Abstract

Various communication systems may benefit from coordination in interworking. For example, certain wireless communication systems may benefit from link setup level coordination, such as coordination between a first radio access technology base station and a terminal that is setting up a link to a second radio access technology. A method may include, for example, determining an allowed link setup level for a terminal. The method may also include communicating the allowed link setup level to the terminal.

Claims (47)

1. A method, comprising:

receiving, at a terminal, a minimum link setup level and a maximum link setup level; and

performing, by the terminal, link setup within a range defined by the minimum link setup level and the maximum link setup level,

wherein the minimum link setup level defines one or more operations that the terminal needs to execute successfully before the terminal is allowed to report a network or a radio access technology as available to a base station that communicated the minimum link setup level and the maximum link setup level to the terminal,

wherein the maximum link setup level defines one or more operations that the terminal is allowed to execute before reporting a network or a radio access technology as available to the base station, and

wherein the minimum link setup level and the maximum link setup level are different.

2. The method of claim 1 , further comprising:

sending, to the base station, a link setup level that the terminal has established with an access point on the terminal's own initiative.

3. The method of claim 1 , further comprising:

reporting regarding availability of the network or the radio access technology when the terminal has executed each of the one or more operations as defined by the minimum link setup level.

4. An apparatus, comprising:

at least one processor; and

at least one memory including computer program code,

wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to:

determine a minimum link setup level and a maximum link setup level for a terminal; and

communicate the minimum link setup level and the maximum link setup level to the terminal,

wherein the minimum link setup level defines one or more operations that the terminal needs to execute successfully before the terminal is allowed to report a network or a radio access technology as available to a base station that communicated the minimum link setup level and the maximum link setup level to the terminal,

wherein the maximum link setup level defines one or more operations that the terminal is allowed to execute before reporting a network or a radio access technology as available to the base station, and

wherein the minimum link setup level and the maximum link setup level are different.

5. The apparatus of claim 4 , wherein the at least one memory and the computer program code are configured to, with the at least one processor cause the apparatus at least to set an expected link setup level that the terminal is expected to reach in order to report availability of a second network or a second radio access technology for further proceeding of the offload process by the base station.

6. The apparatus of claim 4 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to provide, by an access network discovery and selection function management object, radio interworking steps to a wireless local area network terminal connected with the minimum link setup level and the maximum link setup level.

7. The apparatus of claim 4 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to receive from the terminal a link setup level that the terminal has established with an access point on the terminal's own initiative.

8. The apparatus of claim 4 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to receive a report from the terminal regarding availability of the network or the radio access technology when the terminal has executed the one or more operations as defined by the minimum link setup level.

9. The apparatus of claim 4 , wherein the base station is configured to command the terminal to use the network or the radio access technology without additional signaling of permission when the minimum link setup level is set to the highest data transmission level.

10. The apparatus of claim 4 , wherein one of the minimum link setup level and the maximum link setup level are communicated as an indication of a difference between the minimum link setup level and the maximum link setup level.

11. An apparatus, comprising:

at least one processor; and

at least one memory including computer program code,

wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to:

receive, at a terminal, a minimum link setup level and a maximum link setup level; and

perform, by the terminal, link setup within a range defined by the minimum link setup level and the maximum link setup level,

wherein the minimum link setup level defines tone or more operations that the terminal needs to execute successfully before the terminal is allowed to report a network or a radio access technology as available to a base station that communicated the minimum link setup level and the maximum link setup level to the terminal,

wherein the maximum link setup level defines one or more operations that the terminal is allowed to execute before reporting a network or a radio access technology as available to the base station, and

wherein the minimum link setup level and the maximum link setup level are different.

12. The apparatus of claim 11 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to send, to the base station, a link setup level that the terminal has established with an access point on the terminal's own initiative.

13. The apparatus of claim 11 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to report regarding availability of the network or the radio access technology when the terminal has executed the one or more operations as defined by the minimum link setup level.

14. The apparatus of claim 11 , wherein the link setup is configured to provide data offloading of the terminal from a first radio access technology to a second radio access technology.

15. The method of claim 1 , further comprising:

receiving a signal from the base station configured to allow additional operations of the terminal; and

performing the additional operations upon receiving the signal.

16. The method of claim 1 , wherein the link setup is configured to provide data offloading of the terminal from a first radio access technology to a second radio access technology.

17. The apparatus of claim 4 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to allow, by the base station, additional operations of the terminal by transmitting a signal to the terminal.

18. The apparatus of claim 4 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to coordinate, with the base station, operations of a wireless local area network terminal connected with the minimum link setup level and the maximum link setup level.

19. The apparatus of claim 11 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to:

receive a signal from the base station configured to allow additional operations of the terminal; and

perform the additional operations upon receiving the signal.

20. The apparatus of claim 4 , wherein the link setup is configured to provide data offloading of the terminal from a first radio access technology to a second radio access technology.
