Abstract:
1. 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 source network and the target network have different operators, the predetermined QCI is one of at least one preconfigured QCIs that is recognized by the source and target networks, each preconfigured QCI correspondingly identifies a set of preconfigured QCI characteristics, 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, each preconfigured QCI corresponds to a set of preconfigured QoS parameters; and act (a) comprises: (ac) comparing the set of preconfigured QoS parameters of each preconfigured QCI with the set of source QoS parameters; and (ad) choosing as the predetermined QCI the preconfigured QCI with the corresponding set of preconfigured QoS parameters that minimizes differences with the set of source QoS parameters.
