Hard blocking describes the situation when NO RADIO Resources are
assigned after the GPRS/EDGE/etc.. service request in Data Services and access to Data services is denied.
For instance, if we consider a case when a user requests resource for
Data Service access and no resources at all are assigned, this is deemed as Hard Blocking.

Soft blocking considered the scenarios that allocated channel numbers does not meet the MS multi time slot
capability after data service has established i.e. Soft blocking
where users are assigned a “PORTION” of the resources they request.

What is Hard Blocking & Soft Blocking? With example?

Soft blocking - when a cell is heavily loaded, the interference level increases because of many users. so the BTS might block any additional user (or call) so as to not add to more interference. remedy is to contain coverage or add more sites nearby congested site.

hard blocking - when a cell capacity gets limited when no more CEs are available. This off course is a hardware restriction. So a possible remedy is to add more CEs or contain coverage (optimization)
