LTE HANDOVER EVENTS

[b]The LTE Event A1[/b] is triggered when the serving cell becomes better than a threshold. The event is triggered when the following condition is true:                       
                       
MEAsserv - Hyst > Threshold                       
                       
Triggering of the event is subsequently cancelled when the following condition is true:                        
                       
MEAsserv + Hyst < Threshold                       
                       
The hysteresis can be configured with a value between 0 and 30 dB.                       

[b]The LTE Event A2[/b] is triggered when the serving cell becomes worse than a threshold. The event is triggered when the following condition is true:                            
                           
MEAsserv + Hyst < Threshold                            
                           
Triggering of the event is subsequently cancelled when the following condition is true.                            
                           
MEAsserv - Hyst > Threshold                            
                           
The hysteresis can be configured with a value between 0 and 30 dB.                           

[b]The LTE Event A3[/b] is triggered when a neighbouring cell becomes better than the serving cell by an offset. The offset can be either positive or negative. The event is triggered when the following condition is true:                           
                           
MEASneigh + Oneigh,freq + Oneigh,cell - Hyst > MEASserv + Oserv,freq + Oserv,cell + Offset                            
                           
MEASneigh + Oneigh,freq + Oneigh,cell + Hyst < MEASserv + Oserv,freq + Oserv,cell + Offset                           

[b]The LTE Event A4[/b] is triggered when a neighbouring cell becomes better than a threshold.                            
                           
MEASneigh + Oneigh,freq + Oneigh,cell - Hyst > Threshold                            
                           
Triggering of the event is subsequently cancelled when the following condition is true:                           
                           
MEASneigh + Oneigh,freq + Oneigh,cell + Hyst [b]
LTE Event A5[/b] is triggered when the serving cell becomes worse than threshold-1 while a neighbouring cell becomes better than threshold-2. The event is triggered when both of the following consitions are true:   
   
MEASserv + Hyst < Threshold-1    
   
MEASneigh + Oneigh,freq + Oneigh,cell - Hyst >Threshold-2   
   
Triggering of the event is subsequently cancelled when either of the following conditions are true:   
   
MEASserv - Hyst > Threshold-1    
   
MEASneigh + Oneigh,freq + Oneigh,cell + Hyst
[b]The LTE Event B1[/b] is triggered when a neighbouring inter-system cell becomes better than a threshold. The event is triggered when the following condition is true:    
   
MEASneigh + Oneigh,freq - Hyst > Threshold    
   
Triggering of the event is subsequently cancelled when the following condition is true:   
   
MEASneigh + Oneigh,freq + Hyst < Threshold   

[b]The LTE Event B2[/b] is triggered when the serving cell becomes worse than threshold-1 while a neighbouring inter-system cell becomes better than threshold-2. The event is triggered when both of the following conditions are true:               
               
MEASserv + Hyst < Threshold-1                
               
MEASneigh + Oneigh,freq - Hyst > Threshold-2                
               
Triggering of the event is subsequently cancelled when either of the following conditions are true:                
               
MEASserv - Hyst > Threshold-1                
               
MEASneigh + Oneigh,freq + Hyst < Threshold-2
