System and method for wireless mobility protocol for highly directional antennas with network topology awareness
View Patent ↗A system for communicating wireless signals between one or more sector controllers (SC) and one or more subscriber stations (SS) using different channels and different beams, wherein each of the one or more SS and the SC has a corresponding highly directional antenna; the one or more SC comprises a first SC; the one or more SS comprises a first SS; the first SS obtains network topology awareness (NTA) data from the first SC; the first SS selects a channel, a beam, and one of the one or more SC to establish an RF link based on the NTA data; and the first SS communicating with the selected SC using the established RF link.
1. A method performed by a subscriber station for selecting one of a plurality of sector controllers in a wireless communications network, the method comprising:
receiving a network topology data set from one of the plurality of sector controllers, the network topology data set comprising network settings corresponding to the plurality of sector controllers;
based on the settings, selecting one of the plurality of sector controllers; and
utilizing the settings to communicate with the selected one of the plurality of sector controllers;
wherein selecting one of the plurality of sector controllers further comprises utilizing GPS data associated with the subscriber station.
2. The method of claim 1 wherein the subscriber station periodically receives an updated plurality of network topology set.
3. The method of claim 2 wherein the subscribe station requests the periodically received updated of the network topology set.
4. The method of claim 3 wherein the subscribe station requests the periodically received updated of the network topology set when crossing a geo-fence.
5. The method of claim 3 wherein the subscribe station requests the periodically received updated of the network topology set when moving more than a predetermined distance from its initial position.
6. The method of claim 2 wherein the subscriber station periodically receives the updated network topology set pushed from a second one of the plurality of sector controllers.
7. The method of claim 1 wherein selecting one the plurality of sector controllers comprises utilizing the plurality of network topology sets to attempt to evaluate communications with each of the plurality of sector controllers based on a positioning, acquiring and tracking algorithm.
8. The method of claim 7 wherein the positioning, acquiring and tracking algorithm is executed continuously.
9. The method of claim 1 wherein selecting one the plurality of sector controllers comprises utilizing the plurality of network topology sets is based on an antenna type of the subscriber station.
10. A method performed by a sector controller for distributing network topology data in a wireless communications network, the method comprising:
preconfiguring the sector controller with a network topology data sets, ea the network topology data set comprising network settings corresponding to the sector controller and a plurality of other sector controllers;
in response to receiving a registration request from a subscriber station, determining that the subscriber station is not at a fixed location and transmitting the network topology data sets to the subscriber station;
based on the settings, the subscriber station selecting one of the plurality of sector controllers; and
utilizing the settings to establish an operating link with the subscriber station;
wherein selecting one of the plurality of sector controllers further comprises utilizing GPS data associated with the subscriber station.
11. The method of claim 10 wherein the sector controller periodically receives an updated network topology set.
12. The method of claim 11 wherein in response to an update response from the subscriber station, the sector controller transmits the updated network topology set to the subscriber station.
13. The method of claim 11 wherein the sector controller periodically pushes the updated network topology set to the subscriber station.
14. The method of claim 10 further comprising the sector controller detecting an oversubscription ratio being exceeded and instructing the sector controller to initiate a handover procedure to an alternate sector controller.
15. The method of claim 10 further comprising the sector controller detecting a loading factor being exceeded and instructing the sector controller to initiate a handover procedure to an alternate sector controller.
