Abstract
An emergency location server may receive push location messages from a handset as the handset initiates a call to a public safety answering point (PSAP). The PSAP may request the location information from the location server by identifying the MSISDN of the handset. If the push message does not contain an MSISDN, the location server may send a message, e.g. SRI-SM message, to the home network of the handset to retrieve the MSISDN and associate the MSISDN with the location information in the push location message. This enables the location server to provide location responses to the PSAP even when the handset is unaware of its MSISDN.
