  • Method and arrangement for upstream timeslot assignment, and communication system wherein the method is used
    Patent number: 6298049
    Abstract: To assign upstream timeslots to network terminals (ANT1, ANT2, ANT3, ANT4) in a communication network wherein a common link (L) is shared in a time multiplexed way in the upstream direction from the network terminals (ANT1, ANT2, ANT3, ANT4) towards the main station (LIM), the main station (LIM) keeps track of at least one grant table (T1, T2) and at least one exceptional grant queue (Q1, Q2). The grant table (T1, T2) is scanned cyclically and the main station (LIM) downstream broadcasts a grant message for each entry of this grant table (T1, T2). This grant message assigns an upstream timeslot to the network terminal (ANT1) whose identifier (ID1) is memorized in the scanned table entry. If the scanned entry is empty, the main station (LIM) assigns an upstream timeslot to the network terminal (ANT2) whose identifier (ID2) is read from a non-empty exceptional grant queue (Q1, Q2).
