Method and apparatus for resource restriction

A first network node, comprising:

• one or more processors;
• and
• one or more memories comprising computer program codes,
• the one or more memories and the computer program codes configured to, with the one or more processors, cause the first network node at least to:
• obtain first information for a terminal device which communicates with the first network node using a first radio access technology, the first information indicating that there is a restriction on use of a second radio access technology by the terminal device;
• determine that the terminal device is allowed to use a first resource set which is provided by a second network node for the second radio access technology, according to the first information and that the first network node has second information to indicate a second resource set for the second radio access technology, the second resource set being different from the first resource set and not available for the terminal device when there is the restriction on use of the second radio access technology by the terminal device;
• and
• determine, in response to having the second information for the terminal device, that the terminal device is allowed to use the first resource set.

A method performed by a terminal device, comprising:

• receiving, from a first network node using a first radio access technology, a message to request information of the terminal device regarding at least a first resource set which is provided by a second network node for a second radio access technology;
• and
• transmitting the requested information of the terminal device to the first network node,
• the message being based at least in part on first information and second information for the terminal device, the first information indicating that there is a restriction on use of the second radio access technology by the terminal device, the second information indicating a second resource set for the second radio access technology, and when there is the restriction on use of the second radio access technology by the terminal device, the terminal device is allowed to use the first resource set but not allowed to use the second resource set.
