ConfigIndex list)。
On broadcast SIB1 message and the opportunity of SIB2 message compared with as realizing and being in the embodiment of the present application, i.e., if any
Terminal needs network side equipment broadcast when random access to broadcast SIB1 message and SIB2 message.
The realization of SIB1 message is broadcasted compared with realization, when broadcasting SIB2 message, by SIB2 unlike existing realization
Prach-ConfigIndex parameter in message is revised as prach-ConfigIndex list.
Wherein, prach-ConfigIndex list includes N number of PRACH index；The value model of each PRACH index
Enclose is 0 to 63；The number for the numerical value for including in prach-ConfigIndex list is the same as the PLMN ID broadcasted in SIB1
Number is consistent, the corresponding PRACH index of each value.
N number of PRACH index is not all the same in the embodiment of the present application, or complete not identical.Which kind of specifically used mode realizes,
Determine according to actual needs.
Due to can repeatedly broadcast SIB2, when broadcasting SIB2 every time, it can choose not all the same or complete different
PRACH index carrying is broadcasted in prach-ConfigIndex list.
When realizing according to actual needs using complete different PRACH index, all random access letters may be implemented
The isolation in road.
When as sent SIB2 message every time, it can select in 64 PRACH index N number of, not have currently more optimizedly
There is the corresponding Physical Random Access Channel in random access channel position (the Physical Random Access of access user terminal
Channel, PRACH) the middle N number of PRACH index of selection of index (index).
When specific implementation, the corresponding PRACH index in random access channel position of accessed user's terminal can be directed to
It is marked；
N number of PRACH index is selected in not having markd PRACH index.
When the corresponding random access channel position any PRACH index is by there is user to be linked into no user access, delete
Except the label to the PRACH index.
