“…1); Handover horizontal, que se caracteriza porque las celdas, que realizan el cambio, son tecnoló-gicamente iguales, Handover Vertical, que se caracteriza porque las celdas son tecnológicamente diferentes, Soft Handoff que se caracteriza por un cambio planeado y hard handoff que se caracteriza por un cambio no planeado debido a la interrupción abrupta del enlace existente [18]. Dentro del handover horizontal existen otras dos clases; Intracell Handover, que ocurre cuando se cambia de canal de radio dentro de una misma celda para minimizar la interferencia entre canales, e Intercell Handover, que ocurre cuando se cambia de celda [18].…”

Resumen-El artículo describe las redes 4G y muestra un mapa general de su desarrollo tecnológico. Adicionalmente se muestran dos temas que son clave en el desarrollo de este tipo de redes. Estos temas son el Handover Vertical y la convergencia hacia IP. La revisión expuesta muestra el estado del arte y los antecedentes de estos temas. Con base en esto se genera un mapa conceptual en el que se considera la variedad de tecnologías que convergen en el esquema 4G.Palabras clave-Redes 4G, handoff vertical, Handover Vertical, IP Móvil.Abstract-This paper describes what the 4G networks are and depicts a technologies' general map of its development. Furthermore it shows two topics that are important in these networks' development. These topics are vertical handover and IP convergence. The depicted survey by this paper shows the state of the art and the background of these topics that generate a useful mental map due to technologies' variety that is converging in the 4G scheme.

“…To minimize the forced termination probability, conventional approaches deploy handover prioritization schemes [7] such as reserving a number of channels in each cell, named guard channels, only for arriving handovers. Given that the carried traffic diminishes as more guard channels are reserved, it is crucial to dimension its number appropriately.…”

, JM.; Pla, V. (2012). Robustness of optimal channel reservation using handover prediction in multiservice wireless networks. Wireless Networks. 18(6):621-633. doi:10.1007/s11276-012-0423-6. Wireless Networks manuscript No.(will be inserted by the editor) Robustness of optimal channel reservation using handover prediction in multiservice wireless networks Jorge Martinez-Bauset · Jose Manuel Gimenez-Guzman · Vicent Pla 2011Abstract The aim of our study is to obtain theoretical limits for the gain that can be expected when using handover prediction and to determine the sensitivity of the system performance against different parameters. We apply an averagereward reinforcement learning (RL) approach based on afterstates to the design of optimal admission control policies in mobile multimedia cellular networks where predictive information related to the occurrence of future handovers is available.We consider a type of predictor that labels active mobile terminals in the cell neighborhood a fixed amount of time before handovers are predicted to occur, which we call the anticipation time. The admission controller exploits this information to reserve resources efficiently. We show that there exists an optimum value for the anticipation time at which the highest performance gain is obtained. Although the optimum anticipation time depends on system parameters, we find that its value changes very little when the system parameters vary within a reasonable range. We also find that, in terms of system performance, deploying prediction is always advantageous when compared to a system without prediction, even when the system parameters are estimated with poor precision.
