“…La última se caracteriza por ser no tolerante a errores (tasa de error de tramas cero), y de acuerdo con [7] representa el 70% del tráfico TCP de Internet. El tráfico de voz digitalizada se modela a partir del comportamiento probabilístico del flujo digital de un codificador GSM [11], con una relación 35/65 entre voz y silencio. El flujo de 13 kbps es paquetizado en 260 bits/trama cada 20 ms. En cuanto al modelado probabilístico del tráfico web, se toma de [12] y [13].…”

Resumen--La búsqueda de un protocolo de movilidad adecuado para inter-operar con Mobile IP en redes de 3ª generación ha sido objeto de una intensa investigación. Se han analizado diversas propuestas y llevado a cabo comparaciones. Cellular IP es un fuerte contendiente para ocupar el lugar del protocolo elegido, su desempeño ha sido caracterizado principalmente con el programa Columbia IP Micromobility Software bajo diversos escenarios. Análisis previos han considerado tráficos UDP y TCP genéricos. En este trabajo se desarrolla un modelo de red de 3ª generación basado en Cellular IP, que maneja servicios de voz y web modelados en su comportamiento probabilístico para representar respectivamente, el codificador GSM y el contenido de páginas web mediante paquetes y objetos. De esta manera se obtiene un conocimiento más exacto del desempeño del protocolo Cellular IP.Palabras Clave--Internet, Sistemas celulares móviles terrestres, Programas de simulación, Protocolos.

“…The latter is non-tolerant to loses (0 frame error rate), and according to [7] amounts to the 70% of Internet TCP traffic. Digitized voice traffic is modeled after a GSM coder [7,11] probabilistic behaviour, with a 35/65 voice-silence ratio. The 13 Kbps bit stream is packetized in 260 bits/frame every 20 msec.…”

The search for a suitable micromobility protocol which will inter-work with Mobile IP in 3G mobile networks has been the subject of intense research. Several proposals have been analyzed and comparisons carried out [1]. Cellular IP is a strong contender to take the seat as the chosen micromobility protocol, and its performance has been characterized mainly with Columbia IP Micromobility Software (CIPMS) under diverse scenarios. Previous analysis have considered generic TCP and UDP traffic. In the work presented here, a Cellular IP based 3G network model is developed, and services (voice, and web) are represented after probabilistic behaviours to conform, respectively, to a GSM coder, and web content comprised of packets, objects, and pages. In this way a more accurate knowledge of Cellular IP performance can be obtained.

The access time perceived by GPRS users in a GSM/GPRS network is severely affected by the interference condition of the radio channels. In this paper we propose and analyze a frequencyhopping scheme for interference control in GPRS channels. This scheme allows GPRS packets to overflow from interferencelimited carrier channels to carrier channels with less or no interference. We have shown via numerical results that the overflow mechanism is efficient in reducing access time at interference-limited channels, with little adverse effect on the access time at interference-free channels, hence improving overall system performance.
