SIGNAL TRANSMISSION METHOD, INTERFACE EXTENSION APPARATUS AND COMMUNICATION SYSTEM |
摘要 |
Provided are a signal transmission method, an interface extension apparatus and a communication system, which relate to the field of communications, and can solve the problem that a multi-frequency electric tilt antenna with only one AISG interface cannot simultaneously communicate with a plurality of base stations. The interface extension apparatus comprises N input interfaces and M output interfaces; the input interfaces are connected to at least one base station; the output interfaces are connected to an RET; by acquiring device information about each RET control device in a plurality of RET control devices, a proxy is respectively created for each RET control device according to the device information, there being a mapping relationship between each RET control device and a corresponding proxy; and then a control signal received from at least one base station is modulated via the proxy corresponding to the RET control device, thus sending the modulated control signal to a corresponding RET. The embodiments of the present invention are used for managing a multi-frequency electric tilt antenna by a plurality of base stations at the same time. |
