Method and system for carrying out paging on MTC group

Abstract

The invention discloses a method for carrying out paging on a machine type communication (MTC) group. When a network element of a core network (CN) carries out paging on an MTC group, a paging message is sent to a network element of a radio access network (RAN), wherein the paging message at least carries a flag of an MTC group that needs to be paged; and after the RAN network element receives the paging message, the RAN network element calculates a paging time according to a parameter carried in the paging message and sends the paging message at the calculated paging time, wherein the paging message that is sent to MTC equipment by the RAN network element at least carries a terminal flag or an MTC group flag, wherein the terminal or the MTC group needs to be paged. Correspondedly, the invention also discloses a system for carrying out paging on an MTC group. According to the invention, when it is necessary to trigger a set of a large number of MTC devices to make communication with an MTC server, there is no need to individually carry out paging on the MTC devices one by one, so that the signaling number can be reduced and radio resources can be saved.

Description

technical field [0001] The present invention relates to the field of Machine Type Communication (MTC, Machine Type Communication), in particular to a method and system for paging an MTC group. Background technique [0002] The cellular wireless communication system is mainly composed of a core network (Core Network, CN), an access network (Radio Access Network, RAN) and terminals. Such as figure 1 As shown, wherein, the core network is responsible for non-access layer affairs, such as terminal location update, etc., and is the anchor point of the user plane; the access network includes base stations, or base stations and base station control, and the access network is responsible for access layer affairs (such as management of wireless resources), there can be physical or logical connections between base stations according to the actual situation, such as figure 1 The connection between base station 1 and base station 2 or base station 3, and each base station can be conne...

AI Technical Summary

Problems solved by technology

[0004] However, in the prior art, when it is necessary to trigger a large number of MTC devices to establish communication with the MTC server (for example, to notify the terminal device of remote meter reading to send the current month's record to the server), it is generally paging one by one. As a result, the signaling quantity of the paging message will be greatly increased, resulting in greater consumption of radio resources
