Claim
1. A method, comprising:
communicating between a communication device and a first access system using a given address;
initiating transfer of the communication device to a second access system;
sending from the communication device an attach message parameter in an attach procedure to a gateway entity associated with the second access system to initiate the transfer, wherein the attach procedure is using an IKEv2 configuration payload message with the attach message parameter indicating that the given address is to be used in the second access system; and
based on proxy mobility functionality being available for the given address at the gateway entity associated with the second access system, being assigned by the second access system a same address as the given address to perform the communication in the second access system, wherein the first access system comprises a third generation (3G) access system and the second access system comprises a non-3G access system or vice versa.
2. The method as claimed in claim 1, comprising sending from the communication device a request for information if the given address can be used in the second access system.
3. The method as claimed in claim 2, wherein the communication device is a mobile communication device.
4. The method of claim 2, wherein the request comprises a request for information of whether the given address is served by a proxy mobile internet entity.
5. The method of claim 1, comprising receiving at the communication device an indication that network provided mobility is available.
6. The method of claim 1, comprising creating by the communication device an address other than the given address for use in the first and second access systems.
7. The method as claimed in claim 1, comprising sending from the communication device a request for an address other than the given address that can be used in at least two different access systems.
8. The method as claimed in claim 1, wherein the gateway entity is a packet data gateway.
9. The method as claimed in claim 1, wherein the proxy mobility available for the given address at the gateway entity is based on proxy mobile internet protocol.
10. The method as claimed in claim 1, wherein the given address is an internet protocol address, and the method comprising using the internet protocol address over a different link layer to communicate in the second access system.
11. The method as claimed in claim 1, wherein the attach procedure comprises an attachment to a third generation (3G) access system.
12. A non-transitory carrier medium including a computer program product comprising a set of instructions, the instructions executed by a processor in a node of a communication system to cause the node to perform operations comprising:
using by a communication device a given address for a session provided by a first access system,
sending an attach message parameter in an attach procedure to a gateway entity associated with a second access system to initiate a transfer of the communication device to the second access system, wherein the attach procedure is using an IKEv2 configuration payload message with the attach message parameter indicating that the given address is to be used by the mobile communication device in the second access system, and
based on proxy mobility functionality being available for the given address at the gateway entity associated with the second access system, being assigned by the second access system a same address as the given address to continue the session in the second access system, wherein the first access system comprises a third generation (3G) access system and the second access system comprises a non-3G access system or vice versa.
13. The non-transitory carrier medium as claimed in claim 12, further comprising sending a request for information if the given address can be used in the second access system.
14. The non-transitory carrier medium as claimed in claim 12, wherein the gateway entity is a packet data network gateway.
15. The non-transitory carrier medium as claimed in claim 12, wherein the proxy mobility available for the given address at the gateway entity is based on proxy mobile internet protocol.
16. An apparatus, comprising
at least one processor; and
at least one memory including computer program code, where the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to at least:
use a given address in a first access system,
send an attach message parameter in an attach procedure to a gateway entity associated with the second access system to initiate a transfer of the apparatus to the second access system, wherein the attach procedure is using an IKEv2 configuration payload message with the attach message parameter indicating that the given address is to be used in the second access system, and
based on proxy mobility functionality for the given address at the gateway entity associated with the second access system, being assigned by the second access system a same address as the given address for communication in the second access system, wherein the first access system comprises a third generation (3G) access system and the second access system comprises a non-3G access system or vice versa.
17. The apparatus of claim 16, wherein the at least one memory including the computer program code is configured, with the at least one processor, to cause the apparatus to send a request for information regarding whether the address can be used in the second access system.
18. The apparatus of claim 16, wherein the apparatus comprises a mobile communication device.
19. The apparatus of claim 18, wherein the given address is an internet protocol address, and the method comprising using the internet protocol address over a different link layer to communicate in the second access system.
20. The apparatus of claim 16, wherein the gateway entity is a packet data network gateway.
21. The apparatus of claim 16, wherein the proxy mobility available for the given address at the gateway entity is based on proxy mobile internet protocol.
22. The apparatus of claim 16, wherein the communication device is a mobile communication device.
23. An apparatus comprising:
at least one processor; and
at least one memory including computer program code, where the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to at least:
receive an indication in an IKEv2 message that a given address is to be used in at least two different access systems;
provide a communication device with information in an attach message in an attach procedure to a gateway entity of a different access network that enables a communication session with the communication device based on the given address of the communication device in the at least two different access systems when proxy mobility is provided a same address as the given address at a gateway entity associated with the at least two different access systems, wherein the at least two different access systems comprise a first access system associated with a third generation (3G) access system and a second access system associated with a non-3G access system.
24. The apparatus of claim 23, wherein the gateway entity is a packet data network gateway and wherein the proxy mobility provided for the given address at the packet data network gateway is based on proxy mobile internet protocol.
