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 (301,303) 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 (401) a target location area (211); and then transmitting (405) the data using the device address. The invention is particularly applicable to cellular communication systems. |
