1. A method of associating a user service with a Mobile Station ISDN Number (MSISDN), the user service accessible by a telephony device via an application on the telephony device, the telephony device configured to communicate in a radio telephony network (RTN) and identifiable via the MSISDN when operating in the RTN, the method comprising:
sending, by an application server providing the user service, a token usable to uniquely identify the application on the telephony device, wherein the user service is remotely provided to the telephony device;
receiving, by the application server from the application on the telephony device via an RTN-native service over the RTN, the token that was previously sent to the application by the application server;
receiving, from a network node in the RTN, the MSISDN of the telephony device, the MSISDN determined based on control signaling associated with the RTN-native service when the token is being sent from the telephony device to the application server over the RTN; and
based on the application server determining that the token received from the telephony device via the RTN-native service matches the token that was sent by the application server to the telephony device, associating the received MSISDN with the user service to enable the user service to provide services to the telephony device based on the MSISDN, wherein the application on the telephony device does not have permission to directly access the MSISDN and provide the MSISDN to the application server, and wherein the control signaling associated with the RTN-native service enables the MSISDN to be determined and provided to the application server by the network node in the RTN without directly receiving the MSISDN from the telephony device.
