A radio communication device and method therefor

摘要

This invention relates to a method and apparatus for allocating a device address to a communication device and/or transmitting data to a communication device having a device address. A mobile communication device assigns itself a device address by performing the step of determining the device address at least partly in response to a position of the mobile communication device. A base station 209 transmits data to the mobile communication device by performing the steps of determining a target location area 211; determining a device address at least partly in response to the target location area 211; and then transmitting the data using the device address. The invention is particularly applicable to cellular communication systems.
