Time division multiplexing (TDM) carries out the transmission of the different pieces of information between multiple equipment or multi-user usually on a shared link, adopt and transfer of data is divided into some time slots, each user or equipment take different time slots respectively, thus realize the peak use rate of bandwidth.
Time division multiplexing is based upon on sampling theorem basis.Sampling theorem make the baseband signal of (simulation) continuously likely replace by the sampling pulse value of discrete appearance in time.Like this, when sampling pulse occupies the short period, between sampling pulse, just leave time space, utilize this space just can transmit the sample value of other signals.Therefore, this just likely transmits several baseband signals along a channel simultaneously.
The occasion that TDM relatively commonly uses is exactly on the Stream Data Transmission for different user, specifically in application, the such as voice user of multiple 12.2K, when transmitting, different user takies different time slots, send and the corresponding different data buffering of reception different time-gap, thus realize the multiplexing of data and demultiplexing.

Embodiment
Below in conjunction with concrete preferred embodiment, the present invention program is described in detail.
The schematic flow sheet of time division multiplex channel parameter maintenance management method embodiment of the present invention has been shown in Fig. 1.As shown in Figure 1, method of the present invention comprises step:
Step S101: receive the packet that data link layer issues, enter step S102;
Step S102: the parameter of the packet that the above-mentioned data link layer received issues is resolved, if Parametric Representation its be business datum, then according to the concrete channel service processing procedure of resolving the parameter of gained and locate this business datum, enter step S103;
Step S103: TDM space-filling curve table is set up according to TDM frame transmission rule in the address of the frame originating point information of the business datum after channel Business Processing and TDM frame payload data, the address of this TDM frame payload data comprises by this TDM frame the searching mark of the position of business datum in tdm data hierarchical memory, enters step S104;
Step S104: the address of reading TDM frame payload data from TDM space-filling curve table, searches according to the address of TDM frame payload data and reads TDM frame payload data, being encapsulated as TDM frame, entering step S105 from tdm data hierarchical memory;
Step S105: read frame originating point information from TDM space-filling curve table, after the TDM frame of frame originating point information and this encapsulation is encapsulated as TDM business data packet, is saved in and sends in buffering area, enter step S106;
Step S106; And according to the priority of round-robin, timing is taken out TDM business data packet and is sent from transmission buffering area.
According to the invention described above scheme, be by channel service process after the frame originating point information of business datum and the address of TDM frame payload data set up TDM space-filling curve table, and the TDM frame payload data after channel service process carries out classification storage according to the transmission cycle of this channel data, when sending data, from space-filling curve table, retrieve according to the sequencing of timeslice the label needing the data sent immediately, and from tdm data hierarchical memory, extract corresponding TDM frame payload data according to label and to package transmission, thus achieve the flexible allocation of memory space in time division multiplex channel Business Processing, make the maintenance of parameter more efficient, decrease the memory space that each TDM service frame takies, can meet consumers' demand to greatest extent, effectively save cost.
In order to process the packet that the data link layer received issues in time, and the packet received can not be lost below, therefore, before above-mentioned packet is resolved, can also step be comprised:
The form adopting round-robin queue to read data carries out buffer memory to the packet that the data link layer received issues.
Here buffer memory can be carry out buffered by arranging cyclic buffer.By the setting of cyclic buffer, not only can guarantee that received packet can take out timely, can not cause the loss of the packet received below, and data receiver can be kept apart with data processing.By the mode that data receiver and circular buffering are arranged in pairs or groups mutually, the throughput of data receiver can also be improved, guarantee the reliability of DRP data reception process.
Illustrate in Fig. 2 that one is carried out the concrete example of circular buffer to the packet received.In shown in Fig. 2, be provided with the buffering area of predetermined memory space based on interface protocol, and with the form that round-robin queue reads and writes data, data storage management carried out to this buffering area.
As shown in Figure 2, after receiving the packet 1 that data link layer issues, this packet 1 is broken down into data block 1 ~ 4, because now cyclic buffer is not yet brought into use, do not store any data, this data block 1 ~ 4 first address of self-loopa buffering area will start unloading in cyclic buffer, makes the initial write address of effective memory space of cyclic buffer change into the next address that data block 4 takies address.Subsequently, data block 1 ~ 4 is read out and processes, and the space taken before discharging it, become effective memory space, but initial write address does not change.
When receiving the packet 1 ' that data link layer issues, this packet 1 ' is broken down into data block 1 ' ~ 2 ', and store from the initial write address of effective memory space of cyclic buffer, because data block 1 ' is only enough left in the free storage after the initial write address of now cyclic buffer, behind free storage then after data block 1 ' is stored in initial write address, data block 2 ' stores from the first address of cyclic buffer.After storage, the initial write address of effective memory space of cyclic buffer changes into the next address of the shared address of data block 2 ', to store subsequently received data block.Other do not repeat them here by that analogy.
In addition, after the parameter of above-mentioned packet is resolved, step can also be comprised: the parameter of resolving gained is verified, to guarantee correctness, the legitimacy of the parameter of gained.
The schematic diagram of resolving the parameter of packet has been shown in Fig. 3.When carrying out Data Analysis, from cyclic buffer, first extract the packet based on interface protocol, resolve the parameter of each packet, and the correctness of parameter, legitimacy are verified, when verify by: if determine that this packet is the message such as configuration querying according to parameter, then initialization or the system of renewal relevant parameter, system status parameters packing is reported; If determine that this packet is the business datum that upper strata issues according to parameter, then locate the concrete channel service processing procedure of this business datum according to the parameter of resolving gained.
In a practical situation, a packet may have multiple message body, therefore, when above-mentioned parsing, can be respectively each message body is resolved, to have N number of message body in a packet, concrete resolving can be: after extract packet from cyclic buffer, resolve the packet header of this packet, then the single message body parameter in this packet is resolved, after parsing, to the correctness of this single message body parameter, legitimacy judges, if judge by, this single message body is transferred to next resume module, carry out follow-up processing procedure, and the single message body parameter of the next one is verified, otherwise then abandon this message body, reported data link layer mistake, and the single message body parameter of the next one is verified, until all verified complete to the N number of single message body parameter in this packet.
Subsequently, space-filling curve table is set up according to TDM frame transmission rule in the address of the frame originating point information of business datum after channel Business Processing and TDM frame payload data, wherein, the searching mark of comprise to by TDM frame in the address of the TDM frame payload data here position of business datum in tdm data hierarchical memory.
Wherein, the principle of grading of tdm data hierarchical memory can be: by all kinds of channel service, multiple TDM frames of being formed after treatment of its initial data are sent required time TDM business that the is identical or Traffic Channel of time difference in setting range and are classified as same one-level.This considers, in TDM Business Processing, the raw information of different channel types is different having transmitted the required time after physical layer process, and therefore memory space is also different.The present invention based on the inconsistency of the dynamic memory space size taken in this different channels Business Processing transmitting-receiving process, proposes above-mentioned classification memory allocation flexibly method just.
For above-mentioned TDM space-filling curve table, above-mentioned tdm data hierarchical memory, the mode of circular linked list all can be adopted to carry out mapping management, thus, for different business, more can increase or reduce chained list progression flexibly, greatly improve memory space utilance, reduce the complexity of data storage procedure and storage administration.
The concrete example that a TDM business maps and classification stores has been shown in Fig. 4, as shown in Figure 4, TDM space-filling curve table is associated with tdm data hierarchical memory, when needs carry out transmission data, from TDM space-filling curve table, the address of TDM frame payload data is inquired by the frame originating point information of business datum, determine the position of TDM frame payload data in tdm data hierarchical memory, then from tdm data hierarchical memory, corresponding TDM frame payload data is taken out according to the address of the TDM frame payload data inquired, send after forming TDM radio frames with frame originating point information.
A concrete example of TDM space-filling curve table has been shown in Fig. 5.As shown in Figure 5, this TDM space-filling curve table combines with channel and combines, and this TDM space-filling curve table is made up of all kinds of parameter.In the Traffic Channel of each time slot, the parameter of each burst sends sequence according to the frame of regulation and maps.Wherein, carrier level parameter is the total property parameters of time-multiplexed all eight time-division multiplex slots in radiofrequency signal; Timeslot-level parameter is the property parameters that all bursts of a time slot have, and is released or upgrades in reconfiguration course at this time slot services; Burst level parameter is the exclusive parameter of a burst, comprising the station location marker of data in TDM service classification memory module of this burst.The mapping table of single time slot with N number of Burst information unit for loop cycle.
For gsm system, the design of the GSM channel parameter mapping table of gsm system and management are based on the structure shown in Fig. 5, and this structural design thought is with the least possible internal memory, complete again parameter and the data management of miscellaneous service very easily simultaneously.First, the parameter that will relate to is classified according to the frequent degree upgraded, concrete classification schematic diagram is as shown in the hierarchy mapping figure in Fig. 5 shown in (HierarchicalMapping), carrier level (the Carrier in diagram can be divided into, as C0 carrier identification, C0 carrier power, BCC etc.), timeslot-level (the Timeslot in diagram, as channel composite type, training sequence, encryption type, frequency hopping identifies, performance number etc.) and the burst of pulses level (Burstinformation in diagram, as type of service, payload data address etc.).Secondly, the memory space upgraded the most frequently needed for burst of pulses level parameter is maximum, for different business as TCH voice service and TCH data service also have very large difference.So also must treat with a certain discrimination, otherwise the significant wastage of memory space can be caused.Specific practice designs according to the most conventional voice service, and other business that cannot meet the demands then increase secondary chained list on this basis and expanded.
A concrete example of tdm data hierarchical memory has been shown in Fig. 6.For gsm system, in the process of GSM base station physical layer chnnel coding, the raw information of different channel types is different having transmitted the required time after physical layer process, and therefore memory space is also different.And the size of the decoding input data buffering area of different channels type also can be different because of the difference of channel type.Based on the inconsistency of the dynamic memory space size in this different channels Business Processing transmitting-receiving process, in the concrete example shown in Fig. 6, all kinds of for GSM channel is made the data storage cell after chnnel coding and is divided into 5 grades.
The first order is the M1 in Fig. 6: such as synchronizing channel carries the information of the frame synchronization information (tdma frame number) of MS and the identification code (BSIC) of BTS, as down channel, send at No. 0 time slot of the down link of BCCH carrier frequency, the transmission of the identification code of a complete MS frame synchronization information and BTS needs a burst to have passed, so 0.557ms can pass above information.
The second level is the M2 in Fig. 6: such as a LAPDm frame is 23Byte, and the useful information closing 184bit, SACCH is also 184bit.But this is raw information, after chnnel coding, just become 456bit.Each burst can transmit 57 × 2=114bit.So 456bit just needs 4 bursts just can complete; Have 25 TCH frames and 1 SACCH frame in every 26 frames, the time that so will pass 4 SACCH frames needs altogether is 4 × 26 × 4.615ms=480ms, that is, 480ms could pass the effective information of 184bit.
The third level is the M3 in Fig. 6.Such as in the control channel business of 51 multi-frames, raw information has become 456bit after chnnel coding.Each burst can transmit 114bit, then 456bit needs 4 bursts just can complete.In 51 multi-frames, the transmission of these 4 bursts is frame number continuous print, and pass this time required for 4 bursts is 4 × 4.615ms=18.46ms.
The fourth stage is the M4 in Fig. 6.Such as in TCH speech business.The raw information of TCH/FS with TCH/HS has become 456bit and 228bit respectively after chnnel coding.Each burst can transmit 57bit.So 456bit and 228bit needs 8 and 4 bursts just can complete respectively.The time passed required for TCH/FS and TCH/HS mono-piece of speech frame is 8 × 4.615ms=36.92ms and 4 × 4.615ms=18.46ms respectively.
Level V is the M5 in Fig. 6.Such as in TCH data service, the raw information of TCH/F14.4, TCH/F9.6, TCH/F4.8, TCH/H4.8, TCH/H2.4 has become 456bit after chnnel coding.Each burst can not transmit 6bit, 12bit, 18bit, 24bit not etc.This 456bit needs 22 bursts just can complete.The time that having passed these 22 TCH Frames (centre is also inserted with a SACCH frame or idle frame) needs altogether is 23 × 4.615ms=106.145ms.
Wherein, in TDM service classification memory the structure of memory cell M1 at different levels ~ M5 with to carry out the structure of circular buffer to the packet received in Fig. 2 consistent.
Establish space-filling curve table and achieve classification store after, when sending data, concrete send mode can be: the address of reading TDM frame payload data from TDM business mapping table, according to the address search tdm data hierarchical memory of this TDM frame payload data, therefrom read out corresponding TDM frame payload data, and be encapsulated as TDM frame; And TDM frame originating point information is read from TDM space-filling curve table, after the TDM frame group bag after TDM frame originating point information and encapsulation is encapsulated as TDM business data packet, is saved in and sends in buffering area.Then, according to timeslice sequencing, timing sends take out TDM business data packet from transmission buffering area after, and reporting system does next step scheduling.
