Patent ID: 8775617

Claim:
A method for reestablishing a communication session connection comprising: a first communication terminal device establishing a communication session via communications with a switch device; the first communication terminal device experiencing a connection failure that makes the first communication terminal device unavailable for a first period of time during the communication session; the switch device detecting the connection failure of the first communication terminal device; in response to detecting the connection failure of the first communication terminal device, the switch device monitoring communication events involving the first communication terminal device for a second period of time and saving information related to the monitored communication events in a list; and upon a determination that the first communication terminal device reestablished a connection with the switch device for restarting the communication session within the second period of time: the switch device sending a first message to the first communication terminal device, the first message comprising information relating to at least a portion of information saved in the list, and the first communication terminal device evaluating the first message to determine whether to engage in discovery services involving other communication devices for updating a user interface of the first communication terminal device.
