Handover success rate issue


#1

We got multivendor in our network

HOSR from Ericsson to Nokia works well. But Nokia to Ericsson is very poor.

Any suggestions

#2

Handover through X2 or S1 ?


#3

Handover is through X2


#4

Does S1 is OK towards E//?


#5

Ericsson to Nokia both work well. But Nokia to Ericsson nothing…more are on X2…s1 attempts are very low


#6

Check x2 IP retrievals . check IP of enodeb in ipno and lnaj missmatch

Check the IP configs; I think IPconfig results in zero succes, is it the case ?

Did u check events’ thresholds ?


#7

Not all are failed
Some successes are also there


#8

Failures most come from intra or inter frequency


#9

Try to switch to s1 all att

Are HO thresholds on both vendors same or different?


#10

Handovers are Intra freq


#11

m8000c37 and c38 for IP x2 retr
