Method and system for receiving and dispatching short message in cluster communication system

Abstract

The invention discloses a method of sending and receiving short messages in a trunking communication system, wherein, a short message center module receives short messages sent by end users and sends short message delivering orders to a trunking short message service module according to group short message accessing signals in short messages; a trunking short message service module receives and analyzes short message delivering orders, and then sends short message delivering request signals to a short message entity and sends short message delivering responses back to a short message center module; a short message entity receives and analyzes the short message delivering request signals and sends information requests to a dispatching assignment register; and the short message entity sends short message notification short messages to a client according to information request responses sent back. Meanwhile, the invention also discloses a system of sending and receiving short messages in a trunking communication system which comprises a short message center module, a group short message service module, a short message entity, a dispatching assignment register and a client. The invention overcomes the technical shortage that end users can not send short messages to dispatching agent clients under the prior art.

Description

Technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and system for sending and receiving short messages in a cluster communication system. Background technique [0002] The trunking communication system is an important branch of the mobile communication system. The early dedicated mobile communication was mainly completed by radio walkie-talkies for point-to-point half-duplex communication, limited to the field of professional mobile communication; as the field of wireless communication develops in the direction of digital communication technology , The trunking communication system has also begun to develop to the second generation of digital technology, the most important feature is the use of time division multiple access (TDMA, Time Division Multiple Access) technology. [0003] In order to promote the large-scale application of the trunking system and to further increase the frequency utilization rate, a new ap...

AI Technical Summary

Problems solved by technology

Through the method and system, it is possible to overcome the technical defect that in the existing digital trunking system, the short message can only be sent by the dispatching agent client to the end user, but the end user cannot send a short message to the dispatching agent client, and the short message of the trunking communication system is supplemented. function, and meet the purpose of the user's use of the digital trunking system
