Abstract

Efficient paging operation for femtocell deployment is generally presented. In this regard, a paging controller is introduced including a wired backbone interface to communicate with a plurality of macro base stations and a plurality of femto base stations, and control logic, the control logic to generate a page for a mobile station, and the control logic to transmit the page over the wired backbone interface to a select subset of all base stations, wherein the select subset of all base stations includes base stations that the mobile station is authorized to access. Other embodiments are also described and claimed.

Claims

1. A broadband wireless network paging controller comprising:

a wired backbone interface to communicate with a plurality of macro base stations and a plurality of femto base stations; and

control logic to generate a page for a mobile station and transmit the page over the wired backbone interface to a select subset of all base stations, the select subset of all base stations including base stations that the mobile station is authorized to access, the control logic to select the select subset by accessing a database listing base stations that the mobile station is authorized to access, the control logic to communicate with base stations to maintain the database, the control logic to periodically query the femto base stations about subscriber group changes.

2. The broadband wireless network paging controller of claim 1, further comprising the control logic to transmit the page over the wired backbone interface to femto base stations sharing a same paging group identification (PGID).

3. The broadband wireless network of claim 1, wherein the select subset includes all macro base stations with paging group ID(s) corresponding to the page.

4. A broadband wireless network comprising:

a plurality of macro base stations;

a plurality of femto base stations;

a mobile station;

a wired backbone; and

a paging controller, the paging controller to generate a page for the mobile station and to transmit the page over the wired backbone to a select subset of all base stations, wherein the select subset of all base stations includes base stations that the mobile station is authorized to access, the paging controller to select the select subset by accessing a database listing base stations that the mobile station is authorized to access, the paging controller to communicate with base stations to maintain the database, and the paging controller to periodically query the femto base stations about subscriber group changes.

5. The broadband wireless network of claim 4, further comprising the paging controller to receive updates from the femto base stations about subscriber group changes and to update the database.

6. The broadband wireless network of claim 4, further comprising the paging controller to transmit the page over the wired backbone interface to femto base stations sharing a same paging group identification (PGID).

7. A method comprising:

receiving an indication to page a broadband wireless mobile station;

generating a page for the mobile station;

selecting a subset of all base stations within a service area, wherein the select subset of base stations is based on the base stations that the mobile station is authorized to access; and

transmitting the page over a wired backbone to the select subset of base stations,

wherein selecting a subset of all base stations within a service area comprises accessing a database listing base stations that the mobile station is authorized to access, and

wherein the method further comprises;

communicating with the base stations to maintain the database; and

periodically querying the femto base stations about subscriber group changes.

8. The method of claim 7, further comprising receiving updates from the femto base stations about subscriber group changes and to update the database.

9. A broadband wireless network paging controller comprising:

an interface to communicate with a plurality of macro base stations and a plurality of femto base stations; and

a processor to generate a page for a mobile station and transmit the page over the interface to a select subset of all base stations, the select subset of all base stations including base stations that the mobile station is authorized to access, the processor to select the select subset by accessing a database listing base stations that the mobile station is authorized to access, the processor to communicate with base stations to maintain the database, the processor to periodically query the femto base stations about subscriber group changes.
