Autonomous neighbor relation detection and handover optimization in LTE

Evaluation of the Automatic Neighbor Relation Function in a Dense Urban Scenario

“…The work closest to our results is [9], where some of the authors were involved as well. The authors presented an analysis of the ANR convergence time for cells layed out on a hexagonal grid.…”

“…The authors presented an analysis of the ANR convergence time for cells layed out on a hexagonal grid. ECGI measurements were modeled in the same way, but in [9] the A4 event was not included. Instead, the A3 event was used as trigger for both handovers and the ANR function.…”

An effective cross-layer designed packet scheduling, call admission control, and handover system for video streaming services over LTE network

“…(19) and (20). In other words, when handover occurs, if the target eNodeB does not have wireless network resources to support both existing UEs and the transferred UE, the QoE state of the target eNodB may be seriously deteriorated after the handover is complete.…”

“…However, when most of the traffic has a real-time variable rate, the priority-based admission decision is unfair and not useful.Efficient handover algorithms have also been researched. In[19,20], Aziz et al proposed a simple ICIC (Inter Cell Interference Coordination) scheme for determining an optimized handover parameter to avoid the radio link failure while maintaining low handover rates. However, the proposed ICIC scheme considers that the target cell always has resources available for the incoming UE, making a simple ICIC scheme not applicable in a real-world LTE system.…”

Updating Neighbour Cell List via Crowdsourced User Reports: A Framework for Measuring Time Performance

“…In the literature, it is usually assumed that neighbourhood information may be instantaneously acquired [7][8][9][10][11][12][13]; that is, the time is considered negligible. In fact, this assumption may often not be valid, either because it is necessary to listen to the channel long enough to get a high-confidence estimation or because hidden nodes/second-hop NCLs need to be known as well, and thus it is necessary to use communication with users or other nodes to obtain such information.…”
