Abstract

Method and apparatus relating to determining the services exempted from being blocked when accessing a communication system based on the one or more access network of different technology type supported by a wireless device are provided. The method is performed at the wireless device that supports more than one access network technology type (3GPP, non-3GPP) and comprises obtaining on a per access network technology type, one or more list of services exempted from being blocked when accessing the system using a particular access network type and providing to the communication system over each access network used by the wireless device, information indicating an activity status related to exempting services from being blocked in accordance with the technology type of each of the supported access network.

First claim

The invention claimed is:

1. A wireless device, comprising:
one or more transceivers; and
circuitry connected to the one or more transceiver, the circuitry operable to cause the wireless device to
provide, to a network node, information indicating an activity status related to exempting services from being blocked for each of a 3GPP and a non-3GPP access network used by the wireless device; and
obtain one or more list of services exempted from being blocked for the at least one of the 3GPP and the non-3GPP access network.

2. A method of operation of a user plane network entity in a communication system of enforcing services for a wireless device, the method comprising:
obtaining for each 3GPP and non-3GPP access network type used by the wireless device, at least one list of services exempted from being blocked;
receiving downlink traffic for the wireless device;
determining whether the downlink traffic is to be transmitted over the 3GPP or the non-3GPP access network type used by the wireless device;
upon determining that the downlink traffic corresponds to a service exempted from being blocked for the determined access network type according to the obtained list of services for the determined access network type, transmitting the traffic to the wireless device over the determined access network type; and
upon determining that the downlink traffic corresponds to a service that is not exempted from being blocked for the determined access network type, blocking the traffic from being transmitted to the wireless device over the determined access network type.

3. The method of claim 2 , wherein said obtaining for each of the 3GPP and non-3GPP access network type at least one list of services exempted from being blocked further comprises obtaining on a per access network type a list of services exempted from being blocked in the Home Public Land Mobile Network, HPLMN and a list of services exempted from being blocked in a Visited PLMN, VPLMN.

4. The wireless device of claim 1 , wherein the circuitry is further operable to cause the wireless device to obtain at initial attach procedure or packet data session establishment procedure the one or more list of services exempted from being blocked per access network type.

5. The method of claim 2 wherein said determining that the downlink traffic corresponds to a service further comprises detecting at least one of a service data flow or a service type corresponding to a service by applying configured traffic filters.

6. A method of operation of a control network entity in a communication system of controlling use of services, the method comprising:
obtaining from a wireless device that is simultaneously connected over a 3GPP and a non-3GPP access network, an indication of a status in exempting services from being blocked for each of the 3GPP and non-3GPP access network used by the wireless device; and
sending to the wireless device, information indicating support of exempting services from being blocked in the communication system for each of the 3GPP and non-3GPP access networks used by the wireless device.

7. The method of claim 6 further comprising providing for each of the 3GPP and non-3GPP access network used by the wireless device, at least one list of services exempted from being blocked for the wireless device.

8. The method of claim 7 wherein the at least one list of services exempted from being blocked further comprises a list of services exempted from being blocked in the Home Public Land Mobile Network, HPLMN, and a list of services exempted from being blocked in a Visited PLMN, VPLMN.

9. The wireless device of claim 1 , wherein the information indicating the activity status corresponds to an indication of whether the wireless device has enabled or disabled a capability to exempt services from being blocked over each of the 3GPP and non-3GPP access network.

10. The wireless device of claim 1 wherein the one or more list of exempted services for the at least one of the 3GPP and the non-3GPP access network comprises a list of services exempted from being blocked that is applied when the wireless device is connected to the communication system in a Home Public Land Mobile Network, HPLMN.

11. The wireless device of claim 1 wherein the one or more list of exempted services for the at least one of the 3GPP and the non-3GPP access network comprises a list of services exempted from being blocked to be applied when the wireless device is connected to the communication system in a Visited Public Land Mobile Network, VPLMN.

12. The wireless device of claim 11 , wherein the wireless device is simultaneously connected to the HPLMN over one of the 3GPP or the non-3GPP access network and to a VPLMN over the other one of the 3GPP or the non-3GPP access network.

13. The wireless device of claim 1 wherein the non-3GPP access network is a Wireless Lan Network, WLAN.
