Position management method of terminal, paging method, device and terminal

Abstract

The invention provides a position management method of a terminal located outside network coverage, a paging method, a device and the terminal. The terminal can carry out D2D communication with a relay terminal, wherein the relay terminal is located within the coverage range of a network; the position management method of the terminal comprises the following steps: granularity information for position management is obtained by the terminal; the granularity information is used for marking the position of the terminal; the terminal reports the position information of the terminal to a network side server according to the granularity information and whether the marking information of the relay terminal is obtained, so that the network side server can manage the position of the terminal. According to the technical scheme, the position information of the terminal located outside the network coverage can be managed, so that paging operation can be carried out on far-end UE (User Equipment) within a designate range, and the condition that excessive wireless resources are occupied due to broadcasting a paging message in the whole network when the far-end UE is subjected to paging is avoided.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular, to a location management method for a terminal out of network coverage, a location management device for a terminal out of network coverage, and a method for paging a terminal out of network coverage A method, a device for paging a terminal outside network coverage, and a terminal. Background technique [0002] 3GPP Release 12 has introduced the discussion of partial coverage scenarios, that is, two or more terminals performing D2D (Device-to-Device, device-to-device) communication, some are located within the network coverage, and some are located outside the network coverage. The location management of the terminals within the network coverage can be implemented by the network side, while the location management of the terminals outside the network coverage has not been defined by 3GPP. Such as figure 1 Shown is a schematic diagram of a partial coverage scenario....

AI Technical Summary

Problems solved by technology

However, in certain scenarios, the network side still needs to know whether the remote UE exists, or needs to trigger the remote UE to initiate D2D communication through paging, such as starting the selection and connection process of the relay UE, while the existing scheme However, the location information of the remote UE cannot be managed

If the network side needs to page the remote UE through the relay UE, the result of the lack of location management information is that the network needs to broadcast paging messages throughout the network. As the number of terminals continues to increase, this will undoubtedly cause a huge wireless waste of resources

[0004] Therefore, how to manage the location information of terminals outside the network coverage and avoid broadcasting paging messages on the entire network when the remote UE needs to be paged, resulting in the occupation of more wireless resources has become a technical problem to be solved urgently
