In actual applications, embedded VoIP system of the present invention as shown in Figure 1, the voice quality of integrated native system and data safe processing module (FastCache), the message of receiving from network side carries out mistake to be processed, loss of voice remedies, and the Reseal message is sent to DSP and processes.
Voice message at first enters the bag correction verification module in the FastCache module, carries out the RTP packet filtering, and this processes similar with packet filtering in the computer network, filter mainly for the RTP message.The voice message mistake is processed, and is that unusual bag or normal bag are investigated again mainly for the RTP message through the bag verification, and the RTP message that again filters out correct format is used for transmission.Loss of voice remedies, the algorithm that relates to also is difficult point of the present invention, do an endless loop in this module, main constantly the detection in communication process after RTP message dropping and the time-delay, is reflected to the user and is exactly that voice quality compares is relatively poor there, perhaps sound is unintelligible, here the algorithm of design can automatic Sampling network connection, causes unsharp processing of conversing from rtp streaming amount statistics or according to message is imperfect, can analyze and process by this algorithm.
Message again divides to install to and sends to DSP and process, and all is a forwarding module for the message of previous processed okay here.The unified accurate and safe message of process FastCache module that sends is to the bottom resume module.
The poor main cause of voice quality is the delay of packet and loses that the slow reason of this similar running car is that the highway traffic congestion is the same.The poor reason of voice quality is not one, and a kind of method also can't address this problem.Reason wherein may be that ISP has limited bandwidth, and the speed of data traffic has been subject to the impact of fire compartment wall and address transition mechanism, or phone has occured to conflict with the video file that neighbours are downloading.The early purchasers of VoIP may be ready to accept second-rate VoIP conversation, but main flow consumer and corporate client are unwilling.Service quality is extremely important, wishes that the VoIP provider that obtains more revenue need to provide uniform high-quality to experience.Purpose of the present invention is exactly to utilize FastCache module newly-increased in the system to address this problem.
This is applied in the voice quality and data safety management module in the VoIP field of embedded technology, described FastCache mainly is integrated in the voip phone system, the invention process can be used as a kind of scheme that the product design of reasonable terminal voice is adopted on the VoIP system under the improvement project.
When beginning a RTP session, application program will use two ports: give RTP for one, give RTCP for one.RTP itself can not provide reliable transfer mechanism for transmitting in order packet, and flow control or congestion control are not provided yet, and it relies on RTCP that these services are provided.Periodically between the session of RTP send a little RTCP groupings and be used for the functions such as Monitoring Service quality and exchange session user profile.Contain the quantity of the own packet that sends, the statistics such as quantity of missing data grouping in the RTCP grouping.Therefore, server can utilize these information dynamically to change transmission rate, even changes PT Payload Type.RTP and RTCP are used, and are generally used on the UDP, and they can make the efficiency of transmission optimization with effective feedback and minimum expense, thereby are particularly suitable for the real time data on the transport network.According to the transfer of data feedback information between the user, can formulate the strategy of flow control, and session subscriber information is mutual, can formulate the strategy of session control.FastCache realizes session control as a kind of reasonable selection scheme so, and the session message dropping remedies, and mails to the correct process of processing of DSP after the session updates.
In order to realize this FastCache function, the present invention comprises following major part substantially:
1, embedded VoIP system, model is on the general frame of VoIP system, VoIP mainly comprises (CallClient module, SIP/H248stack, bottom layer treatment module (ENDPT), the RTP module, poll dislodging machine event module, poll bottom media bag module, FastCache module), these all are the systems soft ware parts, and hardware components mainly is that voice relevant DSP, SLIC add peripheral circuit.
2, the corresponding readjustment of the startup of CallClient resume module H248 protocol stack and registration is responsible for initialization, and the startup of transmitting-receiving media bag task, event detection task of endpoint.
3, protocol stack SIP/H248 module is the nucleus module of H248 protocol stack, the transmitting-receiving of responsible protocol package and re-transmission etc.
4, the bottom module is the bottom layer treatment module, Treated Base reporting events, media processing, sound broadcast etc.
5, the RTP module just is responsible for the reception of RTP bag, and passes to DSP.
6, bottom dislodging machine event polling is polled to after the event and puts into formation, and the task taking-up event from formation in the CallClient module waited for is carried out the upper strata and processed.
7, poll bottom media message module, and send by SOCKETAPI.
8, the FastCache module is mainly processed the media message that sends over from SOCKETAPI, because RTP is carried on the UDP(insecure protocol) upper transmission, may lose message, the error control aspect affects normal voice call, here process turnover RTP message with this module, finally guarantee the security control of speech data and the improvement of voice quality aspect.
The FastCache Model Implement adopts the embedded Linux platform, mainly comprises three parts, can be with reference to shown in Figure 2:
1, running software may further comprise the steps:
1.1 process initiation, initialization, whole system enters idle condition (FastCache also finishes initialization), comprises the initialization of modules;
1.2 after receiving the voice RTP message that the SOCKETAPI side sends, this message logs in the FastCache module, at first can enter all RTP packet buffers that a cache memory section will receive to time buffering area.Then first message checking module can be with the message in the high-speed cache according to the fastest mode fast detecting, determine to remove non-RTP message, here the available index algorithm is realized packet check (such as realizing with increment hash algorithm) here, and uses hashtable as the problem that index will solve to be: how can be the bucket dynamic growth.The solution that has existed now is to expand hash, but also more complicated of this algorithm, and when different key had same hash value, the problem of infinite expanding can appear.Here I realize fairly simple and efficient at the increment hash algorithm that will introduce.Can be with reference to shown in Figure 3.
The principle of increment hash algorithm is comprised of multilayer bucket, shown in Fig. 3 top is divided.Can have n element among the bucket, each element, each element have the set form as shown in Fig. 3 the first hurdle.
What the flag field was preserved is the element what type this element belongs to, and shown in Fig. 3 bottom is divided, following 3 kinds of situations is arranged:
(1) equals 0 as flag, represent that this element is empty (for Fig. 3 hurdle third from the bottom).
(2) equal 1 as flag, represent that this element is a pointer (for Fig. 3 hurdle second from the bottom) that points to data record.
(3) equal-1 as flag, represent that this element is the pointer (for Fig. 3 hurdle last) of one deck under the sensing.
As can be seen from Figure 3, represent this element for empty when flag equals 0, then what does not all have to preserve.And representing that when flag is 1 this element is a pointer that points to data record, the offset field is the document misregistration amount of data file, and the key_length field is the length of key, data_length is the length of data.When flag equals-1, represent that this element is a pointer that points to next bucket, the step field is hash algorithm increment, and the bucket_size field is the size of next bucket, and the offset field is the document misregistration amount of next bucket.
1.3 when before after the RTP message that the logs in RTP message fast detecting in through 1.2, can again correct RTP be turned back in the hashtable high-speed cache and deposit, abandon non-RTP message, in this process, parallel is that message error detection occurs and voice remedy module also simultaneously with the message after the continuous verification of poll RTP correction verification module with it, followed by from hashtable, taking away, enter message and remedy module, this module detects the RTP message that needs mail to DSP again, and by after the traffic statistics, the RTP that loses can remedy transmission according to a kind of special equilibrium voice packet, and reaching the RTP that loses can timely effect of replenishing.
1.4 after remedying module and correction verification module and jointly finishing the error control of voice medium message, send to one by one DSP after being integrated into hashtable.
Voip phone of the present invention system is based on the realization after the embedded OS linux customization cutting, so the ICP/IP protocol stack that lowermost layer is the linux system to be provided, that mainly uses has IP, TCP, a UDP etc.At these more than basic agreement stack, use Session Initiation Protocol or H248 as signaling control protocol, and based on the RTP/RTCP agreement of UDP as the Real-Time Voice Transmission agreement, also realized simultaneously the application of some P2P, on agreement, done again some control hardwares, during session establishment, based on the RTP/RTCP message of UDP in the processing through herein FastCache module, made outstanding management in raising voice quality and secure data area, be worth using for reference.And this is applied to the simple in structure of VoIP system, and overhead is relatively little, and is powerful, and range of application is comparatively extensive.
The above-mentioned design of the present invention can be mainly used in the voice terminal system improving quality assurance and managing as efficient means, also can be placed on the local side apparatus and use.
