SIM-BASED POSITIONING

In various embodiments, techniques are provided for deploying a positioning applet to a SIM (e.g., a physical SIM card or an embedded SIM (eSIM)/integrated SIM (iSIM)) via an over-the-air (OTA) update or by permanent programming (i.e. "burning in") during manufacture. The positioning applet may run solely on a processor of the SIM, functioning without support of application, OS or baseband software executing on the CPU or baseband processor of the UE, or network deployed infrastructure support. In operation, the positioning applet collects positioning measurements from a baseband processor (e.g., a baseband chipset) of the UE (e.g., via 3GPP protocols) which are sent (e.g., as an encrypted payload) to a remote location platform that compares the positioning measurements to known positioning data in a database (e.g., a crowd sourced database) to determine UE position. The remote location platform may provide an estimated position to a designated recipient system, without involvement of the UE.
