Propomos e analisamos um novo esquema de transferência eficiente denominado esquema de canal de classificação dividida em redes UMTS, e analisamos o desempenho em nível de chamada do esquema de canal de classificação dividida e, em seguida, o desempenho em nível de pacote do tráfego de downlink em redes comutadas por circuito UMTS. Para reduzir a probabilidade de bloqueio de chamadas originadas e a probabilidade de terminação forçada de chamadas de transferência, é aplicado um esquema de canal de classificação dividida às redes UMTS multimédia. Esta rede multimídia suporta duas classes de chamadas; chamadas de banda estreita que requerem um canal e chamadas de banda larga que requerem vários canais. Os canais em serviço para chamadas de banda larga são divididos em seus canais para empréstimo de chamadas originárias e chamadas de transferência de acordo com a política de controle de limites. Assumindo que as chegadas de chamadas de banda estreita e as chegadas de chamadas de banda larga são Poisson, modelamos o número de chamadas de banda estreita e o número de chamadas de banda larga em uma célula pelo processo de Quasi-Nascimento-Morte Dependente de Nível (QBD) e obtemos sua distribuição estacionária conjunta . Para análise em nível de pacote, primeiro descrevemos o tráfego de downlink da estação base para um terminal móvel em redes UMTS e calculamos o atraso médio do pacote de uma chamada de banda larga conectada usando análise QBD. Exemplos numéricos mostram que nosso esquema de canal de classificação dividida reduz a probabilidade de bloqueio da chamada originária e a probabilidade de encerramento forçado da chamada de transferência com uma pequena degradação do atraso do pacote.

Abstract: We propose and analyze a new efficient handoff scheme called Splitted-Rating Channel Scheme in UMTS networks, and we analyze the call level performance of splitted-rating channel scheme and then packet level performance of downlink traffic at UMTS circuit-switched networks. In order to reduce the blocking probability of originating calls and the forced termination probability of handoff calls, a splitted-rating channel scheme is applied to the multimedia UMTS networks. This multimedia network supports two classes of calls; narrowband call requiring one channel and wideband call requiring multiple channels. The channels in service for wideband call are splitted its channels for lending to originating call and handoff call according to threshold control policy. By assuming that arrivals of narrowband calls and arrivals of wideband calls are Poisson, we model the number of narrowband calls and the number of wideband calls in the one cell by Level Dependent Quasi-Birth-Death (QBD) process and obtain their joint stationary distribution. For packet level analysis, we first describe the downlink traffic from the base station to a mobile terminal in UMTS networks, and calculate the mean packet delay of a connected wideband call by using QBD analysis. Numerical examples show that our splitted-rating channel scheme reduces the blocking probability of originating call and the forced termination probability of handoff call with a little degradation of packet delay.
