Definitions

  • the base station disclosed in the present application includes, in one embodiment, a first receiving unit, a first transmitting unit, and a second transmitting unit.
  • the first receiving unit receives information on the communication processing status of the other base station from the other base station.
  • the first transmission unit transmits a copy of the data transmitted to the terminal device to another base station.
  • the second transmission unit transmits data to the terminal device by wireless communication. Further, after the data transmission by the second transmission unit is completed, the first transmission unit sends a transmission completion notification indicating that the data transmission is completed according to the information regarding the communication processing status of the other base station. Send to the base station of.
  • step S100 PDCP Duplication is enabled between base station 20-1 and base station 20-2 (S100).
  • the processing unit when executing PDCP Duplication, the type of information notified as the load status, the conditions for notifying the load status, etc. are adjusted between the base station 20-1 and the base station 20-2.
  • FIG. 7 is a flowchart showing an example of the operation of the base station 20-1 that functions as an MCG. For example, when the adjusting unit 222 of the base station 20-1 determines that PDCP Duplication is started, the base station 20-1 starts the operation shown in this flowchart.
  • the memory 411 stores various programs, data, and the like for realizing the functions of the low layer processing unit 23, the wireless transmission unit 24, and the like.
  • the processor 412 reads a program from the memory 411 and executes the read program to realize functions such as the low layer processing unit 23 and the wireless transmission unit 24.
  • the wireless circuit 413 transmits / receives a wireless signal to / from the terminal device 30 via the antenna 25 in response to control by the processor 412.
  • the transmission unit 262 periodically transmits information regarding the communication processing status of the own device to another 20-1.
  • the other 20-1 accurately determines whether or not the transmission of the duplicate data to the terminal device 30 by the base station 20-2 is completed based on the information regarding the communication processing state of the base station 20-2. It can be judged well.
  • the transmission unit 262 transmits information regarding the communication processing state of the own device to another base station 20-1 when the communication processing state of the own device changes by a predetermined value or more. As a result, it is possible to suppress an increase in traffic between the base stations 20.
