Signal strength measurement method and device

Abstract

The present invention relates to the technical field of mobile communications, and in particular to a signal strength measurement method and device, which can ensure that a Remote UE measures the signal strength of a link between the Remote UE and a ProSe UE-to-NW Relay. In the embodiments of the present invention, after establishing a connection with a remote device, a relay device can also send a second message, and thus the remote device can measure the signal strength of a link between the remote device and the relay device after receiving the second message, that is, after the connection is established between the remote device and the relay device, the relay device can also continue to send the second message, so that the remote device can continue to measure the signal strength between the remote device and the relay device, so as to serve as a basis for determining whether to re-select the relay device, thereby ensuring that the remote device can obtain a good quality of service, improving the utilization rate of a link with a higher quality, and also improving the system reliability.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and equipment for measuring signal strength. Background technique [0002] The Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (E-UTRAN), which has not been evolved, directly provides user equipment (User Equipment, UE) with network services, and can use device-to-device (device-to-device) device (D2D) technology discovers and connects to UEs that provide relay services. UEs that provide relay services are also called ProSe UE-to-NW Relay (ProSe UE-to-NW Relay). In this way, E-UTRAN Directly served UEs can obtain network services provided by E-UTRAN through relay. The UE receiving this relay service is also called remote user equipment (Remote UE). [0003] See figure 1 , is a schematic diagram of the remote device receiving the network service provided by the E-UTRAN through the relay device. From figure 1 It can be ...

Problems solved by technology

[0018] Whether it is mode A or mode B, it cannot guarantee that the ProSe UE-to-Network relay will continue to send messages to the Remote UE after establishing a connection with the Remote UE (Announcement message in Mode A, Response message in Mode B), then, in After the ProSe UE-to-Network relay establishes a connection with the Remote UE, the Remote UE can no longer measure the signal strength of the PC5 link. Even if the signal strength of the current PC5 link is weak, the Remote UE cannot know it, and it is impossible to reselect another ProSe UE-to-Network relay access, resulting in poor network quality accepted by the Remote UE, which affects the use of the network by the Remote UE. Even if there is a ProSe UE-to-Network relay that can provide strong signal strength, the Remote UE cannot Access, link utilization is low, and the overall network planning is unreasonable, which also leads to low system reliability
