communication systems using wireless links for non-selective communication, e.g. wireless extensions H04M1/72) ## Abstract A method and apparatus for receiving access network selection information, and obtaining information about whether the received information complies with operator's access network selection policy. ## Claims ### Claim 1 A method comprising: receiving at a user equipment (UE's) home network access network selection information concerning a pending session the UE seeks to establish with an other network; determining whether the other network and/or the pending session complies with the home network's access network selection policy, and only if not the home network either: rejecting the pending session, or allowing the pending session with at least one of increased charges, reduced data rate and degraded quality. ### Claim 2 (depends on 1) The method of claim 1, wherein the access network information comprises information indicating at least one of a service and/or a service type requested by the UE for the pending session. ### Claim 3 (depends on 2) The method of claim 2, comprising: the determining comprises determining whether the requested service and/or service type complies with the home network access network selection policy. ### Claim 4 (depends on 1) The method of claim 1, comprising: receiving said home network access network selection information in response to asking. ### Claim 5 (depends on 1) The method of claim 1, wherein the determining comprises querying a policy repository. ### Claim 6 (depends on 1) The method of claim 1, comprising: sending towards user equipment an indication that the pending session is rejected or is allowed with at least one of the increased charges, reduced data rate and degraded quality. ### Claim 7 (depends on 1) The method of claim 1, comprising: performing policy enforcement concerning the pending session based on the determining. ### Claim 8 (depends on 1) The method of claim 1, wherein the home network access network selection information comprises location information corresponding to the UE. ### Claim 9 (depends on 8) The method of claim 8, comprising: performing location-dependent policy enforcement concerning the pending session based on the determining. ### Claim 10 (depends on 1) The method of claim 1, comprising: having access networks in a priority list, and accepting, modifying or rejecting the pending session based on priority of the other network within the priority list. ### Claim 11 An apparatus comprising: a communication interface configured to receive a user equipment (UE's) home network access network selection information concerning a pending session the UE seeks to establish with an other network; a first processor configured with a memory storing program code that when executed causes the apparatus to determine whether the other network and/or the pending session complies with the home network's access network selection policy and only if not either: reject the pending session, or allow the pending session with at least one of increased charges, reduced data rate and degraded quality. ### Claim 12 (depends on 11) The apparatus of claim 11, wherein the access network information comprises information indicating at least one of a service and/or a service type requested by the UE for the pending session. ### Claim 13 (depends on 12) The apparatus of claim 12, wherein the apparatus is configured to determine whether the requested service and/or service type complies with the home network access network selection policy. ### Claim 14 (depends on 11) The apparatus of claim 11, wherein the apparatus is configured to receive said home network access network selection information in response to asking. ### Claim 15 (depends on 11) The apparatus of claim 11, wherein the apparatus is configured to determine as said by querying a policy repository. ### Claim 16 (depends on 11) The apparatus of claim 11, wherein the apparatus is configured to send the UE an indication that the pending session is rejected or is allowed with at least one of the increased charges, reduced data rate and degraded quality. ### Claim 17 (depends on 11) The apparatus of claim 11, wherein the apparatus is configured to perform policy enforcement concerning the pending session based on the determination. ### Claim 18 An apparatus comprising: a communication interface configured to receive compliance information indicating that a pending session a user equipment (UE) seeks to establish with an other network, and/or the other network, does not comply with a network selection access policy of the UE's home network; and a user interface configured to display in response an indication that the pending session is either rejected, or the pending session is allowed with at least one of increased charges, reduced data rate and degraded quality. ### Claim 19 (depends on 18) The apparatus according to claim 18, wherein the UE comprises the apparatus.
