Paging message sending and receiving method and device

Abstract

The invention provides a paging message sending and receiving method and device, relates to the technical field of communication, and can reduce the influence of unsuccessful LBT monitoring on pagingmessage receiving of terminal equipment under the condition of an unlicensed spectrum. The method comprises: a terminal device receives paging indication information sent by a network device, the paging indication information being used for indicating whether at least one paging group needs to receive a paging message; and the terminal equipment determines the paging opportunity of receiving the paging message by the paging group where the terminal equipment is located according to the paging indication information. The method of the invention is used for sending and receiving the paging message under the unlicensed spectrum.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for sending and receiving paging messages. Background technique [0002] In a mobile communication system, paging messages are sent and received according to different service requirements. The purpose of the paging message is to inform the terminal equipment that there is information to be sent by the network, so that the terminal equipment can receive the information. When the network device sends a paging message, the terminal device can be in an idle state or a connected state. In the idle state, the terminal device needs to receive paging messages periodically, which is the paging cycle, but the specific paging occasion (PO) at which the terminal device receives the paging message is determined by the network system and the terminal device. The device is determined according to the protocol, and each terminal device has one and only ...

Problems solved by technology

At the beginning of PO2, the network device does not have the permission to send data, so the paging message for paging group 2 cannot be sent on PO2

[0004] At present, it is possible to increase the chances of paging messages to be sent successfully by increasing the paging opportunities, such as image 3 As shown, taking PO2 as an example, a paging opportunity PO2a is added to PO2, that is, when the terminal equipment of paging group 2 does not receive a valid paging message on PO2, paging group 2 continues to detect paging messages on PO2a, However, although this method increases the chance of successfully sending the paging message, it cannot avoid the situation that the base station has not obtained the permission to send data when the new opportunity is added, and it also increases the power consumption of the terminal device, especially when the network device does not send a paging message. When going out to paging messages, the two blind detections of the terminal equipment are invalid
