Embodiment Construction

[0052] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0053] refer to figure 2 The system structure diagram shown describes the upgraded gpsOne positioning platform to support control plane positioning, and other network elements irrelevant to the present invention are omitted in the figure. The system structure diagram mainly includes: LCS CLIENT (location service client), MS, MPC connected to the packet data network, PDE, WARN (WARN-WideArea Reference Network, wide area reference network), HLR (home location register), MSC, PDSN (packet data service node). Among them, the positioning system includes MPC, PDE, and WARN; HLR, MSC, and PDSN belong to the CDMA 1X network; LCS CLIENT is a client responsible for sending positioning requests and receiving positioning results of...

Abstract

The invention discloses an implementation method and MPC equipment for increasing the positioning success rate, including: when the MPC receives a positioning request from the LCS CLIENT, the MPC checks the terminal capability, and if the target terminal for positioning supports high-precision positioning or has no terminal capability information, then Use the positioning method with the highest positioning accuracy supported by the mobile station; if the target terminal supports gpsOne, when the IS801 method of gpsOne fails, the MPC uses the user plane CELL ID method to return user positioning information; if the target terminal does not support high-precision positioning, high When the precision positioning fails, the MPC re-initiates the control plane positioning and returns the user positioning service. The present invention can realize the addition of a positioning fallback mechanism in the original standard positioning service process, and achieve the improvement of the non-high-precision positioning success rate and the user's service use perception degree at a relatively small cost, and is beneficial to the operator to promote the service based on the location service.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for realizing increasing the positioning success rate and mobile positioning center (MPC) equipment. Background technique [0002] Location Based Services (LBS for short), also known as mobile location services or positioning services, means that the mobile network obtains the geographic location information (latitude and longitude coordinates) of mobile terminals through specific positioning technologies, and provides them to mobile users themselves, communication System or a third party, with the support of certain electronic map information, provides mobile users with calling or non-calling services related to their location. [0003] Positioning is divided into high-precision gpsOne positioning (user plane positioning) and coarse-precision positioning (control plane positioning). At present, the services are provided by the high-precision positioning pl...
