    Abstract: Un método para uso en una red IP, la red que incluye un nodo conmutador (5), al menos un servidor DHCP (4, 4a, 4b) y al menos un abonado (6) que está asociado con el nodo, el método incluye los siguientes pasos: - crear una lista (L1) de los de confianza de los servidores DHCP; - transmitir por el abonado (6) un mensaje de petición DHCP (M3) para una dirección IP; - recibir un mensaje de respuesta (M4), el cual transporta una dirección IP de abonado asignada (IP1); - analizar (510, 808, (8)) el mensaje de respuesta para ser un mensaje DHCP y que tiene una dirección fuente (IP4) de uno de los servidores DHCP de confianza (4); - actualizar (513, 812, (10)) un filtro (9, TAB1) dinámicamente en el nodo (5), el filtro que almacena una identificación (MAC1, P1, VLAN1) del abonado (6) y la dirección IP de abonado asignada (IP1); - transmitir una trama (FR1) desde el abonado (6) usando una dirección IP fuente (IPX); - comparar en el filtro (9, TAB1) dicha dirección IP fuente con la dirección IP de abonado almacenada (IP1); - descartar dicha trama cuando dicha dirección IP fuente (IPX) difiere de la dirección IP de abonado almacenada (IP1).

    Abstract: A 2G controlling entity in a common 2G/3G network that includes a common Core Network is connected to dual mode mobile stations and to a 3G controlling entity also connected to dual mode mobile stations. The 2G controlling entity applies a 3G camping strategy and receives a service request, for a service at least supported by the 2G network, from a dual mode mobile station. The 2G controlling entity instructs the dual mode mobile station, when connected to the 2G network, to perform cell reselection evaluation of 3G network cells only when the 2G network signal strength is below a predetermined threshold.

    Abstract: Un método para usar en un nodo conmutador (5), para gestionar tramas entrantes de un abonado (6) en una redIP, incluyendo el método los siguientes pasos para ser realizados por el nodo conmutador: -recibir del abonado (6) un mensaje de petición DHCP (M3) para una dirección IP; -reenviar el mensaje de petición DHCP (M3); -recibir un mensaje de respuesta (M4), el cual transporta una dirección IP de abonado asignada (IP1); -analizar (510, 808, (8)) el mensaje de respuesta (M4) para ser un mensaje DHCP que viene de un servidor DHCPde confianza; -actualizar (513, 812, (10)) un filtro (9, TAB1) dinámicamente en el dispositivo (5), almacenando el filtro unaidentificación (MAC1, P1, VLAN1) del abonado (6) y la dirección IP de abonado asignada (IP1); -recibir (501, 801) del abonado (6) una trama en el puerto de abonado (P1); -comprobar (506, 803) cuando la trama no es un mensaje de petición DHCP (M3), si una información fuente de latrama es válida en el puerto de abonado (P1); y -descartar (507, 804) o aceptar (505, 805) dicha trama dependiendo de la información fuente de la trama.

    Abstract: Illegitimate use of IP addresses is counteracted. A network (1) includes a switch (5) with ports (P1,P2,P3) to subscribers (6,6A) and a port (PN) to a core network (2) with DHCP servers(4,4a,4b). The switch includes a database (7) and an IP filter (9). The database has MAC addresses (MAC1, MAC2), port numbers (P1, P2) and VLAN identities (VLAN1, VLAN2) for the subscribers (6,6A) and the filter has a list over trusted DHCP servers. Initially only DHCP messages from the subscribers are allowed. When the subscriber (6) requests (M1,M3) for an IP address it is checked that it is a DHCP message with valid subscriber values (MAC1,P1, VLAN1). A respond (M2,M4) with an allocated IP address (IP1) and lease time interval (Tl) is checked to come from a trusted DHCP server. If so, a list in the filter (9) with correct information is dynamically generated (MAC1, P1, VLAN1, IP1, T1). A message (M5) from the subscriber (6) with false IP address is discarded by the filter. Attempts by the subscriber to use false IP address are counted and a warning signal is generated.

    Abstract: The present invention relates to a method for co-ordination of uplink scrambling codes between different radio network controllers (21) and the assignment of such codes to radio connections (27) of user equipments (26) in a code division multiple access (CDMA) communication system. The invention also relates to methods for creating a starting vector used to generate said scrambling codes. According to the invention, a unique subset of scrambling codes is dedicated to each radio network controller (21) by assigning an offset vector (212). Initial starting vectors (215) are composed by concatenating the offset vector (212) and the binary representation of a determining value (216) within the size range of the dedicated code subset. An idle starting vector is selected, e.g., by using a one-dimensional array (217) containing a status bit for each scrambling code and by using the array index (213) as determining value (216).

    Abstract: método e dispositivo em um sistema de telecomunicações. em um método em um nó central de a rede de rádio celular, o nó central é adaptado para decidir se uma estação móvel conectada à rede de rádio celular através de uma primeira tecnologia de acesso de rádio controlada pelo nó central deve ser movida para uma outra tecnologia de acesso de rádio quando uma chamada comutada por circuito da estação móvel é terminada. considera-se que a rede de rádio celular é adaptada para usar um sistema de apoio para procedimento de comutação por circuito. primeiro, é decidido que uma chamada cs para uma estação móvel particular terminou. então, verifica-se se a chamada cs foi o resultado de um sistema de apoio para procedimento de cs. o nó central, então, decide se a estação móvel deve ser movida para uma outra tecnologia de acesso de rádio com base pelo menos parcialmente se, isto é, se a chamada cs foi um resultado de um procedimento de sistema de apoio de cs.
