Abstract:
A method (100) performed in a target network node (12) is provided for re-establishing a connection to a communication device (11). The method (100) comprises receiving (101), from the communication device (11), a request for a re-establishment of the connection, the request comprising a first identifier identifying a management node (14) and a second identifier uniquely identifying a source cell of the communication device (11); obtaining (102) a context for the communication device (11) based on at least one of the first identifier and the second identifier; and re-establishing (103) the connection to the communication device (11). Methods in source network node (13), management node (14) and communication devices (11) are also provided, and corresponding nodes, computer programs and computer program products.
