1. A method of acquiring location information of a user equipment (UE) for emergency services, the method comprising:
- by a first server in a communication network;
receiving a first request message from a call session server, wherein the first request message is in response to an emergency request message from the UE;
sending a Session Initiation Protocol (SIP) INVITE request message received from a call session control function to a location server, wherein the SIP INVITE request message is configured to cause the location sever to send a request for routing information to a pre-configured Gateway Mobile Location Centre (GMLC) in the communication network, wherein the request for routing information includes a current location of the UE, a public identity of the UE, and required QoS parameters established by the network operator for emergency services;
causing initiation of a Mobile Terminating Location Request (MT-LR) procedure by the GMLC upon receipt of the location request to obtain the UE'"'"'s location.

7. A non-transitory computer-readable memory medium comprising software instructions executable by a processor of a first server in a communication network to cause the first server to:
-
receive a first request message from a call session server, wherein the first request message is in response to an emergency request message from a user equipment (UE); send a Session Initiation Protocol (SIP) INVITE request message received from a call session control function to a location server, wherein the SIP INVITE request message is configured to cause the location sever to send a request for routing information to a pre-configured Gateway Mobile Location Centre (GMLC) in the communication network, wherein the request for routing information includes a current location of the UE, a public identity of the UE, and required QoS parameters established by the network operator for emergency services; cause initiation of a Mobile Terminating Location Request (MT-LR) procedure by the GMLC upon receipt of the location request to obtain the UE'"'"'s location. - View Dependent Claims (8, 9, 10, 11, 12)
