Missed Call Reminder System Solution

Introduction
      The signaling-based missed call reminder service system can capture the user’s call record and status information in real time by signaling monitoring, then sort out the user’s failed call records according to the call status, and at the same time provide the calling and called numbers as well as the call time extracted from the failed call. By capturing the status information of called user, it can conduct such a functional service as creating a relevant short message and then sending the missed call reminder to the called user when the called user restores to be reached (power on or reset).

Solution
      The design idea of missed call reminder comes from the signaling monitoring system which is extracted and developed based on its basic data to avoid the weakness for transforming the existing network environment due to the missed call reminder service implementation, and at the same time, the system cost is reduced greatly.

      Basic system implementation principle: the system collects the real-time original signaling to filter the failed call information by decoding analysis and extract the calling- and called-number as well as call time from the failed call log. This log will be automatically saved to the missed call reminder service system that sends the created short message based on user’s choice when the mobile user is unable to be called because of shutting-off and-down.

      1. This system can send the missed call reminder message to the subscribing called user directly: China Unicom coming call secretary reminder: XXXX user call you at 12：30 on 17, August, please call back promptly.

      2. This system can send a missed call reminder notification to the unsubscribing called user directly: China Unicom coming call secretary reminder: there is a missing coming call query, please reply C (0.5 yen/time), payment by month (3 yen/month), without reminder, please reply 2, this reminder is free, please contact 10010 for details.

      The missed call system has been put into application in many places, brought a well experience for most users and been recognized deeply. At the same time, the system also help the operator make a great profit,  and improve the user perception and experience greatly while perfecting its service quality.
