For example, when new point-related information is added in the sequence of point-related information included in the route information, the UE 200 includes the added point-related information and additional indicator information whose value is true, and the reported point An RRC message containing route information without related information is sent to the base station 100 using the route information reporting procedure described above. Since the value of the additional indicator information included in the received route information is true, the base station 100 adds the received point-related information to the sequence of registered point-related information.
- an RRC message containing route information of UE 200 is transmitted from UE 200 to base station 100, and the route information includes one or more point-related information and additional indicator information.
- the route information includes one or more point-related information and additional indicator information.
- a first RRC message including first route information is transmitted, and after the transmission of the first RRC message, a second RRC message including second route information is transmitted.
- the second route information includes one or more point-related information different from any of the one or more point-related information included in the first route information.
- the entire route information for unreached routes is reported, so the route information for unreached routes among the reported route information may be reported redundantly.
- the embodiment of the present disclosure only the added point-related information can be reported to the base station 100. Therefore, by preventing redundant reporting of route information, it is possible to suppress a drop in signaling efficiency in addition of route information. As a result, waste of radio resources and power consumption for communication are suppressed.
- the UE may report additional route information when the UE reaches the end of the route indicated by the already reported route information. Conceivable. However, in this case, situations may arise where the base station does not have additional route information.
- Additional Index Information is optionally included in route information as a flag.
- additional indicator information according to embodiments of the present disclosure is not limited to this example.
- the additional indicator information indicates that one or more point-related information included in the route information is additional, and the one or more point-related information is additional may be included in the route information only if
- isAddition as shown in Figure 7 is optional and is included only when the sequence of WayPointLocations included in the FlightPathInfoReport is additional.
- the UE 200 transmits an RRC message including route information to the base station 100 (S410). For example, in the first report, since the route information to be sent is new, the UE 200 sends an RRC message containing route information without additional indicator information to the base station 100 using the above route information reporting procedure. .
- the base station 100 receives the RRC message using the routing information reporting procedure described above. Since the received route information does not include additional indicator information, the base station 100 newly registers the received point-related information.
- the UE 200 transmits an RRC message including the additional route information to the base station 100 (S420).
- UE 200 includes the added point-related information and additional indicator information when new point-related information is added in the sequence of point-related information included in the route information, and does not include the reported point-related information
- An RRC message containing route information is sent to the base station 100 using the route information reporting procedure described above.
- the base station 100 adds the received point-related information to the sequence of registered point-related information because the additional indicator information is included in the received route information.
- the additional index information indicates that one or more point-related information included in the route information is additional, and the one or more points Included in route information only if related information is additional. Therefore, by reducing the amount of data when the one or more point-related information is not added, it is possible to improve the efficiency of signaling.
