Abstract
The present invention relates to a method for closing all network connections to a detached user equipment. The local mobility anchor (LMA) receives and reads a control message saying that the user equipment is detached and all the network connections must be closed. The LMA performs the instructions in the control message, i.e. closes all the network connections to the user equipment. After the instructions have been executed, the LMA sends an acknowledgement back to indicate which actions have been performed. Thus, the closing of all network connections is done using only one message exchange and thereby saving signalling in the Core Network.
