Abstract

Techniques are described for managing QoS parameters of a bearer for which at least a portion of bearer data is served over a WLAN radio access technology. According to these techniques, a first device may identify a first set of one or more QoS parameters for serving a bearer over a wireless wide area network (WWAN). The first device may also determine a second set of one or more QoS parameters for serving the bearer over the WLAN based on an association between the first set of QoS parameters and the second set of one or more QoS parameters.

First claim

What is claimed is:

1. A method of wireless communication, comprising:
communicating, by a first wireless device, data over a first bearer configured over a wireless wide area network (WWAN);
identifying, at the first wireless device, a first set of one or more quality-of-service (QoS) parameters for serving the data over the first bearer, the first set of one or more QoS parameters satisfying a first QoS requirement for WWAN;
transmitting a connectivity request message to a second wireless device;
in response to the connectivity request message, receiving, from the second wireless device, a second set of one or more QoS parameters for serving at least a portion of the data over a second bearer configured over a wireless local area network (WLAN), the second set of one or more QoS parameters being determined at the second wireless device based on the connectivity request message and an association between the first set of one or more QoS parameters and the second set of one or more QoS parameters, and the second set of one or more QoS parameters satisfying a second QoS requirement for WLAN; and
communicating, by the first wireless device, at least the portion of the data over the second bearer configured over the WLAN using the determined second set of one or more QoS parameters.

2. The method of claim 1 , wherein determining the second set of one or more QoS parameters comprises:
mapping the first set of one or more QoS parameters to the second set of one or more QoS parameters.

3. The method of claim 2 , wherein the mapping comprises a static mapping configured according to the association between the first set of one or more QoS parameters and the second set of one or more QoS parameters.

4. The method of claim 2 , wherein the mapping comprises a semi-static mapping.

5. The method of claim 2 , wherein the mapping is based at least in part on an operations, administration and maintenance (OAM) configuration of the WWAN.

6. The method of claim 2 , wherein the mapping comprises:
receiving the second set of one or more QoS parameters from a server in an Open Mobile Alliance Device Management (OMA DM) message.

7. The method of claim 2 , wherein the mapping comprises:
retrieving the second set of one or more QoS parameters from a Universal Subscriber Identity Module (USIM).

8. The method of claim 2 , further comprising:
adjusting the mapping between the first set of one or more QoS parameters and the second set of one or more QoS parameters.

9. The method of claim 1 , further comprising:
transmitting the second set of one or more QoS parameters from the first wireless device to a second device in connection with establishing the second bearer.

10. The method of claim 9 , wherein the first bearer comprises an evolved packet system (EPS) bearer for a mobile device, the second device comprises the mobile device, and the second set of one or more QoS parameters is transmitted via a non-access stratum (NAS) layer of the WWAN.

11. The method of claim 9 , wherein the first bearer comprises an evolved packet system (EPS) bearer for a mobile device, the second device comprises the mobile device, and the second set of one or more QoS parameters is transmitted via a radio resource control (RRC) layer of the WWAN.

12. The method of claim 9 , wherein the first bearer comprises an evolved packet system (EPS) bearer, the first wireless device comprises a mobility management entity, the second device comprises an eNodeB, and the second set of one or more QoS parameters is transmitted over a S1 interface of the WWAN.

13. The method of claim 9 , wherein the first bearer comprises an evolved packet system (EPS) bearer and the second set of one or more QoS parameters is transmitted over a core network interface.

14. The method of claim 9 , wherein the first bearer comprises a radio bearer, the first wireless device comprises a serving general packet radio service support node, the second device comprises a radio network controller, and the second set of one or more QoS parameters is transmitted over an Iu interface of the WWAN.

15. The method of claim 1 , further comprising:
receiving the first set of one or more QoS parameters at the first wireless device in connection with establishing the first bearer.

16. The method of claim 15 , wherein the first bearer comprises an evolved packet system (EPS) bearer, the first wireless device comprises a user equipment (UE), and the first set of one or more QoS parameters comprises a QoS class identifier (QCI) that is received over a non-access stratum (NAS) layer.

17. The method of claim 15 , wherein the first bearer comprises a radio bearer, the first wireless device comprises a user equipment (UE), and the first set of one or more QoS parameters comprises a logical channel priority that is received over a radio resource control (RRC) layer.

18. The method of claim 1 , wherein the first wireless device comprises a user equipment (UE), the method further comprising:
transmitting a requested second set of QoS parameters to the WWAN in connection with one or more of a packet data network connectivity request message, an attach request message, a bearer resource allocation message, or a modify bearer context request message.

19. The method of claim 1 , wherein the first set of one or more QoS parameters comprises one or more of:
a QoS class identifier (QCI), an access class priority, a logical channel priority, a traffic class, or a traffic handling priority.

20. The method of claim 1 , wherein the second set of one or more QoS parameters comprise one or more of:
an access category (AC), a maximum buffer size, a bit rate, or a latency.

21. An apparatus for managing wireless communication, comprising:
at least one processor; and
a memory communicatively coupled with the at least one processor, wherein the at least one processor is configured to execute code stored on the memory to:
communicate, at a first wireless device, data over a first bearer configured over a wireless wide area network (WWAN);
identify, at the first wireless device, a first set of one or more quality-of-service (QoS) parameters for serving the data over the first bearer, the first set of one or more QoS parameters satisfying a first QoS requirement for WWAN;
transmit a connectivity request message to a second wireless device;
in response to the connectivity request message, receive, from Flail the second wireless device, a second set of one or more QoS parameters for serving at least a portion of the data over a second bearer configured over a wireless local area network (WLAN), the second set of one or more QoS parameters being determined at the second wireless device based on the connectivity request message and an association between the first set of one or more QoS parameters and the second set of one or more QoS parameters, and the second set of one or more QoS parameters satisfying a second QoS requirement for WLAN; and

22. The apparatus of claim 21 , wherein the at least one processor is further configured to determine the second set of one or more QoS parameters by:
mapping the first set of one or more QoS parameters to the second set of one or more QoS parameters.

23. The apparatus of claim 22 , wherein the mapping comprises a static mapping configur
