Technical field
The present invention relates to the wide band CDMA radio network, refer to a kind of method that user face data in the network is followed the tracks of especially.
Background technology
Fig. 1 is the Radio interface protocols configuration diagram.System is divided into chain of command signaling and user plane information as we can see from the figure, and the chain of command signaling is sent out the RLC (Radio Link control) that low layer is given in control information, MAC protocol layers such as (media interviews controls) by RRC; And user plane information by each protocol layer of L2, sends to the transmission channel of L1 by radio bearer.
The information of user's face mainly is data message for the chain of command signaling, browses as online, and the content of webpage is exactly the information of user's face, and it is that information transfer channel by user's face sends to the user's.At the L2 of user's face protocol layer, these messages all are the forms of packet one by one, and concrete content L2 has no way of learning.And when user plane information in L2 protocol layer internal transmission the time, be not the IU mouth of agreement regulation, the standard message of UU mouth (although its frame structure agreement regulation is very clear, the content of data is had no way of as can be known).From the angle of user's face, all message all is packet, and its particular content is unknowable for user's face, and the size of message of user's face is very huge, uses the method for tracking Control plane signaling, and it is impracticable following the tracks of user plane information.
Yet user plane information is again very important for whole system, if user's face goes wrong, unavailable as the data link, rlc protocol layer problem such as reset, then user's conversation or communication will be interrupted, and directly influence the performance of RNC (radio network controller) system.And the problem place can't be known fast by system when user's face goes wrong, is difficult to the location, is beyond affordability for the user, thus need follow the tracks of the information of user's face, to make things convenient for orientation problem.
A kind of method that user plane information is followed the tracks of in the prior art is to follow the tracks of each user side data bag at standard interfaces such as IU interface and UU interfaces, uses each layer of L2 corresponding protocols that each packet is parsed then, analyzes.
The shortcoming of prior art:
1. the quantity of data packets of resolving at interface is too big, and a lot of packets are worth not high for problem analysis.
2. under multi-user's situation, the information of difficult tracking unique user.
3. data volume is huge, can't show in real time on user terminal, and the communication of Device Host end and background user terminal is difficulty relatively.

Embodiment
The present invention is distributed in different layers with each performance index that require to add up and adds up according to each protocol layer of L2, and each layer is according to the index of distributing, when sending or receiving data, add up, statistics sends to the rear end administration module in the mode of information reporting.Statistics mainly is at RLC (RadioLink Control, Radio Link control) protocol layer, MAC (Media Access Control, media interviews control) protocol layer and FP (Frame Protocol, Frame Protocol) protocol layer carries out, because these three layers is relevant data transmission most important part in the L2 agreement.The user plane data tracking of L2 can be configured on the user terminal of rear end administration module, can be to known IMSI (International Mobile SubscriberIdentify, the inner sign of mobile subscriber) single UE (subscriber equipment) follows the tracks of, can be unit with the sub-district also, follow the tracks of the calling or the transfer of data of carrying out.The user can be configured statistical message pattern that reports and the cycle that reports.
Specific implementation process is as follows:
The user imports IMSI that follows the tracks of UE or the sign of importing the sub-district on the operation interface of rear end administration module, select to follow the tracks of the performance index of statistics; Can include: the statistics of the TB of dedicated transmission channel (TransportBlock, transmission block) performance, the statistics of RLC retransmission rate, the performance statistics of RLC buffer memory occupancy, the statistics of the TB performance of common signal channel, the statistics of frame (TB) error rate, the statistics of reverse power control etc.;
(Back Administration Modu1e BAM) will follow the tracks of configuration messages and be handed down to entity in the protocol layer rear end administration module, and each entity is configured according to the result that is provided with to the performance index of following the tracks of in the configuration messages;
When each entity carries out the datagram transmission of messages, the performance index of statistics are carried out statistical work;
Each entity in real time sends to rear end administration module to the information of statistics in the mode of message according to certain rule that reports;
The rear end administration module is resolved each statistical message bag after receiving the statistical message of entity transmission, and the order of receiving according to message shows on the user terminal interface of rear end administration module then.Every message is as a display items, after the double-click message, with the full content of display message.
In the said method in the statistics of rlc protocol layer: because RLC is the control section that the L2 number passes user's face, some index parameters of RLC have determined the effect of transfer of data.When RLC carries out downlink data transmission, at each Transmission Time Interval, under ratio that the packet that the buffer memory occupancy of RLC, RLC are retransmitted is shared and the non-transparent mode in the transmit queue the shared parameters such as ratio of packet add up respectively, when report cycle, be carved into, these statistical informations are reported the rear end administration module with the mode of message.Simultaneously, empty the value of the statistics that has reported, begin the statistics of a new measurement period.
Statistics in the MAC protocol layer is: the major function of MAC protocol layer is to realize the mapping of logic channel to transmission channel, so will receive and the number of the packet that sends is added up each TTI at the MAC protocol layer, regulation according to agreement, MAC will be to CRCI (Cyclic Redundancy CheckIndication, the cyclic redundancy check (CRC) indication) indication is checked, and the number of CRCI error data packets is added up.The MAC protocol layer is when receiving each packet, can be to this packet CRCI mistake whether, comprise several data transmission blocks, the distribution of CRCI erroneous packets, statistical parameters such as the size of data transmission block are added up, and are recorded in the corresponding variable, when arriving Deng report cycle, with the content of these variablees, send to the rear end administration module with the form of message, carry out respective handling and video data by BAM.MAC also has an important statistical function, be exactly to work as UE in the switching state of D2F (the DCH state is to the FACH state) or F2D (the FACH state is to the DCH state), MAC-d (Media Access Control (Dedicate) to the UE correspondence, media interviews controls (private part)) data that send at MAC-c/sh (media interviews control-public/shared portion) are also added up, thereby can monitor the handoff procedure of whole channel.
Statistics at the FP protocol layer: a major function of FP protocol layer is to many RL (Radio Link, Radio Link) manages, the statistics of carrying out at the FP protocol layer mainly is the situation of each RL, comprise every RL in the process of once up merging, TB Number of the data of receiving (transmission block number) and TB Size (transmission block size); The CRCI situation of the packet of each branch road and QE (QualityEstimate, quality is estimated) situation; Merge each RL takies in the up packet in back ratio etc.These statistical informations can be periodic reports, also can be Event triggered, behind each reporting message, just restart statistics.For example, value for the power control relevant with the RL link-quality, can be set to Event triggered reports, as long as SIR (the Signal to Interference Ratio of UE correspondence, signal to noise ratio) desired value changes, just some statistical values are reported, therefrom can analyze is that what propagation channel quality sir target good or that badly cause is worth to change.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claims.
