Embodiment
Below in conjunction with drawings and Examples technical scheme of the present invention is described in detail.
Fig. 1 is the schematic diagram of the signaling acquisition device of the embodiment of the invention, and as shown in Figure 1, the signaling acquisition device of present embodiment comprises the E1/T1 Interface module, time gas exchange module, data acquisition module and clock processing module.
The E1/T1 Interface module comprises the E1/T1 Interface chip and adds the E1/T1 Interface protective circuit; be mainly used in and finish the conversion of E1/T1 signaling link code type; the E1/T1 Interface chip realizes that the coded format with input is HDB3 (High Density Bipolar 3; High Density Bipolar 3) or AMI (AlternateMark Inversion; bipolarity replaces inversion code) convert NRZ (No Return Zero to; nonreturn to zero code) highway signal (the highway signal is a kind of serial signal) is transferred to the time gas exchange module with the highway signal of NRZ nonreturn to zero code.
The clock processing module is used for extracting the frame synchronization clock signal of a certain input E1/T1 signal, giving clock chip carries out phase-locked, thereby produce a series of system works clocks, as 16MHz, 8MHz, 8KHz etc. distribute E1/T1 Interface module, time gas exchange module and data acquisition module respectively with the corresponding work clock.
The time gas exchange module comprises the time gas exchange chip, and wherein switching matrix of configuration can make some time slot of the E1/T1 signal of arbitrary input output in the particular time-slot of E1/T1 signal of arbitrary output.
The time gas exchange module is carried out scanning analysis with each bar highway signal replication to data acquisition module successively, obtain the start bit and the information such as stop bit and signaling rate of signaling type, significant bit, identify signalling time slot number and signaling rate in this input E1/T1 signal, and note.All done after such scanning at all highway signals, just obtained the signaling information of all input E1/T1 signals.Data acquisition module returns to the time gas exchange module with scanning result then, the time gas exchange module is carried out the configuration of switching matrix according to these signaling informations, will the signalling time slot concentrate by certain rule and to converge in a few the highway signals, for example can the time slot of phase same rate be put together or the signalling time slot be restrained, again these several highway signal replications are outputed to data acquisition module and carry out data acquisition according to effective bit.
Data acquisition module can be made up of microprocessor module, mainly carries out data content identification and data content and extracts, and the data that collect are exported by Ethernet interface.With typical PowerPC series processors is example, adopt TDM (the Time-division multiplexed of chip internal, time division multiplexing), SI (Serial Interface, serial line interface) and QMC (QUICC Multichannel Controller, Multi Channel Controller) realize data acquisition function.
As shown in Figure 2, data acquisition module is made up of TDM interface, SI serial line interface, QMC and data processing unit.When on the TDM interface that one by one input highway handshaking is outputed to data acquisition module by the time gas exchange module, SIRAM is routed to corresponding SCCx (Serial Communications Controllers with some bit in the serial data stream by programming, serial communication control) or SMC (Serial Management Controllers, Serial Management Controller), the effective bit in configuration TSA (Time-Slot Assigner) the time slot allocation table is realized the identification of data.The transformation of data of SCCx or SMC serial originally is parallel data and is delivered to QMC, contain HDLC (High Level Data Link Control among the QMC, High-Level Data Link Control) framer is carried out to the frame processing to data, has only the data that satisfy the HDLC agreement could form the HDLC data.Because the data of input may be types such as 64Kbps, 32Kbps, 16Kbps, when carrying out time slot scanning, by changing the configuration of SIRAM and TSA table, travel through all signaling types, when having only data and configuration adaptive fully, could correctly form the HDLC frame, carry out time slot scanning according to this characteristic.All input highway signals just can obtain the information such as start bit, stop bit and signaling rate of signaling type, significant bit through after the time slot scanning.Conversely, result according to time slot scanning disposes time gas exchange matrix and SIRAM and TSA, just can carry out data acquisition, the data that collect are put in the buffering area of appointment, carry out data processing then, comprise and beat timestamp, data filter and data are formed processing such as IP bag, export by Ethernet interface then.
If the acquisition channel of data acquisition module also has remaining acquisition channel except that the 2nd highway signal that is used to gather input, then when carrying out data acquisition, utilize these remaining acquisition channels that the one highway signal of input is carried out time slot scanning, whether the one highway signal data of scanning input changes, vicissitudinous words, then upgrade time gas exchange matrix and SIRAM and TSA immediately, carry out the renewal of data, accomplish real-time tracking and processing.
If the signalling time slot of input surpasses the load of data acquisition module, then can converge to unnecessary time gas exchange on certain one or several highway signal and export, adopt the information of these time slots the mode of HDLC packet to send by data acquisition module agreement time slot then, the collecting device of informing next stage is informed the user simultaneously and these unnecessary output E1/T1 to make things convenient for its collection.
If the irregular variation of signalling time slot of input E1/T1, such as ABIS (interface between base transceiver station and the base station controller) signaling, then can reserve the work of several passage specializes above-mentioned " scanning configuration ", that is to say, when gathering, duplicate a piece of data and give the passage of reserving, carry out data analysis and processing.If signaling rate that is scanned or timeslot number are compared with analysis result before and are changed, then upgrade the exchange configuration in signalling time slot by the time gas exchange module, accomplish real-time tracking and processing.That is to say that this signaling acquisition device can be followed the tracks of the variation of data on the E1/T1 link automatically, can very strong flexibility and practical value be arranged surpassing that part of signalling time slot exchanging convergence output that will surpass under the situation of this device acquisition capacity again.
Fig. 3 is the flow chart according to the method for the signal collecting of the embodiment of the invention, is applied to comprise the E1/T1 Interface module, in the signaling acquisition device of time gas exchange module and data acquisition module.As shown in Figure 3, the signal collecting method of present embodiment comprises following step:
