Methods and apparatus for re-establishing communication for a wireless communication device after a communication loss in a wireless communication network

A method for use in re-establishing a data connection between an application server and a wireless communication device operating in a wireless communication network, the method comprising the acts of:

• storing an identifier of the application server in association with an identifier of the wireless device;
• receiving an indication of a communication loss between the wireless device and the wireless network which causes the data connection to be terminated;
• after the communication loss, receiving an indication that communication is re-established between the wireless device and the wireless network;
• and
• providing the stored association of identifiers of the application server and the wireless device to assist in re-establishing the data connection between the wireless device and the application server.

A method for use in re-establishing data communication over a data connection between an application server and a wireless communication device after a communication loss between the wireless device and a wireless communication network which causes the data connection to be terminated, the method comprising the acts of:

• storing identifiers of application servers in association with identifiers of wireless communication devices between which data communications over data connections were established or pending;
• and
• after the wireless device recovers from the communication loss:
• assisting in re-establishing the data connection between the application server and the wireless device with use of a stored association between an identifier of the application server and an identifier of the wireless device.

A server, comprising:

• a data storage medium;
• computer instructions stored on the data storage medium;
• a computer processor which executes the computer instructions for use in re-establishing data communication over a data connection between an application server and a wireless communication device after a communication loss between the wireless device and a wireless communication network which causes the data connection to be terminated, by performing the following acts of:
• storing identifiers of application servers in association with identifiers of wireless communication devices between which data communications over data connections were established or pending;
• and
• after the wireless device recovers from t he communication loss, providing an identifier of the application server to assist in re-establishing the data connection between the application server and the wireless device.

A server for facilitating a re-establishment of data communications over a data connection between an application server and a wireless communication device, the server comprising:

• a data storage medium;
• computer instructions stored on the data storage medium;
• a computer processor of the server which executes the computer instructions for:
• after communication loss between the wireless device and a wireless communication network which causes the data connection to be terminated, receiving a plurality of connection requests from the application server intended for receipt by the wireless device for re-establishing the data connection;
• and
• limiting a number or a rate of the connection requests from the application server received by the wireless device during the communication loss between the wireless device and the wireless network.
