A UMTS (Universal Mobile Telecommunications System) core network supports the negotiation of variable quality of service (QoS). A QoS information element (IE) is defined that supports downgradeable QoS requirements by allowing multiple traffic classes to be specified in a priority order. Similarly, a QoS information element (IE) is defined that supports upgradeable QoS requirements.

A location based Quality of Service (QoS) is negotiated for each mobile terminal entering a mobile network. Each mobile terminal receives a routing area identification that identifies the mobile terminal's location. The routing area identification and International Mobile Subscriber Identity (IMSI) are transmitted to a QoS selection block within a QoS network element to map the mobile terminal to a QoS group and a corresponding QoS profile. The QoS selection block provides a selected QoS based on the QoS profile to the network element wherein the selected QoS rating is negotiated with the mobile terminal. The QoS negotiation includes using the selected QoS rating when the mobile terminal routing area maps to one of the corresponding QoS groups or using a subscribed QoS rating received from the roaming mobile terminal HLR when the mobile terminal routing area and IMSI do not map to one of the corresponding QoS groups.

The present invention discloses a system and a method of dynamic QoS negotiation in NGN. The Resource and Admission Control Subsystem (RACS) provides intercommunication interfaces with Transport functional (TF) entity, Service Control Functional (SCF) entities, and Network Attachment Subsystem (NASS), and thereby, when a user terminal in NGN is to develop a service with QoS requirement, the RACS can obtain the QoS requirement parameters of a service, determine the admission control decision parameters in accordance with the QoS requirement parameters, and the RACS send the determined admission control decision parameters to the TF entity for execution, such that the QoS assurance for the service is realized. The present invention allows an end-to-end QoS negotiation in NGN in accordance with the availability of current transport network resources, and thereby can effectively improve the transport resource utilities. Therefore, the present invention can effectively ensure QoS of service transported in NGN.
