Abstract

The embodiments herein relate to a method in a first mobility management node for handling updated subscriber data associated with a UE. The UE is currently unreachable by the first mobility management node. The first mobility management node receives, from a subscriber database, updated subscriber data associated with the UE. At least part of the updated subscriber data is modified. The first mobility management node determines that transmission of the updated subscriber data to a gateway node should be postponed until the UE has become reachable.

Claims

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

determining that transmission of the updated subscriber data to a gateway node should be postponed until the UE has become reachable.

2. The method according to claim 1, further comprising:

setting an indication indicating that there is updated subscriber data waiting to be transmitted to the gateway node.

3. The method according to claim 2, further comprising:

clearing the indication when the at least part of the updated subscriber data which is modified has been transmitted to the gateway node.

4. The method according to claim 1, further comprising:

determining that the UE has become reachable by the first mobility management node; and

transmitting at least the part of the updated subscriber data which is modified to the gateway node.

5. The method according to claim 1, further comprising:

determining, that the UE has become reachable by a second mobility management node; and

transmitting, to the second mobility node, information about that there is updated subscriber data waiting to be transmitted to the gateway node.

6. The method according to claim 5, wherein the information transmitted to the second mobility node is an indication indicating that there is updated subscriber data waiting to be transmitted to the gateway node.

8. The method according to claim 1, wherein the UE is unreachable when the UE is in suspend state or in power saving state or when a Paging Proceed Flag, PPF, associated with the UE is cleared in the first mobility management node.

9. The method according to claim 1, wherein the first mobility management node is a Mobility Management Entity, MME, or a Serving General packet radio service Support Node, SGSN, or a combined MME and SGSN node.

10. The method according to claim 5, wherein the second mobility management node is a Mobility Management Entity, MME, or a Serving General packet radio service Support Node, SGSN, or a combined MME and SGSN node.

11. The method according to claim 1, wherein the gateway node is a Serving GateWay, SGW, or a Packet data network GateWay, PGW or a combined SGW and PGW node.

12. The method according to claim 1, wherein the subscriber database is a Home Subscriber Server, HSS, or a Home Location Register, HLR.

7. (canceled)

13. 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, from a first mobility management node, information about that there is updated subscriber data waiting to be transmitted to a gateway node;

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.

14. The method according to claim 13, wherein the received information is an indication indicating that there is updated subscriber data waiting to be transmitted to the gateway node.

15. The method according to claim 14, further comprising:

clearing the indication when the updated subscriber data has been transmitted to the gateway node.

17. The method according to claim 13,

wherein the first mobility management node is a first Mobility Management Entity, MME, and the second mobility management node is a second MME, or

wherein the first mobility management node is a first Serving General packet radio service Support Node, SGSN, and the second mobility management node is a second SGSN, or

wherein the first mobility management node is a first combined MME and SGSN node and the second mobility management node is a second combined MME and SGSN node.

18. The method according to claim 13, wherein the gateway node is a Serving GateWay, SGW, or a Packet data network GateWay, PGW or a combined SGW and PGW node.

16. (canceled)
