Abstract:
1. A method operable on a mobile node that is usable in a wireless packet data network, the method comprising: receiving a session termination message transmitted by a first network node to all mobile nodes being served by the first network node upon the first network node encountering an outage-causing condition; responsive to receiving said session termination message delaying generation of an initial data session reconnect request, wherein said delaying is modulated based on randomized delay and said mobile node is operable to configure a suitable upper limit on said randomized delay, said suitable upper limit depending on network load statistics and traffic management history and being optimized for a certain number of data connections, the certain number being one of: the total number of data connections that are released, a minimum number of data connections that can be released or a maximum number of data connections that can be released; and after said delaying, generating a reconnect request towards a data interface operable in the wireless packet data network, wherein the data interface is operable to negotiate a data connection between the mobile node and a second network node.
