Stochastic accessing is that UE is starting and the access procedure before network service.Physical layer RACH (PRACH)
For transmitting random access resource, i.e. random access guiding (Random Access Preamble).
LTE random access procedures can be divided into (risk for having collision) based on competition and based on two non-competing classes.
In random access procedure based on competition, UE can randomly select a random access guiding and be transmitted, it is clear that this there is more
Individual UE sends the possibility of same preamble, and eNB can take Conflict solving process to handle the problem.Connect at random based on non-competing
During entering, eNB can be by distributing Special leader to UE so as to the generation of collision free, it is clear that such a mode is than based on competing
The mode striven is efficient, and this is a very important factor for the switching limited with strict time.
For each cell, 64 fixed random access guidings be present.For existing two kinds of Stochastic accessing sides
Formula, this 64 targeting sequencings can be divided into two parts, a part is used for the Stochastic accessing based on competition, and another part is used for base
In non-competing Stochastic accessing.Serving cell can tell UE to be used for the random access guiding based on competition by system information broadcast
Number (numberOfRA-Preambles in SIB2), i.e. in 64 preamble preceding numberOfRA-Prambles with
Machine access lead is used for the Stochastic accessing based on competition.
Random access guiding based on competition is divided into two groups (Group A and Group B) to by the way which group selected again
It is leading implicitly to carry 1bit information, that is, send the letter of the transfer resource total amount needed for the 3rd step message (Message3)
Breath.UE can judge that this chooses targeting sequencing in being grouped from which according to the 3rd step potential size of message pending, and system can
Message3 possibility size is judged with the packet according to where the preamble that UE is sent, so as to avoid distributing excessively
Ascending resource causes the wasting of resources to UE.Serving cell can inform the configuration of UE preamble packets by system information broadcast

The Message3 length sent is less than the threshold value, just selects GroupA, otherwise, selects GroupB.
MessagePowerOffsetGroupB (in SIB2) represents that (message compares selection GroupB transmissions Message3
Power greatly) relative to the power for sending conventional size Message3 offset.
MaxHARQ-Msg3Tx (in SIB2) represents to retransmit Message3 maximum times.
Because the random access procedure of common LTE terminal and the random access procedure of colony terminal are concurrently to deposit in public network
, to distinguish the Stochastic accessing of the Stochastic accessing of LTE terminal and colony terminal, it is necessary to which colony terminal Stochastic accessing mistake will be used for
The resource of journey distinguishes with the resource for common LTE terminal random access procedure.Access for common LTE and connect for cluster
