Title: Method using request assignment multiple access protocol
Inventor: JAME L PURIETO JR
IPC: H04B7/15
Filed: 2000-03-15
Abstract: PROBLEM TO BE SOLVED: To efficiently use an up-link channel. SOLUTION: A user of a common facility transmits a reservation request to reserve a time slot of a major flow resource to a satellite (14), and when no reply message is returned (18), it transmits the request again (20) assuming a collision has occurred. When a DAMA processor receives the reservation request, the processor discriminates whether the request is to be permitted, to be rejected or to be delayed on the basis of whether reservation by the user is already in existence, the length of a reservation request and the congestion state of a destination down-link port.  When the processor permits the request, the processor issues to the user a reservation permission message including time, frequency and length to send data onto the major flow channel, and the user awaits the arrival of a reserved time (22) on the basis of this message and transmits the data to the major flow resource.
