Embodiment Construction

[0048]In order to make the features and advantages of the present invention clearer, the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0049] When each baseband board of a base station processes various services, it usually requires a clock synchronization signal as a reference. The clock synchronization signal includes the system clock, the frame timing period signal, the base station frame number (BFN, Basetransceiver station Frame Number), and may further include the time. information. The system clock is usually used as the clock reference source when each baseband board processes services; the frame timing period signal is usually used to indicate the frame period; the frame number is usually used to locate specific service data, and the frame timing period signal and frame number are used together to indicate the specific The location of business data. In a multi-mode base station, different sys...

Abstract

A method for transmitting clock synchronous signal supporting multimode base station includes generating system clock according to clock inputted into base station, generating synchronous burst containing synchronous information in system supported by multimode base station according to generated system clock and outputting system clock and synchronous burst to rear panel of multimode base station. The device used for realizing said method is also disclosed.

Description

technical field [0001] The present invention relates to a signal transmission technology, and in particular, to an apparatus and method for supporting the transmission of a clock synchronization signal of a multi-mode base station. Background technique [0002] In the research and development of base stations, the industry has launched models of multi-mode base stations. A multi-mode base station is a base station that can simultaneously support two or more wireless air interface standards in a base station cabinet, such as the global digital mobile phone system. Wireless air interface standards such as GSM, Global System for Mobi telecommunication, Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access), and Code Division Multiple Access 2000 (CDMA2000, Code Division Multiple Access 2000). [0003] For the transmission of the clock synchronization signal of the multimode base station, there are currently two solutions. One is that boards of d...
