Scape, and select the terminal UE being redirected to adjacent homologous ray alien frequencies or different system cell；If above-mentioned uplink transmission power does not surpass
Threshold value is crossed, then can tentatively judge that the terminal UE is in center of housing estate or low interference scene, it can according to actual needs, by the terminal UE
Be redirected to covering Chong Die with this cell or this frequency point homologous ray alien frequencies or different system cell；Base station can not also select detection eventually
UE uplink transmission power is held, is directly the specified goal systems redirected of terminal UE or frequency point or cell.
In a preferred embodiment, terminal UE need to re-initiate initially after receiving redirection order in Target cell
Change business can not be disconnected actively.
Redirect process can not only occur in the random access procedure, can also occur at random access procedure it
Afterwards.As shown in figure 9, in a preferred embodiment, when terminal UE initializes a business, detecting that terminal executes random
Access procedure, triggering redirect process and include:
Random access is being completed, and after establishing corresponding carrying, base station carries out deep packet to carrying data packet
Detection；
If detecting first kind message in carrying data packet, current preset condition is detected in base station, if preset condition
It has been more than threshold value, then has triggered redirection process.First kind message specifically can be invitation (INVITE) message of calling terminal.
In an application scenarios, for VoLTE business-i.e. voice call service type, random access, QCI9 with
QCI5 establish complete after, base station to QCI5 data packet carry out deep-packet detection, the data packet may for invite (INVITE),
PRACK, UPDATE etc.；
If it is detected that INVITE message, current preset condition is detected in base station, such as wireless environment quality, disturbed condition, bears
Lotus situation and quality of service etc. trigger redirection process if preset condition is more than threshold value；
Current preset condition is detected in above-mentioned base station, can be to detect itself preset condition, can also be by adjacent with other
