Problems solved by technology

Different system measurement preparation delay is to use the time slot (GAP) measurement period defined by the network and the discontinuous reception (DRX, Discontinuous Reception) period to measure the LTE / GSM network inter-frequency information configured in the B1 / B2 event delivered by the network , select the appropriate inter-frequency information to report to the network, if the measurement preparation delay is too long, it will seriously affect the subsequent handover process

Abstract

The invention discloses a different system measurement optimization method and device, and user equipment. The method comprises steps that the user equipment UE receives an A3 / A4 event notice sent by a network side, and determines different frequency information of a to-be-measured first communication system from a notified A3 / A4 event; and the different frequency of the first communication system is subjected to scanning, and when the signal parameter of the different frequency of the first communication system cannot meet the A3 / A4 event according to determination, continuous scanning of the different frequency of the first communication system is carried out.

Description

technical field [0001] The present invention relates to carrier frequency measurement technology, in particular to a different system measurement optimization method and device, and user equipment. Background technique [0002] As the mobile communication system enters the 4G era, the coexistence of traditional 2G users and 3G and 4G users will exist for a long time. However, due to insufficient network coverage of Time Division Long Term Evolution (TD-LTE, Time Division Long Term Evolution), it may be necessary to switch to 2G such as GSM (Global System for Mobile Communication) during a VoLTE (Voice of Long Term Evolution) call. In the network, in order to ensure the success rate of the handover, the enhanced single radio voice call continuity (eSRVCC, Enhanced Single Radio Voice Call Continuity) inter-system measurement preparation delay is extremely important as a key parameter of the network. Different system measurement preparation delay is to use the time slot (GAP) ...
