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 client device independent of a power state of the user device;

a communication module for receiving a wake-up message and responsively 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 received message to the user device in response to the power state of the user device switching from an inactive power state to an active power state.

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. A method for use by a secure client of a user device, comprising:

in response to receiving a wake-up message associated with a user message, initiating a request to establish a secure connection between the secure client and a secure gateway;

initiating a request to retrieve the user message;

receiving the user message over the secure connection;

storing the received user message; and

activating an alert indicating that the user message is available, wherein the alert is presented by the secure client;

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

9. The method of claim 8, further comprising:

providing a state change message to 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.

10. The method of claim 9, further comprising:

in response to the power state of the user device switching to the active state, retrieving the stored user message, decrypting the stored user message, and providing the decrypted user message to the user device.

11. The method of claim 10, further comprising:

deactivating the alert in response to the decrypted user message being provided toward the user device.

12. The method claim 10, further comprising:

presenting the user message using at least one user interface of the user device.

13. The method of claim 8, wherein the user message comprises one of a text message, a voicemail message, and a multimedia message.

14. The method of claim 8, wherein the wake-up message comprises a Short Messaging Service (SMS) message.

15. 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.

16. The method of claim 15, 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.

17. The method of claim 15, 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.

18. The method of claim 15, further comprising:

receiving the available message at the secure client over the secure connection;

storing the received message; and

activating an alert indicating that the user message is available, wherein the alert is presented by the secure client.

19. The method of claim 15, wherein the user message comprises one of a text message, a voicemail message, and a multimedia message.

20. The method of claim 15, wherein the message adapted to trigger the secure client to switch from an inactive state to an active state comprises a Short Messaging Service (SMS) message.
