Abstract:
1. A method for use in a cell phone network comprising: a. A Short Message Service Center (SMSC) receiving a text message or Short Message Service (SMS) for delivery to a mobile station (MS); b. The SMSC querying the Home Location Register (HLR) of the MS for routing information; c. The SMSC receiving the routing information for the MS for SMS Mobile Terminated Operation; d. The SMSC sending the SMS to the Mobile Serving Switch (MSC) using the ForwardShortMessage operation (FSM); e. The MSC retrieving the subscriber information from the Visitor Location Register, (VLR); f. The MSC sending the Location Services, (LCS), query requesting the InterSystemPOSitionREQuest, (ISPOSREQ), and, including in the query a request for Position Quality of Service information, (PQOS); specifically, the ISPOSREQ query will include parameters requesting the PQOS parameter of Horizontal Velocity measurement be returned in the response to the ISPOSREQ query; g. The MS including the PQOS' Horizontal Velocity measurement in its response to the Location Services' ISPOSREQ query; h. The MSC receiving the PQOS parameters from the MS that includes Generalized Time, Geographic Position, Position Source, Horizontal Velocity and Vertical Velocity; i. The MSC comparing the received Horizontal Velocity to a predetermined maximum value for velocity; j. The MSC initiating “SMS Mobile Terminated Delivery Unsuccessful” procedures when the Horizontal Velocity returned to the MSC from the MS in its response to the ISPOSREQ query exceeds the predetermined value; and, k. The MSC allowing SMS Mobile Terminated (SMS-MT) delivery to be processed when the Horizontal Velocity returned to the MSC from the MS in its response to the ISPOSREQ query does not exceed the predetermined value.
