2. The method of claim 1 , wherein the controlling receiving comprises:

controlling receiving, by the user equipment from the base station, the information request including a bitmap that indicates one or more random access procedure trigger types for which random access procedure information is being requested.

3. The method of claim 1 , further comprising:

performing, or attempting to perform, one or more random access procedures; and

controlling sending, by the user equipment to the base station, a random access procedure information availability indicator that indicates that the user equipment has logged the random access procedure information;

wherein the controlling receiving comprises controlling receiving, by the user equipment from the base station in response to the random access procedure information availability indicator.

4. The method of any of claim 1 , wherein the controlling sending a random access procedure report including the random access procedure information is triggered by location-based information at the user equipment.

5. The method of any of claim 1 , further comprising:

controlling sending, by the user equipment to the base station, an extended report ability of the user equipment to send the base station extended random access procedure information for use in a random access procedure optimization process, wherein the extended random access procedure information includes information for more random access procedure parameters and/or information for more random access procedures as compared to a normal random access procedure information.

6. The method of claim 1 , wherein the logging comprises:

creating a log, by a user equipment, of random access procedure information, for each of one or more random access procedure trigger types.

7. 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 to, with the at least one processor, cause the apparatus at least to

log, by a user equipment, random access procedure information for one or more random access procedures of the user equipment;

control receiving, by the user equipment from a base station, an information request including an indication of one or more random access procedure trigger types for which random access procedure information is being requested; and

control sending, by the user equipment to the base station, a random access procedure report including the random access procedure information for the one or more indicated random access procedure trigger types.

8. The apparatus of claim 7 , wherein the controlling receiving comprises:

control receiving, by the user equipment from the base station, the information request including a bitmap that indicates one or more random access procedure trigger types for which random access procedure information is being requested.

9. The apparatus of claim 7 , further comprising:

perform, or attempting to perform, one or more random access procedures; and

controlling sending, by the user equipment to the base station, a random access procedure information availability indicator that indicates that the user equipment has logged the random access procedure information;

wherein the controlling receiving comprises controlling receiving, by the user equipment from the base station in response to the random access procedure information availability indicator.

10. The method of any of claim 7 , wherein the controlling sending a random access procedure report including the random access procedure information is triggered by location-based information at the user equipment.

11. The method of claim 7 , further comprising:

controlling sending, by the user equipment to the base station, an extended report ability of the user equipment to send the base station extended random access procedure information for use in a random access procedure optimization process, wherein the extended random access procedure information includes information for more random access procedure parameters and/or information for more random access procedures as compared to a normal random access procedure information.

12. The method of any of claim 7 , wherein the logging comprises:

creating a log, by a user equipment, of random access procedure information, for each of one or more random access procedure trigger types.

13. A method comprising:

controlling sending, by a base station to a user equipment, an information request for random access procedure information for one or more random access procedures of the user equipment, the information request including an indication of one or more random access procedure trigger types for which random access procedure information is being requested; and

controlling receiving, by the base station from the user equipment, a random access procedure report including the random access procedure information for the one or more indicated random access procedure trigger types.

14. The method of claim 13 , wherein the information request comprises a bitmap that indicates one or more random access procedure trigger types for which random access procedure information is being requested.

15. The method of any of claim 13 , further comprising:

controlling receiving, by the base station from the user equipment, a random access procedure information availability indicator that indicates that the user equipment has logged the random access procedure information;

wherein the controlling sending comprises controlling sending, by the base station, the information request in response to the random access procedure information availability indicator.

16. The method of claim 13 , further comprising:

determining, by the base station based on at least one of the random access procedure report received from the user equipment or the base-station communicated random access procedure information, cost information including a random access procedure cost for each of one or more of the random access procedure trigger types;

adjusting, by the base station based on the cost information, one or more random access procedure parameters or allocation of resources, for at least one of the plurality of random access procedure trigger types.

17. 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 to, with the at least one processor, cause the apparatus at least to

control sending, by a base station to a user equipment, an information request for random access procedure information for one or more random access procedures of the user equipment, the information request including an indication of one or more random access procedure trigger types for which random access procedure information is being requested; and

control receiving, by the base station from the user equipment, a random access procedure report including the random access procedure information for the one or more indicated random access procedure trigger types.

18. The method of claim 17 , wherein the information request comprises a bitmap that indicates one or more random access procedure trigger types for which random access procedure information is being requested.

19. The method of any of claim 17 , further comprising:

control receiving, by the base station from the user equipment, a random access procedure information availability indicator that indicates that the user equipment has logged the random access procedure information;

wherein the controlling sending comprises controlling sending, by the base station, the information request in response to the random access procedure information availability indicator.
