Title: Packet communication system, identifier allocation method, and net-side apparatus
Inventor: UMAYABASHI MASAKI
IPC: H04Q7/00
Filed: 2001-03-13
Abstract: PROBLEM TO BE SOLVED: To solve the problem that the number of pieces of terminal-side apparatus that can send data cells to a net-side apparatus is limited by the total number of identifiers in a medium-sharing one-to-many communication system. SOLUTION: The packet communication system comprises pluralities of pieces of terminal-side apparatus, and a net-side apparatus having a dynamic identifier allocation function 141 and a time slot allocation function 1242. The dynamic identifier allocation function 141 sends identifier information that is allocated to each terminal-side apparatus in an initial setting state to each terminal-side apparatus by a control signal. Also, when an identifier release request is received from an identifier control function 100 of the terminal-side apparatus in a normal state, the state of the identifier that is allocated to the terminal-side apparatus is changed to a non-allocation state.  Also, when the identifier release request is received, the identifier in the non-allocation state is retrieved, the identifier is changed to the allocation one when the identifier in the non-allocation state exists, and the identifier that is allocated to the terminal-side apparatus of the request transmission source is notified.
