Apparatus and method for providing service network in wireless communication system
A pre-5 th -Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4 th -Generation (4G) communication system, such as Long-Term Evolution (LTE) is provided. An apparatus for providing a service network in a wireless communication system is provided. The apparatus includes a first transceiver configured to support a first radio access technology (RAT), a second transceiver configured to support a second RAT, and at least one processor configured to access a base station using the first RAT, provide a service network to at least one client device using the second RAT, and transmit at least one signal to restrict the at least one client device from entering a power saving mode, if a traffic of a client device is transferred via a low-latency service provided in the first RAT.
1. An apparatus in a wireless communication system, the apparatus comprising:
a first transceiver configured to support a first radio access technology (RAT);
a second transceiver configured to support a second RAT;
at least one processor configured to:
access a base station using the first RAT,
provide a service network to at least one client device using the second RAT,
identify a request for a low-latency service based on at least one of:
information included in a message received from the at least one client device,
a quality of service (QoS) flow identity (QFI) of a traffic for the at least one client device, or
a result of analysis of the traffic for the at least one client device, and
transmit, to the at least one client device, at least one signal to restrict the at least one client device from entering a power saving mode.
2. The apparatus of claim 1 , wherein the at least one processor is further configured to transmit a beacon signal at intervals of time shorter than a waiting time of the at least one client device for entering the power saving mode.
3. The apparatus of claim 1 ,
wherein the at least one processor is further configured to transmit a data packet periodically to the at least one client device, and
wherein the data packet comprises null data, dummy data, or data of a predetermined value.
4. The apparatus of claim 1 , wherein the at least one processor is further configured to transmit a message that indicates maintaining an active mode to the at least one client device.
5. The apparatus of claim 1 , wherein the at least one processor is further configured to decrease a maximum length of an aggregated packet in association with a packet aggregation function set for the at least one client device remaining after excluding the at least one client device from among client devices accessing the service network.
6. The apparatus of claim 5 , wherein the at least one processor is further configured to transmit a control message including an indication associated with decreasing the maximum length of the aggregated packet or a decreased maximum length value.
7. The apparatus of claim 1 , wherein the at least one processor is further configured to transmit a control message for decreasing a connection interval of periodic connection events of the at least one client device in the service network.
8. The apparatus of claim 1 , wherein the at least one processor is further configured to transmit a control message for controlling the at least one client device to perform wake-up in all periodic connection events of the at least one client device in the service network.
9. The apparatus of claim 1 , wherein the at least one processor is further configured input the traffic of the at least one client device into a queue having a highest priority among a plurality of queues.
10. The apparatus of claim 1 , wherein, if the traffic of the at least one client device is transferred via a broadband service provided in the first RAT, the at least one processor is further configured to increase a bandwidth of the client device using channel bonding.
11. The apparatus of claim 1 , wherein, if the traffic of the at least one client device is transferred via a broadband service provided in the first RAT, the at least one processor is further configured to increase a maximum length of an aggregated packet associated with a packet aggregation function set for the at least one client device.
12. A method performed by an apparatus in a wireless communication system, the method comprising:
accessing a base station using a first radio access technology (RAT);
providing a service network to at least one client device using a second RAT;
identifying a request for a low-latency service based on at least one of:
information included in a message received from the at least one client device,
a quality of service (QoS) flow identity (QFI) of a traffic for the at least one client device, or
a result of analysis of the traffic for the at least one client device; and
transmitting, to the at least one client device, at least one signal to restrict the at least one client device from entering a power saving mode.
13. The method of claim 12 , wherein the transmitting of the at least one signal comprises:
transmitting a beacon signal at intervals of time shorter than a waiting time of the at least one client device for entering the power saving mode.
14. The method of claim 12 ,
wherein the transmitting the at least one signal comprises periodically transmitting a data packet to the at least one client device, and
wherein the data packet comprises null data, dummy data, or data of a predetermined value.
15. The method of claim 12 , wherein the transmitting of the at least one signal comprises:
transmitting a message indicating maintaining of an active mode to the at least one client device.
