Abstract
A method and a device in a communication apparatus for maintaining an established connection between said apparatus and a network node. The connection is established by a mobility management unit for providing a mobility management procedure. An acceptance message is issued by the node in response to a request relating to a first mobility management procedure. If any request relating to a second mobility management procedure issued by an upper layer is received by the mobility management unit after the request relating to the first procedure is transmitted and before the acceptance message is received, a maintaining request to maintain the connection is transmitted to the node in response to the acceptance message.
