Abstract

Claims (27)

1 . A method for use in a wireless transmit/receive unit (WTRU) comprising an edge client, the method comprising:

sending a subscription request for cell identities (IDs) associated with an Edge Data Network (EDN);

receiving policy information, in response to the subscription request sent by the WTRU, wherein the policy information comprises information to access edge data services in the EDN, wherein the policy information comprises the cell IDs associated with the EDN;

receiving security credential information, wherein the security credential information comprises an access token, wherein the security credential information is based on a WTRU identity;

determining that the WTRU is camped on a cell having a cell ID associated with the EDN; and

establishing a communication session with a node in the EDN using the security credential information.

2 . The method of claim 1 , wherein receiving policy information is in response to a request sent by the WTRU.

3 . The method of claim 1 , wherein the policy information comprises cell IDs in an EDN service area.

4 . The method of claim 1 , wherein the establishing a communication session with a node in the EDN using the security credential information comprises sending the access token to the node.

5 . The method of claim 1 , wherein the establishing a communication session with a node in the EDN further comprises:

sending a registration request to the node, wherein the registration request comprises the security credential information; and

receiving a successful registration response from the node.

6 . A wireless transmit/receive unit (WTRU) comprising an edge client, the WTRU comprising:

a receiver;

a transmitter; and

a processor, wherein:

the transmitter is configured to send a subscription request for cell identities (IDs) associated with an Edge Data Network (EDN);

the receiver is configured to receive policy information, in response to the subscription request sent by the WTRU, wherein the policy information comprises information to access edge data services in the EDN, wherein the policy information comprises the cell IDs associated with the EDN;

the receiver is further configured to receive security credential information, wherein the security credential information comprises an access token, wherein the security credential information is based on a WTRU identity;

the processor is configured to determine that the WTRU is camped on a cell having a cell ID associated with the EDN; and

the receiver and the processor are further configured to establish a communication session with a node in the EDN using the security credential information.

7 . The WTRU of claim 6 , wherein the policy information is received in response to a request sent by the WTRU.

8 . The WTRU of claim 6 , wherein the policy information comprises cell IDs in an EDN service area.

9 . The WTRU of claim 6 , wherein the receiver and the processor are further configured to send the access token to the node to establish a communication session with a node in the EDN.

10 . The WTRU of claim 6 , wherein:

the transmitter is further configured to send a registration request to the node, wherein the registration request comprises the security credential information; and

the receiver is further configured to receive a successful registration response from the node.
