18. according to the device described in claim 11 to 14 any one, it is characterised in that described device also includes：
Processing module, if being not received by the BACH message for the base station, without special operational, continue just
Normal data dispatch.
19. according to the device described in claim 11 to 14 any one, it is characterised in that first sending module, specifically
For：
When the mobile terminal initiates activation request, according to predetermined sequence set and preset rules from the predetermined sequence set
The middle one of sequence of selection sends the BACH.
20. device according to claim 19, it is characterised in that second sending module, be specifically used for：
When only including a sequence in the predetermined sequence set, the testing result of the sequence is only represented whether to activate,
If the base station is activation to the testing result of the sequence, the base station sends predetermined system to the mobile terminal and disappeared
Breath；
When including multiple sequences in the predetermined sequence set, different sequences indicates different instruction types, the difference
Instruction type include different beam directions, different parameter sets numerology and/or different request contents, it is described
Base station determines the resource location and its content of the PBCH for different instruction types, and it is determined that PBCH resource locations send out
