Embodiment
Basic thought of the present invention is: pass through the Frame of annular networking from first transmission path and the second transmission path transmitted in packets user data message between BSC and the BTS; Confirm that first transmission path is unstable; With the Frame of the user data message of first transmission path simultaneously in second transmission path; Confirm that first transmission path is stable, stop at the Frame of the user data message of second transmission path, first transmission path;
Said user data message comprises user plane message, chain of command message, and wherein, the user plane message comprises speech data etc., and the chain of command message comprises various control signalings.
Come the present invention is elaborated through specific embodiment and accompanying drawing below, as shown in Figure 1, the method for transfer of data in a kind of annular networking, concrete steps are following:
Through annular networking transmitting user data message, said transmission has the two independent data flow between BTS and the BSC, and circuit-switched data stream sends the user data message for BTS to BSC, and circuit-switched data stream sends the user data message for BSC to BTS.Wherein, in annular networking, two transmission paths are arranged between BTS and the BSC; Be used for the transmitting user data message; As shown in Figure 2, be example with BTS2, pass through the first transmission path BTS2-BTS1-BSC and the second transmission path BTS2-BTS3-BSC transmitting user data message between BTS2 and the BSC; Said grouping comprises: the user data message transmits through frame format; And each frame all is composed of sequence number; According to the type of frame number respectively in first transmission path and second transmission path; When wherein the type of frame number comprises odd-numbered frame, even frame, can the first transmission path odd-numbered frame, the second transmission path even frame; Vice versa.The user data message transmits and can realize through the agreement that real time transport protocol (RTP) or other Frames to the transmission data are composed of sequence number through the sequenced Frame.
When first transmission path is stablized, then keep first transmission path and the second transmission path transmitted in packets user data message always, when first transmission path is unstable, carry out subsequent step.
One side of receiving subscriber data message, promptly the recipient confirms that first transmission path is unstable; Frame frame-skipping like transmission; The Frame of first transmission path is passed through second transmission path simultaneously, and the Frame frame-skipping of said definite first transmission path comprises: the recipient reads the frame number of the Frame of reception, if frame number is discontinuous; The frame number that lacks the Frame of first transmission path, then the Frame frame-skipping of first transmission path; Said Frame with first transmission path comprises through second transmission path simultaneously: the recipient is passing through second transmission path to a side who sends the user data message; It is transmit leg; Add the frame-skipping sign in the Frame of transmission; Transmit leg receives the Frame that comprises the frame-skipping sign of second transmission path; When keeping the Frame of the first transmission path user data message, give the recipient through second transmission path simultaneously with the Frame of the user data message of first transmission path.
The data flow that receives the user data message of BTS transmission with BSC is an example, and BSC reads the frame number of the Frame of BTS transmission, if frame number is discontinuous; If the frame number of the Frame that receives is 1,2,4; Lack odd-numbered frame, and the first transmission path odd-numbered frame, the second transmission path even frame; Then confirm the Frame frame-skipping of first transmission path; BSC is adding the frame-skipping sign through second transmission path in the even frame of the data flow of BTS transmission user data message, BTS receives the even frame that comprises the frame-skipping sign that second transmission path sends, and the frame-skipping of reading in the even frame identifies; Keep odd-numbered frame, simultaneously in odd-numbered frame and the even frame of second transmission path to BSC transmitting user data message through the first transmission path user data message.
Said definite first transmission path is stable specifically to be comprised: the recipient receives the Frame of preset frame number N frame by first transmission path continuously, and then first transmission path is stablized, and wherein, N can be provided with as required voluntarily; The said Frame that stops first transmission path comprises through second transmission path: the recipient deletes the frame-skipping sign of the Frame that transmits to transmit leg in second transmission path; The recipient receives the Frame of second transmission path; If do not have the frame-skipping sign, stop Frame through second transmission path, first transmission path.
The data flow that receives the user data message of BTS transmission with BSC is an example; Suppose that N is 3, the first transmission path odd-numbered frame, second transmission path should only transmit even frame; But because first transmission path is unstable before, the second transmission path total data frame; If BSC receives the odd-numbered frame of 3 frames, first transmission path continuously; Confirm that then first transmission path is stable, the frame-skipping sign of BSC deletion in the even frame of second transmission path of BTS transmitting user data message, BTS receives the even frame of the user data message of second transmission path transmission; If there is not the frame-skipping sign; Then stop through the second transmission path odd-numbered frame, promptly first transmission path continues the transmission odd-numbered frame, and second transmission path only transmits even frame.
For preventing that message from repeating, BTS and BSC receive the Frame of the user data message of the other side's transmission, and the frame number of read data frame is deleted the Frame that frame number repeats.
