Abstract

One aspect of the present invention is to provide a Connectivity Management (CM) function for use in networks such as a wireless network. The CM function can support both User Equipment (UE) and Machine Type Communication (MTC) devices in the network. In one embodiment of the first aspect, there is provided methods and systems for CM for a plurality of different types of devices that may evaluate tracking criteria to determine where and when wireless resources will need to be allocated to a wireless device. In some embodiments, these tracking criteria include location tracking and/or activity tracking. Another aspect provides for the instantiation of virtual CM functions established at appropriate physical nodes to provide device specific or service specific CM.

Claims

1. A method of connectivity management (CM) for use in a wireless network, the method comprising:

selecting a network connectivity management policy for a service in the wireless network in accordance with characteristics of the service including device capability, and location predictability associated with devices supported by the service; and

transmitting an instruction to a network connectivity management function associated with the service, the instruction indicating the selected network connectivity management policy.

2. The method of claim 1 further including the step of receiving the characteristics of the service from a customer.

3. The method of claim 1 wherein the device capability includes information about the radio interfaces supported by devices supported by the service.

4. The method of claim 1 wherein the step of selecting is performed in accordance with an activity profile associated with the service.

5. The method of claim 1 wherein the location predictability indicates a degree of location predictability including a fixed position, predictable within a range and unpredictable.

6. The method of claim 1 wherein the step of selecting is performed by selecting a policy profile from a set of predefined policies in accordance with an activity profile and location predictability profile associated with the service.

7. The method of claim 6 wherein the activity profile indicates an activity status including one of active, idle and predicted to be active states.

8. The method of claim 7 wherein the predicted to be active state indicates when the device is predicted to be active.

9. The method of claim 6 wherein the activity profile and location predictability profile are received from a customer.

10. The method of claim 1 further including transmitting an instruction to instantiate the network connectivity management function on a computing platform in the wireless network.

11. The method of claim 1 further including selecting the network connectivity management function from a set of connectivity management functions in accordance with the selected policy.

12. The method of claim 1 further including the steps of:

re-selecting a network connectivity management policy in accordance with location predictability and activity tracking information obtained through monitoring the service; and

transmitting an instruction to the connectivity management function associated with the service, indicating the re-selected network connectivity management policy.

13. A connectivity manager, for use in a wireless network, comprising:

a network interface for communicating with other nodes in the wireless network;

a non-transitory memory for storing instructions; and

a processor for executing the stored instructions, that upon executing the instructions causes the connectivity manager to;

select a network connectivity management policy for a service in the wireless network in accordance with characteristics of the service including device capability, and location predictability associated with devices supported by the service; and

transmit, over the network interface, an instruction to a connectivity management function associated with the service, the instruction indicating the selected network connectivity management policy.

14. The connectivity manager of claim 13 wherein the processor is further configured to perform the selecting and transmitting in response to receipt of the characteristics of the service from a customer.

15. The connectivity manager of claim 13 wherein the device capability includes information about the radio interfaces supported by devices supported by the service.

16. The connectivity manager of claim 13 wherein the processor is further configured to select the network connectivity management profile in accordance with an activity profile associated with the service.

17. The connectivity manager of claim 13 wherein the location predictability indicates a degree of location predictability including a fixed position, predictable within a range and unpredictable.

18. The connectivity manager of claim 13 wherein the processor is further configured to select the network connectivity management profile by selecting a policy profile from a set of predefined policies in accordance with an activity profile and location predictability profile associated with the service.

19. The connectivity manager of claim 18 wherein the activity profile indicates an activity status including one of active, idle and predicted to be active states.

20. The connectivity manager of claim 19 wherein the predicted to be active state indicates when the device is predicted to be active.

21. The connectivity manager of claim 18 wherein the activity profile and location predictability profile are received from a customer.

22. The connectivity manager of claim 13 wherein the processor is further configured to cause the connectivity manager to transmit, over the network interface, an instruction to instantiate the network connectivity management function on a computing platform in the wireless network.

23. The connectivity manager of claim 13 wherein the processor is further configured to cause the connectivity manager to select the network connectivity management function, from a set of network connectivity management functions in the network, in accordance with the selected policy.

24. The connectivity manager of claim 13 wherein the processor is further configured to cause the connectivity manager to:

re-select a network connectivity management policy in accordance with location predictability and activity tracking information obtained through monitoring the service; and

transmit, over the network interface, an instruction to the network connectivity management function associated with the service, indicating the re-selected network connectivity management policy.
