Whether the device is registered on the wireless access network is determined. If the mobile device is not registered, whether the mobile device is active is determined at a mobility control function (MCF). If the mobile device is active, the call is connected to the mobile device with a call agent based on a temporary line directory number (TLDN) assigned by the MCF and passed to the call agent in an extended session initiation protocol (SIP) message. ## Claims ### Claim 1 (canceled) ### Claim 2 (canceled) ### Claim 3 (canceled) ### Claim 4 (canceled) ### Claim 5 (canceled) ### Claim 6 (canceled) ### Claim 7 (canceled) ### Claim 8 (canceled) ### Claim 9 (canceled) ### Claim 10 (canceled) ### Claim 11 (canceled) ### Claim 12 (canceled) ### Claim 13 (canceled) ### Claim 14 (canceled) ### Claim 15 (canceled) ### Claim 16 (canceled) ### Claim 17 (canceled) ### Claim 18 (canceled) ### Claim 19 (canceled) ### Claim 20 (canceled) ### Claim 21 (canceled) ### Claim 22 An apparatus for providing call handling for a wireless access network, comprising: a call agent of the wireless access network operable to receive a call origination for a call associated with a mobile device, wherein the call agent is further operable to determine whether the mobile device is registered on the wireless access network and if the mobile device is not registered, a determination is made as to whether the mobile device is active, if the mobile device is active then the call is connected to the mobile device based on a temporary line directory number (TLDN) that was passed to the call agent in an extended session initiation protocol (SIP) message. ### Claim 23 (depends on 22) The apparatus of claim 22, wherein if the mobile device is not active, the call is connected to a voice mail server identified by profile information for the mobile device. ### Claim 24 (depends on 22) The apparatus of claim 22, wherein if the mobile device is registered, profile information for the mobile device is retrieved, whereby the call is routed to the mobile device in the wireless access network using a SIP message. ### Claim 25 (depends on 22) The apparatus of claim 22, wherein the call agent comprises wireless-specific interfaces. ### Claim 26 (depends on 22) The apparatus of claim 22, wherein the call agent is operable to support wireless-specific location based services. ### Claim 27 (depends on 22) The apparatus of claim 22, wherein a bearer path associated with the call is anchored at a gateway associated with a public switched telephone network (PSTN). ### Claim 28 (depends on 22) The apparatus of claim 22, wherein a bearer path associated with the call is anchored in a wireless-specific access gateway. ### Claim 29 (depends on 22) The apparatus of claim 22, wherein events detected at a mobility control function (MCF), which is operable to communicate with the call agent, serve as a basis for intelligent network (IN) triggers. ### Claim 30 (depends on 22) The apparatus of claim 22, wherein the call supports a selected one or more services that can be enabled by wireless-specific extensions, the services being part of a group of services and the group consisting of: a) feature activation; b) feature deactivation; c) calling number identification; d) call forwarding unconditional; e) call forwarding no answer; f) call forwarding default; g) call forwarding busy; and h) voice mail waiting notification. ### Claim 31 A method for enlisting one or more end users in a network environment in which call handling for a wireless access network occurs, comprising: enlisting one or more end users in a billing plan associated with network communications; generating a bill associated with one or more of the end users, the bill being based on the billing plan; and facilitating network communications for one or more of the end users in response to the end users being enlisted in the billing plan, whereby the network communications includes a protocol that comprises: receiving at a call agent of the wireless access network a call origination for a mobile device; determining whether the mobile device is registered on the wireless access network; if the mobile device is not registered, determining at a mobility control function (MCF) whether the mobile device is active; and if the mobile device is active, connecting the call to the mobile device with a call agent based on a temporary line directory number (TLDN) assigned by the MCF and passed to the call agent in an extended session initiation protocol (SIP) message. ### Claim 32 (depends on 31) The method of claim 31, further comprising: if the mobile device is not active, connecting the call to a voice mail server identified by profile information for the mobile device. ### Claim 33 (depends on 31) The method of claim 31, further comprising: if the mobile device is registered, retrieving profile information for the mobile device at the call agent; and routing the call to the mobile device in the wireless access network through the MCF using a SIP message. ### Claim 34 (depends on 31) The method of claim 31, further comprising: allocating bandwidth to one or more of the end users based on the billing plan. ### Claim 35 (depends on 31) The method of claim 31, further comprising: anchoring a bearer path associated with the call at a gateway associated with a public switched telephone network (PSTN). ### Claim 36 (depends on 31) The method of claim 31, further comprising: anchoring a bearer path associated with the call at a gateway associated with a wireless-specific access gateway. ### Claim 37 (depends on 31) The method of claim 31, further comprising: detecting events at the MCF, which is operable to communicate with the call agent, that serve as a basis for intelligent network (IN) triggers. ### Claim 38 (depends on 37) The method of claim 37, wherein the triggers are associated with voice or wireless Internet communications. ### Claim 39 (depends on 31) The method of claim 31, further comprising: providing location based services to the mobile device via the call agent. ### Claim 40 (depends on 39) The method of claim 39, wherein location specific information is passed in an Invite message. ### Claim 41 (depends on 40) The method of claim 40, wherein the location based services comprise a location identification restriction (LIR) feature and a location identification presentation (LIP) feature.
