    Abstract: Establish and maintain an IMS emergency call when a UE moves (roams) to a visited network. Receiving at a first network entity (Location and Routing Function, LRF) a request for location of a user equipment, UE, from a second network entity (emergency call session control function, E-CSCF); determining the location of the UE (by seding a retrieve location message from the E-CSCF to the LRF); assigning a temporary identity (i.e. an Emergency Service Query Key, ESQK, or Emergency Service Routing Key, ESRK) for the UE; sending the temporary identity (i.e. ESQK or ESRK) and the location of the UE to the second network entity (E-CSCF); receiving a verified information for the UE from the second network entity (i.e. receiving a SIP re-invite or SIP update message); and associating the verified information with the temporary identity (i.e. ESQK or ESRK) for the UE.

    Abstract: Techniques to support positioning of roaming mobile stations are described. A roaming mobile station communicates with a visited network and has a data connection to a home network. The mobile station sends a request for positioning assistance to a home position determining entity (H-PDE) in the home network. The H-PDE determines that base station almanac (BSA) data applicable for the mobile station is not locally available and sends a request for location information for the mobile station to a designated network entity. This entity may be a BSA server storing BSA data for different networks or a visited PDE (V-PDE) in the visited network. The H-PDE receives location information (e.g., BSA data, assistance data, and/or a position estimate for the mobile station) from the designated network entity and provides positioning assistance to the mobile station based on the received location information.
