Specific embodiment
To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool
Body embodiment is described in detail.
The present invention in view of the prior art in there are part terminal can not upgrading support eMTC base station under normally access
The problem of, a kind of method for network access is provided, the base station of compatible enhanced machine type communication eMTC is supported applied to upgrading, such as
Shown in Fig. 1, comprising:
Step 11: obtaining master information block message；
Step 12: the master information block message is broadcasted；
Wherein, the number of repetition for being directed to system information block type 1 is not included in the master information block message and transmission block is big
Small index.
The method for network access provided in an embodiment of the present invention is by obtaining master information block message；By the Master Information Block
Message is broadcasted；Wherein, the number of repetition and transmission for system information block type 1 are not included in the master information block message
The index of block size；Enable to novel eMTC terminal by the normal access base station of blind examination, traditional LTE terminal also can be unaffected
Normal access base station (regardless of whether terminal or base station, which upgrade, is supported eMTC), ensure that existing net long-term evolving network LTE base station
Upgrading supports that having terminal after eMTC can access, and part terminal, which exists in the prior art, in very good solution to upgrade
Hold the problem of normally accessing under the base station of eMTC.
Specifically, the index is the scheduling information schedulingInfoSIB1-BR-r13 of system information block type 1.
The embodiment of the invention also provides a kind of method for network access, are applied to terminal, as shown in Figure 2, comprising:
Step 21: after the master information block message for receiving base station broadcast, blind examination obtains the repetition time of system information block type 1
Several and transport block size；
Step 22: according to the number of repetition and transport block size, accessing network.
After master information block message of the method for network access provided in an embodiment of the present invention by receiving base station broadcast,
Blind examination obtains the number of repetition and transport block size of system information block type 1；It is big according to the number of repetition and transmission block
It is small, access network；Enable to novel eMTC terminal by the normal access base station of blind examination, traditional LTE terminal also can be unaffected
Normal access base station (regardless of whether terminal or base station, which upgrade, is supported eMTC), ensure that existing net long-term evolving network LTE base station
Upgrading supports that having terminal after eMTC can access, and part terminal, which exists in the prior art, in very good solution to upgrade
Hold the problem of normally accessing under the base station of eMTC.
Wherein, it is used to indicate the number of repetition dial gauge of the number of repetition of system information block type 1；And it is used to indicate and is
The transport block size dial gauge of the transport block size for type of information block 1 of uniting is that base station and terminal shift to an earlier date protocol conventions；This reality
It applies in example, terminal blind examination is also this two tables, that is, this two tables obtain the repetition of system information block type 1 by blind examination
Number and transport block size.
Specifically, blind examination obtains the weight of system information block type 1 after the master information block message for receiving base station broadcast
Again the step of several and transport block size includes: and passes sequentially through 4 repetitions to attempt decoding for different transport block sizes；If
Successfully decoded makees transport block size at this time then using number of repetition at this time as the number of repetition of system information block type 1
For the transport block size of system information block type 1.
Further, the method for network access further include: if decoding failure, different biographies is directed to by 8 repetitions
Defeated block size attempts decoding；If successfully decoded, number of repetition of the number of repetition as system information block type 1 at this time will
Transport block size of the transport block size at this time as system information block type 1；If decoding failure, is directed to by 16 repetitions
Different transport block sizes attempts decoding；If successfully decoded, repetition of the number of repetition as system information block type 1 at this time
Number, using transport block size at this time as the transport block size of system information block type 1.
Illustrate herein, the scheme of the embodiment of the present invention is to attempt solution for different transport block sizes by different repetitions
Code still fails until successfully decoded or all numbers of repetition have been attempted, just terminates process；But not as
Limit.
Below with reference to base station and terminal two sides, the method for network access provided in an embodiment of the present invention is carried out further
Explanation.
In order to guarantee that existing net LTE base station upgrading supports that having terminal after eMTC can access, the embodiment of the present invention provides one
Kind method for network access: has terminal not by shadow after guaranteeing existing net LTE base station upgrading eMTC ability by using the mode of blind examination
It rings.SchedulingInfoSIB1-BR-r13 will not be carried inside base station broadcast MIB message.
Wherein, according to schedulingInfoSIB1-BR-r13, which is directed toward two tables.
First table (such as Table 7.1.6-1) is to be used to indicate SystemInformationBlockType1-BR (to be
Unite type of information block 1) number of repetition.
Second table (Table 7.1.7.2.7-1) is to be used to indicate SystemInformationBlockType1-BR
The TBS (transport block size) of (system information block type 1).
SystemInformationBlockType1-BR (system information block class could be normally parsed by this two tables
Type 1) information.
By this two tables of blind examination normally to parse in the embodiment of the present invention
SystemInformationBlockType1-BR (system information block type 1) information.
Table 7.1.6-1:Number of repetitions for PDSCH
CarryingSystemInformationBlockType1-BR for BL/CE UE. is (for BL/CE terminal, in PDSCH
Carry the number of repetition of SystemInformationBlockType1-BR (system information block type 1))
