US 12,010,644 B2 · Method and system for handling service request procedure in communication network

Abstract

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The method includes configuring, by a User Equipment (UE) (100), a Protocol Data Unit (PDU) session type as an always-ON type or a normal PDU type. Further, the method includes sending, by the UE (100), a PDU session establishment request message including the PDU session type to be the always-ON type or the normal PDU type to a network (200) during an initial PDU session establishment procedure.

Claims16

Dependent claims

A method performed by a terminal in a communication system, the method comprising:

identifying a protocol data unit (PDU) session to be established as an always-on PDU session based on an indication from an upper layer;
transmitting, to a network entity, a PDU session establishment request message including first information for requesting to establish the PDU session as the always-on PDU session;
identifying whether a user-plane resource for the always-on PDU session is established, the always-on PDU session being established based on the PDU session establishment request message;
and
transmitting, to the network entity, a service request message associated with a change of a 5G system (5GS) mobility management (5GMM) mode, in case that the user-plane resource for the always-on PDU session is not established,
wherein the service request message includes uplink data status information indicating the always-on PDU session for which data is pending.

3 more elements

A method performed by a network entity in a communication system, the method comprising:

receiving, from a terminal, a protocol data unit (PDU) session establishment request message including first information for requesting to establish the PDU session as an always-on PDU session;
and
receiving, from the terminal, a service request message associated with a change of a 5G system (5GS) mobility management (5GMM) mode, in case that a user-plane resource for the always-on PDU session is not established, the always-on PDU session being established based on the PDU session establishment request message,
wherein the service request message includes uplink data status information indicating the always-on PDU session for which data is pending.

1 more element

A terminal in a communication system, the terminal comprising:

a transceiver;
and
at least one processor coupled with the transceiver and configured to:
identify a protocol data unit (PDU) session to be established as an always-on PDU session based on an indication from an upper layer,
transmit, to a network entity, a PDU session establishment request message including first information for requesting to establish the PDU session as the always-on PDU session,
identify whether a user-plane resource for the always-on PDU session is established, the always-on PDU session being established based on the PDU session establishment request message, and
transmit, to the network entity, a service request message associated with a change of a 5G system (5GS) mobility management (5GMM) mode, in case that the user-plane resource for the always-on PDU session is not established,
wherein the service request message includes uplink data status information indicating the always-on PDU session for which data is pending.

5 more elements

A network entity in a communication system, the network entity comprising:

a transceiver;
and
at least one processor coupled with the transceiver and configured to:
receive, from a terminal, a protocol data unit (PDU) session establishment request message including first information for requesting to establish the PDU session as an always-on PDU session, and
receive, from the terminal, a service request message associated with a change of a 5G system (5GS) mobility management (5GMM) mode, in case that a user-plane resource for the always-on PDU session is not established, the always-on PDU session being established based on the PDU session establishment request message,
wherein the service request message includes uplink data status information indicating the always-on PDU session for which data is pending.
