Embodiment 1

[0094] This embodiment introduces the method for the cluster system to receive short messages, specifically as figure 2 shown, including:

[0095] Step 101, the base station subsystem (BSS) receives the short message sent by the cluster terminal, and sends the short message sent by the cluster terminal to the cluster scheduling server (PDS);

[0096] Step 102, the PDS sends the short message to the industry application server (AS);

[0097] Step 103, the AS judges the recipient type of the short message, if the recipient type is a terminal, then put the short message into the delivery waiting queue, if the recipient type is a dispatcher, then forward the short message to the dispatching proxy server ( DAS).

[0098] In a preferred embodiment, in the above process, in step 101, if the BSS receives the short message sent by the cluster terminal through the control channel, or the short message sent by the cluster terminal through the established service channel, the BSS can d...

Embodiment 2

[0105] This embodiment introduces the method for the trunking system to send a short message, that is, the process of the trunking system delivering a short message to the trunking terminal, such as image 3 shown, including:

[0106] Step 201, when the industry application server (AS) delivers a short message to the cluster terminal, it takes out the short message from the delivery waiting queue, and sends the short message to the cluster scheduling server (PDS);

[0107] Step 202, the PDS sends the short message to the base station subsystem (BSS), and indicates the channel type to be used;

[0108] Step 203, the BSS sends the short message to the receiver cluster terminal of the short message.

[0109] In a preferred embodiment, after the above step 201, after the PDS receives the short message, it can first send an authentication request to the scheduling home register (PHR), requesting the PHR to authenticate the receiver cluster terminal of the short message, and judge ...

Embodiment 3

[0123] In order to realize the method of above-mentioned embodiment 1 and embodiment 2, need to improve existing system:

[0124] The software of the base station subsystem needs to be modified: forward the short message signaling originally forwarded to the switching subsystem to the cluster scheduling subsystem, and be able to process the short message signaling sent by the cluster scheduling subsystem; Send short messages to the terminal in the channel.

[0125] In the cluster scheduling subsystem, the short message service set up on the industry application server AS is expanded so that it can flexibly work in two modes of private network and public network. If required by the business, the SMS service can be directly connected to the SMSC device to realize complex and diverse SMS requirements. In situations where the cost of networking and equipment is limited, or where the real-time requirements for short messages in trunking calls are high, you can switch to the privat...

Abstract

The invention discloses a short message transmitting and receiving methods in a cluster system and apparatuses for realizing short message transmitting and receiving by a terminal, so that the short message service of the cluster system can be realized without depending on an exchange sub system. The short message receiving method comprises the following steps that: a base station subsystem (BSS) receives a short message sent by a cluster terminal and the short message sent by the cluster terminal is sent to a PTT dispatch server (PDS); the PDS sends the short message to an application server (AS); the AS determines a receiving party type of the short message; if the receiving party type is a terminal, the short message is put into a delivery waiting queue; and if the receiving party type is a dispatching platform, the short message is forwarded to a dispatch agent server (DAS). The short message sending method comprises the following steps that: an AS takes a short message out of a delivery waiting queue and sends the short message to the PDS; the PDS sends the short message to the BSS and indicates a using channel type; and the BSS sends the short message to a receiving party cluster terminal of the short message. According to the application, an exchange sub system is not needed; and equipment reduction is realized and the service integrity is also ensured.

Description

technical field [0001] The invention relates to the field of digital trunking communication, in particular to a method for sending and receiving short messages in a trunking system and a device for realizing the sending and receiving of short messages by trunking terminals. Background technique [0002] The trunking communication system is an important branch of the mobile communication system. The early dedicated mobile communication was mainly done by point-to-point half-duplex radio walkie-talkie, which was limited to the field of professional mobile communication. In addition to the call function, the modern trunking communication system also supports many functions such as text messages, data services, positioning, and video. , the two are getting closer. [0003] The users in the trunking system generally take the group as the unit. In order to facilitate unified scheduling, the function of the dispatching station to send notification messages to the users in the gro...
