Problems solved by technology

However, with the emergence of HSPA technology, the transmission power of UE at this time includes not only DPCCH and DPDCH power, but also HS-DSCH dedicated physical control channel (Dedicated Physical Control Channel for HS-DSCH, HS-DPCCH for short), enhanced dedicated physical control channel (E-DCH Enhanced Dedicated Transport Channel Dedicated Physical Control Channel, referred to as E-DPCCH), enhanced dedicated physical data channel (E-DCH Enhanced Dedicated Transport Channel Dedicated Physical Data Channel, referred to as E-DPDCH) power, so the total transmission power of the UE is used It cannot accurately reflect whether the UE is power limited

Abstract

The embodiment of the invention discloses a method for detecting the power constraint of user equipment (UE). The method comprises the following steps: the measurement request message of PE-DPDCH is sent, wherein the measurement request message contains a request for measuring PE-DPDCH, a PE-DPDCH upper threshold and a first time, or / and PE-DPDCH lower threshold and a second time; a measurement report measured according to the measurement request message is received, when the measurement request message contains the upper threshold and the first time and when the time that the measurement report containing PE-DPDCH value is continuously above the upper threshold is more than the first time, first message is sent, or when the measurement request message contains the lower threshold and the second time, and when the time that the measurement report containing PE-DPDCH value is continuously above the upper threshold is more than the second time, second message is sent; and if the measurement report contains the first message, the power of UE is not constrained, and if the measurement report contains the second message, the power of UE is constrained. By adopting the embodiment of the invention, whether the power of UE is constrained can be accurately judged.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for detecting power limitation of user equipment UE. Background technique [0002] In a mobile communication system, the power limitation of a user equipment (User Equipment, UE for short) means that the power limitation of a UE in a connected state will affect the quality of an uplink signal transmitted by the UE. When the network obtains that the UE is in a power-limited state, it may perform a Quality of Service (Quality of Service, QoS for short) handover to improve the service QoS of the UE. For example, when the UE is performing NRT services, the speed reduction of BE services can be performed; when the UE is using Adaptive Multi-Rate (Adaptive Multi-Rate, referred to as AMR) technology to transmit voice services, reduce the encoding rate of AMR services; or The UE performs inter-frequency handover and inter-system handover.
