The present disclosure relates to a communication technique for converging IoT technology with a 5G communication system for supporting a higher data transfer rate beyond a 4G system, and a system therefor. The present disclosure can be applied to intelligent services (e.g., smart homes, smart buildings, smart cities, smart or connected cars, health care, digital education, retail business, and services associated with security and safety) on the basis of 5G communication technology and IoT-related technology.

This application provides example communication methods and example communications devices. One example method includes sending, by a terminal device, a notification message, where the notification message is used to notify a network device of information about a first radiation intensity of the terminal device when the terminal device uses at least one of a first beam or a first antenna panel. The terminal device can then send data by using at least one of a second beam or a second antenna panel, where a second radiation intensity of the terminal device when the terminal device sends the data by using the at least one of the second beam or the second antenna panel is less than the first radiation intensity of the terminal device.

There is provided an apparatus, said apparatus comprising means for providing a first registration request from a user equipment to a first visited network for a first network slice provided by the first visited network and providing a further registration request from the user equipment to at least one second visited network for at least one second network slice provided by the second visited network, wherein the first network slice and at least one second network slice are mapped to subscribed network slices in a home network and the at least one second network slice is not provided by the first visited network.

Various example embodiments relate to energy efficient paging of dual-mode user equipment (UE). A UE may receive paging configuration information from a first network. The paging configuration information may comprise paging parameter(s) for monitoring a paging channel of a second network. Based on the received paging configuration information, the UE may monitor the paging channel of the second network and receive a paging message associated with the first network from the second network. In response to receiving the paging message from the second network, the UE may transmit a paging response to the first network. Apparatuses, methods, and computer programs are disclosed.

A system for exchanging GPS or other position data between wireless devices for purposes of group activities, child location monitoring, work group coordination, dispatching of employees etc. Cell phones and other wireless devices with GPS receivers have loaded therein a Buddy Watch application and a TalkControl application. The Buddy Watch application communicates with the GPS receiver and other wireless devices operated by buddies registered in the users phone as part of buddy groups or individually. GPS position data and historical GPS position data can be exchanged between cell phones of buddies and instant buddies such as tow truck drivers via a buddy watch server. Emergency monitoring services can be set up with notifications to programmable individuals in case an individual does not respond. Positions and tracks can be displayed. TalkControl simplifies and automates the process of joining talk groups for walkie talkie services such as that provided by Nextel.
