1. A method comprising:
- a first base station among a plurality of base stations in a wireless wide area network (WWAN) determining that a level of load in a wireless coverage area exceeds a load threshold; and
responsive to determining that the level of load exceeds the load threshold, the first base station (i) obtaining a first keycode from a keycode library, wherein the first keycode then becomes unavailable to the other base stations of the plurality of base stations, (ii) identifying a carrier frequency, and (iii) using the first keycode to activate the identified carrier frequency in the wireless coverage area;
wherein the first keycode corresponds to a license for a given base station to activate an additional frequency;
the first base station determining whether a neighboring base station in the plurality of base stations is currently using a second keycode from the keycode library to provide service on a particular carrier frequency; and
responsive to determining that the neighboring base station is currently using a second keycode from the keycode library to provide service on the particular carrier frequency, the first base station updating a neighbor-list message for the first base station to reflect the neighboring base station providing service on the particular carrier frequency.

Abstract
Methods and systems are provided for dynamic allocation of carrier frequencies in wireless wide area networks (WWANs). A first base station among a plurality of base stations in a WWAN determines that a level of load in a wireless coverage area exceeds a load threshold, and responsively (i) obtains a first keycode from a keycode library, wherein the first keycode then becomes unavailable to the other base stations of the plurality of base stations, (ii) identifies a carrier frequency, and (iii) uses the first keycode to activate the identified carrier frequency in the wireless coverage area.

12. A base station among a plurality of base stations in a wireless wide area network (WWAN), the base station comprising:
-
a base transceiver station (BTS), wherein the BTS provides a wireless coverage area; a mobile switching center (MSC) interface; a packet data serving node (PDSN) interface; a processor; and data storage having stored therein instructions executable by the processor to; determine that a level of load in the wireless coverage area exceeds a load threshold; and responsive to determining that the level of load exceeds the load threshold, (i) obtain a first keycode from a keycode library, wherein the first keycode then becomes unavailable to the other base stations of the plurality of base stations, (ii) identify a carrier frequency, and (iii) use the first keycode to activate the identified carrier frequency in the wireless coverage area;
wherein the first keycode corresponds to a license for a given base station to activate an additional frequency;
the base station determining whether a neighboring base station in the plurality of base stations is currently using a second keycode from the keycode library to provide service on a particular carrier frequency; and
responsive to determining that the neighboring base station is currently using a second keycode from the keycode library to provide service on the particular carrier frequency, the first base station updating a neighbor-list message for the first base station to reflect the neighboring base station providing service on the particular carrier frequency. - View Dependent Claims (13, 14)

15. A method comprising:
-
maintaining a keycode library comprising a plurality of keycodes, wherein each keycode of the plurality of keycodes comprises data for a given base station among a plurality of base stations in a wireless wide area network (WWAN) to use in activating a carrier frequency in a given wireless coverage area; the keycode library receiving a request for a keycode from a first base station in the plurality of base stations; and responsive to receiving the request, the keycode library (i) transmitting a response to the first base station, wherein the response provides a first keycode from the plurality of keycodes, and (ii) making the first keycode unavailable to other base stations of the plurality of base stations;
wherein each keycode corresponds to a license for a given base station to activate an additional frequency;
the first base station determining whether a neighboring base station in the plurality of base stations is currently using a second keycode from the keycode library to provide service on a particular carrier frequency; and
responsive to determining that the neighboring base station is currently using a second keycode from the keycode library to provide service on the particular carrier frequency, the first base station updating a neighbor-list message for the first base station to reflect the neighboring base station providing service on the particular carrier frequency. - View Dependent Claims (16, 17, 18)
