Methods, network nodes, communication device, computer programs and computer program products for re-establishment of a connection
First Claim
1. A method performed in a target network node for re-establishing a connection to a communication device, the method comprising:
- receiving, from the communication device, a request for a re-establishment of the connection, the request comprising a first identifier identifying a management node and a second identifier uniquely identifying a source cell of the communication device, wherein the first identifier identifying the management node comprises a Globally Unique Mobility Management Entity Identifier, GUMMEI, of a management node with which the communication device was last registered, and wherein the second identifier uniquely identifying the source cell comprises a Cell Global Identity, CGID, of the source cell to which the communication device was last connected to,obtaining a context for the communication device based on at least one of the first identifier and the second identifier, andre-establishing the connection to the communication device.
