Re: Missed call when mobile attached on 3G
Hello:
Did you solved your issue ? , we faced a similar problem here with similar CS Paging Success Rates in fact I noticed from your post that 91% is actualy a low value we had missing calls issue under 96% .
We did a long investigation and we found out that the PS Paging was so huge that was filling up the paging channels in radio so there was no room for CS Paging ( may be that´s why you see paging coming out but there is no answer in our case that paging message was not reaching the user at all)
The main reason behind this was the use of Smartphones with Fast Dormancy Features that takes them into idle very quickly creating this huge PS Paging situation. Bottom line we took all the Iphones into private ip addresses ( and NAT of course) , this reduced the PS Paging and increased the CS Paging Success Rate and now there are no more missing calls
hope this helps
