System and method for efficiently supporting broadcast support of location support data in wireless networks

摘要

Techniques for efficiently supporting location support data (AD) broadcasts in wireless networks are discussed herein in order to support the location of user equipment (UE).The location server (LS) may send some location ad that can be encrypted as an option to the base station for broadcast in cells supported by the base station.The capability information provided to LS by the UE, which indicates the level of support by the UE to receive broadcast AD and support encryption, is whether the additional ad need to be sent to the UE by point to point means And it is possible for the LS to determine which type of additional ad needs to be sent to the UE by point to point means.Ls may use the capability information received from a large number of UE to assist in the determination of the type of location assistance data to be broadcast and the use of encryption.Fig. 5 (a)
