Embodiment Construction

[0060] The process of group-sending short messages from the message sender to the SC is a prior art, and will not be described here. The solution of the present invention only solves the process from the SC to the user (MS).

[0061] Referring to Fig. 4, it is a schematic diagram of the implementation process of sending short messages in groups of the present invention, and the specific process includes:

[0062] Step 1: SC sends the short message to SMS-GMSC, and carries the mobile phone number (MSISDN) of the target group; Indicates that this is a short message for the group;

[0063] Step 2: After the SMS-GMSC receives the short message sent by the group, it recognizes it as a short message according to the MSISDN number prefix, and then queries the internal database (not marked in the figure) of the HLR or SMS-GMSC to obtain the corresponding A-MSC address, the A-MSC address is the current roaming address of the users in the group;

[0064] Step 3: SMS-GMSC sends the sho...

Abstract

The method is used for sending short message in trunking communication system in which the calling is not established, and comprises: anchor-mobile switch center (A-MSC) sends the received group-sending short messages to the base station controller (BSC) belonging to the calling cell under its direct control; the BSC uses the radio channel in the calling cell to send the group-sending short messages, and broadcasts the channel parameter information in the cell; user end receives the group-sending short message identical with his own subscription group in the group sending messages through the corresponding channel. By the invention, the group sending short messages can be sent out in case of not establishing the group calling.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for realizing short message sending by a cluster group. 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 identifier (ID) and a group call area, wherein the group call area is defined as a group of cells, and the combination of the group call area and the group ID is called a group call reference. These information are all fixed information stored in the Home Location Register (HLR) and ...
