GPRS IMPROVEMENTS

Motorola BSC wise site count optimized GB link addition done ( 4Mbps to 8Mbps) Considerable improvement in GPRS throughput Data volume per user is more than Nortel Area E1 addition to individual BTSs done for 21sites.

3G COVERAGE OPTIMIZATION

All the newly on-air 3G site first round optimization completed

Data volume <500Mb sector were optimized w.r.t height, orientation and other parameters.

HSDPA data volume<500MB sectors is now ZERO

• Motorola Enabling 2nd E1 where TRX Count 12

and above

• Nortel PCU-BSC (AGPRS) link augmentation

required No spare PCUSN ports available Data volume per user is around 4MB

where as in Motorola 11Mb and ZTE 12Mb

Issues With 3G RNC overloading 1). Many new brand mobile phones are in automode. 2). BSNL activated 3G services to all the customers (all Prepaid SIM) by default. 3). If the 3G signal is sufficient for mobile to latch, the preference will be to 3G even though the user is not needed 3G/data services.4). The ZTE 3G RNC is overloaded in signaling plane and data plane.5).The signaling plane congestion causes

a).Outgoing call failureb).Not getting incoming call even though sufficient

coverage is in Phone.6).The Data plane congestion causes

a).Low data throughput7).Since the 3G network is overlay to the existing 2G, chances of getting latched to 3G is more, and many phones are attached to 3G.In Many mobile phones the present network (i.e 2G/3G) is not identifiable if the data service is not turned ON.8). The data service indication of 3G,H,H+ etc shows the mobile is in 3G network9).The signaling plane congestion can be reduced if we can push the 3G voice only subscribers to 2G (manually setting to 2Gonly), which will not cause any change in the voice service of the subscribers.
