1. A method in a terminal for enabling access to a radio communications network, the method comprising:
- receiving a policy set indicator transmitted from a base station for a cell where the terminal is located, wherein the policy set indicator indicates a set of policies controlling access network selection and traffic steering in the cell;
determining from the policy set indicator whether a current set of policies stored at the terminal apply to the cell;
responsive to determining that the current set of policies apply to the cell, operating in the cell according to an indicated or selected one of the policies in the current set of policies; and
responsive to determining that the current set of policies do not apply to the cell, updating the current set of policies by requesting a policy update from the radio communications network and operating in the cell according to an indicated or selected one of the policies in the updated current set of policies.

Abstract
Embodiments herein disclose a method in a terminal (10) for enabling access to a radio communications network, wherein the terminal (10) is served in a cell of the radio communications network. The terminal (10) receives an indicator from a base station (12), which indicator indicates a set of settings to use in the cell, and the settings relate to access of the radio communications network.

7. A method in a network node for enabling access to a radio communications network, the method comprising:
-
transmitting, for each of one or more cells of the radio communications network, a policy set indicator that indicates a set of policies controlling access network selection and traffic steering in the cell, such that terminals moving between two cells recognize from the policy set indicators respectively transmitted in the two cells whether the two cells use the same policy set or use different policy sets; and transmitting, for each of the one or more cells, information comprising the set of policies used in the cell, in response to receiving a policy update request from a terminal operating in the cell. - View Dependent Claims (8, 9, 10, 11, 12)

19. A network node for enabling access to a radio communications network, the network node comprising:
-
a transceiver; and a processing circuit configured to; transmit via the transceiver, for each of one or more cells of the radio communications network, a policy set indicator that indicates a set of policies controlling access network selection and traffic steering in the cell, such that terminals moving between two cells recognize from the policy set indicators respectively transmitted in the two cells whether the two cells use the same policy set or use different policy sets; and transmit via the transceiver, for each of the one or more cells, information comprising the set of policies used in the cell, in response to receiving a policy update request from a terminal operating in the cell. - View Dependent Claims (20, 21, 22, 23, 24)

25. A method of operation in a terminal configured for operation in a radio communications network, the method comprising:
-
receiving a first policy set indicator for a first cell of the radio communications network and operating in the first cell according to a policy for radio network access and traffic steering included in a first set of policies corresponding to the first policy set indicator; subsequently moving to a second cell of the radio communications network and receiving a second policy set indicator for the second cell of the radio communications network; and responsive to determining that the second policy set indicator differs from the first policy set indicator, adopting a second set of policies corresponding to the second policy set indicator, and operating in the second cell according to a policy for radio network access and traffic steering included in the second set of policies; wherein the first and second sets of policies are among a number of sets of policies, each set of policies defining policies governing radio access network selection and traffic steering by terminals operating in any given cell to which the set of policies applies.
