Description

Global call terminal missed call prompting method based on virtual terminal

Technical field

The present invention relates to a call forwarding method for mobile communications, and more particularly to a method for providing a missed call alert service for a global range of calling terminals based on a virtual terminal.

Background technique

With the increasing maturity of communication technologies and the increasing saturation of communication users, how to further increase the average revenue per user of the user through the business innovation, the Average Revenue Per User value, abbreviated as ARPU, so that the purpose of making the entire industry chain profitable becomes a communication operator. And even the focus of the entire industry.

In daily life, users often lose access to important information because of mobile phone shutdown, no network coverage, ongoing calls, or the landline owner is not at home, which loses a lot of important information and loses a lot for operators. The revenue of the call. The call forwarding missed message is to provide the main and called users with value-added services for missed calls in this way, thereby improving the quality of the service and facilitating the user, and at the same time, recovering the originally lost call revenue for the operator.

At present, various corresponding prompting methods are: secretarial desk service, wishful call or global call implementation, signaling monitoring implementation, business office user batch forwarding mode and switch forwarding. However, the existing various schemes have corresponding shortcomings: 1. The secretarial desk belongs to high-end applications, which improves the usage threshold of the service to a certain extent, resulting in only a small number of users being able to enjoy such services, and wishing to call Or the global call will cause the calling user to generate communication fees. 2. The following major problems exist in the implementation of the MAP and A interface monitoring methods of the mobile application: (1) The monitoring of the A interface will result in a large number of links to be monitored, and the investment is huge. The switch room has a wide distribution, and there are many front-end signal acquisition machines to be placed. It is very inconvenient to implement and maintain. (2) Since the base station controller BSC and switching network need to be adjusted according to network optimization, the service maintenance cost is huge in the future. (3) The technical problem of the International Mobile Station Identifier (IMSI) or Temporary Mobile Station Identifier TMSI conversion will be difficult to resolve properly; (4) Roaming cannot be supported. 3. The forwarding plan needs to add a new voice device to the network as a receiving terminal for missed calls. The main problems are: (1) The voice device needs to occupy the network's point code resources and relay resources, not only the investment Large, and each unsuccessful call occupies too much network voice resources; (2) When there are a large number of missed calls at the same time, there may be loss of missed call detection due to insufficient relay resources; (3) Based on The switch forwarding solution cannot solve the missed call prompt problem in the case of user roaming, which impairs the integrity of the solution. 4. The HLR of the monitoring code division multiple access CDMA switch's home register HLR can only provide the missed call information to the shutdown user, and the missed call information generated by the other users cannot be obtained. These are the Achilles heel of the commonly used code division multiple access CDMA missed call information.

Summary of the invention

The invention provides a virtual terminal-based global call terminal missed call prompting method, which is to use a calling terminal in a global scope as a service object, and obtain a calling terminal through a code division multiple access CDMA network or an intelligent network-specific technical system. The missed message, and timely telling the missed user in the manner of missed user selection, can solve the technical problem of the international mobile station identifier IMSI or the temporary mobile station identifier TMSI conversion; the method supports roaming, and can realize user leakage at any time. The prompting, and the set virtual terminal resources are sufficient, will not cause the loss of missed call detection; each unsuccessful call will not occupy the network channel resources; the method also solves the user in any state (including for all calls, not Service area, shutdown, no answer, busy, unreachable, etc. After setting call forwarding, you can get missed messages and can not generate communication charges for callers and missed users.

The technical solution of the present invention is as follows:

A virtual terminal-based global call terminal missed call prompting method, characterized in that: a virtual terminal for a missed call prompt is set in a code division multiple access CDMA network or an intelligent network, and legal user data of the virtual terminal is registered at the In the home register HLR, the virtual terminal is always in an unreachable state.

When the virtual terminal is set in the code division multiple access CDMA network, after the missed call user sets the call transfer to the virtual terminal, when the virtual terminal is in the called state, the mobile switch first queries the virtual terminal to the home register HLR to which the virtual terminal belongs. The status and location request request LocationRequest process, and assign the temporary local phone number TLDN as the voice route number; through the location request location request process request message, the location request locationRequest process request message carries the corresponding caller number of the call, The missed subscriber number and the virtual terminal number are then notified to the missed subscriber of the calling number, the missed subscriber number and the corresponding information according to the receiving mode specified by the missed subscriber, including the short message, website, information desk, mailbox, and telephone call.

When the virtual terminal is set in the intelligent network, after the missed call user sets the call transfer to the virtual terminal, when the virtual terminal is in the called state, the home address register HLR to which the virtual terminal belongs returns the subscription information, the mobile switching office MSC or the service exchange. The point SSP gets the called party in the data terminated by the CAMEL subscription information. Transmitting the address of the control point SCP, and then sending an initial detection point IDP message to the exchange control point SCP, the calling number, the missed call number and the virtual terminal number are included in the initial detection point IDP message, and then included by the user specified by the missed call The receiving mode such as SMS, website, information desk, email, and telephone call will notify the missed user of the calling number, the missed subscriber number and the corresponding information.
