Abstract: A system for multi-tasking access to applications by a clientless mobile phone. The system includes at least a clientless mobile interaction (CMI) application server communicatively connected to a network; at least one application server communicatively connected to a network, the at least one application server having at least a first application executable on the clientless mobile phone and a second application executable on the clientless mobile phone; and a presentation layer gateway communicatively connected to the network, wherein the CMI application server enables the clientless mobile phone communicatively connected to the presentation layer gateway by at least a presentation layer protocol to access the first application and the second application executed on the CMI application server while presenting a menu on the clientless mobile phone for seamless switching between the first application and the second application executed on the CMI application server.
Abstract: A method is provided for handling a call communication session via a communication address associated with a private network using Unstructured Supplementary Service Data (USSD) protocol. USSD messages are used between the wireless private network subscriber and a wireless network to provide the subscriber with information about the caller, and routing options of the call. The subscriber can also inform the wireless network using USSD messages how to proceed with the call. USSD messages such as but not limited to, transferring the call to another subscriber with canned messages, transferring the call to a subscriber's voice mail, establishing a conference call, swapping to other call, creating new call, consulting with other person, transferring to specific predefined person, hold, consulting with other person via canned message, etc. Another method is exchanging the device status information using USSD messages.
Abstract: A system and apparatus for call control management using the Unstructured Supplementary Service Data (USSD) protocol. The system and apparatus uses USSD messages between the wireless private network subscriber and a wireless network to provide subscribers with information about callers and routing options of the call. The subscriber can also inform the system using USSD messages how to proceed with the call. The system provides USSD messages such as but not limited to, transferring the call to another subscriber with canned messages, transferring the call to a subscriber's voice mail, establishing a conference call, swapping to other call, creating new call, consulting with other person, transferring to specific predefined person, hold, consulting with other person via canned message, etc. The system and apparatus also exchanges device status information using USSD messages.
