Below in conjunction with the accompanying drawing in embodiments of the invention, the technical scheme in embodiments of the invention is carried out clear
Chu, it is fully described by, it is clear that the embodiments described below are only a part of embodiment of the invention, rather than whole realities
Apply example.Based on the embodiment in the present invention, those of ordinary skill in the art are obtained under the premise of creative work is not made
Every other embodiment, belong to embodiments of the invention protection scope.
As shown in figure 1, be a kind of schematic flow sheet of network shunt method provided in an embodiment of the present invention, can include with
Lower step：
Step 101, eNB are monitored to LTE network flow.
Step 102, eNB send the message that WLAN connections are carried out for triggering UE to UE.Wherein, carried in the message
The LTE network traffic conditions that eNB is monitored.
Specifically, in embodiments of the present invention, eNB can in real time be monitored to LTE network flow, and according to monitoring
LTE network traffic conditions to UE send triggering UE carry out WLAN connections message.For example, the LTE network stream monitored as eNB
When amount situation reaches predetermined threshold value, eNB can send the message that WLAN connections are carried out for triggering UE to UE.
Wherein, when eNB is monitored to LTE network flow, the LTE network flow monitored can be the reality of LTE network
The ratio of the total flow loaded of border load flow and LTE network, LTE network flow grade, and root are determined according to the ratio
According to the LTE network flow grade message that triggering UE carries out WLAN connections is sent to UE.
Wherein it is possible to flow grade division be carried out to LTE network in eNB sides in advance, for example, when LTE network actual loading
The ratio no more than first threshold for the total flow that flow can be loaded with LTE network（Such as 30%）When, determine LTE network flow grade
For the first order（30% is first order upper limit threshold）；The total flow that can be loaded when LTE network actual loading flow and LTE network
Ratio is more than first threshold, but no more than Second Threshold（Such as 50%）When, it is the second level to determine LTE network flow grade（50% is
Second level upper limit threshold）；When the ratio for the total flow that LTE network actual loading flow and LTE network can be loaded is more than the second threshold
Value, but no more than the 3rd threshold value（Such as 80%）When, it is the third level to determine LTE network flow grade（80% is third level upper limit threshold
Value）.ENB can in real time be monitored to LTE network flow, and reach the first/bis-/tri- threshold values when monitoring LTE network flow,
