Abstract
A system is provided to allow a network to obtain the location of a mobile station (e.g. mobile phone) having AGPS/AFLT CDMA capability during an emergency call—without the use of the MPCAP parameter. The MPC invokes the PDE, which is IS-801 AGPS capable, without the MPCAP parameter. The PDE then queries the mobile for its geolocation capabilities, in the absence of the MPCAP parameter. This allows a visited network (e.g. the network in which the mobile station is roaming) to obtain a position (based on IS-801 AGPS/AFLT) for roaming mobile stations that are CDMA AGPS/AFLT capable—without the use of the network MPCAP parameter.
