Abstract
A method in a terminal for inter RAT access selection is provided. The terminal is capable to operate in one or more RATs. The terminal receives (201) (202), from a network node, one or more dedicated parameters relating to inter RAT access selection, and one or more broadcasted parameters relating to inter RAT access selection. The one or more broadcasted parameters correspond to the respective one or more dedicated parameters. The one or more broadcasted parameters relates to inter RAT access selection. The terminal then acts (203) for inter RAT access selection according to any one out of: �one or more updated dedicated parameters, updated based on changes to corresponding one or more broadcast parameters, and�any one out of the one or more received dedicated parameters, updated dedicated parameters, or corresponding broadcasted parameters, based on whether one or more conditions are fulfilled or not.

Claim
1. A terminal for inter-RAT access selection, the terminal being capable to operate in one or more Radio Access Technologies (RATs), wherein the terminal comprises:
a transceiver configured to transmit and receive radio signals, and
a processing circuit configured to:
receive from a network node, one or more dedicated parameters comprising one or more thresholds for inter-RAT access selection,
receive from the network node, one or more broadcasted parameters comprising one or more thresholds for inter-RAT access selection, wherein the one or more broadcasted parameters at least partly correspond to the respective one or more dedicated parameters; and
act for inter-RAT access selection according to any one out of:
one or more updated dedicated parameters, updated based on changes to corresponding one or more broadcast parameters; and
any one out of the one or more received dedicated parameters, updated dedicated parameters, or corresponding broadcasted parameters, based on whether one or more conditions are fulfilled or not.
2. The terminal of claim 1, wherein the processing circuit further is configured to act for inter-RAT access selection according to the one or more received dedicated parameters, updated dedicated parameters, or corresponding broadcasted parameters, based on whether one or more conditions are fulfilled or not, comprises one or more out of:
when one or more conditions are fulfilled, continuing to act according to the one or more received dedicated parameters;
when the one or more conditions are fulfilled, act according to one or more updated dedicated parameters, updated based on changes to corresponding one or more broadcast parameters;
when the one or more conditions are not fulfilled or are no longer fulfilled, consider the one or more dedicated parameters obsolete;
when the one or more conditions are not fulfilled or are no longer fulfilled, act according to one or more updated dedicated parameters, updated based on changes to corresponding one or more broadcast parameters; and
when the one or more conditions are not fulfilled or are no longer fulfilled, act according to the corresponding broadcasted parameters.
3. The terminal of claim 1, wherein the terminal has changed cell from a first cell to a second cell, wherein the terminal has received an indication from a network node, which indication relates to a set of cells, and wherein the one or more conditions for acting for inter-RAT access selection comprise whether or not the second cell is one of the cells in the set of cells.
4. The terminal of claim 1, wherein the conditions are any one or more out of:
conditions relating to parameters of a second cell, after the terminal has changed cell from a first cell to the second cell;
conditions relating to the broadcast parameters being changed; and
conditions relating to the terminal having performed less than a number of cell changes since the dedicated threshold was received.
5. The terminal of claim 2, wherein the one or more dedicated parameters are considered obsolete, the terminal further being configured to act according to the received broadcasted parameters.
6. The terminal of claim 2, wherein the processing circuit is configured to considering the one or more dedicated parameters obsolete, the processing circuit further being configured to acquire one or more new dedicated parameters by a Radio Access network (RAN).
7. The terminal according to of claim 1, wherein the processing circuit further is configured to act for inter-RAT access selection when the terminal is not able to receive or is configured not to receive dedicated parameters any more.
8. The terminal of claim 1, wherein the processing circuit further is configured to act for inter-RAT access selection comprising to update the one or more dedicated parameters by considering a change of the corresponding one or more broadcasted parameters.
9. The terminal of claim 8, wherein the one or more dedicated parameters are updated by multiplying a change of the broadcasted threshold with a scaling factor.
10. The terminal of claim 1, wherein the one or more conditions comprises that the broadcasted one or more parameters in the second cell corresponding to the one or more dedicated parameters is equal to, or is within a threshold amount of, the one or more broadcasted parameters of the first cell in which the dedicated thresholds were received.
