Embodiment Construction

[0069] In the following, the method of the present invention will be described in detail for the situations of group call establishment and group call establishment respectively.

[0070] see figure 2 , is the flow chart of the successful sending of the short message when the group call of the present invention is established. After the SC receives the group sending short message from the sender, the short message is stored locally, and the following steps are performed:

[0071] Step 1, SC sends a short message with group call reference to SMS-GMSC;

[0072] Step 2, SMS-GMSC queries the external database or HLR according to the group call reference carried by the short message, finds the A-MSC address of this VGCS service; sends the short message with the group call reference to the corresponding A-MSC;

[0073] Step 3, A-MSC queries the current attributes and dispatcher list of this group call in the corresponding GCR;

[0074] Step 4, GCR returns to A-MSC the group call ...

Abstract

The method is used in trunking communication system and comprises: saving the short message in system; if the group calling is established, then the short message is transmitted according to the routine; after a successful sending, deleting the saved short message; if the sending failures, the short message is retransmitted according to the routine; if the transmission succeeded, deleting the saved short message; if transmission failures, the short message is retransmitted to the group user using point-to-point transmission way.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for realizing group sending of short messages in the short message service of a trunking wireless communication system. 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 f...
