Abstract

The invention includes a method and apparatus for notification and delivery of messages to mobile users using a secure client associated with a user device. The secure client includes a power module, a communication module, a storage module, and an alert module. The power module powers the client device independent of a power state of the user device. The communication module receives a wake-up message and responsively triggers the secure client to switch from an inactive state to an active state without changing the power state of the user device, initiates a secure connection with a secure gateway in response to the wake-up message, and requests and receives a user message from a messaging application using the secure connection. The storage module stores the received message independent of the power state of the user device. The alert module activates an alert to indicate that the message is available.

Claims

1. A secure client for use with a user device, comprising:

a power module for powering the secure client independent of a power state of the user device;

a communication module for receiving a wake-up message adapted for triggering the secure client to switch from an inactive state to an active state without changing the power state of the user device, the communication module adapted for initiating a secure connection with a secure gateway in response to receiving the wake-up message, the communication module adapted for requesting and receiving a message from a messaging application using the secure connection;

a storage module for storing the received message; and

an alert module for activating an alert to indicate that the message is available.

2. The secure client of claim 1, wherein the alert module activates the alert in response to a determination that the user device is in an inactive power state.

3. The secure client of claim 1, further comprising:

an alert device for presenting the activated alert.

4. The secure client of claim 3, wherein the alert device comprises at least one of a visual alert device and an audible alert device.

5. The secure client of claim 1, further comprising:

an interface module for interfacing the secure client with the user device and providing the stored message toward the user device.

6. The secure client of claim 1, further comprising:

a processor for providing a state change message toward the user device, wherein the state change message is adapted for switching the power state of the user device from an inactive state to an active state.

7. The secure client of claim 1, wherein the alert module deactivates the alert in response to the message being provided toward the user device.

8. The secure client of claim 1, wherein the storage module is configured to store the received message until the received message is provided toward the user device.

9. The secure client of claim 1, wherein the secure client is configured to provide the stored message toward the user device in response to detecting that the user device is in an active state.

10. The secure client of claim 1, wherein the secure client is configured to provide the stored message toward the user device in response to detecting the user device switching from an inactive state to an active state.

11. The secure client of claim 1, further comprising:

a processor for controlling providing of the message from the storage module of the secure client toward the user device.

12. A method, comprising:

receiving, from a messaging application, a request for user reachability information in response to a user message becoming available;

determining whether a secure connection exists between a secure gateway of a private network and a secure client; and

if the secure connection does not exist, providing toward the secure client a message adapted to trigger the secure client to switch from an inactive state to an active state, to request the secure connection to the secure gateway and, upon establishment of the secure connection, to request the available message from the messaging application of the private network;

wherein the secure client operates independent of a power state of a user device associated with the secure client.

13. The method of claim 12, further comprising:

obtaining an address of the secure client; and

providing to the secure client, using the obtained address, the message adapted to trigger the secure client to switch from an inactive state to an active state.

14. The method of claim 12, further comprising:

if the secure connection does exist, providing an address of the secure client to the messaging application of the private network, wherein the address of the secure client is adapted for use by the messaging application to provide the available message to the secure client over the secure connection.

15. A secure client for use with a user device, comprising:

a power module for powering the secure client independent of a power state of the user device;

a communication module for receiving a wake-up message adapted for triggering the secure client to switch from an inactive state to an active state without changing the power state of the user device, and for receiving a message available from a messaging application;

a storage module for storing the message; and

a processor for controlling providing of the message from the storage module toward the user device in response to a determination that the user device is in an active state.
