Abstract
Disclosed is technology for applying a differential QoS, that is, service quality for each communication service by implementing a differential QoS control in a radio section in a more detailed unit without an increase in complexity and load compared to a conventional bearer-based QoS control method.
Claims12
A Base Station (BS) apparatus comprising:
- a processor;
- and
- a memory storing
- a program to be executed by the processor, and
- a mapping rule in which a first plurality of Quality of Service (QoS) parameters of a wireless network is mapped to a second plurality of QoS parameters of a service flow of a packet to be transmitted to a terminal in the wireless network, respectively,
- wherein the processor is configured to, by executing the program stored in the memory,
- identify a first QoS parameter, among the first plurality of QoS parameters, which is mapped to a second QoS parameter, among the second plurality of QoS parameters, applied to the service flow of the packet;
- and
- transmit, through the wireless network, the packet by applying the identified first QoS parameter mapped to the second QoS parameter which is applied by a core network, and
- wherein the processor is configured to transmit an Radio Resource Control (RRC) message including QoS control information to identify the first QoS parameter to the terminal, thereby allowing the terminal to transmit an uplink packet of the service flow by applying the identified first QoS level, based on the QoS control information within the RRC message.

A method of controlling a Quality of Service (QoS) in wireless network, the method executed by a Base Station (BS) apparatus comprising a processor and a memory, the method comprising:
- storing, in the memory, a mapping rule in which a first plurality of QoS parameters of the wireless network is mapped to a second plurality of QoS parameters of a service flow of a packet to be transmitted to a terminal in the wireless network, respectively;
- identifying, based on the mapping rule, a first QoS parameter, among the first plurality of QoS parameters, which is mapped to a second QoS parameter, among the second plurality of QoS parameters, applied to the service flow of the packet;
- transmitting an Radio Resource Control (RRC) message including QoS control information to identify the first QoS parameter to the terminal, thereby allowing the terminal to transmit an uplink packet of the service flow by applying the identified first QoS level, based on the QoS control information within the RRC message;
- and
- transmitting, through the wireless network, the packet by applying the identified first QoS parameter mapped to the second QoS parameter which is applied by a core network.
