A method of evaluating performance of a communication apparatus for a vehicle includes performing communication with a base station, monitoring a fail event and determining a fail event score based on results of the monitoring, monitoring an attempt of a handover and determining a pingpong handover (PPHO) score based on results of the monitoring, monitoring a retention time within a shadow area and determining a service score based on results of the monitoring, and determining a final score based on the fail event score, the PPHO score, and the service score.

The described technology is generally directed towards cellular network tuning using secondary system feedback. Network equipment can monitor both network performance and secondary system feedback indicative of secondary equipment performance. The secondary equipment can comprise customer manufacturing, processing, or other equipment. The secondary equipment performance can be correlated with network performance such as by correlating secondary equipment performance degradations with degradations of one or more network performance indicators. Network parameters can be adjusted in view of the observed correlation, to produce performance improvements of the secondary equipment.

A method and apparatus for fast cell selection by a mobile wireless device. The mobile wireless device detects when a first wireless cell fails a set of stored suitability criteria and searches for and locates a set of candidate wireless cells to associate with. The mobile wireless device measures at least one received signal metric for each candidate wireless cell in the set of candidate wireless cells. When a candidate cell in the set of candidate wireless cells is identically the first wireless cell, the mobile wireless device evaluates the suitability of the candidate wireless cell using the stored set of suitability criteria for the first wireless cell and the measured at least one received signal metric for the candidate wireless cell. The mobile wireless communication device associates with the candidate wireless cell when the candidate wireless cell meets the stored set of suitability criteria.

Techniques are disclosed for determining a specific velocity of a device attached to a wireless network. The specific velocity can be determined using a handover count of the base station boundary transitions over a time window and/or using a set of sojourn time samples that each denote the duration the device remains in the zone of a particular base station. Techniques operate effectively in cellular networks having high base station densities. The specific velocity estimates may be inputs to components on the device or network to adjust a local device function or performance behavior.

This application provides a communication method and apparatus. A terminal may obtain configuration information of a wake-up signal of a camped cell and configuration information of a wake-up signal of another cell from a network device, to receive the wake-up signal of the camped cell and/or the wake-up signal of the another cell based on a signal measurement requirement of the terminal. In this way, power consumption of the terminal is reduced, and a signal of the camped cell and/or a signal of the another cell are/is measured. This can avoid a case that a main radio frequently wakes up to measure cell quality, to reduce energy consumption of the terminal.

A computer-implemented method for automatically detecting cross-connected cells in communication network. The method includes obtaining first cell data of source cell within communication network; determining effective area of source cell using first cell data; classifying each neighbouring cell of source cell into one of: a first group, a second group, based on location of neighbouring cell; calculating share of handover events from source cell to neighbouring cells in first group using first cell data; and when share of handover events from source cell to neighbouring cells in first group lies below first threshold, filtering out neighbouring cell(s) from amongst second group with which handover events of source cell lies above second threshold and determining source cell to be cross-connected cell when: direction of filtered cell(s) is opposite to direction of the source cell; and/or effective area of filtered cell(s) does not overlap with effective area of source cell.

A method includes: operating, by a source radio access network (RAN) node serving a user equipment (UE), in a bistatic mode for a sensing service provided by one or more components of a core network; and based on a handover decision that switches the UE to a target RAN node, transmitting, by the source RAN node, sensing service information to one of the following: the target RAN node, or an access and mobility management function (AMF) of the core network. The sensing service information includes at least one of the following: at least one sensing session identifier corresponding to at least one sensing session for the serving service, a sensing resource configuration for the sensing service, a sensing session configuration for the sensing service, or a sensing data reporting configuration for the sensing service.

There is provided mechanisms for improving performance in a wireless communications network. A method is performed by a network node. The method comprises acquiring an identification of a set of cells for which adjustment is needed. The method comprises identifying a reason for the adjustment and improvement possibilities of the set of cells using at least one indicator. The reason and the improvement possibilities define a combination of which parameters and network nodes that could be adjusted. The method comprises determining an improvement action for the set of cells by jointly optimizing the combination of parameters and network nodes based on the reason and the improvement possibilities.

A method of performing roaming and handover load balancing in a multicell wireless communication network that comprises one or more base stations, each base having a number of call slots to communicate with wireless terminals. The method includes receiving, at a terminal, a broadcast from a base, of the one or more bases, providing capacity information for the one or more bases. The capacity information comprises terminal localization status information and active call handover status information for the one or more bases. The method also includes storing the capacity information in a database at the terminal. The method further includes receiving a roaming or handover request based on signal strength and/or link quality directing the terminal to roam or handover a call to a target base; and overriding the roaming or handover request, to prevent roaming or handover to the target base, based on the stored capacity information.
