Abstract

A method and an information handling system configured to select a mobility anchor point for a mobile device in a distributed mobility anchor point network may comprise collecting information about movement behavior or data transfer behavior of the mobile device, or tunneling overhead of two or more base stations. A mobility anchor point associated with a first base station may be assigned to the mobile device if the mobile device is connected to the first base station for at least a predetermined amount of time, if the mobile device transfers at least a predetermined amount of data via the first base station, or device if a tunneling overhead of the first base station is less than a predetermined level. In some embodiments, a centralized mobility anchor may be assigned to the mobile device if the mobile device is highly mobile and there is no identified base station to which the mobile device is frequently connected.

Claims

1. An information handling system, comprising:

a processor; and

a memory coupled to the processor, wherein instructions in the memory configure the processor to select a mobility anchor point for a mobile device in a distributed mobility anchor point network, the processor being configured to;

collect information about data transfer behavior of a mobile device in the network; and

assign a mobility anchor point associated with a first base station to the mobile device if the mobile device transfers at least a predetermined amount of data via the first base station.

2. An information handling system as claimed in claim 1, wherein the mobility anchor point associated with the first base station is assigned to the mobile device even if the mobile device initially connects to the network via another base station different than the first base station.

3. An information handling system as claimed in claim 1, wherein the processor is further configured to assign a mobility anchor point associated with an initial base station via which the mobile device initially connects to the network in the event the mobile device does transfer at least the predetermined amount of data via the first base station.

4. An information handling system as claimed in claim 1, wherein the mobility anchor point associated with the first base station is collocated with the first base station.

5. An information handling system as claimed in claim 1, wherein the mobility anchor point associated with the first base station is collocated with an access router that connects the first base station to the network.

6. An article of manufacture comprising a non-transitory storage medium having instructions stored thereon that, if executed by a processor, result in:

collecting information about data transfer behavior of a mobile device in a distributed mobility anchor point network; and

assigning a mobility anchor point associated with a first base station to the mobile device if the mobile device transfers at least a predetermined amount of data via the first base station.

7. An article of manufacture as claimed in claim 6, wherein the mobility anchor point associated with the first base station is assigned to the mobile device even if the mobile device initially connects to the network via another base station different than the first base station.

8. An article of manufacture as claimed in claim 6, wherein the instructions, if executed, further result in assigning a mobility anchor point associated with an initial base station via which the mobile device initially connects to the network in the event the mobile device does transfer at least the predetermined amount of data via the first base station.

9. An article of manufacture as claimed in claim 6, wherein the mobility anchor point associated with the first base station is collocated with the first base station.

10. An article of manufacture as claimed in claim 6, wherein the mobility anchor point associated with the first base station is collocated with an access router that connects the first base station to the network.

11. A method to select a mobility anchor point for a mobile device in a distributed mobility anchor point network, comprising:

collecting information about data transfer behavior of the mobile device in the distributed mobility anchor point network; and

assigning a mobility anchor point associated with a first base station to the mobile device if the mobile device transfers at least a predetermined amount of data via the first base station.

12. A method as claimed in claim 11, wherein the mobility anchor point associated with the first base station is assigned to the mobile device even if the mobile device initially connects to the network via another base station different than the first base station.

13. A method as claimed in claim 11, further comprising assigning a mobility anchor point associated with an initial base station via which the mobile device initially connects to the network in the event the mobile device does transfer at least the predetermined amount of data via the first base station.

14. A method as claimed in claim 11, wherein the mobility anchor point associated with the first base station is collocated with the first base station.

15. A method as claimed in claim 11, wherein the mobility anchor point associated with the first base station is collocated with an access router that connects the first base station to the network.
