TL;DR: In this article, the authors proposed a method to determine when to redirect and handover a mobile terminal that is still communicating on an adjacent carrier with a border base station within an overlay area but is within the coverage area of the base station in the underlay area.
Abstract: To avoid interference with the reverse link of a base station within an underlay area, a described method determines when to redirect and handover a mobile terminal that is still communicating on an adjacent carrier with a border base station within an overlay area but is within the coverage area of the base station in the underlay area. The method determines that redirection and handover to the base station in the underlay area should occur when together: (1) the power being received on the downlink from the base station in the underlay area exceeds the power being received on the downlink from the border base station within the overlay area by a first predetermined threshold that indicates that the mobile terminal is at the border of the overlay area; and (2) the sum of the power being received on the downlink from the underlay base station plus the power of the signal being transmitted by the mobile terminal to the base station within the overlay area is greater than a second predetermined threshold that indicates that the power being received by the base station in the underlay area from the transmitting mobile terminal can interfere with the operation of that base station.

TL;DR: A Fuzzy-Based Multi-Interface System (FBMIS), where each node is able to switch from cellular to Ad hoc and vice versa and the main difficulty is how to choose the right interface in order to guarantee a minimal usage of network resources and at the same time keeping the communication performance in a satisfactory level.
Abstract: Several solutions have been proposed for improving the Quality of Service (QoS) in wireless cellular networks, such as Call Admission Control (CAC) and handover strategies. However, none of them considers the usage of different interfaces for different conditions. In this work, apart from using only Base Stations (BSs) as an important device of cellular networks, we propose a multi-interface approach in order to avoid BS overloads and improve the QoS of wireless communications. We propose a system, where each node is equipped with two interfaces: the traditional cellular network interface and Mobile Ad hoc Networks (MANET) interface. The main difficulty for this system is how to choose the right interface in order to guarantee a minimal usage of network resources and at the same time keeping the communication performance in a satisfactory level. For this purpose, in this paper we propose a Fuzzy-Based Multi-Interface System (FBMIS), where each node is able to switch from cellular to Ad hoc and vice versa. We consider three input parameters and one output parameter. From the simulation results, our system shows a good performance.

TL;DR: In this article, a decision is made whether one or more of the mobile terminals is likely to request a handover of its respective connection to a neighboring base station based on the current load, the likelihood of requesting handover, and the connection activity level determined for the respective connection.
Abstract: A control signal data processing load associated with mobile terminals currently having a connection with a radio access network is regulated. The connection is terminated when the control processing cost for maintaining the connection exceeds the benefit of maintaining the connection to achieve shorter access latency. A connection activity level is determined for current connections between multiple mobile terminals and a base station. A current data processing load in the base station associated with the mobile terminal control signaling is calculated. A decision is made whether one or more of the mobile terminals is likely to request a handover of its respective connection to a neighboring base station. Based on the current load, the likelihood of requesting handover of the respective connection, and the connection activity level determined for the respective connection, a decision is made whether to terminate the respective connection.

TL;DR: In this article, the authors proposed a handover method in a next-generation mobile communication system, where a terminal operates in two modes to support mobility on the IP-based networks, and it performs a handoff procedure by configuring a layer below the MAC to a new AS without allocating the IP at the handover state when it is in the active state to thus minimize handover delay time.
Abstract: Disclosed is a handover method in a next-generation mobile communication system. When a terminal is in the idle state, an IP is reallocated according to a process of mobile IPs to perform a location registration process, and when the terminal is in the active state, it operates according to a procedure of a mobile communication network. Therefore, the terminal operates in two modes to support mobility on the IP-based networks, and it performs a handover procedure by configuring a layer below the MAC to a new AS without allocating the IP at the handover state when it is in the active state to thus minimize handover delay time.

TL;DR: The structure and function of change-of-shift reports are focused on and the events that occur within them are listed, describing the locations of the handover process and the mode of communication involved.
Abstract: The nurse-to-nurse handover is not taught formally during training, yet it is one of the most important rituals of the nursing shift. This article focuses on the structure and function of change-of-shift reports and lists the events that occur within them, describing the locations of the handover process and the mode of communication involved. The problems that can occur during handover are discussed and solutions are proposed.
