Abstract: A method of assisting an end user is provides. A first assistance request signal is received from a communication device. A communication node determines an assistance center in close proximity to the communication device to provide assistance to the end user. The communication node then forwards a second assistance request signal to the assistance center. The communication node receives a first response signal from assistance center. Finally, the communication node transmits a second response signal to the communication device.
