摘要:
An aircraft based communication system (10) defining a wireless service area (20) is disclosed. The communication system (10) includes a communication gateway (30) connected to a terrestrial based communication network. A first aircraft (12) is located in proximity to the wireless service area (20). The first aircraft (12) communicates with the gateway (30) and communicates with at least one subscriber (24) located within the wireless service area (20). The first aircraft (12) transmits a first control signal (16) within the wireless service area (20). A second aircraft (14) is located in proximity to the wireless service area (20). The second aircraft (14) being operable for communicating with the gateway (30) and being operable for communicating with the subscriber (24) located within the wireless service area (20). The second aircraft (14) flies in proximity to the first aircraft (12) for transferring communication sessions (56, 58) from the first aircraft (12) to the second aircraft (14) and maintaining a constant communication link between the subscriber (24) and the terrestrial based communication network.
摘要:
A network (30) of a telecommunication system (100) receives requests (31) for feature transfers from one user (10) to another user (20). In addition, network initiated feature transfer marks a call agent (61) for feature transfer. Subsequent call attempts from a call agent (51) are redirected (63) by the network.
摘要:
The voice signaling gateway (10) provides group call and call back services among iDEN network (20) users (21) and a number of other various networks (30-60) users (31-62). The voice signaling gateway has packet data interface (17) and web interface (16) In an alternate embodiment of the invention, an integrated applications server (70) is added to the voice signaling gateway (100) to provide group call services. The integrated applications server has the functions for supporting group calls which were within the voice signaling gateway (10) and forms a stand-alone special feature system.
摘要:
A method for providing dynamic group call among a group of users both wireless (10-30) and wireline (40) places the selectability of the call in the hands of an originating user (10). An originating user (10) may make a fixed number of entries (80). The originating user (10) can create a dynamic group call, add a group call list for later execution, add a member to the group call list, or create a dynamic group call list and immediately execute a group call (92). The method for dynamic group call also provides for selecting a time to live for each group call entry (81) in database (60). This parameter time to live is directly selectable by the originating user (167) or the server. In addition, any member to a previous or existing group call may rejoin or reestablish the dynamic group call (220).
摘要:
For a network server (35) communicating with a wireless unit (10) via a Session Initiation Protocol, a retransmission method (50) first sets a timer based upon a time likely for a mobile unit to respond (54). Then the network server waits for a response (56). When the timer set for the kind of mobile unit being used expires (64), a retransmit of the original SIP request takes place (68). Optionally, modes for waiting may include a linear mode (72) and an exponential mode (74).
