Abstract:
1. A method for dynamically adjusting an aggregated maximum bit rate ‘AMBR’, comprising: determining whether a change in an AMBR currently applicable to a first network component should be requested; and when a change in the AMBR is requested, the first network component recommending to a second network component a recommended adjusted AMBR; when a first bandwidth consumed by the first network component differs from a second bandwidth specified in the AMBR currently applicable to the first network component, the first network component recommending to the second network component the recommended adjusted AMBR; when the recommended adjusted AMBR is less than an AMBR currently applicable to the second network component, setting the first network component's AMBR and the second network component's AMBR to the recommended adjusted AMBR, and the first network component and the second network component using the recommended adjusted AMBR; when the recommended adjusted AMBR is greater than the AMBR currently applicable to the second network component and where the second network component has bandwidth available to support the recommended adjusted AMBR, setting the first network component's AMBR and the second network component's AMBR to the recommended adjusted AMBR, and the first network component and the second network component using the recommended adjusted AMBR; and when the recommended adjusted AMBR is greater than the AMBR currently applicable to the second network component and where the second network component's bandwidth can not support the recommended adjusted AMBR, the first network component and the second network component negotiate a new adjusted AMBR, setting the first network component's AMBR and the second network component's AMBR to the negotiated new adjusted AMBR, and the first network component and the second network component using the negotiated new adjusted AMBR, and wherein an AMBR defined for a UE is the lesser of a subscribed AMBR, or the available bandwidth of the second network component.
