Systems, methods, and apparatus for communicating the state of a wireless user device in a wireless domain to an application server in an internet protocol (IP) domain

A method for communicating the state of a wireless user device in a wireless domain to an application server in an Internet protocol domain, the method comprising:

• at a wireless user device configured to operate in a wireless domain, detecting a change of state of the wireless user device and sending, via an Internet protocol multimedia subsystem (IMS) gateway node, a messaging service message that includes status information indicating a state of the wireless user device from the wireless user device to an application server configured to operate in an Internet protocol (IP) domain, wherein the messaging service message is one of a short message service (SMS) message or a multimedia messaging service (MMS) message, wherein the gateway node receives the message from the wireless domain in a first format and converts the message from the first format into a second format, wherein the first format is one of a signaling system 7 (SS7) format, a short message peer-to-peer (SMPP) format, a computer interface to message distribution (CIMD) format, a hypertext transport protocol (HTTP) format, a hyper text transport protocol secure (HTTPS) format, and a short message service center (SMSC) format and wherein the second format is one of a session initiation protocol (SIP) format, a session description protocol (SDP) format, and an Internet protocol (IP) format;
• and
• at the application server, receiving, from the IMS gateway node, the status information indicating a state of the wireless user device and providing at least one service to the wireless user device based on the state of the wireless user device.

An apparatus for communicating the state of a wireless user device in a wireless domain to an application server in an Internet protocol domain, the apparatus comprising:

• a wireless user device configured to operate in a wireless domain and configured to send a messaging service message containing information indicating a current state of the device to an Internet protocol multimedia subsystem (IMS) gateway node, wherein the messaging service message is one of a short message service (SMS) message or a multimedia messaging service (MMS) message, wherein the gateway node receives the message from the wireless domain in a first format and converts the message from the first format into a second format, wherein the first format is one of a signaling system 7 (SS7) format, a short message peer-to-peer (SMPP) format, a computer interface to message distribution (CIMD) format, a hypertext transport protocol (HTTP) format, a hyper text transport protocol secure (HTTPS) format, and a short message service center (SMSC) format and wherein the second format is one of a session initiation protocol (SIP) format, a session description protocol (SDP) format, and an Internet protocol (IP) format;
• and
• a client application, on the wireless user device, for detecting a change of state of the device, and, in response to detecting the change of state, instructing the device to send the messaging service message containing information indicating the current state of the device to the IMS gateway node.
