I want to know about the diff between soft and softer HO?3rd March 2006 at 08:56 #42115KumaGuest
Soft HO is between two cells at different sites. Softer HO is between two co-located (at same site) cells.3rd March 2006 at 09:03 #42116santyGuest
can u explain in terms of sector -carrier?3rd March 2006 at 09:36 #42117KumaGuest
Both Softer and Soft HO are within one frequency.3rd March 2006 at 09:39 #42118SantyGuest
What if one cell is 2 FA and other is 3 FA…And if the person on third frequency going to next site having two carriers?3rd March 2006 at 09:43 #42119nassimGuest
you have one parameter you need to adjsut in this case
RTD: round trip delay

Can u elaborate your point?3rd March 2006 at 10:04 #42121nassimGuest
When the mobile’s RTD passes upward through a datafilled threshold,the system steps in and orders a hard handoff to the matching sector of the bridge cell on the other system

hi santy, answer to ur question if person going from two carrier to third carrier site then there is no problem. He will get only hard handoff but if he is going from 3 carrier to 2 carrier site then u have to define parameter DAHO in 3c site so customer call will not get dropped when he is moving from 2c to 3c. I hope it will clear ur doubt.18th April 2006 at 07:18 #42124venkat eshGuest
This is in reference to A mobile moving from 3C to 2c.
let the frequencies with BTS A be F1,F2,F3 & BTS B be F1,F2.
If mobile is moving from A to B there is no problem, but if the mobile is moving from B to A and With The Mobile Hashed to F3. Then Border definitions have to be defined in such a way that F3 is H/O to F2.

Transalations allow selected sectors to be configured for Inter Frequency Handoff.To Maximize the coverage/Capacity acheived on aborder cell it is recommended that the only outward facing sectors of each Fn/Fi.Border cell be configured for Inter Frequency Handoff.The inward facing sectors will normally configured for Fn Traffic.
