Abstract
A method performed by a target network node for interworking handover from an evolved packet system, EPS, to a fifth generation system, 5GS, in a mobile network is provided. The method includes receiving, from a source network node, a determined user plane, UP, encryption policy. The method further includes providing the determined UP encryption policy to a target radio access network node. Corresponding embodiments for methods performed by a source network node and a first target network node are also provided.
Claims22
A method performed by a target network node for interworking handover from an evolved packet system, EPS, to a fifth generation system, 5GS, in a mobile network, the method comprising:
- receiving, from a source network node, a determined user plane, UP, encryption policy;
- and
- providing (1203) the determined UP encryption policy to a target radio access network node.
A method performed by a source network node for interworking handover from an evolved packet system, EPS, to a fifth generation system, 5GS, in a mobile network, the method comprising:
- determining a user plane, UP, encryption policy based on a policy configured locally in the source network node per each radio bearer to be handed over to the 5GS;
- and
- forwarding the UP encryption policy towards a target network node.
A method performed by a first target network node for interworking handover from an evolved packet system, EPS, to a fifth generation system, 5GS, in a mobile network, the method comprising:
- receiving a request for a packet data unit session, PDU session, from a second target network node, the request including the UP encryption policy per radio bearer to be handed over to the 5GS;
- determining a determined user plane, UP, encryption policy per each radio bearer to be handed over to the 5GS;
- and
- sending the determined UP encryption policy towards a second target network node.
17-25. (canceled)
A method performed by a first target network node for interworking handover from an evolved packet system, EPS, to a fifth generation system, 5GS, in a mobile network, the method comprising:
- when no UP encryption policy is received from a source network node, determining a user plane, UP, encryption policy;
- and
- providing the determined UP encryption policy to a second target network node.
30-47. (canceled)
