In this stage, mainly by suitable method, each user upgraded or information is transmitted is notified
Terminal.The content of required transmission includes：Specific upgrading mode, information of upgrade file check information, version number etc..If user
Terminal has default protocol with base station, this step can be omitted.One typical realization is as follows：Obtain the UE that multicast is needed to upgrade
Termination ID and IP；It is sent to UE terminals as upgrading information needed, including upgrade file title, version number, upgrade server IP
Location, upgrade file MD5 check informations etc.；Upgrade file is transmitted on multicast transmission server（MDS）；Determine what multicast needed
Resource, including radio resource situation, transmission mode etc..
Step 602：The data content of information need to be transmitted using the transmission of carousel form by concurrent channels.
The main purpose in this stage be let on remote upgrade user terminal obtain upgrade file wireless transmission method,
The action of single wireless sub- transmission block checking information and wireless network content prepares, and starts log-on data reception.This implementation

Extend 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 confirms in time after this document block is received
Whether it is properly received, considerably reduces the interaction time brought between user terminal and base station due to being verified.
In addition, base station will inform the user that blocks of files of the terminal to receiving in a manner of physics frame number in the embodiment of the present invention 1
It is counted, specific practice is：Inside of base station keeps the extension frame number of 18 bits, and the lower 16bit in this frame number is and empty
Frame number in mouthful is the same, kept after UE and base station synchronization, inside UE identical extension frame number and and inside of base station extension
Frame number synchronization.When UE notifies it that must at a time redirect by base station receives carousel signal, base station will send blocks of files 0（I.e.
Start file block）Extension frame number and current extensions frame number.UE receives the frame number actually sent, will be according to the frame number received
Real-time extension frame number is obtained, and derives blocks of files sequence number.This way largely avoided the wasting phenomenon of interface-free resources.

Independently judge that the receiving time of follow-up non-receiving portion it is expected, interacted if the reception expected time is much larger than with base station dedicated channel
Time, then terminal will be switched to dedicated channel, and base station is one-to-one interacts, and completes last data receiver, otherwise will
Continue to receive broadcast data in carousel channel.
Step 604：Data are received to user terminal and carry out data check and re-transmission.
After user terminal completely receives data, there are problems that a data check, the proposition of the embodiment of the present invention 1 is based on
The verification localization method of dichotomy, the data received to user terminal are verified and are retransmitted.Base station is according on user terminal
The check information of biography（The traditional algorithms such as CRC or MD5 may be used）, it is confirmed whether correctly, if incorrect, believes receiving
Number carry out two points according to length, submit the check information of respective block successively, base station to wherein verify incorrect part again into
Row segmentation, until navigating to erroneous block.It after Wrong localization block, is retransmitted, and according to the reverse order of positioning, successively from small
Arrival re-starts self checking, until whole error corrections.

Receive L blocks of files.It is indicated due to having carried out CRC check in multicast channel to each blocks of files with file block sequence, because
This user terminal clear and definite can received correctly M block, and remaining k=(L-M) a blocks of files is not properly received.
For the blocks of files that k file is not properly received, user terminal will be temporally optimal（Current total receiving time is most
It is short）Reception scheme received.The program realize principle be：Each data block block (i) not being properly received, i=0 ...
K-1 corresponds to N number of data source, it is contemplated that the Annual distribution of reception
When terminal is not properly received the ratio k/L of block less than some preset value, such as when 5% or all sequences that receives
Minimum expected reception value approachesWhen（It does not receive block at this time to be unevenly distributed, the stand-by period is long）, friendship will be transferred to
Mutual pattern.User terminal will carry out one-to-one interaction with base station, obtain remaining data block.
Step 703：Data check and re-transmission are carried out with base station.
In this step, user terminal uploads all check informations for receiving data first, in accordance with agreement（May be used CRC or
The traditional algorithms such as person MD5）, the block of all receptions according to dichotomy or Fibonacci method piecemeal is verified, searches erroneous block.
It after erroneous block is found, is interacted with base station and obtains correct block of information, information checking then is carried out to current block, if school
It tests and passes through, then to being verified comprising the block of information just by information checking；If not over dichotomy etc. is continued through
Method carries out location of mistake and is modified；If passed through, continue to expand the verification range of block of information（That is the mother of the block of information
Block）, and revised successively.Until all erroneous blocks correct.
