Abstract

The invention discloses a locating service processing method aiming at a long term evolution / code division multiple access (LTE / CDMA) dual-mode terminal and a locating service processing system aiming at the LTE / CDMA dual-mode terminal. The locating service processing method includes that a location service client (LCS) respectively initiates a locating request of the LTE / CDMA dual-mode terminal to a gateway mobile location center (GMLC) and a mobile position center (MPC); based on a first locating service routing information, obtained from a home subscriber server (HSS) of a user of the LTE / CDMA dual-mode terminal, of the LTE / CDMA dual-mode terminal, the GMLC initiates an LET location process based on a control plane, when location is successful, the GMLC returns the information of a positioning result of the LTE / CDMA dual-mode terminal to the LCS; GLMC locating failure is responded, based on a second locating service routing information, obtained from a home location register (HLR) of a user of the LTE / CDMA dual-mode terminal, of the LTE / CDMA dual-mode terminal, the MPC initiates a CDMA location process based on a user plane, and when location is successful, the MPC returns the information of a locating result of the LTE / CDMA dual-mode terminal to the LCS. According to the locating service processing method aiming at the LTE / CDMA dual-mode terminal and the locating service system aiming at the LTE / CDMA dual-mode terminal, waste of location resources and signaling overheads can be avoided, the problem that the terminal frequently disconnects LET data connection is decreased, and service experience of a user is effectively improved.

Description

technical field [0001] The present invention relates to communication technology, in particular to a positioning service processing method and system for LTE / CDMA dual-mode terminals. Background technique [0002] With the development of mobile Internet applications, location-based service applications continue to emerge, and the requirements for positioning functions and capabilities provided by operator networks are getting higher and higher. The user plane positioning of Code Division Multiple Access (CodeDivisionMultipleAccess, hereinafter referred to as: CDMA) network can adopt positioning star (gpsOne) precise positioning method, and its network architecture includes mobile positioning center (MobilePositionCenter, hereinafter referred to as: MPC), positioning entity (PositionDeterminingEntity, Hereinafter referred to as: PDE) and location service client (LocationServiceClient, hereinafter referred to as: LCSClient). Among them, the main function of the MPC is to be u...
