The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE).

A method of setting a handover parameter includes receiving, from a serving evolved NodeB (eNB), cell type information indicating eNB types of the serving eNB and eNBs adjacent to the serving eNB, and mobility information of the UE, detecting types of the serving eNB and a target eNB based on the cell type information, and setting a Time-To-Trigger (TTT) applied, the mobility information of the UE, and a received signal strength for the serving eNB.

A first base station in a network initiates handover of a wireless device in connected mode to a second base station. The first base station initiates a handover employing a first criterion, if the wireless device is in an active call from a first call category with the first base station. The first base station initiates a handover using a second criterion, if the wireless device is not in an active call from a first call category with the first base station.

A method and system for dynamically managing a downlink coverage threshold that is used for triggering handover processing of a user equipment device (UE). The downlink coverage threshold is dynamically decreased upon invoking of uplink Transmission Time Interval (TTI) bundling service for the UE.

Distribution of traffic to cells in a communication network can be controlled. A distribution management component (DMC) can determine overall device traffic throughput for cells of a sector that satisfy a defined traffic throughput criterion relating to a harmonic mean of the device traffic throughput for the cells to desirably enhance or maximize the harmonic mean of the overall device traffic throughput. Based on the overall device traffic throughput for the cells, the DMC can determine whether to adjust a characteristic associated with a cell of the cells to facilitate adjusting distribution of device traffic among the cells of the sector to achieve desirable load balancing of traffic by the sector and in the network. Load balancing can be achieved by controlling respective parameters with regard to communication devices that are in idle mode or connected mode to facilitate directing communication devices and associated traffic to desired cells.

Embodiments of the present invention disclose a terminal behavior triggering method and a terminal. The method includes: detecting an environment parameter of a terminal and a terminal status parameter of the terminal; determining a target situation event based on the environment parameter and/or the terminal status parameter; and if the environment parameter meets a first preset condition, and the terminal status parameter meets a second preset condition, triggering a terminal behavior corresponding to the target situation event.

Disclosed is a method comprising evaluating a survival time status of a terminal device, determining a handover command transmission based at least partly on the survival time status, and transmitting the handover command to the terminal device based on the determining.

Methods and apparatus are provided for UE-triggered handover and early preparation with coexistence of the network-triggered handover. In one novel aspect, the UE is configured early measurement report configuration, receives an early handover command from the serving base station with a handover candidate cell list, monitors handover triggering conditions for each candidate cell on the handover candidate cell list based on a UE-triggered handover configuration and performs the UE-triggered handover to a candidate cell when the corresponding triggering condition is met for the candidate cell. In one embodiment, the UE receives a network-triggered handover command to a target cell, suspends the UE-triggered handover configuration and performs the network-triggered handover to the target cell. The UE discards the UE-triggered handover configuration upon success of the network-triggered handover and resumes the UE-triggered handover configuration upon failure of the network-triggered handover.

Disclosed is a method comprising receiving an indication indicating one or more time windows, during which a handover is allowed to be initiated; evaluating whether one or more conditions for the handover are fulfilled within the one or more time windows; and initiating the handover during one of the one or more time windows, if the one or more conditions are fulfilled.

Apparatuses, methods, and systems are disclosed for WLAN selection. One apparatus includes a transceiver and a processor coupled to the transceiver. The processor is configured to cause the apparatus to receive WLAN selection/routing signaling from a serving PLMN and to identify whether the apparatus is connected to a WLAN. The processor is further configured to cause the apparatus to determine whether to accept the WLAN selection/routing signaling based on whether the apparatus is connected to a WLAN and/or a based on a device configuration. In various embodiments, the WLAN selection/routing signaling is a LWA command, a RCLWI command, or a LWIP command.

Predicting mobile station migration between geographical locations of a wireless network can be achieved using a migration probability database. The database can be generated based on statistical information relating to the wireless network, such as historical migration patterns and associated mobility information (e.g., velocities, bin location, etc.). The migration probability database consolidates the statistical information into mobility prediction functions for estimating migration probabilities/trajectories based on dynamically reported mobility parameters. By example, mobility prediction functions can compute a likelihood that a mobile station will migrate between geographic regions based on a velocity of the mobile station. Accurate mobility prediction may improve resource provisioning efficiency during admission control and path selection, and can also be used to dynamically adjust handover margins.
