A data request is generated (e.g., text, email, SMS, multimedia messaging system (MMS), etc.) from a source device. The data request is delivered to a PSAP or other emergency monitoring service location in a useable format. Exemplary useable formats include a canned voice message, delivery to a call center that translates data to voice, text to speech, and text to instant messaging (IM). Additional information and location are staged for use by the PSAP or other monitoring service location.

LBS support to CDMA mobiles while roaming on another network. IS-801 session data is routed by a routing gateway to a correct visited network PDE that contains correct BSA data, which is used to return assistance data to an interrogating mobile device. A standalone exemplary roaming LBS routing gateway (XRG) provides network connectivity between PDE equipment in multiple carrier networks. Conventional LBS roaming support is defined via the use of Mobile Position Centers (MPCs). The invention implements a roaming LBS gateway to enable roaming between CDMA carriers that are only using a PDE (Positioning Determining Entity) for this purpose, since a mobile position center (MPC) is typically an optional network node according to location based services (LBS) specifications.
