Abstract
A system to promote connectivity for inter-radio access technology (RAT) handover from a first radio access network (RAN) to a second radio access network (RAN) is provided. The system comprises a component configured such that for each access point name (APN) in communication with the first radio access network (RAN), the maximum bit rate (MBR) for each active non-guaranteed bit rate (non-GBR) bearer in the second radio access network (RAN) is determined based on each respective access point name's (APN's) used aggregate maximum bit rate (AMBR) and the number of active non-guaranteed bit rate(s) (non-GBR) bearers for the respective access point name (APN).

A method for quality of service (QoS) parameters mapping during a handover from a first radio access network (RAN) to a second RAN, the first RAN and the second RAN having communication with an access point name (APN), comprising:
- deriving, for the second RAN, an APN aggregated maximum bit rate (APN-AMBR) for the APN based on a maximum bit rate (MBR) of a packet data protocol (PDP) context of the first RAN associated with the APN, the first RAN including one of a universal terrestrial radio access network (UTRAN) or a global system for mobiles (GSM) enhanced data for GSM evolution radio access network (GERAN) and the second RAN including an evolved universal terrestrial radio access network (E-UTRAN);
- providing a local user equipment (UE) aggregated maximum bit rate (UE-AMBR) until a subscribed UE-AMBR is available for the UE;
- acquiring the subscribed UE-AMBR;
- calculating a derived UE-AMBR by taking the minimum of the subscribed UE-AMBR and the sum of the derived APN-AMBRs of all APNs associated with the UE;
- comparing the derived UE-AMBR to the local UE-AMBR;
- and
- notifying the derived UE-AMBR to the second RAN by initiating a subscribed quality of service (QoS) modification procedure if the local UE-AMBR is different from the derived UE-AMBR.
A device configured to provide quality of service (QoS) parameters mapping during a handover from a first radio access network (RAN) to a second RAN, the first RAN and the second RAN having communication with an access point name (APN), the device comprising:
- one or more hardware processors configured to:
- derive, for the second RAN, an APN aggregated maximum bit rate (APN-AMBR) for the APN based on a maximum bit rate (MBR) of a packet data protocol (PDP) context of the first RAN associated with the APN, the first RAN including one of a universal terrestrial radio access network (UTRAN) or a global system for mobiles (GSM) enhanced data for GSM evolution radio access network (GERAN) and the second RAN including an evolved universal terrestrial radio access network (E-UTRAN);
- provide a local user equipment (UE) aggregated maximum bit rate (UE-AMBR) until a subscribed UE-AMBR is available for the UE;
- acquire the subscribed UE-AMBR;
- calculate a derived UE-AMBR by taking the minimum of the subscribed UE-AMBR and the sum of the derived APN-AMBRs of all APNs associated with the UE;
- compare the derived UE-AMBR to the local UE-AMBR;
- and
- notify the derived UE-AMBR to the second RAN by initiating a subscribed quality of service (QoS) modification procedure if the local UE-AMBR is different from the derived UE-AMBR.
