I want to know about two feature in Ericsson 3G:
IRC&HOPB/EHOSR and DYMA. All I know is that they are related to 3G on 900MHz and they are use to provide better qulity and to improve 2G Call Drop Rate.
Can somebody help me. If there is some kind of documentation or links in internet I will be very grateful.
Thanks a lot.
Hi Toma IRC sounds like interference reject combining. But this is a feature for improvemento the uplink interference and therefore improvement of drop call. We have this feature in our GSM network. Never eard of it for UMTS (i’ll check if exist in 3g and I’ll let you know). Dyma is also a gsm feature
