Abstract
A wireless communication system and method of implementing an evolved system attachment procedure are disclosed. The system includes a first core network and a second core network which is evolved from the first core network. A wireless transmit/receive unit (WTRU) sends an attach request message to the second core network. The second core network activates a packet data protocol (PDP) context and sends an attach accept message to the WTRU. The attach accept message includes information regarding the PDP context. The second core network constructs a session and mobility management (SMM) context for session management (SM) and mobility management (MM) for the WTRU.

Claim
1. In an evolved wireless communication system including a first core network and a second core network, the second core network being evolved from the first core network, a method for system attachment, the method comprising: a wireless transmit/receive unit (WTRU) sending an attach request message to the second core network; the second core network activating a packet data protocol (PDP) context; and the second core network sending an attach accept message to the WTRU, the attach accept message including information regarding the PDP context.
2. The method of claim 1 wherein the attach request message includes an international mobile subscriber identity (IMSI).
3. The method of claim 1 wherein the attach request message includes a packet temporary mobile subscriber identity (P-TMSI) and a routing area identity (RAI) with respect to the first core network.
4. The method of claim 3 further comprising: the second core network sending an identification request to the first core network to obtain an international mobile subscriber identity (IMSI) from the first core network; and the first core network sending an identification response to the second core network including the IMSI if the WTRU is known in the first core network.
5. The method of claim 4 wherein the second core network derives an address of the first core network using the RAI.
6. The method of claim 4 further comprising: the first core network sending the identification response with an error message if the WTRU is not known in the first core network.
7. The method of claim 6 further comprising: the second core network sending an identity (ID) request to the WTRU to obtain the IMSI; and the WTRU sending an ID response with the IMSI.
8. The method of claim 4 further comprising: the first core network sending the identification response with an error message if the P-TMSI does not match the value stored in the first core network.
9. The method of claim 8 further comprising: the second core network sending an identity (ID) request to the WTRU to obtain the IMSI; and the WTRU sending an ID response with the IMSI
10. The method of claim 1 further comprising: the WTRU and the second core network performing authentication procedure
11. The method of claim 1 further comprising: the WTRU and the second core network performing an international mobile equipment identity (IMEI) checking procedure
12. The method of claim 1 wherein the attach request indicating an attach type
13. The method of claim 12 wherein the attach type indicates an evolved universal mobile telecommunication system (UMTS) terrestrial radio access network (E-UTRAN) only attachment
14. The method of claim 12 wherein the attach type indicates an evolved universal mobile telecommunication system (UMTS) terrestrial radio access network (E-UTRAN) and IMSI attachment
15. The method of claim 1 wherein the attach accept message includes at least one of a PDP type, a PDP address, a transaction identifier (TI), quality of service (QoS), radio priority, a packet flow identifier and PDP configuration
16. The method of claim 1 further comprising: the second core network constructing a session and mobility management (SMM) context for SM and MM for the WTRU
17. The method of claim 16 wherein a state of the SMM is defined as one of an MM-detached and SM-inactive state, an MM-connected and SM-active state and an MM-idle and SM-active state
18. The method of claim 16 wherein an SMM state of the WTRU changes depending on allocation of PDP address to the WTRU
19. The method of claim 1 further comprising: the second core network rejecting the attach request if the WTRU is not allowed in a routing area (RA) with respect to the second core network.
20. A wireless communication system comprising: a first core network; a second core network evolved from the first core network; and a wireless transmit/receive unit (WTRU) configured to send an attach request message to the second core network, wherein the second core network is configured to activate a packet data protocol (PDP) context for the WTRU and send an attach accept message to the WTRU including information regarding the PDP context.
21. The system of claim 20 wherein the attach request message includes an international mobile subscriber identity (IMSI).
22. The system of claim 20 wherein the attach request message includes a packet temporary mobile subscriber identity (P-TMSI) and a routing area identity (RAI) with respect to the first core network.
23. The system of claim 22 wherein the second core network is configured to send an identification request to the first core network to obtain an international mobile subscriber identity (IMSI) from the first core network and the first core network is configured to send an identification response to the second core network including the IMSI if the WTRU is known in the first core network.
24. The system of claim 23 wherein the second core network derives an address of the first core network using the RAI.
25. The system of claim 23 wherein the first core network is configured to send the identification response with an error message if the WTRU is not known in the first core network.
26. The system of claim 25 wherein the second core network is configured to send an identity (ID) request to the WTRU to obtain the IMSI and the WTRU is configured to send an ID response with the IMSI.
27. The system of claim 23 wherein the first core network is configured to send the identification response with an error message if the P-TMSI does not match the value stored in the first core network.
28. The system of claim 27 wherein the second core network is configured to send an identity (ID) request to the WTRU to obtain the IMSI and the WTRU is configured to send an ID response with the IMSI.
29. The system of claim 20 wherein the WTRU and the second core network are configured to perform authentication procedure.
30. The system of claim 20 wherein the WTRU and the second core network are configured to perform an international mobile equipment identity (IMEI) checking procedure with an equipment identity register (EIR).
31. The system of claim 20 wherein the attach request indicating an attach type.
32. The system of claim 31 wherein the attach type indicates an evolved universal mobile telecommunication system (UMTS) terrestrial radio access network (E-UTRAN) only attachment.
33. The system of claim 31 wherein the attach type indicates an evolved universal mobile telecommunication system (UMTS) terrestrial radio access network (E-UTRAN) and IMSI attachment.
34. The system of claim 20 wherein the attach accept message includes at least one of a PDP type, a PDP address, a transaction identifier (TI), quality of service (QoS), radio priority, a packet flow identifier and PDP configuration.
35. The system of claim 20 wherein the second core network is configured to construct a session and mobility management (SMM) context for session management (SM) and mobility management (MM) for the WTRU.
36. The system of claim 35 wherein a state of the SMM is defined as one of an MM-detached and SM-inactive state, an MM-connected and SM-active state and an MM-idle and SM-active state.
37. The system of claim 35 wherein an SMM state of the WTRU changes depending on allocation of PDP address to the WTRU.
38. The system of claim 20 wherein the second core network is configured to reject the attach request if the WTRU is not allowed in a routing area (RA) with respect to the second core network.
39. A state machine for session and mobility management (SMM), comprising: a mobility management (MM)-detached and session management (SM)- inactive state indicating a WTRU is detached and PDP context is not activated; an MM-connected and SM-active state indicating the WTRU is attached and PDP context is activated and an SM connection is established; and an MM-idle and SM-active state indicating the WTRU is attached, PDP context is activated and the SM connection is released.']
