Abstract
In one method, a session management function (SMF) provides a policy control function (PCF) with a remote WTRU's information using a PDU session of a relay WTRU and when there is any update on the remote WTRU's information for accessing the PDU session of relay WTRU, e.g. DN authorization info from DN-AAA after successful authorization, the SMF informs the updated information to PCF. Based on the received information from SMF, the PCF manages PDU session context per Remote WTRU. The PCF may update the remote WTRU's subscription data to indicate the PCF for the PDU session via the relay WTRU or register with a binding support function (BSF) PCF information relating to the remote WTRU. Additional embodiments are disclosed.
Claims16
A method for a session management function (SMF), the method comprising:
- sending, to a policy control function (PCF), a first context update for a packet data unit (PDU) session with a relay wireless transmit receive unit (WTRU), the first context update including a remote user identity for a remote WTRU;
- receiving, from the PCF, an indication the remote WTRU requires data network (DN) authorization including a user ID for a proximity services (ProSe) secondary authentication (SA) procedure between the remote WTRU and a DN authorization server;
- and
- initiating the ProSe SA procedure for the remote WTRU based on the user ID, in response to the indication received from the PCF.
A network node including a session management function (SMF), the network node comprising:
- a transceiver and a processor operatively coupled with the transceiver, the transceiver and processor configured to:
- send, to a policy control function (PCF), a first context update for a packet data unit (PDU) session with a relay wireless transmit receive unit (WTRU), the first context update including a remote user identity for a remote WTRU;
- receive, from the PCF, an indication the remote WTRU requires data network (DN) authorization including a user ID for a proximity services (ProSe) secondary authentication (SA) procedure between the remote WTRU and a DN authorization server;
- and
- initiate the ProSe SA procedure for the remote WTRU based on the user ID, in response to the indication received from the PCF.
A method for a policy control function (PCF), the method comprising:
- receiving, from a session management function (SMF), a first context update for a packet data unit (PDU) session with a relay wireless transmit receive unit (WTRU), the first context update including a remote user identity for a remote WTRU;
- storing a PDU session context of the remote WTRU including indication the remote WTRU is using a data network name (DNN)-identified PDU session via the relay WTRU;
- and
- sending, to the SMF, an indication the remote WTRU requires data network (DN) authorization including a user ID for a proximity services (ProSe) secondary authentication (SA) procedure between the remote WTRU and a DN authorization server.
