US 10,542,490 B2 · Method and apparatus for controlling communication of a portable terminal in a wireless communication system

Abstract

The present disclosure relates to a 5th Generation (5G) or pre-5G communication system supporting a higher data transfer rate after a 4th Generation (4G) communication system such as Long Term Evolution (LTE). In particular, a method and an apparatus for controlling communication of a terminal in a wireless communication system are provided. The method includes receiving information regarding an operation of a second system by using a first communication module configured to support a first system and controlling an activation state of a second communication module configured to support the second system, based on the information regarding the operation of the second system.

Dependent claims

A method of a terminal supporting multi-radio access technologies (multi-RAT) in a wireless communication system, the method comprising:

receiving, from a base station through a first RAT, a control signal to stop receiving packet data convergence protocol (PDCP) data to be received from an access node through a second RAT by deactivation of the second RAT, if the PDCP data to be received from the access node is not detected by the base station during a preset time period from a time point when the PDCP data to be received from the access node is transmitted from the base station to the access node for transmission to the terminal;
transmitting, to the base station through the first RAT in response to the control signal to stop receiving the PDCP data to be received from the access node, a first sequence number of PDCP data which the terminal has last received from the access node;
and
receiving, from the base station through the first RAT, PDCP data with a second sequence number that is higher than the first sequence number.

An apparatus of a terminal supporting multi-radio access technologies (multi-RAT) in a wireless communication system, the apparatus comprising:

a first transceiver configured to support a first RAT;
a second transceiver configured to support a second RAT;
and
at least one processor configured to:
receive, from a base station through the first RAT, a control signal to stop receiving packet data convergence protocol (PDCP) data to be received from an access node through the second RAT by deactivation of the second RAT, if the PDCP data to be received from the access node is not detected by the base station during a preset time period from a time point when the PDCP data to be received from the access node is transmitted from the base station to the access node for transmission to the terminal,
transmit, to the base station through the first RAT in response to the control signal to stop receiving the PDCP data to be received from the access node, a first sequence number of PDCP data which the terminal has last received from the access node, and
receive, from the base station through the first RAT, PDCP data with a second sequence number that is higher than the first sequence number.
