Claims

1-24. -24. (canceled)

25. A method performed in a Radio Network Controller (RNC) in a radio communication network including at least one RNC and at least one Radio Base Station (RBS) and a plurality of user equipments (UEs), the method comprising:

receiving a message that includes information about a number of users for Enhanced Uplink (EUL) or High Speed Downlink Packet Access (HSDPA), or both, for said RBS;

using said information for the RNC'"'"'s capacity management.

26. The method of claim 25, wherein said information includes an allowed maximum number of users for EUL or HSDPA, or both, for said RBS.

27. The method of claim 26, further comprising:

comparing said allowed maximum number of users of EUL or HSDPA, or both, with a corresponding configured value or values for a maximum number of users in said RNC of EUL or HSDPA, or both; and

setting an admission control value or values for a maximum number of users of EUL or HSDPA, or both, to the smaller of the allowed maximum number or numbers and the corresponding configured value or values.

28. The method of claim 26, wherein said message is an AUDIT RESPONSE message or a RESOURCE STATUS INFORMATION message.

29. The method of claim 27, further comprising:

generating an alarm indicating that said allowed maximum number of users of EUL or HSDPA, or both, for said RBS, is less than said configured value of maximum number of users in said RNC of EUL or HSDPA, or both, in the event that the number of users of EUL or HSDPA, or both, in said message is smaller than said configured value of maximum number of user in said RNC of EUL or HSDPA, or both, correspondingly.

30. The method of claim 25, wherein said information includes a failure cause indicating that said allowed maximum number of users of EUL or HSDPA, or both, for said RBS, is less than said configured value for a maximum number of users in said RNC of EUL or HSDPA, or both, correspondingly.

31. The method of claim 30, wherein said message is a RADIO LINK SETUP FAILURE message or a RADIO LINK ADDITION FAILURE message or a RADIO LINK RECONFIGURATION FAILURE message.

32. The method of claim 30, further comprising:

checking an exact failure cause from said information; and

generating an alarm telling the exact failure cause.

33. The method of claim 32, further comprising, when said message corresponds to a request to configure both EUL and HSDPA radio links and it is determined in the checking step that only said EUL radio link configuration failed due to limitation of said allowed maximum number of users of EUL or HSDPA, or both, for said RBS:

requesting to configure one or more HSDPA radio links; and

said exact failure cause is that said allowed maximum number of users of EUL or HSDPA, or both, for said RBS, is less than said configured value for a maximum number of users in said RNC of EUL or HSDPA, or both.

34. The method of claim 32, further comprising suggesting actions to expand said allowed maximum number of users of EUL or HSDPA, or both, for said RBS, correspondingly.

35. The method of claim 34, wherein said actions are ordering higher capacity license for HSDPA or EUL use or expanding configured value for said allowed maximum number of users of EUL or HSDPA, or both, for said RBS.

36. A Radio Network Controller (RNC) in a radio communication network including at least one RNC and at least one Radio Base Station (RBS) and a plurality of user equipments (UEs), the RNC comprising:

a transceiver configured to send and receive messages, and in particular to receive a message that has information about a number of users for Enhanced Uplink (EUL) or High Speed Downlink Packet Access (HSDPA), or both, for said RBS;

a storage configured to store information used by said RNC;

a processor configured to use, for capacity management, said information about a number of users for Enhanced Uplink (EUL) or High Speed Downlink Packet Access (HSDPA), or both, for said RBS.

37. The device of claim 36, wherein said processor further comprises:

a comparer configured to compare, correspondingly, an allowed maximum number of users of EUL or HSDPA, or both, for said RBS, with a configured value for a maximum number of users in said RNC of EUL or HSDPA, or both, stored in said storage, in the event that said information about a number of users for Enhanced Uplink (EUL) or High Speed Downlink Packet Access (HSDPA), or both, for said RBS is said allowed maximum number of users of EUL or HSDPA, or both, for said RBS; and

a setter configured to set an admission control value or values for a maximum number of users of EUL or HSDPA, or both, to the corresponding smaller one or ones of the allowed maximum number and configured value.

38. The device of claim 36, further comprising:

a checker configured to check an exact failure cause in case that said information is a failure cause indicating that the allowed maximum number of users of EUL or HSDPA, or both, for said RBS is less than said configured value of maximum number of user in said RNC of EUL or HSDPA, or both, correspondingly.

39. The device of claim 37, further comprising:

an alarm configured to generate an alarm indicating that said allowed maximum number of users of EUL or HSDPA, or both, for said RBS is less than said configured value of maximum number of user in said RNC of EUL or HSDPA, or both, in case that said comparer has determined that said allowed maximum number of users of EUL or HSDPA, or both, for said RBS is less than said configured value of maximum number of user in said RNC of EUL or HSDPA, or both, correspondingly, or in case that said checker has checked that the exact failure cause is that said allowed maximum number of users of EUL or HSDPA, or both, for said RBS is less than said configured value of maximum number of user in said RNC of EUL or HSDPA, or both, correspondingly.

40. The device of claim 39, wherein if said failure cause corresponds to a request to configure both EUL and HSDPA radio links, and if it is determined by the checker that only said EUL radio link configuration failed due to limitation of said allowed maximum of EUL user number of said RBS, then:

said transceiver is further configured to request to configure one or more HSDPA radio links, and

said alarm is configured to generate an alarm indicating that said allowed maximum of EUL user number of said RBS is less than said configured value for a maximum number of users in said RNC of EUL or HSDPA, or both.

41. The device of claim 39, further comprising:

a suggester configured to suggest actions to expand said allowed maximum number of users of EUL or HSDPA, or both, for said RBS, correspondingly.
