Abstract

A mobile node registers with a wireless telecommunications network to obtain a mobile node registration having a registration time period. Before the registration time period expires, the mobile node'"'"'s registration is renewed, if a renewal criterion is met. The renewal criterion distinguishes between user data traffic and automatic data traffic.

Claims

1. A method of registration management for a mobile node, said method comprising:

registering said mobile node with a wireless telecommunications network to obtain a mobile node registration, said mobile node registration having a registration time period;

said mobile node transmitting and receiving packet data traffic within said registration time period, said packet data traffic including user data traffic and/or automatic data traffic;

determining whether a renewal criterion is met, wherein determining whether said renewal criterion is met comprises determining how much of said packet data traffic occurs during a sampling window within said registration time period, said sampling window being exclusive of a predictable time period that is used by said mobile node to transmit automatic data traffic, wherein said renewal criterion is met if at least a predetermined amount of said packet data traffic occurs during said sampling window, such that renewal is based on a presence of user data traffic in said packet data traffic; and

renewing said mobile node registration if said renewal criterion is met.

2. The method of claim 1, wherein renewing said mobile node registration comprises:

re-registering said mobile node with said wireless telecommunications network.

3. The method of claim 1, wherein renewing said mobile node registration occurs during said registration time period.

4. The method of claim 1, wherein said mobile node determines whether said renewal criterion is met.

5. The method of claim 1, wherein said wireless telecommunications network determines whether said renewal criterion is met.

6. The method of claim 5, further comprising:

providing said renewal criterion based on a customer profile.

7. A method of resource management for a mobile node in communication with a wireless telecommunications network, said method comprising:

allocating a resource of said wireless telecommunications network to said mobile node for a resource allocation time period;

said mobile node transmitting and receiving packet data traffic within said resource allocation time period, said packet data traffic including user data traffic and/or automatic data traffic;

determining whether a renewal criterion is met, wherein determining whether said renewal criterion is met comprises determining how much of said packet data traffic occurs during a sampling window within said resource allocation time period, said sampling window being exclusive of a predictable time period that is used by said mobile node to transmit automatic data traffic, wherein said renewal criterion is met if at least a predetermined amount of said packet data traffic occurs during said sampling window, such that renewal is based on a presence of user data traffic in said packet data traffic; and

re-allocating said resource to said mobile node if said renewal criterion is met.

8. The method of claim 7, wherein said resource is a dynamically assigned internet protocol (IP) address.

9. The method of claim 7, further comprising:

providing said renewal criterion based on a customer profile.

10. A method of registration management for a mobile node, said method comprising:

registering said mobile node with a wireless telecommunications network to obtain a mobile node registration, said mobile node registration having a registration time period;

said mobile node transmitting and receiving packet data traffic within said registration time period, said packet data traffic including user data traffic and/or automatic data traffic, wherein a predictable amount of automatic data traffic occurs during said registration time period;

determining whether a renewal criterion is met, wherein determining whether said renewal criterion is met comprises determining how much of said packet data traffic occurs during a sampling window within said registration time period, and wherein said renewal criterion is met if at least a cutoff amount of said packet data traffic occurs during said sample window, said cutoff amount being greater than said predictable amount, such that renewal is based on a presence of user data traffic in said packet data traffic; and

renewing said mobile node registration if said renewal criterion is met.

11. The method of claim 10, wherein renewing said mobile node registration comprises:

re-registering said mobile node with said wireless telecommunications network.

12. The method of claim 10, wherein renewing said mobile node registration occurs during said registration time period.

13. The method of claim 10, wherein said mobile node determines whether said renewal criterion is met.

14. The method of claim 10, wherein said wireless telecommunications network determines whether said renewal criterion is met.

15. The method of claim 14, further comprising:

providing said renewal criterion based on a customer profile.

16. A method of resource management for a mobile node in communication with a wireless telecommunications network, said method comprising:

allocating a resource of said wireless telecommunications network to said mobile node for a resource allocation time period;

said mobile node transmitting and receiving packet data traffic within said resource allocation time period, said packet data traffic including user data traffic and/or automatic data traffic, wherein a predictable amount of automatic data traffic occurs during said resource allocation time period;

determining whether a renewal criterion is met, wherein determining whether said renewal criterion is met comprises determining how much of said packet data traffic occurs during a sampling window within said resource allocation time period, and wherein said renewal criterion is met if at least a cutoff amount of said packet data traffic occurs during said sample window, said cutoff amount being greater than said predictable amount, such that renewal is based on a presence of user data traffic in said packet data traffic; and

re-allocating said resource to said mobile node if said renewal criterion is met.

17. The method of claim 16, wherein said resource is a dynamically assigned internet protocol (IP) address.

18. The method of claim 16, further comprising:

providing said renewal criterion based on a customer profile.
