    Abstract: PROBLEM TO BE SOLVED: To provide a messaging protocol to start a positioning function, independently of the current call processing state of a mobile object. SOLUTION: When a mobile object is in a mobile object idle state, in a system access state or in a traffic channel state, a serving base station or the mobile object transmits a positioning request. A messaging protocol describes how a positioning function is started, when the mobile object is resident in any of various call processing states and used to identify a messaging required between a serving base station and the mobile object. Then the mobile object transmits a positioning trial message to the base station. The positioning trial message is formatted according to positioning parameter data and includes at least one positioning probe with a mobile object identification number or a probe number. The base station discriminates the position of the mobile object on the basis of the positioning trial.

    Abstract: The messaging protocol modifies current CDMA systems to initiate a position location function while providing minimal interference to the system and preserving battery life. There are circumstances when a mobile position location may need to be performed when the mobile 40 is in a mobile idle state, a system access state or a traffic channel state. These location requests can come from a serving base station or from the mobile. In addition, for certain location services, the position of the mobile may have to be located periodically. The messaging protocol describes how the position location function is to be initiated when the mobile is in various call processing states and identifies the messaging needed between the serving base station and the mobile. The serving base station transmits a location order message that includes location parameter data to the mobile. The mobile then transmits a location attempt message to the base station. The location attempt message is formatted according to the location parameter data and includes at least one location probe having the mobile identification number or a probe number. The CDMA system then determines the position of the mobile based on the location attempt.
