Abstract
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a consumer network function (NF) in a wireless communication system is provided. The method includes transmitting, to a first user plane function (UPF), a first subscription message for event exposure service, wherein the subscription message includes an indication associated with a relocation of UPF; receiving, from the first UPF, an event notification message indicating a relocation of UPF from the first UPF to a second UPF; and determining, whether to modify a subscription for the first UPF.
Claims15
A method performed by a consumer network function (NF) in a wireless communication system, the method comprising:
- transmitting, to a first user plane function (UPF), a first subscription message for event exposure service, wherein the subscription message includes an indication associated with a relocation of UPF;
- receiving, from the first UPF, an event notification message indicating a relocation of UPF from the first UPF to a second UPF;
- and
- determining, whether to modify a subscription for the first UPF.
A method of a first user plane function (UPF) in a wireless communication system, the method comprising:
- receiving, from a consumer network function (NF), a first subscription message for event exposure service, wherein the subscription message includes an indication associated with a relocation of UPF;
- transmitting, to a session management function (SMF), a third subscription message for UPF relocation;
- receiving, from the SMF, information on a second UPF in case that the relocation of UPF is performed by the SMF;
- and
- transmitting, to the consumer NF, an event notification message indicating a relocation of UPF from the first UPF to the second UPF.
A consumer network function (NF) in a wireless communication system, the consumer network function comprising:
- a transceiver;
- and
- a controller configured to:
- transmit, to a first user plane function (UPF) via the transceiver, a first subscription message for event exposure service, wherein the subscription message includes an indication associated with a relocation of UPF,
- receive, from the first UPF via the transceiver, an event notification message indicating a relocation of UPF from the first UPF to a second UPF, and
- determine whether to modify a subscription for the first UPF.
A first user plane function (UPF) in a wireless communication system, the first UPF comprising:
- a transceiver;
- and
- a controller configured to:
- receive, from a consumer network function (NF), a first subscription message for event exposure service, wherein the subscription message includes an indication associated with a relocation of UPF,
- transmit, to a session management function (SMF), a third subscription message for UPF relocation,
- receive, from the SMF, information on a second UPF in case that the relocation of UPF is performed by the SMF, and
- transmit, to the consumer NF, an event notification message indicating a relocation of UPF from the first UPF to the second UPF.
