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

Embodiment Construction

[0027] In the present invention, when the MTC group needs to be paged, the network element of the core network sends a paging message to the network element of the wireless access network, and the paging message at least carries the MTC group identification that needs to be paged; the network element of the wireless access network receives After the paging message, calculate a paging time according to the parameters in the received paging message, and send a paging message to the MTC device at the calculated paging time, and send the radio access network element to the MTC The paging message sent by the device at least carries the identity of the terminal to be paged or the identity of the MTC group.

[0028] To address the problems mentioned in the prior art, MTC services need to introduce some features different from traditional mobile communications, such as the group management feature. When this feature is activated, the MTC devices of the same user may be divided into a g...

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...
