Apparatus, method and system for providing conditional answering in multiple leg telecommunication sessions

A system for providing conditional answering in a multiple leg telecommunication session, the system comprising:

• a database, the database having stored in a memory a plurality of secondary directory numbers associated with a primary directory number;
• and
• a switching center coupled to the database, the switching center having an interface for receiving an incoming call leg designating the primary directory number and for processing and routing each outgoing call leg associated with each secondary directory number, of the plurality of secondary directory numbers;
• the switching center further providing, when an outgoing call leg of the plurality of outgoing call legs has been conditionally answered, called party information on the conditionally answered outgoing call leg;
• and the switching center further providing, when an outgoing call leg of the plurality of outgoing call legs has been unconditionally answered, a connection between the unconditionally answered outgoing call leg and the incoming call leg to form a communication session.

An apparatus for providing conditional answering in a multiple leg telecommunication session, the apparatus comprising:

• a network interface for reception of an incoming call leg designating a primary directory number and for transmission of a plurality of outgoing call legs;
• a memory having a plurality of secondary directory numbers associated with the primary directory number;
• and
• a processor coupled to the memory and the network interface, wherein the processor, when operative, includes instructions to process and route each outgoing call leg associated with each secondary directory number, of the plurality of secondary directory numbers;
• the processor including further instructions, when an outgoing call leg of the plurality of outgoing call legs has been conditionally answered, to provide called party information on the conditionally answered outgoing call leg;
• and the processor including further instructions, when an outgoing call leg of the plurality of outgoing call legs has been unconditionally answered, to provide a connection between the unconditionally answered outgoing call leg and the incoming call leg to form a communication session.

A system for providing conditional answering in a multiple leg telecommunication session, the system comprising:

• a home location register, the home location register having stored in a memory, in association with a pilot directory number, a plurality of secondary directory numbers and instructions for determining called party information;
• and
• a mobile switching center coupled to the home location register, the mobile switching center having an interface for receiving an incoming call leg designating the pilot directory number and for processing and routing each outgoing call leg associated with each secondary directory number, of the plurality of secondary directory numbers;
• the mobile switching center, following reception of a directive from the home location register, obtaining information from a calling party for a determination of called party information;
• the mobile switching center further providing, when an outgoing call leg of the plurality of outgoing call legs has been conditionally answered, called party information on the conditionally answered outgoing call leg;
• and the mobile switching center further providing, when an outgoing call leg of the plurality of outgoing call legs has been unconditionally answered, a connection between the unconditionally answered outgoing call leg and the incoming call leg to form a communication session.
