Problems solved by technology

Limited by chip and equipment manufacturers' support for fax functions, only GSM and CDMA2000 networks currently provide formal commercial wireless fax services, and in actual use, there are low success rates, insufficient coverage, limited by geographical conditions, and no voice support. Alternate with fax etc.
[0004] Most of the existing technologies are only introductions to related technologies of facsimile services in terrestrial cellular mobile communication systems, and there are almost no descriptions on related technologies of facsimile services in satellite mobile communication systems

Embodiment 1

[0029] Embodiment 1: as figure 1 As shown, a facsimile system based on satellite mobile communication mainly includes a first facsimile machine 1, a satellite mobile terminal 2, a mobile communication satellite, a gateway subsystem 4, a core network 5, a relay media gateway 6, a PSTN 7 and a second Two facsimile machines 8, the first facsimile machine 1 has a plurality of them, and respectively corresponding to the same number of satellite mobile terminals 2 and connected by cables, the satellite mobile terminals 2 are all provided with a fax adapter 21, and the satellite mobile terminals 2 communicate with each other through the fax adapter 21 The first facsimile machine 1 performs the interaction of control signaling, facsimile service data packets, and voice service data packets. The facsimile adapter 21 and the first facsimile machine 1 follow the ITU-T T.30 communication protocol. The satellite mobile terminal 2 and the gateway station The subsystems 4 are wirelessly connec...

Embodiment 2

[0030] Embodiment 2: Utilize a kind of facsimile system based on satellite mobile communication that embodiment 1 provides, carry out data facsimile between two first facsimile machines 1, specifically comprise the following steps:

[0031] Step 1: The first fax machine 1Fax1 goes off-hook and dials;

[0032] Step 2: After the fax adapter 21Fa1 receives the dial, it sends a dial command to the satellite mobile terminal 2A, and the satellite mobile terminal 2A initiates a voice call to the satellite mobile terminal 2B through the satellite mobile communication network;

[0033] Step 3: After receiving the voice call, the satellite mobile terminal 2B sends a ringing signal to the called first fax machine 1Fax2, Fax2 picks up the answer, and the fax adapter 21Fa2 sends an answer command to the satellite mobile terminal 2B, and the satellite mobile terminal 2B moves to the satellite The communication network initiates a voice response, and at this time, a normal voice call can be ...

Embodiment 3

[0044] Embodiment 3: Using the facsimile system based on satellite mobile communication provided in embodiment 1, data facsimile is performed between the first facsimile machine 1 and the second facsimile machine 8, specifically including the following steps:

[0045] Step 1: The first fax machine 1Fax1 goes off-hook and dials;

[0046] Step 2: After the fax adapter Fa1 receives the dial, it sends a dial command to the satellite mobile terminal 2A, and the satellite mobile terminal 2A initiates a voice call to the second fax machine 8Fax3 through the satellite mobile communication network and PSTN;

[0047] Step 3: The called second facsimile machine 8Fax3 picks up the phone to answer, and initiates a voice response to the satellite mobile communication network through the PSTN. At this time, the first facsimile machine 1Fax1 and the second facsimile machine 8Fax3 can conduct normal voice calls;

[0048] Step 4: Press the "Fax Start" button of the first fax machine Fax1 to sen...

Abstract

The invention discloses a fax system and method based on satellite mobile communication. The fax system comprises a first fax machine, a satellite mobile terminal, a mobile communication satellite, agateway station subsystem, a core network, a relay media gateway, a public switched telephone network (PSTN) and a second fax machine. The faxing method comprises the following steps: a data fax method between two first fax machines and a data fax method between the first fax machines and a second fax machine. By using the fax method, the fax service application problem based on a satellite mobilecommunication network can be solved, the fax service interconnection and intercommunication problem of the satellite mobile communication network and a traditional PSTN network is solved, and alternate transmission of voice services and fax services is achieved. In conclusion, the system has the advantages of being complete, high in intelligent degree, convenient to use and the like.

Description

technical field [0001] The invention belongs to the technical field of satellite communication, in particular to a facsimile system and method based on satellite mobile communication. Background technique [0002] Wireless fax is an important extension and supplement of traditional PSTN wired fax. It provides users with a more convenient and fast fax method. It is widely used in government agencies, military, armed police, public security, forestry, animal husbandry and fishery, and mobile business. And it is used as an effective solution for fax service coverage in mountainous areas, lakes, offshore and remote areas. [0003] The existing wireless fax service utilizes the data transmission capability of the circuit domain of the mobile communication network to realize the bearing of G3 fax and the intercommunication with PSTN network G3 fax. Limited by chip and equipment manufacturers' support for fax functions, only GSM and CDMA2000 networks currently provide formal comme...
