“…In order to compare the performance of the TBDUOS scheme and the performance of conventional schemes, we also simulate both the cell-cluster based traffic offloading (CCTO) scheme of (Wang, 2010) and the utility function based traffic offloading (UFTO) scheme of (Yang, 2012;Yang, 2014).…”

“…In (Yang, 2012;Yang, 2014), the authors design the cell load based utility function to adjust HO off , in order to offload edge users efficiently. In (Wang, 2010), the neighbouring cell with the lowest load is chosen as the assistant cell in sequence, then the heavily loaded cell shifts users to RSs in assistant cells, thus balancing the traffic distribution evenly. In , the load balancing objective is to avoid a cell serving too many users via broadcasting and considering the number of users served by each cell's RS.…”

This paper proposes a telecom big data based user offloading self-optimisation (TBDUOS) scheme. Its aim is to assist telecom operators to effectively balancing the load distribution with achieving good service performance and customer management in heterogeneous relay cellular systems. To achieve these objectives, in the cell-level offloaded traffic analysis stage, the optimal offloaded traffic is calculated to minimise the total blocking probability. In the user-level offloading stage, the user portrait is drawn and the K-MEANS algorithm is employed to manage the users clustering in the heavily loaded cell, and finally shifting users to assistant cells. Simulation results show the TBDUOS scheme can effectively reduce the handover failure and call dropping of specific users, especially voice/stream users, high consumption users, high level users. The TBDUOS scheme can also reduce the blocking probability.

“…In the process of resource allocation, if the traffic load of a certain cell is overloaded, it will not provide cooperating service for other cell-edge UEs from other CoMP cells. So when considering the CoMP cell selection, the traffic load of the cells was taken into consideration in [7]. Reference [8] takes into account the reference signal quality of service, load and signaling delay for cooperating cell selection.…”

An Efficient Method for Managing CoMP Cooperating Set Based on Central Controller in LTE-A Systems

“Authorized Shared Access” (ASA) is a spectrum management policy which enables the secondary system to opportunistically utilize the licensed spectrum of the primary systems. In the coexistence of LTE-A system with primary systems, one of the constituent cells of the CoMP cooperating set may be affected because it has to vacate the ASA frequency for it overlaps with the protected area of the primary system. As a result, the CoMP cooperating set will be changed, and the operation of the CoMP can’t be continued execution. In this case, the UE’s QoS can’t be guaranteed and even the UE experiences call drop when using the traditional method. In this paper, by utilizing a central controller, we propose an efficient method for managing CoMP cooperating set on the ASA spectrum. The change information about the affected cell is sent to the serving cell of the CoMP through the central controller in advance. Then, the serving cell may reselect a new CoMP cooperating set or determine CoMP information indicating whether the CoMP cooperating set will be continued based on this change information, which effectively ensures continued execution of CoMP and the UE’s QoS. Simulation results show that the proposed method can provide better performance compared with the traditional method.

Abstract. The problem of non-uniform traffic demand in different cells of a cellular network may lead to a gross imbalance in the system performance. Thus, the users in hot cells may suffer from low throughput. In this paper, an effective and simple load balancing scheme CAC_DPLB_MCN is proposed that can effectively reduce the overall call blocking. This model considers dealing with multi-media traffic as well as time-varying geographical traffic distribution. The proposed scheme uses the concept of cell-tiering thereby creating fractional frequency reuse environment. A message exchange based distributed scheme instead of centralized one is used which help the proposed scheme be implemented in a multiple hot cell environment also. Furthermore, concept of dynamic pricing is used to serve the best interest of the users as well as for the service providers. The performance of the proposed scheme is compared with two other existing schemes in terms of call blocking probability and bandwidth utilization. Simulation results show that the proposed scheme can reduce the call blocking significantly in highly congested cell with highest bandwidth utilization. Use of dynamic pricing also makes the scheme useful to increase revenue of the service providers in contrast with compared schemes.
