Following is the description of 3 identified usage possibilities of ACC feature in live 2G-GSM/3G-WCMDA networks.
Figure 1 : Commercial Usage of ACC Feature
Normally the indoor sites allotted to corporate customers in an important location of a city is good enough to serve the customers (Corp. Mainly) during 9AM to 6PM. But most of networks where I have worked, the peak busy hour starts from 5~6 PM only and lasts up to 11 ~ 12 PM.During which the indoor coverage/IBS solution capacity unnecessarily wasted.Either they will be idle / used at minimum level.
Instead those corp. customer indoor sites should be a microcell with some external exposure. Corp. customers to have Class 15 (Example) SIM Cards. During morning hours these particular indoor sites can be configured to serve only those for CLASS-15 SIM cards.And in evening should be configured to allow all sim class. Such optimum usage will help operator to leverage those indoor BTS/NodeBs (i.e Infrastructure) . to handle those excessive traffic at Busy Hour.
Figure 2 : Disaster Recovery Usage of ACC Feature
During any disaster situation in certain countries it is evident from past experiences, it will be better to cease the public communications in order to speed up the recovery actions and streamline safety of public.Also helps to prevent unnecessary rumor based mis-behavior from public or from a particular segment of public.
So all BTS/NodeBs to be configured to serve the Class-1X which is allotted for Public Safety Organizations based on a pre-agreement.
This can be done for a particular geography/selected areas/cells in order to achieve quicker & un-interrupted recovery actions.
Figure 3 : Network Maintenance Usage of ACC Feature
The widely used model, doing all sort of maintenance activities like DT & Optimization etc while preventing customers from accessing the network through that particular BTS/s under maintenance and eventually avoids unnecessary disturbance to customers.
