1. A method, comprising:
- maintaining, by a user equipment, network connections comprising a first connection between a first network node and the user equipment and a second connection between a second network node and the user equipment, the first network node having a first network node type and the second network node having a second network node type different from the first network node type;
determining, by the user equipment, a third network node for establishing a third connection between the third network node and the user equipment, in response to a link failure of the second connection, the third network node having the second network node type;
sending, by the user equipment and in response to the link failure, an instruction to transfer context information of the user equipment from the first network node to the third network node, while maintaining the first connection between the first network node and the user equipment; and
establishing, by the user equipment and in response to the link failure, the third connection between the third network node and the user equipment, the third connection established based on the transferred context information.

Abstract
An enhanced connection control including maintaining a first connection between a first network node and a user equipment which has a second connection with a second network node, determining a third network node for re-establishing a third connection between the third network node and the user equipment, in response to a link failure of the second connection, and transferring context information of the user equipment from the first network node to the third network node.

9. An apparatus, comprising:
-
at least one processor; and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least; maintain a first connection between the apparatus and a user equipment which has a second connection with another apparatus, the apparatus having a first apparatus type and the another apparatus having a second apparatus type different from the first apparatus type; determine a target apparatus for establishing a third connection between the target apparatus and the user equipment, in response to a link failure of the second connection, the target apparatus having the second apparatus type; and transfer, to the target apparatus and in response to the link failure, context information of the user equipment to establish the third connection between the target apparatus having the second apparatus type and the user equipment, while maintaining the first connection between the apparatus and the user equipment. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method, comprising:
-
maintaining, by a user equipment, network connections comprising a first connection between a first network node and the user equipment and a second connection between a second network node and the user equipment, the first network node having a first network node type and the second network node having a second network node type different from the first network node type; detecting, by the user equipment, a link failure of the second connection; sending, by the user equipment and in response to the link failure, a message to the first network node to instruct the first network node to transfer context information of the user equipment to a third network node, the third network node having the second network node type; and performing, by the user equipment and in response to the link failure, an establishment procedure for a third connection with the third network node having the context information transferred from the first network node and having the second network node type, while maintaining the first connection between the first network node and the user equipment. - View Dependent Claims (16, 17)
