Abstract

Provided are an optical relay system and a method for setting identification information of a remote device in an optical relay system. In particular, provided are an optical relay system and a method for setting identification information of a remote device in an optical relay system in which a donor device generates unique identification information of a remote device based on temporary identification information and characteristic information received from the remote device to automatically set identification information of the remote device, and as a result, the optical relay system can be normally implemented rapidly in initial installation of the optical relay system or a change of an optical relay system environment and convenience of a manager and reliability of a mobile communication service can be improved.

Claims

1. A method for setting identifiers of at least two remote devices in a distributed antenna system, the method comprising:

transmitting, by a donor device, a registration request message to the at least two remote devices;

randomly generating, by the at least two remote devices, temporary identifiers for identifying each of the at least two remote devices in the distributed antenna system in response to the registration request message;

generating, by the at least two remote devices, characteristic information for each of the at least two remote devices in response to the registration request message;

transmitting, by the at least two remote devices, the temporary identifiers and the characteristic information to the donor device;

determining, by the donor device, an order of the temporary identifiers based on the characteristic information;

generating, by the donor device, unique identifiers of the at least two remote devices; and

assigning the unique identifiers to the temporary identifiers to set identification information for each of the at least two remote devices, according to the determined order.

2. The method of claim 1, wherein the characteristic information includes a delay value of a signal transmitted and received between the donor device and the at least two remote devices.

3. The method of claim 1, wherein the characteristic information includes a frame counting value of a signal transmitted and received between the donor device and the at least two remote devices.

4. The method of claim 1, wherein the characteristic information includes a position value of a global positioning system (GPS) of a corresponding remote device or a position value of a corresponding remote device based on a base station.
