Abstract

Claims (23)

1 . An operating method of a policy control function (PCF) at handover from a source base station (BS) to a target BS in a mobile communication system, the method comprising:

receiving, from a session management function (SMF), a notification related to a quality of service (QoS) information selected by the target BS among alternative QoS profile (AQP) information which is supported by the target BS;

updating, a policy and charging control (PCC) rule based on the received notification; and

transmitting, to the SMF, the updated PCC rule,

wherein the QoS information selected by the target BS includes a value of at least one of a guaranteed flow bit rate (GFBR), a packet error rate (PER), or a packet delay budget (PDB).

2 . The method of claim 1 , wherein the QoS information is selected by the target BS among the AQP information based on a priority.

3 . The method of claim 1 , wherein the QoS information selected by the target BS further includes an index of the QoS information.

4 . The method of claim 1 , further comprising:

transmitting, to an application function (AF), the updated PCC rule.

5 . The method of claim 1 , wherein the target BS and a source BS perform inter-BS handover (Xn handover).

6 . A policy control function (PCF) in a mobile communication system, the PCF comprising:

a communication device;

at least one memory including instructions; and

at least one processor configured to execute the instructions to

receive, from a session management function (SMF), a notification related to a quality of service (QoS) information selected by the target BS among alternative QoS profile (AQP) information which is supported by a target base station (BS),

update, a policy and charging control (PCC) rule based on the received notification, and

transmit, to the SMF, the updated PCC rule,

wherein the QoS information selected by the target BS includes a value of at least one of a guaranteed flow bit rate (GFBR), a packet error rate (PER), or a packet delay budget (PDB).

7 . The PCF of claim 6 , wherein the QoS information is selected by the target BS among the AQP information based on a priority.

8 . The PCF of claim 6 , wherein the QoS information selected by the target BS further includes an index of the QoS information.

9 . The PCF of claim 6 , wherein the at least one processor is configured to:

transmit, to an application function (AF), the updated PCC rule.

10 . The PCF of claim 6 , wherein the target BS and a source BS perform inter-BS handover (Xn handover).
