Abstract: Disclosed is a random access method and device. A terminal generates a random number for a random access, and compares the random number and a setting value. When the random number is included in the setting value, the terminal transmits a preamble for a random access to a base station and attempts a random access.

Abstract: A base station infers a random access failure rate depending on a random access collision of terminals performing random access and controls a random access opportunity of a terminal that fails the random access by using the random access failure rate of each terminal. Also, information for the controlled random access opportunity is transmitted to the terminal that fails the random access.

Abstract: Methods for flow control in a network are disclosed. In a dual connectivity network environment where a master base station and a secondary base station exist, an operation method of a master base station may comprise transmitting a data frame including a plurality of data packets to a secondary base station; receiving, from the secondary base station, a delivery status frame requesting retransmission of error data packet among the plurality of data packets; and retransmitting the error data packet indicated by the delivery status frame to the secondary base station. Therefore, network performance can be enhanced.

Abstract: Provided is a method for resuming, by a first base station, a radio resource control (RRC) connection suspended by a second base station. The first base station receives an RRC connection resume request message including a first identifier and a resume identifier for identifying the second base station from a terminal. The first base station identifies the second base station using the first identifier. Further, the first base station acquires access stratum (AS) context information matching the resume identifier from the second base station, using the resume identifier.

Abstract: The present invention relates to a automotive partial networking apparatus and method, which operate or terminate only a specific electronic control unit corresponding to a service currently being provided in a vehicle network composed of a plurality of electronic control units. In the automotive partial networking method, a automotive partial networking apparatus receives a partial networking-only Controller Area Network (CAN) frame from outside of the apparatus. A partial network table is searched based on the CAN frame, and then a CAN identification (ID) is searched for. A partial networking-only CAN frame is generated using the CAN ID. Partial networking is performed by transferring the generated partial networking-only CAN frame to at least one electronic control unit corresponding to a vehicle service.
