A system and method are provided for enabling access to presence status for mobile devices. The method comprises receiving, via an application programming interface, an application inquiry, the application inquiry requesting a presence data for at least one mobile device; responsive to receiving said inquiry, obtaining network data from one or more network infrastructure nodes associated with providing service to the at least one mobile device; determining a response to the application inquiry based upon the network data; and providing the response via the application programming interface.

System and method for providing access to presence status for mobile devices

A system and method are provided for enabling access to presence status for mobile devices. The method comprises receiving, via an application programming interface, a subscription request, the subscription request requesting a presence data for at least one mobile device; registering a subscription for a subscriber device according to the subscription request; obtaining network data from one or more network infrastructure nodes associated with providing service to the at least one mobile device; determining that at least a portion of the network data is associated with the subscription; and providing the at least a portion of the network data to the subscriber device via the application programming interface.

A router receives from a host service a message which is intended for delivery to a mobile device via a wireless network. The message includes an indication field which includes a return packet indication on whether to send a return packet to the host, an identifier field which includes an identifier which identifies the device, and a payload field which includes a payload of the message. When the indication is set to a first, setting and the message is not being delivered to the device, the router sends to the host a return packet which indicates that the message is not being delivered to the device. When the indication is set to a second setting and the message is not being delivered to the device, the router does not send to the host the return packet which indicates that the message is not being delivered to the device.

System and method of message delivery in a wireless communication network

A router system receives from a host service a message which is intended for delivery to a mobile device via a wireless network. The message includes at least a first field having an identifier which identifies the mobile device, a second field having a payload of the message, and a third field having a return packet indication on whether to return a return packet to the host service. The router system examines the indication in the message and, if the indication is set to a first setting, the router system returns to the host service a return packet which indicates a status associated with the message for delivery to the mobile device. If the indication is set to a second setting, then the router system does not return to the host service the return packet which indicates the status associated with the message for delivery to the mobile device.

A router system maintains a status of a wireless device of either available or unavailable. The status of available may be indicative of the wireless device being in-coverage with a wireless network, whereas the status of unavailable may be indicative of the wireless device being out-of-coverage with the wireless network. The router system is adapted to receive, from a host service, a user data message that is addressed to an address of the wireless device. The user data message has a user data payload and one or more request parameters, where the one or more request parameters instruct the router system on whether to return at least a portion of the user data message to the host service when the device status is unavailable. In response to the user data message being received at the router system when the device status is available, the router system delivers the user data message to the wireless device via the wireless network. In response to the user data message being received at the router system when the device status is unavailable, the router system fails to delivery the user data message to the wireless device but sends the at least user data message portion to the host service.

A wireless communication system, comprising a host service, a wireless router system coupled to the host service, a wireless network coupling the wireless router system and a wireless mobile communication device ('mobile device'), adaptively delivers data to the mobile device in the wireless communication system using a notification message delivery mechanism. Mobile device reports its session state to the wireless router at a regular interval or if there is a change in state. The host service sends out a message to the wireless router to query the state of the mobile device. If the state of the mobile device is determined to be in coverage (or logged on), the host service sends down the data message to the mobile device using a payload message (MTH) with certain parameters configured. The data is temporarily stored at the wireless router. If the device is available, the message is sent to the device over the wireless network. If the device is not available, the wireless router returns the payload message back to the host service, updating the status of the device. The wireless router also reports to the host service any change in device state. If the device is back in coverage, the payload message is then resent from the host service to the device.
