Abstract
An operation method of a transmitting apparatus in a multi-connection based mobile communication system includes generating combined data by combining data and an extended information element (IE), when the data received from a serving gate way (SGW) or a core network is determined to be transmitted to a receiving apparatus; transmitting the combined data to the receiving apparatus; and receiving, from the receiving apparatus, feedback information indicating whether or not the receiving apparatus normally receives the combined data.
Claims20
An operation method of a transmitting apparatus in a multi-connection based mobile communication system, the operation method comprising:
- generating combined data by combining data and an extended information element (IE), when the data received from a serving gate way (SGW) or a core network is determined to be transmitted to a receiving apparatus;
- transmitting the combined data to the receiving apparatus;
- and
- receiving, from the receiving apparatus, feedback information indicating whether or not the receiving apparatus normally receives the combined data.
An operation method of a receiving apparatus in a multi-connection based mobile communication system, the operation method comprising:
- identifying a type of an extended information element (IE) of data received from the transmitting apparatus;
- updating feedback information indicating whether or not the data is normally received by determining whether or not a data loss exists based on a sequence number of the data;
- and
- when a data loss is not identified based on the determining, activating a next feedback transmission timer and triggering a feedback indicating whether or not the data is normally received.
A transmitting apparatus in a multi-connection based mobile communication system, the transmitting apparatus comprising at least one processor, a memory storing at least one instruction executed by the at least one processor, and a transceiver controlled by the at least one processor, wherein the at least one instruction is configured to:
- generate combined data by combining data and an extended information element (IE), when the data received from a serving gate way (SGW) or a core network is determined to be transmitted to a receiving apparatus;
- transmit the combined data to the receiving apparatus;
- and
- receive, from the receiving apparatus, feedback information indicating whether or not the receiving apparatus normally receives the combined data.
