Abstract

A push proxy server for pushing data to a wireless device having a coverage state of online or offline. The push proxy server comprises a coverage state detector, memory, a data store, and a transceiver. The coverage state detector determines the coverage state of the wireless device. The memory stores a coverage state indicator for indicating the coverage state of the wireless device. The data store stores the data to be pushed to the wireless device when the coverage state indicator indicates the wireless device is offline. The transceiver transmits the data to the wireless device when the coverage state indicator indicates the wireless device is online. A method for implementing the push proxy server is also described.

Claims (25)

1. A push proxy server for pushing data to a wireless device having a coverage state of online or offline, the push proxy server comprising:

(a) a coverage state detector for determining the coverage state of the wireless device;

(b) memory for storing a coverage state indicator for indicating the coverage state of the wireless device;

(c) a data store for storing the data to be pushed to the wireless device when the coverage state indicator indicates the wireless device is offline;

(d) a transceiver for transmitting the data to the wireless device when the coverage state indicator indicates the wireless device is online; and

(e) a waste manager configured to delete stale data from the data store in accordance with a predefined expiry term prior to transmitting the data to the wireless device, and wherein the expiry term is defined by an expiry field of a message header in a message containing the data, and wherein the expiry field indicates that the stale data is to be deleted upon receipt of replacement data, the replacement data comprising an updated version of the stale data.

2. A push proxy server for pushing data to a wireless device having a coverage state of online or offline, the push proxy server comprising:

(a) a coverage state detector for determining the coverage state of the wireless device;

(b) memory for storing a coverage state indicator for indicating the coverage state of the wireless device;

(c) a data store for storing the data to be pushed to the wireless device when the coverage state indicator indicates the wireless device is offline;

(d) a transceiver for transmitting the data to the wireless device when the coverage state indicator indicates the wireless device is online; and

(e) a waste manager configured to delete stale data from the data store in accordance with a predefined expiry term prior to transmitting the data to the wireless device, wherein the expiry term is defined by an expiry field of a message header in a message containing the data, and wherein the waste manager sends a notification to a sender of the data when stale data is deleted.

3. A method for pushing data from a push initiator to a wireless device having a coverage state of online or offline, the method comprising the steps of:

(a) determining, at a push proxy server, the coverage state of the wireless device;

(b) storing in memory a coverage state indicator for indicating the coverage state of the wireless device;

(c) storing in a data store the data to be pushed to the wireless device when the coverage state indicator indicates the wireless device is offline;

(d) transmitting the data to the wireless device when the coverage state indicator indicates the wireless device is online; and

(e) deleting stale data from the data store in accordance with a predefined expiry term prior to transmitting the data to the wireless device, wherein the expiry term is defined by an expiry field of a message header in a message containing the data, and wherein the expiry field indicates that the stale data is to be deleted upon receipt of replacement data, the replacement data comprising an updated version of the stale data.

4. A method for pushing data from a push initiator to a wireless device having a coverage state of online or offline, the method comprising the steps of:

(a) determining, at a push proxy server, the coverage state of the wireless device;

(b) storing in memory a coverage state indicator for indicating the coverage state of the wireless device;

(c) storing in a data store the data to be pushed to the wireless device when the coverage state indicator indicates the wireless device is offline;

(d) transmitting the data to the wireless device when the coverage state indicator indicates the wireless device is online; and

(e) deleting stale data from the data store in accordance with a predefined expiry term prior to transmitting the data to the wireless device, wherein the expiry term is defined by an expiry field of a message header in a message containing the data, and

(f) further comprising the step of sending a notification to a sender of the data when stale data is deleted.
