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 movement 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 is connected to the first base station for at least a predetermined amount of time.

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 mobile device does not connect to the first base station for a at least the predetermined amount of time.

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 coupled with the first base station.

6. 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.

7. An information handling system 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 information handling system as claimed in claim 6, 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.

9. An information handling system 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 information handling system 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. 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 tunneling overhead of two or more base stations of the network; and

assign a mobility anchor point associated with a first base station to the mobile device if a tunneling overhead of the first base station is less than a predetermined level.

12. An information handling system 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. An information handling system as claimed in claim 11, the processor being 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 tunneling overhead of the first base station is not less than a predetermined level.

14. An information handling system as claimed in claim 11, wherein the processor is further configured to otherwise assign a mobility anchor point associated with a second base station to the mobile device if a tunneling overhead of the second base station is lower than the tunneling overhead of 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 the first base station.

16. 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.

17. 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 movement behavior of a mobile device in the network;

if the mobile device is not mobile for at least a predetermined amount of time, assign a mobility anchor point associated with any base station via which the mobile device connects to the network; and

if the mobile device is mobile for at least the predetermined amount of time, assign a mobility anchor point associated with an identified base station via which the mobile device connects to the network with at least a predetermined frequency.

18. An information handling system as claimed in claim 17, wherein the processor is further configured to:

if the mobile device is mobile for at least the predetermined amount of time, but there is no identified base station via which the mobile device connects to the network with at least the predetermined frequency, assign a centralized mobility anchor point to the mobile device.

19. An information handling system as claimed in claim 17, wherein the processor is further configured to, if the mobile device is mobile for at least the predetermined amount of time, but there is no identified base station via which the mobile device connects to the network with at least the predetermined frequency, assign to the mobile device a mobility anchor point associated with a base station having a tunneling load below a predetermined amount of tunneling.

20. An information handling system as claimed in claim 17, wherein the processor is further configured to, if the mobile device connects to the network via a new base station having associated with a different mobility anchor point, create a tunnel between a base station associated with the assigned mobility anchor point and the new base station.
