Abstract: A system for sharing an antenna between multiple operators is provided. The system includes a radio frequency and digital conversion unit and an active antenna. The radio frequency and digital conversion unit is configured to convert a radio frequency signal of each radio frequency module into a digital signal, and send digital signals of a same sector to an active antenna corresponding to the sector. The active antenna is configured to perform at least one of vertical beam forming processing and horizontal beam forming processing on received digital signals according to a signal transmitting parameter that is set for each operator, convert the processed digital signals into radio frequency signals, and then transmit the radio frequency signals from an air interface.

Abstract: The present invention discloses a method and network device for detecting IP address conflict. The method for detecting IP address conflict comprises: collecting all the ARP entries from a broadcasting network segment; and carrying out a data check on the ARP entries collected, and determining that there is an IP address conflicted when it is detected that there are ARP entries with the same IP address but different media access control (MAC) addresses. The network device includes a collecting module and a detecting module. The present invention may achieve the function of IP address conflict detection in a broadcasting network segment by employing one or several network devices and uses the ARP flexibly. The outer appearance of the ARP protocol is not changed, and the other devices in the broadcast network segment do not need to modify the protocol or provide special function support.
