Embodiment Construction

[0029] In the embodiment of the present invention, information transmission to the MTC terminal is realized by sending a paging message to a group that needs to receive the message. Compared with the traditional paging method, one-to-one sending is no longer required, which saves network resources. Compared with the MBMS method, the realization of the paging message is more flexible, and is not limited by the fixed format and length.

[0030] This embodiment includes a RAN group (RAN group) and an MTC group (MTC group). RANgroups can be divided according to services, operations, and MTC equipment types. MTC groups can be divided according to MTC equipment types and regions. Each RAN group has a unique RAN group public identifier, and each MTC group has a unique MTC group public identifier. The RAN group public identifier has a corresponding relationship with the MTC group public identifier, and the corresponding relationship may be one-to-one, many-to-one, one-to-many or ma...

Abstract

The invention discloses a machine type communication common message transmission method, which is used for saving network resources and improving system capacity and efficiency. The method comprises that: a network side determines a radio access network (RAN) group corresponding to a machine type communication (MTC) group required to receive a paging message, and acquires a radio network temporary identifier (RNTI) of the RAN group; the network side generates the paging message; and the network side transmits the RNTI and the paging message to MTC terminals in the determined MTC group in a multicast way. The invention also discloses a device for implementing the method.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a device for transmitting machine-type communication public messages. Background technique [0002] For some industries with a relatively large number of terminals, such as water meters, electricity meters, and gas meters, etc., the human-to-human (H2H) mode is still used to transmit information, and the efficiency is very low. In order to solve the defects of H2H communication, the third generation mobile communication system and its long-term evolution system need to support the machine type communication (Machine Type Communications, MTC) function, and the machine-to-machine (M2M) communication mode is proposed. In the M2M communication mode, there is no clear solution on how to send the same information to multiple MTC users. [0003] The methods for sending information to multiple users in the prior art include broadcast, multicast and paging. System broadcast is use...
