Method and system for selective application of cellular-PBX integration service
First Claim
1. A method comprising:
- receiving into a cellular radio access network (RAN) a call request seeking to set up a call for a cellular wireless communication device (WCD) that is operating in a wireless coverage area of the RAN, wherein the call is a call to a called party;
responsively making a determination of whether the WCD is currently checked-into a cellular-PBX integration service to which the WCD subscribes;
if the determination is that the WCD is currently checked-into the cellular-PBX integration service, then setting up the call to an IP PBX server that serves the WCD; and
if the determination is that the WCD is not currently checked-into the cellular-PBX integration service, then setting up the call to the called party without setting up the call to the IP PBX server,wherein the cellular RAN includes a mobile switching center (MSC) that is communicatively linked with a service control point (SCP) to which the MSC signals for call processing guidance in response to the call request, the SCP maintaining a subscriber profile record for the WCD, wherein the subscriber profile record includes an indication of whether the WCD is currently checked-into or checked-out of the cellular-PBX integration service, andwherein making the determination of whether the WCD is currently checked-into the cellular-PBX integration service comprises the SCP referring to the subscriber profile record to determine whether the WCD is currently checked-into or checked-out of the cellular PBX integration service.

Abstract
A method and system for selectively applying a cellular-PBX integration service. When a radio access network (RAN) receives a call request seeking to set up a call for a cellular wireless communication device (WCD) that is operating in the coverage area of the RAN, a determination is made as to whether the WCD is currently checked-into a cellular-PBX integration service. A service control point (SCP), for instance, may make the determination. If the determination is that the WCD is currently checked-in, then the call is set up to an IP PBX server that services the WCD, and the IP PBX server may then handle the call as it would handle a call placed to any IP PBX extension. Further, differential billing can be applied, charging an enterprise billing-account for the call if the WCD is checked-in, and charging a WCD billing-account for the call if the WCD is not checked-in.

16. A system comprising:
-
a cellular radio access network (RAN) comprising (i) a base station that radiates to produce a wireless coverage area and (ii) a mobile switching center (MSC) that provides connectivity between the base station and the public switched telephone network; a service control point (SCP) communicatively linked with the MSC; subscriber profile data stored at the SCP, indicating whether a cellular wireless communication device (WCD) is currently checked-into or checked-out of a cellular-PBX integration service to which the WCD subscribes; a media gateway system comprising (i) a media gateway arranged to engage in bearer communication with the mobile switching and (ii) a media gateway controller arranged to engage in signaling communication with the mobile switching center and with the media gateway; a call session control function (CSCF) arranged to engage in signaling communication with the media gateway controller; and an IP PBX server arranged to serve a plurality of enterprise telephone stations that are situated on an enterprise packet-switched network, the IP PBX server being further arranged to engage in signaling communication with the CSCF and bearer communication with the media gateway, wherein the MSC receives a request to set up a call for the WCD when the WCD is operating in the wireless coverage area, the MSC responsively signals to the SCP, the SCP determines based on the subscriber profile data the WCD is currently checked-into the cellular-PBX integration service, and the SCP responsively instructs the MSC to set up the call to the media gateway system for connection of the call in turn to the IP PBX server. - View Dependent Claims (17, 18)
