Abstract

The invention discloses a voice over internet protocol (VOIP) voice access method applicable to a frequency division multiple access / demand assigned multiple access (FDMA / DAMA) satellite communication system and relates to voice access technology in the field of satellite communication. The method comprises accessing voice service borne by internet protocols (IP) in the FDMA / DAMA satellite communication system through procedures of intercepting and capturing data packages, asking for communication resources, allocating communication resources, conducting both-way voice communication, asking for release of communication resources, releasing the communication resources and the like. The voice access method has the advantages of automatically accessing IP voice, enabling an access flow to be completely transparent to a voice gateway and being strong in voice gateway compatible capability, and is particularly suitable to use of FDMA / DAMA satellite communication stations which use the VOIP voice gateway to conduct voice access.

Description

technical field [0001] The invention relates to a VOIP voice access control method suitable for FDMA / DAMA (Frequency Division Multiple Access / Assignment on Demand) satellite communication systems in the field of satellite communication, and is particularly suitable for satellite communication stations using VOIP voice gateways for voice access . Background technique [0002] Satellite communication has the advantages of wide coverage, strong broadcasting capability, and less restricted by geographical conditions. As the supplement and backup of the terrestrial network, the satellite network has received more and more attention at home and abroad. [0003] FDMA / DAMA (Frequency Division Multiple Access / Demand Assignment) is a commonly used satellite communication system. In the FDMA / DAMA satellite communication network, the satellite transponder frequency resources are shared by all satellite ground stations in the network, and the frequency channel is temporarily allocated ...
