Maintaining communication sessions
First Claim
1. A method of communicating between a server and a terminal, wherein said terminal establishes a first communication path with said server via a first allocated address;
- the server allocates an identification reference to a communication session upon initiation of said communication session, wherein during said communication session said first communication path is closed and replaced by a second communication path with said server via a second allocated address; and
the server maintains said communication session after replacement of the first communication path with the second communication path by identifying said identification reference and communicating with said remote station via said second allocated address.

Abstract
Communication occurs between a server and a terminal. The terminal establishes a first communication path with the server via a first allocated address. The server allocates an identification reference to a communication session upon initiation of said communication session. During the communication session the first communication path is closed and replaced by a second communication path with said server via a second allocated address. The server maintains said communication session after replacement of the first communication path with the second communication path by identifying said identification reference and communicating with said remote station via said second allocated address.

4. A method of communicating between a server and a terminal, wherein
said terminal establishes a first communication path with said server via a first allocated address; -
the server allocates an identification reference to a communication session upon initiation of said communication session; and
during said communication session said first communication path is closed and replaced by a second communication path with said server via a second allocated address;
whereinthe server maintains said communication session after replacement of the first communication path with the second communication path by identifying said identification reference and communicating with said remote station via said second allocated address; and
said communication path includes a first radio network, and said first communication path is closed and replaced by said second communication path when said terminal stops using said first radio network and starts using a second radio network.

5. A server configured to transmit data packets to at least one terminal, wherein
said terminal establishes a first communication path with said server via a first allocated address; -
the server allocates an identification reference to a communication session upon initiation of said communication session;
during said communication session said first communication path is closed and replaced by a second communication path with said server via a second allocated address; and
the server maintains said communication session after replacement of the first communication path with the second communication path by identifying said identification reference and communicating with said remote station via said second allocated address. - View Dependent Claims (6, 7, 8)

9. Instructions executable by a network of computers and/or programmable data processing devices such that when executing said instructions stations connected to said network will transmit data packets over said network and said network will perform the steps of
establishing a first communication path between a first station and a second station via a first allocated address; -
allocating an identification reference to a communication session upon initiation of said communication session, wherein during said communication session said first communication path is closed and replaced by a second communication path via a second allocated address; and
maintaining said communication session after replacement of the first communication path with the identification reference and communicating with said remote station via said second allocated address. - View Dependent Claims (10, 11)

12. Instructions executable by a combination of a server and mobile terminal connected to a said server by a radio network such that when executing said instructions said combination performs the steps of
at a terminal, establishing a first communication path with the server via a first allocated address; -
at the server, allocating an identification reference to a communication session upon initiation of said communication session;
whereinduring said communication session said first communication path is closed and replaced by a second communication path with said server via a second allocated address; and
the server maintains said communication session after replacement of the first communication path with the second communication path by identifying said identification reference and communicating said identification reference and communicating with said remote station via said second allocated address. - View Dependent Claims (13, 14)

15. A computer readable medium having computer readable instructions executable by a computer such that when executing said instructions a computer will perform the steps of:
-
responding to a first communication path established by a networked device via a first allocated address;
allocating an identification reference to a communication session upon initiation of said communication session, wherein during said communication session said first communication path is closed and replaced by a second communication path via a second allocated address; and
maintaining said communication session after replacement of the first communication path with the second communication path by identifying said identification reference and communicating with said remote station via said second allocated address. - View Dependent Claims (16, 17)
