Method and apparatus for cognitive radio coexistence
In a non-limiting and exemplary embodiment, a method is provided for sharing secondary cognitive radio resource user related information. A coexistence node receives information on network properties associated with secondary cognitive radio resource users. An upload message is generated and sent, the upload message including for a secondary user database at least information on the received network properties associated with secondary cognitive radio resource users. A location-dependent network map including at least information on network properties is generated. The network map is sent to assist one or more secondary cognitive radio resource users.
1. A method comprising:
receiving, by a coexistence node, information on network properties of a neighboring coexisting network which is not connected to a coexistence manager, wherein the network property information comprises at least one of identification of the neighboring coexisting network and operating parameters of the neighboring coexisting network, and
sending an upload message, the upload message comprising for a secondary user database at least said information on the network properties.
2. The method of claim 1 , wherein the coexistence node generates a communication map on the basis of the received information on network properties, and the coexistence node sends the communication map in the upload message to the secondary user database.
3. The method of claim 1 , further comprising:
receiving, by the coexistence node, information on sensed radio resource usage from one or more secondary cognitive radio users, and
transmitting the information on sensed radio resource usage for the secondary user database.
4. The method of claim 1 , wherein the information on network properties comprises at least one of identification of a secondary user, network identification, type or technology identification, transmit power, operating frequency, priority information, location information, compatibility information, network size information, information on provided services, quality of service information, access establishment related information, and utilization characteristics.
5. The method of claim 3 , wherein the at least one secondary cognitive radio resource user comprises a television white space device.
6. An apparatus comprising:
at least one processor; and
at least one memory including computer program code,
the at least one memory and the computer program code configured, with the at least one processor, to cause the apparatus at least to perform:
receive information on network properties of a neighboring coexisting network which is not connected to a coexistence manager, wherein the network property information comprises at least one of identification of the neighboring coexisting network and operating parameters of the neighboring coexisting network,
send an upload message, the upload message comprising for a secondary user database at least said information on the network properties.
7. An apparatus comprising:
means for receiving information on network properties of a neighboring coexisting network which is not connected to a coexistence manager, wherein the network property information comprises at least one of identification of the neighboring coexisting network and operating parameters of the neighboring coexisting network, and
means for sending an upload message, the upload message comprising for a secondary user database at least said information on the network properties.
8. The apparatus of claim 6 , wherein the at least one memory and the computer program code are further configured, with the at least one processor, to cause the apparatus to generate a communication map on the basis of the received information on network properties, and the apparatus is configured to send the communication map in the upload message to the secondary user database.
9. The apparatus of claim 6 , wherein the at least one memory and the computer program code are further configured, with the at least one processor, to cause the apparatus to receive information on sensed radio resource usage from one or more secondary cognitive radio users, and to transmit the information on sensed radio resource usage for the secondary user database.
10. The apparatus of claim 9 , wherein the at least one memory and the computer program code are further configured, with the at least one processor, to cause the apparatus to function as a coexistence enabler and the one or more secondary cognitive radio resource users are television white space devices.
11. The apparatus of claim 6 , wherein the apparatus is a radio access network device.
12. The apparatus of claim 6 , wherein the information on network properties comprises at least one of identification of a secondary user, network identification, type or technology identification, transmit power, operating frequency, priority information, location information, compatibility information, network size information, information on provided services, quality of service information, access establishment related information, and utilization characteristics.
13. A non-transitory computer readable storage medium comprising one or more sequences of one or more instructions which, when executed by one or more processors of an apparatus, cause the apparatus to perform the steps in claim 1 .
14. An apparatus comprising:
at least one processor; and
at least one memory including computer program code,
the at least one memory and the computer program code configured, with the at least one processor, to cause the apparatus to at least perform the method of claim 1 .
