Abstract

Various communication systems may benefit from appropriate selection of frequencies for measurement purposes. For example, certain wireless communication systems that can use numerous frequencies but measure a smaller number of frequencies, may benefit from enhanced frequency selection. A method can include identifying a set of possible frequencies for measurement by a user equipment. The method can also include selecting a subset of frequencies from the possible frequencies based on parameters configured by an operator. The method can additionally include causing communication of the selection to the user equipment in a list.

First claim

We claim:

1. A method implemented in a processor of an access node, comprising:
identifying a set of possible frequencies for measurement by a user equipment in a mobile communication network;
selecting a subset of frequencies from the possible frequencies based on parameters configured by a mobile network operator; and
causing a communication of the selection to the user equipment in a list.

2. The method of claim 1 , further comprising:
receiving the parameters from a management system.

3. The method of claim 1 , wherein the parameters comprise a group profile.

4. The method of claim 3 , wherein the group profile comprises at least one of: a group priority, a group size and a frequency selection method.

5. The method of claim 4 , wherein the group priority is configured to determine a position of a group of frequencies in the list relative to other groups of frequencies.

6. The method of claim 4 , wherein the group size is configured to determine a number of reserved places for frequencies of a corresponding group.

7. The method of claim 4 , wherein the frequency selection method is configured to determine how frequencies of a corresponding group are selected.

8. The method of claim 4 , wherein the frequency selection method comprises at least one of fixed order within group, equal priority random selection, or weighted probability random selection.

9. An access node, comprising:
at least one processor; and
at least one memory including computer program code,
wherein the at least one memory and the computer program code are configured to, with the at least one processor cause the access node at least to
identify a set of possible frequencies for measurement by a user equipment in a mobile communication network;
select a subset of frequencies from the possible frequencies based on parameters configured by a mobile network operator; and
cause communication of the selection to the user equipment in a list.

10. The access node of claim 9 , wherein the at least one memory and the computer program code are configured to, with the at least one processor cause the access node at least to receive the parameters from a management system.

11. The access node of claim 9 , wherein the parameters comprise a group profile.

12. The access node of claim 11 , wherein the group profile comprises at least one of: a group priority, a group size and a frequency selection method.

13. The access node of claim 12 , wherein the group priority is configured to determine a position of a group of frequencies in the list relative to other groups of frequencies.

14. The access node of claim 12 , wherein the group size is configured to determine a number of reserved places for frequencies of a corresponding group.

15. The access node of claim 12 , wherein the frequency selection method is configured to determine how frequencies of a corresponding group are selected.

16. The access node of claim 12 , wherein the frequency selection method comprises at least one of fixed order within group, equal priority random selection, or weighted probability random selection.

17. A management system, comprising:
at least one processor; and
at least one memory including computer program code,
wherein the at least one memory and the computer program code are configured to, with the at least one processor cause the management system at least to
group available frequencies for measurement by a user equipment in a mobile communication network into a plurality of groups; and
configure parameters to an access node for selecting frequencies for measurement based on groups.

18. The management system of claim 17 , wherein the parameters comprise at least one of group of a frequency, priority of a frequency, group priority, group size, or selection method.

19. The management system of claim 17 , wherein the parameters form at least one group profile.

20. The management system of claim 19 , wherein the group profile comprises at least one of: a group priority, a group size and a frequency selection method.
