Abstract:
PROBLEM TO BE SOLVED: To provide techniques for supporting location services with roaming.SOLUTION: A mobile station 110 communicates with a visited network 102a for a data session and receives a request for its location. The mobile station sends first information (e.g., SID and NID) indicative of its current network location to an H-MPC 160. The H-MPC 160 determines a serving mobile positioning center (S-MPC) 150 in the visited network based on the first information. The S-MPC 150 determines a serving position determining entity (S-PDE) 140 in the visited network based on the first information. The H-MPC 160 may receive an S-PDE address or a position estimate of the mobile station from the S-MPC and may forward this information to the mobile station. The mobile station 110 may communicate with the S-PDE 140 for positioning using the S-PDE address.

PROBLEM TO BE SOLVED: To provide a method for supporting location services with roaming.SOLUTION: A mobile station 110 communicates with a visited network 102a, receives a request for the mobile station's location, and sends first information (SID and NID) indicative of its current network location to a home mobile positioning center (H-MPC) 160 in a home network 104a. The H-MPC 160 determines a serving mobile positioning center (S-MPC) 150 in the visited network 102a based on the first information. The S-MPC 150 determines a serving position determining entity (S-PDE) 140 in the visited network based on the first information. The H-MPC 160 receives an S-PDE address or a position estimate of the mobile station from the S-MPC 150 and forwards this information to the mobile station 110. The mobile station 110 communicates with the S-PDE 140 for positioning using the S-PDE address.

Abstract:
Methods and apparatuses are provided for facilitating authentication of access terminal identities and for recording a usage relationship between a valid access terminal identity and a user identity. An access terminal and a validation server are both provisioned with corresponding validation keys. The access terminal may determine that a user identity is not recorded for use with the access terminal, and may send a report message to report a usage relationship between the access terminal identity and the user identity, where the report message is signed with a signature based on the validation key. The validation server authenticates the signature using the validation key in the validation server. The validation server may record the usage relationship between the authenticated access terminal identity and the user identity in a database, which database records may be employed to determine whether an access terminal requesting network access is authorized or unauthorized.
Abstract:
Methods, systems, and devices are described for wireless communication. A wireless device such as an in-vehicle system (IVS) may transmit an emergency call (eCall) message to a third party eCall server using a communication session which may be packet based or circuit based. The eCall message may include session information and telematics data. The third party eCall server may relay the session information and telematics data to a public safety answering point (PSAP). For example, the third party eCall server may generate an automatic text-to-speech message that is transmitted to the PSAP over a public communications network. In some cases, the third party eCall server may transmit a response to the wireless device including metadata based on the telematics data transmitted in the eCall message. The eCall message may also include a call-back number, and the PSAP may contact the wireless device directly using the call-back number.
