set of capabilities;
• and
• when the wireless communications device has disconnected from the second network node and continues to be connected to the first network node using the reduced capabilities, manage a re-enabling procedure of the capabilities by being configured to:
• trigger a second request to the first network node to re-enable the set of capabilities for communication with the first network node based on whether a first a first condition for triggering the re-enablement is fulfilled, or
• not trigger the second request to the first network node to re-enable the set of capabilities for communication with the first network node based on whether a second condition for not triggering the re-enablement is fulfilled.
