Abstract

The present disclosure relates to a network entity for a communication network for providing a plurality of communication services to a plurality of mobile communication devices, the network entity comprising: a session manager configured to select a first geographical code from a plurality of geographical codes, wherein each geographical code is associated with a geographical region and wherein the first geographical code is associated with a first geographical region including or close to a current geographical position of at least one of the plurality of mobile communication devices; a encoder configured to encode on a MAC level and/or physical level at least a portion of a message intended for the at least one mobile communication device using the first geographical code; and a communication interface configured to send the message with the portion encoded with the first geographical code to the at least one mobile communication device.

First claim

What is claimed is:

1. A network entity for a communication network, the network entity comprising:
a memory storing a computer program comprising a program code; and
computer hardware configured to execute the computer program to cause the network entity to:
select a first geographical code from a plurality of geographical codes, wherein the first geographical code is associated with a first geographical region including a current geographical position of at least one mobile communication device of a plurality of mobile communication devices, wherein a mapping between the plurality of geographical codes and associated geographical regions is preconfigured in the network entity and the mapping between the plurality of geographical codes and associated geographical regions is preconfigured in the at least one mobile communication device in response to an initial attach procedure, a location update procedure, a handover procedure, or another service request message of the at least one mobile communication device, and wherein the first geographical code is a first geographical radio network temporary identifier (RNTI);
encode, on at least one of a media access control (MAC) level or a physical (PHY) level, at least a portion of a message intended for the at least one mobile communication device based on the first geographical code;
scramble at least a cyclic redundancy check (CRC) portion of the message based on the first geographical code for encoding, on at least one of the MAC level or the PHY level, at least a portion of the message intended for the at least one mobile communication device; and
send the message with the portion encoded based on the first geographical code to the at least one mobile communication device.

2. The network entity of claim 1 , wherein executing the computer program further causes the network entity to:
select a second geographical code from the plurality of geographical codes, wherein the second geographical code is associated with a second geographical region including the current geographical position of the at least one mobile communication device, but different to the first geographical region associated with the first geographical code;
encode, on at least one of the MAC level or the PHY level, at least a portion of the message intended for the at least one mobile communication device based on the second geographical code; and
send the message with the portion encoded based on the second geographical code to the at least one mobile communication device.

3. The network entity of claim 1 , wherein executing the computer program further causes the network entity to:
send to the at least one mobile communication device a subset of the plurality of geographical codes, wherein the subset of the plurality of geographical codes is selected based on information about a future trajectory of the at least one mobile communication device.

4. The network entity of claim 1 , wherein the communication network comprises a plurality of communication cells, wherein each communication cell of the plurality of communication cells is associated with a base station of the communication network, and wherein the first geographical region is defined by a portion of a communication cell of the plurality of communication cells.

5. The network entity of claim 1 , wherein the at least one mobile communication device comprises a first group of mobile communication devices, and wherein executing the computer program further causes the network entity to:
include a first group identifier comprising a temporary mobile group identity in the message with the portion encoded based on the first geographical code, wherein the first group identifier is assigned to at least one of the first group of mobile communication devices or a communication service associated with the first group of mobile communication devices.

6. The network entity of claim 5 , wherein executing the computer program further causes the network entity to:
maintain a mapping between the plurality of geographical codes and a plurality of group identifiers, including the first group identifier; and
select the first group identifier based on the first geographical code and the mapping between the plurality of geographical codes and the plurality of group identifiers.

7. The network entity of claim 1 , wherein the network entity is implemented as a base station or as a part of a base station.

8. The network entity of claim 7 , wherein executing the computer program further causes the network entity to:
send the message to at least one neighboring network entity implemented as a neighboring base station or as a part of a neighboring base station.

9. The network entity of claim 1 , wherein executing the computer program further causes the network entity to:
receive a message from a mobile communication device, wherein at least a portion of the message is encoded on at least one of the MAC level or the PHY level with a further geographical code, wherein the further geographical code is associated with a geographical region including a current geographical position of the at least one mobile communication device; and
decode, on at least one of the MAC level or the PHY level, at least a portion of the message based on the further geographical code.

10. A method of operating a network entity for a communication network, the method comprising:
selecting a first geographical code from a plurality of geographical codes, wherein each geographical code of the plurality of geographical codes is associated with a geographical region, and wherein the first geographical code is associated with a first geographical region including a current geographical position of at least one mobile communication device of a plurality of mobile communication devices, wherein a mapping between the plurality of geographical codes and associated geographical regions is preconfigured in the network entity and the mapping between the plurality of geographical codes and associated geographical regions is preconfigured in the at least one mobile communication device in response to an initial attach procedure, a location update procedure, a handover procedure, or another service request message of the at least one mobile communication device, and wherein the first geographical code is a first geographical radio network temporary identifier (RNTI);
encoding, on at least one of a media access control (MAC) level or a physical (PHY) level, at least a portion of a message intended for the at least one mobile communication device the first geographical code;
scramble at least a cyclic redundancy check (CRC) portion of the message based on the first geographical code for encoding, on at least one of the MAC level or the PHY level, at least a portion of the message intended for the at least one mobile communication device; and
sending the message with the portion encoded based on the first geographical code to the at least one mobile communication device.

11. A mobile communication device configured to use one or more of a plurality of communication services provided by a communication network, the mobile communication device comprising:
a communication interface configured to receive a message from a network entity of the communication network on at least one of a media access control (MAC) level or a physical (PHY) level, wherein at least a portion of the message is encoded based on a first geographical code, wherein the first geographical code is associated with a geographical region including a current geographical position of the mobile communication device, wherein a mapping between the first geographical code and the geographical region is preconfigured in th
