Method, device and user equipment for discontinuously receiving cell broadcast service messages

Abstract

The invention provides a method and device for discontinuously receiving cell broadcast service messages and user equipment (UE). The method comprises the steps that when it is detected that the UE enables a cell broadcast service, the cell broadcast service messages are received by means of a long DRX cycle and a short DRX cycle, the receiving condition of cell broadcast service scheduling messages is recorded, and the receiving proportion of receiving the cell broadcast service scheduling messages by means of the short DRX cycle and the receiving number of the received cell broadcast servicescheduling messages are counted in real time; when it is counted that the receiving proportion is higher than a first preset value and the receiving number reaches a second preset value, an adaptiveDRX cycle of receiving the cell broadcast service scheduling messages is calculated; and when the cell broadcast service scheduling messages are not received in the long DRX cycle later, the cell broadcast service scheduling messages are received by means of the adaptive DRX cycle, and if the cell broadcast service scheduling messages are not received by means of the adaptive DRX cycle in a presettime, the cell broadcast service scheduling messages are received by means of the short DRX cycle again. Accordingly, the power consumption of the UE can be reduced.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method, device and user equipment for discontinuously receiving cell broadcast service messages. Background technique [0002] In a mobile communication system, a user equipment (UE) receives a CBS (CellBroadcast Service, Cell Broadcast Service) message sent by the network side through a wireless interface. The CBS message is a type of short message, mainly including weather forecast, service information, etc. It is sent in the format of a CTCH (Common Traffic Channel, common traffic channel) data block. There are various types and contents of CBS messages on the network side, and not every type of CBS messages is required by the user. Frequent reception of CBS messages by the user will consume a large amount of power. In a wireless communication system, in order to save power consumption of the UE, a DRX (Discontinuous Reception, discontinuous reception) ...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, if the UE does not receive the CBS scheduling message within the default long DRX cycle, it needs to use at least one short DRX cycle to receive the CBS scheduling message until it successfully receives the CBS scheduling message, but if the short DRX cycle does not Adapting to the current network conditions, it may happen that the UE will wake up frequently and periodically to receive CBS scheduling messages, and the UE will consume a lot of power if it wakes up frequently and periodically
