Abstract

Some demonstrative embodiments include devices, systems of selectively providing Internet Protocol (IP) session continuity. In one example, a mobile device may include a radio to communicate with a wireless network, the radio to transmit a session setup request to setup a communication session, and to receive a session setup response in response to the session setup request, the session setup response including a first Internet Protocol (IP) address and a second IP address assigned to the communication session, and an indication that the first IP address is configured to maintain IP session continuity; and a controller to select to use the first IP address for the communication session, if IP session continuity is to be maintained for the communication session, and to select to use the second IP address for the communication session, if IP session continuity is not to be maintained for the communication session.

Claims

1. A mobile device comprising:

a radio to communicate with a wireless network, the radio to transmit a session setup request to setup a communication session, and to receive a session setup response in response to the session setup request, the session setup response comprising a first Internet Protocol (IP) address and a second IP address assigned to the communication session, and an indication that the first IP address is configured to maintain IP session continuity; and

a controller to select to use the first IP address for said communication session, if IP session continuity is to be maintained for the communication session, and to select to use the second IP address for said communication session, if IP session continuity is not to be maintained for the communication session, said controller is to select between said first and second IP addresses based on one or more attributes of traffic to be communicated during the communication session.

2. The mobile device of claim 1, wherein said first and second IP addresses comprise addresses provided by a Dynamic Host Configuration Protocol (DHCP) server.

3. The mobile device of claim 1, wherein said controller is to select between said first and second IP addresses based on a type of an application to use said communication session.

4. The mobile device of claim 1 being a User Equipment (UE), the radio to transmit said session setup request via a first message to an Evolved Node B (eNB), and to receive the session setup response via a second message from the eNB.

5. The mobile device of claim 1, wherein said first IP address comprises an address of a first Packet Data Network (PDN) connection, and the second IP address comprises an address of a second PDN connection.

6. The mobile device of claim 5, wherein the first PDN connection is terminated at a first gateway (GW), and the second PDN connection is terminated at a second GW.

7. The mobile device of claim 6, wherein the first GW comprises a PDN GW (PGW), and the second GW comprises a Local GW (LGW).

8. The mobile device of claim 5, wherein the session setup request comprises a PDN connection request, and the session setup response comprises a PDN connection response.

9. The mobile device of claim 1 comprising:

one or more antennas;

a processor;

a memory;

an input unit; and

an output unit.

10. A mobility manager in a wireless communication network, the mobility manager comprising:

an interface to receive a request to setup a communication session for a mobile device; and

a controller to select to configure a session connection for the communication session to guarantee Internet Protocol (IP) session continuity, when IP session continuity is to be guaranteed for the communication session, and to select to configure said session connection without IP session continuity guarantee, when IP session continuity is not to be guaranteed for the communication session, said controller is to determine whether or not IP session continuity is to be guaranteed for the communication session based on a type of traffic to be communicated during the communication session,

wherein said controller is to request a mobility anchor to setup a routing override for said session connection, only if the controller selects to configure the session connection to guarantee IP session continuity.
