Network, Network Nodes and Method Therein for Handling Connection in a Wireless Communication Network

A method in a wireless communication network for assisting a user equipment to handle a connection, wherein the wireless communication network comprises a first network node and a second network node, and wherein the first network node is a serving network node for the user equipment, the method comprising:

• measuring, in the user equipment, reference signals transmitted from the first and second network nodes;
• determining, in the first network node, whether the user equipment is at least one of:
• outside an idle mode coverage of the first network node and within an idle mode coverage of the second network node;
• and
• when a connection between the user equipment and the first network node is released:
• sending a context of the user equipment from the first network node to the second network node;
• and
• establishing a connection between the user equipment and the second network node.

A first network node for assisting a user equipment to handle a connection in a wireless communication network comprising the first network node and a second network node, wherein the first network node is a serving network node for the user equipment, the first network node comprising:

• at least one processor;
• and
• at least one memory storing computer-executable instructions that, when executed by the at least one processor, configure the first network node to:
• determine that the user equipment is within an idle mode coverage of the second network node based on measurements associated with the user equipment;
• when a connected mode connection between the user equipment and the first network node is released, send a context of the user equipment to the second network node.

A second network node in a wireless communication network for assisting a user equipment to handle a connection in a wireless communication network comprising the second network node and a first network node, the second network node comprising:

• at least one processor;
• and
• at least one memory storing computer-executable instructions that, when executed by the at least one processor, configure the second network node to:
• obtain a context of the user equipment from the first network node;
• and
• establish a connection with the user equipment based on the obtained context.
