Question: What is the primary purpose of sending Gb Coverage Class Information from the BSS to the SGSN, and subsequently including it in the BSSGP Paging Request message or downlink BSSGP PDUs?
Option 1: To inform the SGSN about the MS's current location for billing purposes.
Option 2: To assist the GERAN in optimizing radio paging and radio resource assignment procedures based on the MS's reported coverage class.
Option 3: To enable the SGSN to prioritize data packets for transmission over the Gb interface based on coverage quality.
Option 4: To facilitate handover decisions by providing the SGSN with coverage information about neighboring cells.
Explanation: The correct answer reflects the primary purpose: to assist the GERAN in optimizing radio paging and the radio resource assignment procedure by providing the SGSN with the MS's reported Gb Coverage Class Information, enhancing paging towards the MS and ensuring successful radio resource assignments with required coverage enhancements.
