Abstract


The phone is becoming increasingly popular today, it is undeniable phone really gives users a lot of convenience, it meets the needs of users call anywhere, but at the same time, the phone also brings the user a lot of embarrassment and inconvenience. Meetings suddenly the caller will disturb the atmosphere of the meeting; answering the phone will give drivers dangerous driving; movies answer phone will disrupt the mood to see a movie, hang up the phone directly to the caller also worried caused misunderstanding. Sometimes I think the rest do not want to be awakened; want to deal with things that do not want to be independent telephone disturb peace of mind, but there is always some unimportant phone call came. With the growing demand for calls DND on the market, there have been many scrambling Free class business. Both terminal-based implementation, based on the network side. However, calls firewall implementation based on terminal-to-end requirements higher, and a single business function; these issues makes business based on network measurements to achieve the DND service access difficulties, and can only be called default call Disturb the stagnation of development. Improvement program described in this article VAS2000 platform for the development of non-acute disturbance operations for a single function, access difficulties, can only be called default. The program draws on the existing GSM network has call forwarding supplementary services, no new requirements on the terminal and the network; way through the MAP interface directly connected HLR real-time modify the user's unconditional call forwarding settings; and rich business functions, break through the traditional default way to handle incoming only by the called function to allow the caller to choose according to the actual situation. Has a very broad market prospects. Technology principle and the VAS2000 value-added business platform call forwarding elaborated on the basis of a detailed analysis of the non-acute disturbance business design and implementation of the program. The main contents include: Call transfer technology background and basics; VAS2000 platform system functionality and performance point of view of non-acute disturbance business needs analysis; core part describes the non-acute and not disturbing the overall design of business systems and analyzes business The logical part of the detailed design and implementation methods; After test and practical application of business cases. Summed up at the end of the article of the Master during the project work, and non-acute disturbance prospects for the development of the business outlook.
