Description

technical field [0001] The invention belongs to the field of trunking communication, in particular to a method for sending point-to-point short messages from users in a group call group to users outside the group in a trunking communication system. Background technique [0002] Trunking wireless communication system, 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 internal communication needs of each unit. [0003] In the current trunking 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 HLR (Home Location Register) and SIM (Subscriber Identity Module, S...
