Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to offline computing for mobile devices and more particularly to notification delivery to periodically disconnected mobile devices. 
         [0003]    2. Description of the Related Art 
         [0004]    Mobile devices have emerged from mere telephonic communicators to full-fledged portable computing platforms. Originally, designed as a mere merger of a personal digital assistant and a cellular telephone, the modern mobile device integrates the functionality of cellular telephony and data communications so as to provide advanced modes of communication and computing. In particular, the integration of the functionality of cellular telephony and data communications now permits true remote computing utilizing mobile devices as end user clients accessing applications over the Internet. 
         [0005]    Of note, unlike a personal computer fixed in an office environment which enjoys continuous network connectivity, mobile devices frequently lose data connectivity during cellular telephony. Further, mobile devices lose data connectivity when removed from a wireless networking environment, or when the mobile devices travel outside of range of cellular or broadband data connectivity. Yet, some applications utilizing mobile devices as end user clients permit continued computing with changes in application data synchronized once data connectivity becomes re-established. The process of synchronization generally involves a comparison of changed records at a remote server and within the mobile device to identify records to be updated at both ends. 
         [0006]    Further, during periods when a mobile device does not enjoy data connectivity, the remote server queues undelivered notifications intended for delivery to the mobile device in an arrangement commonly referred to as “store and forward”. In store and forward, the remote server periodically re-attempts delivery of the notifications to the mobile device until the mobile device regains connectivity in order to receive the queued notifications. Depending upon the length of time of during which the mobile device remains disconnected, a substantial number of events may have occurred resulting in the undesirable clogging both of the queue in the remote server, as well as network bandwidth resulting from multiple delivery attempts of the notifications by the remote server. 
       BRIEF SUMMARY OF THE INVENTION 
       [0007]    Embodiments of the present invention address deficiencies of the art in respect to notification delivery to mobile devices and provide a novel and non-obvious method, system and computer program product for mobile wireless access point notification delivery for periodically disconnected mobile devices. In an embodiment of the invention, a method for mobile wireless access point notification delivery for periodically disconnected mobile devices is provided. The method includes providing in a wireless access point, a wireless hotspot for different mobile devices and establishing a cellular communications link between the wireless access point and the Internet. The method also includes routing messages between the mobile devices and the cellular communications link through the wireless hotspot. Finally, the method includes identifying a mobile device no longer connected to the wireless hotspot and in response, queuing messages in the wireless access point received from the Internet and directed to the identified mobile device. Subsequently, responsive to a determination that the identified mobile device has reconnected to the wireless hotspot, the method includes delivering the queued messages to the identified mobile device. 
         [0008]    In another embodiment of the invention, a mobile wireless access point is provided. The mobile wireless access point includes at least one processor, memory and a cellular radio disposed within a housing, the cellular radio providing a broadband data connection to the Internet. The mobile wireless access point also includes a wireless router coupled to the processor, memory and cellular radio within the housing and configured to generate and maintain a wireless hotspot within a geographic distance of the housing and to route data from the wireless hotspot to the Internet over the broadband data connection. Finally, the mobile wireless access point includes a mobile wireless access point notification delivery module executing in the memory of the housing. The module includes program code enabled upon execution by the at least one processor in the housing to respond to a determination that a mobile device formerly connected to the wireless hotspot no longer is connected to the wireless hotspot by queuing in the memory messages received from the Internet over the broadband connection that are directed to the mobile device, and by subsequently delivering the queued messages to the mobile device in response to a determination that the mobile device has reconnected to the wireless hotspot. 
         [0009]    In one aspect of the embodiment, the program code of the module is further enabled to respond to a determination that a remote server endpoint receiving messages from the mobile device no longer is accessible over the cellular communications network by queuing messages in the memory that are received from the mobile device and that are directed to the remote server endpoint, and by subsequently delivering the queued messages to the previously inaccessible remote server in response to a determination that the remote server endpoint has become accessible. Finally, in another aspect of the embodiment, the program code of the module is further enabled to optimize the queued messages for the remote server endpoint before delivering the queued messages to the remote server endpoint. 
         [0010]    Additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The aspects of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0014]    Embodiments of the invention provide for mobile wireless access point notification delivery for periodically disconnected mobile devices. In accordance with an embodiment of the invention, a mobile wireless access point can establish a cellular data connection with a remote server over both a cellular communications network and the Internet. Also, the mobile wireless access point can establish a wireless data communications link with one or more mobile devices. Thereafter, the mobile wireless access point can act as a proxy to either or both of the cellular communications network and the mobile devices. Specifically, when a mobile device becomes disconnected from the access point, messages directed to the mobile device can be received in the access point and queued for delivery to the mobile device once the mobile device reconnects to the access point. 
         [0015]    Conversely, messages can be received in the access point from the mobile device and routed as directed to a remote server endpoint through the cellular data connection. However, when data connectivity is lost as between the remote server endpoint and the wireless access point the wireless access point can continue to receive and subsequently queue the received messages from the mobile device. Once data connectivity resumes as between the wireless access point and the remote server endpoint, the wireless access point can deliver the queued messages to the remote server endpoint. In this way the loss of connectivity with the server endpoint need not inhibit the mobile devices from sending messages, and the loss of connectivity with the mobile devices need not inhibit the receipt of messages for the mobile devices so as to overburden the cellular communications network. 
         [0016]    In further illustration,  FIG. 1  pictorially shows a computing architecture configured for mobile wireless access point notification delivery for periodically disconnected mobile devices. As shown in  FIG. 1 , a mobile wireless access point  100  can include a housing enclosing at least one processor  110 , memory  120 , a cellular radio  130 A and a wireless networking radio  130 B. The cellular radio  130 A can be configured to establish and maintain a cellular telephonic connection to a cellular network  190 A and to process data communications therethrough from the mobile wireless access point  100  to one or more remote endpoint servers  160  disposed about the Internet  190 B, by way of a network gateway  140 . 
         [0017]    The wireless networking radio  130 B in turn can be configured to establish and maintain a wireless hotspot  170  within a limited geographic distance of the mobile wireless access point  100 . Within the hotspot  170 , short range wireless data communications can be managed between coupled computing devices  180 , for example laptop computers, personal computers, personal digital assistants, tablet computers, smartphones and the like. Further, within the hotspot  170 , data communications can be managed between individual ones of the computing devices  180  and the remote endpoint servers  160  through the cellular network  190 A and the Internet  190 B. 
         [0018]    Of note, a notification delivery module  200  can be disposed within the mobile wireless access point  100 , for example within firmware or other persistent memory of the mobile wireless access point  100 . The module  200  can include program code that when loaded into memory  120  and executed by the processor(s)  110  is enabled to act as a proxy to either or both of the cellular communications network  190 A and the computing devices  180 . Specifically, when the program code determines that one of the computing devices  180  has become disconnected from the mobile wireless access point  100  by way of the hotspot  170  provided thereby, messages directed to the one of the computing devices  180  received in the mobile wireless access point  100  can be queued in notification queue  150  for delivery to the one of the computing devices  180  once the program code detects the reconnection of the one of the computing devices  180  to the mobile wireless access point  100  by way of the hotspot  170 . 
         [0019]    Conversely, the program code of the notification delivery module  200  can be enabled to detect when data connectivity is lost as between one of the remote server endpoints  160  communicating with one of the computing devices  180 . In response, the program code can be enabled to queue messages in the notification queue  150  received from the one of the computing devices  180 . Thereafter, upon the program code detecting that data connectivity has resumed as between the wireless access point  100  and the one of the remote server endpoints  160 , the program code can be enabled to deliver the queued messages to the one of the remote server endpoints  160 . 
         [0020]    Optionally, prior to delivering the queued messages to the one of the remote server endpoints  160 , the queued messages can be optimized, for example consolidated to reduce redundancies in messages. For instance, the queued messages can be organized based upon characteristics of the queued messages including destination target for the messages, e.g. whether or not the target is for a single end user or a group of end users, the identify of a push notification provider of the messages or the type of the sending or target device. In addition, in the instance where the recipient device or recipient provider of the message can receive customized payloads, the messages can be further optimized by performing data compression upon the messages intended for devices or providers able to handle the customized payloads. 
         [0021]    In yet further illustration,  FIG. 2  is a flow chart depicting a process for mobile wireless access point notification delivery for periodically disconnected mobile devices. The process can begin in block  210  with the receipt of a message from over the Internet directed to a mobile device coupled to the mobile wireless access point by way of a hotspot provided and maintained by the mobile wireless access point. In decision block  220 , it can be determined whether or not the mobile device remains connected to the mobile wireless access point by way of the hotspot. If so, the message can be delivered to the mobile device in block  230 . 
         [0022]    In decision block  220 , if it is determined that the mobile device is not connected to the mobile wireless access point by way of the hotspot, in block  240  the message can be placed in a notification queue instead of routing the message to the mobile device. Thereafter, in decision block  250  it can be determined whether or not the mobile device has reconnected to the mobile wireless access point by way of the hotspot. If in decision block  250  it is determined that the mobile device has reconnected to the mobile wireless access point by way of the hotspot, in block  260  all messages queued for the mobile device can be delivered to the mobile device.
