The invention describes a methods of enabling and performing location-based services especially geomessaging. The invention describes in detail a flexible combination of multicast Internet protocol addresses and area codes in order to generate geomessaging Internet protocol addresses. The geomessaging Internet protocol address enables to receive by means of a mobile communication device (300) according to the invention geomessages and to submit the geomessages by means of the geomessaging network entity (400) according to the invention. No signaling between the mobile communication device (300) and the network or any service provider within the network is necessary to specify the current location of the mobile communication device. Furthermore, there is no need for a geomessaging message provider to know which mobile communication device is currently located within a specific first area.
A method of performing a location-based service by means of a mobile communication device, the method comprising the steps of:
A mobile communication device comprising a mobile radio module, a mobile location determination module, a mobile processing device and a mobile memory device, wherein the mobile location determination module is adapted to determine an area, wherein the mobile communication device is adapted to assign an area code to the area for identifying at least a part of the area, wherein the mobile processing device is adapted to readout a multicast Internet protocol address from the mobile memory device, wherein the mobile processing device is further adapted to generate a geomessaging Internet protocol address by integrating at least a part of the area code in the multicast Internet protocol address, wherein the mobile communication device is adapted to identify at least one communication item by means of the geomessaging Internet protocol address, wherein the mobile communication device is adapted to receive the communication item via the mobile radio module, wherein the mobile communication device is adapted to determine a movement profile of the mobile communication device;
A method of performing a location-based service by means of a geomessaging network entity, the method comprising the steps of:
A geomessaging network entity comprising a communication interface, a location determination module, a processing device, a memory device and a communication interface, wherein the communication interface is adapted to receive at least one communication item based on an area, wherein the location determination module is adapted to determine the area by means of an identification of a geomessaging message provider, wherein the geomessaging network entity received the communication item from the geomessaging message provider, wherein the geomessaging network entity is adapted to assign an area code to at least a part of an area, wherein the area is based on at least a part of the area, wherein the processing device is adapted to read out a multicast Internet protocol address from the memory device based on the communication item, wherein the processing device is further adapted to generate a geomessaging Internet protocol address by integrating at least a part of the area code in a multicast Internet protocol address, wherein the communication interface of the geomessaging network entity is adapted to transmit a communication item by means of the geomessaging Internet protocol address.
