Abstract
A method in a Gateway General packet radio service Support Node, GGSN, for transferring a service identifier from a packet core network to a radio network is provided. The GGSN adds a service identifier in a General packet radio service Tunneling Protocol for User Plane, GTP-U, header extension of a data packet. The service identifier comprises information about what service and/or traffic pattern that the packet concerns. The GGSN sends the data packet with the GTP-U header extension to a radio network.

A method in a Serving General packet radio service Support Node (SGSN) for transferring a Service Identifier from a packet core network to a radio network, wherein the radio network is a Base Station Subsystem (BSS), the method comprising:
- receiving a service identifier in a General packet radio service Tunneling Protocol for User Plane (GTP-U) header extension of a data packet from a Gateway General packet radio service Support Node (GGSN) which Service Identifier is related to a traffic pattern and/or to a type of service for the data packet,
- mapping the Service Identifier to an information element in a DownLink Unitdata Protocol Data Unit (DL-UNITDATA PDU) of a message containing the data packet, and
- transferring the Service Identifier in the DL-UNITDATA PDU to the BSS.
A Serving General packet radio service Support Node (SGSN) for transferring a service identifier from a packet core network to a radio network, wherein the radio network is a Base Station Subsystem (BSS), the SGSN comprising:
- a receiver, configured to receive a service identifier in a General packet radio service Tunneling Protocol for User Plane (GTP-U) header extension of a data packet from a Gateway General packet radio service Support Node (GGSN) which service identifier is related to a traffic pattern and/or to a type of service for the data packet,
- a mapping unit, configured to map the service identifier to an information element in a DownLink unitdata Protocol Data Unit (DL-UNITDATA PDU) of a message containing the data packet, and
- a transferring unit, configured to transfer the service identifier in the DL-UNITDATA PDU to the BSS.
A method in a Base Station Subsystem (BSS) for receiving a service identifier from a packet core network, the method comprising:
- receiving a service identifier in a DownLink unitdata Protocol Data Unit (DL-UNITDATA PDU) of a message containing a data packet from a Serving General packet radio service Support Node (SGSN) which service identifier is related to a traffic pattern and/or to a type of service for the data packet.
A Base Station Subsystem (BSS) for receiving a Service Identifier from a packet core network, the BSS node comprising:
- a receiver configured to receive a Service Identifier in a DownLink unitdata Protocol Data Unit (DL-UNITDATA PDU) of a message containing a data packet from a Serving General packet radio service Support Node (SGSN) which service identifier is related to a traffic pattern and/or to a type of service for the data packet.
