  • Location tagging method for packet based signalling
    Patent number: 9246954
    Abstract: Location information is tagged in a packet based network. SIP signaling messages are used to initiate a communication session between at least two end user devices in a packet based telecommunications network. The communication session is routed through various intermediate network elements of the packet based network. The intermediate network elements tag the signaling messages with information indicating their geographic location or otherwise provide such location information. In response to the signaling messages and preferably before the communication session is established, the location information indicating the location of the intermediate network elements in the routing of the communication session between the end user devices is made available. An end user device or apparatus may receive the location information and provide a user display indicating the routing and status of the communication session being initiated.
