Description

Method for controlling packet transmission of a user terminal and base station device supporting the same The present invention relates to a technology that can improve wireless resource usage efficiency by varying the transmission method according to the packet type of a user terminal in a communication system environment. In the modern era, the formation of communication channels between various electronic devices and the support of communication services between them through these channels have become commonplace. Furthermore, many users utilize mobile communication services using user terminals such as smartphones. To support communication services for user terminals, mobile communication services establish base station equipment (e.g., base station antennas and base station controllers) and, based on this, form serving cells corresponding to the communication coverage that user terminals can access. Meanwhile, the user terminal can store and install applications related to the operation of various user functions, execute a specific application in response to user input, and support user functions accordingly. Here, the user terminal can support the execution of multiple applications, perform foreground processing on the application currently used by the user (e.g., foreground application), transmit packets generated from foreground processing (e.g., foreground application packet, FAP) to a base station device in real time, and support data processing such as displaying data from foreground processing on a screen. The user terminal can perform background processing on at least one of the remaining applications among the multiple applications that are not foreground processed (e.g., background application), transmit packets from background processing (e.g., background application packet, BAP) to a base station device in real time, and, if necessary, support displaying the results of the background processing on the user terminal's display. As described above, when a packet is generated during the operation of a background application, the user terminal attempts to establish a call connection to the base station device, and after establishing the call, transmits the packets generated according to the background application operation to the base station device to support the operation of the background application. Here, even after the user terminal has completed transmitting the background application packets to the base station device, it does not release the call connection state but maintains the call connection state with the base station device for a set period of time. In this situation, even if packets are generated due to the execution of the foreground application by the user terminal, if there are many users attempting to establish a call connection or maintaining a connection due to background application packets, the foreground application packets may not be transmitted, and a delay may occur.
