Abstract

Disclosed are a wireless communication system, method, and information processing system for optimizing paging channel utilization. The method includes determining a mobility state of the wireless device (104). If the mobility state of the wireless device (104) is a mobile state, a signal is generated for a page to be transmitted to a set of base stations (110) in a paging area (402) that the wireless device (104) is currently located in. If the mobility state of the wireless device (104) is a stationary state, a subset of base stations from the set of base stations (110) within the paging area (402) is selected. A signal is then generated for a page to be transmitted to the subset of base stations.

Claims

determining a mobility state of a wireless device;

if the mobility state of the wireless device is a mobile state,

generating a signal for a page to be transmitted to a set of base stations in a paging area that the wireless device is currently located in; and

if the mobility state of the wireless device is a stationary state,

selecting a subset of base stations from the set of base stations within the paging area, and

generating a signal for a page to be transmitted to the subset of base stations.

2. The method of claim 1, wherein the subset of base stations includes a base station for a home wireless communication cell and at least one base station for a wireless communication cell neighboring the home wireless communication cell.

3. The method of claim 1, wherein the determining the mobility state further comprises at least one of:

receiving an authentication, authorization, and accounting profile associated with the wireless device including provisioning data; and

receiving an idle state request from the wireless device including the mobility state of the wireless device.

4. The method of claim 3, wherein the determining the mobility state further includes receiving an identification of at least one base station that the wireless device is currently communicating with.

5. The method of claim 1, wherein the generating a signal for a page to be transmitted to the subset of base stations further comprises:

transmitting the page to the subset of base stations;

determining if a paging response has been received from the wireless device; and
