Abstract:
1. A method for transferring multi-standard radio Service data, comprising: designing a radio service frame timing mechanism and a rule of filling In-phase/Quadrature (IQ) data for a plurality of wireless communication standards; configuring frame timing information and methods of mapping IQ containers corresponding to a plurality of radio services, according to the designed, radio service frame timing mechanism and the rule of filling IQ data for the plurality of wireless communication standards, by means of signaling or control words, through a control channel of a Common Public Radio Interface (CPRI); and transferring multi-standard radio service data according to the configured frame timing information and the methods of mapping IQ containers corresponding to the plurality of radio services; wherein the designing of the radio service frame timing mechanism and the rule of filling IQ data comprises: determining uniform timing information which is a common multiple period equal to an integer N multiple of the length of a basic frame of the CPRI and an integer M multiple of the length of a radio service frame; designing the radio service frame timing mechanism to achieve synchronization alignment between the radio service frame and the basic frame of the CPRI, according to the common multiple period; and designing the rule of filling IQ data by taking consecutive N basic frames as a basic frame set to bear the IQ data of every M radio service frames with each basic frame set, according to the common multiple period; wherein the transferring multi-standard radio service data comprises: transmitting, by a sender, the uniform timing information, and assembling and transmitting the multi-standard radio service data according to the configured frame timing information and the method of mapping IQ containers; and recovering, by a receiver, respectively the received uniform timing information, frame timing information and IQ data, and obtaining frame timing information and frame data of the radio service frames; and wherein the transferring multi-standard radio service data further comprising: when applying a cascade connection of radio equipments, transparently transferring, between an upper-stage radio equipment and a lower-stage radio equipment or between a radio equipment and a radio equipment controller, IQ data of the radio service frames borne by the radio equipments or the radio equipment controllers by transferring basic frame sets via the CPRI.
