multi carrier

[elmorabet]

we are going to implement the 3G sites with three carriers so I am asking what's the recommended stratigies ?

waiting for your kind support

One possibility here: Use one for voice, one for R99 & HSPA data users but also handle voice users from other carrier due to congestion, another one as DC-HSPA carrier.

Greetings elmorabet,


You need to understand your market needs firstly, but usually in multi-carrier of 3 carriers one of them is used for voice and the remaining two for Data,

we don't have DC-HSDPA in our network , we have now dual carriers in our network and the priority in first carrier for R99 ( CS , PS ) , the second carrier for HSDPA we adjusted the priority by SPG and we changed the offset in idle to always lock on first carrier , so if we want to add another carrier for PS service so what we should do in all algorithms ?

Yes, it like my mobile network.

We are experiencing heavy congestion in WCDMA (channel elements and downlink channelization codes) more in the access many RRC connection blocks/failures.
The way we have configured is WDCMA for data mainly HSPA+, HSDPA, PS-R99 and do a direct retry from WCDMA to GSM for voice calls. Our immediate plans are to expand Channel Elements and add some sectors but also considering the second carrier.
What I want to know is what is the most effective configuration for the 2nd carrier option on each carrier.
I believe one will be the preferred carrier for reselection and idle mode.
The voice calls will maybe still redirected (direct-retry) to 2G
PS-R99 in the same carrier.
And maybe HSPA+ and HSDPA on the 2nd carrier.

Any recommendations or different configurations you have tried ?

There are not so many strategies while implementing second carrier. Actually you have to decide either to have HSDPA on one carrier or on both. Last solution is simple from parameters point of view, has more efficient cell load but HSDPA throughput impacted by R99 traffic. When you have HSDPA on both carriers the main challenge is to shift HSDPA traffic to second carrier as much as possible in order to have clear Ec/No on first carrier. This can be done using such feature as IFLS, HCS and etc. Some tunnig depends on hot spot or cluster deployment for second carrier.

thank you every body

Is there other strategies ?
