Methods and nodes for handling updated subscriber data

A method in a second mobility management node for handling updated subscriber data associated with a User Equipment, UE wherein the updated subscriber data comprises Quality of Service, QoS, parameters, the method comprising:

• determining that the UE has become reachable by the second mobility management node when a Paging Proceed Flag, PPF, associated with the UE is cleared;
• receiving, from a first mobility management node, information indicating that there is updated subscriber data waiting to be transmitted to a gateway node where a transmission of the updated subscriber data to the gateway node was postponed by the first mobility management node because the UE was unreachable;
• receiving the updated subscriber data from a subscriber database, wherein at least part of the updated subscriber data is modified;
• and
• transmitting the updated subscriber data to the gateway node.

A first mobility management node for handling updated subscriber data associated with a User Equipment, UE wherein the updated subscriber data comprises Quality of Service, QoS, parameters, the UE being currently unreachable by the first mobility management node, the first mobility management node being configured to:

• receive, from a subscriber database, updated subscriber data associated with the UE, wherein at least part of the updated subscriber data is modified;
• and to
• determine that transmission of the updated subscriber data to a gateway node should be postponed until the UE has become reachable;
• where the UE is unreachable by the first mobility management node because a Paging Proceed Flag, PPF, associated with the UE is cleared in the first mobility management node.

• receive, from a first mobility management node, information indicating that there is updated subscriber data waiting to be transmitted to a gateway node where a transmission of the updated subscriber data to the gateway node was postponed by the first mobility management node because the UE was unreachable;
• receive the updated subscriber data from a subscriber database, wherein at least part of the updated subscriber data is modified;
• and
• transmit the updated subscriber data to the gateway node.
