Section: 12.2.7 Issues in the network with partial support of the feature
Content: The Load Control feature should be supported homogenously across all the SGWs and PGWs in the network. Not supporting this feature homogeneously across the SGWs and PGWs may result in poor load balancing in the network such that the SGWs or PGWs not supporting the feature may operate near their maximum capacity (thus being more vulnerable to overload conditions) while SGWs or PGWs supporting the feature have free capacity. The Load Control feature should be supported homogenously across all the MMEs, S4-SGSNs, ePDGs and TWANs. However, use of the feature when not all of these nodes support the feature may not necessarily create a problem since the load may remain fairly balanced across the SGWs and PGWs assuming that the network imbalance caused by the non-supporting node may get rectified by the supporting nodes making use of dynamic load information while selecting the SGWs and PGWs.
