Supporting multiple concurrent service contexts with a single connectivity context
Methods and apparatus supporting multiple concurrent service contexts sharing a single connectivity context are disclosed. A device may initiate a radio link with a network node and establish a connectivity context with the network node over the radio link using a connectivity logical context of the device. The network node may receive, authenticate, and authorize context establishment requests. A first service context with a first service management entity may be established over the radio link using a first logical context of the device, where the first logical context is distinct from the connectivity logical context. Multiple service connections using multiple service contexts based on multiple logical contexts of the device may share the connectivity context and may be established over the radio link.
1. A method operational at a device comprising:
initiating a radio link between the device and a network node;
establishing a connectivity context with a connectivity serving node; and
establishing a plurality of service contexts with a service management entity,
wherein the connectivity context and the plurality of service contexts are all established over the radio link.
2. The method of claim 1 , wherein a connectivity logical context of the device is used to establish the connectivity context with the connectivity serving node.
3. The method of claim 2 , wherein the connectivity context is based on a first set of credentials associated with the connectivity logical context of the device.
4. The method of claim 1 , wherein a plurality of logical contexts of the device are used to establish the plurality of service contexts, respectively, with the service management entity.
5. The method of claim 4 , wherein each of the plurality of service contexts is based a corresponding set of credentials associated with a corresponding one of the plurality of logical contexts of the device.
6. The method of claim 1 , wherein the connectivity context is shared by the plurality of service contexts.
7. The method of claim 1 , wherein the connectivity context includes mobility management and signaling security for the device.
8. The method of claim 1 , wherein the plurality of service contexts each switch between at least a connected mode and a disconnected mode, and each of the plurality of service contexts is maintained in the device regardless of whether a given service context of the plurality of service contexts switches between the connected mode and the disconnected mode.
9. The method of claim 1 , wherein when there is no connection between the device and the network node with respect to at least one of the plurality of service contexts, the at least one of the plurality of service contexts does not have to be reestablished when a connection is reestablished between the device and the network node with respect to the at least one of the plurality of service contexts.
10. The method of claim 9 , wherein the connection is reestablished between the device and the network node when the at least one of the plurality of service contexts switches from a disconnected mode to a connected mode.
11. A device, comprising:
a network communication circuit for communicating over a wireless network; and
a processing circuit coupled to the network communication circuit, the processing circuit configured to:
initiate a radio link between the device and a network node;
establish a connectivity context with a connectivity serving node; and
establish a plurality of service contexts with a service management entity,
wherein the connectivity context and the plurality of service contexts are all established over the radio link.
12. The device of claim 11 , wherein the processing circuit is further configured to:
establish the connectivity context with the connectivity serving node using a connectivity logical context of the device.
13. The device of claim 12 , wherein the connectivity context is based on a first set of credentials associated with the connectivity logical context of the device.
14. The device of claim 11 , wherein the processing circuit is further configured to:
establish the plurality of service contexts with the service management entity using a respective plurality of logical contexts of the device.
15. The device of claim 14 , wherein each of the plurality of service contexts is based a corresponding set of credentials associated with a corresponding one of the plurality of logical contexts of the device.
16. The device of claim 11 , wherein the processing circuit is further configured to:
share the connectivity context with the plurality of service contexts.
17. The device of claim 11 , wherein the connectivity context includes mobility management and signaling security for the device.
18. The device of claim 11 , wherein the processing circuit is further configured to:
maintain each of the plurality of service contexts regardless of whether a given service context of the plurality of service contexts switches between a connected mode and a disconnected mode.
19. The device of claim 11 , wherein when there is no connection between the device and the network node with respect to at least one of the plurality of service contexts, the at least one of the plurality of service contexts does not have to be reestablished when a connection is reestablished between the device and the network node with respect to the at least one of the plurality of service contexts.
20. The device of claim 19 , wherein the connection is reestablished between the device and the network node when the at least one of the plurality of service contexts switches from a disconnected mode to a connected mode.
