Abstract

The invention provides a method for issuing assisted locating data by broadcasting, and a secure user plane location platform (SLP) obtains assisted locating data relevant to a position area; the SLP obtains broadcasting location area information of the assisted locating data; and the SLP distributes the assisted locating data and the broadcasting location area information to a broadcast functional entity and requests the broadcast functional entity to distribute the data and information by broadcasting. The utility model also discloses a system for issuing assisted locating data by broadcasting, through the method, the transmission of the assisted locating data can be realized, in addition, the assisted locating data is issued aiming at certain area coverage, and users within the area coverage can receive the assisted locating data by broadcasting, so that large load to a network can be avoided, and simultaneously the locating accuracy is improved.

Description

technical field [0001] The invention relates to secure user plane positioning (SUPL) technology, in particular to a method and system for broadcasting and sending auxiliary positioning data. Background technique [0002] As one of the characteristic services of the mobile communication system, the positioning service has been considered to be a bright spot of the future mobile value-added services. At present, major mobile communication operators in countries and regions such as North America, Europe, Asia Pacific, Japan and South Korea have launched mobile positioning services. The positioning service is the most attractive service in the mobile value-added service, and it is also one of the most complicated services in every link of the industry chain. [0003] LOC is an organization established by the Open Mobile Alliance (OMA, Open Mobile Architecture) in 2002 by merging the work of the LIF Forum, the positioning service in the WAP Forum, and the work related to 3GPP R6...
