Apparatus and method for configuring backhaul link in wireless communication system
The present disclosure relates to 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). A network providing device includes at least one transceiver, and at least one processor operatively coupled with the at least one transceiver. The at least one processor is configured to acquire a measurement result of a signal transmitted by a first cellular network, and transmit, to a router, a control message for setting a router to access a network identified on the basis of the measurement result. The network comprises at least one of the first cellular network and a second cellular network.
1. A method performed by a network providing device, the method comprising:
acquiring a measurement result of a signal transmitted by a first base station of a first cellular network accessible by a router via the network providing device over a first backhaul link, wherein the router is connected to one or more user equipment (UE);
determining whether the measurement result is less than a channel quality threshold;
obtaining a link quality between the network providing device and the router;
determining whether to switch network access to a second base station of a second cellular network over a second backhaul link, which is different from the first cellular network, identified based on the measurement result and the link quality; and
transmitting, to the router, a first control message for configuring the router to switch network access to the second cellular network over the second backhaul link, based on a result of the determination.
2. The method of claim 1 , further comprising:
in case that measurement result is greater than the channel quality threshold, and the link quality is greater than a link quality threshold,
generating a second control message for configuring the router to access the first cellular network over the first backhaul link; and
transmitting the second control message.
3. The method of claim 1 ,
wherein the network providing device is customer-premises equipment (CPE) supporting the first cellular network,
wherein the first cellular network is a new radio (NR) based network, and
wherein the second cellular network is a long term evolution (LTE) based network.
4. A network providing device comprising:
at least one transceiver; and
at least one processor operatively coupled with the at least one transceiver,
wherein the at least one processor is configured to:
acquire a measurement result of a signal transmitted by a first base station of a first cellular network accessible by a router via the network providing device over a first backhaul link, wherein the router is connected to one or more user equipment (UE);
determine whether the measurement result is less than a channel quality threshold;
obtain a link quality between the network providing device and the router;
determine whether to switch network access to a second base station of a second cellular network over a second backhaul link, which is different from the first cellular network, identified based on the measurement result and the link quality; and
transmit, to the router, a first control message for setting a router to switch network access to the second cellular network over the second backhaul link, based on a result of the determination.
5. The network providing device of claim 4 , wherein the at least one processor is configured to:
in case that the measurement result is greater than the channel quality threshold, and the link quality is greater than a link quality threshold, generate a second control message for setting the router to access the first cellular network over the first backhaul link; and
transmit the second control message.
6. The network providing device of claim 4 ,
wherein the network providing device is a customer-premises equipment (CPE) supporting the first cellular network,
wherein the first cellular network is a new radio (NR) based network, and
wherein the second cellular network is a long term evolution (LTE) based network.
