A multi-mode convergence method, a multi-mode combination method, and devices thereof are provided. The multi-mode convergence method includes the following steps. Data from multi-mode base band units (BBUs) is received and separated into downlink service data and operation maintenance data. A channel configuration is generated according to the operation maintenance data. The downlink service data of a corresponding mode is selected according to the channel configuration, and the downlink service data and the operation maintenance data are consolidated, and the consolidated data is sent to corresponding remote radio unit (RRUs). The multi-mode convergence method, the multi-mode combination method, and devices thereof are adopted, so as to accomplish functions, such as multi-mode and pseudo noise (PN) multiplexing, to decrease complexity of a multi-mode system, and provide a function of multi-mode coexistent optical fiber.

Disclosed is a method for a device without unique hardware address to obtain IP address automatically. This method comprises the steps of: the device dividing the hardware address field in the BOOTP request packet into sub-fields which are filled in by the device and the relay proxy servers forwarding the BOOTP request packet; the BOOTP server assigning an IP address to the device according to the contents in all sub-fields in the received BOOTP request packet, then generating a BOOTP response packet including the IP address of the device; and the device obtaining the IP address information from the BOOTP response packet forwarded by relay proxy servers. The content of the sub-fields can be information of interface board number, port number, slot number or Virtual Path Identifier/Virtual Channel Identifier (VPI/VCI) of an ATM Permanent Virtual Connection (PVC) of said device. Each sub-field alone cannot be a unique identifier of the device, but combination of all sub-fields can be used for identifying the device uniquely. With this method, a device can automatically obtain an IP address through BOOTP, so configuration and maintenance for devices becomes simple.
