Claim:
1. A method performed by an Over The Top (OTT) service providing node for retrieval of geographic location information of a communication device, the communication device being communicatively coupled to the OTT service providing node via a communication network, in which an Operator Location Service (OLS) node is separately employed to retrieve the geographic location information of the communication device, instead of the OTT service providing node, the method comprising: receiving a request for an OTT service from the communication device; determining a global identifier of the communication device; determining an operator of the communication device by utilising the determined global identifier of the communication device to access a Domain Name Server (DNS) or an Internet Registry to obtain an identifier of the operator; determining an identifier of the OLS node of the operator by utilising the identifier of the operator to access the DNS or the Internet Registry to obtain the identifier of the OLS node; sending a location request to the OLS node, by using the identifier of the OLS node, for requesting geographic location information of the communication device, the location request comprising the global identifier of the communication device, wherein the global identifier of the communication device is to be utilised by the OLS node to determine a host identifier (Host-ID) of the communication device to access a location server (LCS) of the operator based on the Host-ID, instead of the OTT service providing node accessing the LCS, for retrieving the requested geographic location information from the LCS to the OLS node, and the retrieved geographic location information to be sent by the OLS node to the OTT service providing node; and receiving the sent geographic location information from the OLS node.
