A first group of spring members are mechanically coupled to the top portion of the frame structure and a second group of spring members are mechanically coupled to the bottom portion of the frame structure. In one illustrative embodiment, each spring member of the second group of spring members has a frame hook member that is mechanically coupled to the bottom portion of the frame structure and a bed hook member that includes an end portion that is configured to be within a projection of a body of the spring member and is coupled to the rebounding surface.

Abstract: A three-way communication session is established between a first and a second party, wherein the first party is additionally connected to a third party via a previously established communication. An indication (such as the telephone number associated with the third party, an alphanumeric character, or an icon) is then transmitted to the second party to notify him/her of the presence of the third party in the three-way communication session.
