Embodiment 1:
The embodiment of the present invention 1 provides the base station in LTE1800 group system user terminal to be carried out to the information transmitting methods of ftp upgrading, describes the specific implementation process of the embodiment of the present invention in detail, see Fig. 6:
The transmission preparation of step 601:ftp upgrading.
In this stage, mainly by suitable method, notify that each needs to carry out upgrading or the user terminal of information transmission.The content of required transmission comprises: concrete upgrading mode, information of upgrade file check information, version number etc.If user terminal and base station have default protocol, this step can be omitted.One typically realizes as follows: obtain the UE Termination ID and IP that need multicast to upgrade; Be sent as upgrading information needed to UE terminal, comprise upgrade file title, version number, upgrade server IP address, upgrade file MD5 check information etc.; Upgrade file is delivered to (MDS) on multicast transmission server; Determine the resource that multicast needs to comprise Radio Resource situation, transmission mode etc.
Step 602: adopt carousel form to send the data content needing transmission of information by concurrent channels.
The main purpose in this stage is that the let on user terminal of remote upgrade obtains the wireless transmission method of upgrade file, single wireless sub-transmission block check information, and the action of wireless network content prepares, and starts log-on data and receive.In the present embodiment 1, circulate successively and send total data content in base station between each concurrent channels, and sent data content is divided blocks of files and sends self checking information, send the required out of Memory of upgrading: as the expansion frame number of start file block simultaneously, current extensions frame number, general act block number, multicast subband number, multicast CQI etc.
Wherein, the self checking added for each blocks of files can ensure that user terminal is confirmed whether correct reception in time after this blocks of files of reception, considerably reduces the interaction time brought owing to carrying out verifying between user terminal and base station.
In addition, in the embodiment of the present invention 1, informing user terminal is added up the blocks of files received in the mode of physics frame number by base station, specific practice is: inside of base station keeps the expansion frame number of 18 bits, lower 16bit in this frame number be with eat dishes without rice or wine in frame number be the same, after UE and base station synchronization, UE inside keeps identical expansion frame number and and the expansion frame number synchronization of inside of base station.When UE by base station notify its must at a time redirect receive carousel signal time, base station will send blocks of files 0(and start file block) expansion frame number and current extensions frame number.UE receives the frame number of actual transmission, obtains real-time extension frame number by according to the frame number received, and derives blocks of files sequence number.This way largely avoided the wasting phenomenon of interface-free resources.
Step 603: when sent data content arrives setting threshold, user terminal expects the follow-up send mode judged according to the time of reception of non-receiving unit, the information that completes sends.
In this step, when user terminal completes 95%(or a certain set point at carousel channel) after above data receiver, to independently judge that the time of reception of follow-up non-receiving unit is expected, if receive the expected time much larger than the time mutual with base station dedicated channel, then terminal will be switched to dedicated channel, carry out one to one alternately, completing last data receiver with base station, otherwise will continue to receive broadcast data at carousel channel.
Step 604: data are received to user terminal and carries out check sum re-transmission.
After the complete reception data of user terminal, there is the problem of a data check, the embodiment of the present invention 1 proposes the verification localization method based on dichotomy, verifies the data that user terminal receives and retransmits.Base station is according to the check information (can adopt the traditional algorithms such as CRC or MD5) of user terminal uploads, be confirmed whether correct, if incorrect, then Received signal strength is carried out two points according to length, submit the check information of respective block successively, base station is split, until navigate to erroneous block again to wherein verifying incorrect part.When after Wrong localization block, retransmit, and according to the reverse order of locating, re-start self checking from little arrival successively, until whole error correction.
Embodiment 2:

Step 701: the data content of transmission of information that needs that base station adopts carousel form to send by concurrent channels is received.
In this step, user terminal not only receives the ftp information of upgrade file of base station carousel, also can receive the expansion frame number of the start file block that base station sent, current extensions frame number information, obtain real-time extension frame number with this, and derive the sequence number of blocks of files.
In addition, the blocks of files self checking information that user terminal also can send by receiving base station is confirmed whether to proper reception of blocks of files in time, considerably reduces the interaction time brought owing to carrying out verifying between user terminal and base station like this.
Step 702: when received data content arrives setting threshold, by expecting that the follow-up send mode judged completes receives information to the time of reception of non-receiving unit.
In this step, when terminal is after carousel channel completes the above data receiver of setting threshold, to independently judge that the time of reception of follow-up non-receiving unit is expected, if receive the expected time much larger than the time mutual with base station dedicated channel, then be switched to dedicated channel, carry out one to one alternately, completing last data receiver with base station, otherwise continue to receive broadcast data at carousel channel.The reception programme that user terminal is detailed is as follows:
Stochastic choice multicast channel, complete sequence receives the data in a Period cycle.L blocks of files will be received completely in this cycle.Owing to all having carried out CRC check to each blocks of files in multicast channel and file block sequence indicates, therefore user terminal clearly can proper reception of M block, and remaining k=(L-M) individual blocks of files does not correctly receive.
For the blocks of files that k file does not correctly receive, the reception programme of temporally optimum (current total time of reception is the shortest) receives by user terminal.The principle that the program realizes is: each incorrect the data block block (i) received, i=0 ... k-1, equal corresponding N number of data source, the Annual distribution that expection receives
Wherein t
0for block (i) is in N number of multicast channel nearest time of reception.All incorrect data block reception scheduled times received are sorted, makes receive channel strategy and reception order.Owing to there is the situation that the nearest time of reception of data block overlaps, minimum channel switching times now can be adopted as the supplementary principle of sequence.Owing to adopting the principle of out of order reception, when as N less (during N<6), k is greater than 10% of overall File block length L, equivalent received speed is
When terminal does not correctly receive the ratio k/L of block lower than certain preset value, such as 5% time, or all receiving sequences minimum expected reception value close
time (now not receiving block skewness, waits for too long), will interactive mode be proceeded to.User terminal will carry out mutual one to one with base station, obtain remaining data block.
Step 703: carry out check sum re-transmission with base station.
In this step, first user terminal uploads the check information (can adopt the traditional algorithms such as CRC or MD5) of all reception data according to agreement, verify, search erroneous block to the block of all receptions according to dichotomy or Fibonacci method piecemeal.When after discovery erroneous block, carrying out obtaining correct block of information alternately with base station, then information checking is carried out to current block, if verification is passed through, then just being verified by the block of information of information checking comprising; If do not passed through, then continue through the methods such as dichotomy and carry out location of mistake and revise; If passed through, then continue the verification scope (i.e. the mother tuber of this block of information) expanding block of information, and revise successively.Until all erroneous blocks correct.
After user terminal receives all upgrade files, original version file is retained to original document district, and starts local file renewal.When transaction file correctly by after standard testing, can will be marked as available edition, when can not correctly pass through, will recover prototype version.
