US 2003/0208601 A1 · System and method for session control in a mobile internet protocol network

Abstract

Systems and methods are shown for packet session control in a mobile communication network. One method involves conducting a first communication session on a mobile node, detecting a second communication session to be connected to the mobile node, and, responsively, determining whether the second session is accepted and the first communication session is suspended. If the first communication session is suspended, the method further involves intercepting data flow associated with the first communication session, and switching data flow associated with the second communication session to an existing air interface associated with the first communication session. In one embodiment, the air interface includes a plurality of communication channels, and the method involves switching data flow associated with the second communication session to a communication channel associated with the first communication session. In another embodiment, the method involves terminating the communication channel associated with the first communication session and setting up a second communication channel over the existing air interface to communicate data associated with the second communication session.

Claims26

Dependent claims

A method for controlling a plurality of communication sessions in a wireless communication system, the method comprising:

establishing a first communication session at a client device;
detecting a second communication session to be connected to the client device;
determining whether the second communication session is accepted on the client device;
determining whether the first communication session is put on hold on the client device to communicate data associated with the second communication session;
if so,
intercepting data flow associated with the first communication session;
and
switching data flow associated with the second communication session to an existing air interface associated with the first communication session.

5 more elements

A method for controlling a plurality of communication sessions on a mobile node, the method comprising:

communicating data associated with a first communication session on the mobile node;
receiving a first signaling message on the mobile node, the first signaling message indicating a second communication session to be connected to the mobile node;
notifying a user of the mobile node about the second communication session, wherein the user is notified using an identifier selected on the mobile node based on a data type associated with the second communication session;
determining if the second communication session is accepted by the user;
if so,
sending a second signaling message from the mobile node, the second signaling message comprising instructions to put the first communication session on hold and activate the second communication session;
intercepting a first data flow associated with the first communication session to the mobile node;
and
switching a second data flow associated with the second communication session to an air interface associated with the first communication session.
