For network equipment, avoid or end have a variety of for the mode of the handover operation of described subscriber equipment:
If the described network equipment of mode one is received described notification message before the switching of described subscriber equipment is adjudicated, stop adjudicating, avoid the handover operation for described subscriber equipment.
If the described network equipment of mode two is adjudicated described subscriber equipment, need to switch, and received described notification message before sending switching command, stop sending described switching command to described subscriber equipment, avoid the handover operation for described subscriber equipment.
If the described network equipment of mode three is received described notification message after described subscriber equipment sends described switching command, stop follow-up handover operation, end the handover operation for described subscriber equipment.
If the described network equipment of mode four is received described notification message after described subscriber equipment sends described switching command, to described subscriber equipment, send handover cancelling order, and stop follow-up handover operation, end the handover operation for described subscriber equipment.
For mode three, if described subscriber equipment is received the switching command from described network equipment, ignore described switching command, and be switched in non-cellular network.
For mode four, if described subscriber equipment is received the switching command from described network equipment,, after the handover cancelling order of receiving from described network equipment, be switched in non-cellular network.
For mode four, in force, subscriber equipment also can be set a timer, after sending a notification message to network equipment, start timing, if do not receive the handover cancelling order from described network equipment in setting duration, have two kinds of processing modes: 1, be switched in non-cellular network; 2, carry out normal switching flow with network equipment.Which kind of can be set as required in concrete employing.

Enumerate the example of the scheme of two embodiment of the present invention below.
Example one, as shown in Figure 8, the embodiment of the present invention eight is carried out in the application scenarios schematic diagram of switch decision, and UMTS extensively covers, and in order to improve the throughput of system, operator has disposed LTE Hot Spot and WIFI focus in bustlinier commerce area again.UE starts to be connected under LTE CELL1, and along with the movement of UE, UE shifts out the coverage of LTE cell1, enters into the overlay area of WIFI focus.This UE is the UE that low speed moves, and core net is LTE<WLAN to the ANDSF strategy of UE configuration, UMTS<WLAN.
For the scene of Fig. 8, the embodiment of the present invention has provided a kind of method of carrying out switch decision, as shown in Figure 9:
Step 901, UE are connected under LTE community, consider and also have WIFI focus around, and the Serving cell of UE can send to UE by system message or dedicated signaling by the handoff threshold between 3GPP RAT and WLAN
Step 902, UE send that periodic measurement reports or the measurement of Event triggered reports.
Step 903, along with the movement of UE, the edge of UE Dao Liao LTE community.The Serving cell of UE reports according to the measurement of UE, and judgement UE need to move to UMTS cell2.Meanwhile, because Serving cell UE should be switched to WLAN focus according to the handoff threshold judgement of the ANDSF strategy of self and Serving cell configuration.
Step 904, UE send the notification message that is switched to non-cellular network to network side.
Step 905, UE are connected to behind UMTS community, proceed the measurement of 3GPP RAT and WLAN, and according to measurement result and ANDSF strategy, UE is switched to wlan focus.
Step 906, WLAN provide service for UE.
Example two, as shown in figure 10, the embodiment of the present invention ten is carried out in the application scenarios schematic diagram of switch decision, LTE cell2 extensively covers, and in order to improve the throughput of system, in bustlinier commerce area operator, has disposed again LTE Hot Spot cell1 and WIFI focus.UE starts to be connected under LTE CELL1, and along with the movement of UE, UE shifts out the coverage of LTE cell1, enters into the overlay area of WIFI focus.Core net is LTE<WLAN to the ANDSF strategy of UE configuration.
Under this scene and the scene comparing class of Fig. 8 seemingly.Different places are, are the regions extensively covering at LTE, have disposed LTE Hot Spot cell1 and WLAN focus.Movement along with UE, the signal quality of LTE Hot Spot is variation gradually, according to intra-lte switchover policy, LTE cell1 may be switched to UE LTE cell2, and UE may think according to oneself switch decision and need to be switched to WLAN, within the short time, there is this unnecessary continuous switching of LTE CELL1-> LTE CELL2->WLAN, UE detects behind suitable WLAN community, send the indication that suitable wlan community oneself detected to the LTE cell1 of service, like this, network side is according to the state of network, the switching that the Determines of UE can not initiated LTE inside to UE is to avoid unnecessary handoff procedure.
