Description
Technical field
The utility model relates to digital communicating field, is specifically related to a kind of testing equipment of communication signal.
Background technology
Air-interface information abbreviates idle message or space interface signaling as, is the communications protocol of base station and terminal.Idle message is one of important means of location wireless telecommunication system network failure, by the analysis to idle message, can locate the reason that critical events such as call failure, call drop, handoff failure take place.Processing support to idle message is provided, and is the basic function of wireless network test analysis meter, signaling tracing instrument.
Idle message generally manifests in various instrument with the form of tabulation, and the content that comprises in the tabulation is: message time stamp T ime Stamp, channel name, message name.By clicking a certain idle message in the tabulation, the detailed content that can check the idle message of being clicked.This processing mode has only comprised the substance of idle message, in actual use, has following deficiency:
1) can't intuitively show idle message frequency points corresponding number.In overloading overlay area frequently, terminal can be switched between different carrier frequency, and changing the frequency switching is direct-cut operation, easily causes variety of issue.In order to carry out the location of relevant issues, the engineer often need check the carrier frequency number at idle message place.Conventional idle message processing mode, this information can't directly be provided, the engineer often need contrast the frequency point information that other state interface (as the terminal's status information display interface) is provided repeatedly, can roughly recognize the pairing frequency point number of certain bar idle message.The quantity of idle message is a lot, and frequency point information changes through regular meeting, and the efficient of artificial contrast is very low, and very easily makes mistakes.
The user identification number International Mobile Subscriber Identity of the idle message that 2) can't intuitively show on the common signal channel to be sent is called for short IMSI number.Idle message on the common signal channel is to send and receive with the form of broadcasting, and has the idle message on the part common signal channel to attach IMSI number, need be by specific terminal reception or from specific terminal in order to identify this message.When carrying out signalling analysis, often need know that the idle message on certain bar common signal channel belongs to that station terminal transmission or reception.As checking on the CDMA paging channel, the base station is those terminals of paging in a certain period, under the conventional idle message display mode of general instrument, the engineer needs to click successively all the General Page message in the tabulation, and in the content of General Page message, check IMSI number, and the content of message is used tree-like demonstration often, and the engineer needs repeatedly the node of tree layout can see IMSI number.As seen, conventional idle message display mode checks that IMSI number operating procedure is many, and efficient is low.
Summary of the invention
Technical problem to be solved by this invention just provides code multiplexing and the decoding Deplexing method in a kind of Traffic Channel, retransmission technique obtains enough link gains by adopting fast, the data set phase method also can make organizing of data more flexible simultaneously, to avoid influencing because of curing data length the efficiency of transmission of mobile communication.

(1) business datum of input is carried out error correction coding;
(2) business datum after the error correction coding is stored forwarding, and whether retransmit according to the feedback information decision of receiving terminal;
(3) according to physical frame data carried by data amount the data of storing after transmitting are carried out rate-matched;
(4) carry out fixed segments through the data after the rate-matched;
(5) data of gained after the fixed segments are carried out interleaving treatment;
(6) data map after will interweaving is in the physical channel frame.
Wherein, the described error correction coding of step (1) comprises the steps:
(1-1) to business datum additional cycles redundancy check bit;
(1-2) data after the additional check digit are carried out segmentation;
(1-3) data after the segmentation are encoded.
Wherein, the described repeating transmission of step (2) comprises, needs the instruction of retransmitting when receiving terminal returns, and then transmitting terminal continues to retransmit, and then stops to retransmit when transmitting terminal acknowledges receipt of the instruction that need not to retransmit.Wherein, further comprise, retransmit the mode that adopts part to retransmit or all retransmit and carry out the repeating transmission of data.
Wherein, described step (3) further comprises, goes up and does the punching compression in limited time and handle when data volume surpasses the physical frame carrying, carries out repeated and redundant when data volume in limited time on less than the physical frame carrying and handles.
Wherein, the decoding Deplexing method in a kind of Traffic Channel comprises the steps:
(A) physical channel data is extracted from physical channel;
(B) the described data that extract are carried out deinterleaving and handle, obtain each segment data;
(C) each segment data is made up;
(D) data that obtain after the combination are carried out error-correcting decoding;
(E) whether obtain correct raw information according to error correcting deocder and judge whether needs send the repeating transmission instruction.
Wherein, the described error-correcting decoding of step (D) comprises the steps:
(D1) redundant data that produces of deletion transmitting terminal or the cavity position of transmitting terminal carried out zero padding;
(D2) data result of repeatedly retransmitting that obtains after the above-mentioned processing is carried out soft merging;
(D3) data after being combined are deciphered.
Wherein, described step (D2) further comprises, the data that whole repeating transmission or part are retransmitted merge.
Wherein, described step (E) further comprises, sends the re-send request may instruction when decoding error, sends the instruction that acknowledges receipt of and need not to retransmit when decoding is correct.
Method of the present invention by Error-correcting Encoding and Decoding, data re-transmission and punching or repeat techniques, has promoted the Block Error Rate performance of block domain data, thereby has improved the throughput of link.
