Method and system for providing wireless-specific services for a wireless access network

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.
