  • Reject mobile-terminating SMS due to mobile not reachable flag
    Patent number: 8295815
    Abstract: The present invention provides a technique to reduce the quantity of paging attempts to mobile terminals. The technique involves periodically rejecting mobile terminating SMS (MT-SMS) messages destined to a mobile subscriber who has already had no paging response success for a previous MT-SMS message until the mobile terminal is reachable or upon the timeout of a Mobile Not Reachable Flag (MNRF) rejection period. The present invention targets mobile subscribers who were out of radio coverage and allows the mobile subscriber to terminate voice calls. Mobile terminal originated activity is not affected. The present invention may co-exist with the existing SMS Center mobile terminating SMS polling mechanism in the market today.
