Abstract
The technology pertains to wireless telecommunications systems in which a quality of service is handled for a service provided to a user equipment when the user equipment transitions from being served by a source network to being served by a target network. The quality of service is handled even if the source and the target networks implement proprietary QCIs. In general, a source QCI, which may be proprietary to the source network, is remapped to a predetermined QCI that identifies a set of predetermined QCI characteristics whose values are similar to the source QCI characteristics identified by the source QCI. The predetermined QCI and the set of predetermined QCI characteristics are used by the target network to provide the service to the user equipment after the transition.

26. A method of mapping a quality of service class identifier (QCI) between a source network and a target network for a service provided to a user equipment (UE), comprising:
-
(a) aligning a set of source quality of service (QoS) parameters with a predetermined QCI; and (b) assigning a set of target QoS parameters for a target network based on the predetermined QCI; wherein the set of source QoS parameters is associated with a source service bearer for use by the source network to provide the service to the UE prior to a transition of the UE from being served by the source network to being served by the target network, the predetermined QCI is one of at least one or more preconfigured QCIs, each preconfigured QCI correspondingly identifies a set of preconfigured QCI characteristics, and the set of target QoS parameters is associated with a target service bearer for use by the target network to provide the service to the UE when the transition occurs. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)

43. A mobility controller of a wireless network, comprising:
-
a management unit arranged to manage a transition of a service provided to a user equipment (UE), wherein when the transition of the service is from the wireless network to a target network, the management unit is arranged to align a set of source quality of service (QoS) parameters with a predetermined QoS class identifier (QCI), and to assign a set of target QoS parameters for the target network based on the predetermined QCI; wherein the set of source QoS parameters is associated with a source service bearer for use by the wireless network to provide the service to the UE prior to the transition, the predetermined QCI is one of one or more preconfigured QCIs, each preconfigured QCI correspondingly identifies a set of preconfigured QCI characteristics, and the set of target QoS parameters is associated with a target service bearer for use by the target network to provide the service to the UE when the transition occurs. - View Dependent Claims (44, 45, 46, 47)

48. A mobility controller of a wireless network, comprising:
-
a management unit arranged to remap a set of target Quality of Service (QoS) parameters to a remap set of target QoS parameters when a service provided to a user equipment (UE) is transitioning from a source network to the wireless network; wherein the set of target QoS parameters is assigned by the source network based on a predetermined QCI, the predetermined QCI is one of one or more preconfigured QCIs, each preconfigured QCI correspondingly identifies a set of preconfigured QCI characteristics, the set of remap target QoS parameters is associated with a target service bearer for use by the wireless network to provide the service to the UE when the transition occurs, the remap set of target QoS parameters is applicable to the wireless network and not applicable to the source network, and the predetermined QCI and the corresponding set of QCI characteristics are applicable to both the wireless and the source networks. - View Dependent Claims (49, 50)
