Abstract
Abstract Apparatus, and an associated method, facilitates service degradation in a radio communication system, such as a cellular communication system. A service degradation profile is created and includes values of QoS (quality of service) level values. If communication at levels corresponding to the values of the desired QoS level parameters is unavailable, efforts are made to effectuate, or maintain communication at quality levels corresponding to values of at least first QoS level parameters values. Service degradation thereby occurs pursuant to a selected profile, reducing the need for service renegotiations and reducing the possibility that an abrupt termination of a communication session might occur.

first-communication-service degraded QoS level at which the
communications pursuant to the first communication service are to be
maintained and a first selected second-communication-service
degraded QoS level at which the communications pursuant to the
second communication service are to be maintained.
Claim 6
Independent Claim
50 words
The apparatus of any of claims 1 to 5 wherein the at least
the first communication service comprises a video conference service
and wherein the first selected degraded QoS level of which the
indication thereof is stored at said service subscription register

level.
Claim 7
Dependent Claim
21 words
The apparatus of claim 6 wherein the first selected video-conference-service
degraded QoS level comprises a first selected
degraded data QoS level.
Claim 8

degraded QoS level comprises a first selected
degraded video QoS level.
Claim 9
Dependent Claim
