Embodiment Construction

[0034] Embodiments disclosed herein relate to measurement techniques during cell reselection in mobile communications.

[0035] For reference and clarity, some technical terms in this paper are summarized as follows:

[0036] The high-priority frequency or RAT refers to: the frequency or RAT whose absolute value of priority is higher than the absolute value of priority of the current frequency.

[0037] The quality threshold Threshx refers to: a minimum signal quality requirement that can provide normal services on the Xth frequency or RAT. When the measured quality is lower than Thresh x , it means that the measurement object is not available at the current moment. Thresh on different frequency or RAT x Values ​​may vary.

[0038] In order to solve the problem of increased UE power consumption when the prior art cannot find a suitable high-priority frequency or RAT for a long time, the present invention provides a solution, in order to enable those skilled in the art to b...

Abstract

The invention discloses a measuring method for subdistrict reselection, comprising the following steps: user equipment (UE) receives information sent by a network side in leisure state after residing in a certain subdistrict, and the information contains information used for indicating each frequency and absolute values of the priority level of radio accessing technique (RAT); high priority level frequency or RAT is determined by utilizing the information, and the quality of the high priority level frequency or RAT is periodically measured every first present time; if a measuring result in a certain time does not satisfy a subdistrict reselection requirement, when the next measurement starts and when the quality of the high priority level frequency or RAT in a second present time does not satisfy a preset quality requirement, the first preset time is prolonged to be a third preset time from the beginning of the next measurement. The invention also discloses a device for realizing the method. The measuring period can be adjusted along with different frequencies or different quantities of the RAT. Under a certain condition, the measuring period is properly prolonged, thereby the measuring time is reduced, and the power consumption of the UE is decreased.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more specifically, relates to a measurement method and device for cell reselection. Background technique [0002] In the current LTE (Long Term Evolution, long-term evolution) solution, a priority-based inter-frequency and inter-RAT (Radio Access Technology, radio access technology) cell reselection measurement solution is determined. [0003] After the UE camps in a certain cell, it will detect whether there is a frequency or RAT with a higher priority than the current frequency or RAT, and measure the frequency and RAT regularly. When the measurement results of the frequency and RAT meet the reselection condition , cell reselection is performed. [0004] When the UE is in the idle state, how to perform regular measurement on high-priority frequencies or RATs, there is no complete specification scheme at present, and the specific details need to be further clarified. A...
