Question: In a BSS applying Intra Domain Connection of RAN Nodes to Multiple CN Nodes, how are BVCI contexts allocated for cells supporting GPRS within one pool area?
Option 1: One BVCI context is allocated per pool area, shared among all SGSNs.
Option 2: One BVCI context is allocated for each cell supporting GPRS and for each associated SGSN within the pool area.
Option 3: A single BVCI context is allocated for all cells in a BSS, regardless of the number of SGSNs or pool areas.
Option 4: BVCI contexts are dynamically allocated based on traffic demand, not on a per-cell or per-SGSN basis.
Explanation: This is correct because when a BSS applies Intra Domain Connection of RAN Nodes to Multiple CN Nodes, it must have a separate BVCI context for each cell supporting GPRS and for each SGSN associated with the pool area that cell belongs to. This ensures proper resource allocation (radio resource capacity) and management (queue for LLC PDUs) for each SGSN-cell combination within the pool area.
