Abstract

A method for creating a radio resource control profile for a radio resource allocation or a state-transition profile having the steps of: receiving a parameter associated with a user equipment (UE); associating the parameter with the radio resource control profile for the radio resource allocation or the state-transition profile; and initiating the radio resource allocation or state transition profile for the UE.

Claims

1. A method for dynamic resource allocation in a Radio Resource Control (RRC) layer comprising:

using a resource control profile to define radio resource allocation and state-transitions for a user equipment (UE);

during operation of the UE, modifying the radio resource allocation or state-transitions defined by the resource control profile based on information associated with the UE, the information being a parameter specified by the UE; and

comparing the specified parameter with any previously received parameter from the UE, each parameter having a different transition profile with a transition period from an RRC state associated therewith,

wherein the modifying step includes selecting the transition profile based on the parameter having the longest transition period.

2. The method of claim 1, said modifying including customizing the resource control profile wherein at least one of thresholds for transitioning from one to another of predetermined number of states is changed.

3. The method of claim 1, including controlling the UE with the modified resource control profile.

4. The method of claim 1, the resource control profile defining resource and inactivity thresholds for transitioning from one to another of a predetermined number of states.

5. The method of claim 1, including associating the parameter with a radio resource allocation profile or a state-transition profile.

6. The method of claim 5, wherein the associating step comprises looking up the parameter in a look-up table or database and finding a corresponding radio resource allocation or state transition profile.

7. The method of claim 6, wherein the look-up table or database is stored on the UTRAN.

8. The method of claim 6, wherein the look-up table or database is stored remotely from the UTRAN.

9. The method of claim 1, wherein the parameter is received from one of the UE, a network entity and a Home Location Register (HLR) or a dedicated message.

10. The method of claim 1, wherein the parameter is one of an Access Point Name (APN) used to create a Packet Data Protocol (PDP) context, a Quality of Service parameter set by the UE, a Quality of Service allocation retention priority parameter, a subscription profile of the UE or specified by the UE indicative of subscription for which an RRC connection is to be established.

11. The method of claim 1, further comprising checking whether a PDP context associated with the received parameter has radio resources allocated to it, and if no, ignoring the parameter.

12. The method of claim 1, wherein the radio resource allocation profile comprises an allocation selected from the group consisting of:

rate adaptation algorithms including periodicity of step and step size;

initial granted radio bearer;

maximal granted radio bearer;

minimize call setup time by avoiding unnecessary steps such as traffic volume measurements; and

allocation between different radio access technologies.

13. A UTRAN in a UMTS network, the UTRAN configured to:

use a resource control profile to define radio resource allocation and state-transitions for a user equipment (UE);

during operation of the UE, modify the radio resource allocation or state-transitions defined by the resource control profile based on information associated with the UE, the information being a parameter specified by the UE; and

compare the specified parameter with any previously received parameter from the UE, each parameter having a different transition profile with a transition period from an RRC state associated therewith,

wherein the modifying includes selecting the transition profile based on the parameter having the longest transition period.

14. The UTRAN of claim 13, wherein the modifying including customizing the resource control profile wherein at least one of thresholds for transitioning from one to another of predetermined number of states is changed.

15. A user equipment (UE) adapted to facilitate for dynamic resource allocation in a Radio Resource Control (RRC) layer the UE configured to:

use a resource control profile to define radio resource allocation and state-transitions for a user equipment (UE);

during operation of the UE, modify the radio resource allocation or state-transitions defined by the resource control profile based on information associated with the UE, the information being a parameter specified by the UE; and

compare the specified parameter with any previously received parameter, each parameter having a different transition profile with a transition period from an RRC state associated therewith,

wherein the modifying includes selecting the transition profile based on the parameter haying the longest transition period.

16. The UE of claim 15, wherein the modifying including customizing the resource control profile wherein at least one of thresholds for transitioning from one to another of predetermined number of states is changed.
