Abstract

The proposed technology relates to the issue of supporting release of common radio resources in a radio communication network. A radio network controller sends an indication of a value of a timer for implicit release of common radio resources to a base station. The base station receives the indication of a value of a timer for implicit release of common radio resources and determines whether to release common radio resources based on the indication of a value of the timer for implicit release of common radio resources. In this way, by using the indication of a value of the timer for implicit release the base station will be able to correctly determine whether to release the common resources upon reception of a report of empty buffer status from a UE. This will eliminate misinterpretations of the empty buffer status report, and avoid unnecessary radio link failures.

First claim

What is claimed is:

1. A method performed by a base station for supporting release of common radio resources in a radio communication network, said method comprising the steps of:
receiving an indication of a value of a timer for implicit release of common radio resources from a radio network controller; and
determining whether to release the common radio resources based on said indication of the value of said timer for implicit release of common radio resources;
wherein said indication is received in a PHYSICAL SHARED CHANNEL RECONFIGURATION REQUEST message.

2. The method of claim 1 , wherein said indication is included in a “Common E-DCH Implicit Release Timer” information element (IE) in said PHYSICAL SHARED CHANNEL RECONFIGURATION REQUEST message.

3. The method of claim 2 , wherein said indication in the “Common E-DCH Implicit Release Timer” IE is defined to be of ENUMERATED type with values zero or more than zero.

4. A method performed by a radio network controller for supporting release of common radio resources in a radio communication network, said method comprising the step of:
said radio network controller sending an indication of a value of a timer for implicit release of common radio resources to a base station, to thereby enable the base station to determine whether to release the common radio resources based on said indication;
wherein said method comprises the step of said radio network controller adding an information element (IE) including said indication to a message, and wherein said step of said radio network controller sending said indication comprises the step of said radio network controller sending said message with said added IE to said base station.

5. The method of claim 4 , wherein said message is PHYSICAL SHARED CHANNEL RECONFIGURATION REQUEST message.

6. The method of claim 5 , wherein said indication is included in a “Common E-DCH Implicit Release Timer” information element (IE) in said PHYSICAL SHARED CHANNEL RECONFIGURATION REQUEST message.

7. The method of claim 6 , wherein said indication in the “Common E-DCH Implicit Release Timer” IE is defined to be of ENUMERATED type with values zero or more than zero.

8. A base station for a radio communication network, wherein said base station comprises:
an interface configured to receive an indication of a value of a timer for implicit release of common radio resources from a radio network controller; and
a processing module configured to determine whether to release common radio resources based on said indication;
wherein said indication indicates a value of a timer for implicit release of common Enhanced Dedicated Channel (E-DCH) resources, and said processing module is configured to determine whether to release common E-DCH resources responsive to the indication; and
wherein said interface is configured to receive said indication in a “Common E-DCH Implicit Release Timer” information element (IE) in a PHYSICAL SHARED CHANNEL RECONFIGURATION REQUEST message.

9. A radio network controller for a radio communication network, wherein said radio network controller comprises an interface configured to send an indication of a value of a timer for implicit release of common radio resources to a base station, to thereby enable the base station to determine whether to release common radio resources based on said indication and wherein said radio network controller comprises a processing module configured to add an information element (IE) including said indication in a message, and wherein said interface is configured to send said message to the base station.

10. The radio network controller of claim 9 , wherein said radio network controller comprises a processing module configured to include said indication in a “Common E-DCH Implicit Release Timer” information element (IE) in a PHYSICAL SHARED CHANNEL RECONFIGURATION REQUEST message, and said interface is configured to send said PHYSICAL SHARED CHANNEL RECONFIGURATION REQUEST message to the base station.
