Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0037] In the embodiment of the present invention, the LTE (Long Term Evolution, long-term evolution) system is taken as an example, and the terminal device is described by taking UE (User Equipment, user equipment) as an example. When the UE is in an idle mode, in order to save the battery life of the UE , the UE turns on the receiver to monitor the paging information only at the paging occasion in the DRX cycle. And if the network perfor...

Abstract

The invention discloses a method for reading system messages. The method comprises the steps of enabling a terminal device to receive paging messages comprising system message status indications in a discontinuous reception (DRX) period and comprise a device with a DRX period larger than a broadcast control channel (BCCH) modification period; according to the system message status indications in the paging messages, enabling the terminal device to confirm that a system message status is changed; enabling the terminal device to read and record the system messages corresponding to a current BCCH modification period or read and record the system messages corresponding to a next BCCH modification period adjacent to the BCCH modification period; and enabling the terminal device to communicate according to the read and recorded system messages. Accordingly, electric quantity of a battery can be saved, and user equipment (UE) can reduce power consumption.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and equipment for reading system messages. Background technique [0002] In order to reduce the power consumption of the terminal device and increase the standby time, when the terminal device is in idle state (idle) or when there is no data sending and receiving state, it will use DRX (Discontinuous Reception, discontinuous reception) mode to receive data, or use DTX (Discontinuous Transmission , non-continuous transmission) mode to send data. Among them, DRX is a method for extending battery life in wireless communication systems. The terminal device only needs to monitor the paging channel in the DRX group to which it belongs, and does not need to continuously monitor the paging channel, thereby saving battery power. . [0003] Due to the diversified development of terminal equipment, for example, terminal equipment applied in M2M (Machine to Machine, machine to machine) t...
