  • Optimized SMS delivery algorithm
    Patent number: 6108325
    Abstract: A system and method for delivering short messages to idle mobile stations which conserves paging channel capacity. A normal page is first sent to all cells to locate the mobile station to which the short message is addressed. When the mobile station is located, the full short message is sent over the paging channel for the single cell in which the mobile station is located if the length of the short message is determined to be suitable for sending over the paging channel. If the short message is too long, then a traffic channel is established to the mobile station, and the message is sent over the traffic channel.
