A method in an Access and Mobility Management Function, AMF, comprising, in a 5th Generation System, 5GS, to Evolved Packet System, EPS, handover procedure of a User Equipment, UE:
- receiving, from a Next Generation Radio Access Network, NG-RAN, node, a secondary Radio Access Technology, RAT, usage data report message including a Secondary RAT Usage Data Report Transfer Information Element, IE, containing secondary RAT usage data associated with the UE;
- and
- transmitting, to a Mobility Management Entity, MME, a message including a first IE containing the secondary RAT usage data, wherein the first IE contains a field encoded with content of the Secondary RAT Usage Data Report Transfer IE, and wherein the first IE further contains an EPS Bearer Identifier, EBI, associated with a Protocol Data Unit, PDU, session for the UE.
A method in a Mobility Management Entity, MME, comprising, in a 5th Generation System, 5GS, to Evolved Packet System, EPS, handover procedure of a User Equipment, UE:
- receiving, from an Access and Mobility Management Function, AMF, a first message including a first Information Element, IE, containing secondary Radio Access Technology, RAT, usage data associated with the UE;
- and
- transmitting, to a Session Management Function and Packet Data Network Gateway-Control, SMF+PGW-C, a second message including the first IE, wherein the first IE contains a field encoded with content of a Secondary RAT Usage Data Report Transfer IE, the Secondary RAT Usage Data Report Transfer IE containing the secondary RAT usage data, and wherein the first IE further contains an EPS Bearer Identifier, EBI, associated with a Protocol Data Unit, PDU, session for the UE.
A method in a Session Management Function and Packet Data Network Gateway-Control, SMF+PGW-C, comprising, in a 5th Generation System, 5GS, to Evolved Packet System, EPS, handover procedure of a User Equipment, UE:
- receiving, from a Mobility Management Entity, MME, a message including a first Information Element, IE, containing secondary Radio Access Technology, RAT, usage data associated with the UE, wherein the first IE contains a field encoded with content of a Secondary RAT Usage Data Report Transfer IE, the Secondary RAT Usage Data Report Transfer IE containing the secondary RAT usage data, and wherein the first IE further contains an EPS Bearer Identifier, EBI, associated with a Protocol Data Unit, PDU, session for the UE.
A network node implementing an Access and Mobility Management Function, AME, comprising:
- a communication interface,
- a processor, and
- a memory, the memory comprising instructions that when executed by the processor configure the network node, to facilitate a handover procedure of a User Equipment, UE, by:
- receiving, from a Next Generation Radio Access Network, NG-RAN, node, a secondary Radio Access Technology, RAT, usage data report message including a Secondary RAT Usage Data Report Transfer Information Element, IE, containing secondary RAT usage data associated with the UE;
- and
- transmitting, to a Mobility Management Entity, MME, a message including a first IE containing the secondary RAT usage data, wherein the first IE contains a field encoded with content of the Secondary RAT Usage Data Report Transfer IE, and wherein the first IE further contains an EPS Bearer Identifier, EBI, associated with a Protocol Data Unit, PDU, session for the UE.
