Abstract
The present invention provides a method for improving Network Discovery and Selection suitable for a UE which is moving into a new TA, which comprises: receiving, by a MMF, a TAU request including the new TA from the UE; allocating, by the MMF, a new TA List according to the new TA in the TAU request; sending, by the MMF, the new TA List to the UE; sending, by the MMF, a TA information to a Mobility Policy Function, MPF, for updating mobility policy of the UE if the new TA is a special TA covered by different networks.

A method for improving Network Discovery and Selection suitable for a User Endpoint (UE), which is moving into a new Tracking Area (TA), comprising:
- receiving, by a Mobility Management Function (MMF), a Tracking Area Update (TAU) request, including the new TA from the UE;
- allocating, by the MMF, a new TA List according to the new TA in the TAU request;
- sending, by the MMF, the new TA List to the UE;
- sending, by the MMF, a TA information to a Mobility Policy Function, MPF, for updating mobility policy of the UE if the new TA is a special TA covered by different networks.
A method for improving Network Discovery and Selection suitable for a User Endpoint, UE, which is moving into a new Tracking Area, TA, comprising:
- receiving, by a Mobility Policy Function, MPF, a TA information for updating mobility policy of the UE;
- updating the mobility policy of the UE if the new TA is a special TA covered by different networks.
A Mobility Management Function (MMF) for improving Network Discovery and Selection suitable for a User Endpoint (UE), which is moving into a new Tracking Area (TA), comprising:
- a receiving unit which is configured to receive a TAU request including a current location of the UE;
- a storing unit which is configured to store network topology information;
- a allocating unit which is configured to generate a new TA list according to the network topology information in the storing unit and the current location of the UE in the TAU request;
- a TA information unit which is configured to send TA information including the new TA list to update a mobility policy.
A Mobility Policy Function (MPF) for improving Network Discovery and Selection suitable for a User Endpoint (UE), which is moving into a new Tracking Area (TA), comprising:
- a receiving unit which is configured to receive TA information to update mobility to the UE;
- a storing unit which is configured to store mobility policies;
- a updating unit which is configured to get an updated policy from the storing unit and send it to the UE if the new TA is a special TA covered by different networks.
