Embodiment 1

[0121] like image 3 shows a flow chart of the paging method provided by Embodiment 1 of the present invention, as shown in image 3 As shown, the method may include:

[0122] 301. A base station receives a paging message of a user equipment.

[0123] Preferably, the base station can receive the paging message of the user equipment sent by the MME through S1; or receive the paging message of the user equipment sent by the SGSN through the Gb interface.

[0124] Wherein, the paging message includes the user identification of the user equipment, and is used to wake up the user equipment in an idle state.

[0125] 302. The base station calculates a paging location of the user equipment according to the user identifier of the user equipment.

[0126] Wherein, the paging location is used to send paging scheduling information; the paging scheduling information is used to indicate the sending location where the base station sends the air interface paging message to the user equipm...

Embodiment 2

[0155] Figure 5 shows a flow chart of the paging method provided by Embodiment 2 of the present invention, as shown in Figure 5 As shown, the method may include:

[0156] 501. The user equipment receives the paging scheduling information sent by the base station at the paging location.

[0157] Wherein, the paging scheduling message is encoded according to the modulation and coding format MCS corresponding to the coverage level of the user equipment, and is used to indicate the location of the air interface paging message sent by the base station to the user equipment, and the location of the user equipment The coverage level is reported by the user equipment to the MME / SGSN, and issued by the MME / SGSN to the base station;

[0158] The air interface paging message includes a paging message record list, and the paging message record list includes at least one paging message of the user equipment, and the corresponding relationship between the paging message of the user equi...

Embodiment 3

[0171] Image 6 The flow chart of the paging method provided by the embodiment of the present invention, such as Image 6 As shown, the method may include:

[0172] 601. A core network device sends a paging message of a user equipment to a base station.

[0173] Preferably, the core network device sends the paging message of the user equipment to the base station through the S1 interface or the Gb interface.

[0174] Wherein, the paging message is used to wake up the user equipment in an idle state.

[0175]602. The base station calculates the paging location of the user equipment.

[0176] Wherein, the paging position is determined by the paging superframe and the paging opportunity, and is used to send paging scheduling information; the paging scheduling information is used to indicate the sending position of the base station to send the air interface paging message to the user equipment.

[0177] Preferably, the base station can calculate the paging superframe according...

Abstract

The invention discloses a paging method, device and system, which relate to the technical field of wireless communication, and send messages to user equipment according to the coverage level of user equipment, so that user equipment in different coverage areas can obtain paging messages, and at the same time reduce retransmission Number of paging messages. The method provided by the present invention includes: the base station receives the paging message of the machine-to-machine user equipment; calculates the paging position of the user equipment; determines the coverage level of the user equipment; The device sends an air interface paging message, and sends paging scheduling information at the paging location; wherein, the paging scheduling information is used to indicate the sending location of the air interface paging message, and the air interface paging message includes the The paging message of the user equipment.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a paging method, device and system. Background technique [0002] Machine-to-machine (English: Machine to Machine, abbreviation: M2M) communication is a kind of data communication including one or more machine devices without human interaction. Among them, the machine devices (such as sensors, electricity meters, water meters, Alarm equipment) may be referred to as user equipment. Due to the large number of user equipment in the M2M communication system and most of them are powered by batteries, it will be a huge workload for the M2M system to replace the battery once. In view of this, people hope that the user equipment has lower power consumption and longer standby time. time. In order to meet this characteristic of the user equipment, in the idle mode of the M2M communication system, the base station periodically sends paging messages to the user equip...
