Abstract

Systems, methods, and instrumentalities are disclosed such that a WTRU may obtain network operator agnostic wireless access for a service. The WTRU may receive a system information (SI) broadcast from a radio access network (RAN) node. The SI broadcast may indicate that an operator of the RAN node supports service-based network access. The WTRU may send a service request to a virtual service provider to request the service. The WTRU may receive a service response from the virtual service provider. The WTRU may receive a service response from the virtual service provider, the service response indicating a mobile network operator (MNO) to use for obtaining the service and subscription information for accessing the MNO, wherein the MNO is different than the operator of the RAN node. The WTRU may access the MNO to obtain the service.

First claim

What is claimed:

1. A method implemented by a wireless transmit receive unit (WTRU), the method comprising:
receiving a system information (SI) broadcast from a radio access network (RAN) node, the SI broadcast indicating that an operator of the RAN node supports service-based network access, wherein the service-based network access is RAN operator agnostic;
sending, via the RAN node, one or more of a service request to a virtual service provider to request the service, a validation method, or a payment method, wherein, the service request comprises one or more of a service type; a service duration, or a quality of service (QoS);
receiving a service response from the virtual service provider, the service response indicating a mobile network operator (MNO) to use for obtaining the service and subscription information for accessing the MNO, wherein the MNO is different than the operator of the RAN node;
establishing a first network connection using a first radio access technology;
utilizing the first network connection to communicate with a server virtualizing resources for a second radio access technology utilized by the WTRU; and
accessing the MNO to obtain the service.

2. The method of claim 1 , wherein the WTRU lacks a subscription with either the operator of the RAN node or the MNO.

3. The method of claim 1 , wherein the service request is sent as part of an attach request.

4. The method of claim 3 , wherein the attach request is of access cloud service type.

5. The method of claim 3 , wherein the WTRU attaches to the RAN node in a limited state in order to determine an operator network to use for accessing the service.

6. The method of claim 5 , wherein the limited state limits at least one of an amount of time the WTRU is allowed to be attached, a destination the WTRU is allowed to access, a priority associated with requests sent by the WTRU, or bearer parameters for the WTRU.

7. The method of claim 1 , wherein the service response is received in a detach message.

8. The method of claim 1 , further comprising authenticating with the MNO based on the subscription information received in the service response.

9. The method of claim 1 , wherein the WTRU is a light WTRU.

10. The method of claim 9 , further comprising communicating with a cloud WTRU, wherein the cloud WTRU performs a processor or memory intense function.

11. The method of claim 10 , wherein the processor or memory intense function comprises one or more of re-authentications, or temporarily storing videos.

12. The method of claim 1 , wherein the service request comprises a global access point name (APN).

13. The method of claim 12 , wherein the global APN comprises one or more of a network identifier, a virtual network (VN) identifier, or an operator identifier.

14. The method of claim 3 , wherein the attach request comprises an indication to support dynamic virtual network (VN) extension.

15. The method of claim 1 , further comprising selecting a virtual network (VN) and indicating the selected VN in a PreAttach message.

16. The method of claim 15 , wherein the PreAttach message comprises one or more of a VN capability, or a VN identifier.

17. The method of claim 1 , wherein the service request comprises an access specific information of a virtual network (VN).

18. The method of claim 17 , wherein the access specific information comprises one or more of a virtual network identifier (VN-ID), a virtual network indicator (VN-indicator), a virtual network permission number (VN-permission-number), one or more security-credentials, a virtual network privilege or priority number (VN-privilege/priority-number), an access location information (access-location-info), one or more of available access network nodes (available-access-network-nodes), a service identifier (service-ID), an application identifier (App-ID), a desired QoS level, or a price.

19. A wireless transmit receive unit (WTRU) comprising:
a processor configured to:
receive a system information (SI) broadcast from a radio access network (RAN) node, the SI broadcast indicating that an operator of the RAN node supports service-based network access, wherein the service-based network access is RAN operator agnostic;
send, via the RAN node, one or more of a service request to a virtual service provider to request the service, a validation method, or a payment method, wherein, the service request comprises one or more of a service type, a service duration, or a quality of service (QoS);
receive a service response from the virtual service provider, the service response indicating a mobile network operator (MNO) to use for obtaining the service and subscription information for accessing the MNO, wherein the MNO is different than the operator of the RAN node;
establish a first network connection using a first radio access technology;
utilize the first network connection to communicate with a server virtualizing resources for a second radio access technology utilized by the WTRU; and
access the MNO to obtain the service.

20. The WTRU of claim 19 , wherein the WTRU lacks a subscription with either the operator of the RAN node or the MNO.

21. The WTRU of claim 19 , wherein the service request is sent as part of an attach request.

22. The WTRU of claim 21 , wherein the attach request is of access cloud service type.

23. The WTRU of claim 21 , wherein the WTRU attaches to the RAN node in a limited state in order to determine an operator network to use for accessing the service.

24. The WTRU of claim 23 , wherein the limited state limits at least one of an amount of time the WTRU is allowed to be attached, a destination the WTRU is allowed to access, a priority associated with requests sent by the WTRU, or bearer parameters for the WTRU.

25. The WTRU of claim 19 , wherein the service response is received in a detach message.

26. The WTRU of claim 19 , further comprising authenticating with the MNO based on the subscription information received in the service response.

27. The WTRU of claim 19 , wherein the WTRU is a light WTRU.

28. The WTRU of claim 27 , wherein the processor is configured to communicate with a cloud WTRU, wherein the cloud WTRU performs a processor or memory intense function.

29. The WTRU of claim 28 , wherein the processor or memory intense function comprises one or more of re-authentications, or temporarily storing videos.

30. The WTRU of claim 19 , wherein the service request comprises a global access point name (APN).

31. The WTRU of claim 30 , wherein the global APN comprises one or more of a network identifier, a virtual network (VN) identifier, or an operator identifier.

32. The WTRU of claim 22 , wherein the attach request comprises an indication to support dynamic virtual network (VN) extension.

33. The WTRU of claim 19 , wherein the processor is further configured to select a virtual network (VN) and indicate the selected VN in a PreAttach message.

34. The WTRU of claim 33 , wherein the PreAttach message comprises one or more of a VN capability, or a VN identifier.

35. The WTRU of claim 19 , wherein the service request comprises an access specific information of a virtual network (VN).
