Global calling terminal missed call cuing method based on virtual terminal

Abstract

The invention discloses a virtual terminal-based global calling terminal missed call prompting method. A virtual terminal for missed call prompting is set in a code division multiple access CDMA network or an intelligent network, and the legal user data of the virtual terminal is stored in the home In the home register HLR, the virtual terminal is always in an unreachable state. and corresponding information to notify missed users; the present invention has the advantages of business integrity, no damage, dual economy and globalization of service objects.

Description

technical field [0001] The invention relates to a call transfer method for mobile communication, in particular to a virtual terminal-based method for providing call terminals worldwide with a missed call prompt service. Background technique [0002] With the increasing maturity of communication technology and the increasing saturation of communication users, how to further increase the Average Revenue Per User value of users through business innovation, abbreviated as ARPU, so as to achieve the purpose of making the entire industry chain profitable and gradually become a communication operator and even the focus of the entire industry. [0003] In daily life, users are usually unable to connect due to various factors such as the mobile phone is turned off, there is no network coverage, the phone is in the middle of a call, or the owner of the landline is not at home, thus losing a lot of important information, and for operators, a lot of loss Earnings from calls. Call forw...

Problems solved by technology

However, the various existing solutions have corresponding disadvantages: 1. The secretary platform is a high-end application, which to some extent raises the threshold for using the business, resulting in only a small number of users being able to enjoy such services, and Ruyihuo Or a global call will cause the calling user to generate communication fees

2. Using the MAP and A interface monitoring methods of the mobile application to realize the missed call service will have the following main problems: (1) The monitoring of the A interface will lead to a lot of links to be monitored, and the investment is huge. The distribution area of ​​the room is wide, and there are many front-end signaling collectors that need to be placed, which is very inconvenient to implement and maintain; (2) Since the base station controller BSC and the switching network need to be continuously adjusted according to network optimization, it will lead to huge business maintenance costs in the future; (3) It will be difficult to properly solve the technical problems of IMSI or TMSI conversion; (4) Roaming cannot be supported

3. The forwarding solution needs to add a new voice device in the network as a receiving terminal for missed calls. The main problems are: (1) This voice device will occupy the point code resources and relay resources of the network, which not only requires a lot of investment large, and each unsuccessful call occupies too much network channel resources; (2) when there are many missed calls at the same time, it is possible that the missing call detection may be lost due to insufficient relay resources; (3) based on The switch forwarding solution cannot solve the problem of missed call prompts in the case of user roaming, which damages the integrity of the solution

4. Monitoring the attribution register HLR of the code division multiple access CDMA switch to obtain the missed call information can only provide the missed call information to the shutdown user, and cannot obtain the missed call information generated by users in other states

These are the Achilles' heels of the commonly used code division multiple access CDMA missed call prompt information
