An application context relocation method and apparatus are provided. One example method includes: receiving first information from an application function entity, where the first information is for indicating to relocate an application context associated with the application function entity; and when an event that triggers relocation of the application context occurs, determining, based on the first information, to relocate the application context.

A user device, such as a vehicle, may find a suitable base station for communication according to a hailing message. A low-complexity hailing procedure, suitable for adding to 5G and 6G standards, is presented. The hailing message may be a brief code indicating that it is a hailing message, and therefore solicits a reply. The hailing message may further include the identification or location of the user device, and/or an indication of which type of entity is being sought, such as a base station. The base stations that receive the hailing message can reply after a calculated delay time, such as a longer delay time if the received amplitude is weak, so that the user device can select whichever base station has the best received signal. Alternatively, the user device can select the base station with the largest received amplitude of the reply message.

The present disclosure relates to an electronic device, a radio communication method, and a computer-readable storage medium. The electronic device of the present disclosure for use in a vehicle is configured to: receive a message, the message comprising a validity time of the message and a validity range of the message; and determine, on the basis of the validity time of the message and of the validity range of the message, whether to forward the message. The use of the electronic device, the radio communication method, and the computer-readable storage medium of the present disclosure optimizes an exchange process for vehicle-related information, thus reducing overhead and delays to the greatest extent, and thereby increasing communication efficiency.

The technical problem of optimizing power consumption of paired user devices is addressed by disabling and resuming short range wireless communication components of the paired user devices. The disabling and resuming of the short range wireless communication components may be determined based on a comparison of a distance between the paired user devices and a threshold distance. The threshold distance may be adjusted by a machine learning model according to user profiles associated with the paired user devices. The distance between the paired user devices may be determined based on location data of the paired user devices. The location data may be obtained by global positioning systems (GPS) mounted on the paired user devices. The location data may be communicated between the paired user devices via a messaging server.

A computer-implemented method includes receiving, at a mobile device, geographical coordinates defining one or more alert areas associated with a wireless emergency alert over a wireless communication network, and comparing, at the mobile device, the current location of the mobile device with the received coordinates to determine if the mobile device is within the alert area(s). If the mobile device is within the alert area(s), the method further comprises applying a mapping application or other application on the mobile device to construct a map of the alert area(s) based on the coordinates, determine the location of the mobile device with respect the alert area(s), and display the map indicating the location of the mobile device with respect to the alert area(s) at a display interface of the mobile device.

A communication network encrypts a first portion of a transaction associated with point-to-point communications using a point-to-point encryption key. A second portion of the transaction associated with end-to-end communications is encrypted using an end-to-end encryption key.

An electronic healthcare system for delivering medical services is described. The electronic healthcare systems can includes modules for accessing patient electronic medical records and ordering medical services. In response to a medical service order, a cost estimation and notification module can receive information associated with the medical service order. The cost estimation and notification module can determine the patient cost responsibility and quickly notify the patient of the costs. The patient can use the determined cost information to decide whether to move forward with the ordered medical tests.
