Abstract

The paper discusses congestion relief using immediate assignment on the TCH (traffic channel). The impact of various immediate assignment strategies and their implementation in a live network are discussed. The impact of CBCH and alleviation of the resulting congestion by immediate assignment have been computed. The effect of paging load is discussed. The impact of immediate assignment on SMS (short message service), location updates, IMSI (international mobile subscriber identity) attach/detach, directed retry and LAPD concentration is analyzed. The impact of immediate assignment on the TCH strategy in Phase 1 and Phase 2 mobile stations and statistical counters is discussed. Detailed analytical results for each channel allocation profile are presented.
