RU apparatus, DU apparatus, communication system, communication method, and non-transitory computer-readable medium
An object of the present disclosure is to provide a remote unit (RU) apparatus that can effectively utilize statistical information of packets generated in a RU apparatus and a distributed unit (DU) apparatus that execute separated functions in a base station. A RU apparatus ( 10 ) according to the present disclosure includes: a reception unit ( 11 ) that receives a packet from a DU apparatus ( 20 ) that executes processing of a higher-level layer than a layer to be executed by the RU apparatus ( 10 ) among communication functions of a base station that are divided into a plurality of layers; and a transmission unit ( 12 ) that transmits an alarm signal to the DU apparatus ( 20 ) or a management apparatus that manages a network when statistical information regarding the received packet satisfies a predetermined criterion.
1 . A remote unit (RU) apparatus comprising:
at least one memory storing instructions, and
at least one processor configured to execute the instructions to;
receive a packet from a distributed unit (DU) apparatus configured to execute processing of a higher-level layer than a layer to be executed by a RU apparatus among communication functions of a base station that are divided into a plurality of layers;
transmit an alarm signal to the DU apparatus or a management apparatus configured to manage a network when statistical information regarding the received packet satisfies a predetermined criterion; and
transmit the alarm signal when the number of packets received in a period different from a reception window exceeds a predetermined threshold value,
wherein the reception window is a period in which the packet transmitted from the DU apparatus can be normally received.
2 . The RU apparatus according to claim 1 , wherein statistical information regarding the packet is information indicating that an abnormality occurs in communication with the DU apparatus.
3 . The RU apparatus according to claim 2 , wherein statistical information regarding the packet is information regarding a packet received in a period different from the reception window.
4 . The RU apparatus according to claim 2 , wherein statistical information regarding the packet is information regarding a packet including an error.
5 . The RU apparatus according to claim 4 , wherein the at least one processor is further configured to execute the instructions to transmit the alarm signal when the number of packets including the error or a ratio related to the number of packets including the error exceeds a predetermined threshold value.
6 . The RU apparatus according to claim 1 , wherein the at least one processor is further configured to execute the instructions to receive the predetermined criterion from the DU apparatus or the management apparatus.
7 . A distributed unit (DU) DU apparatus comprising:
at least one memory storing instructions, and
at least one processor configured to execute the instructions to;
receive a packet from a remote unite (RU) an RU apparatus configured to execute processing of a lower-level layer than a layer to be executed by a DU apparatus among communication functions of a base station that are divided into a plurality of layers; and
transmit an alarm signal to a management apparatus configured to manage a network when statistical information regarding the received packet satisfies a predetermined criterion; and
transmit the alarm signal when the number of packets received in a period different from a reception window exceeds a predetermined threshold value,
wherein the reception window is a period in which the packet transmitted from the DU apparatus can be normally received.
8 . The DU apparatus according to claim 7 , wherein statistical information regarding the packet is information indicating that an abnormality occurs in communication with the RU apparatus.
9 . The DU apparatus according to claim 8 , wherein statistical information regarding the packet is information regarding a packet received in a period different from the reception window.
10 . The DU apparatus according to claim 8 , wherein statistical information regarding the packet is information regarding a packet including an error.
11 . The DU apparatus according to claim 10 , wherein the at least one processor is further configured to execute the instructions to transmit the alarm signal when the number of packets including the error or a ratio related to the number of packets including the error exceeds a predetermined threshold value.
12 . The DU apparatus according to claim 7 , wherein the at least one processor is further configured to execute the instructions to receive the predetermined criterion from the management apparatus.
13 . The DU apparatus according to claim 7 , wherein the at least one processor is further configured to execute the instructions to transmit the predetermined criterion to the RU apparatus.
14 . A communication method being executed in a remote unit (RU) apparatus, the communication method comprising:
receiving a packet from a distributed unit (DU) apparatus configured to execute processing of a higher-level layer than a layer to be executed by a RU apparatus among communication functions of a base station that are divided into a plurality of layers; and
transmitting, when statistical information regarding the received packet satisfies a predetermined criterion, an alarm signal to the DU apparatus or a management apparatus configured to manage a network; and
transmitting the alarm signal when the number of packets received in a period different from a reception window exceeds a predetermined threshold value,
wherein the reception window is a period in which the packet transmitted from the DU apparatus can be normally received.
