Abstract
A method and device are disclosed from the perspective of a Remote User Equipment (UE) for modifying QoS information. In one embodiment, the method includes a Remote User Equipment (UE) transmitting a first message to a Relay UE for QoS information modification, wherein the first message includes at least one QoS rule and/or at least one QoS flow description associated with a Protocol Data Unit (PDU) session.
Claims13
A method for modifying Quality of Service (QoS) information, comprising:
- a relay User Equipment (UE) establishes a Protocol Data Unit (PDU) session over a Uu leg with a network, wherein the PDU session is identified by a PDU session ID;
- the relay UE receives a Direct Communication Request message from a remote UE to establish a unicast link for a connectivity service associated with the PDU session after the PDU session has been established, wherein the Direct Communication Request message includes information indicating the connectivity service;
- the relay UE receives a Link Modification Request message from the remote UE for QoS information modification after the unicast link has been established, wherein the Link Modification Request message includes at least one QoS rule and at least one QoS flow description associated with the PDU session, and wherein each QoS rule of the at least one QoS rule includes a QoS rule identifier (QRI) and a set of packet filters;
- and
- the relay UE transmits a PDU Session Modification Request message to the network in response to reception of the Link Modification Request message from the remote UE, wherein the PDU Session Modification Request message includes the at least one QoS rule, the at least one QoS flow description, and the PDU session ID.

A relay User Equipment (UE), comprising:
- a processor;
- and
- a memory operatively coupled to the processor, wherein the processor is configured to execute a program code stored in the memory to:
- establish a Protocol Data Unit (PDU) session over a Uu leg with a network, wherein the PDU session is identified by a PDU session ID;
- receive a Direct Communication Request message from a remote UE to establish a unicast link for a connectivity service associated with the PDU session after the PDU session has been established, wherein the Direct Communication Request message includes information indicating the connectivity service;
- receive a Link Modification Request message from the remote UE for QoS information modification after the unicast link has been established, wherein the Link Modification Request message includes at least one QoS rule and at least one QoS flow description associated with the PDU session, and wherein each QoS rule of the at least one QoS rule includes a QoS rule identifier (QRI) and a set of packet filters;
- and
- transmit a PDU Session Modification Request message to the network in response to reception of the Link Modification Request message from the remote UE, wherein the PDU Session Modification Request message includes the at least one QoS rule, the at least one QoS flow description, and the PDU session ID.
