Abstract
The embodiments herein relate to a method in a first mobility management node (108a) for handling updated subscriber data associated with a UE (101). The UE (101) is currently unreachable by the first mobility management node (108a). The first mobility management node (108a) receives, from a subscriber database (128), updated subscriber data associated with the UE (101). At least part of the updated subscriber data is modified. The first mobility management node (108a) determines that transmission of the updated subscriber data to a gateway node (110) should be postponed until the UE (101) has become reachable.
Claims28
A method in a first mobility management node for handling updated subscriber data associated with a User Equipment, UE, the UE being currently unreachable by the first mobility management node and wherein the updated subscriber data comprises Quality of Service, QoS, parameters, the method comprising:
- receiving, from a subscriber database, updated subscriber data associated with the UE, wherein at least part of the updated subscriber data is modified;
- and
- postponing transmission of the updated subscriber data to a gateway node until the UE has become reachable;
- determining that the UE has become reachable by one of a group consisting of:
- the first mobility management node;
- and
- a second mobility management node;
- and
- transmitting to one of a group consisting of:
- to the gateway node, at least the part of the updated subscriber data which is modified;
- and
- to the second mobility management node, information that there is updated subscriber data waiting to be transmitted to the gateway node.
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;
- receiving, by the second mobility management node, from a first mobility management node, an indication indicating that there is updated subscriber data, received by the first mobility management node, 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, by the second mobility management node, the updated subscriber data from a subscriber database, wherein at least part of the updated subscriber data is modified;
- transmitting, by the second mobility management node, the updated subscriber data to the gateway node;
- and
- clearing, by the second mobility management node, the indication when the updated subscriber data has been transmitted 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
- postpone transmission of the updated subscriber data to a gateway node until the UE has become reachable;
- determine that the UE has become reachable by one of a group consisting of:
- the first mobility management node;
- and a second mobility management node;
- and
- transmit to one of a group consisting of:
- to the gateway node, at least the part of the updated subscriber data which is modified;
- and
- to the second mobility management node, information that there is updated subscriber data waiting to be transmitted to the gateway node.
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 second mobility management node being configured to:
- determine that the UE has become reachable by the second mobility management node;
- receive, by the second mobility management node, from a first mobility management node, an indication indicating that there is updated subscriber data, received by the first mobility management node, 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, by the second mobility management node, the updated subscriber data from a subscriber database, wherein at least part of the updated subscriber data is modified;
- transmit by the second mobility management node, the updated subscriber data to the gateway node;
- and
- clear, by the second mobility management node, the indication when the updated subscriber data has been transmitted to the gateway node.
