The present invention relates to a method for supporting communications of heterogeneous meters to prevent various kinds of metering information of a predetermined customer from being leaked. According to the present invention, the method supports communications of heterogeneous meters in a remote metering system including a device language message specification (DLMS) server as a meter for measuring a plurality of heterogeneous energies, a DLMS client as a gateway, and a DLMS third party as a metering server for each energy. The method comprises the following steps: performing application coupling between all DLMS servers and DLMS clients; sharing a shared key between all the DLMS servers and DLMS clients; sharing a shared key between all the DLMS servers and DLMS third parties; when the DLMS third party requests metering data to a predetermined DLMS server through the DLMS client, encapsulating and transmitting, by the DLMS client, a metering data request message to the corresponding predetermined DLMS server; and when the corresponding predetermined DLMS server responds to the metering data, encapsulating and transmitting, by the DLMS client, the metering data response message to the corresponding predetermined DLMS third party. 본 발명은 이종 계량기의 통신을 지원하는 방법에 관한 것으로, 복수의 이종 에너지 계량을 위한 계량기인 DLMS(Device Language Message Specification) 서버, 게이트웨이인 DLMS 클라이언트, 및 에너지별 검침서버인 DLMS 서드파티를 포함하는 원격검침 시스템에서 이종 계량기의 통신을 지원하는 방법에 있어서, 상기 모든 DLMS 서버와 DLMS 클라이언트간 응용 결합을 수행하는 단계; 상기 모든 DLMS 서버와 DLMS 클라이언트간 공유키를 공유하는 단계; 상기 모든 DLMS 서버와 DLMS 서드파티간 공유키를 공유하는 단계; 상기 DLMS 서드파티가 상기 DLMS 클라이언트를 통해 특정 DLMS 서버에 검침 데이터를 요청할 경우, 상기 DLMS 클라이언트가 검침 데이터 요청 메시지를 캡슐화한 후 해당하는 특정 DLMS 서버에 전송하는 단계; 및 상기 해당하는 특정 DLMS 서버가 검침 데이터를 응답할 경우, 상기 DLMS 클라이언트가 검침 데이터 응답 메시지를 캡슐화(encapsulation)한 후 해당하는 특정 DLMS 서드파티에 전송하는 단계;를 포함한다.
