1. A method for network communication between a mobile terminal and a remote entity in a network, the method comprising:
- establishing a first connection over a network between a mobile terminal and a remote entity;
sending, from the mobile terminal, keep-alive messages at varying intervals via the first connection in response to inactivity in the first connection;
wherein the first connection is disconnected after a first period of inactivity;
establishing a second connection over the network between the mobile terminal and the remote entity;
sending, from the mobile terminal, keep-alive messages at varying intervals via the second connection in response to inactivity in the second connection;
wherein the second connection is disconnected after a second period of inactivity;
sending, from the mobile terminal, keep-alive messages at a safe interval via a subsequent connection over the network in response to inactivity in the subsequent connection, wherein the safe interval is based on the first disconnection and the second disconnection.

Abstract
A method for IP [=Internet Protocol] communication between a mobile terminal and its correspondent node in a mobile radio network. The method comprises establishing an IP connection between the mobile terminal and its correspondent node. After detecting a period of inactivity in the IP connection, keep-alive messages are sent via the IP connection at predetermined intervals, which are varied. The method comprises monitoring the lengths of several periods of inactivity at which the mobile radio network disconnects the IP connection.

15. A mobile terminal comprising:
-
a communications interface; a battery; the mobile terminal in conjunction with the communications interface is configured for; establishing a first connection over a network between a mobile terminal and a remote entity; sending, from the mobile terminal, keep-alive messages at varying intervals via the first connection in response to inactivity in the first connection; wherein the first connection is disconnected after a first period of inactivity; establishing a second connection over the network between the mobile terminal and the remote entity; sending, from the mobile terminal, keep-alive messages at varying intervals via the second connection in response to inactivity in the second connection; wherein the second connection is disconnected after a second period of inactivity; sending, from the mobile terminal, keep-alive messages at a safe interval via a subsequent connection over the network in response to inactivity in the subsequent connection, wherein the safe interval is based on the first disconnection and the second disconnection. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
