Abstract

Systems and methods provide location support for assisted navigation systems, for example, with respect to assistance data specifications and protocols in systems without impacting a cellular system-specific control plane protocol. Location support for cellular systems can be introduced into only the user plane of a particular cellular system by including/introducing certain relevant information to existing parameters within the user plane. Additionally, support for new cellular systems is introduced into the user plane protocol by defining its “identification” to the protocol.
