System and method for monitoring user interface connectivity state

A server for use in a client-server configuration to provide a user interface synchronization between the server and the client, the server comprising:

• a memory for storing programmed instructions;
• a processor that is communicatively coupled to the memory, the processor executing the programmed instructions to:
• provide a synchronization indicator on the server to maintain a synchronization value, the synchronization indicator being resettable to an initial value, the synchronization indicator being indicative of an operational status of the server;
• reset the synchronization indicator to the initial value in response to a specified operational status of the server;
• receive, at the server, a first request from the client;
• update the synchronization indicator value on the server from the initial value to progress in value in a trend in response to the first request received from the client;
• provide the updated synchronization indicator value to the client in response to the first request received from the client;
• receive a second request from the client in response to providing the updated synchronization indicator value to the client, the second request comprising a reload request;
• and
• provide a reload response to the client in response to the reload request, the reload response being greater in size than a non-reload request.

A client for use in a client-server configuration to provide a user interface synchronization between the server and the client, the client comprising:

• a memory for storing programmed instructions;
• a processor that is communicatively coupled to the memory, the processor executing the programmed instructions to:
• send a first request from the client to the server to (i) prompt a synchronization indicator maintained by the server to be updated in a trend in response to receiving the first request to provide a first synchronization value that represents a server operational status and (ii) prompt a response from the server to provide the first synchronization value from the server to the client;
• receive and store the first synchronization value at the client;
• send a second request from the client to the server to (i) prompt the synchronization indicator to be updated in the trend to provide a second synchronization value and (ii) prompt a response from the server to provide the second synchronization value from the server to the client;
• compare the first synchronization value with the second synchronization value at the client to determine a relationship between the first and second synchronization values;
• and
• perform a user interface recovery action when the relationship between the first and second synchronization values is other than a predetermined relationship.

A method for synchronizing a user interface with a server in a packet switched network, the server being configured for unidirectionally triggered communication with the user interface, the method comprising:

• maintaining a first synchronization value in the user interface;
• sending a request from the user interface to the server to cause (i) a synchronization indicator maintained by the server to be updated in a trend to provide a second synchronization value in response to receiving the request, wherein the synchronization indicator is uniquely associated with the user interface, and (ii) the second synchronization value to be sent to the user interface in response to receiving the request;
• receiving at the user interface the second synchronization value from the server in response to the request;
• comparing the first synchronization value with the second synchronization value received from the server;
• and
• performing a recovery action for the user interface when the comparison results in a determination of a relationship between the first and second synchronization values that is other than a predetermined relationship.

• resetting the synchronization value to the initial value in response to a specified operational status of the server;
• receiving a first request from the user interface;
• updating the synchronization value on the server from the initial value to progress in value in a trend in response to the first request received from the user interface;
• providing the updated synchronization value to the user interface in response to the first request received from the user interface;
• receiving a second request from the user interface in response to providing the updated synchronization value to the user interface, the second request comprising a reload request;
• and
• providing a reload response to the user interface in response to the reload request, the reload response being greater in size than a non-reload request.
