Research And Implementation Of The Voice User Plane System In The Coal Private Network Based On The TD

With the information technology of coal production and the mature development ofTD-SCDMA technology,a new type of wireless communication technology more and moreserved colliery communications,development and construction of colliery wirelesscommunication system has become urgent need for coal production and the safety ofprotecting the production staff. To this end, the state-of-the-art TD-SCDMA technology usedin colliery communication system,establishing a set of mine communication system that issuitable safe production and management of coal enterprises is imperative. In the network ofthe coal industry application environment, how successfully design the voice user planesystem to provide users with high-quality voice services is an important issue worthy of study.For coal enterprises demand to voice services, a new enterprise network design scheme basedon TD-SCDMA technology of wireless communication system is proposed,systemcomposition and function characteristics and network element are described, a nd a number ofkey technologies of voice services implemented are analyzed. On this basis, overall designscheme of core network CS domain is proposed, and voice signaling processes is designed,and the voice user plane system is emphatically designed and implemented. In the course ofthe study,from the perspective of protocol stack structure and module division special networkuser plane is designed,and the signaling processing sub-module and data processingsub-module handling processes and software implementation process is completed.Eventually a hardware and software test environment successfully is built,the applicationsoftware migration is completed,and voice service system from the signaling and user planetwo aspects is comprehensively tested.The results show that the new type of TD-SCDMA network communication systemintegrated access network and the core network, implement effectively voice communicationfunction of the communication system, which is able to provide a reliable communication security for coal production and the lives of the workers.
