Abstract

Certain aspects of the present disclosure relate to methods and apparatus for wireless communication, and more particularly, to methods and apparatus to enable a node to be aware of active services and context for a mobile device in order to determine the load balancing and admission control for the services. For example, in certain aspects, a mobile device for managing at least one data flow between a core network and the mobile device may determine whether at least one of the data flow or a service related to the data flow should be reported and send a report to a first node based on the determination. The report may identify at least one of the data flow or service and indicates a packet data network (PDN) connection or bearer associated with the service or data flow.

Claims

1. A method of wireless communication by a second node for managing a data flow, comprising:

receiving an indication of one or more service requirements of the data flow that is active for a bearer or a packet data network (PDN) connection;

deciding, based on the one or more service requirements of the data flow, whether to serve the data flow at the second node or a first node; and

sending, to the first node, a request for admission of the data flow based on the decision, wherein the request for admission comprises an indication of a protocol layer for aggregation of the data flow.

2. The method of claim 1, wherein the first node and the second node operate using different radio access technologies (RATs).

3. The method of claim 1, wherein the data flow comprises a new data flow.

4. The method of claim 1, further comprising transmitting a configuration which indicates which data flows to report.

5. The method of claim 1, wherein the data flow comprises data for an application.

6. The method of claim 1, wherein the data flow comprises data for a service.

7. A second node for managing a data flow, comprising:

means for receiving an indication of one or more service requirements of the data flow that is active for a bearer or a packet data network (PDN) connection;

means for deciding, based on the one or more service requirements of the data flow, whether to serve the data flow at the second node or a first node; and

means for sending, to the first node, a request for admission of the data flow based on the decision, wherein the request for admission comprises an indication of a protocol layer for aggregation of the data flow.

8. The second node of claim 7, wherein the first node and the second node operate using different radio access technologies (RATs).

9. The second node of claim 7, wherein the data flow comprises a new data flow.

10. The second node of claim 7, further comprising means for transmitting a configuration which indicates which data flows to report.

11. The second node of claim 7, wherein the data flow comprises data for an application.

12. The second node of claim 7, wherein the data flow comprises data for a service.

13. A non-transitory computer-readable medium for managing a data flow having instructions stored thereon, to be executed by a processor, for causing a second node to:

receive an indication of one or more service requirements of the data flow that is active for a bearer or a packet data network (PDN) connection;

decide, based on the one or more service requirements of the data flow, whether to serve the data flow at the second node or a first node; and

send, to the first node, a request for admission of the data flow based on the decision, wherein the request for admission comprises an indication of a protocol layer for aggregation of the data flow.
