Embodiment Construction

[0049]The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0050] The present invention can be used in the situation that members in the group send trunk group short messages, members in the group can know whether the current group call is established through NCH, if the group call has been established, the user directly sends a short message, which conforms to the existing technology that the group call has been established In the case of a group call; if the group call is not established, the user terminal automatically sends a group call establishment request before sending a short message, and the user sends a short message after the group call is established.

[0051] Such as Figure 4 Shown, is the schematic flow chart of the present invention group sending short message, as seen from the figure, the present invention mainly comprises the following steps:

[0052] S1, send the short message...

Abstract

The method thereof comprises: a) the user of sending short message decides if the call of his group is established; if yes, then entering step b; if not, then entering step c; b) the user of sending short message sends the short message on the established channel; c) the user of sending short message initiates request for establishing group call, establishes the group call, and returns to step b. The system thereof comprises a short message center, a short message gateway, a mobile switch center and a mobile station. The mobile station decides if the call is established by reading the message from NCH (notification channel).

Description

technical field [0001] The invention relates to the field of communication, in particular to a method and a system for sending short messages by cluster groups. Background technique [0002] Trunking wireless communication system, hereinafter referred to as trunking system, is a relatively economical and flexible command and dispatch communication system developed in recent years, widely used in government agencies, energy transportation, airport terminals, industrial and mining enterprises, fire police, water conservancy and Military and other units to meet the needs of internal communication of each unit. [0003] In the current trunking communication system, each group includes a group identification ID and a group call area, wherein the group call area is defined as a group of cells. However, these information are all fixed information stored in the Home Location Register (HLR) and the SIM card when the account is opened, and the mobility management of the group call us...
