Implementation method, device and user equipment for inter-frequency measurement and inter-system measurement

Abstract

The present invention provides an implementation method, device and user equipment for inter-frequency measurement and inter-system measurement. The method includes: judging whether the UE enters the short DRX mode in the RRC connected state; when the UE enters the short DRX mode in the RRC connected state, judging whether the network starts to measure the inter-system measurement; when the network starts to measure the inter-system measurement , judge whether the signal coverage of the LTE cell where the UE resides is lower than the predetermined threshold; when the signal coverage of the LTE cell where the UE resides is lower than the predetermined threshold, use the idle time except the measurement gap configured by the network in the inactive period Inter-frequency measurement is performed, and inter-system measurement is performed using the measurement gap configured by the network. The invention can make full use of the inactive period of short DRX in the connected state to perform inter-frequency measurement, utilize the measurement gap configured by the network to perform inter-system measurement, speed up the measurement reporting of the inter-system without affecting the inter-frequency measurement, and prevent the UE from falling off. talk.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular, to a method, device and user equipment for realizing inter-frequency measurement and inter-system measurement. Background technique [0002] In an LTE (Long Term Evolution, Long Term Evolution) wireless network, in the RRC_CONNECTED (RRC connection) state, the UE (User Equipment, user equipment) measures the RSSI (Received Signal Strength Indication, Received Signal Strength Indication, Received Signal Strength Indication) of the serving cell and adjacent LTE cells Signal strength indicator), RSRP (Reference Signal Receiving Power, reference signal receiving power), RSRQ (Reference Signal Receiving Quality, reference signal receiving quality) related indicators are measured and reported to the network, and the signal quality measurement of cells in different systems is also configured and reported to the network. , the measurement result has a direct impa...

AI Technical Summary

Problems solved by technology

In the prior art, the UE performs inter-frequency measurement and inter-system measurement configuration as follows: figure 1 As shown, it can be seen that in the RRC_CONNECTED short DRX mode, the UE only uses the periodic measurement gap allocated by the network for measurement, and cannot fully measure the different systems, and cannot report the measured values ​​of the different systems in time. If the LTE coverage in the current network environment Relatively poor, UE cannot SRVCC in time when performing VOLTE telephone service, and it is prone to call drop
