Abstract
An Integrated Digital Enhanced Network system (1) includes a base radio (104) interconnected to a plurality of transcoders (4) located at central offices (2). The base radio (104) time division multiplexes voice packets from the plurality of transcoders (4) into a time division multiplexed signal frame (20). Each signal frame (20) includes a plurality of sequential frames (204). Each sequential frame (204) includes a predetermined number of slots (202) based upon a channel interleave. Each of the slots (202) includes a slot descriptor block (2024), and a plurality of subslots (e.g., 2026, 2028). The slot descriptor block (2024) alternatively contains overhead information for the plurality of subslots (e.g., 2026, 2028). The subscriber device (30) demultiplexes each sequential frame (204) and receives a specific slot (202) and a specific subslot of the specific slot based upon an assigned slot offset. The subscriber device (30) executes a handover process (600) for determining a timing for jumping to a time division signal frame (21) generated by a new base radio.
