Abstract

A method is provided for use in a communications network in which a plurality of accesses are available to a user entity for accessing a network resource, comprising: determining a set of active rules, each rule specifying respective preferences, at least relatively, for at least some of the plurality of accesses, with potential for conflict between the rules of the set concerning which access is most preferred; deriving from the set of active rules a new rule specifying respective preferences, at least relatively, for at least some of the plurality of accesses; and selecting an access for use by the user entity based on the new rule.

Claims

1. A method, implemented on a mobile terminal operative in a communications network in which a plurality of accesses are available to the mobile terminal for accessing a network resource, comprising:

determining, by the mobile terminal, a set of active rules, each rule specifying respective preferences, at least relatively, for at least some of the plurality of accesses, the rules of the set being potentially in conflict between each other concerning which access is most preferred, and each rule being assigned a rule-based priority value;

deriving, by the mobile terminal, from the set of active rules a new rule specifying respective preferences, at least relatively, for at least some of the plurality of accesses by selecting, as the new rule, the active rule having the most preferred rule-based priority value; and

selecting an access of the plurality of accesses for use by the mobile terminal based on the new rule.

2. The method of claim 1, further comprising:

accessing the network resource using the selected access.

3. The method of claim 1, further comprising:

scanning for the selected access.

4. The method of claim 3, further comprising:

performing the deriving, selecting and scanning steps for a plurality of sets of active rules.

5. The method of claim 1, wherein the preferences are represented by respective preference values, and wherein deriving a new rule comprises combining the preference values from different rules according to a predetermined scheme to generate the new rule.

6. The method of claim 5, wherein combining the preference values comprises combining the preference values based on the rule-based priority values.

7. The method of claim 6, wherein deriving a new rule comprises weighting the preference values of each active rule based on its assigned priority value, and combining the weighted preference values.

8. The method of claim 6, wherein deriving a new rule comprises deriving the new rule based only on those accesses of the plurality that are considered to be acceptable accesses for all of the active rules.

9. The method of claim 8, wherein deriving a new rule comprises deriving the new rule based on modified respective priority values for the active rules, the priority value modification for each active rule compensating for the non-consideration of at least one of the accesses for that active rule.

10. The method of claim 8, wherein deriving a new rule comprises deriving the new rule based only on those accesses of the plurality that are considered to be acceptable accesses for all of the active rules.

11. The method of claim 5, further comprising determining the preference values from properties of the respective associated accesses.

12. The method of claim 1, wherein the most preferred associated priority value is the highest associated priority value.

13. The method of claim 1, wherein an access of the plurality of accesses is defined by one or more of:

access type, access property parameters, access point ID, access network ID, and core network ID.

14. The method of claim 1, further comprising using the selected access for traffic flows.

15. The method of claim 1, wherein each active rule of the set of active rules is also associated with an actor-based priority value, and wherein the new rule is selected based on the rule-based priority value and the actor-based priority value associated with each active rule.

16. A mobile terminal for communication in a communications network in which a plurality of accesses are available to the mobile terminal for accessing a network resource, comprising a processing circuit configured to:

determine a set of active rules, each rule specifying respective preferences, at least relatively, for at least some of the plurality of accesses, with potential for conflict between the rules of the set concerning which access is most preferred, and each rule being assigned a rule-based priority value;

derive from the set of active rules a new rule specifying respective preferences, at least relatively, for at least some of the plurality of accesses by selecting as the new rule the active rule having the most preferred rule-based priority value; and

select an access of the plurality of accesses for use by the mobile terminal based on the new rule.

17. The mobile terminal of claim 16, wherein the processing circuit is configured to derive a new rule by combining the preference values from different rules according to a predetermined scheme to generate the new rule.

18. The mobile terminal of claim 17, wherein the processing circuit is configured to derive a new rule by combining the preference values based on the priority values.

19. The mobile terminal of claim 18, wherein the processing circuit is configured to weight the preference values of each active rule based on its assigned priority value, and is further configured to combine the weighted preference values.

20. The mobile terminal of claim 18, wherein deriving a new rule comprises deriving the new rule based only on those accesses of the plurality that are considered to be acceptable accesses for all of the active rules.

21. The mobile terminal of claim 20, wherein deriving a new rule comprises deriving the new rule based on modified respective priority values for the active rules, the priority value modification for each active rule compensating for the non-consideration of at least one of the accesses for that active rule.

22. The mobile terminal of claim 20, wherein deriving a new rule comprises deriving the new rule based only on those accesses of the plurality that are considered to be acceptable accesses for all of the active rules.

23. The mobile terminal of claim 16, wherein the most preferred associated rule-based priority value is the highest associated rule-based priority value.

24. The mobile terminal of claim 16, wherein the processing circuit is further configured to access the network resource using the selected access.

25. The mobile terminal of claim 16, wherein the processing circuit is further configured to scan for the selected access.

26. The mobile terminal of claim 25, wherein the processing circuit is further configured to perform the deriving, selecting and scanning steps for a plurality of sets of active rules.

27. The mobile terminal of claim 17, wherein the processing circuit is further configured to determine the preference values from properties of the respective associated accesses.

28. The mobile terminal of claim 16, wherein an access of the plurality of accesses is defined by one or more of:

access type, access property parameters, access point ID, access network ID, and core network ID.

29. The mobile terminal of claim 16, wherein the processing circuit is configured to use the selected access for traffic flows.

30. The mobile terminal of claim 16, wherein each active rule of the set of active rules is also associated with an actor-based priority value, and wherein the new rule is selected based on the rule-based priority value and the actor-based priority value associated with each active rule.

31. A non-transitory machine readable medium including program instructions operative to cause a processor in a mobile terminal of a communications network, in which a plurality of accesses are available to a the mobile terminal for accessing a network resource, to perform the steps of:

determining a set of active rules, each rule specifying respective preferences, at least relatively, for at least some of the plurality of accesses, the rules of the set being potentially in conflict between each other concerning which access is most preferred, each rule being associated with a rule-based priority value;

deriving from the set of active rules a new rule specifying respective preferences, at least relatively, for at least some of the plurality of accesses by selecting, as the new rule, the active rule having the most preferred rule-based priority value; and

selecting an access for use by the mobile terminal based on the new rule.
